Steve,  John and the rest of the Nu-Concepts crew just left at 6:00 pm (and they were here around 7:30 am!). So it was a long day for them (not to mention the rain this morning). But they got the job completely done. I am amazed. John and the crew get top marks for professionalism, knowledge, care and worth ethic. They are all top notch. Everything is cleaned up. The moldy Caradco windows are gone. The Marvin windows look gorgeous. What a completely fabulous job! Thanks again, Steve.

Believe it or not, Ken from Nu-Concepts waited 8 years for us to finally move forward on replacing our home windows! He was extremely professional, informative, helpful AND "patient" over the 8 years. Ken continued to check in via email and phone calls over the years without being obtrusive. We had received 2 other bids from other companies at the same time we got Nu Concepts first bid, but neither of the other companies continued to pursue our business. From the beginning, Ken listened to what we wanted offering numerous options within our budget, and then, understood when we kept placing the window project "on hold". Once the decision was made to finally start the project, Nu-Concepts convinced us they were the experts to choose. What a good decision on our part, as the installers were extremely competent and hard working. A week after installation, a painter we were using, accidently broke a part of a new window creating issues. Nu-Concepts (Steve the owner) came out and inspected the problem, and though the issue was not their fault, they replaced the part and fixed for us at no cost. I highly recommend Nu-Concepts for their expertise, integrity, and customer focused service.

My husband and I highly recommend this window company. They have installed every window, of different types, in our home, from standard living room/bedroom windows, sliding glass doors, a bay window, and floor to ceiling kitchen windows. The pricing is competitive, and they use high quality products. The service is impeccable, and delivery/installation is timely. The installers are professional, and are also very well trained carpenters. The attention to detail and symmetry of installation is flawless. Our energy bills have decreased since having their windows in our home. We would not even consider using another window company with Nu-Concepts being in the neighborhood!


Dec 2016 - John Corrorar

Had contacted Ken several years ago to design and quote exterior update/refresh; I was unable to complete at the time. Reconnected recently, picked-up where we'd left off and completed the projects. Long-time coming, but worth the wait and investment thus far. Ken and the talented crew are service-oriented, responsive and seemingly "nice, good" people who take pride in their work. We've recently compliments and inquiries; would recommend their services. With more projects to come, Ken and Nu-Concepts will be my first call.


Nov 2016 - Lisa Milligan

We used Nu Concepts to install our portico. It looks absolutely amazing and really adds dimension to our home. Ken was great to work with, very responsive, fair, and knowledgeable with his craft. His contractors who did the job were excellent and super efficient. Highly recommend!! This is what these guys specialize in and it shows.


Nov -2016 Alicia Sturges

Nu-Concepts recently completed a portico and bay window replacement in my home. From the moment I contacted them regarding an estimate they were extremely timely in responding to me. The crew was great, the work was completed in a timely manner, and I'm extremely pleased with the finished product. I would recommend to anyone and will contact them for any of my future needs.


Oct 2016 - Gigi - Lake Forest

I am super impressed with this company!!! Not only was Ken on time and responsive to my phone calls and emails, but his team did an amazing job installing our new sliding glass door and a beautiful oak front door. They were fast, polite and cleaned up thoroughly. His company and employees are professional and Ken knows every aspect of the door business.

What really sold me on his company is that he helped me select the best door styles for what my family needed and the prices are reasonable. Not cheap. But a great value for the work. I highly recommend Nu-Concepts to anyone interested in great products with great service.


June 2016 - Tim and Teresa - Arlington Heights

Steve,   I wanted to drop you this note to let you know that the installation of our three kitchen windows was just completed and they look fabulous. I must say that I am always a little nervous when I am out of town and I have contractors at the house.  

I just spoke to my wife and she could not have been more pleased with their promptness, professional attitude and attention to detail.  They carefully laid down sheeting on the floor to protect their walkways and cleaned up their area as if they were never there.  At the completion of the installation, the crew walked through the operation of each window type and verified all windows sealed correctly and operated smoothly.  

Thanks again for the wonderful service!  

Best Regards,

Nu Concepts Window Co. Sided our home and garage with James Hardieboard Siding. Installed new gutters, downspouts, attic vents, garage window, front door and back storm door.

Our initial contact with Nu-Concepts was through their website asking for a quote, within hours Ken had replied to my email and we set up a meeting time to discuss our concerns. Ken came out listened to our thoughts and desires, took some pictures and returned approximately a week later with ideas and pricing. We signed the contract, put down a deposit and work began a few week later.

Mauritz and his crew were simply amazing, these guys worked through the worst of weather...of course we hadn't had much bad weather until we started our job; snow, sleet, rain and then the massive melting (imagine working under the soffits with no gutters). Every day discussed the job process for that day, came to the door one day and apologized for going home (it was raining and miserable--I don't think I would have even attempted that day) but these guys were very conscience. Every day our driveway, garage and yard were cleared of debris and they kept their recyclables (gutters & downspouts) in one location at the back of our home until ready to haul away and respected our request to be able to put one car in the garage in the evening. We of course custom- ordered a front door and that took several weeks to come in, and as soon as that was in they came back and installed, which is gorgeous at this time they took care of some details that I had noticed that I had wanted addressed. Mauritz would have come back prior to door installation if they were pressing, but we felt that we could wait until the door was installed, which gave us more time to review the job.

I would definitely recommend this company, I was very pleased with the contact we had with Ken and how he addressed each concern, like it was his own home.


April  2016  - Stephanie and Adam Kneisler - Barrington

We recently purchased our new home and felt like something was missing from the exterior. We had always admired the curb appeal of our neighbor's house and learned that Nu-Concepts had completely transformed the exterior of their home. We reached out to Nu-Concepts and immediately heard from Ken and shortly after, he made a house call to give us more information and a quote regarding constructing a portico.

We were impressed by Ken's enthusiasm for his work and his passion for his customers and quality, not to mention the incredible "before and afters" we saw both on the Nu-Concepts website and driving around to the many homes Nu-Concepts had done in our area. Within a few weeks of meeting with Ken, we agreed on the project, had construction scheduled AND completed! Better yet, the entire process of working with Nu-Concept was simple and pain-free, and after remodeling our previous home from top to bottom, we know how difficult any type of construction process can be!

And the results are incredible. I feel like we have a new home - it was EXACTLY what was missing the quality and detail of the construction has left our visitors speechless. The portico has transformed our home and is currently the talk of our entire street!
It is with great pride that I recommend Nu-Concepts to anyone looking for a company that can provide quality, awe-inspiring updates to the exterior of their home.


October 2015 - Linda Mader - Libertyville, IL.

"Ken the project went beautifully. The crew showed up on time, and with a crew of 5 guys, did the whole job in one day. They custom built the portico on site. There were a few little things I asked them to change, (such as color of flashing) etc. and they were very accommodating. Although the company drew a diagram of my home with the portico beforehand so I could see what it would look like, the project turned out more beautiful than I expected. The workmanship, attention to detail and the quality is evident from the street. Another bonus I was not expecting....they covered all the wood parts with aluminum siding material, making it virtually maintenance free. The whole process was a pleasure and hassle-free!"


August 2015 -  John Shalaby - Wheeling, IL. 

"We went with Nu Concepts Windows for our Widows, Siding, and Patio Door because we felt we can trust them to do an excellent job. Ken helped us select the right siding and options to make our house look great. Someone was always on-site during the job that was able to answer our questions and ensure superb quality. The house turned out great and exactly how we envisioned. Ken was extremely helpful and very responsive through the entire process. Thanks Nu Concept Windows!"


June 2015 -  Betsey Hidaka - Glenview, IL.

“We knew we needed maintenance done on the house but were confused with all the options, i.e. colors styles, designs on the market. At the same time, we also wanted to give the house an extra lift. We were stuck on not knowing how and what to do to accomplish this objective.

When we met with Ken Polikov of NuConcepts, he included functionality AND aesthetics into a exterior plan. He provided a full scale pictorial of the required maintenance along with some suggestions for visually optimizing the result. This really helped us to make the leap forward.

Ken was easy to work with and very responsive to our needs. We were contacted regularly throughout the project to ensure everything was going well and follow up was timely. We appreciated the help in getting us to where we needed to be and are enjoying the new look. We are very happy with the outcome.”


June 2015 -  Ellen Lee – Lake Forest IL.

"Many thanks to Ken Polikov and his amazing team for their awesome work on my new doors, windows and portico construction. After experiencing a nightmare with another vendor who shut their doors suddenly (taking with them my down payment). I was referred to Ken by a friend and he was extremely patient with this rightfully nervous customer. He took the time and over communicated with me (in a good way!) during the entire process. I cannot recommend Nu Concepts enough - they offer high quality products, with professional installation, and exceptional customer service. I definitely found the right provider in the end. Thanks Ken!


May  2015 -  Ghida & Scot Neukirch - Arlington Hts,

"Ken, Scot and I want to thank you very much for the new windows that were contracted for our home from Nu Concept. We researched several contractors for the work and your company was exceptional from the start, and exceeded our expectations at the conclusion of the job. Your prompt follow-up, the crews careful and quality work, and the overall quality of construction was outstanding! We are very pleased with the windows and undoubtedly we will be recommending your company to all our friends and family.

Thank you very much for your time and hard work. We wish you and Steve continued success!"


April 2015 - Tony Ha - Northbrook

“My experience with NuConcepts has been nothing but positive. Ken Polikov proved himself to be very professional in all he does. Any questions I had were addressed immediately and appropriately. The working crew were also very professional in their work. I am very pleased with the completed work, and I would highly recommend

NuConcepts to anyone needing new siding.”


February 2015 - Suzy Festenstein - Arlington Hts,

“Ken Polikov is someone I trust as both an expert in his industry and a trustworthy client to do business. Ken listened to our needs and worked within our budget to help us replace all of the windows/sliders in our home. He is easy to partner with, the follow-up is always consistent and would not hesitate to recommend Ken or his company to others seeking home improvements in this area.”


January 2015 - Lindsey Berman - Glenview IL hired Ken as a General Contractor in 2007 , and hired Ken more than once

"Ken and Nu Concepts saved my home. He is not only a professional and expert in his field but his work crews were excellent as well. Ken did work on our house completing windows and a front door. Our house was transformed and the value of our home increased immediately. A few months later Ken also sold us some siding to fix the appearance of the North side of our house and once again he proved himself to be a great salesman and person. He was a gentleman and trustworthy. I would definitely do work with Nu Concepts and with Ken again in the future."


Sept. 2014 -  Paul Hanna - Arlington Hts,

We needed to replace a large foyer window and a double casement window
- I conducted extensive research of the market regarding window types, and installation companies and subsequently met with five companies to discuss their offerings.

I was made aware of Nu Concepts by my neighbor as they had worked with them about four years ago and had a good experience - they were happy with how the original installation had gone and more importantly, the windows and workmanship have held up very well. I met with Ken and was impressed by his soft-sell approach; he was very knowledgeable but took time to understand what the issues were that we faced and what it was that we wanted to achieve in regard to look, feel and color scheme of the final installation. Following consideration of the bid subsequently presented, Ken's presentation of Nu Concepts' capabilities, as well as the very positive endorsement of the company by my neighbor, we decided to engage Nu Concepts for our project. The foreman, John, made an advance visit to our house to measure and familiarize himself directly with what the project entailed. On the day of the installation, he and two installers arrived on time and proceeded to work diligently completing the job in one morning. They were evidently conscientious in their work and did a very nice job on our windows. They also laid down floor covering to help protect our carpets and vacuumed the work areas after they completed the work. Ken also visited during the early part of the installation.

All in all, I believe that we certainly made the right choice with Nu Concepts - they'll be our first call for future projects and I would have no hesitation in recommending them to anyone looking at replacing their windows.


August 2014 - Michele Crane - Northbrook

"I received incredible service from Ken. The door that he put in is absolutely beautiful. I get compliments on it all of the time. He is not only a wonderful businessman, he is also a trustworthy and dedicated person. His work and the work of his company is incredible."


Joanne Newman - Northbrook

"Our house needed a major face lift. The wood wasn't holding paint and the windows weren't opening. I had a vision and Ken Polikov was able to make the vision a reality. Our new siding and windows are beautiful!! Ken is great at helping add those extra touches that make the house complete. He listens to the customer and executes things spot on. His crew was neat, punctual and also went out of their way to help things run smoothly. We have received so many compliments on our home! Every time I drive up to my house I feel so thrilled! I highly recommend Ken
Polikov and Nu Concepts ! "


July 2014 - Laura and Jesee Burkhead - Deer Park

"Hats off to Nu Concepts ...The process went very smoothly. Ken always showed up on time and was extremely responsive. We interviewed 2 companies for our job and we selected Nu-Concepts based upon a couple things we really liked: Prepared a detailed rendering of our home with the recommended upgrades Broke down the initial estimate so that we could pick and choose what we wanted to do right away vs. down the road Ken was passionate about his work and was excited about updating our home (it's a dramatic before & after) Ken used constraint when presenting changes. He knew we had a budget and didn't try to sell us on too many new features. It would have been disappointing if the upgraded rendering had all kinds of features that were far out of reach.

Ken is pleasantly persistent. We probably would still be thinking about the project without his regular follow-up.
Ken was always on time and friendly. He accommodated our busy schedules and busy household. We have 2 little girls (2-year old and 9-month old), and he never seemed to mind when they demanded attention during our conversations.

Ken came to our house 3-4 times to settle all of the details of our project. We scheduled a start date for 3 weeks after the contract was signed. John, the leader of the installation crew, came to our house a few days prior to the start date to prepare for the installation. We discussed all the details that you don't really think about - shape of the gable vents, color of the soffits, lighting placement, etc. John and his crew showed up around 8am every day and left most nights by 5:30pm (which we appreciated). The crew definitely had a rhythm and was very efficient. John and Ken checked in with us regularly to make sure we were happy with the work. They finished on schedule and did a good job cleaning up the site. Ken checked back in with us a few weeks later to make sure we were happy.

Great experience!!! We will definitely use Nu-Concepts in the future"


May 2014 - Beth and Bob Zimmerman - Palatine, IL

Thanks for everything!

“We were completely satisfied with the work done by Nu-Concepts. We had an entire facelift put on the house with siding and a door installation. Ken and his crew were very attentive to our needs. Ken came out to meet with us with both his ideas and numerous samples to help us in our selections. The crew was fantastic and worked long hard days until the job was done. Ken checked in regularly and immediately addressed any concerns we had as the job progressed. We would happily recommend Nu-Concepts to others.”


April2014 - Marry Killen - Barrington

"Working with Ken on the remodel of our house was a terrific experience from both start to finish. He was honest, trustworthy and followed the plans exactly how we wanted. Very professional and very accommodating. We were impressed with Ken's professionalism and knowledge from the first time we met him - which is why we wanted him to do the work and went back to him almost a year later. First impressions mean everything and Ken certainly impressed us! I will absolutely have Ken and his company do future work for us. If you hire Ken, you will not be sorry- - he knows the true meaning of customer service!"


Deborah Danson - Evanston, IL.

"Hi Ken,
Forest and I were very happy with the work you provided in regards to our replacement windows. Your service and your knowledge surpassed any of your competition we received quotes from. Our painter was impressed with the quality of the work and how carefully the old frames were removed - the old plaster walls remained in good shape.
Please don't hesitate to have any of your potential customers contact us for a reference. We will be calling you back when we decide to move forward on the exterior of the house.. Keep up the good work."


Gail Breen - Northbrook

"Nu-Concepts is to be commended for being so thorough and for standing behind its work so completely."

Robert Menard - Arlington Heights

"Your design has increased the value of our home and continues to draw compliments from all our friends. To say we are pleased is putting it mildly!"


Joe and Joanne - Arlington Hts

"We knew we needed windows and siding but weren’t exactly sure what we wanted. Ken Polikov at Nu Concepts was great at asking the right questions to hone in on what we were looking for. The drawing really helped us see exactly what it would look like. The quotes were provided to us without pressure and they were willing to do the work in phases to whatever our budget would allow.

The installation crew were hardworking and extremely polite. They made sure all our questions were answered and made sure we knew what they would be doing and when it would be completed. We found Nu Concepts on Angie's List and would definitely recommend Nu Concepts."


Michael and Kathleen Mader - Arlington Heights

"We have received numerous compliments since the project was completed and each time we are quick to comment that this could not have been accomplished without the professional expertise of you and your staff, from design to installation."


Sue and Gary Bieda - Arlington Heights

Virginia Macdonald - Illinois State Senator (Ret.) 27th District - Arlington Heights

"You deserve the highest praise for the artistic beautification you have afforded our village. I wish... I could sponsor a resolution commending Nu-Concepts for the outstanding exterior plans and beautiful window transformations you have created in many areas of Arlington Heights."


Greg and Beth Kapka - Mt. Prospect

"The installer... did an excellent job of installing the windows taking great care to be very neat with what would normally be a messy job. He was careful with our wallpapered walls & newly stained hardwood floors."


William and Patricia Polerecky - Arlington Heights

"People we have never met before have driven to our door and complimented on the looks of our home. Friends have driven by our house because they did not recognize it. We extend a thank you to your crew for the professional job they did. They were courteous and always cleaned everything up the each day."


Dolorene and Ernie Brauchli- Morton Grove

"Thank you for the beautiful designs and detailed drawings. They helped tremendously to envision (and) imagine the end result. Your presentation about both the company and its products were thorough and professional. (We) were impressed with how complete the entire plan was. It seems you thought of every detail and put it in its proper place. WE especially like the lifetime warranty and the commitment you've made to adjust things if need."


Sandy Macarol - Arlington Heights

"(As) an interior designer for 14 years, rarely do I meet such reliable workman, truly craftsmen!!!, that are neat, on-time, perfectionists.  They gave you 150% and were here 'till 9 o'clock two night in a row and willing to make any necessary changes until the job was perfect".


George Jarik, Capital Improvement Committee - Oak Park Country Club

"Your engineers were very through in evaluating all facets of the work to be performed.  Your construction crews were extremely cooperative, working with four other contractors in scheduling the work... our appreciation for a very difficult project, done in accordance with specifications, on-time and on-budget; in a very professional manner."


Rich and Lucille McKenna - Arlington heights

"if the first point of measurement of any work is that of quality, Nu-Concepts is beyond measure.  And the obvious pride that everyone takes in their work, we believe, has made your business an art."


Bill and Debbie Mussatti - Arlington Heights

"...you took the time to sit down and talk to us, listened intently, and absorb what we were about.  The next appointment, the design concept, we were enlightened to see the detail put in to the project.
