    Alde B.
  • Dave was very professional. He answered all of my questions willingly & helpfully.

    Heath Himsedt
  • Installer did a great job. His clean up was very good.

    Lou Lira
  • From the moment we met Jim Ross who was always sincere, friendly and professional through the entire process and was executed without an issue. The entire crew Ole Olson, his son Gage and anyone else who stepped in, were hard working, a true team effort, all great. Our rating goes way beyond 5 stars. Wish all companies, contractors and crews could be this good working with passion and perfection to build something to be enjoyed for years to come. We highly recommend them and plan in the future to call upon them.
    Thanks you for job well done!!

  • Matt and Sigo put siding on our house finishing it today and we want others to know how good these two individuals are:
    1.       They were never late and didn’t take breaks.
    2.       They were always polite and considerate.
    3.       They were always precise and competent on their work.
    4.       They always paid attention to all details.
    5.       They always cleaned up as best they could at the end of the day.
    6.       They both have the highest work ethic.
    7.       They work very quickly and efficiently turning a five-day job into three.
    We recommend both Matt and Sigo without any reservation.

  • Dave is fabulous! Very meticulous and thoughtful. He walked us through every detail and also worked through every challenge of the install. Thank you Steve and Joyce! You are all awesome!

  • We contracted with Nat’l Home Improvement to handle several improvements/repairs. Steve Becker came to our home and did a very thorough inspection. He guided us through making the best choices for our improvements/repairs, how the insurance processed worked and helped us get the best possible price for the items insurance didn’t cover. Nat’l Home Improvement worked directly with our insurance company regarding hail damage related improvements and directly with us regarding general maintenance improvements. Steve and his staff were very professional. Nat’l Home Improvement didn’t have any hidden fees and stuck to their quoted price. We were extremely satisfied when the job was done. We would recommend Nat’l Home Improvement.

  • There’s always a certain amount of anxiety associated with projects like these, and this was the first time for me to go through it by myself. I found that right away I felt at ease and that continued throughout the duration of the install.
    From my initial contact with Joyce (in the office) to my in-home informational visit with Howard, to the final install, the only negative was waiting for the windows to arrive!! These folks made me comfortable with asking questions and having concerns that come with being a forst-time window replacement recipient!
    My installer, Dave, was prompt, courteous, professional, cleaned up work areas as he went along, had diligent attention to detail and answered any questions I had without making me feel silly for asking. I was unable to be in my home for most of Sunday while he finished the project, but I felt totally confident and at ease with him being there. He locked up my home and exited the premises as we had discussed. All these characteristics were/are very important to me and I was not disappointed.
    I’ve already shared my more-than-positive experience with many people (yesterday and today). I had several e-mails waiting for me this morning that asked how it all went. It was with great pleasure that I told them, and they e-mailed back and asked for the company name and contact information. I hope for them (and for you) that many others will get to experience the excellence that came with doing business with National Home Improvement. A quality establishment from beginning to end.

  • I would like to thank you and your highly professional and courteous crew for the excellent work done during the re-siding of my home in Ken Caryl Ranch. After the siding was complete and the final inspection had been made by the foreman, I personally did a walk-around and began to appreciate the high quality of material and workmanship. Interested in other re-siding jobs in the neighborhood, I took a walk around our block and a couple of others. None came close to matching the attention to detail or was as finely finished as your work.
    During the siding project, I had many requests for your crew. These minor interruptions were always met with patience and compliance when necessary. If the foreman was not on site, he was available immediately by cell phone. I guess my greatest concern was the yard clean-up after the work was finished. Naturally, the removal of old siding, exterior wall repair when necessary and the installation or new siding is a debris-rich operation. At the conclusion of the job, the house looked brand new and the yard looked entirely untouched. I’m impressed!
    After other bids had been received, your business was chosen as the result of our identification of what you might call “best business practices.” Initial appointments and timely follow-ups, promises made and kept, superior knowledge of your product, the availability of additional services and products, a refreshing customer service ethic…all of these put your company at the top of our list.
    Thanks again…and please call upon us to either show our home or provide a recommendation for potential customers of National Home Improvement, Denver.

  • Thanks for the quick response! You must be a great company to work for as the repair was done by the same person who did the original installation “Way back when.”

    Sue
  • We are delighted with completion of the job and the windows. Your crew was knowledgable, polite and thorough. Joyce’s exceptional customer service represents your company positively to all.

    David & Linda Blandin
  • Awesome job, awesome windows!! This company is the very best, from the sales to the installation, all went so smoothly and easily! Love it and thanks again.

    Lauri LaBadie
  • This was our third time using National Home Improvement for replacement windows in our home. They replaced all of our second story windows several years ago and did a good job. When we remodeled our kitchen and family room a few years back, National made and installed large custom picture windows to replace our old sliders. The windows are of excellent quality and the work was done professionally, on-time and for a good price. The recent hail storm destroyed several of our windows, and we again hired National to replace the damaged windows. We are very pleased with their work. The installers were seasoned professionals who did high quality work. They showed up on time and completed the job quickly. National gets a high grade for good communication, good work, and good pricing. We would definitely recommend them to our neighbors.

  • Everything looks just beautiful. It was a pleasure doing business with you and your crew as well. All the gentlemen that came and worked here were very hard workers and very professional. Good luck in the future.

  • Wonderful & trustworthy. Wouldn’t consider using anyone else!!!

    Pat & Dani
  • Joyce was GREAT to work with, she understood our short time line (the house was being put on the market to sell and we were needing to relocation with my company). Your installer was also Great. He was quick, he was friendly…. no fuss, no muss.
    Joyce worked with me through Insurance and Relocation Company issues and helped my my life a whole lot easier.

    Gerald & Linda Marcell
  • I just wanted to get a note of thanks out to all of you for the great job you all did on our recent installation of siding and fascia at our home.
    We did our research ahead of time and contacted and interviewed several companies and we are so pleased that we definitely made the best decision on which we should use. From the initial contact for a quote to the final installation everything was done “first class” and to our total satisfaction.
    Matt and his crew were wonderful (professional and curious) and Joyce at your office was also great.
    Thanks to you all this was a great experience and we appreciate all you did.

    Leonard & Millie
  • Steve & Joyce,
    Thank you very much for all that you have done. You both were very helpful in this whole process and I’m very pleased with the work completed. I’m very grateful to have dealt with such an honest and high integrity company.

  • The windows are beautiful and the guys were great.
    Thank Matt, Dan, Robbie and Joe for us.
    Hopefully, we will be able to replace more windows this summer.

    Joan K.
  • We are so glad we found you many years ago when we needed help with projects around our house. Every time we contacted National Home Improvement we knew what to expect, professionalism at its best. Always getting phone calls or email prior to any work being done and working l¥Ound our schedule if appointments needed to be changed.
    Dealing with insurance claims can be very daunting for the average homeowner especially when the claim is over 30,000.00 requires a lot of time and paperwork, both of you made this a seamless process doing this for us, thank you very much.
    Thanks you Joyce and Steve we know you spent a lot of hard work in getting this project put together. Please thank all your contractors that helped with our huge project they all listened to us knowing exactly what we expected with each phase.
    Again, thank you!

    Fred & Ida F.
  • Thanks for the great Roof Job! Loved the team!! Very respectful and conscientious. Appreciate it!

    Jean
  • Thank you for all your good work. The painters, roofers, gutter people, window installers. Especially the office people and you Steve. Thank you Joyce. I am so glad I chose your company.

    Rose Marie
  • Just wanted to say thank you again and on the last project of 25 Grant St we really were happy with the install guys. Clean quick and professional.

    Shockcor Inc
  • I was referred by one of [my] customers in the electrical industry. Everything he said was absolutely true, professional, quick and quality work. Dave, my installer, was very professional and delivered what he promised. The windows are quality and the install was excellent. Very pleased.

    H. Espinoza
  • Though I don’t want to open a Google account, I do want to share with you that I had the very best experience with your company, from start to finish. Your folks did what they said they would, when they said they would, and did it politely & professionally. I would 100% recommend your company.

    Verna P.
  • Steve, Joyce, and everyone else,
    Once again, I am reminded why we picked you guys for our siding and roof after you did our windows. And why we have recommended you to anyone who has asked about our experience.
    Joyce really came through and was able to walk me through popping our window back in with little fuss (and whatever fuss there was came from my side) and no waiting. I can’t tell you how much I appreciate your quick response times and great service-even long after the sale has been made.
    Thanks again!

  • Excellent communication and professionalism. From the first meeting to plan the deck to the final completion, this team was amazing to work with. They were helpful, troubleshooted with us, responsible, diligent, reliable, super friendly and professional. We are thrilled with the outcome and the process. We have neighbors who are very impressed as well and are considering this company for future projects.

    Kristine P.
  • Excellent installation. Very positive experience.

    Diane L.
  • Matt & Nyamjay are two very professional installers. They are very hard and meticulous workers. You are blessed to have them as a team for your company.

  • Great company, helpful, efficient and honest!

    Amanda S.
  • Excellent job with windows, patio door, and siding, and gutters, Completed on-time and as planned, with no surprises or delays.

    James O.
  • Steve was very professional from the initial meeting. The correct measurements were taken that first day, and this was a seller! All of the others promised a "true measurement withing a week after ordering." We also chose this company because it is a neighborhood business, and we feel this is important. The only drawback was a little bit of miscommunication with the installer, but Dave did an awesome job and was able the complete the job in great time! Thanx for the great work. We've already given their phone number out to friends.

    Carol K.
  • Everything went smooth and was happy to work them putting up our siding.

    Denver homeowner
  • I chose this pro because he brought up the topic of possible lead problems. He was well priced and did a great job.

  • Very reliable and Joyce at the office was wonderful and very helpful. Went the extra mile for us.

    Freida F.
  • We used National for every part of the project. They helped us design our kitchen to the construction of every part of our house. We did our kitchen, our windows and our siding. National is truly a five star company. Everything from the the communication to the quality of the work was just great! I would recommend them to anyone who wants detailed work.

    Michael A.
  • National Home Improvements did an amazing job on my house. We are very pleased with the workmanship on the roof, windows, and vinyl siding. Excellent workmanship. They finished on time and the clean up was great. Ralph came on time and was prepared with samples and colors of various types of vinyl siding and roofing material. I give National a 5 star rating and would highly recommend them.

    Diane W.
  • Ralph and his crew did it all and it came out fabulous. We had a new kitchen put in and new roof and siding. They took care of everything. Each crew member that came in was extremely professional and very talented. Ralph always took the time to answer all our questions and concerns. We could not have had a better experience with our project!

    Doris C.
  • Excellent windows and great installation, should have done this years ago..Thanks.

    Seyd H.
  • I have used National Home Improvement on four (4) separate occasions. Two jobs were insurance claims and the other two jobs were for home improvements. NHI handled the insurance claims totally and did a superb job. The claims dealt with roofing, siding, gutters, windows, and doors. The other two jobs were for roofing and gutters on a second home.
    All the work was done in a very professional manor and on time. NHI is great with communicating and setting reasonable schedules for the work. Steve Becker is the owner and Joyce is his office staff. I will continue to use NHI for all future home improvement jobs. I have also referred NHI to friends and neighbors who have also used their services.
    I highly recommend them for insurance claims related to storms/hail damage. You won't be disappointed.

    Patty J.
  • It's truly rare to find a home improvement contractor that takes the extra steps in their work to add value to a home. After working with National Home Improvement, this is a company with great people who are that rare find. I will happily recommend them to anyone.

    Frank S.
  • National Home Improvement replaced the windows in our home several years ago. When we decided to put up vinyl siding rather than painting our house again, they were one of our first choices.
    At each step along the way, NHI had patience with endless questions (some of them probably stupid-but I knew nothing about siding before we started) and my challenging schedule (I work out of town nearly every week). When Steve came out to measure so that he could order materials, he found hail damage on our roof that required that a roof replacement be added to the work.
    NHI worked directly with our insurance on the roof replacement, leaving us free to ask about a billion MORE questions.
    The schedule for the roofing was difficult as the rainy spring kept delaying the planned start. But once they were able to start, the job went smoothly and quickly. And then we moved on to the siding, which also went very well.
    There was a miscommunication (on my part) about the size of one of the shutters, and it had to be reordered and installed. Despite the fact that it was my fault, they managed to come out and fix the issue within a week.
    I also have to mention that Joyce and Christy in the office are great. It is nice to be able to reach out and have someone in the office to answer questions rather than having to try to catch the contractor between sales calls and jobs.
    Our house looks great now! I highly recommend NHI for your window, siding, roofing and gutters. We couldn't be more pleased with the job they have done on our house.

  • I have used National Home Improvement, Inc., since the late 90's for window replacement, siding, gutters, and roofing on 3 different residences. Steve Becker of National Home Improvement is the most honest and open person I have ever had the pleasure to deal with. Steve gives more than 100% and actually cares about his customers! Joyce in the office is very knowledgeable and helpful even during National's busy times of the year. If she does not know the answer to a question she will get back to you with an answer! I highly recommend this company for your home improvement projects. You will get a competitive price and quality craftsmanship from this contractor.

    Neal A.
  • NHI was our contractor for our extensive hail damage. They worked with our insurance to get the most money possible to cover the cost of a new roof, new bay window, gutters, and vinyl siding. Steve, the owner, was great to work with. His workers did a fabulous job both in quality and timeliness. I give this company my highest recommendation.

    Jeff C.
  • This company is wonderful. They took their time explaining and the work and details. They take pride in their work. I have never had such a great feeling with this company, their work is impeccable, and the workers are very polite and I would highly recommend this company. It was a pleasure doing business with them. I will tell everyone I know what a wonderful job they did.

    Melody C.
  • Very reputable company. They worked very hard to get the most from my insurance company for my claim. The contractors they used were very responsible with excellent work. They were all very concerned that I was happy with the work that they did. I would definitely recommend NHI to anyone for work they need on their home.

    Russell A.
  • I'm really a tough customer and if it isn't done to my satisfaction, it will be. Steve took everything in stride and made sure my roof was done with excellence, my house was painted like Picasso, and my deck roof was done to perfection. Oh, and he got the insurance company to replace my air conditioner because of all the hail damage. Nope, he probably doesn't want any more customers like me, but I believe in doing a job with excellence and being responsible for the work. That's accountability and NHI has it.
