Customer Reviews and Comments



Joe W. - Tulsa, OK
They replaced 2 sliding glass patio doors and 5 large plate glass windows. This was the last of several replacement jobs that they began in the summer of 2010 as we proceeded around the house, one room at a time, as our budget allowed. In every case, all steps, answers, surveys, quotes, measuring, scheduling, installations, products, cleanups, follow-ups, and warranty services, were of the highest quality and done professionally and courteously. They prove the old axiom, "High Quality doesn't cost; it pays!"


Steve and Mary L. - Broken Arrow, OK
Quality, manufactured locally
The windows were everything we expected them to be. Leo and his assistant installer completed a most professional job and we are so pleased with everything.


Gerald P. - Edmond, OK
Replaced all windows in the home and the patio door. The windows in the formal dining room and formal living room were huge and the measurements and manufactured windows fit perfectly and although they were big and very heavy, the installation team did a wonderful job. Came home one day to find the patio door cracked. Called George Bowers at Thermal Windows and he got a new one ordered, manufactured, and installed.


Richard S. - Broken Arrow
The installation crew did a great job and left as if they were never there. It has made a big differance in the heating/cooling and noise level from the outside. Would use them again.


Quannah H. - Norman
Our experience with this vendor was excellent. We needed to replace our 10 year-old builder grade windows for efficiency and appearance reasons. Our salesman was professional and knowledgeable and made the buying decision very easy for us. We had demos from 4 other vendors where the price ranged from $10K to $60K but Thermal Windows demonstrated a better product at a reasonable price. Our windows are very large so having them installed in the middle of winter was a concern for me but Jason and his crew worked quickly and minimized the dust and debris exceptionally well.
I would highly recommend Thermal Windows. The windows look great and we have already noticed how much quieter it is in the house. We look especially forward to a higher level of efficiency in our heating and air bills.


Jerry A. - Tulsa, OK
They did our windows and they also installed the slide window liners and sliding door.
It was very good. I was very happy with the windows. They did great work. I got a good product. I would use this service provider again in the future.


Betsy M. - Bartlesville, OK
Thermal Windows Incorporated put in a patio door. It worked out very well. They were very professional. I had a very good experience.


Ron S. - Tulsa
Large 3 section kitchen window plus smaller kitchen window. Very pleased.


Jack B. - Moore
Thermal Windows was outstanding! I would use them again.


Hamid C. - Tulsa
Wow what a difference! The new windows were a great investment. I lease this home out and the tenants were ecstatic. The windows were installed in November. The old windows were the original single pane metal framed windows. The new windows kept the house much warmer and the noise level dropped dramatically. The installers were willing to stay late and finish the job and the tenants allowed the installers to stay till 9:30 pm. The installers are very professional and knew what they were doing. They did a very good job considering the house had brick siding and some of the old windows were very difficult to take out. I checked the house in the morning and found a few minor issues. Thermal Windows was out the next day and had them taken care of immediately. The minor issues were some broken glass from the old windows got left behind, which was acceptable since the fragments would have been invisible at night. The other issue was a missing latch. Both issues were taken care of immediately. We were so impressed we have about $6000 of windows purchased for another home we own. I plan to use Thermal Windows exclusively. We had some very high end glass companies come out and the same windows would cost double the price with fiberglass frames. We were not impressed with vinyl at all since the same structural integrity as aluminum would have meant a frame twice as thick. The rep from one of the high end companies was adamant we not use aluminum frames and gave a bunch of reasons why. None of his reasons were valid. Thermal Windows' aluminum frames did not transfer the cold air from the outside into the house and they did an excellent job at eliminating noise and are great at insulating the home in the cold (the windows are low E but since it's summer can't comment on heat transfer, but low E glass is low E glass).
One last consideration to think of before you consider vinyl frames; ask yourself why modern skyscrapers do NOT use vinyl frames in their windows? Still not convinced, next time you visit a strip mall with large glass windows that have to withstand 90 mph winds, what type of frames are the windows in? If you answered aluminum you were right. If you want windows that will last you need a strong frame.


Karen R. - Owasso, OK
Thermal Windows installed new windows throughout my house. They also installed a new front door and front storm door.
Thermal Windows was excellent to work with. I changed my mind a few times on what I wanted and they were quick to accommodate. Their price was a little higher than some of the other windows I priced. However, I consider their product superior to the other windows I checked out and I was willing to pay the higher cost for better quality. Most of the other windows I priced were vinyl and I did not want a vinyl window.
I really appreciate the no pressure sales. They came to my house, gave me a bid (without telling me I had just a few days to make up my mind before the price would go up) and left me alone to make the decision.
All the installers were cordial and they did an excellent job. The installers worked with me on times that would accommodate my schedule and their schedule.
Thermal Windows will ask for a name of someone who referred you and I just happen to have a friend that used them and really liked the product. They rewarded the person that referred me. I appreciate that they understand that word of mouth is the best service a customer can give back to them.
EXCELLENT company for product and installation.


Fritz K. - Bartlesville, OK
I have used Thermal Windows, Inc. in my home and now in my rental until and am extremely please with the results. They have not only greatly improved the look of my home and condo, but they lowered the utility bills considerably. They also made my home very quiet even though my home backs up to a busy street. The installation was top notch and both times the installers were very detail oriented. They showed up on time, worked very hard, were very nice, and not only cleaned up at the end of the day, they cleaned up as they went so there was no mess made! It is very rare to find a company that no only keeps their word, but exceeds it. I not only highly recommend the windows to my friends and family, but to everyone that I talk to!!!


Debbie H. - Stillwater
They installed new windows throughout our entire house.
Initially, we saw them at the home show and were able to see samples of the windows. We chose them based on their good quality and their representation. They were able to complete the work in about eight hours and they cleaned up well after finishing. They did a good job. Our experience was just fine.


Linda S. - Oklahoma City
Replaced all the windows in the house. They were quick and efficient and the windows are great.


Debi L. - Edmond
We got quotes from 3 different providers... All of the estimates were comparable. We chose Thermal Windows, Inc. because the windows were made in Oklahoma, they provided a detailed breakdown of cost per window, and because they also provided an optional warranty for glass breakage.
We were told our windows would be made to order and we could expect them to be completed in 10 to 12 weeks. We got a letter about 8 weeks after we signed the contract letting us know the installers would be receiving the windows within the next couple of weeks. The letter detailed useful information about how long the installation would take, as well as other practical advice to get ready for the day of installation.
The workers arrived around 10 am and worked throughout the day. We had a lot of windows, so it took them a full day and a couple hours the following day to complete the job. Our old windows were original builder windows from the 1980s, and they were difficult to remove. The installers worked cheerfully and never complained about the additional work involved.
Our installers cleaned up every bit of dust and glass, and cleaned the windows as well. Each is well sealed and caulked. We could not be more pleased with our new windows! They are beautiful, and already we are noticing the air conditioner is not working as hard as it used to, and the rooms are cooler.
We would recommend this company to anyone looking for new windows. Their prices are competitive with other companies, and their professionalism and workmanship is first rate.


Linda M. - Choctaw, OK
Replaced eight 40 year old windows with new Thermal Windows
Rep for Thermal Windows came out promptly to our older home in Choctaw to give us an estimate for replacing eight 40 year old windows. This company gave us a well written estimate and very informative brochure of their product line. After getting estimates from two other well-known companies we decided that Thermal Windows was the company we wanted to do business with. Their windows are made in Oklahoma and they required only a small deposit before the windows were to be installed. It was also reassuring that Thermal Windows had a very good recommendation from Angies List. The windows were ready for installation before they had been estimated to be. The installers were prompt, worked quickly and cleaned up after themselves. The windows looked very nice after being replaced. We can definitely notice reduced noise from outside and better indoor temperature stability. They are easy to open and close and an added benefit is that the bottom section tilts in to clean the outside of the windows. One of the windows had an interior grid that had a cosmetic flaw but the company came out and fixed it and now it looks perfect. Only glitch was the time it took to get the grid replaced in the one window and the repeated communications that took place just to submit information about the problem with the window grid.


Z.Y. - Bethany, OK
Thermal Windows installed windows and doors for three of our homes.
The cost, though more pricey than some companies, is so worth it. The quality is the BEST we have ever found. George is so nice and the installation crew was very good.
