I recently had all my floor to ceiling, wall to wall, windows & doors replaced in my condo. I got several quotes and chose American Thermal Windows because, not only did they come in with the best price, but I really felt like RJ knew what he was doing. He spent more time explaining everything to me, measuring and listening to me warn him about the oddities of the building. He himself, with the company, had worked on this building before, so I also liked that there was first hand experience. When Bruno and Stanley and their crews came, they were friendly, professional, took care to cover furniture, carpet etc., they got right to work. The work completed as scheduled, and I am very happy with the windows and doors. They made what to me was a big scary project a positive experience. I would definitely recommend American Thermal/Sahara to anyone.

We needed to replace 6 windows in our home. Stopped by American Thermal Windows and talked to Iver Jr., made an appointment for him to come out and give us an estimate. He recommended Great Lakes eco Smart windows. Love Love Love them. The process was seamless, couldn't have found a BETTER company to work with. My wife and I like to work with Family owned neighborhood businesses and this one is a Gem!!!! Stan and Jerry were the installers they were Fantastic. Very Professional installation. I cannot say this enough about how neat and clean they were. We are so happy with the windows. They make you feel like a family member. I would HIGHLY RECOMMEND American Thermal Windows!!!!!!!!!

I have used them for doors and windows on several houses over the years. Earlier this month I had a new door installed in my Mom's house. They did a great job on a difficult install! Also the salesman knew his stuff and what was required for the area. I will continue to use them going forward

Got different quotes from some of the big name companies, but we went with American Thermal Windows because they were very understanding of our concerns and made sure to answer all of my questions. The installation and overall experience with them was very pleasant and I will definitely be referring all my friends and family about them!

by Chuck M. on American Thermal Window

We just had our second security door installed using American Thermal Window. From the initial meeting, every part of the process was professional and punctual. The quality of the doors are exceptional and the secure feeling is priceless. I would call them again in a minute!

by John F. on American Thermal Window

I ordered a new front door with a sidelight. When the door arrived, the installation was quickly scheduled. The installers Jerry and Stanley, arrived on time, installed my new door and left the area clean. They weather proofed the installation and they were efficient . The price isn't cheap but the quality of the product and the efficiency of the installers are worth the price.

by Mikki N. on American Thermal Window

I've been an American Thermal Windows customer for over 20 years! They've installed all of my windows, several interior doors and, most recently, two storm doors.

They're crews are courteous and efficient.
The company always backs there products.

Luv 'em.

by Susanna M. on American Thermal Window

My doors were installed beautifully and professionally. Not only are the frames very sturdy, but the weather resistance and energy efficiency has been improved. Both workers did a superb job and i get great joy from looking through the back sliding doors and the lovely pattern on my front door. One more thing. They removed and correctly reinstated my security pads so I didn’t have to have a special visit by my security team.

by Doris B. on American Thermal Window

Word cannot describe how satisfied we are with American Thermal Window! From initial visit to provide estimate, to visit for window measurement and final visit for installation, everything was Perfect! The Window installer named 'Victor' is super professional, efficient, considerate and a phenomenal window installer. We've had windows installed before and have never met such a quality window installer like Victor. I recommend the company to everyone!!!

by Maureen Valentine on American Thermal Window

I recently had all new windows in my house installed, and I am extremely pleased with the outcome. I had explored other window vendors, but American Thermal came out on top for service, quality, and price. From the initial site visit to the day of installation, everything went smoothly. Bruno and Victor were incredibly hard-working, efficient, experienced, respectful, and friendly and were able to complete the job sooner than expected. I feel like I have a brand new house! I highly recommend American Thermal Windows!

by M Cullotta on American Thermal Window

Stanley and Jerry door installers did an awesome job. Even the City inspector said he has never seen such a detailed job like this. I love these doors. Very professional. Also all the customer service (Dee & Ruby) were so helpful and get things done.

Excellent workmanship

I just had a huge custom two-piece window installed above my front door by America Thermal Window. Everything went smoothly, from when Tom quoted the job to installation day. I was extremely impressed with the attention to detail on the workmanship of the crew during installation. They also cleaned up very thoroughly. Reasonable prices as well. I would highly recommend ATW.

by Pete J. on American Thermal Window

I had the pleasure of doing business with American Thermal Windows. I actually had 2 storm doors installed. (Front and Rear) although I had to wait a bit for on of the doors as it had to be custom made, it was well worth the wait! The workers (Sebastian and Maciej) came and installed both doors immediately. They were incredibly fast, clean and professional in their demeanor! They took the time to explain the features of the doors and asked if I had any questions afterwards. I plan to get windows installed soon. I would definitely use ATW. Highly recommend!!!

by Antoinette T. on American Thermal Window

American Thermal Windows staff were professional and reliable from beginning to end, and I love the new windows, which look great. Everyone I talked to on the phone was polite, professional and helpful. Brian, my salesperson, did a great job explaining everything without a hard sell. My Installers Bruno, Victor, and Pablo were courteous and professional, and I really do appreciate how well they cleaned up everything after they finished. And after working with a lot of contractors who were not careful about that, leaving nails and debris everywhere, I appreciated how thoroughly they cleaned up and professional job they did. They did a great job overall, I would absolutely hire them again.

by Pam M. on American Thermal Window

Have been meaning to submit this review since November. Came across these guys a few years back when a rental property we bought needed a few more updates, so we decided to use ATW since they had provided service to the previous owners. That project went so well when it came time to replace the front door on our home. I knew who to call. I had put it off due to PTSD from my first experience some years back with Big Box, an installation from hell and an inefficient door to boot. Iver Jr pointed out the problems which totally made sense & reduced my angst considerably. The result is a beautiful modern door that operated like a vault making the difference in quality obvious. I wasn't surprised by the time frame of special order r the price as I had done my homework and had learned quite a bit. What amazed me was the professionalism of the Installers and the absolute attention to detail start to finish. Couldn't be more pleased & highly recommend.

by Misti C. on American Thermal Window

Out Condominium association recently sought to have 150+ windows replaced in our building. After several estimates, we decided to use American Thermal. The price was right! The quality of the windows is great. The install went smoothly. The workers were professional and worked neatly. And the follow thru has been fantastic. Andrea who runs the office has been very responsive throughout the process and Iver delivered exactly what we purchased. Nothing less. Pleasure doing business with them.

by Bob C. on American Thermal Window

I have had my last 3 homes and my current home services by this company. They are currently on scene installing a back door and screen door. They're the best in the business. Clean and always prompt. The doors in the back aren't even done and I can tell they are going to look great. Thanks guys for always doing a great job at my house. I appreciate it.

by Sharyl T. on American Thermal Window

I purchased a new storm/screen door and had them install it. I am extremely satisfied with the door! It's just what I wanted and Needed. The Installers did an amazing job! They were kind and very determined to make sure the door was installed perfectly. I highly recommend this company, its products, and the Installers!
