American Thermal Window came to my rescue!

I recently had my Florida Room Windows replaced with American Thermal Windows. I was desperate after the first company that we hired to do this project dropped us like a hot potato after seeing the scope of the project.

I called A.T.W. and made an appointment not knowing what to expect.

Colleen arranged to come the following morning. She made me feel at ease almost immediately! She guaranteed that the project was going to be done without any problems. A few minutes after she had arrived, Iver, the owner of the Company showed up and assured us that the project was feasible. He personally started to take measurement etc. and came back several times to remeasure to make sure that he hadn’t missed anything.

After COVID and weather, install day finally arrived! From the start, the process was very smooth. The installers, Victor, Bruno, Kevin and Jim were excellent, hard working, efficient, experienced and friendly. The project was finished in 1 1/2 days.

The service was second to none and left me very impressed. Excellent customer service from the beginning to the end. I highly recommend them for any window projects!

American Themal has recently installed our new windows on July 2020 ahead of schedule and completed on time. The installers, Igor & Vassil, showed up on time, finish the job on time and done a very good job in cleaning up all the debris.

American Thermal did a wonderful job on my projects! I had 2 doors, a window and 2 awnings replaced. Linda was wonderful with helping schedule, plan and manage appointments. I really depended on her! Igor and Jim are master craftsmen and Jacob was an enthusiastic and able helper! They were always on time and cleaned up after themselves. I'd definitely do another project!

Bruno and Victor

Today was the first day of our windows and patio door installation. Bruno and Victor are professional and really pay attention to detail. The patio doors were installed and we love them! If the window install goes the same, you have very happy campers.

From the start of this process with Iver picking everything out, to the install.. perfect. I would absolutely recommend American Thermal Windows.

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!

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.

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.

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.

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.

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

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

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.

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!!!
