What Our Customers Says

We strive to make the entire home remodeling experience positive for our customers—from your first phone call, until the final handshake.

If I could give Aaron, Bob and his crew more than 5 stars, I absolutely would. Everyone was incredibly professional, punctual, conscientious and a delight to have on the project. I work in the construction field as an attorney and I have heard horror stories. This was a smooth experience and the finish on the house is really top notch. Bob and his team don’t just finish a job, they make sure it’s aesthetically pleasing and met my impossible standards. I have an eagle eye for details and their work exceeded expectations. We had every window replaced and put on James Hardie siding. They even repaired part of our roof. I never write reviews because I’m usually very underwhelmed, but I had to take the time for this review. If you are on the fence with contractors, look no further. It is a no-brainer to retain Thermo-Seal. (As a side note, my very young kids know Bob by name - which should indicate that he’s a fantastic part of the Project that is always showing up!)

We hired Thermo-Seal for new windows and siding and I could not be happier!!! Aaron and Bob have been a pleasure to work with- their team is on time, professional, and meticulous about their work. You can tell they take pride in their output and ensure things are done correctly the first time around. Pricing is competitive and even when we ran into a slight snag (as you typically would expect from a 100+ year old home), both Aaron and Bob were very fair. The Project completed ahead of schedule and Bob kept us in the loop the entire time. Very happy with their work and highly recommended!!!

We talked to a few Companies that sold James Hardee siding but Aaron sold us with his knowledge and confidence. He was not wrong he delivered everything he promised. We had some issues with our house. They explained them communicated and we were never pressured. Our house and roof look amazing. They even replaced an old skylight. The staff were all incredible, proud of their work, professional, friendly and they cleaned up each night. Bob the General contractor was also amazing. Always picked up the phone, checking in on the project and with us. It has been a long time since I worked with such a competent company. It's rare these days, which is why I was willing to write this review. I would give them 10 stars!!

We shopped around and discovered Aaron and his team through a FB group. We really appreciated that Aaron was able to measure and order our windows quickly and received all 21 of our windows in 8 weeks. Other vendors were quoting us 24-26 weeks! Installation was seamless and the quality of the Harvey windows is top notch. I felt like the price was extremely reasonable, if not less than competitors. The installers were courteous, experienced and real pros. Aaron was always available for a phone call or via text. Everyone on his team is a great communicator. We appreciated the whole experience from start to finish. You won't be disappointed!

Thermo-Seal was scheduled to side our house when in one of the many storms this spring, our roof got damaged. We hired Thermo-Seal to do both jobs and could not be more pleased. The crew was efficient and neat on both jobs. The general manager Bob was on site to answer any questions or concerns that we had. They also took care of all of the paperwork for our insurance company for the roof and that was a blessing. We would highly recommend Thermo-Seal to anyone who needs work done. The owner Aaron is very proud of his company and it shows in the work that the company does and the pride that his workers take. Love them!!!!!!

What a GREAT company windows are beautiful and the workers did an absolute perfect job, clean, neat, and finished off beautifully. They even touched up with my paint and seemed to enjoy going the extra mile to please...Aaron is an great guy who loves what he does and is proud of the company and his family of workers. I would recommend Thermoseal windows and siding to anyone who wants quality work at great prices.

Bill W.

From FACEBOOK

Aaron and his crew were a pleasure to work with and we love our new windows. The installation was efficient and the team was very professional. I’ve seen a difference in my heating bill since the install, which was our primary goal so we are very happy so far! Aaron even had a custom design made for us that matches the antique original windows of our 100+ year-old house. I will work with Aaron and Thermo-Seal again on a front door replacement when the time comes.

Aaron was always very responsive and on top of hus game. We are very pleased with the final result and would highly recommend him and his crew.

From YELP

I'm so happy with my new windows! My only regret is that I don't have more windows to replace! Aaron and his team were a dream to work with - communicative, friendly, and direct. They worked with me to scope out exactly what I wanted and they were very transparent and fair on price. The installation team was efficient and respectful, making sure everything was done to the utmost standards. My windows look amazing but more importantly they work fantastically! I was shocked at how much quieter and cooler my house was after the new windows were installed, and they are so much easier to keep clean. I will be recommending Thermo-Seal to everyone!!

Carly W.

From YELP

Where can we begin with Aaron and his team? What drew us to him initially was his responsiveness in our hour of need - as water poured into our bedroom through cheap, poorly installed windows. Aaron talked me through immediate solutions even before it was clear we would hire his company. Once they got in to see, he guided us through every step of the process to fix the problem and replace two of our windows. We appreciated that he called to check in frequently when his team was on-site, and that he is responsive over text. His team is also highly capable, friendly, and trustworthy. We look forward to doing more business with Thermo-Seal in the near future!
