Thermal Specialties did a fantastic job replacing several windows in my home. The owner, Stephen, was very honest, responsive and helpful in explaining various options and brands without trying to up-sell for more expensive windows. 
The installation staff arrived promptly as schedule and completed the work in a day. The workmanship and quality was excellent. I'm planning to use TSI to replace some additional windows later this year.

Frank in the crew arrived on time and with all the materials. They explained what they were going to do and immediately started the work. They replaced all the windows and the sliding door and they were very professional and they cleaned the areas very well. They left the house cleaner than when they came. Except for the beautiful windows and door, you could not tell that the house was a work site. I am very satisfied with the work they did and I am already discussing with TSI to come back within 3 weeks to install doors to the deck.

Steve the owner came to house day after initial contact. He spent approx 2 1/2 hours explaining options and left quote. We slept on it a couple of days, did research and asked for a slightly lower price. He agreed and picked up contract.

One week after contract was executed installer came to note exact measurements and answered questions.

Install approx 3 week after contract executed, exactly as promised.

Large crew was exactly on time (7:30A) and worked non-stop for the day. The house and grounds were spotless after cleanup. Friendly, professional. Answered questions as work progressed.

Interruption to household routine was minimal. We had moved certain items away from the windows as instructed and there were no issues.

Two thumbs up. Highly recommended.

It went very smoothly.  The communications before the installation were timely and helpful.  The installers showed up on time and worked quickly and professionally.  The work was completed on time, on budget, and no follow up visits were required.  I was looking for a company that was locally owned with some quality control over the installers (as compared to a chain store).  They met my expectations and plan to use them to replace the other windows in my house.

It went great. These guys are professional, helpful and went out of their way to keep things neat and tidy. They also helped keep the house as warm as possible. It was 40 degrees the day they put in the new windows and I only had to put on an extra sweater while they were installing all the windows throughout the house.

Cost estimates, windows and installation were all on-time. 

Owner came out to provide estimate.  He was professional, knowledgeable and helpful.  Answered all of our questions and provided a couple cost effective solutions for our needs.

Installers were professional, quick, respectful of our living space.  The 8 windows were installed in less than half a day and look amazing.

We had several estimates from different companies including Thermal Specialties.  Lots of useful information and advises.  Steve was very honest.  He observed our house and told us that the lower quality window does the job and did not push for higher quality windows. Negotiation went smoothly.  No pressure.  He responded quickly on questions, application process and scheduling for installation.  Although there were some communication difficulties when rescheduling the installation date due to weather, but eventually everything went ok.  Installation was prompt and quickly.  Installation contractors came to our house little before 8 as scheduled and completed it before 2.  Very efficient.  They cleaned the rooms and patio after the installation.

From start to finish, my wife and I were thoroughly impressed by TSI. First, the owner, Steve,  personally came out on a Saturday morning to demo his products - Energy Star-rated by the way!  Steve was extremely professional and knowledgeable about the products and the entire installation process. The crew that later installed the windows were also superb: they took extra care whenever entering our home, used drop cloths, and even vacuumed the floor along the way. The windows look fantastic and we could not be happier!

We give our unequivocal recommendation for TSI to anyone in need of windows or the company's other services. Thanks again Steve, Frank, and your entire team!

Met with TSI representative Mr. Plumley. He was very matter of fact and not overbearing as some in marketing are. He offered a good value for the insulation we needed and the price we agreed upon. I recommend TSI.

Pro was on time, delivered services as promised. His insulation crew made every effort to inconvenience us as little as possible and left no mess. The attic fan installer accomodated our scheduling needs and provided an excellent product and service. His pricing was slightly higher than others but he had more higher ratings also.
