Why Thermal Products of MA?


Customer Satisfaction!I am Doug Ross, owner of Thermal Products of Natick. Since 1986 I have put my customers first, providing great service and quality products at the lowest prices.

I founded Thermal Products of Natick in 1986, a home improvement company specializing in windows, vinyl siding, roofing, gutters, porches, and decks. I started my career working for another home improvement company, where I received valuable training and knowledge. I soon realized what this specific industry needed, which is a fair and honest company which gave, fair and honest pricing without taking one cent until the job was done to the homeowner's satification.


This is why I started Thermal Products 23 years ago and have over 6,000 satisified customers all over the New England area. I feel I have the highest quality materials and the most qualified installers in the industry, who have the best training possible. We are also licensed and insured to benefit the homeowner and Thermal Products.


At Thermal Products we always live by our motto: If you don't have time to do it right, when will you have time to do it again.
