About us

We are a hands-on, quality-driven team with over 15 years of experience in the exterior remodeling industry. What truly sets us apart is simple, we are not salespeople who disappear after signing a contract and send unknown subcontractors to your home. We are the same professionals who meet you from day one, guide you through the process, and personally complete the work from start to finish. We take pride in every project as if it were our own home. Our focus is not just getting the job done, but getting it done right. With attention to detail, honest communication, and craftsmanship you can trust. We believe homeowners deserve transparency, reliability, and a team that stands behind their work. When you choose us, you're not hiring a company, you're working with dedicated professionals who genuinely care about your home and your experience.

Johnny and Josef installed a new patio door on my condo, and did a wonderful job. They are extremely professional, courteous, and considerate. I am already enjoying the finished product. I will definitely look them up again when it becomes time to replace my windows in a few months, before winter! Thank you, Thermoroom! - Kevin

Johnny was great to work with. Very efficient and excellent communication. Ordered what I needed from the manufacturer and the install was quick. No upsell or any funny business. Thank you!

6+ Room New Window Service
$12,000
We had a wonderful experience with Thermoroom from start to finish. Communication throughout the entire process was excellent, and the team was always professional, responsive, and easy to work with. The window installation itself was done with great attention to detail, and you can really tell they care about the quality of their work. Everything was installed carefully, cleaned up properly, and completed exactly as promised. It’s hard to find companies these days that genuinely take pride in what they do, but Thermoroom definitely does. I would absolutely recommend them to anyone looking for window replacement or installation work.
