THERMAL PRODUCTS CO

Thermal Products Company is a Natick, Massachusetts window and siding outfit that reviewers know almost entirely through one name: owner Doug Ross. Windows and storm doors are the recurring thread across its written record — replacement window jobs, cracked-pane fixes, and door swaps, run personally or with a small crew. Its BuildZoom record spans eight years and just three reviews, averaging 3 out of 5 stars. The strongest account is a 2015 review describing Doug Ross as prompt for the estimate and efficient on the job, with pricing that ran about half of what a big-box retailer quoted for a round of replacement windows and, three years later, two storm doors; a couple of minor installation issues came up and were resolved. A 2023 review told a similar story on the install side — a crew member named Victor did a good job putting in four replacement windows and swapped a cracked one quickly — though that homeowner was left confused about whether the windows actually qualified for the Federal Tax Credit for energy efficiency. Worth knowing before calling: a 2018 review described a different experience. A customer with a 2011 window installation under a lifetime warranty said repeated calls and texts to Doug Ross about a slider window that wouldn't lock went largely unanswered, and the repair was eventually done by someone else. BuildZoom also lists a Massachusetts home improvement contractor registration for the company, shown there as inactive. For straightforward window or storm-door replacement, the pricing and installation quality described here are real positives — just confirm current licensing and ask directly how the company handles a warranty callback before signing anything.
