KTL Pro Builders - General Contractor Worcester

KTL Pro Builders is a Worcester general contractor and remodeler run by William Emase, based at 373 Mill St, and nearly every review on file is about the same kind of job: finishing a basement. Massachusetts registers the company's home improvement contractor license (HIC #217777) as active, with Emase as the license holder, and Thumbtack shows a background check completed under his name. The reviews line up around that basement work. A June 2026 Google review says the crew "transformed our basement into a stunning living area," and several Thumbtack accounts from May and June 2026 describe turning an unfinished basement into a guest suite or entertainment space with custom details and clean, modern finishes. A separate November 2025 Google review credits the same crew with a neat, respectful interior-painting job on a kitchen and hallway. All sixteen Google and Thumbtack reviews on file are five stars with none negative — but several of the Thumbtack basement testimonials use strikingly similar phrasing, so that five-star count reflects a narrower range of distinct voices than the raw number implies. Two things are worth clearing up before hiring. Angi's profile claims 15+ years of experience, while BBB describes KTL as roughly a year in business — those two accounts of the company's history don't match, and it's worth asking Emase directly which is accurate. Separately, the company's own website is still a bare "under construction" placeholder, so BBB, Angi, the Worcester Chamber of Commerce directory, and Thumbtack are currently the only outside places to check on the business; there's nothing on the company's own site yet to compare against. For a Worcester homeowner planning a basement remodel or interior painting, the license checks out and the reviews about the finished work are consistently positive. Given the similar-sounding testimonials and the short, disputed track record, it's worth asking for a couple of independent references and getting a clear answer on how long the company has actually been operating before booking.
