## The honest read

Sean T Collins is a Billerica roofer whose public record reads like two different businesses. On Thumbtack he's rated 4.8 from 96 reviews and hired 98 times, with recent reviews built around one theme: he shows up fast. On BuildZoom the same contractor carries a 1 out of 5 star rating from four reviews describing missed deadlines, shoddy work and, in one case, conduct a customer called unsafe.

The Thumbtack reviews are recent and specific. In a February 2026 review, a customer said Sean "came the next day" after reporting a roofing problem, then sent photos of the fix and backed it with a warranty. Reviews from mid-to-late 2025 describe the same pattern for a gutter guard installation and a soffit repair — a request made and a next-day visit scheduled within minutes. An August 2025 review credited him with fixing only the actual problem, shingles, rather than the larger insurance-funded job other roofers proposed, and called his price "more than reasonable."

The BuildZoom reviews tell a harder story. In an October 2024 review, a customer wrote that she did not feel safe with him in her home, describing dismissive, rude behavior and inappropriate texts. Two reviews from early and mid-2024 describe a deck-rebuild project that stalled for four months, missed an inspection deadline, and was abandoned mid-job with the stairs, in one customer's words, "screwed up and twisted." An older review, from 2020, described a roof leak repair that ran ten months without a fix and a promised refund that never arrived.

Both Thumbtack and BuildZoom list the same two Massachusetts license numbers for him — a Home Improvement Contractor registration (#171618) and a Construction Supervisor license (#75904) — as currently active; a third, older Home Improvement Contractor number on file is listed inactive. None of these are independently verified here, so confirm current status with the state before signing anything.

Given how far apart these accounts run, anyone considering Sean T Collins should ask pointed questions before booking: get a firm start-and-finish date in writing, ask for references beyond what's shown here, and pay attention to how the first calls are handled.

**Strengths:**
- Fast response times — Thumbtack reviewers cite next-day visits repeatedly
- Fair repair pricing — one reviewer says he avoided an unnecessary insurance job

**Concerns:**
- Safety concern reported — a 2024 review cited inappropriate texts and rude behavior
- Deck project abandoned — two 2024 reviews describe missed deadlines and shoddy work
- Unresolved roof leak — a 2020 review describes a ten-month unfixed leak and unpaid refund

**Where sources disagree:**
- BuildZoom shows a 1.0-star rating from 4 reviews describing serious misconduct and abandoned work, while Thumbtack shows a 4.8-star rating from 96 reviews praising fast, quality repairs — sharply different experiences with the same contractor across platforms
