Bel Islands Home Improvement, LLC is a Marstons Mills exterior contractor working across Cape Cod, run by Andrei Yarmalovich, whose name appears in review after review. The Better Business Bureau grades the company A+ and lists it as accredited, and its BBB service list runs from asphalt shingles and red cedar roof installation through rubber roofs, vinyl and fiber-cement siding, Azek trim, seamless aluminum gutters, decks, windows, doors, additions and commercial projects.
The review record is one of the deepest on the Cape: 243 reviews on file from 2021 to 2026 across seven sources, with Google publishing a 5.0 average from 284 ratings and twelve reviews landing in the last six months alone, none negative. What makes the volume credible is how specific the bodies are — reviewers name the materials (Timbertech decking, Azek trim, Velux roof windows, unfinished cedar shingles, PVC trim), the towns (Cotuit, Sandwich, Mashpee, Chatham) and the sequence of work.
Speed is the recurring theme. A July 2026 reviewer had a roof and five skylights replaced in Cotuit; a September 2025 reviewer preparing for solar panels got a quote within a day, a start within a week, and the house and detached garage stripped and reshingled on day one. A November 2025 reviewer described a same-day site visit and a quote that followed quickly. A Cape Cod Reddit commenter in May 2024 said an 1,800 square foot roof was done in one day, and another reported a bay window installed same day.
The work is broader than roofing. Recent reviews describe full siding replacements, a dozen windows and three decks for one household, gutters, a shed sided in two days, a front and storm door, a bay window, and in one 2025 case a chemical power wash that removed years of moss and saved the owner a roof replacement. A June 2026 four-star reviewer credits Andrei's team for coordinating a kitchen remodel across a cabinet installer, a counter fabricator, an electrician, a plumber and a tiler. Several reviewers describe being told they did not need the bigger job — one says he was told in about 2016 that a few blown-off shingles did not warrant a new roof, and came back ten years later for the replacement.
What to check before booking: the company's stated tenure is inconsistent across its own listings — BBB records a 6/22/2000 start (26 years) and a 2/6/2017 incorporation, Angi and HomeAdvisor both say 25 years, and the owner's own LinkedIn describes more than 15 years and a role beginning May 2006 — so ask directly how long the LLC as such has been trading. Nothing in this evidence verifies a state Home Improvement Contractor or Construction Supervisor licence, and BBB's A+ grade is not a licence. Also note that BBB lists just one employee against a business that describes crews on multiple simultaneous projects.
For a Cape Cod homeowner wanting a roof, siding, windows, gutters or a deck done fast and cleanly by a responsive owner-run outfit, the evidence here is unusually deep and consistent. Confirm the licence number and the warranty terms in writing before you sign.
