Celtic Home Improvement

Celtic Home Improvement is a Lynn-based renovation contractor run by David Sheehan, in business 38 years since 1988 according to the Better Business Bureau, handling bathrooms, kitchens, masonry, decks, additions, and general home repairs. A March 2026 Google review calls the service wonderful and says the company has never let the reviewer down across repeated jobs replacing and refurbishing parts of their home. The Better Business Bureau separately notes recent positive reviews specifically about window installation and basement finishing, though it doesn't quote them directly. In an August 2025 Nextdoor post, a Wilmington resident recommended the company by name, describing it as an unrestricted construction supervisor license holder with an HIC registration, fully insured, and celebrating its 40th anniversary — details from that poster's own account rather than an independent check. There's no negative account here to weigh against the positive ones, though the written history is thin: just one review directly quoted, alongside a scattering of directory listings with no real content. The Better Business Bureau notes the company isn't BBB-accredited and carries no formal BBB rating. For a broad range of renovation work — additions, kitchens, bathrooms, decks, and repairs — the accounts on file are positive and the business has a long local history, though anyone hiring should confirm current licensing and insurance directly rather than relying on a third party's description of it.
