M. J. Guerin Construction

Mark Guerin's own pitch is narrow and useful: older houses. His Houzz page describes M.J. Guerin Construction as a home improvement contractor specializing in older homes — kitchens, baths, roofs and painting — and the permit trail matches the general shape, with 25 projects filed between 2012 and 2023 for residential remodels, decks, roofs and kitchen and bath work across Haverhill, Methuen, Lowell, Dracut and other Massachusetts towns. Where he is based depends on which page you read. BuildZoom lists the company at 86 Crystal Lake Rd in Haverhill; Houzz puts it in Methuen. Worth confirming, though the permits cover both. No customer has written anything on either page. Houzz shows no reviews and no rating, and BuildZoom states it has received none — the score of 92 sitting there is built from permits and licence records rather than anyone's experience of the work. The licence bundle is the part to check for yourself. BuildZoom shows construction supervisor licence CS-108034 as active under its own badge, while the same page lists two different Massachusetts home improvement contractor numbers, 150735 and 176528, both described as cancelled. Five records across four types on a directory page is not a credential either way. Ask Mark Guerin for the current home improvement contractor registration and construction supervisor number and check both against the state registry before signing anything — the HIC registration is the one that governs residential remodeling work. For a kitchen or bath in an older Merrimack Valley house, the permit history is exactly the right kind: a decade of that work in the towns around him. The most recent filing is from 2023, so ask what he has built since, and for two or three recent addresses you can go look at.
