Fourteen reviews, every one of them five stars, and the same word keeps surfacing: clean. Lamothe Insulation & Contracting is a Spencer spray-foam shop, and the thing customers wrote down again and again was that the crew left the house tidier than they found it.
Robert Lamothe runs it from 15 William Casey Rd in Spencer. The work is insulation first — open- and closed-cell spray foam, blown-in and mineral wool, insulation removal, thermal and intumescent coatings — across central Massachusetts, and the company describes itself as family-owned. Its Massachusetts home improvement contractor registration, number 196452, is active and held in the company's own name.
The written accounts are specific about how the job went. A 2019 customer described an attic with two skylights reinsulated after years of heat loss, and noted the owner asked permission before starting his equipment early out of concern for the neighbours. A 2020 reviewer said the quote came back at half what competitors wanted and that the finished foam looked clean. Several 2019 reviewers wrote about the same pattern from the other end: a quote inside a day, arrival exactly on time, the job done in one visit. Customers who started with insulation kept describing him finishing other work too — a room above a garage in a 2021 review, demolition, framing, cabinets and doors in that 2020 account.
Two things to weigh. First, the written record stops in February 2022, so everything above is four or more years old — it says what this business was like then, not necessarily what booking it looks like today. Second, that most recent five-star review opens 'To be transparent, Robbie is my son-in-law', so it is family, not an arm's-length customer. And the Angi and HomeAdvisor pages are the same page twice — one set of 14 reviews, not two.
There is also a tenure mismatch worth a question: the company's site says over 20 years of experience, while BBB records a business start date of 1 May 2019 and prints 'Years in Business: 7'. Both can be true if the 20 years is the owner's career rather than the LLC's, but ask. The one item of news coverage on file is a syndicated press release the company itself issued, announcing an expansion of its service area and quoting Robert Lamothe — its own announcement, not independent reporting.
For spray foam on an attic, crawl space or rim joist in the Spencer–Worcester belt, this is a small, registry-licensed outfit with a consistent, if dated, run of specific praise for quoting fast and cleaning up. Ask for current references, confirm HIC 196452 against the Commonwealth, and pin down what the quote covers before booking.
