## The honest read

Ice dams kept coming back on one homeowner's roof until Roland Martin went looking: in a 2018 review, the customer wrote that the insulation in a few visible areas turned out to be sub-par, and that Roland picked out the problem areas quickly. That is what most Sav-On customers describe — the owner himself at the house, working out what is actually wrong.

Sav-On Insulation works out of 12 Lexington Avenue in Londonderry, New Hampshire. Its BBB profile names Roland Martin as owner and puts the business at 34 years, started in 1992. The work is insulation in its usual forms — batt, rolled and reflective, blown-in, spray foam and injection — plus soundproofing, and BBB also lists insulation removal. HomeAdvisor says the company serves Massachusetts and New Hampshire and offers emergency service; Angi lists free estimates and se habla español.

Speed comes up in more than half the reviews. In a March 2026 Angi review a homeowner said Roland called the same day the inquiry went in and was at the house that afternoon. An October 2024 customer getting ready for a zero-clearance wood stove insert said he called right back and showed up on time, and a November 2023 attic job drew the same note — at the house very quickly, prices the reviewer called fair.

The other thing customers mention is being told what they don't need. A 2022 HomeAdvisor reviewer described him going through both the things they needed and the things they didn't, and called him "a straight shooter without any of the sales frills". A 2023 HomeAdvisor reviewer who has owned three homes and renovated two said they had dealt with many contractors and put Roland near the top. Three reviews mention a second man on the job — named Brett in that 2023 account.

All eleven ratings — seven on Angi, four on HomeAdvisor — are five stars, spanning 2018 to March 2026.

Sav-On is a straightforward call for a specific insulation problem: a cold attic, recurring ice dams, clearance for a wood stove insert. Ask which type of insulation he is recommending and why, and get the scope and price in writing before the work starts.

**Strengths:**
- Fast response — same-day calls and quick scheduling described by reviewers
- Owner on site — Roland Martin named in nine of eleven reviews
- Plain advice — a 2022 reviewer cited no sales frills
- Ice dam diagnosis — 2018 reviewer credited him with finding sub-par insulation
- Full insulation range — spray foam, blown-in, batt and soundproofing
