# Sav-On Insulation LLC **Trade:** Insulation & Weatherization · **Languages:** English, Spanish **Rating: 3.5/5** (medium confidence) — from 7 reviews across 3 sources. 100% of sentiment-scored reviews read net-positive. Last 6 months: 0 reviews, 0 negative. ## The honest read Roland Martin picks up the phone himself, and in the write-ups that is half the story. A homeowner writing in March 2026 said he called the same day the inquiry went in, came to the house that afternoon and got right to work. An October 2024 customer said much the same: a call back right away, and the job on the schedule quickly. Sav-On Insulation is his company, working out of Londonderry, New Hampshire, and insulation is the whole of it — batts and rolled or reflective, blown-in, spray foam, injection, with soundproofing on the service list. Attics come up: in a November 2023 review, a homeowner said he knew what hers needed, was at the house quickly and charged a fair price, and that she would book him again for a second attic if she had one. The October 2024 job was insulation put in to prepare for a zero-clearance wood stove insert. He often works with a partner. A January 2024 customer said Roland explained what he was going to do and the two of them carried the plan out quickly; a November 2023 reviewer described the pair as personable and taking pride in the work. Seven reviews make up the written history, a 5.0 average, and the same seven appear on both Angi and HomeAdvisor — one profile carried on two sites. Each one names Roland. One thing to pin down: how long he has been at this depends on where you read. The Angi profile's highlights say 53 years of experience while its about text says over 40. For an attic, a blown-in top-up or the prep before a wood stove insert around Londonderry, this is a two-man operation whose customers describe quick scheduling and fair prices. Ask what depth and R-value the quote covers, and get the number in writing while he is at the house. **Strengths:** - Same-day response — call returned and on site the afternoon of the inquiry - Attic insulation — a 2023 customer said he knew what hers needed - Fair pricing — three reviewers called it fair, affordable or reasonable - Explains the plan — a 2024 customer was walked through the work first - Wood stove prep — insulation installed for a zero-clearance insert, 2024 **Where sources disagree:** - The Angi profile is inconsistent about experience: its business highlights state 53 years while the about text says over 40. ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - Seven reviews and a 5.0 average — the same seven carried on both Angi and HomeAdvisor _(confidence: high)_ - [Angi](https://www.angi.com/companylist/us/nh/londonderry/savon-insulation-llc-reviews-1.htm) — “Angi: 5.0★ from 7 ratings” - [Angi](https://www.angi.com/companylist/us/nh/londonderry/savon-insulation-llc-reviews-1.htm) — “Angi star distribution: 100% 5★ (of 7 ratings)” - [HomeAdvisor](https://www.homeadvisor.com/rated.SavOnInsulation.133730195.html) — “HomeAdvisor: 5.0★ from 7 ratings” - [HomeAdvisor](https://www.homeadvisor.com/rated.SavOnInsulation.133730195.html) — “Genuine HomeAdvisor profile for Sav-On Insulation LLC, Londonderry NH -- byte-identical mirror of the Angi profile (same 7 reviews, same 5.0…” - Owner Roland Martin runs Sav-On Insulation out of Londonderry, New Hampshire _(confidence: high)_ - [Angi](https://www.angi.com/companylist/us/nh/londonderry/savon-insulation-llc-reviews-1.htm) — “Genuine Angi profile for Sav-On Insulation LLC, Londonderry NH, run by owner Roland Martin -- 5.0/5 from 7 reviews, all naming Roland by nam…” - [HomeAdvisor](https://www.homeadvisor.com/rated.SavOnInsulation.133730195.html) — “Genuine HomeAdvisor profile for Sav-On Insulation LLC, Londonderry NH -- byte-identical mirror of the Angi profile (same 7 reviews, same 5.0…” - Insulation across the board: batts and rolled or reflective, blown-in, spray foam and injection installation, plus soundproofing _(confidence: high)_ - [Angi](https://www.angi.com/companylist/us/nh/londonderry/savon-insulation-llc-reviews-1.htm) — “Services offered (Angi): Batt, Rolled or Reflective Insulation Install or Upgrade, Blown In Insulation Install or Upgrade, Soundproofing Ser…” - [HomeAdvisor](https://www.homeadvisor.com/rated.SavOnInsulation.133730195.html) — “Services offered (HomeAdvisor): Batt, Rolled or Reflective Insulation Install or Upgrade, Blown In Insulation Install or Upgrade, Soundproof…” - A March 2026 customer said Roland called the same day the inquiry went in, came that afternoon and got right to work _(confidence: medium)_ - [Angi](https://www.angi.com/companylist/us/nh/londonderry/savon-insulation-llc-reviews-1.htm) — “5★ It was an absolute pleasure having Roland do my insulation job.
