Provider snapshot
What this listing says
Southeastern New Hampshire homeowners dealing with mold or water damage who want a multi-office restoration company with IICRC and ACAC credentials and a separate construction arm for rebuild work.
Best for
- Southeastern NH homeowners with mold or water damage who want a company that can handle both remediation and reconstruction through its sister firm.
- Property owners facing asbestos or lead issues alongside mold — Octagon handles all three under one contract.
- Condo associations and commercial properties needing duct cleaning or large-scale water extraction on short notice.
- Buyers who want a company that openly declines post-remediation testing to avoid conflict of interest.
About this company
Octagon Cleaning and Restoration is a locally owned restoration company based in Barrington, NH, with a second New Hampshire office in Meredith and three more in Maine. Their primary identity is disaster restoration — water damage, fire and smoke, mold removal — but they also handle asbestos abatement, lead removal, biohazard cleanup, storm damage, and commercial duct cleaning. They hold IICRC and ACAC credentials and are an EPA Lead-Safe firm.
What stands out is the breadth of hazmat work under one roof. Asbestos and lead removal are uncommon add-ons for a mold remediation company, and they carry the state-specific licensing those services require in New Hampshire and Maine. They also have a sister company, Octagon Construction, that handles the rebuild side — meaning a single call can take a project from water extraction through drywall replacement. Their FAQ explicitly states they do not perform post-remediation mold testing, recommending independent third-party testing instead.
The company operates five offices across two states, which gives them geographic reach but also means the crew that shows up in Barrington may differ from the one in Brewer, Maine. They are a member of the Greater Barrington Chamber of Commerce and advertise 24/7 emergency response.
With 64 Google reviews and a 4.7-star rating, they sit in strong territory. Nearly every review with text is 5 stars, and the only recent negative has nothing to do with the quality of their restoration work.

Review consensus
Michelle appears in more reviews than any other employee, praised for mold remediation, water extraction, and detail-oriented work. Amber is the second most-mentioned name, credited with fast water damage response and clear communication. Chris drew praise for explaining each step during water extraction. Jason was noted for designing cleanup plans and staying involved throughout projects. Tony Comeau was specifically called out for knowledgeable mold inspections without pressure to sell. Multiple reviewers highlight same-day or next-day emergency response, clean jobsites after completion, and transparent pricing.
1 found across 64 total reviews at 4.7★. The single recent 1-star review describes a company truck pulling in front of a school bus at speed. It is not a service complaint — no work was performed for this reviewer. The owner responded within a day saying they would look into it. As a driving incident rather than a service failure, this tells you nothing about the quality of their restoration work.
The review base is unusually clean. Sixty-three of 64 reviews are 4 or 5 stars, and the lone 1-star is a traffic complaint, not a service issue. One 4-star reviewer (Sarah Cantara) noted the job took double the estimated time, though the company reimbursed her for the inconvenience through Maddie Coro. This is a company where the main risk is logistical — crew scheduling across five offices — rather than workmanship.

This is a well-reviewed restoration company with a deep bench of named technicians. Ask for Michelle or Amber if your job involves mold or water damage — they appear in the most reviews. Get your initial mold assessment from an independent inspector so the scope of work is unbiased, then let Octagon handle the remediation and any rebuild through their construction arm.
Keep in mind
- They do both mold inspection and remediation. They acknowledge the conflict of interest in their FAQ and recommend third-party post-remediation testing, but you should still get your initial inspection from an independent assessor if you want an unbiased scope of work.
- Five offices across two states means your crew could be dispatched from any location. Ask which office and which team will handle your project.
- Their claimed service area covers six New Hampshire counties and well over 100 towns. Confirm response time for your specific town before signing.
- They were not the cheapest option according to one reviewer who still chose them for responsiveness. Get competing bids.
