Mold remediation companies in New Hampshire

Manchester, NH / 4.7 rating from 416 reviews / Water damage restoration service

Best for: Manchester-area homeowners dealing with water damage from burst pipes or basement flooding who want plumbing repair and mold remediation handled by a single crew on the same visit.

Service area: Headquartered at 862 S Porter Street in Manchester, New Hampshire. Covers Hillsborough, Belknap, Strafford, Rockingham, and Merrimack counties in New Hampshire, plus York County in Maine. Specific cities served include Goffstown, Bedford, Londonderry, Derry, Concord, Nashua, Merrimack, Dover, Rochester, Portsmouth, Laconia, and Saco. The territory is very large for a single location -- at least one reviewer was told their area was not actually serviced despite appearing on the coverage list.

Review snapshot: Pete, Leo, and Alan draw consistent praise for fast, friendly drain and plumbing work across dozens of reviews. But pricing is the recurring complaint -- multiple reviewers report $600-$980 charges for routine drain clearing, with 7 one-star reviews across 416 total at 4.7 stars.

Derry, NH / 5 rating from 286 reviews / Water damage restoration service

Best for: Southern New Hampshire homeowners dealing with attic mold, water damage, or radon who want a single family-owned firm with 35 years of experience and 24/7 emergency response.

Service area: Headquartered at 9 South Ave, Derry, NH. They serve Southern New Hampshire and claim broader New England coverage. Reviews confirm jobs in Derry, Londonderry, and surrounding towns. The 'New England' claim is broad, and response times will likely vary for locations far from Derry.

Review snapshot: Kevin, Ray, AJ, and Jack draw consistent praise across nearly every review for punctuality, clear communication, and clean job sites. But 1 of 286 reviews at 5.0 stars flags a driving safety concern with a company vehicle.

The 14-city footprint runs from Hampton Beach north to Rochester and west to Epping.

The territory extends north to Lancaster and North Stratford and south to Rumney. That covers roughly 100+ miles of northern New Hampshire. Reviewers confirm jobs in Haverhill, Claremont, Hartford (VT), Springfield, Guildhall, Derby Line, and Eastman, suggesting the actual service radius extends into Vermont and possibly southern Quebec border towns.

Review snapshot: Akim draws overwhelming praise across dozens of reviews for fast response, clear communication, and mold cleanup; Michelle, Kyle, Cody, and Ramon also get named repeatedly. But 6 one-star reviews across 132 total flag office rudeness (Debbie named), unauthorized charges, and drawn-out timelines on reconstruction projects.

The company states it typically services customers within a one-hour drive of Manchester.

Review snapshot: Seth, Tim Kearin, and Scott draw consistent praise for fast response and clear communication across 95 reviews. But the single 1-star review has no text, so no specific complaint to evaluate.

West Nottingham, NH / 4.9 rating from 88 reviews / Water damage restoration service

Best for: Strafford County homeowners dealing with water damage that has led to mold growth, where Tyson Bostrom's owner-operated franchise handles both cleanup and rebuild under one roof.

The service area spans roughly 80 miles from Laconia in the Lakes Region to Lowell MA, which may stretch the 60-minute response claim for outlying locations.

Review snapshot: Colby, Josh, and Nathan draw consistent praise for fast arrivals and clear communication across 84 reviews. But one reviewer noted repeated scheduling delays and crew cancellations during busy periods (0 one-star reviews across 84 total).
