Groundworks

Groundworks maintains a 4.9-star rating across 566 Google reviews, which matters in Manchester where homes built around 1965 face real moisture challenges. The area's 72% average humidity and 42 inches of annual rainfall create conditions where mold takes hold quickly in older structures. That track record suggests the company knows how to handle the specific problems Manchester homeowners encounter, and customer feedback at that level indicates consistent work quality you can rely on.

New Hampshire doesn't require a specific mold remediation license, so before hiring you'll want to verify that Groundworks is registered with the NH Office of Professional Licensure, carries IICRC certification, and maintains appropriate insurance coverage. Typical remediation projects in this area run between $1,500 and $4,650 depending on scope. Ask for references from recent local jobs and a detailed written estimate before committing, since mold damage can vary significantly from one home to another.
