Frequently asked questions
How should I choose a mold remediation company in Boston?
Start by checking Google reviews, but also verify licensing, insurance and professional affiliations. Ask for a written inspection report, a clear scope of work, containment and air-quality testing plans, and references from recent customers before committing.
When should I call a remediation or restoration service?
Call a professional when you see visible mold growth larger than a small patch, experience recurring dampness or water damage, or have health symptoms that may be linked to mold. Immediate response is also wise after significant leaks or flooding to limit spread and structural damage.
What should I check in a written estimate or contract?
Look for a detailed scope that separates inspection, containment, removal, cleaning, drying and post-remediation verification. The estimate should specify materials to be removed, clearance testing (if any), timelines, cleanup procedures and terms for additional discoveries.
