Mold Remediation — Boston, MA
Quick gut-check: if water is flowing where it shouldn't be, call. If it's just a slow drip, you can wait until morning at standard rates. Most of our work comes from neighbors of past customers. That's the only marketing we trust.
The actual work
Mold work follows IICRC S520 protocol: contain the area first to prevent spore spread, then remediate. Skipping containment is the #1 mistake unlicensed mold contractors make.
We set up plastic barrier walls around the affected area, run negative air pressure with HEPA-filtered air scrubbers (typically 4-6 air changes per hour), and the crew works in PPE inside the contained area.
Visible mold growth on porous materials (drywall, carpet, padding, fabric) is removed and bagged. Hard surfaces are HEPA-vacuumed and treated with EPA-registered antimicrobials.
After remediation, we run post-remediation verification (PRV) testing — usually third-party — to confirm the affected area returns to baseline.
How Boston jobs differ
Boston has a wide mix of housing — from pre-war brick to last-year new builds. We work on all of it; the diagnostic just takes a different shape.
That said, newer construction in Boston has its own set of typical issues. We see both.

A recent mold remediation call
Last spring we got a call from a homeowner near the west Boston. Black mold growing on drywall behind a wallpapered bathroom. Diagnosis: slow leak from a shower valve had been wetting the drywall for 18+ months. We S520 containment, removed all affected drywall and tile substrate, treated framing with antimicrobial, post-remediation verification testing passed, ran the test, and were out the door in before lunch. Total: $1812 including parts.
