What affects homes here
- Historic village houses. Stone or brick foundations, shallow cellars, original attic framing.
- Mid-century suburban houses. Often finished basements and older bath fans.
- Newer subdivisions. Built tight. They hold moisture unless ventilation works.
Common problems
- Musty smell in a finished basement: basement mold removal.
- Black spots on attic roof boards: attic mold removal.
- Stains after a hidden leak: mold removal after water damage.
- Dark growth that worries you: black mold removal.
Year-round checklist
- Late winter: look in the attic for frost and stains.
- Spring: check the basement and sump after snowmelt.
- Summer: keep humidity under 60 percent (EPA).
- Fall: clear gutters. Check fans and dryer vent go outdoors.
What to do next
Note where it is, how big and the water history. Ask for references and a written scope, and how the moisture will be fixed. Check registration on Mass.gov. See the mold removal cost guide.

Frequently asked questions
Are older Westford houses more likely to have mold?
Often, from leakier foundations and attics. Newer houses trap humidity. What matters is a moisture source: a leak, damp soil or poor ventilation.
My finished basement smells musty. Is mold behind the drywall?
Possibly. A pro can check with a moisture meter or thermal camera. Cutting in without containment can spread growth.
What causes black spots on my attic roof boards?
Usually warm, damp air from the house freezing on the cold roof in winter. Sometimes an ice dam or roof leak.
Should I test my Westford home?
Usually not if the mold is visible (EPA, CDC, DPH). It can help for hidden mold or to verify cleanup.
