We noticed the musty smell was worse whenever the furnace kicked on. Turned out there was mold growing in a duct section running through the crawl space. The team cleaned it and helped us figure out where the moisture was coming from.

Good to know
HVAC & Air Duct Mold Remediation in Waltham, MA: common questions
How do I know if my ductwork has mold?
A musty smell that gets stronger when the HVAC system runs, or visible growth around vent covers, are the most common signs.
Will you fix the moisture causing the mold?
We identify the moisture source, whether it's condensation, a crawl space leak, or humidity issues, and either address it directly or coordinate with an HVAC technician.
Do I need to replace ductwork with mold in it?
It depends on the material and extent of growth. Metal ductwork can often be cleaned, while some flexible or fiberglass-lined duct may need replacement.
How soon can you start hvac & air duct mold remediation in Waltham?
We answer our line 24/7 and can usually reach a Waltham home the same day you call, sooner for an active leak.
Can I clean duct mold myself?
Ductwork is hard to access safely and cleaning it without proper containment can push spores through the whole house, so it's best left to a professional crew.
Does a humidifier make duct mold more likely?
It can, since evaporative coolers add significant humidity to the air moving through the ductwork, especially if the system isn't well maintained.
How do you keep the mold from coming back after hvac & air duct mold remediation?
We fix the moisture source first, not just the mold, then dry the structure and recheck it. That is what keeps mold from returning to a Waltham home.
Do you serve Waltham?
Yes. We cover all of Waltham, including Bemis, West Newton, Nonantum, and the rest of the Waltham area. We are based in Auburndale, about 5 minutes from our Auburndale base, and answer our own phone around the clock.
