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.

Our insurance claim went smoothly because their photos and paperwork were thorough. Honest people who did what they said they would do.

Our crawl space mold was worse than we thought. They handled the full remediation and installed a vapor barrier too.

Good to know

HVAC & Air Duct Mold Remediation in Leominster, 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.

Is the hvac & air duct mold remediation you do in Leominster to a real standard?

Yes. Our crew follows the IICRC S520 standard for mold remediation, the same framework insurers and inspectors recognize across Worcester County.

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 soon can you start hvac & air duct mold remediation in Leominster?

We answer our line 24/7 and can usually reach a Leominster home the same day you call, sooner for an active leak.

Do you serve Leominster?

Yes. We cover all of Leominster, including Fitchburg, Lunenburg, Shirley, and the rest of the Leominster area. We are based in West Boylston, about 20 minutes from our West Boylston base, and answer our own phone around the clock.
