Good to know
HVAC & Air Duct Mold Remediation in Delavan Lake, WI: 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 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 Delavan Lake home.
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.
Do I need to leave my Delavan Lake home during the work?
Usually no. We seal the work area under negative air, so most of the Delavan Lake home stays livable. For larger jobs we will tell you if it is better to step out for a day.
Do you serve Delavan Lake?
Yes. We cover all of Delavan Lake, including Delavan, Fontana, Walworth, and the rest of the Delavan Lake area. We are based in Williams Bay, about 10 minutes from our Williams Bay base, and answer our own phone around the clock.
