Not every moisture problem is a flood. Condensation on ductwork, musty smells that come and go, and stains that show up months later are signs of humidity and ventilation problems that quietly damage a house. We find the source and control it.

Signs you need attic & crawl moisture control

Musty smell in humid months
Sweating ducts or pipes
Rusting nails or dark staining on roof sheathing in the attic
Peeling paint or stained ceilings with no obvious leak
Indoor humidity that stays above 55 percent

How we do it

Readings
Humidity, temperature and moisture readings in the attic, crawl space and living space tell us where moisture is coming from and where it is condensing.
Vapor control
Ground vapor barrier in the crawl space and air sealing where warm, moist air is leaking into cold spaces.
Ventilation
Correcting blocked soffits, bath fans that vent into the attic and other ventilation mistakes.
Dehumidification
A dedicated dehumidifier for the crawl space or basement with automatic drainage.

Common questions

Why does my house smell musty only in summer?

Warm, humid outdoor air entering a cool crawl space or basement condenses and feeds mold. Controlling humidity fixes the smell.

Do I need a dehumidifier if I encapsulate?

Usually yes. The liner stops ground moisture, and the dehumidifier handles humidity that is already in the air.

Can you fix attic condensation?

Yes. It is usually a combination of air sealing the ceiling, fixing exhaust fans and restoring ventilation.
