Can a clogged dryer vent cause a fire in Rockville, MD?

Yes, lint buildup in your dryer vent is a serious fire hazard and should be cleaned regularly. We recommend cleaning your vent at least once a year to stay safe.

Signs include visible dust around vents, musty smells, or higher energy bills. We can inspect your system and let you know if cleaning will help.
