Who offers soffit vent cleaning service, and do soffit vents need cleaning?
Short answer. Soffit vents occasionally need cleaning because pollen, dust, spider webs, wasp nests and paint can clog their small openings, and the people who usually do it are exterior cleaning and gutter cleaning services, handymen, and some roofing and gutter companies. Many homeowners can clean single-story soffit vents themselves with a soft brush and a vacuum.
Signs your soffit vents need attention
- Visible webs, nests or dust caked in the perforations.
- Louvers painted over during a house painting.
- Mildew darkening the soffit around the vents.
- An attic that runs hotter or stuffier than it used to.
Cleaning them yourself
- From a stable ladder, brush the perforations with a soft bristle brush.
- Vacuum loose debris with a brush attachment.
- Remove wasp or mud dauber nests carefully in the cool of the morning, or have a pest professional handle active nests.
- Wash mildew with a mild cleaner and a soft cloth, rinsing gently.
What not to do
- Do not blast vents with a pressure washer; it can drive water into the attic insulation and damage vinyl.
- Do not paint the vent openings shut.
- Do not seal vents to stop insects; repair or replace the screen instead.
Hiring it out
Soffit vent cleaning is often added to gutter cleaning or exterior soft washing. Ask how the vents will be cleaned and whether low pressure is used. If vents look clean but the attic still runs hot, the problem is likely inside, such as insulation blocking the eaves, which a cleaning service will not fix.
