Professional Attic Cleaning You Can Trust

An attic is the one part of your home you almost never see, which is exactly why it becomes a problem. Dust, insulation fibers, construction debris, bird nesting and rodent droppings build up over years, and everything that accumulates up there eventually cycles down into the air your family breathes through ceiling penetrations, recessed lights and HVAC returns.

AttiCal has cleaned attics across the Bay Area since 2011 as a licensed contractor (Attical Inc. # 1126472). Our in-house inspectors — not salespeople — evaluate the attic first and give you a written report with photos, so you know exactly what is up there before you spend a dollar.

Most residential attic cleanings are finished in a single day. Light dust and debris removal typically runs 4–6 hours, moderate cleanouts 6–12 hours, and larger jobs involving full insulation removal and sanitizing may take one to two days.

Signs your attic needs a professional cleaning

  • Droppings, urine staining or a musty ammonia smell coming from the ceiling
  • Scratching or scurrying noises overhead at night
  • Dust, insulation fibers or debris falling from recessed lights and vents
  • Allergy or asthma symptoms that get worse indoors
  • Insulation that is flattened, discolored, wet or displaced
  • You recently bought the home and have never seen the attic

What an AttiCal attic cleaning includes

Debris and contamination removal

Droppings, nesting material, old vent boots, construction debris and contaminated insulation are bagged at the source and carried out through protected walkways.

HEPA vacuuming

Framing, joist bays and the attic floor are HEPA vacuumed to capture fine particulate the naked eye never sees.

Sanitizing and deodorizing

Affected surfaces are treated with a professional-grade disinfectant to neutralize odor and the bacteria left behind by pests.

Containment and cleanup

Floor protection, sealed bagging and full jobsite cleanup. Uniformed technicians leave the living space cleaner than they found it.

Attic Cleaning FAQs

Most attic cleanings take between 4 hours and 2 days. Light dust and debris removal usually takes 4–6 hours, moderate cleanouts 6–12 hours, and extensive projects involving insulation removal or pest sanitization may take 1–2 days.

In most cases no. We contain the work area and protect walkways so you can stay home. If heavy sanitizing is involved we will tell you in advance whether a few hours away is recommended.

Cleaning always comes first. Installing new insulation over contaminated material traps odor and bacteria and wastes the value of the new insulation.

Yes. The attic and crawl space inspection and the written report cost nothing and carry no obligation.
