Attic and Crawl Space Cleaning
Attic and Crawl Space Cleaning Services in the Bay Area
Contaminated attics and crawl spaces are not just an odor problem. Rodent waste, decomposed insulation, and organic buildup affect air quality, accelerate structural damage, and create conditions that keep attracting animals. Lasting results usually pair cleanup with sealing rodent entry points. Rywen removes the material, treats affected surfaces, and installs clean insulation so the problem does not return.

What Homeowners Experience
When the Space Above or Below Your Home Needs More Than a Quick Fix
Most homeowners do not check their attic or crawl space until something becomes noticeable. By the time odors or damage are obvious from inside the house, the cleanup needed below is usually significant. These are the situations we encounter most often:
- Persistent odor that does not improve with airing out or cleaning inside the house
- Visible droppings, nesting material, or urine staining throughout the attic or crawl space
- Insulation that is heavily compressed, soiled, or has broken down from moisture and contamination
- Old or deteriorated blown-in insulation that has settled below minimum R-value over the years
- A previous rodent proofing job where contaminated insulation was never removed
- Crawl space debris including old vapor barrier remnants, wood scraps, or organic buildup
The Rywen Approach
Full Removal, Decontamination, and Clean Reinstallation
A cleaning job done correctly removes the source of the problem, not just the visible surface. Rywen uses commercial vacuum equipment with HEPA filtration for blown-in insulation removal, treats exposed wood and framing, and installs new material only after the space is confirmed clean and dry. In damp crawl spaces, cleaning is often the first step before encapsulation.
- Free inspection with documentation of contamination level, insulation condition, and moisture status
- Safe removal of blown-in insulation using HEPA-filtered commercial vacuum equipment
- Removal of fiberglass batt, nesting material, and debris by hand where necessary
- Decontamination and disinfection of affected wood surfaces - joists, rafters, subfloor, and sheathing
- Removal of old or damaged vapor barrier from crawl space floor
- Final cleaning of the space before new materials are installed
- New insulation installation and follow-up inspection before warranty is issued
How It Works
How the Cleaning Process Works
step 1
Free Inspection
We assess the full extent of contamination, document what we find with photos, and measure insulation levels. You receive a written report with a clear explanation of what needs to be done and why.
step 2
Written Estimate
Same-day pricing covering removal, decontamination, and new insulation installation. We break down each component so you know exactly what you are paying for.
step 3
Removal
Commercial vacuum equipment removes blown-in insulation safely. Batt insulation and debris are removed by hand where needed. Living areas are protected during the process.
step 4
Decontamination
Affected framing surfaces are treated with appropriate disinfectant products. Heavily stained or damaged areas are documented and photographed for the project record.
step 5
New Insulation and Vapor Barrier
Fresh insulation is installed to current R-value standards. In crawl spaces, a new vapor barrier is installed as part of the same project if the liner was removed.
STEP 6
Follow-Up and Warranty
We return after installation to verify conditions before issuing your warranty. If the cleaning was paired with rodent proofing, the follow-up confirms exclusion work is also holding.
Common Questions
Attic and Crawl Space Cleaning - What Homeowners Ask
How do I know if my attic or crawl space needs to be cleaned?
The most reliable indicator is having it inspected. A persistent odor in the house with no identifiable indoor source, a history of rodent activity, or insulation that has not been replaced in 20+ years are all good reasons to schedule an inspection. We document what we find and let you decide how to proceed.
Is the odor removed after cleaning?
In most cases, yes. The odor source is typically decomposing organic material – droppings, urine, nesting debris, or contaminated insulation. Removing the material and treating the affected surfaces eliminates the source. Odors that have permeated HVAC ductwork may require separate attention.
Do you need to do rodent proofing at the same time as cleaning?
Not necessarily, but it is often recommended. If the contamination was caused by animal activity, cleaning without sealing entry points means the space will likely become contaminated again. We discuss this honestly during the inspection and let you decide how to proceed.
How is contaminated insulation removed safely?
Blown-in cellulose and fiberglass are removed using commercial vacuum equipment with HEPA filtration to prevent airborne particulate from spreading through the house. Batt insulation is bagged and removed by hand. Our crew uses appropriate protective equipment throughout the process.
How long does an attic cleaning take?
Most attic cleaning projects are completed in one day. Larger homes or spaces with significant contamination may require two visits. Crawl space cleaning timelines depend on the size of the space and the condition of the existing vapor barrier.
