Attic Cleanup in Kent, WA - Full Removal, Sanitization & Re-Insulation

Why Kent Homes Need Attic Cleanup
Kent's damp valley climate accelerates the degradation of attic insulation faster than in drier climates. Fiberglass batts that absorb moisture lose up to 40% of their rated R-value when wet - and in a valley-floor home on Scenic Hill or near downtown Kent, that moisture exposure is seasonal and recurring. Old blown-in vermiculite (sometimes present in pre-1980 Kent homes) can contain asbestos and requires licensed abatement. Combined with the high Norway rat population along the Green River corridor, Kent attics often require simultaneous pest remediation and full insulation replacement - a scope our team handles as a single coordinated project.
Our attic cleanup process
Every attic cleanup project in Kent follows the same structured process.
Free Inspection
We assess insulation condition, contamination level, rodent evidence, ventilation, and structural concerns. Everything documented with photos.
We photograph every condition we find so you can see what is happening up there before deciding on a scope.
Written Estimate
Line-item pricing for removal, cleanup, sanitization, and re-insulation. Transparent pricing -no change orders.
Insulation Removal
Old insulation vacuumed out using industrial extraction equipment. Bagged and hauled for proper disposal.
Valley-floor ramblers on Scenic Hill often have compressed rockwool or vermiculite that requires special handling. East Hill homes tend to have degraded fiberglass batts.
Sanitization
Attic surfaces HEPA-vacuumed and treated with antimicrobial solution to neutralize contaminants.
We HEPA-vacuum all structural surfaces and apply EPA-registered antimicrobial treatment, which is critical in Kent attics where high humidity promotes bacterial growth.
Air Sealing
Exposed penetrations, gaps, and cracks sealed before new insulation goes in.
New Insulation
Blown-in insulation installed to R-49 code specification with even coverage throughout the attic.

Puget Sound Energy Rebates for Kent Homeowners
Many insulation and weatherization upgrades qualify for rebates from Puget Sound Energy and federal tax credits. We handle the paperwork.
After years of moisture exposure, rodent activity, or simple age-related degradation, many Kent attics are in worse shape than their owners realize. On the valley floor, Scenic Hill and West Hill homes built in the 1950s often contain original fiberglass batts or even loose rockwool that has compressed to near-zero R-value and accumulated decades of dust, debris, and rodent droppings. East Hill homes from the 1980s fare slightly better but frequently have attics that were used for storage - leaving damaged insulation, abandoned HVAC ducts, and construction debris that needs professional removal before re-insulation can proceed.
Green Attic performs complete attic cleanouts using commercial HEPA vacuum equipment, removing all old insulation, sanitizing structural wood, and re-insulating to current R-49 code with blown-in cellulose or fiberglass. We also address air leakage at top-plates, recessed lights, and plumbing chases as part of every cleanup - boosting post-project performance significantly.
Attic cleanup costs in Kent typically run $3.50-$5.50 per square foot for removal, sanitization, and re-insulation. PSE customers can often stack rebates for insulation upgrades with the project, reducing net out-of-pocket cost.

What Kent Customers Say
“We found mold in our crawl space during a home inspection and didn’t know where to start. Sadeq’s team explained exactly what they’d do, how long it would take, and what it would cost. The clearance test came back clean. We closed on our house two weeks later.”

Attic Cleanup FAQ for Kent
Common questions from Kent homeowners about attic cleanup.
How do I know if my Kent attic insulation needs to be replaced vs. topped off?
If insulation is visibly compressed below 4 inches, shows water staining, or has rodent contamination, replacement is the right call. Topping off works well only when the existing material is clean, dry, and structurally intact. During our free inspection we measure current R-value and check for moisture and biological contamination before recommending a path forward.
What does attic cleanup cost in Kent, WA?
Removal and sanitization alone runs $1.50-$2.50 per square foot. Combined removal, sanitization, air sealing, and re-insulation to R-49 typically runs $3.50-$5.50 per square foot. A 1,200 sq ft Kent rambler attic averages $4,200-$6,600 for the full scope, before any applicable PSE rebates.
How long does a full attic cleanup and re-insulation take?
The majority of Kent homes are completed in a single day - crew arrives in the morning, removes the old material, air-seals the attic floor, and installs fresh blown-in insulation before end of day. Larger East Hill homes with high-volume attic spaces or significant debris may carry into a second day. We schedule removal and re-insulation as a continuous sequence so the attic is never left open overnight.
Can you handle vermiculite or other hazardous materials in older Kent attics?
We test for asbestos-containing vermiculite before any removal work on pre-1980 Kent homes. If asbestos is confirmed, we coordinate with a licensed abatement contractor before our insulation crew proceeds. We will not disturb suspect material without proper testing - it's both a legal requirement and a safety matter.

"A lot of the East Hill homes we clean out still have the original batt insulation from the 1980s, and it is usually full of rodent droppings and moisture damage. Once we pull all of that out and re-insulate to R-49, the difference in comfort is immediate."
