Why Kent Homes Need Rodent Proofing
Kent's industrial valley floor - with its food-distribution warehouses, restaurant supply businesses, and agricultural remnants - supports one of the highest Norway rat populations in King County. As winter flooding raises the water table along the Green River corridor, rat colonies migrate uphill into residential neighborhoods, targeting the warm crawl spaces and attics of valley-floor ramblers. The large flat soffits common on 1950s Kent ramblers are especially vulnerable, as are the wide gaps around utility conduits that pre-code homes never had sealed. Once inside, rats can destroy a full attic's worth of blown-in insulation - and the urine they leave behind creates serious indoor air quality hazards.
Our rodent proofing process
Every rodent proofing project in Kent follows the same structured process.
Free Inspection
We inspect the attic, crawl space, roofline, and foundation for entry points, droppings, nesting, and insulation damage. Documented with photos.
We identify species during the inspection. Valley-floor Kent neighborhoods see mostly Norway rats, while East Hill and Meridian trend toward roof rats.
Written Estimate
Line-item pricing for exclusion, cleanup, and any insulation replacement. No pressure, no surprises.
Exclusion & Sealing
Every entry point sealed with metal mesh, caulk, or sheet metal. Gaps around pipes, vents, soffit joints, and foundation cracks closed permanently.
Kent homes near the industrial corridor often have heavier populations, so we monitor traps longer before sealing to make sure active colonies are cleared out.
Contamination Cleanup
Droppings, nesting material, and contaminated insulation removed. Surfaces sanitized with antimicrobial solution.
The wide eave gaps on 1950s Scenic Hill ramblers and the utility penetrations on East Hill two-stories each need different exclusion materials and techniques.
Re-Insulation
New blown-in insulation installed to R-49 code if old insulation was removed due to contamination.
Follow-Up
We check back to confirm no new activity. Warranty covers re-entry through sealed points.
What's Included
Rodent Proofing Scope of Work
Full Exclusion
Every entry point from foundation to roofline sealed with durable materials
Contamination Cleanup
Droppings, nesting, and damaged insulation removed and disposed of properly
Sanitization
Antimicrobial treatment of affected areas after cleanup
Re-Insulation

Green River Corridor Pressure Assessment
Homes near the industrial valley and Green River face ongoing rodent migration pressure. We map the exterior entry points most vulnerable to re-entry from adjacent agricultural and warehouse habitat so your exclusion plan accounts for Kent-specific pressure patterns.

Rats and mice thrive in Kent's Green River Valley, where agricultural land, commercial warehouses, and dense residential neighborhoods sit side by side. Homes in Scenic Hill and downtown Kent - particularly the 1950s ramblers with wide eave gaps and unscreened foundation vents - serve as prime overwintering habitat for Norway rats moving up from the valley floor as winter rains arrive. East Hill subdivisions from the 1980s and 1990s are not immune: Panther Lake and Meridian homes frequently report roof rats exploiting aging roof-to-wall intersections and utility penetrations.
Green Attic's rodent-proofing service starts with a comprehensive entry-point audit, identifying every gap larger than a quarter inch. We then seal permanently using galvanized hardware cloth, copper mesh, and exterior-grade sealant - not the foam plugs that rodents chew through in days. Any insulation contaminated with droppings or urine is removed and replaced as part of a full attic or crawl space restoration.
Projects range from $800 for targeted exclusion sealing to $5,000 for whole-attic cleanup, insulation replacement, and sanitization. We stand behind our exclusion work with a one-year re-entry guarantee: if rodents find a new way in through any area we sealed, we return at no charge.
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.”

“Rats had been in our attic for months. Green Attic sealed every entry point, removed all the contaminated insulation, sanitized the space, and installed new blown-in. The whole project took two days. Our energy bill dropped $60 the next month.”
DDiana M.
Renton · Rodent Proofing + Attic Cleanup
“Squirrels had chewed through our soffit vents and nested in the insulation. Green Attic sealed every gap with steel mesh, pulled out the contaminated batts, and re-insulated the whole attic. No more scratching sounds at night.”

Rodent Proofing FAQ for Kent
Common questions from Kent homeowners about rodent proofing.
What rodent species are most common in Kent homes?
Norway rats are the dominant species on Kent's valley floor, particularly near the industrial corridor and Green River. Roof rats are common on East Hill and in Meridian, where mature tree canopies provide aerial access to rooflines. House mice are found throughout the city. Each species requires different exclusion strategies, which is why our initial inspection identifies species before we propose a scope.
How much does rodent proofing cost in Kent?
Exclusion-only sealing (no insulation work) runs $800-$2,000 depending on the number and complexity of entry points. If attic insulation has been contaminated and needs removal and replacement, total project costs typically run $2,500-$5,000. We provide a written estimate before any work begins.
Do you guarantee your rodent exclusion work in Kent?
Yes. We offer a one-year re-entry guarantee on all sealed entry points. If rodents breach any area we treated within twelve months, we return and re-treat at no additional cost. This guarantee covers materials and labor for any failure at a sealed penetration.
Is rodent-contaminated insulation dangerous?
Yes. Rodent droppings and urine carry hantavirus, leptospirosis, and salmonella, all of which can become airborne when contaminated insulation is disturbed. We use full PPE and HEPA vacuums during removal and apply EPA-registered disinfectant to all affected surfaces before installing fresh insulation.

"The Norway rat pressure along the Green River corridor is real. We seal every gap with galvanized steel, not foam, because rats chew through foam in a day. Once the house is sealed properly, the problem is solved for good."
