Rodent Proofing & Exclusion in King & Snohomish County

Most residential rodent proofing projects in King County and Snohomish County fall between $1,500 and $6,000. The final price depends on the size of your home, the number of entry points, and whether you need insulation replacement or sanitation work. We provide a written estimate with line items before any work begins.

The most common signs are scratching or scurrying noises at night, droppings along walls or in the attic, chewed wiring or insulation, grease marks along baseboards, and a stale or musty smell that will not go away. If you are noticing any of these, call us for a free inspection and we will tell you exactly what is going on.

We handle both. Our process includes trapping and removal of active rodents as well as full exclusion to seal every entry point. We do not just set traps and hope for the best. We make sure the animals are out and then make sure they cannot get back in.

In most cases, yes. Rodent-contaminated insulation is a health hazard. Droppings, urine, and nesting material break down the insulation and reduce its R-value. We remove the contaminated material, sanitize the space, and install new blown-in insulation to the current R-49 code standard.

A typical home takes 1 to 3 days depending on the number of entry points and whether insulation replacement is included. Smaller jobs with just exclusion work can sometimes be completed in a single day. We give you a clear timeline during the estimate.

We warranty our exclusion work. If rodents re-enter through any entry point we sealed, we come back and fix it at no additional charge. No exclusion company can guarantee that a rodent will never chew a new hole somewhere, but we seal every vulnerable point and use materials that rodents cannot easily penetrate.

We use galvanized steel mesh, metal flashing, steel wool, commercial-grade sealant, and hardware cloth depending on the location and size of the gap. We do not use expanding foam alone because rodents can chew through it. Every seal is backed by metal or steel mesh.

Yes. Rodents chew on electrical wiring, and exposed or damaged wiring is a documented fire hazard. The National Fire Protection Association estimates that rodent damage to wiring causes thousands of house fires each year. If you have rodents, getting them out and inspecting your wiring is important.

It is. Rodent droppings and urine can carry hantavirus, salmonella, and other pathogens. When contaminated insulation is disturbed, these particles become airborne and can enter your living space through gaps in the ceiling or ductwork. Professional cleanup with proper containment is the safe way to handle it.

Yes. Rodents access homes from above and below. We inspect and seal both attics and crawl spaces as part of every rodent proofing project. If your crawl space needs additional work like vapor barrier installation or moisture control, we handle that too.

Pest control typically focuses on trapping or baiting to reduce the rodent population. Rodent proofing, also called exclusion, focuses on sealing the building so rodents cannot get inside in the first place. We do both, but the exclusion work is what provides the long-term solution.

Yes. Every project starts with a free on-site inspection. We check your attic, crawl space, roofline, and foundation for entry points and signs of activity. You get a written report and estimate with no obligation.
