Rodent Proofing for Seattle-Area Homes
Trapping gets rid of the rats you have. Proofing keeps the next ones out. We find the gaps rodents use, close them with steel and sealant, and protect the attic and crawl space they were living in.

Why Proof Instead of Just Trap
Removing rodents without closing the holes is a subscription to the same problem.
- Every entry point found and sealed
- Steel mesh and metal, not foam alone
- Protects new insulation from re-infestation

Everything You Need to Know About Rodent Proofing
Norway rats and roof rats are both common around Puget Sound, and both are excellent climbers. Rats get in through gaps about the size of a quarter, mice through gaps the width of a pencil. Typical entry points are torn foundation vent screens, gaps around pipes and cables where they enter the house, roof returns and eaves, plumbing vents, and the space where the garage door meets the slab.
We walk the outside of the house, go through the crawl space and attic, and mark every opening we find. Then we close them with galvanized hardware cloth, sheet metal, and sealant backed with steel wool or copper mesh. Spray foam alone doesn't stop a determined rat, so we don't rely on it.
If there's an active infestation, we combine proofing with trapping and come back until activity stops. If the attic or crawl space is contaminated, we clean it out and replace the insulation once the house is sealed.

Why the Puget Sound Has So Many Rats
Mild winters, plenty of rain and lots of vegetation mean rodents here don't face the hard freezes that thin out populations in colder places. Greenbelts, ravines, blackberry thickets, compost bins and backyard chickens all give them food and cover close to houses.
Roof rats in particular travel along fences, power lines and tree branches, which is why a rodent problem in the attic doesn't always start at ground level. We check rooflines and trim recommendations as part of the inspection.

Inspection
We find where rodents are getting in, where they're nesting, and how far the damage goes.
Removal
Traps go where the activity is, and we come back to check them until the activity stops.
Exclusion
Every entry point is closed with steel mesh, metal flashing or sealant that rodents can't chew through.
Cleanup
Droppings, nesting and soiled insulation come out, and the area is sanitized before new insulation goes in.
Often Done Together
Most projects involve more than one kind of work. These are the services homeowners most often pair with this one:

FAQ
How long does rodent proofing last? +
Properly sealed openings stay sealed. The main risk is new openings, like a contractor cutting a hole for a cable. We check our work on follow-up visits.
Do you use poison? +
We focus on trapping and exclusion. Poison can leave rodents dying inside walls, which creates an odor problem, so we use it sparingly if at all, and only where it's safe for kids and pets.
Will rodent proofing keep out other animals? +
The same work keeps out squirrels and birds in most cases. Larger animals like raccoons sometimes need heavier materials, which we'd quote separately.
Are you licensed and insured? +
Yes. Attic Star is licensed, bonded and insured in Washington (contractor license ATTICSI795QZ), and our own crews do the work. We don't use subcontractors.
How much will it cost? +
It depends on the size of the space and the work involved. The inspection is free, and you get a written quote before anything starts.
