Mice exclusion and sealing — also called rodent exclusion and proofing — closes the openings mice use to enter your home. A mouse can fit through a gap the size of a dime, so the work covers foundation cracks, gaps around pipes and wires, vent openings, rooflines, and the spaces under doors. Sealing is what turns a one-time removal into a lasting result.
The work uses materials mice cannot chew through easily, such as metal mesh, sealant, and door sweeps, fitted to each opening. Rodent attic cleanup and exclusion often go together: once droppings and nesting material are cleared from an attic, sealing the attic entry points keeps the space clean. Exclusion is planned around your home's construction, so an older Olympia house with many small gaps gets a different scope than a newer home with a few pipe penetrations.
What mice exclusion & sealing includes
- A survey of entry points around the foundation, roofline, vents, and doors
- Sealing of gaps around pipes, wires, and utility penetrations
- Metal mesh and sealant fitted to openings mice can chew through
- Door sweeps and vent covers where mice are entering
- Sealing of attic and crawl space access points
How it works
Call (360) 812-9464 and describe the problem. We connect you with a local Olympia provider.
The provider maps every entry point, from foundation cracks to rooflines and pipe gaps.
Openings are sealed with mesh, sealant, and sweeps matched to each gap.
The provider reviews the sealed points with you and notes anything to watch, such as new gaps from settling or repairs.
Mice Exclusion & Sealing in Olympia
Olympia's older housing stock is the main reason exclusion matters here. Homes in South Capitol and the Eastside, many built decades ago, have settled foundations, older rooflines, and utility penetrations that have opened over time. The wet climate also keeps wood and sealants aging, so gaps that were closed years ago can reopen. A thorough sealing job on an older Olympia home usually covers more points than the same job on a newer West Olympia subdivision home — and that difference is normal.
The entry points Olympia homes hide
The gaps mice use are rarely obvious. Foundation cracks open as houses settle, rooflines shift where flashing and fascia meet, vent covers loosen in wet winters, garage doors stop sealing at the corners, and pipe and wire penetrations leave small rings of space where they pass through siding and foundation. Each gap alone looks harmless; together they give mice several ways in, which is why a survey maps all of them instead of fixing the first gap found.
Older Olympia homes usually hide more of these than newer ones. A South Capitol or Eastside home may need foundation, roofline, vent, and utility work across the whole exterior, while a newer West Olympia subdivision home may need only a few pipe gaps and a door sweep. Sealing uses metal mesh, sealant, door sweeps, and vent covers matched to each opening, because a material that works on a pipe gap may not suit a roofline joint.

Mice Exclusion & Sealing questions, answered
What is mice exclusion and sealing?
Mice exclusion and sealing, also called rodent proofing, means closing the gaps mice use to enter a home — foundation cracks, pipe and wire gaps, vent openings, rooflines, and spaces under doors — using mesh, sealant, and sweeps.
Does sealing alone get rid of mice?
Sealing keeps new mice out, but mice already inside still need removal first. The usual order is removal, then sealing, so the mice inside are dealt with and new ones cannot replace them.
What materials are used for exclusion?
Providers use materials mice cannot easily chew through, such as metal mesh and sealant, plus door sweeps and vent covers. The material is matched to each opening, from a pipe gap to a roofline joint.
How long does exclusion last?
It depends on the home. Sealing lasts longer on stable, newer construction and may need touch-ups on older homes as foundations settle and materials age. Your provider can note which points to watch over time.
Is exclusion worth it for an older Olympia home?
Older homes usually benefit the most, because they tend to have the most entry points. A full survey finds gaps that are easy to miss, including rooflines and utility penetrations, and sealing them is what keeps a removal result from being temporary.
