Why exclusion is the real long-term fix

Eliminating pests without closing their entrances is bailing water without plugging the hole: every fall brings the mice back, every spring brings the wildlife. Buildings we fully secure almost never call us back for the same problem.

What our pest-proofing service includes

When to pest-proof

FAQ — Frequently asked questions

How is this different from a regular caulker?

A caulker works on water- and air-tightness. We work on pest exclusion: we know where animals get in, how they chew, and which materials resist them. A nice silicone bead won't stop a mouse or a squirrel.

Is it guaranteed?

Yes: our exclusion work is covered by our written guarantee. If a pest gets through a point we sealed, we come back and fix it free of charge.

How long does the work take?

For a typical home, inspection and proofing are done in half a day to a day, depending on the number of points. You get the exact scope with your estimate.
