Where rats get into Portland homes

The scratching in the walls usually starts when the rain does. These are the openings we check first.

  1. Foundation ventsRusted or torn vent screens on older crawlspaces
  2. Pipe and wire gapsWhere plumbing, gas and cable lines enter the house
  3. Crawlspace doorWarped access doors that no longer close flush
  4. Garage door cornersWorn bottom seals and gaps at the side tracks
  5. Roofline and attic ventsGaps under eaves where branches touch the roof

A rat can squeeze through a gap about the size of a quarter.

Three ways to seal out rats

Every job starts with an inspection. You choose how far to take it, and you get one fixed price before any work starts.

  • Inspect and seal

    Find every opening and close it.

Who shows up

Most rat problems in older Portland houses come back because nobody closed the openings. I'm building Groundtight to find and seal every one, and I'll do the first inspections myself.

Questions

Why aren't you booking yet?

We're finishing state licensing before we take any jobs. Joining the list holds your place in line.

What does sealing cost?

It depends on your home's size, foundation type and how many openings we find. You'll get a fixed price after the inspection, before any work starts.

Will you seal rats inside my house?

No. If we find signs of activity, we set traps and check them first, and close the last openings once activity stops.

Will you keep coming back?

Only if you want to. After sealing, you can add a quarterly check-up of your crawlspace and seals.

I need help today. What should I do?

We're not booking yet, so please call another provider for urgent problems. Joining the list costs nothing.
