Common signs

Signs your crawl space insulation needs replacing

  • Insulation hanging down

    Batts sagging out of the joists or lying on the ground.

  • Wet, matted or stained

    Insulation that's heavy, flattened or discolored from moisture.

  • Missing sections

    Gaps between joists where insulation has fallen or was never installed.

  • Cold floors

    Floors that feel noticeably cold in winter can point to missing or failed insulation below.

  • Torn up by pests or past work

    Insulation pulled apart, nested in or left disturbed after other repairs.

Insulation usually fails because of moisture. We look for the cause before replacing it.

Why crawl space insulation matters

In a vented crawl space, insulation between the floor joists helps separate your living space from the cold, damp air below. When it falls down, gets wet or goes missing, it stops doing that job.

We remove damaged insulation, check for the moisture that caused the problem, and install new insulation fit to your floor framing. If your crawl space is being encapsulated, we'll explain how insulation fits into that plan, since the approach can be different.

  • Remove old, fallen or wet insulation
  • Install new insulation between the floor joists
  • Secure it so it stays in place
  • Flag moisture issues that could damage it again

Often done with a cleanout

Insulation replacement usually goes hand in hand with a crawl space cleanout. Old batts, debris and worn-out plastic come out together, and a new vapor barrier below keeps your new insulation dry for years to come.

Questions

Crawl Space Insulation questions

Why does crawl space insulation fall down?

Moisture is the most common cause. Damp air makes fiberglass heavy until it sags out of the joists. Poor fastening, pests and past work under the house can also pull it down. We fix the cause and install insulation that stays put.

Do you remove the old insulation?

Yes. Damaged or fallen insulation comes out before new insulation goes in, and removal is included in your estimate.

What type of insulation do you use?

We choose the right insulation for your crawl space and floor framing, and we'll walk you through it during your estimate.

Will new insulation lower my energy bills?

New insulation keeps the heat in your home from escaping through the floor, so your heating system doesn't have to work as hard. Homeowners notice warmer floors and a more comfortable home, especially when the old insulation was missing, wet or falling down.

Should I insulate if my crawl space is damp?

We check for moisture during every inspection. If we find any, we take care of it first so your new insulation lasts.

How do I get an estimate?

Getting started is easy. Call or text (360) 470-4956, or fill out the form on this page. We'll learn what's going on beneath your home, schedule a time to take a look, and give you a straightforward insulation estimate.

I feel very happy and pleased with the work Jon did under my house. He cleaned up the entire crawl space!! Jon is hard working and I would recommend him highly.
