The right fix starts with the right diagnosis

Insulate below grade without ignoring moisture

Insulation installed without accounting for moisture is one of the most common comeback jobs we see, batts that trap dampness against framing and stop performing within a year or two. We install insulation strategy alongside, not instead of, moisture control, so the R-value you pay for actually lasts.

Common problems we solve

  • Rim joist areas with no insulation, a major source of drafts
  • Existing insulation that is wet, sagging, or moldy
  • Cold floors or rooms above an uninsulated basement or crawl space
  • Insulation installed without first addressing an underlying moisture issue

Benefits of a properly designed solution

Moisture-aware materials

We select insulation types that will not absorb and hold ground or basement moisture.

Targets real energy-loss points

Rim joists and foundation walls are common, often-overlooked sources of heat loss.

Coordinated with moisture control

Insulation is scoped alongside any needed drainage, vapor barrier, or dehumidification work.

Longer-lasting results

Addressing moisture first means the insulation you install actually keeps performing for years.

Our four-step process

  1. Inspect: Document moisture, drainage, structure, and site conditions.
  2. Explain: Review findings with photos and straightforward priorities.
  3. Install: Complete the agreed scope with careful home protection.
  4. Verify: Test components, clean the work area, and complete a walkthrough.
Common questions

Insulation Installation FAQs

Why does my old insulation keep getting wet and sagging?+

This is almost always a sign of an unaddressed moisture source, either ground moisture in a crawl space or humidity in a basement. Insulation added on top of that problem will keep failing until the moisture issue is fixed.

Should insulation be added before or after fixing moisture issues?+

Moisture issues should be addressed first. Installing insulation over an active moisture problem usually leads to it failing again within a year or two.

What R-value do you recommend for below-grade spaces?+

Recommendations depend on your specific space, local code requirements, and whether the area is conditioned or vented. We provide a specific recommendation as part of your inspection.
