Crawl Space Winterization

Crawl Space Winterization in Greater Raleigh

Avoid frozen pipes, cold floors & high heating costs with the proper protection

Falling insulation and uninsulated ducts in crawl space

Properly insulating & sealing the crawl space can control humidity in the crawl space, which can form condensation on surfaces like ducts and pipes, leading to mold, rot & leaky ducts.

Is your home uncomfortably cold during the winter months, causing you to turn up your heating system and increasing your utility bills? Regional Foundation Solutions can help by winterizing your crawl space!

By air sealing and insulating crawl space rim joists, walls, and floors, the cold is unable to penetrate your below-grade space, helping you avoid costly repairs from frozen and burst pipes and ensuring the frigid air won't leak into your home or affect the performance of your HVAC unit.

Sealing cold crawl spaces fix:

  • Cold floors above the crawl space.
  • Cold drafts from the crawl space.
  • High heating bills.
  • Crawl space ductwork, cooling heated air from the furnace.
  • Frozen pipes due to weak insulation.

Faulty crawl space insulation & cold air

Fiberglass insulation in crawl space ceilings leaves your home vulnerable to frozen pipes, cold floors, and high heating bills.

Ductwork in a vented crawl space means outside air and temperatures make your ducts cold in the winter and hot during the summer, forcing your HVAC system to work overtime to properly regulate home temperature, cutting system efficiency by as much as 25 to 40 percent.

Sealing out the cold in your crawl space

Let us permanently solve your cold weather problems – we don't just winterize crawl space pipes or vents, instead, we seal and winterize your entire crawl space foundation, bringing your plumbing and heating system inside your home's conditioned space. Here's how our process works:

  • Air seal & insulate the rim joist: Prevent frigid air from leaking in by sealing the gaps around the edge of your foundation and reduce heat loss by insulating the rim joist with foam insulation.
  • Insulate crawl space walls with rigid foam: We install SilverGlo™ rigid foam insulation against crawl space walls — it does what fiberglass can't, stopping air leaks, retaining R-value, and resists moisture.
  • Seal & insulate the crawl space floor. In colder climates, we install TerraBlock™ foam insulation on crawl space floors and cover it with our strong poly CleanSpace® moisture barrier, completing the sealing process and isolating from the outside.
