Our Services

Spray Foam Insulation

Spray foam expands to fill every gap and void. It seals air leaks in one step—no gaps, no compression. Perfect for attics, walls, and crawl spaces in Fairfax homes built with irregular framing or missing sections.

  • Closed-cell foam: Waterproof, supports structure, R-value R-6 to R-7 per inch.
  • Open-cell foam: Lighter, cheaper, R-3.5 to R-4 per inch, allows vapor pass-through.
  • Meets Fairfax's R-49 attic requirement for vented spaces.

Commonly used in Mantua and Kings Park West where older homes have cathedral ceilings or complex roof angles.

Blown-In Attic Insulation

Fast, cost-effective. We blow cellulose or fiberglass into attic cavities to reach required R-values. We install baffle supports to keep material in place near eaves and vents.

  • Safe access: We build containment walls so you can still walk in your attic.
  • Reaches R-38 or R-49 depending on attic type and location in Fairfax.
  • Great for single-story ranch homes common in Fairfax Farms area.

Ideal upgrade for homes with less than R-30 existing insulation.

Wall Insulation & Removal

We remove old, damaged, or settled insulation and replace it with spray foam injection or blown-in fill. Townhomes in Old Town and condos in Fair Lakes often benefit from whole-wall sealing.

  • Injection foam fills cavities without opening walls.
  • Removal of damaged batts prevents mold and drafts.
  • Meets R-13 or R-15 wall code requirements.

Homeowners report noticeably warmer winters and cooler summers after wall insulation upgrades.

Why Local Expertise Matters

Northern Virginia R-Value Code: Fairfax requires R-49 for vented attics and R-60 for unvented. We guarantee compliance on every project.

Fairfax winters are cold; poor attic insulation wastes heating dollars fast. Historic homes and midcentury ramblers in neighborhoods like Mantua and Pine Ridge are notorious for under-insulation—often only R-3 to R-10 from the original build.

Homeowners here deal with ice dams, drafty second stories, and higher utility bills. Proper insulation stops heat loss and improves comfort year-round. Many Fairfax residents upgrade when they notice cold bedrooms in winter or moisture stains in crawl spaces.

We're familiar with Fairfax building inspections, permit requirements, and the specific building types in neighborhoods like Kings Park West and the historic Old Town district.

Frequently Asked Questions

Do I need a permit for attic insulation in Fairfax?

Simple insulation additions generally don't require a permit; however, removal of old material or major energy work may trigger inspection requirements. We check local rules and can help coordinate if needed.

What R-value do I need in my Fairfax attic?

Fairfax requires R-49 for vented attics and R-60 for unvented. Existing homes below R-30 are exempt from code, but upgrading saves energy immediately and prevents ice dams.

How long does a spray foam or blown-in insulation project take?

Most attic projects finish in one day. We protect your home, complete the work, and clean up so you're back to normal same day or next morning.

Will insulation stop my ice dams?

Proper attic insulation reduces heat loss through the roof, which helps prevent the ice-melt cycle. It's especially effective when paired with ventilation and air sealing.

Can you remove and replace old insulation?

Yes. We safely remove settled, damaged, or contaminated insulation and replace it with new spray foam or blown-in material to code.

Do you serve townhomes and condos in Fairfax?

Yes. We work on townhome attics, shared walls, and condo crawl spaces throughout Old Town, Fair Lakes, and other communities. Some HOAs require notice—we can advise.
