Spray foam insulation and air sealing are among the most effective ways to improve your home's energy efficiency, comfort, and durability. At Lexington Spray Foam Insulation, we serve the Lexington area with a full range of services, from attic and crawl space foam to wall retrofits, rim joists, garages, and commercial projects. Pricing varies based on factors like project size, foam type (closed cell or open cell), accessibility, and the specific areas being insulated, but we're committed to providing transparent, competitive quotes so you know exactly what to expect.

| Service | Price | Details |
|---|---|---|
| Attic Spray Foam Insulation | From $1.50/sq ft | Lexington attics bake under summer sun and lose heat fast during winter cold snaps. We spray foam under the roof deck in Chevy Chase bungalows and Hamburg area homes, sealing the attic as conditioned space to cut cooling bills and stop ice-season drafts. |
| Closed Cell Spray Foam Insulation | From $1.20/board ft | Closed cell foam adds rigid strength to rim joists and walls across Lexington's older homes. We spray this high R-value-per-inch foam in basements and crawl spaces on limestone, where damp air pushes in after Bluegrass storms. |
| Open Cell Spray Foam Insulation | From $0.55/board ft | Open cell foam fills wall cavities and attic rafters with a soft expanding layer in Lexington homes. We use it for sound control and interior walls in mid-century ranches and newer subdivisions toward Masterson Station, where it expands to fill irregular stud bays. |
| Wall & Injection Foam Insulation | From $2/sq ft | Injection foam fills closed wall cavities in older Lexington homes without tearing out plaster or siding. We drill small holes from inside or outside to reach bungalows in Chevy Chase and Ashland Park, adding density that resists wind-driven rain and ice. |
| Crawl Space Spray Foam Insulation | From $2,500 | Lexington crawl spaces stay damp long after storms roll through limestone-based foundations. We seal the liner and spray foam the walls to block that moisture, cutting musty air and cold floors in homes across Jessamine and Scott counties. |
| Rim Joist & Band Joist Spray Foam | From $650 | Rim and band joists lose heat fast once Lexington's cold snaps and ice settle in each winter. We spray closed cell foam along this band around basements and crawl spaces, closing the gap where cold air slips into older homes near downtown. |
| Garage Spray Foam Insulation | From $1,200 | Garages and bonus rooms above them bake in Lexington's humid summers and chill fast in winter cold. We spray foam the garage ceiling and walls in newer subdivisions toward Hamburg, cutting the swing in rooms over garages and tightening the shared wall to living space. |
| Metal Building & Barndominium Spray Foam | From $1.75/sq ft | Barns and shops across the Bluegrass countryside take on condensation when humid summer air meets cool metal roofing. We spray foam the underside of the metal panels on barndominiums and farm buildings in Jessamine, Scott and Mercer counties to stop that drip. |
| Commercial & New Construction Spray Foam | Free commercial estimate | New construction around Lexington keeps adding roofs and wall cavities that need an air barrier. We work with builders and GCs across Fayette and Scott counties to spray foam new roof decks, walls and crawl spaces before drywall closes them in. |
| Insulation Removal | From $950 | Older attics in Chevy Chase and Ashland Park often hold thin, settled insulation that no longer performs. We remove old batts or blown-in material, clear rodent debris if present, and prep the deck for spray foam suited to zone 4A humidity. |
| Insulation Replacement & Re-Insulation | From $2,800 | Replacing worn insulation gives older Lexington homes a fresh air barrier for zone 4A's humid summers and cold winters. We pull old material from attics and walls near downtown and Hamburg, then install new spray foam sized to the home's framing and current energy code. |
| Air Sealing | From $650 | Air leaks around penetrations and top plates let drafts move through older Lexington homes. We seal rim joists, attic bypasses and crawl space gaps across Jessamine and Bourbon counties, cutting the stack effect that drives summer humidity and winter cold inside. |
What Affects the Price
- Project Size and Square Footage : Larger projects typically have lower per-unit costs. A 1,000 sq ft attic will have different pricing than a 3,000 sq ft space due to material efficiency and labor distribution.
- Foam Type (Closed Cell vs. Open Cell) : Closed cell foam ($1.20/board ft) provides superior insulation and moisture resistance but costs more than open cell foam ($0.55/board ft). Your climate and specific needs determine which is best.
- Location and Accessibility : Easy-to-reach attics and crawl spaces cost less than difficult-to-access areas. Steep roofs, tight spaces, or obstructed areas may require additional labor and equipment.
- Existing Insulation and Prep Work : If old insulation needs removal ($950+) or if air sealing is required ($650+), this adds to the total project cost but ensures proper installation and maximum performance.
