Lexington's mill-era homes and Davidson County farms sit on red clay, with old attics that bake in the summer heat and crawl spaces that sweat with humidity year-round. Winston-Salem Spray Foam Insulation has been sealing and insulating homes and metal buildings across Lexington (27292) and the surrounding area since 2012, because the Piedmont's moisture and temperature swings demand more than blown-in fiberglass.
Whether you own a 1920s mill house on brick piers, a 1950s ranch with a flattened attic, or a metal barn that drips with condensation, our team knows what works in Davidson County. We start with a free on-site assessment, write estimates with R-value and thickness specs, and spray the foam right so you don't have to call us back.
Spray Foam Insulation in Lexington (27292)
Lexington's building stock runs from tobacco-era brick mill houses and farmsteads to 1950s ranches and modern two-stories. Most sit on vented crawl spaces over red clay, with attics that see 130 to 150 degrees Fahrenheit through humid summers. Fiberglass and cellulose absorb moisture, sag, and lose R-value. Closed-cell foam stops moisture cold, holds its R-value year after year, and seals the air leaks that make your cooling and heating work twice as hard.
We spray attics, crawl spaces, rim and band joists, garage ceilings, and the walls of metal barns and barndominiums. We remove old insulation that has failed or gotten damp, and we seal the air leaks around your HVAC ducts, rim joists, and foundation. Every estimate names the R-value and thickness we are putting in, so you know exactly what you are paying for.

How a Job Works in Lexington
We start with a free on-site visit. We look at your attic, crawl space, or barn, measure the areas to be sprayed, check for moisture or failed insulation that has to come out first, and explain what open-cell or closed-cell foam will do for your home and your bills. If insulation has to be removed, we tell you the cost upfront. We write a detailed estimate with R-value, thickness, and the total board feet we will spray.
On the day of the work, our team sets up mechanical ventilation to manage the odor during cure. We spray the foam at the correct thickness in each pass, following the manufacturer's ratio and drum temperature. Once the foam is cured, we clean up and walk through the job with you. The space is ready for normal use within twenty-four to forty-eight hours, and we leave your property clean.
If the moisture or the leak has to be fixed first, we will tell you. We do not spray over wet insulation, standing water, or a leaking roof. We fix the problem or we walk away.
Attic spray foam in Lexington typically runs from $1.50 per square foot for open-cell to $1.20 per board foot for closed-cell, depending on the R-value you need and whether old insulation has to come out first. A crawl space might start at $2,500 to $3,500. Rim joist and band joist sealing runs from $650. Wall injection foam for a closed wall runs around $2 per square foot. Insulation removal alone is from $950, and a full replacement with new foam starts at $2,800. The final price depends on the square footage, the thickness and R-value specified in the estimate, whether you choose open or closed cell, and what has to be removed or repaired before we spray. Call us at (336) 608-5235 for a free estimate with no obligation. We will measure your space, explain your options, and give you a price in writing.
