Winston-Salem's homes sit on red clay, in vented attics that hit 130 to 150 degrees in summer, and over damp crawl spaces raised on brick piers. That combination drives every insulation decision we make. Spray foam seals the air leaks that fiberglass cannot, stops condensation before it starts, and holds R-value in the heat and humidity of the North Carolina Piedmont.
Since 2012, we have sprayed attics in Ardmore and Washington Park, injected foam into the solid brick walls of West End Craftsman bungalows, sealed crawl spaces under homes in Sherwood Forest and Konnoak Hills, and finished the rooms over garages in Reynolda and Clemmons where the air conditioning has never reached. Winston-Salem Spray Foam Insulation knows the neighborhoods, the building stock, and the moisture problems that come with them.
Spray Foam Insulation in Winston-Salem (27101)
Winston-Salem's housing runs from 1700s Moravian brick and timber frames through 1900s mill-era Craftsman bungalows on brick piers to 1950s ranches and split-levels to modern two-stories with vaulted ceilings and finished rooms over the garage. Most homes sit on vented crawl spaces or daylight basements cut into the sloped terrain of the foothills. Above nearly all of them, an air handler and ductwork live in a vented attic that bakes in summer and draws humid air through every gap and seam. Red clay holds moisture. The summer humidity and winter ice storms mean condensation and damp insulation happen fast.
Spray foam stops both. Closed-cell foam seals crawl spaces against moisture and holds R-value when humidity is high. Open-cell foam in attics above conditioned space breathes and dries, and costs less. Wall injection fills the cavities in solid-brick homes where blown-in insulation cannot reach. Rim and band joists where the rim board sits on the brick pier are where cold air and moisture enter in winter. We have been sealing those details across Winston-Salem and the surrounding area for over a decade. We know what works here.

How a Job Works in Winston-Salem
We start with a free on-site visit. We look at the attic, crawl space, or walls that need work, check for moisture, damp insulation, or damage, and measure the area to be sprayed. We ask what the problem is: a room that will not cool, a summer electric bill that has become unaffordable, condensation on the rim joist in winter. We give you a written estimate with R-value and thickness specifications so you know exactly what you are getting and why.
On the day of the work, our fully insured crew sets up mechanical ventilation so fumes leave the property during cure. We spray the foam to the thickness and density the estimate calls for, controlling the ratio and drum temperature so the foam cures correctly. If insulation has to come out first, we remove and haul it. We work around occupied homes and give you a clear re-entry window, typically twenty-four to forty-eight hours depending on the area sprayed and the ventilation. We clean up after ourselves and walk through the finished work with you.
Attic spray foam in Winston-Salem typically runs from $1.50 per square foot for open-cell foam on top of existing insulation to higher per-square-foot costs for closed-cell or when insulation has to be removed first. A crawl space spray foam job starts around $2,500 and scales with the square footage and the condition of the space. Wall injection foam for a solid-brick home runs from $2 per square foot. Rim and band joist sealing starts at $650 and depends on the linear feet of rim and the access. Insulation removal runs from $950 and scales with volume. The cost drivers are the area to cover, the R-value and thickness you need, whether you choose open or closed cell, what has to be removed before we spray, and how tight the access is. We give you a free estimate at (336) 608-5235 that spells out all of it.
