Insulating a City of 1920s Houses

Spray Foam Insulation for Asheville homes starts with understanding how old most of the city's neighborhoods are. Asheville prospered in the 1910s and 1920s, and that boom produced the Art Deco downtown, the Arts and Crafts landmarks around Grove Park, and the Victorian houses now protected in the Montford Area Historic District. Those houses were built before insulation was standard, and most still have open paths for air from crawl space to attic.

Climate in plain numbers

The city sits at about 2,130 feet. Wikipedia's 1991 to 2020 climate table shows a January daily mean of 38.7F, about 10.3 inches of snow per year and 49.59 inches of precipitation. That mix means heating in winter, cooling and dehumidifying in summer, and moisture risk year round under the house.

Where we usually start

In older Asheville houses we often begin with the crawl space and the attic on the same visit. Sealing the bottom and top of the house stops the stack effect that pulls cold air in low and pushes warm air out high. Closed-cell foam on crawl space walls and rim joists, and sealed bypasses with blown-in on the attic floor, cover a large share of the savings.

Historic districts

If your house is in a local historic district, exterior changes can need review. Most insulation work happens inside the house and below or above the living space. Wall insulation drilled from the outside is the exception, and we can drill from inside instead where that is simpler.

Spray foam insulation cost in the city

City jobs vary more than most. A bungalow in West Asheville with a low crawl space and a cramped attic costs more per square foot to reach than a ranch in East Asheville with easy access. HomeGuide's national figures put a spray foam attic at $3,000 to $8,000 and crawl space encapsulation at $3 to $10 per square foot, but parking, access through finished rooms and the height of the crawl space set your number. We price each space on its own line.

Asheville Questions

Does my old Asheville house need a vapor barrier?

It depends on the space. Crawl spaces benefit from a ground liner and sealed walls. In walls and attics of older homes, controlling air leaks matters more than adding a plastic sheet, and the wrong vapor barrier can trap moisture.

Can spray foam go in a Montford-era house?

Yes, mainly in the crawl space, rim joist, attic bypasses and any open framing. Closed plaster walls are usually better with dense-pack cellulose.

What is the best first project for an older Asheville home?

Usually sealing the crawl space and the attic floor together, because they stop the stack effect at both ends of the house.

Yes. We cover every Asheville neighborhood, plus Biltmore Village, Kenilworth, Haw Creek and the areas off Tunnel Road.
