Dunmore's Older Homes
Spray Foam Insulation in Dunmore works on a borough full of older houses. Point2Homes data shows 47.9% of Dunmore homes built in 1939 or earlier and 10.8% in the 1940s. Dunmore was settled in 1835 and incorporated in 1862, and anthracite coal, brick, stone and silk drove its population from 8,315 in 1890 to 23,086 in 1940. The 2020 census counted 14,042 residents.
Coal-era houses
Houses from Dunmore's boom years are often two-and-a-half-story frame homes with steep roofs, open wall cavities and stone or brick foundations. They need attic sealing, cellulose to depth, wall dense-packing and sill and rim foam.
Ground movement
Wikipedia notes that the Keystone landfill in Dunmore was built over mines known for ground subsidence. Settling elsewhere in the valley can crack foundations and open new air paths at the sill. We seal those gaps at the sill line; structural cracks need a structural fix first.
Occupied homes
The 2020 census counted 6,618 housing units with a homeowner vacancy rate of just 0.8%. About 54.6% of occupied homes are owner-occupied, per Point2Homes.
Roaring Brook
Stephen Tripp built a saw and grist mill on the Roaring Brook in 1820, the area's first business. Homes along the brook and in lower areas may have damp basements; we check before insulating below grade.
Code and zone
Pennsylvania's 2021 UCC took effect January 1, 2026. Lackawanna County is in PHRC's Central zone and OpenEI's Zone 5A.
Costs
HomeGuide puts an average attic job at $1,000 to $2,700 and rim joist foam at $2,000 to $2,500. Your written estimate is the price.
A typical Dunmore job
For a pre-war Dunmore frame house, a common plan is: block the open wall tops from the attic, seal around the chimney with metal and fire-rated sealant, seal the plumbing stack and light boxes, blow cellulose to depth, dense-pack the exterior walls, and foam the sill and rim in the basement. Each area is priced separately.
Gertrude Hawk and the neighborhoods
Dunmore is home to Gertrude Hawk Chocolates, founded in 1936, and the Keystone Industrial Park. Most residential streets, though, are lined with the same older frame houses the borough built during its coal and silk years.
