Next Door in the County Seat
Spray foam insulation in New Philadelphia is a short drive for us. Wikipedia describes Dover and New Philadelphia as twin cities, and their high schools have played each other in football for more than a century. New Philadelphia is the county seat and largest city in Tuscarawas County, with 17,677 residents at the 2020 census and 8,122 housing units.
Older housing
Point2Homes' ACS summary shows about 29.7% of New Philadelphia's homes were built before 1940 and another 10.2% in the 1940s. Like Dover's older streets, these homes tend to have empty walls, old attic fill and leaky foundations at the rim joist.
WPA-era park, older neighborhoods
Tuscora Park was built as a Works Progress Administration project, and its stone gates and retaining walls still stand. Many of the surrounding streets date from the same decades or earlier.
What we usually recommend
Rim joist foam, attic sealing with blown-in to R-49 or more, and dense-pack walls where they are empty. In newer homes on the city's edges, the focus shifts to bonus rooms and garage ceilings.
Coordinating with Dover jobs
Because the two cities sit side by side, we often schedule New Philadelphia estimates on the same days as Dover visits, which keeps waits short. The quote format is the same: every space on its own line, with material, depth or thickness, R-value and price.
Older streets near downtown
Many New Philadelphia houses near downtown and along the older avenues were built before insulation was standard. Expect empty walls, an attic with a few inches of old fill and a basement rim joist open to cold air. Rim joist foam, attic sealing and a blown-in top-up are the usual first stage; dense-pack walls can follow.
