Older Main Street Homes and Newer Edges
Spray Foam Insulation in Mount Joy covers a borough in northwestern Lancaster County. Pennsylvania Route 230 runs through the center as Main Street, 12 miles from Lancaster and 6 miles from Elizabethtown, and Little Chiques Creek crosses the eastern side of town. The borough had 8,346 residents at the 2020 census.
Older homes in the center
Older houses in the borough often have brick or stone foundations, balloon framing and attics that hold mixed old insulation. Air sealing the attic floor and the basement rim joist does the most good in those houses.
Newer neighborhoods
Newer homes on the edges of the borough usually have basements with long, exposed rim joists and attics that can use more depth. Owners finishing basements should foam the rim and walls before framing.
Near the creek
Houses on low ground near Little Chiques Creek should have dry basements before any foundation wall insulation goes on. We check on the visit.
Zone 5
ENERGY STAR's guidance for existing attics in zone 5, which includes Lancaster County, is R-60 for an empty attic or adding R-49 over three to four inches.
Winter comfort
In older borough houses, cold floors on the first story usually trace back to the rim joist and any open chases in the basement. Foaming the rim and sealing the chases makes a noticeable difference in a single day of work, and it also helps keep pipes near the outside walls from freezing.
Rural properties nearby
The townships around Mount Joy hold farms and rural homes with barns and shops. We insulate those too, usually with closed-cell foam on steel or wood walls and roofs.
