Old Center, Newer Edges
Spray Foam Insulation in Doylestown covers two very different kinds of houses. The borough sits on high ground at about 456 feet, and Wikipedia notes that its elevation and lack of water power kept heavy industry away. Its center holds older houses around the county seat, while more than 1,600 homes went up in the borough during the 1960s and 1970s.
Older houses in the center
Historic homes in the borough often have balloon framing, plaster walls and masonry. We concentrate on attic and rim joist air sealing and on careful wall work where it is safe, avoiding anything that traps moisture against old masonry.
1960s and 1970s homes
Houses from those decades usually have thin attic insulation, thin wall batts and unsealed rim joists. Sealing the attic and adding depth, then foaming the rim joist, is usually the best place to start.
Snow and storms
Doylestown averages 30 to 36 inches of snow a season, more than the river towns to the south, and its annual precipitation is 47.45 inches. On September 16, 1999, 7.11 inches of rain fell. More snow means more potential for ice dams from a leaky attic.
Planning work in a historic district
Parts of the borough are historic districts, and exterior changes may need review. Interior insulation work, such as attic sealing and rim joist foam, generally does not change how a house looks from the street. If a project involves exterior vents, siding or roof work, check with the borough before work starts, and we will plan around any requirements.

Doylestown Questions
Can you insulate a plaster-walled historic house?
Often yes, by dense-packing cavities through small holes and patching them, where the wall construction allows. We check first and skip walls where it would risk moisture problems.
Why do I get ice dams?
Heat leaking into the attic melts snow on the roof, which refreezes at the cold eaves. Sealing the ceiling and adding insulation stops most of that.
Do you work in Doylestown Township too?
Yes, along with Buckingham, Plumstead and New Britain nearby.
Does insulation change how my house looks from outside?
Attic and rim joist work does not. Wall filling from outside uses plugs that are set back into the siding. Exterior changes in a historic district may need review.
