Dense Neighborhoods, Similar Problems
Spray Foam Insulation in Feasterville-Trevose covers a dense residential area split between Lower Southampton and Bensalem townships. Wikipedia describes the former census area as a relatively densely populated residential zone between the two communities' business districts; it was split into separate Feasterville and Trevose areas for the 2010 census. The 2000 census counted 2,649 housing units in the combined area.
Typical houses
If your house is a post-war ranch, Cape Cod or split-level, the attic is usually small and under-insulated, the exterior walls may have thin batts, and split-levels have rim joists and garage ceilings that leak.
Split-levels need special attention
Split-level houses have several short roof sections, a room over the garage, and rim joists at different heights. Each needs its own approach. We go through them one by one and price them separately.
Climate
The area's climate is humid subtropical, with plant hardiness zone 7a and an average annual extreme minimum of 1.2°F. Hot, humid summers make attic sealing a cooling upgrade as much as a heating one.
Rooms over garages and porches
Many houses here have a bedroom or family room over a garage or an enclosed porch. Those floors face unheated air from below, and they often feel cold in winter and stuffy in summer. Closed-cell foam on the underside of the floor seals and insulates in one step, and it also blocks garage air and fumes from reaching the room above. ENERGY STAR recommends R-19 for floors in zone 4A, which closed-cell reaches in a few inches.

Feasterville-Trevose Questions
How do you insulate a split-level house?
Section by section: the upper attic, the room over the garage, the rim joists at each level, and any cathedral sections. Each gets the method that fits.
Is the room over my garage worth insulating with foam?
Usually yes. Closed-cell foam in the floor stops cold and seals out garage fumes.
Do you serve all of Lower Southampton?
Yes, along with the Trevose side of Bensalem.
How thick does foam need to be under a floor?
ENERGY STAR recommends R-19 for floors in zone 4A. At R-5 to R-7 per inch for closed-cell, that is roughly three to four inches.
