Spray Foam Insulation in Willow Street, PA

Spray Foam Insulation in Willow Street covers a suburban community south of Lancaster city. Willow Street is an unincorporated community, named for the willow trees that once lined both sides of its main road in the early 1900s. It had 7,578 residents at the 2010 census, and the 2000 census counted 3,323 housing units across its 5.4 square miles.

Drainage between creeks

Most of the community drains north to Mill Creek, a tributary of the Conestoga, while the southern part drains south to Pequea Creek. Low spots near either can see damp basements, so we check moisture before insulating below grade.

Typical work

In suburban houses like these, the main targets are the attic, the rim joist, rooms over garages and basements being finished. Each is a separate line on the quote, so you can decide what to do now and what to plan for later.

Attic guidance

ENERGY STAR's zone 5 guidance is R-60 for an attic with no insulation and adding R-49 where three to four inches already exist. Lancaster County falls in Pennsylvania's central Zone 5 group.

Room over the garage

A bedroom or bonus room over an attached garage has cold air below and often thin insulation in its kneewalls and slopes. ENERGY STAR recommends R-30 for floors over unheated space in zone 5. Closed-cell foam under the floor seals and insulates in one step and keeps garage fumes out.

Ranches with big attics

Older single-story ranches have large attic floors relative to their size. Sealing the ceiling plane and blowing loose fill to depth is usually the most cost-effective upgrade in that kind of house.
