Spray Foam Insulation in Lancaster, PA

Spray Foam Insulation in Lancaster city usually involves older houses. Lancaster was laid out by James Hamilton in 1734, incorporated as a borough in 1742 and as a city in 1818, and served as Pennsylvania's capital from 1799 to 1812. The 2020 census counted 23,769 housing units, with 6.9% vacant. Much of that stock is brick rowhomes, twins and townhouses with stone or brick foundations, shared walls and shallow attics.

Rowhomes and shared walls

A rowhome loses less heat through its party walls than a detached house does, so the front and back walls, the roof and the basement matter more. The rim joist at the front and back of the basement is usually bare and leaks along its whole length. Closed-cell foam there is one of the most effective upgrades in a city house.

Roofs with little or no attic

Many city houses have low-slope roofs with a shallow attic or none. Where there is crawl space above the top ceiling, we seal and insulate it. Where there is not, roof replacement is the best time to add insulation from above, and we explain the options.

Brick needs to breathe

Solid brick and stone walls dry by letting moisture pass through. We do not spray foam on the inside of old masonry walls that need to dry. Framed walls, attics and rims are where we focus.
