Insulating Older Homes on the Delaware
Spray Foam Insulation in Bristol borough deals with some of the oldest houses in Bucks County. Bristol was settled in 1681, incorporated in 1720, and grew as the southern end of the Delaware Canal, with textile mills, foundries and, by the 1880s, wallpaper and carpet factories. Wikipedia notes the many historic and restored houses along Radcliffe and Mill streets, and the borough has several National Register historic districts.
What old construction means for insulation
Houses built in the 1700s and 1800s were never designed for insulation. Walls are often solid brick or balloon-framed with open cavities that run from the basement to the attic. Foundations are stone or brick, and the band where the framing meets the foundation leaks air along the whole perimeter. Air sealing those paths has a bigger effect in old houses than almost anything else.
Careful with masonry
Solid masonry walls need to dry. Spraying foam on the inside of an old brick wall can trap moisture and cause damage in freeze-thaw weather. We usually focus on the attic, the rim joist and any framed walls, and we explain what we would not do and why.
River weather
Bristol sits about 20 feet above sea level on the Delaware River. Its climate is humid subtropical, and Wikipedia's PRISM-based figures show an average annual extreme minimum of 5.1°F and 24 to 30 inches of snow a season. Humid summers and real winters both matter, and so does moisture in old basements near the river.

Bristol Questions
Can you spray foam the inside of my brick walls?
We usually advise against it on solid masonry, because old brick needs to dry to the inside. We focus on the attic, rim joist and framed walls, which often deliver more benefit with less risk.
My basement is damp. Can you insulate it?
Water comes first. If the stone or brick foundation leaks, insulation should wait until grading, gutters or drainage are fixed. The rim joist above can often be foamed regardless.
Do historic district rules affect insulation?
Interior insulation work usually is not affected, but exterior changes like new siding or vents may be. Check with the borough if your house is in a historic district.
