Old Houses Behind the Dike
Spray Foam Insulation in Morrisville often starts in the basement. The borough incorporated in 1804 at the site of an early Delaware River ferry, and Wikipedia notes a 30-foot flood control dike along the river, with the Falls of the Delaware just below. Older houses here sit on stone or block foundations close to the river, and keeping their lower levels dry is part of any insulation plan.
Rim joists and old foundations
In houses this age, the rim joist and sill are usually bare or covered with old batts. Closed-cell foam seals and insulates that band and slows moisture moving through the wood. It is one of the highest-value jobs in an older house.
Attics in older houses
Many Morrisville houses have attics with floored storage, old knob-and-tube wiring or a mix of insulation types from different decades. We check the wiring and condition before adding anything, and we flag anything that needs an electrician first.
Climate
Morrisville's climate is humid subtropical. Its hardiness zone is 7a, with an average annual extreme minimum of 1.6°F. Hot, humid summers make attic heat and moisture the main issues, and cold snaps test the rim and walls.
Early history
The area's first known settlement was a Dutch West India Company trading post from 1624 to 1627 on an island in the river. Robert Morris, financier of the Revolution, lobbied to put the nation's capital here, and his home Summerseat still stands.

Morrisville Questions
Should I foam my basement walls near the river?
Only if they are dry. If water comes through the walls, fix that first. The rim joist above the wall can usually be foamed regardless.
Can you insulate an attic with old knob-and-tube wiring?
Not until an electrician confirms it is safe or replaces it. Covering live knob-and-tube with insulation is a fire risk. We check on the visit.
Do you work across the river in Trenton?
Our service area is on the Pennsylvania side of the river around Morrisville and Lower Bucks County.
