Insulating an Old Borough That Keeps Growing
Spray Foam Insulation in Elizabethtown deals with houses from many eras. By the accepted account, Captain Barnabas Hughes laid out the town in 1753 and named it for his wife. Elizabethtown became a borough in 1827, got a railroad in the 1830s, and stayed mostly agricultural until the early 1900s, when the Klein Chocolate Company and several shoe factories opened. Elizabethtown College was founded in 1899.
Older houses near the center
Homes from the 1800s and early 1900s often have stone or brick foundations, balloon framing and attics with old insulation. Rim joist foam and attic sealing are the usual first steps. If we find knob-and-tube wiring, an electrician checks it before any insulation covers it.
Newer houses
The 2020 census counted 4,665 housing units in the borough, with 3.7% vacant and a homeowner vacancy rate of 0.7%. Newer homes on the edges and in surrounding townships often have bonus rooms and basements that benefit from foam.
Climate
Elizabethtown has a hot-summer humid continental climate, with average monthly temperatures from 30.1°F in January to 74.9°F in July, and sits in hardiness zone 6b. Conoy Creek drains the borough southwest to the Susquehanna.
Where to start
In most Elizabethtown houses, the attic and the rim joist give the most comfort for the money. If you are finishing a basement, foam the walls and rim before framing.

Elizabethtown Questions
Do you work outside the borough?
Yes, including Mount Joy Township, West Donegal and Conoy townships nearby.
Is rim joist foam worth it in an older house?
Usually yes. Older rims are often bare or have gaps at the sill, and closed-cell foam seals and insulates them.
Can insulation go over old wiring?
Not over live knob-and-tube. An electrician should check it first.
