What we check in newer homes

In 2000s homes we measure attic depth in several places, look at recessed lights and the hatch, and check the bonus room knee walls and the floor over the garage. Builder-grade insulation is often thin near the eaves and around the air handler. Rim joists are usually covered only with a batt. Each item goes on the written quote with its own price. In older homes in the borough center, we add a wiring check and look at the walls and stone or block foundations.

Code and climate

Dillsburg is in York County's Climate Zone 4A. Pennsylvania's code lists R-49 for ceilings and R-20 or R-13 plus R-5 continuous for walls. ENERGY STAR recommends R-60 for an uninsulated existing attic or adding R-49 over 3 to 4 inches. Older homes in the borough center usually fall far short; newer homes are closer but have gaps. Either way, sealing comes first, then depth. Northern York County winters are similar to York's, with January lows around 21F and about 25 inches of snow a year.
