What the housing means for the work
- Some older houses. About 23 percent predate 1940, so some jobs start by removing old layers.
- Lead-safe work. 50 percent of homes were built before 1980. Atlas is an EPA certified lead renovator and follows lead-safe (RRP) practices on pre-1978 paint.
- 1980s and 1990s houses. 33 percent were built between 1980 and 1999. They were built to older energy codes, so attic air sealing is worth pairing with new windows or a roof.
- Delivered fuel. 77 percent of Cornish households heat mainly with oil or propane, so heat kept in by an air-sealed attic is fuel you do not have to buy.
- Wood heat. 18 percent heat mainly with wood. Around chimneys we keep roofing, siding and insulation work to the required clearances.
