What goes wrong in Skagit County homes
1980s and 90s construction and polybutylene
30% of homes were built between 1980 and 1999. Polybutylene supply pipe was installed widely in US homes from about 1978 to 1995, so houses from these years are worth checking for gray plastic pipe stamped PB2110, usually visible at the water heater or under sinks. Insurers and buyers often ask about it. See polybutylene replacement.
Winter freezes
43% of homes here were built before 1980, when pipes were more often run through exterior walls and uninsulated crawl spaces. In a cold Washington winter those are the lines that freeze and split. See frozen and burst pipe repair.
