Burst Cast-Iron Pipe in 1951 Pier-and-Beam Home — Discovered at 2 AM
A homeowner woke at 2 AM to water under the bedroom door. A cast-iron supply line original to the 1951 build had cracked, leaking for ~4 hours into the crawlspace and up through the subfloor. The crawlspace held 6 inches of standing water across 280 sq ft when our crew arrived.
The pier-and-beam foundation put the wooden subfloor joists in direct water contact — the most vulnerable structural element in this construction type. Moisture mapping found water had wicked 18 inches up the kitchen drywall and the original heart pine subfloor showed early swelling at seams. The homeowner feared losing the floor, which is irreplaceable in a 1951 College Park bungalow.
We deployed submersible crawlspace pumps, truck-mounted floor extraction, and 14 air movers + 6 dehumidifiers over two levels simultaneously. Targeted directed-heat drying over 4 days brought the heart pine subfloor from 34% to 11% moisture — fully within dry standard.
