Ceiling & Roof Leak Water Damage Repair in Downey, CA
The leak is traced above the stain and corrected, wet insulation comes out, the cavity is dried to a reading, and only then is the ceiling repaired. The leak is traced uphill from the stain and corrected before anything else. Soaked insulation comes out of the cavity, the framing and the back of the ceiling are dried and read to the dry standard, and only then is the ceiling repaired and painted, so the stain does not return through new paint.

Frequently asked questions
The stain keeps coming back through fresh paint. What is causing that?
Rust, most likely. These walls are plastered over steel lath, and a wall that stayed damp corrodes the lath inside the plaster. The staining is coming from behind rather than from the surface, so it bleeds through paint and patching compound alike. Sealing it only works once the wall is genuinely dry.
Is hard plaster worth keeping after a soaking?
Generally yes. It tolerates water far better than paper-faced board and stays sound where board would be finished. The work is in giving it a way to release: base and casings off, a small opening low on the wall, and air moved across it. What settles removal is corrosion staining or plaster that has lost its grip on the lath.
What does the drying look like in a mild month?
Unhurried, and that is the trap. Nothing in this climate forces a wall dry or keeps it wet, so a damp plaster wall can sit unchanged for weeks without anyone feeling urgency about it. Readings are taken on a schedule rather than when the room seems ready, because appearance here is a poor guide.
