How does La Mesa's climate affect this service?
La Mesa is mid-century ranch and craftsman stock with original attic insulation now 55-plus years old. Mount Helix custom homes anchor the high end, La Mesa Village walkable craftsman the middle, and inland heat plus aging building envelopes make the upgrade-to-R-49 conversation easy on most addresses.. Central San Diego spray foam jobs lean toward conditioned attic conversions and rim-joist work in older La Mesa and Lemon Grove housing.
What's the difference between open- and closed-cell foam?
Open-cell is softer, lower R per inch (about 3.7), vapor permeable, and better at sound dampening. Closed-cell is denser, higher R per inch (about 6.5), structural, and a vapor retarder. Closed-cell costs more but does more in less space, we use it on rim joists, crawlspaces, and unvented roof decks.
Is spray foam safe?
Once cured, yes. During application the chemicals off-gas and the area must be vacated and ventilated for the cure window, usually 24 hours for residential. We follow SPFA guidelines and the manufacturer's re-entry time. We don't take shortcuts on this.
