What do San Diego insulation systems need?
Central San Diego housing stock is mostly 1950s through 1980s construction. Most attics still hold the original R-11 or R-19 insulation, settled and dirty. Walls in pre-1980 homes are often empty, which we can dense-pack from the interior or exterior without removing drywall. The standard upgrade — attic to R-49, walls dense-packed, plus building-envelope air-sealing — pays back in 3–5 years on cooling alone and adds resale value beyond that.
How much does insulation cost in San Diego?
Most San Diego attic insulation upgrades run $1.40 to $2.80 per square foot installed, depending on R-value target and access. A typical 1,500 sq ft attic going from R-19 to R-49 with air-sealing lands in the $2,500 to $4,500 range. Spray foam is higher — $1.50 to $5.50 per board foot — but does insulation and air-seal in one application. Insulation removal runs $1.50 to $3 per square foot.

Same-week scheduling on most San Diego estimates. The job itself usually books 1–2 weeks out depending on scope. Emergency removal (rodent damage, water damage) gets priority dispatch.
Do you do spray foam in San Diego?
Yes. Open- and closed-cell spray foam, plus rigid foam board, batts, blown-in cellulose, and dense-pack walls. We pick the method that fits your assembly, not the one we want to sell.
What R-value do I need in San Diego?
Central San Diego sits between coastal humidity and inland heat. San Diego attics typically hold 1980s or older insulation that has settled to R-15 or worse. Going to R-49 cellulose plus air-sealing is the standard upgrade and pays back in 3–5 years on cooling. California Title 24 sets R-30 minimum on a roof alteration and R-38 on most new or fully reinsulated attics; we usually recommend R-49 for the comfort difference at marginal extra cost.
