Local insulation context

What do La Mesa 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.

Pricing

How much does insulation cost in La Mesa?

Most La Mesa 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.
