Insulation Services in Long Beach, CA
Long Beach insulation contractors in this directory cover Belmont Shore, Naples, Bixby Knolls, California Heights, and downtown Long Beach. Most pre-1980 Long Beach Spanish and bungalow-style homes have minimal attic insulation (R-11 to R-19 of compressed batts) and no wall insulation at all. Topping up the attic to R-38 with blown fiberglass or cellulose runs $1.40-$2.20 per sq ft. Drilled-and-fill wall insulation through stucco runs $2.50-$4.50/sq ft of wall area.
Long Beach falls in IECC Climate Zone 3B (warm-dry coastal) — code asks for R-38 attics and R-13 walls. Most pre-1980 stock falls dramatically short. The salt-air environment near Belmont Shore and Naples means stainless or galvanized fasteners and corrosion-resistant baffles are worth specifying.
Frequently Asked Questions
- What R-value should my Long Beach attic have?
- IECC Climate Zone 3B asks for R-38 attics. Most pre-1980 homes have R-11 to R-19 — topping up with blown insulation typically runs $1.40-$2.20/sq ft and is the highest-ROI single energy upgrade for older Long Beach stock.
- Can I retrofit insulation into my older Long Beach stucco walls?
- Yes — drilled-and-fill cellulose or fiberglass through small holes in the stucco is the standard approach. Plug holes are patched and matched. Cost runs $2.50-$4.50/sq ft of wall area; expect 4-8 weeks of lead time for a typical bungalow.
- Are there rebates for Long Beach insulation upgrades?
- SoCalGas and SCE both offer home-performance rebates that vary quarterly. The 25C federal tax credit covers 30% of qualifying insulation up to $1,200/year. Long Beach Energy customers should also check the city's rebate listings directly.
