Spray Foam Insulation in Highland - Same-Day Service, Done Right the First Time

Fast, Reliable Spray Foam Insulation Across Highland

Spray foam insulation in Highland typically costs $2,800 – $6,400 for a full attic retrofit and $3,900 – $7,800 for wall cavity injection in an average 1,200 – 1,800 sq ft ranch home. Most jobs are completed in one day, and we answer the phone live at (510) 896-3857 when you call. Highland’s older housing stock, especially in East Highlands, means most homes need air sealing just as much as insulation, and closed-cell foam does both in a single pass. If your 1950s – 80s home still has the original rock wool or settled fiberglass in the attic, you’re losing money every month the temperature swings.

Highland homeowners call us because we show up the way we say we will. Before any technician arrives, you get their name and photo by text or email.

That’s the Threshold Standard, and it applies to every job we run in Highland.

Our Spray Foam Insulation team works on Highland’s 1950s through 1980s single-story homes every week. We know what these attics look like: compacted rock wool, skipped bays, no air sealing around top plates. We’ve opened enough East Highlands attic hatches to know exactly what’s waiting. Homeowners in Highland consistently tell us two things after the job: upstairs rooms finally match the thermostat, and nobody knocked on the door they didn’t expect.

Garrett Sloane runs our operation with a simple rule: the price you’re quoted is the price you pay. No change orders halfway through. No “we found something” upcharges. Every Highland job gets a written price before work starts, and it’s covered by our 365-Day Done Right Promise for labor and materials. If the repair fails, we come back free. That’s it, in writing.

Spray Foam Attic Insulation in Highland

Spray Foam Attic Insulation is the single highest-impact upgrade for Highland homes built before 1990, and it solves the problem that’s costing you the most: attic heat radiating through ceilings during 100°F summers. In a typical Highland ranch, the attic is unconditioned, vented, and sits directly on top of your living space. When outdoor temperatures hit triple digits, that attic cavity can reach 140°F, and all that heat presses down through whatever insulation is left.

What we do in a Highland attic job: remove and dispose of the old compressed fiberglass or rock wool, air-seal every penetration (top plates, wire chases, recessed can lights, flues), then apply the spray foam. Closed-cell foam goes around the perimeter and air-seal points first, then open-cell fills the field of the ceiling deck. For homes with original rock wool that has compacted to roughly R-11, this retrofit brings the attic up to R-38 or better, which is what today’s California energy code requires.

What a Highland Attic Retrofit Includes

Full removal of old insulation is part of the job, not an add-on. You can’t spray foam over compacted rock wool and expect it to perform. The old material comes out, the attic gets a once-over for rodent damage or roof leaks, and only then do we seal and spray. That’s the only way the foam bonds properly to the ceiling deck.

Attic Retrofit Pricing in Highland

A standard 1,000 – 1,400 sq ft Highland attic runs $2,800 – $4,200 for open-cell foam to R-38 including old insulation removal. Closed-cell jobs run $4,100 – $6,400 for the same footprint. The price difference comes down to the R-value per inch and the vapor-permeability profile. We’ll tell you which one fits your house and your budget, in writing, before any work starts.

Spray Foam Wall Insulation in Highland

Spray Foam Wall Insulation targets the second-biggest thermal leak in Highland homes: uninsulated or poorly insulated wall cavities in ranch and hillside houses from the 1950s through 1980s. When those walls were built, code didn’t require the levels that apply today, and many Highland homes have empty 2×4 cavities between the drywall and the exterior stucco or siding. Hot outside air pushes through cracks around outlets, windows, and baseboards all summer, and your AC runs nonstop fighting it.

We install wall foam from the exterior when possible, drilling small access holes through stucco or siding at each stud bay, then injecting closed-cell foam that expands into the cavity and air-seals the wall assembly. For interior-only access jobs, we work through drywall and patch cleanly afterward. Most Highland wall retrofits take one day, and you’ll feel the difference in rooms with west-facing walls within 24 hours.

Where Wall Foam Matters Most in Highland

West-facing walls absorb the full afternoon sun, and on a 104°F day, the exterior surface can hit 150°F. If the wall cavity is empty, that heat conducts straight through studs and radiates into the room. Closed-cell foam at 3.5 inches in a 2×4 wall gives you R-20-plus plus a vapor barrier, which matters when overnight temperatures drop near freezing in winter and warm, moist indoor air tries to escape through the wall assembly.

Wall Retrofit Pricing in Highland

Exterior-injection wall foam for a typical 1,200 – 1,600 sq ft ranch runs $3,900 – $7,800 depending on access, siding type, and how many walls are done. We price it flat per square foot of wall surface, so you know the number before we start. Free estimates always, and the written price is fixed.

Trusted Brands We Service in Highland

We stock and install spray foam from Owens Corning, Johns Manville, and Icynene, plus air-sealing materials from Knauf and Demilec. Having multiple brands on hand matters in Highland because older homes need different foam profiles depending on the assembly: a 1960s East Highlands attic with open framing and vented eaves takes open-cell fine, while a 1980s hillside home with low-slope roof decking needs closed-cell for the vapor impermeability. We match the product to the house, not the other way around. No one-size-fits-all foam.

Common Spray Foam Insulation Problems We See in Highland Homes

• Settled or missing attic insulation in 1950s – 80s homes. Upstairs rooms run 10 – 15°F hotter than the rest of the house in summer. Blown-in or batts have compacted, and the attic is acting as a radiant ceiling heater.
• Uninsulated wall cavities in older ranch homes. Outside air infiltrates through outlet boxes, window frames, and baseboard gaps. Your AC runs constantly and you still can’t hold a setpoint on hot afternoons.
• Compacted rock wool in East Highlands attics. Original rock wool loses its air-trapping ability after 40 – 60 years, leaving effective values around R-11. The attic becomes a heat sink that pumps warmth back into living spaces long after the sun drops behind the San Bernardino Mountains.
• Air-seal failures at top plates and penetrations. Even newer insulation underperforms when warm air rises through wall top plates, wire chases, and can-light housings. Sealing those first is the difference between a real fix and a Band-Aid.
