Insulation Before & After in Long Beach, CA
Photos don’t exaggerate. A blower-door test gives you a number; a thermal camera shows you a gradient; but a before-and-after photo gallery lets you see what “sealed first, then insulated” actually looks like in a Long Beach attic or crawl space. We’ve documented every job since 2016 - over 9,000 homes - and these are the transformations that stick with us.
Recent Transformations
Attic Insulation Removal & Replacement - Belmont Shore
The homeowner in Belmont Shore had owned the 1947 bungalow for eleven years and assumed the original insulation was “fine, just old.” What we found was R-19 batt compressed to roughly R-10 effective value, with visible gaps at the eaves where conditioned air was bleeding into the roof deck. We removed the degraded material, sealed the top plates and can-light penetrations, then installed blown-in fiberglass to a full R-38 depth. The blower-door test read 3,800 CFM50 before sealing and 2,100 after - a 45% reduction in envelope leakage. The written scope, the photo record, and the before-and-after numbers went into a folder the homeowner still has.
Crawl Space Encapsulation & Vapor Barrier - Bixby Knolls
Bixby Knolls sits on some of the most moisture-retentive soil in Long Beach, and this 1952 ranch had the classic symptoms: musty first-floor air, cupping hardwood, and a crawl space that smelled like a basement that had given up. We found exposed soil, standing water after rain, and mold-stained joists. Our crew installed a 12-mil reinforced vapor barrier sealed at all seams, closed and sealed the foundation vents, and ran a dehumidifier drain line to the exterior. The relative humidity in the crawl space dropped from 78% to 52% within 48 hours. Under Haven Standard, the homeowner got the written scope beforehand, the photo record after, and a 365-Day Done Right Promise on the encapsulation.
Spray Foam Insulation - Retrofit Wall Cavities - Naples
A full-gut renovation in Naples gave us access to wall cavities that hadn’t been open since 1963. The framing was honest - no rot - but the sheathing had gaps you could see daylight through, and there was zero insulation in the walls. We used closed-cell spray foam at 2 inches, which gave the homeowner R-14, an air barrier, and a vapor retarder in one application. The ACH50 dropped from 8.2 to 4.1 - meaning the house now exchanges its air volume roughly four times per hour under pressurization instead of eight. That’s the difference between a house that fights the Long Beach marine layer and one that ignores it.
Attic Air Sealing & Blown-In Top-Up - Signal Hill Adjacent
This 1978 split-level near the Signal Hill border had the usual suspects: gaps around the chimney chase, dropped soffits that acted as open conduits straight into the wall cavities, and a bath fan that had been dumping moist air into the attic for years. We don’t blow insulation over that. We sealed the chase with fire-rated foam and metal flashing, blocked the soffit drops with rigid foam and sealant, and vented the bath fan through the roof. Then we brought the blown-in cellulose to R-38. The crew documented every step - the photos show the pink foam around the chase, the blocked soffits, and the final even coverage. The homeowner got the folder, the numbers, and a written price that never changed.
Radiant Barrier Installation - Alamitos Heights
Alamitos Heights gets the afternoon sun full on the roof, and this 1986 two-story had a dark asphalt shingle roof deck that measured 148°F on a July afternoon. The attic air was 138°F. The HVAC ductwork was up there, fighting a battle it couldn’t win. We stapled perforated radiant barrier to the rafters - not the attic floor, which would have trapped moisture - and the roof deck surface temperature dropped to 112°F. Attic air temp fell 18°F. The ducts stopped sweating. The homeowner didn’t need more insulation; they needed less radiant heat gain, and the barrier gave it to them with a 15-year expected service life. The photo record shows the stapling pattern, the rafter spacing, and the temp gun readings.
Insulation Removal After Rodent Damage - Lakewood Village
The Lakewood Village homeowner called because the house smelled wrong - not musty, not gas, just wrong. We found rodent-compacted insulation with droppings, urine saturation, and tunnel runs through the fiberglass. That’s not a thermal barrier; it’s a biohazard. Our crew suited up, removed the contaminated material with HEPA containment, sanitized the deck and joists, and rodent-proofed every entry point with steel mesh - not spray foam, which they chew through. Then we sealed the envelope and installed new R-38 blown-in fiberglass. The smell left with the old insulation. The photo record includes the entry-point map, the mesh installations, and the final coverage. The 365-Day Done Right Promise covers the workmanship; the documentation covers everything else.
