Insulation Before & After in Santa Clarita, CA
Photos don’t lie. A blower-door reading of 4,800 CFM50 dropping to 2,200 tells one story; the thermal camera image of a sealed top plate tells another. We’ve documented every job we’ve finished in Santa Clarita since 2016 - over 9,000 homes - because homeowners should see what they’re paying for before anyone lifts a tool. Here’s what that looks like.

Attic Air Sealing + Blown-In Fiberglass in Saugus
The homeowner’s PG&E bill had climbed 34% over two winters. We found a 1,400 square foot attic in Saugus with original 1970s batts compressed to R-11, plus visible daylight through the top plates where wiring and plumbing stacks had never been sealed. Our crew spent the first day on hands and knees with a foam gun - sealing can lights, bath fan housings, and every penetration through the ceiling plane. Blower-door test read 4,200 CFM50 before sealing, 2,100 after. Then we blew in GreenFiber cellulose to R-49. The written scope and before-and-after blower-door numbers went to the homeowner that evening, along with 47 photos from the Documented Photo Record.
Crawl Space Encapsulation & Vapor Barrier in Valencia
A Valencia ranch built in 1984 had a dirt crawl space that smelled like mildew every time the HVAC ran. Relative humidity down there held at 78% through October. We removed the degraded fiberglass batts falling from the joists, graded the soil, and laid a 12-mil reinforced polyethylene vapor barrier - seams overlapped 12 inches and sealed with acrylic tape, walls wrapped to grade, piers individually sealed. Then we closed the vents and installed a Santa Fe dehumidifier set to 55%. The homeowner got the written price before we started, the blower-door numbers showing the envelope improvement, and 63 photos documenting every square foot of membrane.
Spray Foam Insulation in Canyon Country Garage Conversion
A Canyon Country homeowner had converted their garage to a music studio but couldn’t keep it below 82 degrees in July. The 2×4 walls had empty cavities and a plywood ceiling with zero insulation against the unvented roof deck. We applied 3 inches of Icynene closed-cell spray foam to the walls for R-19 and 5 inches to the roof deck for R-34, creating a conditioned attic space. The foam also sealed the rim joist and every electrical penetration. No more thermal bridging through the studs. The room now holds 74 degrees with a single mini-split. Written scope, blower-door comparison, and 38 photos delivered same day.
Radiant Barrier + Attic Cleaning in Newhall
A 1990s two-story in Newhall had attic temperatures hitting 145 degrees in August, forcing the upstairs AC to run 14 hours daily. Previous owners had left rodent droppings, compressed batts, and a disconnected flex duct dumping conditioned air into the attic. Our crew removed all contaminated material, HEPA-vacuumed the deck, sealed the duct with mastic, and stapled Owens Corning radiant barrier sheathing across the rafter bays. Attic peak temperature dropped to 108 degrees on the next 96-degree day. The homeowner received the written price beforehand, the 365-Day Done Right Promise in writing, and a photo record showing every step including the mopped deck before the barrier went up.
Insulation Removal & Replacement in Stevenson Ranch
A Stevenson Ranch home had suffered a roof leak that saturated R-30 batts in a 600 square foot section. The insulation never dried - mold grew, the drywall ceiling stained, and the homeowner’s allergies flared every time the attic fan cycled. We contained the affected area, removed the contaminated batts and vapor barrier, treated the deck with an antimicrobial, and let it dry for 48 hours. Then we air-sealed the full attic plane - not just the repair section - and blew in Knauf EcoFill to R-49 throughout. Blower-door reading: 3,800 CFM50 before, 1,900 after. The written scope specified the drying wait, the antimicrobial product, and the full-attic air seal. Photos numbered 1 through 52.
Wall Insulation Dense-Pack in Old Town Newhall
A 1956 California bungalow in Old Town Newhall had uninsulated 2×4 walls with lath and plaster. The homeowner could feel the afternoon Santa Ana winds through the living room drywall. We drilled 2-inch holes at stud bay spacing, dense-packed each cavity with GreenFiber cellulose at 3.5 pounds per cubic foot - enough to settle and resist convection without compressing - then patched with matching plaster texture. No gut renovation needed. The blower-door test showed the real number: 5,100 CFM50 before, 3,400 after. The written price covered the patchwork and paint matching. The photo record included every drilled hole location and the patched wall before we left.
