Insulation Before & After in Buena Park, CA
Photos don’t exaggerate. A compressed fiberglass batt sitting an inch below the top plate, a crawl space with standing water against the sill plate, or a blower-door reading that drops by half - these are the outcomes we document on every job. Below are representative transformations we’ve completed in Buena Park and surrounding Orange County neighborhoods, with the problem, the work, and the measured result.
Recent Transformations
Attic Insulation Removal & Replacement - Buena Park Single-Story Near Knott’s Berry Farm
The homeowner called after a roof leak saturated the existing R-19 fiberglass batts. By the time we opened the hatch, the insulation had compressed to roughly R-11 and showed visible mold spotting on the paper facing. We removed all contaminated material, HEPA-vacuumed the deck, sealed top plates and can-light penetrations with fire-rated caulk and covers, then blew in new GreenFiber blown-in cellulose to R-38. The blower-door test read 3,800 CFM50 before sealing and 2,200 after. Under Haven Standard Clause 1, the written price was $2,840 before anyone lifted a tool.
Crawl Space Encapsulation & Vapor Barrier - Buena Park Home Near Beach Boulevard
This 1962 ranch on a raised foundation had an open dirt crawl with rusted steel vents that let in moisture every time it rained. The floor joists showed surface mold and the fiberglass between them was sagging, useless. We removed the degraded material, treated the joists, sealed all vents, and installed a 20-mil reinforced vapor barrier lapped 6 inches up the piers and sealed at all seams. Relative humidity in the crawl dropped from 78% to 52% within 48 hours. The homeowner received a Documented Photo Record of every stage, including moisture-meter readings.
Spray Foam Insulation - Buena Park Addition Near Los Coyotes Country Club
A 400-square-foot master bedroom addition had been framed for six months with nothing but empty stud bays. The homeowner’s contractor had walked off the job mid-project. We came in to insulate before drywall. Because the walls were still open, we used Icynene closed-cell spray foam at 2 inches for R-21 and an air barrier in one application. The blower-door addition test showed 890 CFM50 leakage through the new shell; after foam, 140 CFM50. Wes Okafor delivered the written scope personally - R-value target, foam density, and the 365-Day Done Right Promise included.
Attic Air Sealing & Blown-In Insulation - Buena Park Tract Home in the San Tract Neighborhood
Built in 1978, this home still had its original R-19 batts, which had settled and pulled away from the eaves. Worse, the top plates and wire penetrations were completely unsealed - you could see daylight through several gaps. We don’t blow insulation over an unsealed attic floor. Our crew spent the first day sealing every penetration with acoustic sealant and fire-rated foam, then blew Owens Corning AttiCat fiberglass to a uniform R-38. The before-and-after blower-door numbers: 4,200 CFM50 down to 2,350 CFM50. The homeowner’s summer cooling bill dropped 23% the following August compared to the prior year.
Radiant Barrier Installation - Buena Park Home Near Gilbert Street
The attic on this 1985 two-story hit 148°F in July afternoons, dumping heat into the second-floor bedrooms through the ductwork that ran through the unconditioned space. The existing insulation was adequate at R-30, but the roof deck radiated heat directly onto it. We installed a perforated radiant barrier foil stapled to the underside of the rafters, which dropped the attic temperature to 112°F on the next 95°F day. Combined with duct insulation wrapping, the second floor held temperature within 2 degrees of the thermostat setpoint. The written price was $1,760, delivered before work started.
Insulation Removal, Cleaning & Rodent Proofing - Buena Park Home Near Orangethorpe Avenue
The homeowner heard scratching for three weeks before calling. Inspection showed extensive roof-rat activity in the attic - compressed trails through the insulation, gnawed wires, and concentrated contamination. We removed all insulation and debris, sanitized the deck with an enzyme treatment, sealed every entry point larger than a quarter inch with steel mesh and copper wool, then blew in new Knauf EcoFill blown-in fiberglass to R-38. The rodent-proofing work carried its own one-year warranty separate from the insulation. Documented Photo Record included 47 images from removal through final blow.
