Insulation Before & After in Morgan Hill, CA
Photos don’t lie. A blower-door test gives you a number, and a photo record shows you how we got there. Below are recent building-envelope jobs we’ve completed in Morgan Hill and the surrounding Santa Clara Valley. Each entry includes the problem we found, the work we performed, and the measurable result the homeowner received in writing.

Attic Insulation Removal and Replacement - 1970s Ranch Near Downtown Morgan Hill
The homeowner on West Edmundson Avenue called after a home energy audit flagged temperature swings between the living room and the back bedrooms. We found 6 inches of compressed original fiberglass, no air sealing at the top plates, and eleven recessed can lights with unsealed housings leaking conditioned air straight into the attic. We removed the old material, sealed every penetration with fire-rated caulk and rigid foam, then blew in new Owens Corning fiberglass to R-38. The blower-door test read 3,800 CFM50 before sealing and 2,100 after. The written scope, the photo record, and both blower-door numbers were delivered before we left.
Crawl Space Encapsulation and Vapor Barrier - Home Near Anderson Lake
This home off Watsonville Road sits in the zone where Morgan Hill’s clay-heavy soil holds moisture well into spring. The crawl space had exposed dirt, fallen fiberglass batts trapping water against the joists, and a musty smell that pushed up through the floor registers. We removed the wet batts, graded the soil, installed a 6-mil reinforced polyethylene vapor barrier with sealed seams and taped piers, and sealed the perimeter rim joists with closed-cell spray foam. The relative humidity in the crawl space dropped from 78% to 52% within 48 hours. We documented the moisture readings and the sealed barrier in the photo record, and the homeowner received the written scope with the 365-Day Done Right Promise before we packed up.
Spray Foam Insulation - Bonus Room Over Garage in Paradise Valley
The bonus room over a three-car garage in Paradise Valley was unusable from June through September. The floor was cold in winter and radiated heat upward in summer because the garage ceiling below had no insulation and the kneewalls were open to the vented attic. We sprayed Icynene open-cell foam at R-21 in the kneewalls and the sloped ceiling, and dense-packed the garage ceiling with Rockwool to break the thermal bridge. The surface temperature of the bonus room floor measured 64 degrees in January before the work and 71 degrees after. The homeowner got the before-and-after infrared images in the photo record, plus the written price and scope under Haven Standard Clause 1 before we started.
Attic Air Sealing With Radiant Barrier - Single-Story Near San Martin
A homeowner near the San Martin border was running the AC from 10 a.m. through sunset in July despite having R-30 fiberglass on the attic floor. We found a continuous gap at the top plates where the drywall didn’t meet the plate tight, dozens of unsealed wire and plumbing penetrations, and no radiant barrier. We sealed every gap with acoustic sealant and rigid foam, then laid OSB radiant barrier decking over the existing insulation to reflect summer attic heat. The attic temperature at 3 p.m. in August dropped from 148 degrees to 112 degrees. The blower-door reading went from 4,200 CFM50 to 2,600. The photo record shows every sealed penetration, and the written scope documents the 365-Day Done Right Promise.
Insulation Removal After Rodent Damage - Home Near Morgan Hill Community Park
The homeowner near Morgan Hill Community Park heard scratching in the ceiling for three weeks before finding a roof rat entry point where a palm frond had damaged the fascia. We removed all contaminated insulation, HEPA-vacuumed the entire attic deck, sanitized with an enzyme treatment, sealed the entry point and three others we found, repaired the chewed flex duct with new R-8 insulated line, and blew in new GreenFiber cellulose to R-38. The photo record includes images of every sealed entry, the new duct run, and the depth gauge showing uniform R-38 coverage. Written scope, written warranty, and the 365-Day Done Right Promise were delivered before the first bag of cellulose went up.
Wall Insulation With Blown-In Cellulose - 1960s Home Near Tennant Station
This home near Tennant Station was built in 1964 with empty 2×4 walls. The owner had replaced the windows but still felt drafts along the baseboards in winter. We drilled 2-inch access holes at stud bay spacing from the exterior, dense-packed each cavity with GreenFiber cellulose to R-13 at 3.5 pounds per cubic foot, and sealed the holes with color-matched plugs. A thermal imaging scan before the work showed 14-degree temperature differentials on the exterior walls; after, the differential was under 3 degrees. The photo record includes the thermal images, the access hole pattern, and the filled cavity verification. The written price and scope were delivered under Haven Standard Clause 1, and the blower-door reading improved from 3,400 to 2,400 CFM50.
