Why Alden Attic Insulation Is Morgan Hill’s Preferred Blown In Insulation Company
Alden Attic Insulation operates under The Garrison Standard, the set of rules set by the Garrison Partners family when it was established in 2002. Every job gets a written price before work starts and a written guarantee covering 365 days. If the insulation fails in that window, we return free and fix it. No fine print, no phone tag. The 365-Day Done Right Promise is non-negotiable on every Morgan Hill job.
Morgan Hill homeowners have a particular reason to care about written guarantees: attic work here gets tested hard. Summer heat pushes attic temperatures past 130°F, and poorly installed blow-in will fail visibly within two or three seasons. We install it right the first time because the guarantee is in writing and we’re the ones who have to honor it.
Every technician who walks into a Morgan Hill home is background-checked and arrives in uniform. You’ll know exactly who is on your property before they step inside. And when you call (254) 272-5876, a real person answers, even at 2 a.m. No voicemail, no call-back form.
Cellulose Insulation in Morgan Hill
Cellulose insulation is the most common blown-in material we install in Morgan Hill attics, largely because it handles the dry summer heat better than loose fiberglass in older vented attic designs. If you live in a 1960s ranch near downtown or a hillside home on the west side, you likely have original fiberglass batts that have compacted to a fraction of their original R-value. Cellulose blown in over a properly air-sealed attic floor restores that thermal barrier and keeps conditioned air where it belongs. Most Morgan Hill cellulose jobs run $1,800 to $3,900, including removal of old material where needed.
What the Cellulose Job Involves
We start by inspecting the attic floor for gaps around top plates, can lights, and bath fan housings. Air sealing happens before any material goes in. Then we remove or rake compacted fiberglass batts as needed, pressure-check ventilation, and blow cellulose to the target R-value, usually R-38 to R-49 in Morgan Hill. The material settles slightly, so we over-blow to compensate.
Why Morgan Hill Homeowners Choose Cellulose
Cellulose packs tighter than fiberglass and resists the air movement that happens in vented attics during hot afternoons. It also does a better job of filling odd cavities in older homes, which matters on Morgan Hill’s 1950s and 60s floor plans where joist spacing isn’t uniform.
Blown In Attic Insulation in Morgan Hill
Blown in attic insulation across Morgan Hill homes usually costs between $2,200 and $4,600 for a full job, depending on square footage, current R-value, and whether we need to remove old material first. Attics in this area often have R-11 to R-19 existing insulation when they should have R-49, so the upgrade is significant and the payoff is immediate. We frequently see second-story rooms that won’t cool below 80°F in summer, and the fix is almost always the attic. A complete Blown In Insulation overhaul in Morgan Hill takes one day for most single-story homes, a day and a half for larger two-story ranches.
Removal Before Blowing New Material
If the old fiberglass is compressed, rodent-damaged, or saturated with dust, it has to come out before we blow. We remove it, bag it, and haul it. Then we inspect the decking and trusses for moisture and pest issues before any new material goes in. Skipping this step is what leads to insulation that “stops working” after two summers.
Air Sealing and Ventilation Checks
We pressure-check attic ventilation on every Morgan Hill job. Undersized vents on older ranch plans cause wind-washing at the eaves, which strips cellulose away from the soffit area over time. We install or repair baffles and seal top plates so the blown material stays where it’s put.
Trusted Brands We Service in Morgan Hill
We install and remove insulation using products from Johns Manville, Knauf, Rockwool, CertainTeed, and several other manufacturers. That means you can research exactly what’s going into your Morgan Hill attic before you say yes. We stock local inventory for Morgan Hill jobs, so common materials are ready on the truck and turnaround is fast. Whether you choose Johns Manville fiberglass or GreenFiber cellulose, the brand decision is yours, made with a written price in hand and our recommendation on the table.
Common Blown In Insulation Problems We See in Morgan Hill Homes
- Compacted 1950s – 70s fiberglass batts – Original insulation in Morgan Hill’s downtown and Dunne Avenue homes has settled and shifted, leaving top plates and recessed-can housings exposed. Blowing new material over it without removal traps the gaps and wastes your money.
- Wind-washed cellulose at the eaves – Undersized or clogged soffit baffles on older ranch plans create hot-edge zones where blown-in material gets pushed away from the perimeter. We fix the baffles before we blow.
- Rodent tunneling in hillside attics – Homes on the Santa Teresa side see pest intrusion that channels through loose insulation, destroying R-value. We rodent-proof the perimeter before installing blown-in material, especially on hillside lots near open space.
- Second-story rooms that won’t cool below 80°F – We fielded a call from a homeowner near Dunne Avenue after a heat wave. The original 1968 attic had R-11 batts, compressed and patchy. We removed them, air-sealed, and blew GreenFiber cellulose to R-49. The upstairs dropped into the mid-70s within 36 hours.

FAQs About Blown In Insulation in Morgan Hill
Because the original fiberglass batts underneath it were never removed, and they continue to compact and shift while the new blown material settles around the gaps. Morgan Hill’s hot, dry summers accelerate this by drying out old fiberglass and making it brittle. The fix is removal first, then air sealing, then blowing to R-49. Call (254) 272-5876 and we’ll inspect the attic and tell you exactly what’s happening.
Yes, we dispatch to Morgan Hill same day for urgent calls, and most blown-in attic jobs finish in one day. Two-story homes or jobs needing full removal can take a day and a half. We schedule a specific window, not a four-hour range, and the crew shows up in uniform.
We install both, but cellulose is our default recommendation for Morgan Hill’s older vented attics because it packs tighter and resists wind-washing better in the dry summer heat. You’ll get a written recommendation with your quote, and you decide. Products come from Johns Manville, Knauf, Rockwool, and CertainTeed, among others.
We measure the existing R-value during the estimate visit. Most Morgan Hill homes built between 1955 and 1975 have R-11 to R-19 when they should have R-49 in this climate. We’ll show you the measurement and the target, so you know exactly what you’re paying to achieve.
Yes. The 130°F attic temperatures in summer and the prevalence of raised foundations with open crawlspaces mean we pre-check radiant-barrier sheathing and pressure-check ventilation before blowing anything. Hillside lots on the Santa Teresa side get a rodent-proofing step that flat-land attics don’t need. The install method is tailored to the house, not a template.
