Why Alden Attic Insulation Is Mountain View’s Preferred Blown In Insulation Company
Mountain View homeowners rarely call us because nothing’s wrong. They call because a bedroom runs ten degrees hotter than the hallway, or the furnace runs constantly while the PG&E bill climbs, or a previous contractor left the attic half-finished. We show up, assess the actual insulation level, and give you a written price. That number does not change at the door.
Every technician who walks into your Mountain View home is background-checked and in uniform. They arrive inside the scheduled window, not a vague half-day range. And every job carries the 365-Day Done Right Promise: if the insulation work fails within a year, we return at no charge, in writing.

Blown In Insulation Contractors in Mountain View
Blown In Insulation Contractors in Mountain View do more than run a hose into an attic. The job starts with measuring what’s already there, checking the existing R-value, and identifying where air is leaking. Then comes the actual blow: loose-fill fiberglass or cellulose blown to the correct depth, usually R-38 to R-49 for Mountain View attics, with careful attention paid to soffit vents, can lights, and the attic hatch. A typical Mountain View blown-in job takes four to six hours for a 1,200 to 1,800 square foot home, and costs between $1,800 and $4,800 depending on square footage, current R-value, and whether air sealing is included.
What the job actually involves
We start with an attic inspection, checking for old wiring, recessed light housings, and vent baffles that need to stay clear. Then we blow the material to the specified depth and verify coverage with a depth gauge. The crew leaves the attic cleaner than they found it, and you get a written invoice that matches the written estimate.
Air sealing and prep work
Blown-in insulation only works if the air leaks are addressed first. In Mountain View homes, those leaks are typically around the attic hatch, plumbing vents, and where interior walls meet the ceiling. We seal those with foam or caulk before any insulation goes in, a step many contractors skip.
Cellulose Insulation in Mountain View
Cellulose Insulation in Mountain View is one of the most common materials we install, and for good reason. It’s dense, it fills odd-shaped cavities well, and it resists air movement better than blown fiberglass. GreenFiber cellulose is a brand we use regularly on Mountain View jobs. For a 1,500 square foot home, cellulose blown to R-49 costs roughly $2,800 to $4,200, including prep and cleaning. Cellulose has a higher installed R-value per inch than blown fiberglass, around 3.4 to 3.8 per inch, which matters in tight Mountain View attics where there isn’t room for sixteen inches of material.
Why we use GreenFiber cellulose
GreenFiber is made from recycled paper treated with borate for fire and pest resistance. It settles into corners and around cross-bracing better than loose fiberglass. We use it regularly on Mountain View attics with odd rooflines and tight ceiling cavities, including mid-century homes in Monta Loma and Martens-Carmelita.
Cellulose repair and top-up
Cellulose settles over time, especially in older Mountain View homes where it was blown decades ago. If your cellulose has dropped below R-19, we can top it up with additional GreenFiber material without removing the old insulation. That’s usually a half-day job and costs between $1,200 and $2,800 depending on the attic size.
Trusted Brands We Service in Mountain View
We install and remove insulation using products from Owens Corning, Johns Manville, Knauf, and GreenFiber, among others. You can look up any of those brands before we even step in the door. For Mountain View attics, we commonly stock GreenFiber cellulose and Owens Corning blown fiberglass locally, so turnaround is fast. If your existing insulation is Johns Manville or Knauf and needs a top-up, we match the material as closely as possible to keep the R-value consistent. We keep enough material on hand to cover most Mountain View jobs without a second trip.
Common Blown In Insulation Problems We See in Mountain View Homes
- Settled loose-fill in Monta Loma and other mid-century neighborhoods. Insulation blown in the 1960s and 70s has compressed to two or three inches, leaving top plates and recessed lights exposed. That’s a direct thermal bridge into the attic, and it shows up as drafts along exterior walls.
- Improper blocking around attic vents and recessed can lights. Original 1950s construction often has old-style can lights that leak air and can’t be safely covered with insulation. We install proper IC-rated housings or build dams around them before blowing anything.
- Compressed insulation from HVAC or electrical work. Tight attics in Mountain View’s older homes make attic work cramped. Technicians crawl through, and the insulation gets trampled. We re-fluff or top up the compressed areas to restore the R-value.
- The local permit and inspection variable. Mountain View’s building permit and energy-upgrade requirements are stricter than surrounding cities. A blown-in insulation job here can require a HERS verification or city inspection that isn’t standard in neighboring Palo Alto or Sunnyvale. We handle that paperwork and schedule the inspections as part of the job.

FAQs About Blown In Insulation in Mountain View
Mountain View’s building code requires a permit for most attic insulation work, especially when air sealing or modifying attic access is involved. We handle the permit application, schedule any city inspections, and coordinate HERS verification when the project triggers Mountain View’s energy-upgrade requirements. Call (254) 272-5876 and we’ll check your specific address.
We typically schedule Mountain View insulation calls within 24 to 48 hours. Emergency situations, where insulation has been damaged by a roof leak or pest intrusion, can often be same-day. A live person answers the phone 24/7, so you’ll get a real human when you call.
The most common problem is settled loose-fill in mid-century homes around Monta Loma and other 1950s and 60s tracts. Insulation that was originally blown to R-30 has compressed over decades to R-11 or less. That’s a repairable condition: we re-fluff the old material or top it up to current code.
We install both, and the choice depends on your attic. Cellulose, usually GreenFiber, works well in tight, irregular attics because it fills cavities and resists air movement. Fiberglass, usually Owens Corning, is lighter and often preferred where existing material is fiberglass. We’ll tell you which one suits your attic and why.
Yes. When an electrician, plumber, or HVAC tech moves insulation aside and doesn’t put it back, we re-fluff the compressed areas and top up where it’s thinned. A repair like that is usually a half-day job, running $600 to $1,500 depending on how much area was disturbed. Call (254) 272-5876 for an exact quote.
