Fast, Reliable Insulation Removal Across San Jose
Insulation removal in San Jose typically costs $1.50 – $3.00 per square foot, and we can have a crew at most homes within 24 – 48 hours. That’s the short answer. The longer answer depends on what’s in your attic: fiberglass batts, blown-in cellulose, rodent-contaminated material, or a mix. We run removal crews through San Jose every weekday, and our dispatch is coordinated from our San Francisco Bay Area office, so same-week scheduling is the norm rather than the exception.
If you’re dealing with raccoon latrine, rat nesting, or insulation that’s been compressed to the thickness of a bath mat for 40 years, call us at (254) 272-5876. We’ll give you a written price before anyone climbs into your attic, and that number won’t move at the door.
Why Alden Attic Insulation Is San Jose’s Preferred Insulation Removal Company
San Jose homeowners call us because we show up. That’s not a slogan; it’s the most common complaint we hear about the previous contractor. Our team is part of the Garrison Partners family, founded in 2002, and every job in San Jose runs under The Garrison Standard: written prices, written guarantees, and background-checked technicians in uniform who arrive inside the window we gave you.
Our local reputation in San Jose is built on jobs that other companies declined or underbid. Owners tell us about crews that quoted low over the phone, then doubled the number after seeing the attic. That doesn’t happen with us. The price is in your hand before a single tool comes off the truck, and the invoice matches it exactly.
Response time to San Jose neighborhoods like Willow Glen, Cambrian, Alum Rock, and the west side near Stevens Creek Boulevard is typically same-day or next-day for inspection. Full removal scheduling runs 24 – 48 hours out. If your attic has live animal issues, we coordinate with pest control companies you hire separately; once the animals are out, we handle the contaminated material.
Bryce Holloway runs our crews, and he keeps a simple rule: treat every San Jose attic like it’s in your own house. That means full containment, proper disposal, and no shortcuts on sanitizing.
Attic Cleanout in San Jose
Attic cleanout in San Jose means a full removal of old insulation, vacuum extraction of dust and rodent droppings, sanitizing fog where needed, and disposal per Santa Clara County rules. This isn’t a partial job. We take it down to the deck, inspect for wiring damage and air leaks, then prep the space for new insulation.
Homeowners in San Jose need this when they’ve had a rodent or raccoon intrusion, when insulation has flooded or compressed, or when they’re upgrading an older Eichler or ranch home from R-19 to current code levels like R-38 or higher. For a typical 1,200 – 1,600 square foot attic, cleanout removal in San Jose runs $1,800 – $3,400 including disposal and sanitizing. Smaller attics under 900 square feet can fall closer to $1,200 – $1,600.
Attic Removal Process and Timeline
Most San Jose attic removals take four to eight hours from drop cloth setup to final vacuum. We use HEPA-filtered vacuums to keep dust out of the living space, and we seal off the attic hatch before extraction starts. If your home has a return plenum running through the attic, we block and protect it so contaminant dander doesn’t circulate into the rooms below.
You can stay home during removal. Containment is the whole point of a clean job, and our crews set up floor protection from the entry door to the hatch. We haul everything off the same day; nothing sits in your driveway overnight.
Removal Before Rewiring or Remodeling
San Jose homes built in the 1950s and 60s often need rewiring before a new insulation installation. If you’re having knob-and-tube replacement, ceiling light work, or recessed can upgrades done, the insulation has to come out first. We coordinate with electricians in San Jose on schedule, and we can remove only the affected bays or the whole attic depending on the scope.
Crawl Space Cleaning in San Jose
Crawl space cleaning in San Jose means removing old insulation that’s fallen from the floor joists, vacuuming debris and rodent waste, and checking for broken vapor barrier. East San Jose and Alum Rock homes sit on a history of damp crawl spaces, and we see a lot of fiberglass that’s sagged onto the ground and wicked moisture. That material holds smell, and it’s a breeding ground for more problems.
For a crawl space under 1,000 square feet, cleaning and old insulation removal in San Jose typically runs $1,400 – $2,800 depending on access height and contamination level. If the crawl space requires working on your stomach through a 18-inch access, that’s slower work, and we price it accordingly. A written quote means no surprise upcharges for “extra labor” after we start.
Vapor Barrier and Moisture Checks
When we clean a crawl space in San Jose, we inspect the vapor barrier as part of the job. A torn or missing barrier is the reason new insulation fails within a year in East San Jose and Alum Rock homes. If the barrier isn’t fixed first, moisture rises, batts sag, and you’re back to the same problem after one rainy season. We’ll tell you honestly if your crawl space needs barrier work before new insulation goes in.
Failure to address this is the most common reason a San Jose homeowner calls us a second time after another company’s job. We’d rather fix it right the first time and give you the 365-Day Done Right Promise in writing.
Rodent Waste and Odor Removal
Rat and mouse waste in a crawl space is a serious hygiene problem. We remove all contaminated insulation, vacuum the space with HEPA filtration, and apply a hospital-grade sanitizer where waste was present. If you plan to sell a home in San Jose, buyers and inspectors will look at the crawl space. A clean one is worth more than you’d expect.
Trusted Brands We Service in San Jose
We remove and install products from brands homeowners in San Jose actually ask about by name: Owens Corning, Johns Manville, GreenFiber, and Knauf among the full line we work with. When we do a removal, we know what we’re looking at, which means we can tell you if the old fiberglass was R-19, if the blown-in cellulose was a GreenFiber product, or if open-cell foam needs chemical rather than mechanical removal. That matters because the next step depends on the answer.
For replacements, we stock common Johns Manville batts and GreenFiber blown-in product in South Bay warehouses, so we’re never waiting a week for material. If you want to research the replacement insulation before committing, all four of those brands have detailed product literature online.
Common Insulation Removal Problems We See in San Jose Homes
- Raccoon latrine in Willow Glen and Cambrian attics. Mid-century homes with open soffit gaps attract raccoons in early spring. The waste colonies we remove in Willow Glen are consistently among the worst in San Jose because attics stay warm enough for animals to nest year-round.
- Compressed fiberglass in 1950s ranch homes. R-19 batts that have been walked on for decades lose most of their insulating value. Running a conversion from compressed batts to blown-in GreenFiber in San Jose usually drops the heating bill by 20 – 30% the first winter, and we’ve seen it happen enough times to say it plainly.
- Rodent dander recirculating through return plenums. Some San Jose attic cleanout outfits skip the containment step, and dust ends up in the living room through the return vents. That’s a real problem for allergy sufferers in Cambrian and Willow Glen, and it’s avoidable. We block and seal the plenum before vacuum starts.
- Sagging crawl space insulation in East San Jose and Alum Rock. High winter groundwater and heavy clay soil mean crawl spaces stay damp. We see insulation that’s fallen onto the dirt and absorbed moisture, and when that happens, rim joists start to mildew. Cleaning it out has to happen before anything else goes back in.

FAQs About Insulation Removal in San Jose
Most contaminated attic removals in San Jose are scheduled within 24 – 48 hours of your call. We reserve same-day slots for hazardous cases like raccoon latrine where the homeowner can’t safely stay in the house, and we answer the phone live 24/7 so you’re never leaving a message and waiting. Call (254) 272-5876 and we’ll tell you honestly what the schedule looks like.
Yes. Raccoon waste removal requires full PPE, containment sealing, and hospital-grade sanitizer fogging after the material is vacuumed out. Old fiberglass removal without contamination doesn’t need sanitizing. The difference in price in San Jose is roughly $1.00 per square foot, and we’ll tell you which category you’re in before the quote is written. Never let a crew skip the sanitizing step; the odor comes back within weeks.
We remove Owens Corning, Johns Manville, Knauf, CertainTeed, and GreenFiber products regularly, along with older brands that are no longer manufactured. When we remove, we can often tell you what brand and R-value was originally installed, which helps you decide what replacement makes sense. Questions about specific materials? Call us and ask; we’d rather you be informed before the job than surprised after.
Yes, especially in East San Jose and Alum Rock where damp clay soil keeps crawl spaces humid year-round. If old insulation has fallen or wicked moisture, it needs to come out before any new material goes in. We include vapor barrier inspection as part of every crawl space cleaning in San Jose, and we’ll write the repair recommendation into the quote so you know the full picture.
Yes, most single-story homes in San Jose can be fully cleaned and reinsulated in one day. We did exactly that in the Willow Glen scenario above: removed contaminated Owens Corning R-19 batts, sanitized the deck, and blew in new Johns Manville R-38 before the crew left. The only constraint is dry time if sanitizing fog was used, which takes about an hour. Call (254) 272-5876 for a same-day assessment and a written scope.
