Fast, Reliable Insulation Removal Across Kensington
Kensington homeowners call us when attic insulation has failed. In this town, that usually means moisture, not just age. The fog that rolls up the east slope of the Berkeley Hills settles into attics off Amito Drive, Sunset Drive, and Upper Kensington Road, and over years it quietly destroys what was once good insulation. Our crews run same-day service into Kensington from our Bay Area dispatch office, and we always answer the phone live, 24/7. Call (254) 272-5876 and you’ll talk to a person who can schedule you inside a real window, not a half-day range.
Typical full insulation removal in Kensington runs $1,500 to $3,800 depending on square footage, attic access, and what’s actually up there. You get a written price before we touch anything. The number on the invoice matches the number you approved.
Why Alden Attic Insulation Is Kensington’s Preferred Insulation Removal Company
Alden Attic Insulation is independently owned and operated, held to The Garrison Standard. That means written prices, written guarantees, and a background-checked, uniformed crew that arrives inside the scheduled window. Every technician on a Kensington job has passed a background check, and every job carries the 365-Day Done Right Promise: if the removal or the new insulation fails within a full year, we come back and make it right at no charge. In writing.
Kensington homeowners regularly tell us the same thing: they’ve been burned by crews that no-showed or found a way to raise the price after the truck was already parked in the driveway. That doesn’t happen with us. The Garrison Code applies on Amito Drive, Purdue Avenue, and every other street in Kensington the same way it applies on every Alden job. Written estimate first. Written guarantee after.
We know this town’s housing stock. Kensington’s hillside homes range from 1940s bungalows to 1970s ranchers and custom builds tucked into the slope, and the attics vary just as much. Some have real access stairs, some have a scuttle hole in a hallway ceiling, and some have almost no clearance at all. That local familiarity means we show up with the right equipment the first time.
Attic Restoration in Kensington
Attic Restoration in Kensington means more than pulling old insulation out. The fog-belt moisture pattern off the east slope of the hills means attics here hold humidity that flatland attics in Berkeley or Albany simply don’t. So a proper restoration job in Kensington starts with a full assessment of why the old insulation failed, then removal, cleaning, and treatment of the deck before anything new goes in.
Homeowners call us for attic restoration after a roof leak, after rodents have nested for years, or when blown-in insulation has matted down and stopped holding an R-value worth paying for. In Kensington’s hillside homes, we also see restoration work needed after fog-driven moisture has saturated old batts and compressed them flat. That’s a Kensington-specific failure. The insulation looks tired but not catastrophic, and underneath it the roof deck is quietly rotting.
A full attic restoration with removal, HEPA vacuum, air sealing, and new blown-in insulation typically runs $3,200 to $6,500 in Kensington depending on square footage and what we find under the old material. Free estimate, written price before any tool comes off the truck.
Moisture-Failed Batt Removal
When Owens Corning or Johns Manville fiberglass batts have been wet, they mat down and lose their loft. R-value drops. In Kensington, the morning fog off the bay and afternoon sun cycle bakes moisture into the attic, and older batts hold it. We pull the failed material, HEPA-vacuum the bays, and inspect the deck before you spend a dollar on new insulation.
Post-Rodent Attic Reset
Rodent activity in Kensington attics is common. The hills, the trees, the older construction. Droppings, urine, and nesting contaminate insulation in ways you can’t see from the scuttle hole. Proper restoration removes every bit of the old material, sanitizes the bays, and leaves the attic clean enough to inspect before insulation goes back in.
Attic Cleanout in Kensington
Attic Cleanout in Kensington is the right call when the insulation is compromised beyond saving. Whether it’s saturated fiberglass, rodent-contaminated cellulose, or blown-in material that’s settled to half its original depth, the solution is the same: remove everything, clean the space, and start fresh. In this town, that’s especially true on the hillside streets where fog moisture keeps cycling through attics year after year.
A cleanout typically runs $1,500 to $3,800 in Kensington. The range depends mostly on square footage, access, and whether there’s contamination. Rodent waste, mold, or old blown-in material that’s packed down changes the labor involved, and that’s reflected honestly in the written estimate before work starts. Not after.
Contaminated Insulation Removal
When rodents have lived in an attic, the insulation isn’t just dirty. It’s contaminated. And skimming the top layer off with a rake doesn’t solve it. The tunnels and nesting are down in the bays, against the ceiling. We remove it all, HEPA-vacuum the deck, and kill the odor at the source. Kensington’s older homes often have decades of rodent traffic in the attic, and a surface-level cleanup leaves the problem right where it was.
HEPA Dust Control During Removal
Removing insulation without a HEPA vacuum and negative air setup sends fiberglass dust through the house. Kensington’s older HVAC systems often have return ducts in the hallway or ceiling that pull attic air and dust right back into the living space. That’s a common call we get after a weekend DIY attempt went sideways. Our cleanout runs with HEPA filtration and negative air, so the mess stays in the attic, not the living room.
Trusted Brands We Service in Kensington
We remove and reinstall insulation made by brands Kensington homeowners can research on their own before saying yes: Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber. That matters because the material in your attic is a long-term investment, and you should know exactly what it is before anyone installs it. If an old Kensington attic has failed Owens Corning batts, we’ll tell you that’s what we found. If it’s rodent-contaminated GreenFiber that needs to come out, we’ll tell you that too. No vague language. Specific brand, specific condition, specific fix.
Common Insulation Removal Problems We See in Kensington Homes
- Fog-driven attic moisture. The same hillside microclimates that keep Kensington’s gardens green destroy attic insulation. Morning fog off the bay saturates the underlayment, afternoon heat bakes it into the older fiberglass, and you end up with soggy, matted batts failing long before they look dirty.
- Rodent-damaged blown-in insulation. Old GreenFiber or cellulose hides tunnels and nesting under the surface fluff. If removal stops at the visible layer, the contamination stays in the bays. Kensington’s dense tree cover and older housing stock keep rodents active year-round.
- Settled, compressed batt insulation. Legacy Owens Corning and Johns Manville batts from the 1970s and 1980s lose loft and R-value over decades. In Kensington’s hillside homes, that compression happens faster because of the moisture cycle. The insulation looks fine on top and fails underneath.
- DIY removal dust contamination. We get calls from Kensington homeowners who tried to remove old insulation themselves without HEPA filtration. Fiberglass dust gets into the HVAC return, and now the whole house itches. It’s dangerous work in tight, hot attics. Leave it to a trained crew with the right equipment.

FAQs About Insulation Removal in Kensington
Why does insulation removal in Kensington’s hills feel different from nearby flatland cities?
Kensington’s hillside microclimates off Amito Drive and Sunset Drive create a fog-driven moisture cycle that flatland cities like Albany or western Berkeley don’t have. Morning fog wets the roof underlayment, afternoon heat bakes that moisture into the insulation, and fiberglass batts mat and fail from the inside out. Removal here often means pulling soaked, compressed Owens Corning or Johns Manville batts before they rot the roof deck, a failure pattern that shows up far less in flatter, hotter inland cities. Call (254) 272-5876 and we’ll tell you honestly whether your attic has this problem.
Can you really do same-day insulation removal in Kensington?
Yes. We run same-day service into Kensington and schedule inside a real window, not a half-day range. If the job is urgent, like water-damaged insulation actively dampening the ceiling below, call (254) 272-5876 in the morning and we can typically have a crew there that day. Background-checked, uniformed technicians, written price before any work starts.
How do I know if my old Owens Corning or Johns Manville batts need removal vs. just topping off?
If the batts are wet, matted, or have been home to rodents, they need removal, not topping off. Adding new insulation over failed material buries the problem and speeds up rot in the deck. In Kensington’s fog belt, batts that have been through even one or two moisture cycles compress and lose most of their R-value. If you’re unsure, call (254) 272-5876 for an assessment. We’ll tell you honestly if removal is necessary, and the estimate is free.
What happens to rodent-contaminated GreenFiber or cellulose in a Kensington attic?
It all comes out. Contaminated GreenFiber or cellulose can’t be treated in place. The tunnels and nesting sit deep in the bays, and any material left behind keeps the odor and the health risk. We remove everything, HEPA-vacuum the deck, sanitize, and leave the attic clean before new insulation goes in. Call (254) 272-5876 for a written price on a full contaminated-insulation removal.
After removal, what insulation brands can you reinstall in Kensington?
We install Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber. After removal, we’ll recommend the right material for your attic’s specific conditions: Kensington’s hillside moisture pattern, your current R-value, and your budget. The recommendation is specific and written, and you can research every brand before you sign anything.
