Fast, Reliable Insulation Removal Across Martinez
Most insulation removal jobs in Martinez run $1.50 to $3.00 per square foot, so a typical 1,200-square-foot attic costs between $1,800 and $3,600. We get crews out to Martinez neighborhoods like downtown, the Alhambra Valley, and Virginia Hills the same day you call. If you’re dealing with a wet, sagging attic or a crawl space holding a stale odor, call (254) 272-5876 for a written quote before any work starts.
Martinez has a specific problem other Bay Area cities don’t share. The 94553 ZIP runs directly alongside the Shell/Martinez Refining Company corridor, which means attic and crawl space insulation here absorbs petrochemical soot and an aromatic-hydrocarbon odor. You don’t air-seal over that. It has to come out first. That’s the work we do, and it’s the reason we treat removal as its own trade, not a warm-up for installation.
Why Alden Attic Insulation Is Martinez’s Preferred Insulation Removal Company
We’re part of the Garrison Partners family, established 2002, and every Martinez job runs under The Garrison Standard: a written price before work begins and a written guarantee good for 365 days. Bryce Holloway, our owner, holds each crew to that standard on every removal, from a tight downtown attic to a sprawling Alhambra Valley rancher.
Our technicians are background-checked and uniformed. They show up inside the scheduled window, not a six-hour range. Martinez homeowners call our office and a live person answers, 24/7. That matters when you’ve got a damp attic above you or a crawl space smell seeping through the subfloor and you need to know someone is actually coming.
We know the difference between a Martinez bungalow built in the 1920s near Main Street and a 1980s hillside home off Alhambra Avenue. That changes how we approach removal, how we protect your ceiling during the job, and what R-value we recommend for the replacement. The 365-Day Done Right Promise covers every removal we do here: if the work fails within a year, we come back free and make it right.
Crawl Space Cleaning in Martinez
Crawl Space Cleaning in Martinez is not optional when the old insulation has to come out, especially in the neighborhoods west of downtown near the refinery. The crawl space under an older Martinez home traps petrochemical odor in the soil and in debris, so pulling the insulation without cleaning the crawl space means the smell comes right back through the subfloor within a week.
A typical crawl space cleaning in Martinez runs $1,200 to $2,400 depending on square footage, access height, and how much debris and old insulation has to be bagged out. If the vapor barrier is torn or missing, that’s additional material and labor, and we’ll include it in the written quote before the crew starts. No number moves after you approve it.
Odor Source Removal, Not Masking
The goal is to get the floor cavity back to bare soil and clean framing, then lay a new vapor barrier over it. We bag and haul contaminated debris out of the crawl access, HEPA-vacuum the rim joists, and leave the space dry and ventilated. If the odor source was the old saturated insulation, the basement air is noticeably different the same afternoon.
When Crawl Space Cleaning Precedes New Insulation
We always sequence crawl space cleaning before new insulation goes in. A homeowner who skips this step and re-insulates over a contaminated crawl space is paying twice. The odor and moisture cycle repeats, and the new insulation fails early. Our crews check this before quoting so you know what the full scope looks like from day one.
Attic Insulation Replacement in Martinez
Attic Insulation Replacement in Martinez almost always starts with Martinez Blown In Insulation removal, since new material can’t go over what’s already up there. Old fiberglass batts in Martinez attics wick moisture from the Delta fog and winter rain, then sag and compress against the eaves. Once the batts collapse, they stop insulating and start holding water. That’s when a homeowner notices the upstairs rooms won’t hold temperature and there’s a musty, sometimes oily smell by the attic hatch.
A full attic insulation removal and replacement in Martinez runs $2,200 to $4,800 for a standard 1,200 to 1,600-square-foot attic. The spread comes down to attic depth, how much old material has to be bagged out, and what R-value we’re replacing it with. We write every one of those numbers down before the job starts.
Removal to Bare Decking
We take Martinez attics down to the bare decking, HEPA-vacuum the joist bays, and check for air leaks along the top plates and light penetrations. Skimming this step or leaving a layer of damp, smelly insulation under new batts means the new insulation inherits the same problem. That’s why our Insulation Removal team treats this as a complete process, not a partial clean-up.
Replacement R-Value Selection
For Martinez attics we typically replace at R-38 to R-49, matching the existing joist depth or bringing it up to current Bay Area energy standards. We stock Owens Corning and Rockwool for replacement jobs so homeowners can research the exact product before saying yes. The written quote names the brand, the R-value, and the square footage.
Trusted Brands We Service in Martinez
We remove and install insulation from Owens Corning, Johns Manville, Knauf, and Rockwool, among others. That matters in Martinez because old attics here often hold a mix of fiberglass batts from different decades, and identifying what’s up there tells us how to handle it. We keep Owens Corning and Rockwool product in stock for Martinez replacement jobs, so the removal-to-install sequence doesn’t stall waiting on material. You can look up any brand we quote before you commit.
Common Insulation Removal Problems We See in Martinez Homes
- The refinery-corridor odor problem. Homes in 94553 west of downtown absorb petrochemical soot into attic and crawl space insulation over years. Removal is the only fix; air sealing alone traps the smell inside the assembly.
- Delta fog moisture in attics. Winter fog and rain drive moisture into old batts, especially in single-story ranchers. Wet batts sag, compress, and rust ceiling fixtures from behind, so the removal has to go to bare decking or the new insulation inherits the wet base.
- Crawl spaces that hold the smell. Older Martinez homes near the refinery corridor trap odor in crawl space soil and debris. Skipping crawl space cleaning during removal guarantees the smell returns through the subfloor, even with new insulation above.
- Same-day removal-and-replace requests near Amtrak and downtown. Homeowners ask for a one-day tear-out and replacement, which only works if the crew pre-orders the right R-value. We quote the attic depth on the first visit and bring the correct Owens Corning or Rockwool product the day we start.

FAQs About Insulation Removal in Martinez
The odor comes from years of petrochemical soot and aromatic hydrocarbons absorbed into attic and crawl space insulation from the Shell/Martinez Refining Company corridor in the 94553 ZIP. When you pull that insulation, the trapped odor releases all at once. That’s why removal has to include cleanup of the decking or crawl space soil before new material goes in. Call (254) 272-5876 and we’ll explain what your specific attic likely holds.
We can usually complete a full attic removal and replacement in Martinez within one to two days, and same-day removal is available if you call before noon. Same-day replace-only jobs fail when the crew doesn’t pre-order the right R-value, so we quote the attic depth on the first visit and bring the correct Owens Corning or Rockwool product when we start.
Yes, if the crawl space holds petrochemical odor in the soil or debris, which is common west of downtown near the refinery. Skipping crawl space cleaning means the smell returns through the subfloor even with new insulation above. We always check the crawl space before quoting so the scope is complete from day one, not discovered halfway through.
We remove and haul away fiberglass batts from Owens Corning, Johns Manville, Knauf, and others, then replace with Owens Corning or Rockwool at whatever R-value matches your attic depth. The written quote names the exact product, so you can research it before approving. We never use a brand we won’t name in writing.
Sometimes, but not when the old insulation is wet, compacted, or carrying the refinery-corridor odor. Leaving damp or contaminated material under new batts transfers the problem to the new insulation. If your attic insulation is dry and intact, topping off may work; if it’s sagging against the eaves, removal to bare decking is the only correct fix. Call (254) 272-5876 for a straight answer on your attic, no charge for the inspection.
