If you need attic cleanup after rodents in Richmond, California (Contra Costa County), Antioch, CA, Martinez, CA or Vallejo, CA, AtticareUSA cleans, seals and reinsulates the attic as one project. You may have found droppings in the insulation or noticed a smell near the attic hatch. Or a pest control company told you the rats are gone, but the attic still needs cleanup and new insulation. Either way, that is the job we do.
At a Glance
- Call one contractor for the whole attic: AtticareUSA handles cleanup, rodent exclusion, air sealing and new insulation as a single project in Richmond, Antioch, Martinez and Vallejo, California.
- Clear live rodents first: if rodents are still active, a licensed pest control provider removes them before our cleanup starts, because we do not trap, bait or exterminate.
- Follow the right order: contaminated insulation and debris come out, the work area is sanitized, and entry points and the attic floor are sealed before anything new goes in.
- Install new insulation last: a new layer over rodent-contaminated insulation leaves the odors and contamination in place.
- Start with a free inspection: our proposal by email lists the fee for each service separately, with no hidden fees.
Who Handles Attic Cleanup After Rodents in Richmond, Antioch, Martinez and Vallejo?
Short answer: AtticareUSA handles the full attic job for homes in Richmond, Antioch, Martinez and Vallejo, California. One licensed contractor does the cleanup, rodent exclusion, air sealing and new insulation as a single project, so the attic work is not split between several companies.
You may already have talked to two or three companies. One does pest control. Another sells insulation. A third offers attic cleaning. Each one handles its own piece, and the gaps fall between them. New insulation can go in before every entry point is sealed. A cleanup can happen without anyone checking how the rodents got in.
We put the whole sequence under one proposal. Our specialty is rodent exclusion (sealing entry points), attic cleanup, sanitation and restoration. You get one inspection, one proposal and one licensed contractor that works through the steps in the right order. Learn more about professional attic cleaning in the Bay Area.
The Pest Control Company Removed the Rats. Who Does the Cleanup?
Short answer: Once a licensed pest control provider has removed the active rodents, AtticareUSA takes over. We remove the contaminated insulation and debris, sanitize the space, seal the entry points and install new insulation. We do not trap, bait or exterminate, so if rodents are still active, pest control comes first.
What pest control covers, and what is left over
Pest control and attic restoration are different trades. A pest control provider deals with the live animals. What stays behind is the attic itself: soiled insulation, nests, droppings, chewed material and the gaps the rodents used to get in. Trapping alone does not address how the rodents entered.
That is why a pest control visit can end with “you still need attic cleanup and new insulation.” The removal is done. The restoration has not started.
Our role is that second part. If rodents are still active when you call, a licensed pest control provider removes them first. Then we do the cleanup, entry-point sealing and insulation.
What stays behind in the insulation
If you’ve seen rodent droppings in your attic, you already know it’s not just a pest problem. It’s a contamination problem. Insulation can hold urine staining, nesting material, droppings and odor that you cannot fully see from the hatch. The insulation is often where the evidence is hiding.
Rodent droppings, urine and nesting materials should be handled with care during cleanup, as the CDC’s guidance on cleaning up after rodents explains [1]. Leftover scent trails matter too, because they can draw new rodents back to the same attic. Our cleanup removes the droppings and nesting material, and the attic can then be sanitized to cut those scent trails.
The Order of Work for Attic Cleaning and Decontamination
Short answer: The order matters. Inspect, protect the home, remove contaminated insulation and debris, sanitize, seal entry points, air seal the attic floor, then install new insulation last. Each step prepares the attic for the next, and new insulation goes in only after the attic is cleaned and sealed.
Here is how an AtticareUSA attic cleanup after rodents moves from start to finish.
Step 1: Inspection and findings
We check the attic for rodent activity and possible entry points, and we report the findings to you. We also look for rodent damage to pipes and electrical wires. Before recommending replacement, we check for rodent infestation, water damage, or old and worn-out insulation. Our estimator measures the space on site, because price depends partly on the attic’s square footage and condition.
What you will see: a clear explanation of what we found and which steps your attic needs.
Step 2: Protecting your home
Before work starts, our crew covers floors in the work area with protective barriers as needed and sets up plastic partition walls or dust-barrier tunnels where required. This protects your living areas while material comes out.
What you will see: covered floors and a contained work path.
Step 3: Removing contaminated insulation and debris
We remove old and contaminated insulation with a heavy-duty vacuum, along with rodent droppings, nests and debris, then haul it away and dispose of it. The cleanup also covers rodent carcasses and rodent waste where present. Once the old insulation is out, we vacuum the remaining droppings, nests and debris from the exposed attic surfaces.
Taking out the old insulation also exposes issues that were buried under it, such as damaged wiring or hidden gaps.
What you will see: a bare, vacuumed attic floor.
Step 4: Sanitizing and deodorizing
Attic cleanup can include treating the work area with OdoBan disinfectant and odor eliminator to address rodent odors and pheromones. Sanitizing can cut the leftover scent trails that draw new rodents back.
What you will see: a treated work area, with deodorizing to address the smell.
Step 5: Sealing rodent entry points
Our rodent proofing is pesticide-free. We seal entry points with wire mesh, polyurethane foam and cement as needed, matched to the size and type of opening. In Bay Area homes, rodents can get in through vents, crawl space openings, roofline gaps, utility penetrations and construction openings, so the inspection checks each of these. Sealing entry points helps reduce the chance of future rodent entry. This step happens before new insulation goes in, because a clean attic can become contaminated again if entry points are left open. See how we approach East Bay rodent proofing services.
What you will see: sealed openings at the places the inspection identified.
Step 6: Air sealing the attic floor
Air sealing closes gaps and cracks around fixtures, piping, wiring and vents on the attic floor with foam and caulk before insulation is installed. When we remove old attic insulation, we seal and caulk the gaps between the attic and living space to comply with California’s Title 24 building code. Air sealing helps reduce uncontrolled air movement between the living space and the attic, and the U.S. Department of Energy’s Building America measure guideline for attic air sealing treats it as work to finish before insulation goes in [2].
What you will see: foam and caulk at penetrations across the attic floor.
Step 7: New insulation, installed last
New insulation goes in last, after cleanup and sealing, and we install it to the depth and R-value your home needs. Insulation is the final layer of a better attic, not the first shortcut. Insulation and air sealing can support comfort and energy efficiency. Read more about attic insulation replacement services.
What you will see: an even layer of new insulation over a clean, sealed attic floor.

Can New Insulation Go Over the Old?
Short answer: Not when the old insulation is rodent-contaminated. Rodent-contaminated insulation is replaced, not topped up, because a new layer on top leaves the odors and contamination in place. Clean, dry insulation that has only settled may be topped up instead of replaced.
Why topping up contaminated insulation does not work
A fresh layer over soiled insulation can look like a quick fix. The problem is still underneath. The droppings, urine staining and nesting debris stay in the attic, and so do the odors. If the entry points are still open, rodents can get back in and contaminate the new layer too.
Do not cover the problem with new insulation. AtticareUSA removes insulation with droppings, urine staining or nesting debris, and insulation that has been chewed or heavily compressed.
When existing insulation can stay
We do not treat every attic as a removal project. We explain what can stay in place. Clean, dry insulation that has only settled may be topped up rather than replaced. When attic insulation has turned dark from filtering dust out of air leaks, we can seal the attic leaks and the insulation may stay in use.
The inspection decides which case your attic falls into. You get the reasoning with the recommendation, so you can see why a step is or is not on the proposal.
