Sacramento attic cleanup after rodents usually comes down to five steps done in one order: inspect the attic, remove the contaminated insulation and waste, sanitize the exposed space when needed, seal the entry points, then install new insulation on a clean, sealed attic floor. AtticareUSA does all five as one project under one licensed contractor (CA #1051462). If rodents are still active, a licensed pest control provider removes them first.
At a glance
- Clear live rodents first: a licensed pest control provider removes active rodents, and we take over from there.
- Clean before anything new goes in: Cleanup starts with removing contaminated insulation and waste, then sanitizing the exposed space when needed.
- Seal the way back in: entry points and attic floor gaps are sealed before insulation, and the rodent proofing carries a 1-year warranty with no subscription.
- Insulate last: new insulation goes on a clean, sealed attic floor, to the R-value the home needs.
- Compare written proposals: a free inspection, or an estimate by email, with each service priced separately.
The Short Answer: Who Handles the Whole Project in Sacramento
AtticareUSA handles attic cleanup, decontamination, rodent entry-point sealing, air sealing and new insulation as a single project for Sacramento homeowners. Live rodents are handled first by a licensed pest control provider; we then clean, seal and restore the attic.
If you found droppings in the insulation, smelled something stale at the attic hatch, or heard scratching overhead at night, this is more than a pest problem. It is a contamination problem, and the insulation is often where the evidence is hiding.
When cleanup, sealing and insulation are split across different companies, each of them sees only part of the attic. The gaps between their scopes are where problems survive. A rodent hole nobody was paid to seal stays open. Droppings nobody was paid to remove end up buried under new insulation.
We are built for the full attic restoration:
- Cleanup and decontamination: removal of old or contaminated insulation, droppings, nests, carcasses and debris, with haul-away and disposal.
- Rodent proofing and exclusion: sealing entry points with wire mesh, polyurethane foam and cement as needed. The work is pesticide-free.
- Air sealing: closing gaps around fixtures, piping, wiring and vents on the attic floor before insulation goes in.
- New insulation: installed last, to the depth and R-value the home needs.
We have been in business since 2012, have helped over 11,000 clients, and are highly rated with 1400+ reviews. We are Diamond Certified, BPI-certified, and licensed, insured and bonded (CA #1051462).
Why the Order of Sacramento Attic Cleanup Matters
The order matters because each step makes the next one possible. Removing the insulation exposes the entry points and damage hidden underneath, cleaning has to happen before anything new goes in, and new insulation only lasts if the attic under it is clean and sealed.
New insulation should not be installed over an unresolved rodent or contamination problem. A fresh layer on top leaves the odors and contamination in place, and if the entry points are still open, rodents can move straight back into clean, new material. Here is the sequence, and what each step does for you.
Step 1: Inspect the attic and protect the home
The first step is finding out what is actually up there. Our inspection checks the attic for rodent activity, possible entry points, rodent damage, and damage to pipes and electrical wires. We also check how well the existing insulation is working, and our technicians use a thermal imaging camera to find drafts and heat loss. We report the findings to you.
When the job starts, our crew protects the home first. Floors in the work area are covered with protective barriers as needed, and plastic partition walls or dust-barrier tunnels go up where required. The mess stays in the attic, and it leaves with us.
Step 2: Remove the contaminated insulation and waste
We remove rodent-contaminated insulation with a heavy-duty vacuum, along with droppings, nests and debris, then haul it away for disposal. Once the old insulation is out, we vacuum the remaining droppings, nests and debris from the exposed attic surfaces.
Rodent waste needs careful handling. CDC guidance for homeowners cleaning up after rodents is not to sweep or vacuum urine, droppings or nests, because that can put particles into the air, and to wet them with a disinfectant first (CDC). That guidance is written for homeowners, and it is one reason this part of the job belongs to a trained crew with containment and heavy-duty equipment, not a weekend DIY project.
Removal is also when the hidden problems show up. With the attic floor bare, we can see the gaps, chewed wiring and other damage the old insulation was covering.
Step 3: Sanitize the exposed space
With the attic floor bare, we can treat the work area with OdoBan disinfectant and odor eliminator to address rodent odors and pheromones. We offer sanitation when it is appropriate for the space. It matters because rodents follow scent trails, and cutting those leftover trails removes one of the signals that draws new rodents back.
Step 4: Seal the entry points and air seal the attic floor
Rodent proofing is the step that keeps the clean attic clean. We seal entry points with wire mesh, polyurethane foam and cement as needed, matched to the opening: roofline gaps, vents, utility penetrations and construction openings. Sealing entry points helps reduce the chance of future rodent entry. A clean attic can become contaminated again if entry points are left open, so the job is not complete until the path back in has been addressed.
In the same pass, we air seal the attic floor, closing gaps and cracks around fixtures, piping, wiring and vents with foam and caulk. ENERGY STAR guidance is to seal attic air leaks before adding insulation (ENERGY STAR), and a bare attic floor makes those gaps easy to reach.
Step 5: Install new insulation on a clean, sealed deck
New insulation goes in last, after cleanup and sealing, to the depth and R-value the home needs. Depending on the attic, that can be fiberglass batts or blown-in insulation. Insulation and air sealing together can support comfort and energy efficiency, but only when the attic underneath is ready for them. Insulation is the final layer of a better attic, not the first shortcut.
For a deeper look at the method, see our attic cleanup order of operations and the 5-step attic restoration process.
When Insulation Has to Come Out, and When It Can Stay
Insulation with droppings, urine staining or nesting debris comes out, and so does insulation that has been chewed or heavily compressed. Clean, dry insulation that has only settled may be topped up instead.
Not every attic is a removal project. AtticareUSA explains which steps your space actually needs (insulation removal, sanitization, rodent proofing, air sealing) and works out the approach with you. As a rule of thumb:
- Usually removed: insulation with droppings, urine staining, nesting debris, chewing damage or heavy compression.
- May stay in place: clean, dry insulation that has only settled, which can be topped up rather than replaced.
- Needs a fix first: wet insulation is replaced only after the moisture source is fixed.
If we spot moisture signs during the inspection, the source has to be fixed before wet insulation is replaced. Suspicious materials may need evaluation by a specialist before work continues.
Pest Control vs. Restoration: Who Does What
A licensed pest control provider removes live rodents. AtticareUSA does not trap or remove live rodents; we clean the attic, sanitize it when needed, seal the entry points and install new insulation.
This split is the clearest way to avoid paying for half a job. Trapping alone does not address how the rodents got in, and it does not remove the insulation they contaminated. Restoration without dealing with active rodents does not hold either. So the work happens in this order:
- If rodents are still active: a licensed pest control provider removes them.
- Then we take over: inspection, removal of contaminated insulation and waste, sanitation, entry-point sealing, air sealing and new insulation.
Because our role is exclusion and restoration, the fix is one-time rather than ongoing. There is no monthly visit schedule to keep the protection in place. Read more about how our rodent proofing and exclusion work.
What a Complete Written Proposal Should List
A complete proposal for attic cleanup after rodents lists each part of the job and its fee separately: inspection findings, home protection, removal and disposal, sanitation, entry-point sealing, air sealing, new insulation with a stated R-value, and the terms of any rodent-proofing warranty.
Use this checklist to compare the quotes you receive:
- Inspection findings: what was found, including rodent activity, entry points and damage.
- Home protection: floor coverings, plastic partitions or dust-barrier tunnels where needed.
- Insulation removal: the area to be cleared, measured in square feet.
- Waste removal: vacuuming of droppings, nests, carcasses and debris from the exposed surfaces.
- Haul-away and disposal: where the removed material goes.
- Sanitation and deodorizing: whether the work area will be treated, and with what.
- Entry-point sealing: where the openings are and what materials will close them.
- Air sealing: the gaps around fixtures, piping, wiring and vents on the attic floor.
- New insulation: material type, depth and R-value.
- Warranty: what the rodent-proofing warranty covers and for how long.
AtticareUSA sends a transparent proposal by email with exact prices and service details, and each service is listed with its own fee. There are no hidden charges or upfront fees. Price depends partly on the square footage of the attic, plus its condition and any added issues you choose to fix, which is why our on-site estimator takes measurements. We can also send an estimate without an in-person inspection. If you already have another contractor’s quote, we offer a free second-opinion inspection and a written proposal you can compare side by side.
Two Completed Sacramento Jobs
AtticareUSA has completed full attic cleanup and reinsulation projects in Sacramento, including a 932 sq ft attic in 95821 taken from severe rodent activity to new R-38 insulation.
Proof matters more than badges when you are choosing someone to work above your ceiling. Here is what two of our Sacramento attic cleanup jobs looked like.
Sacramento 95821: severe rodent activity to R-38
This attic had severe rodent activity. Our crew:
- Removed 932 sq ft of insulation with a heavy-duty vacuum, down to bare joists.
- Vacuumed out the rodent waste and nesting material.
- Treated the surfaces with OdoBan sanitation.
- Sealed the entry points with wire mesh, polyurethane foam and cement.
- Air sealed the gaps around fixtures, piping, wiring and vents.
- Installed new R-38 fiberglass batts.
That is the full sequence from this guide, done in order on one Sacramento home. See the 95821 project.
Sacramento 95816: underperforming insulation replaced
In this attic, the existing insulation was below R-19. With plastic coverings up and our crew in protective gear, we vacuumed out the old insulation and replaced it with blown-in insulation. See the 95816 project.
Before-and-after photos are available upon request, so you can see your attic before and after the work.
The 1-Year Rodent-Proofing Warranty
AtticareUSA’s rodent proofing carries a written 1-year limited warranty on the treated areas. It is a one-time, subscription-free fix, unlike an exterminator’s recurring service contract.
Here is what the warranty covers:
- What is covered: the treated areas. Living spaces and garages are not included.
- New entry points: new rodent entry points found within the year are sealed at no additional charge, subject to the listed exclusions.
- If you sell: the warranty transfers to the next owner.
The warranty covers the rodent proofing, not the cleanup or insulation work. It protects the step that keeps the rest of the project clean, and you do not need to stay on a service plan to keep it.
Frequently Asked Questions
Can I put new insulation over old insulation after rodents?
Not when the old insulation is 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.
Does AtticareUSA trap or remove live rodents in Sacramento?
No. If rodents are still active, a licensed pest control provider removes them first. AtticareUSA then does the cleanup, sanitation, entry-point sealing, air sealing and new insulation.
How do I stop rodents from coming back after cleanup?
Seal the way in. AtticareUSA seals accessible entry points with wire mesh, polyurethane foam and cement as needed, and sanitizing the attic helps cut the scent trails that draw new rodents back. Sealing helps reduce the chance of future entry, and our rodent proofing carries a 1-year warranty.
Do I need air sealing before new insulation?
Yes, when there are gaps on the attic floor. We air seal around fixtures, piping, wiring and vents before insulation goes in, because those gaps are hard to reach once the new layer is down. ENERGY STAR guidance also puts sealing attic air leaks ahead of adding insulation (ENERGY STAR).
What happens during attic insulation removal?
We protect the work area, vacuum out the old insulation with a heavy-duty vacuum along with droppings, nests and debris, and haul it away for disposal. Then we vacuum the bare attic surfaces again, which also exposes damage and entry points the insulation was hiding.
Can I get an estimate without an in-person inspection?
Yes. We can send an estimate without an in-person inspection. You can also book a free inspection, where our estimator measures the attic and reports the findings, and the proposal arrives by email with each service priced separately.
