Attic Cleaning & Rodent Proofing Cost - Same-Day Service, Done Right the First Time

How Much Does Attic Cleaning & Rodent Proofing Cost in Austin?

Attic cleaning and rodent proofing in Austin, TX typically costs between $1,500 and $4,500 for a full job on a standard 1,500 to 2,500-square-foot home. Smaller jobs, like a basic attic cleaning with minor entry-point sealing, start around $700, while extensive rodent remediation with insulation removal, sanitizing, and full exclusion work on a large or heavily infested attic can reach $7,000 or more. Most Austin homeowners pay right around $2,800 for the complete package: remove contaminated insulation, clean and sanitize, seal entry points, and install fresh insulation.

Attic Cleaning & Rodent Proofing Cost Breakdown (2026)

The total price depends on what your attic actually needs. Some homes just need cleaning and a few entry points sealed. Others have rodent damage so extensive that the insulation has to come out entirely and the attic has to be treated like a biohazard zone. Here’s what each component costs in the Austin market as of 2026:

These ranges reflect what we see across the Austin metro in 2026, from Round Rock to Buda, from Steiner Ranch to the east side neighborhoods of Mueller, Holly, and Cherrywood. The biggest variable is almost always the condition of your insulation and how long rodents have been active up there. In Austin’s climate, attics get brutally hot in summer, and that heat bakes rodent waste into insulation fibers. By the time homeowners call us, the insulation often can’t be salvaged.

What to Expect When You Call

At Woolsey Insulation Austin, every job starts the same way: we inspect, we measure, and we hand you a written price before any work begins. We don’t give ballpark-only estimates that balloon on day one. The Kingswell Guarantee means a written price, a set arrival window, a clean job site, and a written guarantee on the work, 365 days, no exceptions. Glenn Hartley, who leads our Austin team, has been doing attic work in this market long enough to know that honesty about cost is the rarest thing in this trade. We lead with it.

What Affects Attic Cleaning & Rodent Proofing Pricing in Austin

No two attics in Austin are the same. Here are the factors that move your price up or down, and why:

• Attic size and accessibility. A 900-square-foot attic in Allandale costs less to clean and reinsulate than a 2,800-square-foot attic in Westlake. Low-slope roofs, tight access hatches, and ductwork crowding the workspace all add labor hours.
• How long rodents have been active. If you caught the problem in the first month, we’re likely cleaning and sealing. If squirrels or roof rats have been up there for a year, the insulation is saturated with urine and droppings, and it has to go. That’s a $1,500 difference overnight.
• Type of insulation currently installed. Blown-in fiberglass and cellulose are relatively fast to remove. Old rock wool batts from a 1970s house pull out in sections. Spray foam insulation that has rodent tunnels through it has to be cut and scraped out, and that’s the slowest, most expensive removal we do.
• Number and type of entry points. Older Austin homes, especially the pier-and-beam houses in Hyde Park, Bouldin Creek, and Travis Heights, often have multiple gaps where gables meet eaves, plus uncapped vents and open soffit returns. Every entry point needs to be found and sealed. Rodents that found one way in will find the next if we miss it.
• Rodent species. Roof rats and house mice are the two most common attic invaders in Austin. Roof rats are larger, more destructive, and leave bigger messes. Squirrels, which are active during the day and nest in groups, create the heaviest contamination in our experience. Squirrel jobs in Barton Hills and Tarrytown regularly run at the high end of our cleaning range.
• Sanitizing method. A basic HEPA vacuum and spot treatment costs less than full antimicrobial fogging after heavily soiled insulation removal. In most cases we recommend the full treatment because Austin’s heat and humidity turn even small amounts of rodent urine into a persistent odor problem. You’ll smell it in the living space on a hot afternoon if it isn’t properly treated.
• Insulation replacement choice. After cleaning, you need new insulation. Blown-in fiberglass is the most common and most affordable. Cellulose costs slightly more but fills cavities better. Spray foam insulation, which is excellent for sealing and insulating in one pass, runs higher but delivers the strongest air seal, especially important in Austin where attic temperatures regularly hit 140 degrees in August.

One Austin-specific factor worth understanding: our freeze-and-thaw cycle. February’s freezes drive rodents indoors more aggressively than anything else. Homeowners who had rodent issues in early 2024 and 2025 learned fast how quickly roof rats find their way through a gap the size of a quarter. That’s why sealing work is rarely minimal in central Texas attics, there are simply a lot of small cracks in homes built in the 1960s through 1980s when venting standards were looser.

Does Homeowners Insurance Cover Attic Rodent Damage?

The short answer is usually no. Most homeowners policies in Texas exclude damage caused by rodents, birds, insects, and other vermin. A standard HO-3 policy treats rodent damage as a maintenance issue, not a covered peril. That means the cost of cleaning, proofing, and reinsulating your attic after a rodent infestation falls on you. There are exceptions: if a rodent chews through electrical wiring and causes a fire, the fire damage may be covered under your base policy, but the damaged wiring and the rodent problem itself typically are not.

What we tell homeowners in Austin is simple: don’t wait for the damage to get expensive enough to worry about insurance. A rodent problem in your attic costs $2,000 to $4,000 to fix properly. A deferred rodent problem that spreads into your walls, destroys your HVAC ductwork, and ruins your ceiling from urine soak-through can run past $10,000. Paying for prevention early, or remediation as soon as it’s discovered, is always the cheaper path. Get a free inspection and a written quote before you assume the worst about the price.

How the Kingswell Way Works on Attic Cleaning Jobs

The Kingswell Guarantee is woven into every job we do, and here is exactly what that looks like in practice. First, we inspect the attic ourselves. We crawl it, we measure it, we photograph it, and we know exactly what’s up there before we quote a single dollar. Then we hand you a written price, not a verbal estimate. That number does not change at the door. Every Woolsey job runs with a committed arrival window, background-checked, uniformed technicians, and a promise to leave the job site cleaner than we found it. After the work is complete, you get a written guarantee covering the work for 365 days. If something isn’t right, we come back and we make it right at no charge.

That’s the entire promise. No fine print. No door-step surprises. Glenn Hartley built this Austin operation on that premise: say the price, show up when you said you would, do the work right, and back it in writing.

Attic Cleaning & Rodent Proofing Cost FAQs

How much does rodent proofing cost alone without cleaning in Austin?

Rodent proofing and exclusion work alone typically runs $300 to $800 for sealing common entry points around an average Austin home. If your attic is clean and dry, and rodents are just finding their way in through a couple of vents or eave gaps, we can seal those points, install exclusion mesh where needed, and be done in half a day. The catch: we need to confirm the attic is actually clean. Rodents rarely come in without leaving waste behind. A quick inspection will tell you if you need cleaning too. Call (361) 418-9997 for a free inspection and written quote.

Is attic cleaning and rodent proofing cheaper in the winter in Austin?

Pricing is relatively flat year-round in Austin, but winter is when demand spikes because rodents push indoors during cold snaps. Spring and early summer often offer more scheduling flexibility. We never inflate prices in high-demand periods, and we don’t run fake discounts in low ones. The written price you get is based on the actual condition of your attic and the work required, not the season. If you think rodents are already in your attic, the smartest time to handle it is the day you discover it, since every week of infestation adds damage and cost. Call (361) 418-9997 and a live person answers, 24/7.

Do I need to replace the insulation after rodent cleaning?

Most of the time, yes. In our experience across Austin, roughly 8 out of 10 attics with any significant rodent history need full insulation removal and replacement. Rodent urine soaks into blown-in insulation fibers, and feces break down into dust that’s impossible to vacuum out completely. The smell lingers, especially in Texas heat. On a standard 2,000-square-foot Austin home, adding insulation replacement to a cleaning job typically adds $1,500 to $3,000. If the attic is lightly trafficked, we may be able to clean and treat the existing insulation, but that’s an inspection call. Call (361) 418-9997 and we’ll walk the attic with you, photos in hand.

How long does attic cleaning and rodent proofing take?

A standard attic cleaning, exclusion, and reinsulation job in Austin takes one to two full days, start to finish. Small jobs where the insulation can stay and we’re cleaning plus sealing entry points run half a day. Large jobs with heavy contamination, spray foam removal, or extensive entry-point sealing can take three days. You’ll know the exact timeline when you get your written quote, because our arrival window and job duration are part of the Kingswell Guarantee. No mystery windows. Call (361) 418-9997 for a free estimate.

Can you come out today?

In most cases, yes. A live person answers the phone 24/7 at (361) 418-9997, and we can usually get a technician out to your Austin home the same day for an inspection. If we find an active rodent problem, we often start exclusion work immediately so the animals stop getting in, then schedule the cleaning and reinsulation as a follow-up. Same-day service across Austin, Round Rock, Cedar Park, Pflugerville, and the surrounding metro is something we prioritize. Call (361) 418-9997 and we’ll be straight with you about what we can schedule.

Our Attic Cleaning & Rodent Proofing Process in Austin

We walk each Austin attic through a four-step process, and we explain it before we start so you know exactly what you’re paying for and why.

Step 1: Full Attic Assessment

We inspect every corner of the attic: the insulation depth and condition, the wiring runs, the duct connections, the roof deck, the vents, the eave lines, and every gap where a rat or squirrel could squeeze through. In Austin homes, we frequently inspect older gable vents with rotted framing, soffit returns that were never screened, and pipe penetrations around plumbing stacks that leave finger-sized gaps into the attic. We take photos and we show you what we found.

Step 2: Removal and Cleaning

If the insulation is contaminated, we remove and bag it. Every bag is sealed and carried out through the house with the floors protected. Then we HEPA vacuum the entire attic space, treating the framing and decking with an antimicrobial treatment designed to break down rodent urine and dropping residue. This is the part of the job where a shortcut ruins everything, so we don’t take them.

Step 3: Exclusion and Proofing

We seal every entry point we find and the ones that commonly fail in Austin homes, even if rodents haven’t used them yet. Galvanized steel mesh across gable vents, hardware cloth over soffit returns, sealant around pipe penetrations, and chimney caps where needed. The goal is an attic that a rat or squirrel cannot physically enter. Not harder to enter. Not less likely. Closed.

Step 4: Reinsulation

Once the attic is clean and sealed, we install new insulation matched to your home and your budget. We work with eight leading insulation brands, including Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber, so the recommendation fits the attic, not whatever happens to be on the truck. For most Austin attics, blown-in fiberglass or cellulose is the right answer. For homes where air sealing is a priority, spray foam insulation often makes sense. We’ll show you the numbers for each option and let you decide.

The second step, removing and replacing contaminated insulation, is the stage where safety matters most. Rodent waste carries hantavirus risk, and removing soiled insulation without proper respiratory protection and containment is dangerous. This is one job where the do-it-yourself savings are never worth the exposure. A trained crew with proper PPE, HEPA filtration, and sealed removal bags is genuinely safer for your household. We treat it with the same seriousness we would apply in our own homes.

Why Austin Homeowners Choose Woolsey for Attic Cleaning & Rodent Proofing

Most homeowners in Austin have been burned by a contractor at least once. A quote that changed when the crew showed up. A promised window that came and went.
