How Much Does Attic Cleaning & Rodent Proofing Cost in Houston?
Attic cleaning and rodent proofing in Houston typically costs between $1,400 and $4,200 for a full job, with most homeowners paying around $2,600. That range covers removal of contaminated insulation, sanitizing, air-sealing entry points, and installing fresh insulation. The exact number depends on attic square footage, infestation severity, and whether you’re replacing blown-in fiberglass or upgrading to spray foam.
We give every Houston homeowner a written price before any work begins. No door-step surprises, no “while we’re up there” add-ons. You’ll know the exact dollar figure before our crew arrives.
Attic Cleaning & Rodent Proofing Cost Breakdown (2026)
Here’s what Houston homeowners actually pay for each component of the job, based on 2026 pricing in this market. Ranges reflect typical 1,500 to 2,500 square foot attics in neighborhoods like Katy, The Woodlands, Sugar Land, Pearland, and Cypress.
| Service Component | Typical Houston Price Range |
|---|---|
| Full attic inspection & assessment | $0 – $150 (free with most full-service jobs) |
| Contaminated insulation removal | $1.50 – $3.00 per sq ft of attic |
| Attic sanitizing & deodorizing | $250 – $600 |
| Rodent entry point sealing (air sealing) | $400 – $1,200 depending on number of gaps |
| Blown-in fiberglass insulation (R-38) | $1.60 – $2.80 per sq ft |
| Blown-in cellulose insulation (R-38) | $1.40 – $2.50 per sq ft |
| Spray foam insulation (open-cell, R-21) | $2.50 – $4.50 per sq ft |
| Duct repair or sealing (if rodents damaged ducts) | $300 – $1,500 |
| Whole-attic typical total | $1,400 – $4,200 |
What pushes a job toward the high end? A 3,000 square foot attic in a Memorial or Bellaire home with years of squirrel activity will cost more than a tight 1,200 square foot attic in Spring Branch with minor mouse droppings that we caught early. The insulation material you choose matters too: cellulose and fiberglass are budget-friendly, while spray foam, which is a two-part liquid that expands on contact and seals gaps airtight, runs higher on materials but often pays for itself in Houston’s July and August heat if you’re also dealing with rising air conditioning costs.
What Affects Attic Cleaning & Rodent Proofing Pricing in Houston
- Attic square footage. Insulation removal and replacement are priced per square foot. A 2,500 sq ft attic in Sugar Land just costs more to clean and reinsulate than a 1,000 sq ft attic in Pasadena because there’s more material to vacuum out and more area to cover.
- Infestation severity. Light mouse activity is straightforward. A long-running rat infestation in a Heights bungalow where droppings are packed into every corner of the loose-fill means more labor hours for removal and sanitizing, and often more entry points to seal.
- Number of entry points. Houston homes settle. Gaps around roof penetrations, soffit vents, and where the roofline meets the eaves are common entry routes. Sealing two gaps is fast. Sealing eleven is not. The more access points rodents have carved out, the higher the sealing portion of the bill.
- Insulation type you’re upgrading to. Going back with blown-in fiberglass at R-38 is the most economical path. Choosing spray foam means higher upfront cost but you also get an air seal that Houston’s humidity makes particularly valuable by reducing the moisture load in the attic.
- Duct damage. Rodents gnaw through flex duct. If rats or squirrels have shredded duct runs in a home in League City or Missouri City, repairing or replacing that duct adds to the total. We’ll point it out in the written estimate, and you’ll decide before any work starts.
- Access difficulty. Low-slope roofs, tight scuttle holes, and attics with limited crawl space in older homes around the Heights or Montrose slow the crew down. Labor hours are a real cost driver in older Houston housing stock.
How to Save on Attic Cleaning & Rodent Proofing
Saving money on this job is mostly about timing and bundling. Do the entire job in one visit: cleaning + sealing + reinsulation. Coming back separately for each phase means paying for multiple mobilizations. If you catch rodent activity early, before droppings have saturated the insulation across the whole attic, you’ll pay less for removal. And choose your insulation based on what your attic actually needs rather than what’s most expensive. Cellulose works well in many Houston attics and costs less than spray foam.
Also worth knowing: many Houston homeowners are upgrading to rodent-resistant materials where they exist. Some insulation products deter nesting better than others. Your estimator can walk through the options with the eight insulation brands we work with, including Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber. The right material is the one that fits your attic, not whatever happens to be on the truck.

FAQs – Attic Cleaning & Rodent Proofing Cost
How much does attic cleaning cost in Houston without new insulation?
Attic cleaning alone, without insulation replacement, runs $1,000 to $3,200 in Houston depending on square footage and contamination level. This covers vacuuming out old insulation, removing droppings and nesting material, sanitizing, and deodorizing. You’ll still need new insulation afterward, which is why most Houston homeowners bundle it. Call (903) 447-8369 for an exact written quote, free of charge.
Does homeowners insurance cover rodent damage in attics?
Most standard homeowners insurance policies in Texas do not cover rodent damage, including attic insulation contamination. Rodents are considered a maintenance issue rather than a sudden peril. Some policies cover resulting damage if a rodent chews through wiring and causes a covered loss like a fire, but the insulation replacement itself is typically out of pocket. We recommend checking your specific policy language with your agent.
How much does rodent proofing cost in Houston?
Rodent proofing, meaning sealing entry points throughout the attic and roofline, costs $400 to $1,200 in Houston for a typical home. Homes with extensive gap work or hard-to-reach eaves can run higher. The cost depends on how many openings the inspection turns up. We identify every gap during the free estimate, and you get a written price for sealing before we start.
Is it cheaper to clean my attic myself?
Renting a commercial vacuum and doing the work yourself can cost $200 to $500 in equipment rental and disposal fees, but the real cost shows up later: missed droppings, unsealed entry points, and insulation that’s improperly installed. Rodent droppings carry hantavirus and other pathogens. This is one job where protective equipment, proper disposal, and thorough sanitizing matter more than the upfront savings. A trained crew with commercial extraction equipment does in one day what takes a homeowner a full weekend, and we put the result in writing under our 365-Day Done Right Promise.
How long does attic cleaning and rodent proofing take in Houston?
Most full attic cleanouts with new insulation take one to two days. Rodent proofing adds a few hours on the same visit if the entry points are accessible. Large attics with heavy contamination or significant duct repair can run to three days. We give you a committed arrival window before the job starts, and our background-checked, uniformed technicians leave the job site cleaner than they found it.

Why Houston Homeowners Choose Woolsey Attic Insulation
Glenn Hartley leads our Houston team, and he’s been at this long enough to know that Houston attics have their own temperament. The humidity here means a poorly sealed attic sweats. The roof heat in August means insulation that’s under-performing shows up on your electric bill within a month. And the rodent pressure in this region, from rats in the older neighborhoods inside the Loop to squirrels in the pine-heavy suburbs like Kingwood and Conroe, is relentless.
Woolsey Attic Insulation is the attic and spray foam insulation specialist backed by the Kingswell Guarantee. Founded in 2002 as part of the Kingswell family of independently owned and operated insulation companies, we built our reputation on a simple way of working. We call it The Kingswell Way: say the price, show up in the window, leave it cleaner than you found it, put the guarantee in writing, and come back if it fails.
Every job we do in the Houston metro, from attic cleaning and rodent proofing through Attic Cleaning & Rodent Proofing in Houston, carries a written guarantee. If a repair or installation isn’t right within 365 days, we come back and fix it at no charge. No phone tag, no debate about whether it’s covered. It’s in writing.
Our team works with eight leading insulation brands so the material recommendation fits your attic, not our inventory. Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber each have strengths in different Houston housing types. A 1940s bungalow in the Heights, a 2010s production home in Fulshear, and a custom build in River Oaks don’t need the same solution. We’ll tell you which we’d use and why, and we’ll give you the number in writing before any work starts.
That’s where we are different from what Houston homeowners are used to. You get a background-checked, uniformed technician whose name you know before they arrive. You get a phone answered by a live person, any time, 24/7. You get one written price, one committed arrival window, and one guarantee that puts all of it in writing.

What Our Customers Say
"Our old insulation was flattened and basically useless. They removed it, cleaned up, and blew in new. Furnace isn't running constantly anymore and the first bill already showed it."
- Carl Yeung"Good work and a fair price on spray foam in the garage. The crew did track a bit of the old insulation through the garage, but they vacuumed it up before they left. Garage is way warmer now."
- Brenda Falk"The guy didn't try to sell me on foaming the whole house. He said the attic was where I'd actually feel it and left it at that. Honest, and he was right, our bills dropped."
- Angela Ruiz
