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

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

Attic cleaning and rodent proofing in Dallas typically runs $1,200 to $4,500 for a standard single-family home, with most homeowners landing between $1,800 and $3,200. The price covers removal of contaminated insulation, sanitizing and deodorizing the attic space, sealing entry points rodents use, and installing fresh insulation if the old material was ruined. Smaller attics under 1,000 square feet with light contamination start around $900, while larger homes with extensive rodent damage and full insulation replacement can reach $6,000 or more.

Attic Cleaning & Rodent Proofing Cost Breakdown (2026)

Here’s what Dallas homeowners can expect to pay for each component of the job. These ranges reflect pricing we see across Dallas, Plano, Garland, Mesquite, and the surrounding metro as of 2026.

The single biggest cost variable is square footage. A 1,000-square-foot attic in an East Dallas bungalow costs less than a 3,500-square-foot attic in a North Dallas or Plano two-story. Insulation depth matters too: attics with 12 to 18 inches of blown-in material take longer to remove than attics with 6 inches. Rodent damage level is the third major factor. If rats have been nesting for two years, expect more sanitizing, more deodorizing, and more entry-point sealing than a home with a single squirrel that got in last month.

What Affects Attic Cleaning & Rodent Proofing Pricing in Dallas

No two attics are the same, even in the same neighborhood. Here’s what actually moves the number.

• Attic square footage and ceiling height. More space means more insulation to remove and more area to sanitize and seal. Low-pitch roofs with tight clearance slow the crew down, which raises labor time. Ranch-style homes in Richardson and Mesquite with shallow attics often take longer per square foot than taller attics in newer Frisco builds.
• Type and depth of existing insulation. Blown-in fiberglass vacuums out faster than dense-packed cellulose that’s been compressed for 20 years. Homes built before 1990 in Dallas sometimes have layers of old batt insulation covered by blown-in material, which doubles removal time.
• Severity of rodent contamination. Light activity means a few droppings and one entry point. Heavy infestation means soaked insulation, chewing damage on ductwork, and odor that’s penetrated wood sheathing. In neighborhoods like Lakewood and Casa Linda with mature trees, we regularly see squirrel damage that’s gone unnoticed for years because the attic access is in a closet ceiling.
• Number and location of entry points. Rats and mice enter through roofline gaps, vent openings, plumbing penetrations, and even gaps around AC lines. A single-story home with 12 roof penetrations needs more sealing than a two-story with 8. Rodent proofing labor in Dallas runs higher on homes with gable vents, which are common in older Garland and Irving construction.
• Ductwork condition. If rodents have chewed through flex duct, you’re looking at repairs that range from $200 for a small patch to $1,500+ for significant section replacement. We flag this during inspection, not after the job starts, so the written price covers what we actually find.
• Access and attic layout. Attics with plywood decking or HVAC equipment crowding the workspace take longer to navigate. Some Dallas homes built in the 1960s and 1970s have attic access hatches too small for standard equipment, requiring more handwork.

How to Save on Attic Cleaning & Rodent Proofing

There’s a difference between paying less and paying twice. Here’s how to keep the number reasonable without cutting corners that cost more later.

• Get a written, itemized price before work starts. At Alden Insulation Dallas, the price is in your hand before a single tool comes off the truck. That means no door-knock revisions, no “discovered extra damage” surcharges. If the written number says $2,400, the invoice says $2,400, even if the job runs long.
• Combine cleaning with insulation replacement. If your insulation is already contaminated, you’re removing it anyway. Installing fresh blown-in insulation at the same time costs less in labor than scheduling two separate visits. You also get the benefit of bringing your attic up to current R-value standards for the Dallas climate, which the Department of Energy recommends at R-38 to R-60 for our region.
• Address rodent activity early. A single entry point sealed in month one costs a few hundred dollars. Twelve months of nesting, breeding, and chewing turns that into a full removal and sanitizing job. We see this pattern constantly in older Dallas neighborhoods like Oak Cliff and Preston Hollow, where established trees and older roof lines give squirrels and rats easy access.
• Ask about the guarantee before you sign. The Alden 365-Day Done Right Promise covers every rodent proofing and attic cleaning job in writing. If the work fails within a full year, we return at no charge. That single guarantee protects you from paying twice for the same repair, which is the most expensive outcome we see in this trade.
• Verify what materials are being installed. We install insulation products from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber. You can research any of those brands before committing. If a contractor can’t name what they’re putting in your attic, that’s a red flag.

Call (940) 748-1726 and we’ll walk through your attic’s specific situation. The estimate is free, and you’ll get a written price that covers the entire job, no hidden line items.

FAQs – Attic Cleaning & Rodent Proofing Cost

How much does attic insulation removal cost in Dallas?

Attic insulation removal in Dallas runs $1.50 to $3.00 per square foot, which for a typical 1,500-square-foot attic means $2,250 to $4,500 for full removal. The price depends on insulation type, depth, and how badly it’s contaminated. Call (940) 748-1726 for an exact quote based on your attic’s square footage, estimates are free.

Is attic cleaning and rodent proofing worth the cost?

For most Dallas homeowners, the $1,800 to $3,200 cost is recoverable in energy savings and avoided damage. Rodent-contaminated insulation loses R-value, and rats in the attic routinely chew through ductwork and wiring, which runs far more than the cleaning itself. The 365-Day Done Right Promise on every Alden job means if the proofing fails within a year, we return at no charge. That guarantee changes the math on whether the job is worth doing.

How long does attic cleaning and rodent proofing take?

Most Dallas attic cleaning and rodent proofing jobs are completed in one to two days. A 1,200-square-foot attic with moderate contamination and three or four entry points is typically a one-day job. Larger attics with heavy rodent damage, ductwork repair, and full insulation replacement can stretch to two or three days. We arrive inside the scheduled window, not a vague half-day range, and the crew is background-checked and uniformed.

Can I clean my own attic instead of hiring a contractor?

You can, but most Dallas homeowners underestimate what’s involved. Rodent droppings carry hantavirus risk, requiring respirators and proper protective equipment. Insulation removal requires a commercial vacuum system, not a shop vac. And rodent proofing only works if you find and seal every entry point, which takes trained eyes. If the job is done wrong and rodents return, you’re paying again. The written guarantee Alden provides means you pay once.

How much does blown-in insulation cost after a rodent-proofing job in Dallas?

Blown-in insulation installation in Dallas runs $1.50 to $3.50 per square foot depending on the material and target R-value. For a 1,500-square-foot attic brought to R-38, that typically lands between $2,250 and $5,250. We install products from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber, and you’ll know the exact brand and R-value on your written quote before we start.
