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

How Much Does Attic Cleaning & Rodent Proofing Cost in New Braunfels?

Attic Cleaning & Rodent Proofing in New Braunfels, TX typically runs between $1,200 and $4,800 for a standard single-story home, depending on attic square footage, the extent of rodent contamination, and whether insulation removal and replacement is needed. Most homeowners in New Braunfels pay somewhere in the $1,800 to $3,200 range once contaminated insulation is removed, the attic floor is sanitized, and entry points are sealed. If you’re adding new insulation after the clean-out – which is the right order of operations – expect the total project to land between $2,500 and $5,500 combined.

Attic Cleaning & Rodent Proofing Cost Breakdown (2026)

These are real New Braunfels market prices based on what crews are billing in the area in 2026. The ranges account for attic size, contamination severity, and whether the job is a standalone clean-out or part of a larger building-envelope project.

Service Component	Typical Price Range	Notes
Attic inspection and assessment	$0 – $150	Many contractors include this free with a written estimate
Contaminated insulation removal (per 1,000 sq ft)	$600 – $1,100	Blown-in removal runs higher; batt removal is faster and cheaper
Attic sanitization and deodorizing	$300 – $700	Fogging or direct application; heavier infestations cost more
Rodent dropping cleanup and debris removal	$200 – $500	Bagged, sealed, and hauled – not left on the curb
Rodent proofing / exclusion sealing	$400 – $1,200	Hardware cloth, foam, caulk, and flashing at entry points
Air sealing (top plates, penetrations, can lights)	$350 – $900	Should happen before new insulation is ever installed
New blown-in insulation (per 1,000 sq ft, after clean-out)	$700 – $1,400	Fiberglass or cellulose to R-38 or R-49 per climate zone
Full project (clean-out + proofing + new insulation, 1,500 sq ft attic)	$2,800 – $5,200	Most common scope for a 1,800-2,400 sq ft New Braunfels home

What Pushes the Price Up – and What Brings It Down

The biggest cost driver in New Braunfels attics is almost always insulation volume. Homes built between 1985 and 2005 in neighborhoods like Gruene, Blanco Vista, and Hunter’s Crossing often have 10 to 14 inches of aged blown-in insulation that’s been compressed by foot traffic, saturated by a roof leak at some point, and, in many cases, shredded and nested in by roof rats. Removing that volume takes time and gear – a HEPA-filtered vacuum truck is not cheap to operate.

Contamination severity is the second variable crews can’t know for certain until they’re in the attic. A modest roof rat presence – a few droppings concentrated near the eaves – is a different job than an active colony that has been operating through multiple breeding cycles. When urine has soaked into OSB sheathing, the sanitization step gets longer and the odor-treatment product cost rises. Homes near the Guadalupe River corridor or the greenbelt edges off FM 306 see this more often because of the wooded terrain that bridges the gap between open ranchland and residential rooflines.

On the other side of the ledger, a one-story home with an easily accessible pull-down stair and a clean attic layout costs less to work in than a two-story with a small hatch, HVAC equipment centered in the attic, and a low-pitch roof that puts the eaves at 18 inches of clearance. Crew hours are real costs.

One thing that doesn’t vary: under the Haven Standard, you get a written price before any work starts. Every line item, written down. No “we’ll know more once we’re up there” adjustments after the fact.

What Affects Attic Cleaning & Rodent Proofing Pricing in New Braunfels

• Attic square footage: Most New Braunfels homes built after 2000 in Veramendi, Vintage Oaks, and similar master-planned communities run 1,400 to 2,000 square feet of attic space. Every additional 500 square feet adds roughly $400 to $800 to the removal and cleanup scope, so the footprint matters more than almost anything else.
• Insulation type and depth: Older blown-in cellulose compacts over time and can weigh significantly more per square foot than modern fiberglass blown-in. When contaminated cellulose is wet or heavily soiled, bag counts go up fast. This is a common finding in New Braunfels homes built in the 1990s in subdivisions off Loop 337.
• Rodent species and infestation duration: Roof rats – common in the hill-country transition zone around New Braunfels – move faster and nest higher than Norway rats. A multi-year infestation that went unnoticed can affect a much larger percentage of the attic floor than a recent intrusion caught after one season. Duration directly affects how much insulation needs to come out and how extensive the sanitization scope gets.
• Number and complexity of entry points: A standard New Braunfels single-story with brick veneer typically has gaps at the fascia-soffit junction, around attic vents, and at utility penetrations. Sealing eight to twelve discrete points is a different job than a home with open rafter tails, a tile roof with uncapped ridgelines, and a poorly fitted HVAC chase – all of which are findings crews see regularly in older custom builds near the Guadalupe.
• Air sealing scope: Rodent proofing addresses the exterior shell. Air sealing addresses the thermal boundary – top plates, recessed can lights, and plumbing/electrical penetrations at the ceiling plane. These are separate but related scopes. New Braunfels sits in IECC Climate Zone 2, which means attic temperatures regularly exceed 140 degrees in July and August. A poorly air-sealed attic ceiling lets that heat pour into conditioned space. Doing the air sealing at the same time as the clean-out avoids reopening a clean attic floor later.
• Attic accessibility and HVAC obstacles: Homes with HVAC air handlers installed in the attic – common in New Braunfels builds from 2000 to 2015 – have ductwork, equipment platforms, and electrical connections that the crew has to work around. Tight clearances near the eaves of a low-pitch roof add time. Time adds cost. A home with a full-size pull-down stair, a standing-height ridge, and a clear attic floor is cheaper to clean than a home with a 22-by-30-inch hatch and a 5:12 pitch.

A Note on Climate Zone 2 and New Braunfels Attics Specifically

New Braunfels gets real summer heat – sustained days above 100 degrees are normal in July – and occasional hard freezes that can drop into the low 20s in January. That temperature swing is hard on attic insulation that’s already been disturbed by rodent activity. Compressed or contaminated insulation loses R-value faster in extreme conditions. When we see blown-in insulation in a New Braunfels attic that’s been nested in for two or more seasons, the effective R-value of the remaining material often tests well below what the original depth would suggest. That’s one reason we document the before-and-after condition photographically on every job – so there’s no ambiguity about what was found and what replaced it.

How to Save on Attic Cleaning & Rodent Proofing in New Braunfels

Address It Before It Spreads

The fastest way to keep cost down is to act on the first sign rather than waiting for the second or third. A fresh entry point with limited nesting activity might be a $1,500 job. The same home two breeding cycles later is likely a $3,500 job or more, because the contaminated footprint is larger and the exclusion work is more extensive. In New Braunfels, spring (March through May) is when roof rat activity picks up noticeably as temperatures climb – that’s the time to get an inspection if you’ve heard scratching over the winter.

Bundle the Clean-Out with Air Sealing and Insulation

Scheduling attic cleaning, air sealing, and insulation replacement as a single mobilization saves money compared to running them as three separate visits. The attic is already open, the crew is already staged, and the inspection work that informs each scope is done once. When we price a combined job as a full Attic Cleaning & Rodent Proofing project in New Braunfels, the per-square-foot cost for the insulation phase is typically lower than if the insulation work were booked separately afterward.

Get a Written Price Before You Agree to Anything

This should be non-negotiable. Under Haven Standard Clause 1, a written price and written scope come before any work starts – no exceptions. If a contractor gives you a verbal range and says they’ll know more once they’re in the attic, that’s a structure that almost always ends with a higher number after the work is underway. Get the number in writing before anyone sets up a ladder.

Use a Free Second Opinion Before You Commit

If you’ve already received a written estimate from another contractor, bring it to us. We’ll read it with you, line by line, and tell you whether the scope matches what’s actually in your attic, whether the materials are appropriate, and whether the price makes sense for the New Braunfels market in 2026. That review is free, and it’s not a sales pitch – it’s a read of what you were handed.

Don’t Pay for Insulation Before the Air Sealing Is Done

This is where homeowners frequently lose money. New insulation installed over an unsealed attic floor still allows conditioned air to escape through top-plate gaps, recessed light housings, and plumbing chase openings. The insulation adds R-value, but the air leakage penalty significantly undercuts the energy savings. Wes Okafor and the Envelope Insulation Co. team will not install insulation over an unsealed attic floor – ever. That’s not an upsell; it’s the correct order of operations, and it’s what separates a job that performs from one that looks done but doesn’t.

FAQs – Attic Cleaning & Rodent Proofing Cost in New Braunfels

How much does attic cleaning and rodent proofing cost in New Braunfels, TX?

For a typical New Braunfels home with 1,200 to 1,800 square feet of attic, expect a total project cost of $1,800 to $3,600 for contaminated insulation removal, sanitization, and exclusion sealing. If the attic is larger, the infestation is multi-season, or the home has complex entry-point geometry, the number can reach $4,500 to $5,500. Adding new insulation after the clean-out brings most projects to a combined total of $2,800 to $5,500. Call (830) 243-6352 for a written price specific to your attic – estimates are free and the price is flat before work starts.

Is it cheaper to just re-insulate over old contaminated insulation?

No, and doing so can create a more expensive problem later. Installing new insulation over rodent-contaminated material traps allergens, odor compounds, and biological waste against the ceiling plane permanently. It also buries active nesting material that rodents may return to. The correct scope – and the only scope Envelope Insulation Co. will quote – is to remove contaminated insulation, sanitize the attic floor, seal air leaks and entry points, and then install new insulation. Skipping the removal step typically costs more to correct than the removal itself would have cost at the time of the original project.

How long does attic cleaning and rodent proofing take in New Braunfels?

Most standard residential attic clean-outs in New Braunfels take one to two days. A smaller attic with limited contamination and straightforward entry points can be completed in a single day. Larger attics – 2,000 square feet or more, common in newer Veramendi and Vintage Oaks builds – or those with severe contamination or complex exclusion work typically run two days. If new insulation is being installed as part of the same project, add a half day to a full day depending on the method and depth.

Will my homeowners insurance cover attic rodent damage in New Braunfels?

Most standard homeowners insurance policies in Texas exclude rodent damage, classifying it as a maintenance or pest-control issue rather than a sudden covered loss. There are exceptions – some policies cover the resulting damage if a rodent chewed through wiring that caused a fire, for example – but the attic cleaning and insulation replacement itself is almost always an out-of-pocket cost. Check your declarations page under exclusions, and call your insurer before assuming coverage applies. We can provide a detailed written scope and itemized pricing that some homeowners use to support a claim review, though we can’t guarantee any coverage outcome.

How do I know if rodent proofing actually worked?

The honest answer is: documentation and follow-up. On every job, Wes Okafor’s crew provides a Documented Photo Record of every entry point found and sealed, with before-and-after photos of the attic floor condition. That record is yours – not available on request, included automatically. For the air-sealing component, applicable jobs include a before-and-after blower-door test – a pressurization reading that shows, in a single number, how much conditioned air the building envelope was losing before and after the work. You’re not taking our word for it; you have the numbers. The 365-Day Done Right Promise applies to the full scope: if a sealed entry point fails within a year, we make it right in writing.

What rodent entry points are most common in New Braunfels homes?

In New Braunfels specifically, the most frequent findings are gaps at the fascia-to-soffit junction (common in homes with older vinyl soffit panels), uncapped or damaged gable vents, gaps around HVAC conduit and refrigerant line penetrations through exterior walls, and open cavities where roof lines meet at a valley or transition. Homes in the hill-country terrain near Canyon Lake Road and the FM 306 corridor also frequently show gaps at the roofline where tile or metal roofing meets the fascia board – a transition that wood-framed homes in this area handle differently than homes in flatter suburban markets. A proper exclusion job addresses all identified openings, not just the ones that are easiest to reach.

What the Full Attic Cleaning Project Looks Like, Step by Step

Some homeowners want to understand the sequence before they commit. Here’s what the job actually looks like from first contact to close-out.

Step 1: Written Estimate Before Anything Else

We schedule an attic inspection, document what’s there with photos, and produce a written price and written scope. That document includes every line item – removal, sanitization, exclusion, air sealing, and insulation if applicable. Haven Standard Clause 1: no work starts without it.

Step 2: Contaminated Insulation Removal

A HEPA-filtered vacuum system pulls existing insulation from the attic floor and deposits it into sealed disposal bags. The crew wears full PPE – respirators, Tyvek suits, gloves – because rodent waste in attic insulation carries real respiratory risk. This is not a job to approach without proper equipment, and it’s not something we’d describe as a weekend DIY project. The biology of what accumulates in an active rodent attic – hantavirus, leptospirosis, and secondary allergens from droppings and dander – makes professional-grade removal and sanitization the responsible path.

Step 3: Sanitization and Odor Treatment

Once the insulation is out, the attic floor is fogged or direct-applied with an enzyme-based sanitizer that breaks down organic waste compounds at the molecular level. In severe cases, a second application is done after the first has dried. The goal is a clean substrate before anything else goes in.

Step 4: Air Sealing

With the attic floor bare, every top-plate gap, recessed light housing, plumbing penetration, and electrical chase is sealed with two-part spray foam, fire-rated caulk, or rigid blocking as appropriate to the location. This step happens before new insulation – always. Installing insulation over an unsealed floor is the single most common way a well-intentioned attic project underperforms, and it’s something Envelope Insulation Co. won’t do.

Step 5: Rodent Exclusion

Every entry point identified during the inspection is sealed from the exterior using hardware cloth, galvanized flashing, foam backer with caulk, or rigid blocking depending on the gap type and location. Soffit vents are inspected and replaced or screened if compromised. Gable vents are assessed for screen integrity. The written scope names each point addressed, and the photo record shows the before and after.

Step 6: New Insulation Installation

If the scope includes insulation replacement – which it usually does, because contaminated insulation that’s been removed can’t go back – blown-in fiberglass or cellulose is installed to the depth required for the project’s target R-value. In New Braunfels, IECC Climate Zone 2 recommendations call for R-38 at minimum and R-49 for new construction. Materials come from manufacturers including Owens Corning, Johns Manville, Knauf, and GreenFiber – no proprietary product lock-in, and no markup games on material brand selection.

Step 7: Documented Photo Record and Close-Out

When the crew leaves, you receive a Documented Photo Record covering the full scope: pre-work attic condition, each entry point sealed, the sanitized floor, and the finished insulation surface. On applicable jobs, before-and-after blower-door numbers are included so you can see the air-sealing result in a single measurement rather than taking our word for it. The 365-Day Done Right Promise is in writing before we leave.

Why the Order of Operations Matters for New Braunfels Homeowners

New Braunfels sits in a part of Texas where the building envelope gets tested hard from both ends – brutal summer heat above 100 degrees and freezes that can split pipes in January. An attic that’s been cleaned and re-insulated without air sealing will still bleed conditioned air through every gap in the ceiling plane, and those gaps don’t disappear just because new insulation is on top of them. The energy penalty is real, measurable, and avoidable.

Since 2016, the Envelope Insulation Co. team has completed work on more than 9,000 homes – every one with a written price before work started and a documented record when the crew left. Wes Okafor built the company around the observation that the two most common complaints about insulation contractors aren’t about materials or technique – they’re about pricing surprises and work that can’t be verified after the fact. The Haven Standard addresses both directly: flat written price before any work starts, documented photo record when the crew leaves, and blower-door numbers on applicable jobs so the result is measured, not just claimed.

That structure doesn’t cost extra. It’s the baseline for every job in New Braunfels and everywhere else we work.

Key Takeaways

• Attic cleaning and rodent proofing in New Braunfels typically costs $1,800 to $3,600 for a standard 1,200-1,800 sq ft attic; combined with new insulation, most projects run $2,800 to $5,500.
• The biggest cost drivers are attic square footage, infestation duration, and the number of entry points requiring exclusion work.
• Air sealing happens before insulation – always. Installing new insulation over an unsealed floor is the most common reason attic projects underperform.
• New Braunfels homes near wooded corridors (Guadalupe River, FM 306 greenbelt edges) see roof rat activity more frequently due to terrain that connects ranchland to residential rooflines.
• Every Envelope Insulation Co. job in New Braunfels comes with a written price before work starts, a Documented Photo Record at close-out, and the 365-Day Done Right Promise in writing.
