Attic Insulation Removal
Removing the old insulation from your attic is not always necessary but doing so can significantly improve the air quality and help people struggling with various breathing-related conditions breath easier.
Removal becomes a necessity when water damage or major rodent / pest infestations has occurred. Once the water damage or rodent / pest issues have been resolved by a professional, we work with you and your professional to coordinate the removal of the insulation.
Our insulation removal process includes:
- pre-treatment sanitization of all rodent / pest debris using DSV™ - a commercial disinfectant, cleaner, mildewstat, fungicide sanitizer - with a pump sprayer to meet recommended concentration saturation.
- removal of all blown-in and batt insulation on the attic floor (and knee walls if necessary), and
- post-treatment sanitization of any visible rodent / pest debris on all exposed areas.
Our crew begins the removal process by identifying the best location to bring in the vacuum hoses for access to your attic space. They then drape drop cloths over your flooring and furniture for protection from the hose and any loose insulation that may fall from the attic space during the removal process. The industrial vacuums remain outdoors in your garage, driveway or lawn.
Our crew will then remove all the blown-in insulation from every nook and cranny in your attic space and dispose of the old material for you leaving your space clean and free of any insulation debris.

The minimum insulation level recommended for North Texas based on the International Residential Code (IRC) insulation levels adopted by Texas is R-38 (15 inches).
However, the Energy Star recommended insulation level for North Texas is R-49 and because insulation settles over time, we provide estimates for R-44 (17 inches) and R-49 (19 inches) along with the state of Texas recommendation of R-38.
Frequently Asked Questions
When Should Attic Insulation Be Removed and Replaced?
Attic insulation should be removed and replaced when it has been damaged by rodents, contaminated by droppings or urine, affected by moisture or mold, or has deteriorated to the point that it no longer provides adequate thermal protection. Older insulation that has settled significantly or become compressed may also reduce energy efficiency and indoor comfort. A professional attic inspection can determine whether replacement is the best solution.
Can Rodents and Pests Ruin Attic Insulation?
Yes. Rodents and other pests can contaminate attic insulation with droppings, urine, nesting materials, and odors. Contaminated insulation may lose its effectiveness and can contribute to poor indoor air quality. In many cases, removing the damaged insulation and installing new insulation is the best way to restore a clean, energy-efficient attic environment.
Is It Better to Add New Insulation or Replace the Old Insulation?
If existing insulation is clean, dry, and in good condition, additional insulation can often be installed on top to improve performance. However, insulation that has been contaminated, damaged by moisture, compressed, or affected by pests should typically be removed before new insulation is installed. A professional evaluation can determine the most cost-effective approach for your home.
Will Replacing My Attic Insulation Lower Energy Bills?
Replacing damaged or inadequate attic insulation can help reduce heat transfer, improve indoor comfort, and lower heating and cooling costs. Energy savings vary depending on your home's current insulation levels, HVAC system efficiency, ductwork location, and overall construction, but properly installed attic insulation can significantly improve energy efficiency and reduce HVAC workload.
How Long Does Attic Insulation Removal and Replacement Take?
Most attic insulation removal and replacement projects are completed in two days; first day is dedicated to the insulation removal process including sanitization and air sealing and the second day involves blowing in the new attic insulation. We prefer to install on back-to-back days however, some customers want a few days in between to do other work in their attic space before the new insulation is replaced and we are more than happy to accommodate such needs.
What Type of Insulation Is Installed After Removal?
For most North Texas homes, blown-in fiberglass insulation is an excellent replacement option because it provides consistent coverage, excellent thermal performance, moisture resistance, and long-term durability. The appropriate insulation type and depth will depend on your home's construction, energy-efficiency goals, and existing attic conditions.
How Long Does a Radiant Barrier Last?
A professionally installed radiant barrier can last for decades with little to no maintenance. Their performance is not affected by moisture and they don't settle, compress, or lose effectiveness over time as opposed to blown attic insulation.
