Professional Crawl Space Cleaning & Insulation
Up to 40 percent of the air on your first floor can come directly from the crawl space beneath your home. When that space is damp, dirty, poorly insulated, or harboring pests, that air quality problem doesn’t stay contained underneath the house.
Left unaddressed, a neglected crawl space becomes a source of musty odors, wood rot, and rising humidity that no amount of air conditioning can fully offset. It also tends to attract the same rodent activity that causes problems in attics.
We provide full crawl space services, cleaning, insulation, moisture control, and pest exclusion, so the air moving into your home starts out clean instead of contaminated.
Our Specialized Crawl Space Services
A healthy crawl space depends on addressing several things together, not one at a time. Explore our comprehensive cleaning, insulation, and proofing solutions designed to protect your home from the ground up.
Crawl Space Cleaning Services
We remove construction debris, rotting wood, and hazardous junk. Our team clears the area down to the foundation, creating a sanitary baseline for repairs and encapsulation.
Crawl Space Insulation Services
We install or upgrade floor insulation to separate your living space from unconditioned air below, which helps reduce heat loss and lower energy bills.
Crawl Space Decontamination & Rodent Exclusion
We use hospital-grade disinfectants to eliminate mold spores, bacteria, and odors, ensuring the air entering your home is safe and improving indoor air quality. We also identify and seal entry points that let rats, mice, and other pests into the crawl space.
Moisture Control and Encapsulation
We install heavy-duty vapor barriers to block ground dampness, and for crawl spaces with a history of moisture issues, full encapsulation seals out dampness, outside air, and the dust and allergens that come with it.
Why Encapsulation Matters for Long-Term Protection
Cleaning solves the immediate problem, but encapsulation is what keeps it from coming back. Fully sealing the crawl space with a heavy-duty liner blocks moisture, pests, and outside air from re-entering, creating a controlled, dry environment instead of one that needs repeated attention. For crawl spaces with a history of moisture or pest issues, encapsulation is usually the difference between a lasting fix and a recurring one.
Signs Your Crawl Space Needs Attention
A few warning signs tend to show up before a crawl space problem becomes obvious elsewhere in the home:
- Musty odors indoors: A persistent musty smell, especially on the first floor, often traces back to moisture or mold below.
- Visible mold or moisture: Damp insulation, standing water, or mold on joists are clear signs the space needs attention.
- Higher indoor humidity: If your home feels humid even with the air conditioner running, your crawl space may be the source.
- Pest droppings or damage: Rodent activity in the crawl space often mirrors what shows up in the attic.
If you notice any of these signs, it’s worth having the space inspected before the problem spreads further into your home.
Why Homeowners Choose Us for Crawl Space Services
Crawl space work is easy to do halfway and hard to verify once it’s closed back up, so we focus on getting it right the first time. We treat cleaning, insulation, moisture, and pests as connected problems rather than separate services, and the same team that handles attic insulation and rodent proofing brings that same understanding of how crawl space conditions affect the rest of your home.
We rely on heavy-duty vapor barriers, insulation, and sealing materials built to hold up against ground moisture over time, and every job is backed by a one-year workmanship warranty, so if anything about the work needs a second look, we come back and take care of it.

House is more comfortable and utility bills are noticeably lower. Solid work all around.
After comparing several companies, went with Attic Construction for our energy efficiency upgrade. They sealed ducts, added insulation, and installed a moisture barrier. Transparent pricing, showed up when they said they would, and the results speak for themselves.

Very pleased with the insulation work Attic Construction did in Irving.

Thank you Attic Construction for a perfect job with a very fair price !
We saw this company doing A project to our neighbor and we asked them to come to do inspection at our attic because we had rodent problem too. We decided to do the same project as our neighbor did and we have to say that we had the best experience I ever had with any contractor I ever worked with…

Frequently Asked Questions About Crawl Space Cleaning
Why do I need a vapor barrier?
A vapor barrier stops ground moisture from evaporating into your crawl space, which helps prevent mold growth and wood rot over time.
What is crawl space encapsulation?
Encapsulation means completely sealing the crawl space with a heavy-duty liner to block moisture, pests, and outside air, creating a controlled, dry environment.
How do I know if I need crawl space cleaning?
Musty odors on your first floor, visible mold or moisture, higher indoor humidity, or signs of pest activity are all indications that your crawl space needs attention.
Does crawl space floor insulation save money?
Yes. It separates your living space from unconditioned air below, which reduces heat loss and can lower your energy bills.
Can a dirty crawl space make me sick?
Yes. Through what’s known as the stack effect, air from the crawl space rises into your living areas, carrying dust, mold spores, and other contaminants with it.
