Why It Matters
What's in Your Crawl Space
Ends Up in Your Air
In a home with a crawl space, a large share of the air you breathe on the ground floor actually rises up from below through the stack effect. So when the crawl space is damp and full of debris, rodent droppings, or mold, those contaminants and allergens don't stay down there — they end up in your living space, along with musty odors and higher humidity.
Crawl space cleaning fixes the source. We clear out the debris and rodent waste, remove contaminated insulation and vapor barrier, address the moisture that caused it, and sanitize the space. When rodents are involved it pairs naturally with rodent control, and with fresh crawl space insulation once it's clean and dry.
- Healthier air throughout your home
- Dampness and standing water eliminated
- Rodent waste and debris removed
- Fewer airborne contaminants and allergens
- Mold and moisture issues addressed

What's Involved
What Crawl Space
Cleaning Involves
A proper crawl space cleaning is about moisture and contamination, not just clearing junk. Here's what it covers.
Debris & waste removal
We clear out debris, rodent droppings, nesting, and general buildup safely, with proper protective equipment.
Contaminated insulation removal
Insulation and vapor barrier fouled by rodents or moisture can't be cleaned — we remove and haul it away.
Moisture control
We address the dampness, standing water, or leakage behind the problem, since moisture is what keeps mold and pests coming back.
Sanitize & disinfect
We sanitize and disinfect the space to neutralize the bacteria, allergens, and odors that rise into your home.
Seal & rodent-proof
We can seal entry points and add a fresh vapor barrier so your clean, dry crawl space stays that way.
Do You Need It?
Signs Your Crawl Space
Needs Cleaning
Crawl space trouble almost always shows up upstairs first. If any of these sound familiar, it's worth a look below.
Musty odors in the house
A persistent musty or damp smell drifting up into your rooms is one of the most common signs of a dirty crawl space.
Dampness or standing water
Moisture, puddles, or condensation under the house feed mold and rot and make the space inviting to pests.
Mold or mildew
Visible mold on framing, insulation, or the vapor barrier means moisture has taken hold and needs to be cleared.
Rodent droppings or nesting
Droppings, nests, or shredded insulation under the house are a health hazard that won't clear on its own.
Sagging or damaged insulation
Insulation falling from the subfloor is often waterlogged or rodent-damaged — a sign the space needs attention.
Humidity or allergy symptoms
A clammy home or worsening allergies can trace back to damp, contaminated air rising from the crawl space.

Rodent intrusion and the associated damage they cause is the worst! After reading reviews, I decided on Attic Pros because they have great reviews and because they specialize in the work I needed. I was not disappointed. Within a few days of reaching out, Tom came out and did the estimate. The work began only two business days later! The work was scheduled over two days but they did it all in one! The guys arrived on time and were cheerful, polite, and pleasant to deal with. Kevin showed me pictures and video periodically throughout the day so I could see the work, start to finish. He answered all of my questions and explained everything clearly and patiently. Before they left they made sure there was no trash or debris left behind. The crawl space now looks like it belongs under a brand new home, it’s that clean and tidy. I highly recommend Attic Pros for all of your insulation and rodent elimination needs. Update: I came back and edited this, removing a star. The work and workers were great. However, a few days after the job, Julian from their business office messaged me that they had not received payment and the invoice was past due, even though they were paid IN FULL THE DAY OF WORK. Proof of payment was provided and he messaged me that a receipt would be sent when the payment was deposited. Very disappointing and unprofessional of him to go after a customer for payment when the problem lies with their accounts receivable. 10/14/26 I am adding to my review because issues had been discovered over time. They had missed a place where rats were entering, even though they had been out twice to check traps and found some. This guy did a less than thorough cleaning but he did close off the previously missed access point. My rat intrusion problem has been ongoing. 11/6/26 Attic Pros followed through and sent out Raul, an excellent worker, who took care of everything and made it right. While it may have been problematic for a bit, they kept working until it was all made right. They have been kind and communicative, specifically Paula. I will be calling them again in the Spring to work on a different area of my home.

UPDATE: I really appreciate the company followed up after my concerns were raised. They took accountability for what happened, handled the situation professionally, and offered to fix all the issues. Their responsiveness and willingness to make things right completely changed my impression, and I’m happy to update my review to 4 stars. They ultimately completed the job, but the overall experience was far from hassle-free. During the process, they damaged our ceiling and later repaired it, though the result was not fully satisfactory. There were multiple mistakes along the way, both in the actual work and in billing, which meant we had to stay very involved to ensure nothing was missed. Communication was also a challenge. Our consultant, Tom, was not as responsive as expected, especially given how busy schedules can be in the Bay Area. We often had to follow up multiple times to get updates or have issues addressed. Overall, while the job was eventually finished, the process required more oversight and effort than it should have. If I were to go through this again, I would choose a different company.

If that space is damp, moldy, or full of rodent waste, those contaminants and odors rise into your living areas — which is why cleaning the crawl space improves the air you actually breathe.
It can be. Standing moisture feeds mold and mildew, and rodent droppings and urine carry bacteria and allergens. Because that air circulates up into your home, a neglected crawl space can worsen allergies and indoor air quality — not just sit harmlessly out of sight.
It's tough and risky work. Crawl spaces are cramped, and disturbing rodent droppings, mold, or wet insulation without proper protective equipment can release harmful particles. Professional cleaning handles the removal, moisture, and sanitizing safely — and gets to the source so it doesn't come right back.
Yes. Insulation and vapor barrier fouled by rodents or soaked by moisture can't be cleaned — they hold contaminants and lose their effectiveness. We remove and haul them away, and can install a fresh vapor barrier and insulation once the space is clean and dry.
Both. Moisture is what keeps mold and pests coming back, so we address the dampness, standing water, or leakage as part of the job — and can seal the space and add a vapor barrier to keep it dry going forward.
Yes. Crawl spaces are a favorite spot for rodents, so cleaning often goes hand in hand with rodent control and rodent-proofing. We can remove the pests, seal their entry points, and clean and sanitize the space as one coordinated job.
It depends on your home, but it's worth an inspection any time you notice musty odors, moisture, or signs of pests — and after any rodent problem or water intrusion. Catching issues early keeps a small cleanup from turning into mold or structural damage.
Most residential crawl space cleanings are completed in a single visit. Timing depends on the size of the space, how much debris and contamination there is, and whether moisture work or a new vapor barrier is involved. We'll give you a clear timeline after the free inspection.
