Why It Matters
A Dirty Attic Doesn't
Stay in the Attic
Your attic shares its air with the rest of your home. When rodent droppings, nesting material, and contaminated insulation sit up there, the dust and allergens they shed get pulled into your living space every time the HVAC runs — which is why a neglected attic can mean stale, unhealthy indoor air, odors, and a higher risk of mold and mildew.
Professional attic cleaning removes the source, not just the smell. We clear the droppings, debris, and any contaminated insulation, sanitize and deodorize the space, and can seal the entry points so it stays clean. Pair it with attic decontamination or rodent control when there's an active pest problem behind the mess.
- Healthier, fresher indoor air
- Rodent droppings & debris removed
- Contaminated insulation cleared out
- Lower risk of mold and mildew
- Odors eliminated at the source
- Easier to spot leaks, gaps, and damage
What's Involved
What Professional
Attic Cleaning Involves
Attic cleaning is more than a vacuum and a broom. Here's what a proper, health-focused cleaning covers.
Droppings & debris removal
We remove rodent droppings, urine-soaked material, nesting, and general debris safely, with proper protective equipment.
Contaminated insulation removal
Insulation fouled by rodents or moisture is removed and hauled away — it can't be cleaned, and it degrades your air and R-value.
Sanitizing & disinfection
We sanitize and disinfect the affected areas to neutralize the bacteria and allergens rodents and debris leave behind.
Deodorizing
We treat lingering odors at the source so the musty, unpleasant smell doesn't keep drifting back into your home.
Rodent-proofing & prevention
We can seal the gaps and entry points that let pests in, so your freshly cleaned attic actually stays clean.
Do You Need It?
Signs You Need
Attic Cleaning
Most attic problems announce themselves downstairs. If any of these sound familiar, it's worth a look up top.
Droppings or nesting
Rodent droppings, shredded insulation, or nesting material in the attic are the clearest sign it needs a professional cleaning.
A musty or foul odor
A persistent musty or ammonia-like smell often traces back to rodent waste or contaminated insulation overhead.
Worse allergies indoors
Congestion, sneezing, or irritated airways that ease when you leave can point to allergens circulating from a dirty attic.
Noises or pest activity
Scratching or scurrying in the ceiling means pests — and the mess they leave — are building up above you.
Dusty, stale air
If the whole house feels dusty or the air seems stale, a contaminated attic pulled into the HVAC is a common culprit.
Old, damaged insulation
Compressed, stained, or rodent-damaged insulation belongs out — it hurts both your air quality and your energy bills.
How We Work
Our Attic Cleaning Process, Step by Step
A thorough cleaning is about removing the source and sealing it out — not just tidying up. Here's how we handle every job.
Free attic inspection
We inspect the attic, identify droppings, contamination, and entry points, and confirm exactly what your attic needs.
Remove waste & debris
We safely remove rodent droppings, nesting, and debris — and any insulation too contaminated to keep — and haul it away.
Sanitize & disinfect
We sanitize and disinfect the affected areas to neutralize bacteria and allergens, then deodorize to clear lingering smells.
Rodent-proof the space
We seal the gaps and entry points that let pests in, so your cleaned attic doesn't get re-contaminated next season.
Walkthrough & options
We clean up, walk you through the results, and recommend next steps like new insulation if the old had to come out.

Finding out we had a rodent infestation for the first time was incredibly stressful, but Attic Pros made the entire process so much easier! Jeremy was very knowledgeable when help preparing the estimate and the work that needed to be done. Their team that came to perform the work—Nico Otten, Juan Rodriguez, and Antonio Lopez—were amazing from start to finish. Communication was fantastic right from the beginning. The crew was super fast, highly efficient, and left everything very clean after sanitizing our attic, crawl space, and garage. They definitely gave us total peace of mind. They were also able to finish in one day!!

Our small cottage has a very narrow attic entrance. Denis from Attic Pros was willing to try and was able to enter to clean, vacuum, and replace the old insulation. Very professional, access areas were well shielded and protected. Powerful vacuum and clean up well after themselves.

Tom Best came to our house to give us an estimate on new insulation. He was on time, very thorough and provided a detailed very reasonable estimate within an hour of his visit. What more could you want?

David from Attic Pros was professional, knowledgeable, and thorough. He clearly explained the extent of our rodent problem in the attic and showed us detailed photos and videos so we could fully understand the damage. He took the time to explain exactly what the rodents had caused and walked us through how the repairs would be completed. David was friendly, patient, and easy to talk to, making the entire process much less stressful. We really appreciated his honesty and professionalism.

We cannot say enough good things about Attic Pros! From start to finish, it was a great experience. We initially called for attic, crawl space and duct cleaning, as well as rodent proofing (sealing vents, etc). Samim came out and did a very thorough evaluation, showing us dozens of photos of areas that needed attention. He also recommended new insulation, which we hadn’t considered and told us our dryer vent needed repair. It took us a few weeks to schedule, during which time Samim followed up periodically, never pushy, always answering our questions and providing more info. His professionalism and knowledge was a huge reason why we chose to work with Attic Pros. On the day of the job, Osman and crew cleaned the attic and crawl space and installed new installation, while Douglas repaired the dryer vent and Kevin cleaned the ducts. They did an amazing job sealing off the work areas and keeping the house clean, despite it being very messy and grueling work! They spent about 3 hours vacuuming the attic and another half a day sweeping the crawl space by hand. Their attention to detail was above and beyond what we expected. We were sooo impressed! And Samim’s recommendations were spot on - our dryer is much more efficient now and we noticed the house was cooler within hours of the new insulation being installed (it was the height of summer). We’d use and recommend them again and again!

(800) 543-0382It covers an inspection, safe removal of rodent droppings, nesting, and debris, removal of any contaminated insulation, and sanitizing and deodorizing the space. We can also seal entry points so pests don't get back in and re-contaminate a freshly cleaned attic.
Common signs are rodent droppings or nesting, a musty or ammonia-like odor, worsening allergies or stale air in the home, scratching noises overhead, and old, stained, or damaged insulation. If you notice any of these, a free inspection will confirm what's going on.
It can be. Dried rodent droppings and urine can release harmful particles into the air when disturbed, which is why the work should be done with proper protective equipment and safe removal and sanitizing methods rather than a household vacuum. That's exactly what professional attic cleaning is for.
Yes. Insulation that's been fouled by rodents or soaked by moisture can't be cleaned — it holds contaminants and loses its R-value. We remove and haul it away, and can install fresh insulation afterward if needed.
Both. After removing waste and debris, we sanitize and disinfect the affected areas to neutralize bacteria and allergens, then deodorize to clear the lingering smell at its source — not just mask it.
Most residential attic cleanings are completed in a single visit. Timing depends on the size of the attic, how much contamination and insulation needs to come out, and whether rodent-proofing is included. We'll give you a clear timeline after the free inspection.
It varies by home, but many attics benefit from a cleaning every few years — and sooner any time there's been a rodent problem, a roof or plumbing leak, or noticeable odors or air-quality changes. A quick inspection is the best way to know where yours stands.
Yes. Attics are the shared context across our services — we offer rodent control and attic decontamination alongside cleaning, so we can remove the pests, clean and sanitize the space, and seal it up as one coordinated job.
