Why so many San Jose attics need a cleanup
Based on our finished jobs in San Jose, attic cleanup and sanitizing is the second most booked service here, right after rodent proofing. The two often go hand in hand: once rodents have lived in an attic, the ways in need closing and what they left behind needs to come out.
You can also book a cleanout by itself. At the free inspection we point out any open entry points we find, and you decide whether to seal them as well.
Roof rats live up high
The University of California (UC IPM) describes roof rats as agile climbers. Outdoors they nest in trees, shrubs and ivy; indoors they favor attics, wall voids and ceiling voids. That is why the attic is so often where a rat problem starts to show.
What they leave up there is what a cleanout takes away:
- droppings on the insulation, the joists and around the hatch,
- nests built from shredded insulation, paper or fabric,
- runways and tunnels pressed into the insulation,
- insulation stained where the animals lived.
Why you should not sweep it up yourself
According to the CDC, diseases mainly spread from rodents to people when they breathe in contaminated air, and stirring up droppings can put tiny droplets with viruses into that air. The CDC says not to vacuum or sweep rodent urine, droppings or nesting materials, and to bag contaminated insulation in plastic for removal.
That is hard to do well in a cramped attic. In our cleanout, the crew takes out the droppings, nests and soiled insulation, hauls it all away, and sanitizes the attic, so nobody in your home has to handle it. More in cleaning an attic after rodents.
What stays and what goes
Not every attic needs a full strip-out. If the insulation is clean and dry, it can sometimes stay, and the cleanup targets the droppings, nests and debris. Insulation that is soiled, tunneled, wet or flattened comes out. We tell you which at the free inspection.
Old insulation is hauled away by us and listed as its own line on your written quote, so you can see exactly what is being removed. Dead animals found in the attic are removed as part of the cleanout.
After the cleanout: seal, then insulate
A freshly cleaned attic is the right moment to close the ways in and lay new insulation. The order matters: clean out, sanitize, seal the entry openings with galvanized steel mesh, putty and concrete, inside and out, and only then insulate. New insulation laid while the openings are still open gives rodents a fresh place to nest.
We install every insulation type. Our most popular is blown-in cellulose, blown straight onto the attic floor; batts and blown-in fiberglass are options too. See attic insulation in San Jose for R-values, and sealing outside openings for the vents, eaves and roof gaps we close.
The garage and the crawl space too
Rodents that reach the attic often use the garage or the crawl space on the way. Inside the garage we take out droppings and nests and sanitize the area. Under the house, see crawl space cleaning in San Jose. One free inspection covers the attic, the crawl space, the garage and the openings outside, and two or more services get 10% off (one discount per job).
Selling or buying in San Jose?
“Our home inspector said the attic needs cleaning” is something we hear often. If a report flagged droppings or damaged insulation, book a free inspection. You get a written quote with every item listed, usually within 30–60 minutes of the inspection, the same day at the latest.
Job day
Most attic cleaning jobs take one day. Please be home, and clear the path to the attic access of breakable items, like pictures and vases. The crew covers the path from your front door to the attic with drop cloths or plastic sheeting, and our crew sends you before and after photos.
