Questions, answered.

Can I book cleaning only?

Yes. You can book cleaning on its own. At the free inspection we also show you any open entry points, so you can decide whether to seal them too.

Do you replace the insulation after cleaning?

If you want it, yes: any type of insulation you want, listed on the same written quote. Our most popular is fresh cellulose.

How is it priced?

We price it after the free inspection, and the written quote lists every item. 10% off for multiple services, or $300 off any job over $2,000 (one discount per job).

How long does attic cleaning take?

It is a one-day job.

Do you sanitize the attic?

Yes. After the droppings, nests and soiled insulation are out, the crew sanitizes the attic.

What R-value goes back in?

Any R-value you choose, and we recommend one at the free inspection. The most common in attics is R-38.

How do you protect my home on job day?

The crew covers the path from your front door to the work areas with drop cloths or plastic sheeting: the floors, and some walls where needed. Old material and debris go out with us.

Yes. AttiCali EcoShield is licensed, insured and bonded. California contractor license #1149346 (C-2 Insulation, C-20 HVAC).

Do I need to be home on the job day?
