What attic insulation is best? The one that fits your attic.

There's no single best choice for every home. Here's how it usually works out:
- Blown-in cellulose: often the easier fit for an open attic floor with lots of wires, pipes, ducts and odd corners, because it fills around everything. It's our most popular.
- Batts: a good fit where the joist spaces are clear and even.
- We also install blown-in fiberglass.

What matters most is the right type at the right depth. At your free inspection, we recommend the material and R-value that fit your home and list them on your written quote.

Can cellulose insulation get moldy? Not while it stays dry.

The EPA says no mold grows without water or moisture. In a dry attic, cellulose stays dry. Trouble starts when water gets in: a roof leak above, or damp from below in a crawl space.

With the rainy season here, here's what to know:
- Have any roof leak fixed first (we don't do roof repairs).
- Insulation that got soaked should come out and be replaced, so the new layer goes in clean and dry.
- At the free inspection, we look for old leak stains in your insulation.

The cellulose we mainly install, CleanFiber, is made from recycled material.

Barely any air from one vent? Have the ducts checked before assuming you need a new heater.

Our guide covers the warning signs:
• Crushed or kinked duct runs.
• Torn outer jackets with insulation showing.
• Loose connections blowing air into the attic or crawl space.

Weak airflow is a reason to inspect—not an automatic reason to replace everything.

The photo shows new insulated flex ducts from an AttiCali job. When replacement is needed, the normal job is a whole duct system. We don't install heating or cooling equipment.

That white layer under the house has a job: keep ground moisture out of the crawl space air.

This real AttiCali job photo shows a white v***r barrier covering the soil and wrapping the support piers. It's more than a cleaner-looking crawl space. The barrier separates damp ground from the space beneath your floors.

A proper installation starts with cleanup—not laying plastic over debris. Standing water or a plumbing leak needs fixing first; a v***r barrier isn't a drainage repair.

AttiCali EcoShield handles crawl space cleaning, insulation and v***r barriers across the whole Bay Area.

Do radiant barriers work? Yes, in the right attic.

On a sunny day your roof gets hot and beams that heat down into the attic, onto the insulation, the ducts and the ceiling below. A radiant barrier is reflective foil installed under the rafters that turns much of that heat back before it reaches them.

It helps most:
- In hot, sunny inland attics
- When your AC ducts run through the attic
- Together with good insulation, not instead of it

It goes in from inside the attic, and most jobs take one day. At the free inspection we tell you honestly whether it's worth it for your attic, or whether insulation or new ducts should come first.

Add it to insulation or duct work and get 10% off for multiple services, or $300 off jobs over $2,000 (one discount per job).

Old attic insulation? Age alone doesn't mean it needs replacing.

The condition matters:
• Clean, dry, but too thin? Adding insulation may be enough.
• Wet, soiled or damaged? The affected insulation needs to come out before new material goes in.
• Bare patches or flattened paths? Have the coverage checked.

Don't pay for a full replacement just because your insulation is old. Get photos of what's there and a clear recommendation first.

Rats under the house? Here's how to get rid of them for good.

Fall is a good time to check your crawl space, before the rains:

1. Don't sweep or vacuum droppings. The CDC says that stirs germs into the air.
2. Find how they get in: foundation vents, gaps around pipes and wires. Any hole bigger than 1/4 inch is big enough.
3. Seal every entry opening we find with galvanized steel mesh, putty and concrete. Rats chew through softer fillers.
4. Trap the ones already inside. No poison needed.
5. Clean out droppings and soiled insulation, then sanitize. New batts or a v***r barrier can go in the same visit.

Trapping alone won't fix it. Sealing does.
