Is blown-in insulation the right fix for my attic?
Blown-in insulation is loose fill, usually fiberglass, rock wool or cellulose, blown through a hose over your attic ceiling once the gaps are sealed. In Santa Barbara it's the usual way to bring a thin or settled attic back to an even cover that slows heat moving in and out of your house.
Most calls start with a hot bedroom upstairs, a drafty room over the garage or a power bill that keeps climbing, and the attic turns out to have a few tired inches of old fill. The price moves with the size of the ceiling, how much is already up there, how many lights and openings need sealing, and whether the old material is clean enough to stay or needs insulation removal first. The schedule turns on those same things, plus any permit the job needs. The estimate I write up after seeing your attic gives you your own number.
How can you tell your attic needs more insulation?
Hot rooms upstairs
The bedrooms upstairs or the room over the garage stay warm long after the sun goes down. That usually means the attic fill is thin or has settled, and every summer you wait, the air conditioner works harder to keep up.
Joists showing through
You lift the hatch and see the tops of the ceiling joists poking out of the fill, especially near the edges. Those bare strips let heat straight through, and the patchy cover only gets thinner as it settles.
Stains or droppings in fill
Dark patches, matted clumps or droppings in the old fill usually point to an old roof leak or rodents. If new fill goes over it, the problem stays under the new layer, and it all has to come out later.
Work that often goes with it
Home insulation
For a house that's drafty in more places than the attic, so walls, floors and the crawl space get planned together.
Insulation removal
For old fill that's wet, matted or fouled by rodents, cleared out so the new layer starts on a clean ceiling.
How we do blown-in insulation
I start by going up and checking what's already there, because fresh fill over old material that was soaked or full of droppings just keeps the problem. Before the machine comes in, our installers seal the gaps around can lights, pipes, wiring and the hatch, so the new insulation isn't fighting a draft. Then we set baffles at the eaves, short channels that hold an air gap under the roof deck so the vents keep breathing and wind can't push the fill out of place. Last, we blow the fill to an even depth across the whole ceiling and out to the top plate, the framing along the tops of the walls, because the edges are where most attics come up short.
When the old layer is past saving, our insulation removal work comes first, so the new fill goes onto a clean ceiling. And when the attic is only one part of a cold or drafty house, our home insulation service looks at the walls, floors and crawl space too, so each part gets done in the right order.
Topping up clean old fill
This suits attics where the old layer is dry and clean but too thin. We seal the gaps and blow new fill over what's there, which is usually the least costly way to get a full cover.
Clearing out and starting fresh
This suits attics with stains, droppings or fill that's matted down. Taking it out first adds to the job, but it means the new insulation isn't sitting on top of the old problem.
Spray foam when ducts are up there
Foam costs more and seals air while it insulates, so it can earn its price when the ductwork runs through the attic. Otherwise, sealing the gaps and blowing in loose fill usually wins.

I do your estimate myself
I come out for the first look and the estimate, and our installers do the work. I come back afterward to walk the finished attic with you, so the person who planned it is the one checking it.
In business since 2017
We've spent nine years planning jobs so the repairs come before the insulation. That order is what keeps new fill from having to come back out.
Licensed and insured for attic work
We're fully licensed and insured. California's Contractors State License Board lists insulation as its own contractor class, covering any material put in to control heat or sound, so it's fair to ask anyone you hire which license they hold.
We check who covers your address
Around here, an address can fall under a city, the county or the university, and we check which one before we book. When a permit is needed, we apply for it, set up the inspections and tell you how it fits your schedule.
On this job, the order matters most, with fixes and sealing done before any fill goes in. Send us your details or call (805) 284-9538 to set up a look at your attic.
What happens after you call about blown-in insulation in Santa Barbara?
Call or send the form
You call (805) 284-9538 or send the form, and we set a time for me to come out. It helps to mention your attic's rough size and anything stored up there.
I look over your attic
I check how many inches are already up there, the age of the house, and any stains, droppings, open gaps or buried vents. You get a written plan that notes what has to be fixed first, along with the estimate.
We book it in order
Once you say yes, we sort out any permit and line up removal or repairs ahead of the fill. You'll know which part happens when before work day.

Our installers seal the gaps, set the baffles and blow the fill out to the edges. Then I come back, open the hatch with you and go over the finished job.
Common questions
How much does blown-in attic insulation cost in Santa Barbara?
Installing blown-in attic insulation usually runs about $4 to $7.50 per square foot across the US. That's a national average, not a Santa Barbara price and not ours. Your own figure comes from the estimate once I've seen the attic, and every job is backed by our satisfaction guarantee.
Is blown-in insulation cheaper than batts?
Usually, yes. Older Department of Energy guidance says blowing loose fill into an attic is usually less expensive than laying batts and gives better coverage, though installation costs vary. For most attics, it's the sensible option to compare a batt quote against.
Why should you seal the attic before adding insulation?
Because insulation slows heat but doesn't stop air, so gaps left open keep leaking right through it. The Department of Energy notes that recessed lights often sit between the upstairs and the attic, and the gaps around them leak a lot of air. Since insulation goes in after sealing, it's fair to ask any installer to seal those gaps first.
Does Santa Barbara require a building permit for home work?
The City of Santa Barbara generally requires a building permit to build, enlarge, alter, replace, repair or improve a building. Whether your insulation job needs one is worth settling before work starts. As I said above, we check which office covers your address and handle the permit when one is needed.
What causes blown-in insulation to settle?
Mostly, fill that went in too light. Department of Energy guidance says blown insulation has to go in at enough density to protect against settling, which otherwise leaves holes and voids in the ceiling cover. It's a fair question to ask any installer, and I'm glad to go over it at the estimate.
How do I insulate an attic I use for storage?
Raise the storage floor so the full depth of insulation fits underneath it. Older Department of Energy guidance says that when an attic holds storage or equipment, the decking should be raised for full-height insulation below. Mention it when you call so I can look at it during the visit.
