Attic Guard installs and replaces attic insulation for homes across Alpine, CA. We are a licensed California contractor, license number 1138505, and every job starts with a free attic inspection.
We answer the phone 24 hours a day and offer financing. Alpine sits inland at about 1,800 feet, so attics here bake in summer and lose heat on cold nights. Good insulation is what keeps that swing out of your living space.
Schedule a free inspection with AtticGuard and discover how professional insulation can transform your home’s efficiency and comfort.
When we insulate an Alpine attic we are doing more than blowing in material and leaving. A real job means checking what is already up there, pulling out anything that is wet, matted, or fouled by rodents, sealing the gaps where conditioned air escapes, and then laying in new insulation to the depth your home needs. Some attics only need a top up over clean existing material. Others need a full tear out first because the old batts have soaked up moisture or a rodent problem left droppings and torn paper everywhere. We tell you which one you are looking at during the free inspection, and we show you photos so you are not taking our word for it blind.
East County is rural in a lot of spots, and that means rodents. Roof rats and mice get into attics, nest in the insulation, and leave droppings and urine that soak into the material. Once that happens the insulation is not worth saving. We remove it with commercial vacuums, bag the waste, and clean the deck before anything new goes down. If the mess came from an active rodent problem we can seal the entry points so it does not happen again, and we handle the sanitation so the attic is not a health concern for your family.
Even without rodents, old insulation settles and flattens over the years. Insulation only works when it holds its thickness, so material that has compressed down to half its original depth is not giving you the R value stamped on the bag anymore. Removal and replacement resets that. If your existing insulation is clean, dry, and still holding its thickness, we will tell you a top up is the smarter spend instead of selling you a full removal you do not need.
Most Alpine attics get blown in insulation because it fills around framing, wiring, and the odd angles that batts leave gapped. We install blown fiberglass and cellulose, both of which settle into an even blanket across the attic floor. Cellulose is treated so it resists fire, which matters in a community like Alpine. Fiberglass does not burn at all. For attics with clean, open, evenly spaced joists we also install batt and roll insulation, and mineral wool where a denser material makes sense. During the inspection we look at your attic layout, your framing, and how your home is used, then we recommend the material that fits rather than pushing one product on every house.
Alpine falls in California Title 24 Climate Zone 10, the inland zone that runs hotter in summer and colder at night than the coast. Under the state energy code, attics in this zone are generally brought up to around R-38, with R-30 allowed in certain layouts where the ducts sit inside conditioned space. R value is just a measure of how well the insulation slows heat, and higher is better for a climate with big temperature swings like ours.
To hit R-38 with blown fiberglass you are looking at roughly 12 to 14 inches of depth across the attic floor. With cellulose it lands around 10 to 11 inches. We measure and mark depth as we go so the whole attic reaches target and you do not end up with thin spots over the bedrooms and a pile in the middle. Everything we install is code compliant, and if your project needs a permit through the County of San Diego, we can walk you through what that involves. Alpine is unincorporated, so building falls under County Planning and Development Services rather than a city office.
Attic insulation and wildfire in Alpine’s fire zones
Almost all of Alpine sits in a Very High Fire Hazard Severity Zone, and most of the community is Wildland Urban Interface. Anyone who lived through the 2003 Cedar Fire or the 2018 West Fire that burned near I-8 knows how fast embers move. Embers are the real threat to most homes, and one of the ways they get inside is through attic and gable vents. That is why the material in your attic matters more here than it would in a coastal neighborhood. We install insulation that does not feed a fire, fiberglass and mineral wool do not burn, and cellulose is treated to resist ignition. During the inspection we also point out attic vent gaps and openings where embers or pests could get through, so you know where your home stands. Insulation is one piece of hardening an attic against fire, and we are happy to talk through what we see.
Air sealing that makes your Alpine attic insulation work
Insulation slows heat, but it does not stop air from moving. If your attic has open gaps around can lights, plumbing penetrations, the attic hatch, the spots where pipes pass through, and the top plates of your walls, warm air pours through them and drags your heating and cooling right along with it. We seal those leaks before we insulate. On a hot Alpine afternoon that sealing is what stops your attic from pushing heat down into the rooms below, and on a cold night it keeps the warm air you paid for from floating up and out. Skipping this step is the most common reason a fresh insulation job underperforms, so we do not skip it.
What attic insulation costs in Alpine and how financing works
Price depends on the size of your attic, whether the old material needs to come out first, and the R value you are targeting. A clean top up costs less than a full removal and replacement, and a large custom home out on acreage takes more material than a compact tract house. Rather than guess, we measure your attic during the free inspection and hand you a written price before any work starts. Financing is available if you would rather spread the cost out, and we take 10 percent off for military, seniors, and first responders. Income qualified SDG&E customers may also be eligible for no cost attic insulation through the utility’s Energy Savings Assistance program, and we can point you toward it if you think you qualify. New attic insulation also comes with our Energy Savings Guaranteed promise, so the work is meant to pay you back on your bills.

We couldn't be happier with this service. This company took care of the rats in the attic areas, and filled gaps in the roof/garage/gutters/and vent areas. Service was exactly what we needed. They filled the gaps, blew in new insulation, and repaired a few ducts in the attic that the rats nested in.
We did receive a nice binder from a bigger company but that just showed us they had too much for advertising and we were going with a smaller business for more personal care. AtticGuard's work got rid of the critters, and our rooms are now insulated properly.
We would definitely recommend this company!
Charles Kakuska
These guys should get 6 stars, really. The entire process was perfection, everything they told me was exactly how everything were done and more to the point, I'm so happy with the results. My home is free of rat sounds, etc etc.. It's embarrassing to say this but I should have done this a long time ago. But alls well now. You can not go wrong with this company and may I say that my Technician Mike was amazing. Mike is exactly what all companies want in an employee. The guys that came to do the work also are awesome reps for AtticGuard. Thank you everyone.

Matt and his team were amazing. They removed old and installed new insulation, rodent proofed and sanitized the attic, garage and carport. They were thorough, friendly and patient.
Loui was the best during the inspection and cost estimates. He was really patient in explaining the details of the job and went above and beyond in ensuring all that was discussed when we first met was executed per the agreement.
I highly recommend AtticGuard!

The crawl space and attic insulation services were fantastic! I was worried about drafts and uneven temperatures, but after their work, the difference is night and day. They explained everything clearly and left the areas spotless. Truly a professional job!

We highly recommend this company for anyone who has a problem with rodents in their attic. We had heard some noises that sounded like they were coming from inside the walls near our bedroom. Mike came out on a Sunday to do the inspection - turns out we had a major mouse infestation in the attic. He very thoroughly explained the extent of the problem and the proposed method for remediation. Two days later, Josh and his crew arrived at 8:30 am and began removing the old insulation. The attic was then cleaned and sanitized, and new insulation was blown in. The job was done before 5pm that day. Every step of the process, including the inspection and clean-up was photographed. This company is highly ethical and they take the time to explain everything and answer any questions. There was no upselling - we had some HVAC ducts that needed repair and they included that in the job, rather than trying to sell us new ducts.

I decided to call AtticGuard because they currently have a special promotion of $85 (normally $400) to clean any droppings and rodent proof your attic.
We just moved to Temecula last year and discovered that rats and mice live in the area, so I just wanted to make sure they couldn't gain access to our attic where we used to have all kinds of critters (squirrels, raccoons) back in the state of RI.
Mike came in to inspect and confirmed that everything looked fine. Insulation was up to standard and he made sure there were no tunnels to indicate rodent infestation.
Mike was friendly, courteous, knowledgeable, and informative.
This company doesn't charge fees if no cleanup or additional work other than inspection is necessary. HIGHLY RECOMMEND if you live in a place where there's a lot of wildlife, especially rodents!!

FAQ
What R value should attic insulation be in Alpine, CA?
Alpine is in California Title 24 Climate Zone 10, so attics here are generally insulated to about R-38. Some layouts allow R-30 where the ductwork runs inside conditioned space. Because Alpine gets hot summers and cool nights, staying at the higher end pays off in comfort and on your energy bills. We confirm the right target for your home during the inspection.
Do I need to remove my old attic insulation before new insulation goes in?
Not always. If the existing insulation is clean, dry, and still full and fluffy, we can often add new material on top and save you money. It has to come out when it is wet, moldy, flattened, or contaminated by rodents. We check the condition first and tell you honestly which situation you are in.
Is blown in or batt insulation better for an Alpine attic?
Blown in works best in most Alpine attics because it fills around wiring, framing, and tight spots that batts leave open. Batt insulation makes sense in attics with clean, evenly spaced joists and open access. We look at your attic before recommending either one.
How much does attic insulation cost in Alpine and do you offer financing?
Cost comes down to attic size, whether old insulation needs removing, and your target R value. We give you a written quote after a free measured inspection so there are no surprises. Financing is available, we take 10 percent off for military, seniors, and first responders, and income qualified SDG&E customers may get insulation at no cost through the Energy Savings Assistance program.
Will new attic insulation lower my SDG&E bills?
It should. Most of the heat your home gains in summer comes through the attic, and most of the heat it loses in winter goes out the same way. Proper insulation and air sealing slow that down, so your air conditioner and heater run less. New attic insulation from us comes with our Energy Savings Guaranteed promise.
Does attic insulation help with wildfire risk in Alpine?
Insulation choice is one part of protecting an attic in a high fire area. We install materials that do not burn, like fiberglass and mineral wool, and cellulose that is treated to resist fire. We also flag vent gaps and openings where embers could enter, since those are a common way homes catch during a wildfire. Full home hardening involves more than insulation, and we can tell you what we notice up there.
How long does an attic insulation job take?
Most Alpine attics are finished in a single day. A straightforward top up can take just a few hours, while a full removal, cleanup, air sealing, and reinstall runs longer. We give you a time estimate with your written quote.
