Attic Guard installs and replaces attic insulation for homes throughout Jamul, CA. We hold California contractor license 1138505, we answer the phone 24 hours a day, and we start every project with a free attic inspection. Financing is available.
Jamul runs hot and dry through the summer and cool at night out in the backcountry, and the attic is where most of that comfort is won or lost, so the insulation up there does more work than a lot of homeowners realize.
Heat behaves the same way in every house.In summer the sun loads the roof, the attic turns into an oven, and that heat presses down into your rooms until the air conditioner is fighting a losing battle.In winter the warm air you paid to make rises and slips out the top of the house. Jamul’s inland backcountry climate makes both worse than it is on the coast because the days get hotter and the nights get colder, so the swing your home has to absorb is wider.A properly insulated attic is the barrier that flattens that swing. When the insulation is thin, settled, or missing in spots, you feel it in uneven rooms and a power bill that climbs every July.
Jamul sits in California Title 24 Climate Zone 10, the inland zone, which calls for more attic insulation than the milder coast. Under the state energy code, attics here are generally brought up to about R-38, and R-30 is allowed in some setups where the ducts run inside the conditioned part of the house. R value measures how well the insulation resists heat, so in a place with Jamul’s temperature range you want it on the higher side. Reaching R-38 takes roughly 12 to 14 inches of blown fiberglass, or about 10 to 11 inches of cellulose. We check depth across the whole attic as we install so the coverage is even and you are not left with bare patches over the bedrooms.
A fair number of Jamul homes are older ranch and custom houses on large rural lots, and their attics have insulation that settled years ago or took damage from rodents coming in off the surrounding land. Insulation that has flattened has lost most of its R value, because the loft is what does the insulating. Insulation packed with droppings and urine is a health problem, not just a performance one. In either case we vacuum it out, bag it, and clean the attic deck before new material goes in. If your existing insulation is clean, dry, and still at full depth, we will say so and add over the top instead of charging you for a removal you do not need.
Most Jamul attics do best with blown in insulation because it flows into the irregular spaces around trusses, wiring, and ducts that batts tend to bridge over and leave open. We install blown fiberglass and cellulose, both of which lay down as an even layer across the attic floor. Cellulose is treated to resist fire, which carries weight in a backcountry community like this one, and fiberglass will not burn. Where an attic has clean, evenly spaced joists and easy access, batt and roll insulation is a solid choice, and we use mineral wool when a denser material suits the job. We match the material to your attic during the inspection instead of installing the same thing everywhere.
Insulation slows heat but it does not block air, and Jamul’s older homes often leak air through gaps you cannot see from below. Around recessed lights, the attic hatch, the openings where pipes and wires pass through the ceiling, and the top of the wall framing, conditioned air escapes and drags your heating and cooling with it. We seal those leaks first. On a hot afternoon that keeps attic heat from pouring into the rooms under it, and on a cold Jamul night it keeps your furnace from working overtime. An attic that is insulated but not sealed never performs the way it should, so this step comes standard.
Insulation and wildfire in Jamul’s backcountry
Much of the Jamul area is mapped as high to very high fire hazard, and the 2020 Valley Fire that burned through the hills around Japatul Valley and out toward the Lyons Valley and Deerhorn Valley area is a reminder of how the backcountry can go. Embers, not the wall of flame, are what reach most homes, and they ride the wind into attics through vents. That makes the material in your attic worth thinking about. We install insulation that will not feed a fire, since fiberglass and mineral wool do not burn and cellulose is treated to resist ignition, and while we are up there we point out vent gaps where embers or animals could get in. Hardening a home against fire takes more than insulation, but the attic is a smart place to start.
What attic insulation costs in Jamul and how to pay for it
The price tracks the size of your attic, whether old insulation has to come out first, and the R value you are aiming for. Topping up clean insulation costs less than a full removal and reinstall, and a sprawling rural home takes more material than a smaller house in town. We measure your attic on the free inspection and give you a written price before we start, so nothing is a guess. If you would rather spread it out, financing is available, and income qualified SDG&E customers may be able to get attic insulation at no cost through the utility’s Energy Savings Assistance program. New attic insulation from us also comes with our Energy Savings Guaranteed promise.

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!

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 my attic insulation be in Jamul, CA?
Jamul is in California Title 24 Climate Zone 10, so attics here are usually insulated to around R-38, with R-30 permitted in some duct layouts. Because Jamul gets hot summers and cool backcountry nights, the higher end is worth it for comfort and lower bills. We confirm the right number for your home on the inspection.
Can you add new insulation over my old insulation?
Sometimes. If the existing insulation is clean, dry, and still at a good depth, adding on top is often the smart move and saves you money. If it is wet, matted down, moldy, or fouled by rodents, it needs to come out first. We check before we recommend anything.
Which lasts better in a Jamul attic, blown in or batt?
Blown in usually performs better here because it fills the gaps around framing and ductwork that batts leave open, and Jamul’s older homes tend to have irregular attic spaces. Batt insulation works well in attics with clean, open joists. We look at yours before deciding.
How much does attic insulation cost in Jamul?
It comes down to attic size, whether old material needs removing, and your target R value. You get a written quote after a free measured inspection. Financing is available, we discount 10 percent for military, seniors, and first responders, and income qualified SDG&E customers may qualify for no cost insulation through the Energy Savings Assistance program.
Will better attic insulation really cut my energy bills?
It should. The attic is where most homes gain heat in summer and lose it in winter, so slowing that transfer lets your AC and heater cycle off sooner. Our attic insulation comes with an Energy Savings Guaranteed promise.
How long will the job take?
Most Jamul attics are done in a single day. A simple top up can take a few hours, while a full removal, cleanup, air sealing, and reinstall takes longer. You get a time estimate with your written quote.
