Air sealing services in Hemet CA - fewer drafts and rooms that feel the same
Drafty rooms, a hot upstairs or a climbing power bill usually point to hidden air leaks. We find them and close them.
Do I need air sealing, or just a tube of caulk?
Air sealing services in Hemet, CA close the gaps where air slips in and out of your house, around door frames, ducts, fans and the holes cut for pipes, vents and wires, so rooms stop feeling drafty and your heating and cooling stop fighting the outside air.
If one room is always hotter than the rest or the power bill keeps creeping up, the leaks behind it are often up in the attic under the insulation, which is why this work usually goes hand in hand with attic air sealing. The price and the schedule turn on the same few things: how many leaks there are and where they sit, how easy your attic is to get into, how much old insulation has to be moved to reach them, and whether anything has to be repaired before we seal. Your own number comes on the written estimate, once I've seen what's actually up there.
How we handle air sealing in your house
We start by sorting the leaks, because some you can close yourself with a tube of caulk, like a gap around a door frame or under the sink where a pipe comes through, and I'll point those out so you're not paying us for them. The hidden ones are what we go after, around can lights, bath fans, the plumbing vent, wire holes, duct boots and the attic hatch, where they sit under the insulation. We pull back the old insulation, take out any that's soaked or full of droppings instead of burying it, seal the gaps with caulk or foam, weatherstrip the hatch, and keep the eave vents clear so the attic can still breathe. If you have gas appliances, we plan a check on how they vent as part of the job, because a tighter house changes how they draw air. It's like prep in a kitchen, the step nobody sees that decides how everything after it turns out.
Once the gaps are closed, most attics just need the loose fill topped up, with blown-in insulation, loose fill blown through a hose, laid as deep at the edges as in the middle. Foam costs more and seals air while it insulates, so I steer most people toward sealing plus loose fill unless your ductwork lives up there, and then closed-cell foam insulation, the dense kind that also blocks moisture, is worth a look. Air gets in from below too, so if your house has a basement or a below-grade room, basement insulation can belong in the same plan.
Permits and the houses we seal in Hemet
The City of Hemet's Building & Safety Division reviews plans, issues permits and makes field inspections, and whether a given sealing job needs a permit is their call, so that's the office to ask. When a job calls for one, we take care of it with the right city or county office before work starts and plan the work around the inspection.
Around Hemet we climb into a lot of attics where the leaks sit right where other trades cut through, often in houses with a gas water heater or furnace in the garage or a closet. Older houses usually have more of those holes and thin, settled insulation lying on top of them, and newer ones still have gaps where pipes and wires come up through the top plates. We see the same thing on jobs in San Jacinto and Menifee, and we handle it the same way, sealing first and checking the vents.

Questions before you book air sealing
How much does air sealing cost in Hemet, CA?
Air sealing with caulk, spray foam and weatherstripping usually costs about $500 to $1,500 per job across the US, so treat that as a national ballpark, not a Hemet quote. Your price turns on how many hidden leaks there are and how hard they are to reach, and you'll see it on your estimate after I've been in your attic.
Can I seal air leaks in my house myself?
You can handle the obvious ones yourself, like gaps around door frames and holes in the walls where pipes come through. The small, hard-to-find leaks, especially in an attic covered with insulation, are a different job, and pros usually find those with a blower door test, a big fan that pulls air through the house, and a thermal camera that shows where the air moves. If your leaks are up in the attic, plan on a professional look.
Is air sealing safe if I have a gas water heater or furnace?
It is when the appliances get tested, because in some cases a tighter house can make naturally venting gas appliances back-draft, pulling exhaust back inside instead of sending it up the flue. ENERGY STAR advises testing them for proper drafting before and after sealing, and when you have gas appliances we plan that vent check into the job. Home energy assessors can also check how well the house is ventilated, so moisture and harmful gases don't build up.
Is there free help paying for air sealing in Riverside County?
There may be if your household income qualifies. Community Action Partnership of Riverside County offers free energy efficiency upgrades to low-income households through its weatherization program, and county residents with a pre-tax household income at or below 60% of the state median may be eligible. SCE's Energy Savings Assistance program lists weatherization among the free upgrades eligible owners and renters may receive, though it may not be offered in every area, so check with each one directly.
How do I know if my house needs air sealing?
The usual signs are drafty rooms, rooms that never match each other's temperature, and heating or cooling bills that seem high for the house. Dust in the rooms right under the attic and dry indoor air in winter can point the same way. If you're seeing two or three of those, the attic is the first place I'd look.
What is the best order for attic repairs, air sealing and insulation?
Fix the attic's problems first, then seal, then insulate. ENERGY STAR recommends having a professional correct things like wet insulation from a roof leak, moldy or rotted rafters or joists, little or no ventilation, and fans that blow moist air into the attic before any sealing, and EPA recommends finishing the attic air sealing before the insulation. If your attic has one of those problems, budget for the repair as the first step.
