Insulation work on Hemet homes
Hemet sits right next to San Jacinto, where we're based. The houses range from older single-story ranch homes in the older parts of the city to newer two-story tract homes on the edges, with plenty of manufactured-home and senior communities in between. We work the same way just past the city line in Valle Vista and East Hemet, and up the road in Moreno Valley.
Inside city limits, building questions start with the city's Building & Safety Division, which issues permits, reviews plans and makes field inspections. We're licensed and insured, and if your job needs a permit, we pull it, set up the inspections and walk you through what the city asks for. The house itself shapes the rest of the job. Price and schedule mostly turn on how big the attic is and whether old insulation has to come out first, and you'll get your own figure once I've seen it.
Insulation work we do in Hemet
Attic insulation
Most Hemet calls start with the attic, where older houses often have only a few settled inches left. Our attic insulation work brings the coverage up evenly, as deep at the edges as in the middle, once the gaps underneath are closed.
Insulation removal
If an attic's insulation is stained from an old roof leak or full of rat droppings, putting new material on top just keeps the problem in your ceiling. We vacuum the old layer out, bag it and clean up before anything new goes in.
Attic air sealing
Can lights, plumbing pipes, wiring holes and the attic hatch leave gaps that let attic air drift into the rooms below, and older Hemet ceilings tend to have a lot of them. We seal those gaps with foam and caulk before any insulation goes down, so the new layer isn't fighting a draft.
Blown-in insulation
Tract homes on the newer edges of the city often have long, low attics that are hard to crawl through. That's where we use blown-in insulation, loose fill we send up through a hose, because it reaches the far corners, and we put in vent chutes at the eaves first so the fill doesn't bury the vents that let the attic breathe.
Spray foam insulation
In two-story houses where the ductwork runs through the attic, spray foam on the underside of the roof can bring those ducts inside the insulated part of the house. Foam costs more than loose fill, so if your ducts aren't up there, I'll usually tell you that sealing the gaps and topping up loose fill is the better buy.
Commercial insulation
We also hear from property managers and owners of Hemet apartment buildings, offices and shops when tenants complain about hot units or high power bills. We look at the attic, roof deck or walls first, then quote the insulation and sealing that fits the building.
What older and newer Hemet houses need
Many Hemet homes in the older parts of the city were built decades ago, and the attic insulation is often original, packed down thin over the years. Before we add anything, I'll go up and show you what's there. An active roof leak, a wiring splice lying in the insulation or a bathroom fan venting into the attic should be fixed first, and some of that is a roofer's or electrician's job, not ours.
Newer two-story houses usually bring a different call, an upstairs bedroom or the room over the garage that won't cool down while the rest of the house is fine. It's usually thin coverage at the low edges of the attic, gaps nobody sealed, or a garage ceiling with little above it, and I find out which before I suggest anything because each one has a different fix.

Hemet insulation questions
Here are straight answers to common questions about permits, cost and attics in Hemet. If yours isn't here, call or send the form and tell us about your house.
How do I find out if my insulation job needs a permit in Hemet?
Start with the city's "Do I Need a Permit" handout on its forms and handouts page, which is the city's own starting point for planned work. The forms there name other work, such as residential fences, and don't single out insulation, so ask Building & Safety about your project before work starts. If it does need one, we handle the permit for you.
How do I apply for a building permit in Hemet?
Beginning August 11, the city takes all new permit applications through its new online portal, called Tyler. Permits that were already open stay in the city's older system, TrakiT, until they're moved over, so an older permit may still show up there. When we pull the permit for your job, we file it through the portal.
Does the City of Hemet still accept paper plans?
No, the city no longer takes paper plans, so drawings go in for review as digital files through the online portal. For small projects, the city does over-the-counter plan checks, its review of the drawings before a permit is issued. If your job needs a plan check, we'll tell you what files the city wants.
How much does attic insulation cost in Hemet?
The cost of insulating a Hemet attic comes down to how big it is, how many inches are already up there and whether the old layer has to come out first. Sealing the gaps around lights, pipes and the hatch adds to it, choosing spray foam over loose fill raises it, and a low attic that's hard to crawl through takes more labor. I'll give you your own number after I've been up there with a flashlight.
How long does attic insulation take, and do we have to leave the house?
For most loose-fill jobs you can stay home, and the time on site depends on the size of the attic and whether old material comes out first. Spray foam is different, because the foam maker sets a re-entry time, the wait before people and pets come back inside, and we stick to it. I'll tell you which applies to your house at the estimate.
How do I tell if the insulation in my Hemet attic is still doing its job?
Look in from the hatch with a flashlight, and if you can see the tops of the ceiling joists or the layer is patchy, it's too thin to do much. Insulation that's stained, damp, flattened or full of droppings isn't helping either, and it usually has to come out before anything new goes in. If you'd rather not climb up, I'll check it at the estimate and tell you what I see.
