Insulation Contractor in Irvine - Attics Sealed and Insulated in the Right Order

Quality Aliso Viejo Insulation Services is an insulation contractor in Irvine, CA. We seal the gaps in your attic first, then add or replace insulation, so hot upstairs bedrooms and the room over the garage are easier to keep comfortable.

What we find in Irvine attics

Most of the Irvine homes I climb into are two-story tract houses built a neighborhood at a time, so the houses on a street often share the same attic layout and the same weak spots. The calls are usually alike too: a hot upstairs, a chilly room over the garage or a power bill that keeps creeping up. Older tracts tend to have a thin, settled layer of blown-in, loose fill that was blown through a hose years ago, while newer ones have more depth but still leak air around can lights, pipes and the hatch. We see a lot of the same houses next door in Laguna Hills.

The shape of these attics drives the job. The roof comes down low at the edges, so the eaves are tight to reach, and that's where older coverage usually runs thin and vents get buried, which is backward from how it should be. I look at the edges, the vents and what's under the old material before I suggest adding anything.

Insulation work we do in Irvine homes

What to plan for on an Irvine insulation job

Permits for work in Irvine come from the city's Community Development Department, which issues them for most construction and repair work the building code covers. Whether your insulation job needs one isn't something I'd guess at, so I check with the city about your job, and when a permit is needed we take care of it and the start date waits on it. Before you hire anyone, you can look up their state contractor's license with the Contractors State License Board and ask about their Irvine business license, since the city requires every business working here to hold one before it starts. We're licensed and fully insured.

What moves the price here is mostly what's already in the attic, starting with whether the old insulation can stay or has to come out first. After that it's how many gaps need sealing, how hard the low edges are to reach and whether foam or loose fill makes sense for your house. The schedule turns on the same things, plus the city's timing when a permit is needed and the wait after spraying foam before you can come back in. Your own figure comes from the quote once I've seen the attic. We've been doing this work out of Aliso Viejo since 2013, and we do the same work up the road in Lake Forest and over in Costa Mesa.

  • If your ducts and air handler sit in the attic, foam on the underside of the roof can earn its higher cost because it pulls them inside the sealed space. If they don't, sealing the gaps and topping up loose fill usually gives you more for the money.
  • If you know how many inches of insulation are up there and roughly when the house was built, tell us when you call, since both tell me what to look for before I go up.
  • Clear a path to the attic hatch, which is often in a closet or the garage, because that's how our crew and the hose get up there.
  • If a re-roof, new can lights or electrical work is coming, let us know, since it's easier to seal and insulate once that work is finished.
  • State rules cap a home improvement down payment at $1,000 or 10 percent of the contract price, whichever is less, so check that on any contract you're handed.

Irvine insulation questions we hear

Do I need a permit to add attic insulation in Irvine?

Call the city's permit question line at (949) 724-6313, or let us ask for you, because whether insulation needs a permit depends on your job. Most construction and repair work the code covers needs one, and the city's guide to which work needs permits notes that even exempt work still has to meet city, county and state codes. When your job needs a permit, we take care of it.

Does an insulation contractor in Irvine need a California license?

A contractor needs a California license whenever the job needs a building permit, uses employees or comes to $1,000 or more in labor and materials. Look the license up before you sign anything, and check the down payment on the contract against the state's limit while you're at it.

Do we have to leave the house while you insulate the attic in Irvine?

With blown-in insulation you can usually stay home, because the work happens up in the attic. Spray foam is different, and you, the kids and the pets stay out until the re-entry time, the point when it's safe to come back in, which we give you for the product we're using before we set the day. How long we're up there mostly depends on whether old material comes out first, and I'll lay out the order of the work at the estimate.

Do I need to remove old insulation before adding more in my Irvine attic?

Only when it's been wet, flattened or full of droppings, because new insulation on top of it just keeps the problem hidden. Clean, dry material can usually stay, and we seal the gaps first before topping it up. If what you have is in decent shape and deep enough, I'll tell you the job isn't worth doing.
