Insulation Contractor in Mission Viejo - Attics Sealed First, Then Insulated

Quality Aliso Viejo Insulation Services is an insulation contractor based in Aliso Viejo that seals and insulates attics, walls and crawl spaces in Mission Viejo homes for homeowners dealing with hot upstairs rooms and high power bills.

Loose-fill insulation covers an attic floor beneath exposed wooden rafters and a wrapped duct.
A worker in protective coveralls and a respirator uses a large vacuum hose to remove loose insulation from an attic.

Mission Viejo houses and what we find in their attics

Mission Viejo is mostly neighborhoods of single-family homes and townhouses, many built as tracts, so once I've been in one attic on a street I usually have a fair idea what the next one looks like. The calls we get here sound a lot like the ones from Lake Forest and Laguna Hills. It's a bedroom upstairs that won't cool down, the room over the garage nobody wants to sit in, or a power bill that climbs every summer.

In the older attics here we often find a thin layer that's been walked on, soaked by an old roof leak or used by rodents, with the gaps around can lights and the hatch never sealed. That's why a job here usually starts with what's already up there and what has to come out before anything new goes in.

Insulation work we do in Mission Viejo

What to know before insulation work in Mission Viejo

Permits in Mission Viejo come from the city's Building Services office, and whether your insulation job needs one is their call, not ours. We check with them about your job and take care of the permit when one is needed, and since applications and inspections both go through the city online, a permit adds a step before the work and another after it. Mission Viejo doesn't require a business license, so the thing to check about us or any contractor is the state contractor license, and the number for that is in the questions below. We're licensed and fully insured.

The price here mostly comes down to what I find in your attic: how much old insulation has to come out, how many gaps need sealing, how easy the space is to move around in, and whether foam makes sense because ducts run through it. Removal and any permit are what stretch the schedule, and your estimate is where you get your own figure. We drive up from Aliso Viejo for these jobs and do the same work in Costa Mesa, and the order of the work doesn't change from one city to the next.

  • We check how many inches are already up there and whether they're dry and clean, because new material over soaked or dirty insulation just hides the problem.
  • We seal the gaps around can lights, pipes and the attic hatch before any insulation goes down, so it isn't fighting a draft the whole time.
  • We keep the eave vents open so the attic can still breathe, since a buried vent lets moisture collect in the framing.
  • We bring the edges up to full depth instead of piling it in the middle, because the thin spots along the eaves are where the heat gets in.
  • We look at the room over the garage on its own, since it has the garage under it and the attic beside it, and that's usually why it never feels right.

Questions Mission Viejo homeowners ask about insulation

Do I need a permit to insulate my attic in Mission Viejo?

Mission Viejo requires a permit before work that alters or repairs a building, or a regulated electrical, gas, mechanical or plumbing system, so it comes down to what your job touches. The owner or someone the owner authorizes applies online before the work begins. We sort that out with the city ahead of time and handle the permit when your job needs one.

How soon can I get a building inspection in Mission Viejo?

The city does inspections the next business day when the request goes in online before 4:00 PM the day before. When your job has a permit, we put the request in ahead of time so the wait between finishing and inspection stays short.

How do I check an insulation contractor's license in Mission Viejo?

Call the California State License Board at 800-321-CSLB, which is where the city sends residents to check a contractor. You're welcome to look us up before you book anything.

Do we have to leave the house while the attic gets insulated?

Usually not for blown-in insulation and air sealing, though the hallway under the attic hatch gets busy and we keep it covered. Spray foam is different, and everyone, kids and pets included, stays out until the re-entry time the foam maker sets, which is how long before it's safe to come back inside.
