Moreno Valley houses as we find them

Most of what we see in Moreno Valley is tract housing, street after street of stucco homes. Many are two-story with a bedroom or bonus room over the garage, mixed in with older single-story places and newer subdivisions. A lot of our calls here come from owners and property managers looking after rentals, and the complaint is usually the one we hear in French Valley and Perris. The upstairs runs hot, the room over the garage never feels right, and the power bill keeps climbing.

Up top, these houses tend to look alike. The attics are usually wide and shallow, the ducts often run through them, and the insulation is whatever the builder blew in years ago, settled thin and pushed around by every installer who's crawled through since, so the job almost always starts with checking what's there and sealing the gaps.

Insulation work we do on Moreno Valley homes

What we plan for on a Moreno Valley job

Permits for work on existing houses here come from the city's Building and Safety Division, and its permit list doesn't spell out insulation on its own, so before we start I ask them whether your job needs one. If it does, we handle it with them, and their review comes before our crew shows up. Two things are worth checking on anyone you hire. California requires a state contractor's license for most of this work, and the city requires a Moreno Valley business license of every business working here, including ones based outside the city like us.

What moves the price is mostly what I find up top: how big the attic is and how easy it is to get into, how many inches are already there and whether they're clean, how many gaps need sealing, and whether foam makes sense or loose fill will do. The schedule turns on whether old material has to come out first, whether a roof leak needs fixing before anything goes in, and any permit review. I come out to look, explain what I found and put what I'd do in writing, the same way we do next door in Nuevo.

  • If the plan touches the ductwork, the city lists a mechanical permit for altering or relocating HVAC, so that gets settled before any insulation goes over the ducts.
  • If I see water stains on the roof deck, I'll tell you to get the roof fixed before we insulate, because new material over a leak just soaks up the next one.
  • We keep the eave vents open with baffles, small guides that hold insulation back from the vents, so the attic still breathes once the insulation is deeper.
  • Foam costs more and seals air while it insulates, so I bring it up when your ducts run through the attic, and otherwise sealing the gaps and topping up loose fill usually does the job for less.
  • On rentals we work out access with the property manager and tenants ahead of time, since someone has to clear the closet under the hatch and the crew needs the attic to itself.

Questions Moreno Valley homeowners ask us

Does an insulation contractor in Moreno Valley need a California license?

Usually yes, because the Contractors State License Board requires a license when a project needs a building permit, uses any additional workers, or has $1,000 or more in labor and materials across its contracts. Ask any contractor for their state license before you sign anything. We're fully licensed and insured, and I'm glad to go over it at the estimate.

How long does a permit review take in Moreno Valley?

Once all the required documents are in, the city's normal review time is within 12 business days. When your insulation job needs a permit, that review comes before we can start, so I'll tell you where it falls before we set a date.

How long will the crew be in my attic, and when can my family and pets come back in?

That depends on what we're doing up there and what has to happen first, so I tell you at the estimate once I've seen the attic. With air sealing and loose fill, people can usually stay home while we work. With spray foam, everyone, pets included, stays out until the re-entry time in the foam maker's instructions has passed, and we follow those instructions.
