Insulation Contractor in Merced - Cooler Upstairs Rooms and Drier Crawl Spaces

Reliable Merced Spray Foam Insulation is an insulation contractor based in Merced, CA. We insulate and air seal attics, walls and crawl spaces in Merced homes, and we pull out old insulation that's wet or dirty first.

What we find in Merced houses

Merced is home for us. I learned this trade on another crew around town before I started this business, so I've been up in a lot of attics here. The older houses near downtown usually sit over a crawl space and have a few tired inches of insulation up top, often packed down or patchy. The newer subdivisions have the room over the garage that's hot all summer, and ductwork running through an attic that bakes. Then there are the calls about a bedroom that never feels right, and those usually trace back to gaps nobody sealed.

The same mix of houses runs out to Atwater, and the work there looks a lot like the work here. On an older Merced house, the job usually starts under the floor and around the attic hatch. On a newer one, it starts with where the ducts run.

Insulation work we do in Merced

Working in Merced: permits, the weather and what moves the price

When an insulation job in Merced needs a permit, the city's Building Department issues it, and the inspection becomes a set stop in the schedule. I check first whether your address falls under the city or the county, and if the job needs a permit, we take care of it and set up the inspection. We've been in business since 2017, we're licensed and insured, and we stand behind our work with satisfaction guaranteed on every job.

The city's design criteria for building plans use a winter temperature of 25 degrees F, so a house here has to hold heat on cold nights as well as keep a summer bedroom from baking. Price moves with how many inches are already up there, whether old material has to come out first, how many gaps need sealing, how hard the attic or crawl space is to reach, and whether foam or loose fill fits the house. The schedule turns on removal, any inspection and, with foam, the wait before you can come back in. I write all of that into your estimate, the same way we do out in Franklin.

  • Ask any contractor to show you their City of Merced business license, because the city won't take their permit application without one.
  • Tell us which rooms bother you, like the room over the garage or a cold floor, because that's where I start looking.
  • Clear a path to the attic hatch and crawl space door before the estimate so I can get in and take photos.
  • Expect us to keep the eave vents open, because a buried vent stops the attic from breathing and moisture shows up in the framing.
  • If your ducts run through the attic, plan on talking foam, because that one detail usually changes my recommendation.

Tell us which rooms run hot or cold, about how old the house is, and anything you've noticed in the attic or crawl space. We reply within one business day to set a time, then I come out, look the house over, take photos and write up the estimate, which is free and comes with no obligation. Our own crew does the work, and I check it before we call it done.

Questions Merced homeowners ask about insulation

How do I apply for a building permit in Merced?

You apply online through the city's permit system, which is fully electronic, so plans and documents get uploaded there instead of carried in. If your insulation job needs a permit, it's part of what we handle, as we said above.

How much does it cost to insulate an attic in Merced?

I can't give you a fair number until I've seen your attic, because the price turns on what's up there now and what has to happen before anything new goes in. The biggest choice is foam or loose fill. Foam costs more and seals air while it insulates, so it's worth it when your ductwork lives in the attic, and otherwise sealing the gaps and topping up with blown-in usually wins.

Do we have to leave the house while you insulate?

For spray foam, yes, usually, and you, the kids and the pets stay out until the re-entry time is up, which is when it's safe to come back inside. I'll tell you that time before we book the day. For blown-in and air sealing, most families stay home and just keep clear of the hatch.

Can you add new insulation over the old insulation in my attic?

Often, yes, if what's up there is dry and clean, but not if it's been soaked or is full of droppings, because new material on top keeps the damp and the smell in your house. I'll show you photos of what I find. If adding more isn't worth the money, I'll tell you that too.
