Wall insulation in Monterey Park CA - rooms that stay comfortable and quiet

Rooms that run hot, cold or loud usually have empty walls. Most can be filled through small holes, without tearing out drywall.

How do you insulate walls that are already closed up?

Wall insulation in Monterey Park means putting insulating material inside your home's walls so your rooms hold their temperature and keep more outside noise out. In most homes with closed, empty walls, we fill them through small holes from inside or outside instead of opening them up.

The call usually starts with a bedroom that's cold by morning, a wall that's warm to the touch on a summer afternoon or traffic you can hear from the couch. What your job costs turns on how many walls we fill, which side we go in from, what we find inside them and how much patching follows, and the schedule turns on whether anything has to be fixed first, whether a permit is needed and whether new siding is on the way. When a job needs a permit, we pull it and set up the inspection. I'll look at your walls and give you the figure for your house.

How we do wall insulation

  1. I start by looking at your walls from inside and out, because most closed walls can be filled through small holes and the real choice is which side we go in from. I tell you which side makes more sense for your house, and if new siding is coming, I'll tell you whether to wait for it. On the day, our crew covers your floors and the furniture near the work, drills a small hole into each empty space between the studs, blows loose insulation in through a hose until that space is packed and seals the hole. Then we patch every hole, check that no space got skipped and clean up before we leave.

  2. Insulation does its job better when air isn't sneaking around it, so we often pair the walls with air sealing services, which close the gaps around outlets, windows and pipes before the insulation goes in. If the cold is coming up through the floor more than through the walls, basement insulation may be the better place to spend first.

Why Monterey Park homeowners call Monterey Park Spray Foam Insulation for their walls

  1. I do the estimate myself

    I come out, look at your walls and put the estimate together, then our installers do the work and I go over it with you before we wrap up. You deal with the same person from the first look to the last walk-through.

  2. On my own since 2013

    Before that I spent years doing upkeep for a property management company, chasing hot rooms and drafts somebody else got wrong. That's why I care most about the part you can't see once the holes are patched.

  3. Licensed in California and insured

    California puts this work under its insulation and acoustical contractor classification, and we're fully licensed and insured. Satisfaction guaranteed on every job.

  4. Local, and used to tenants

    We're based in Monterey Park and work in the cities around it across the San Gabriel Valley and the east side of LA County. Landlords and property managers call us too, so we're used to working around people who still live in the house.

If your rooms run hot, cold or loud, call (626) 597-0201 or send us a few details, and have your home's age, which walls feel cold or noisy and any siding plans handy.

Wall insulation questions from Monterey Park

What does wall insulation cost in the Los Angeles area?

Insulating walls in the Los Angeles area usually costs about $1 to $4 per square foot. Where your house lands depends on the material, which side we fill from, how much patching follows and whether anything has to be fixed first. I'll give you the price for your own walls at the estimate.

Can insulation be blown into existing walls through small holes?

Yes, drill and fill is a common way to insulate older homes with empty walls in a mild climate like ours. The installer drills small holes, blows insulation into each empty space and seals the holes, so the walls stay closed.

Is it better to insulate walls from the inside or the outside?

Going in from inside leaves the drainage plane alone, which is the layer behind your outside wall that sheds water, while going in from outside breaks that layer, so it has to be patched or replaced afterward. Which side is right comes down to how easy each one is to reach and what shape that layer is in.

Should I insulate my walls before getting new siding?

If new siding is already planned, it's a good time, because adding a continuous layer of insulation over the bare walls costs only a little more than the siding. Energy Department guidance puts the energy savings payback on that often between 5 and 10 years, and the comfort and quieter rooms show right away.

Does an older home need special care when insulating walls?

If your house was built before 1980, guidance says to be aware of lead safety rules whenever the work disturbs the outside walls, from inside or out. How much of the wall the job opens decides how much those rules matter, so I'll ask your home's age when I come out.

Who can get a permit for wall insulation in Monterey Park?

Monterey Park issues permits for certain work only to people the state licenses for the proper trade, and under certain circumstances a homeowner can get one as an owner-builder. The city requires a building permit to alter any structure apart from a few exempt items, and its list names drywall replacement but not wall insulation, so ask the city's One Stop Building Permit Center, where permits and plans are submitted, whether your job needs one. California's Energy Code also sets efficiency rules for changes to existing homes, and if your job needs a permit, we take care of it.

  • Air sealing services

    Drafts often slip in around outlets, windows and pipes, and full walls won't stop air moving through those gaps.

  • Basement insulation

    A cold floor over a basement can keep a room uncomfortable even after the walls are filled.
