Experienced Insulation Contractor in Norwalk CA - Cooler Rooms Upstairs, Fewer Drafts
Precision Norwalk Insulation Services insulates and air seals attics in Norwalk and the cities around it, including Downey and Bellflower. We also pull out old, dirty insulation in older houses and insulate crawl spaces under cold floors.
What our insulation contractor crew does in Norwalk, CA
Spray foam insulation
Spray foam goes on wet and expands to fill every gap, so it seals air and insulates in one pass, which pays off most when your ductwork runs through the attic. It costs more than loose fill, and we tell you up front the re-entry time, when you, the kids and the pets can come back inside.
Attic insulation
Hot upstairs all summer or cold all winter? We check how many inches are already up there and whether it's dry and clean before we add anything, and we keep the eave vents clear so the attic can still breathe.
Blown-in insulation
Blown-in insulation is loose fill we blow through a hose, and it's usually the most sensible way to top up an attic that's gone thin. We fill the edges as full as the middle, since the edges are where it usually comes up short.
Home insulation
For a drafty house where you're not sure where to start, I look at the attic, walls and crawl space together and write down what I'd do first. The price mostly turns on how much old material has to come out and how much sealing comes before new insulation, and the schedule depends on whether a leak or old wiring needs another trade first, all of which your written estimate lays out.
Insulation removal
When old insulation got soaked by a roof leak or is full of droppings, new material on top just buries the problem. We bag it out and clean up so the new insulation goes onto a sound attic.
Crawl space insulation
Cold floors in a house on a raised foundation usually trace back to the crawl space underneath. We insulate under the floor and seal the gaps around pipes so the rooms above stay warmer.
Wall insulation
We fill the empty cavities in exterior walls, which helps most in older houses built with little or nothing in them. In finished walls we usually fill through small holes and patch them, so the drywall stays put.
Air sealing services
What's air sealing? It's closing the small gaps where outside air leaks in, around pipes, wires, outlets and the attic hatch, and it's usually the first fix we'd suggest for a drafty house.
Basement insulation
We insulate basement walls and the rim joist, the band of framing that sits on top of the foundation, because that's where a lot of outside air finds its way in. It keeps a finished basement drier and easier to heat.
Closed-cell foam insulation
Closed-cell foam is a dense foam that also blocks moisture, so we use it where a wall or floor has to keep damp out as well as hold heat. It costs more than open-cell, and it earns that mostly in damp spots and tight spaces.
Open-cell foam insulation
Open-cell foam is softer and lighter than closed-cell, and it fills odd-shaped spaces and cuts sound between rooms. It's a good fit for the underside of the roof when the ductwork lives up in the attic.
Commercial insulation
We insulate offices, shops and rental buildings for owners and property managers. Our crew is used to working around tenants and keeping everyone informed while the work is underway.
Crawl space vapor barrier
Is the crawl space damp or musty? We lay a heavy plastic sheet over the dirt and tape the seams, so ground moisture stays out of the framing and the insulation above it.
Vapor barrier installation
We put up vapor barriers in walls, attics and under floors where moisture would otherwise work its way into the insulation and framing. Which side it goes on depends on the wall and the house, so we check before we pick.
Attic air sealing
Before new insulation goes into the attic, we seal around the can lights, plumbing, wiring and the hatch from up top. It's the step that usually gets skipped, and it's why some attics stay drafty after a fresh top-up.
Retrofit insulation
Retrofit insulation means adding insulation to a house that's already built and lived in, through the attic, walls or crawl space without tearing the place apart. It's the right call for older houses that went up with very little.
What insulation work looks like
Why Norwalk homeowners call our crew
Underneath comes first
I spent years keeping rental houses in repair, and I saw plenty of attics where someone blew insulation over a roof leak or a bad vent and the owner paid twice. If we find a leak, old wiring, possible vermiculite or a gas appliance that needs checking, we stop and tell you before anything gets covered, even when that means another trade comes first.
I write your estimate
I come out to look at the job and write the estimate myself, and it lists what I'd do and in what order. Our installers do the work with me checking in along the way, so what's on the plan is what happens in your attic.
Licensed in California
California's Contractors State License Board requires a license for anyone contracting work that needs a building permit, uses hired workers or runs $1,000 or more in labor and materials, which covers most insulation jobs. We're fully licensed and insured, and if your job needs a permit, we check with the city or county office for your address and handle the application and inspections.
