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, sealing and insulating in one pass. It pays off most when your ductwork runs through the attic.
Attic insulation
Hot upstairs all summer or cold all winter? We check how deep and dry the existing layer is before adding more, and keep the eave vents clear.
Blown-in insulation
Blown-in loose fill is usually the most sensible way to top up a thin attic, and we fill the edges as full as the middle.
Home insulation
When a drafty house leaves you unsure where to start, I check the attic, walls and crawl space together and write down what I'd do first.
Insulation removal
Putting new material over insulation soaked by a roof leak or full of droppings just buries the problem. We bag it out and clean up first.
Crawl space insulation
Cold floors in a house on a raised foundation usually trace back to the crawl space, so we insulate under the floor and seal gaps around pipes.
Wall insulation
We fill empty exterior wall cavities, which helps most in older houses, and in finished walls we usually work through small holes and patch them.
Air sealing services
What's air sealing? Closing the gaps where air leaks in around pipes, wires, outlets and the attic hatch, usually the first fix for a drafty house.
Basement insulation
A finished basement stays drier and easier to heat once we insulate its walls and the rim joist, where much of the outside air gets in.
Closed-cell foam insulation
Dense closed-cell foam keeps damp out while it holds heat. It costs more than open-cell and earns that mostly in damp spots and tight spaces.
Open-cell foam insulation
Softer and lighter than closed-cell, open-cell foam fills odd-shaped spaces, cuts sound between rooms and suits the roof's underside over attic ductwork.
Commercial insulation
We insulate offices, shops and rentals for owners and property managers, with a crew used to working around tenants and keeping them informed.
Crawl space vapor barrier
Is your crawl space damp or musty? We cover the dirt with a heavy plastic sheet and tape the seams, keeping ground moisture out of the framing.
Vapor barrier installation
We install vapor barriers in walls, attics and under floors to keep moisture out of insulation and framing, checking each wall first to pick the right side.
Attic air sealing
Before new insulation goes in, we seal around can lights, plumbing, wiring and the hatch from above, a step often skipped in attics that stay drafty.
Retrofit insulation
Retrofit insulation goes into a house that's already built and lived in, through the attic, walls or crawl space, which suits older homes built with 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.
