Downey, the city we call home
Downey is where we're based, and you probably know it the way we do: the Columbia Memorial Space Center with its Space Shuttle and space station exhibits, the fishing lakes at Wilderness Park, and the tennis courts at Independence Park. Around those places are the streets we drive every day on our way to jobs.
Most of the homes we go into here are single-family houses with an attic overhead and often a crawl space underneath, along with apartment and condo buildings that property managers call us about. When an insulation job in Downey needs a permit, it comes through the city's Building and Safety Division, and if you're not sure whether yours needs one, we'll find out with you and take care of it.
Insulation contractor services in Downey, CA
Precision Downey Spray Foam Insulation is an insulation contractor in Downey that fixes hot upstairs rooms, cold floors, drafty houses and tired old insulation, with 16 services covering attics, walls, crawl spaces and commercial buildings. The price mostly turns on how big and how easy to reach the space is, whether old insulation has to come out first, how many gaps need sealing, and whether foam or loose fill fits your house. The schedule turns on that same prep, plus a permit when the job needs one. Your free on-site estimate gives you the number for your own house.
Spray foam insulation
Spray foam goes on wet and expands to fill the space, so it insulates and seals air in one step. It costs more than loose fill, and it's usually worth it when your ductwork runs through the attic.
Attic insulation
Hot upstairs all summer? Usually the attic is short on insulation or full of gaps, so we seal those first and then add enough to cover the edges as well as the middle.
Blown-in insulation
Blown-in insulation is loose fill we blow through a hose across the attic floor, so it gets into corners and around framing that batts can't reach. We keep it off the eave vents so your attic can still breathe.
Home insulation
This is for houses where more than one room feels off. We look at the attic, walls and crawl space together and tell you which one to do first.
Insulation removal
Old insulation that got wet or full of droppings has to come out, because new material on top just buries the problem. We bag it, clean the space and check the framing before anything new goes in.
Crawl space insulation
Cold floors usually trace back to an open crawl space under the house. We insulate between the floor joists so the floors you walk on feel warmer.
Wall insulation
Can you insulate walls without tearing them out? In most finished walls we can fill the cavities through small holes and patch them afterward.
Air sealing services
Air sealing means closing the gaps around pipes, wires, can lights and the attic hatch before any insulation goes in. It's the step that gets skipped most, and it's the one we start with.
Basement insulation
For the homes and buildings that have a basement or a below-grade room, we insulate the walls and the rim joist, the wood band sitting on the foundation, so the space feels less damp and clammy.
Closed-cell foam insulation
Closed-cell foam is a dense foam that blocks moisture as well as heat, which makes it a good fit for crawl spaces and spots that see dampness. It costs more than open-cell, so we use it where that moisture protection matters.
Open-cell foam insulation
We spray open-cell foam, a softer and lighter foam, into rooflines and interior walls where moisture isn't the concern. It fills odd-shaped spaces well and quiets sound between rooms.
Commercial insulation
Property managers and small business owners call us for offices, shops and apartment buildings. We plan the work around your tenants and your hours.
Crawl space vapor barrier
A crawl space vapor barrier is heavy plastic laid over the dirt to keep ground moisture from rising into your floor framing. We overlap and seal the seams and run it up the walls so it stays put.
Vapor barrier installation
We install vapor barriers in walls, floors and attics where your house calls for one. Getting it on the right side matters, because a barrier in the wrong spot traps moisture instead of stopping it.
Attic air sealing
Before we add any insulation, we seal the attic floor around can lights, pipes, wiring holes and the hatch. Skip that, and the room below keeps losing air right past the new material.
Retrofit insulation
Retrofit insulation adds or upgrades insulation in a house that's already finished, without opening the whole place up. We check how many inches you have now and what shape it's in before saying what to add.
Why homeowners here call us
You deal with the owner from the first visit
I come out to look at your attic or crawl space and write the estimate myself. I'd rather answer one more question than have you sign off on something you're unsure about.
Problems fixed before they're covered up
We look for soaked or droppings-filled insulation, open gaps and buried eave vents first. That way your new insulation goes into a space that's ready for it.
A plain answer when less will do
If sealing the gaps and topping up what you have fits your house better than foam, I'll tell you so. I'll also say when adding more won't do much for you.
An estimate that shows every step
Your written estimate lists the prep and the sealing along with the install. You can see what you're paying for before you decide.
