Insulation work, up close
Insulation contractor in Murrieta, CA, from attic to crawl space
Premier Murrieta Spray Foam Insulation is an insulation contractor in Murrieta, CA, and we handle 16 kinds of insulation work, from the attic down to the crawl space. Most calls start with a room that won't stay comfortable or a power bill that doesn't add up. The price mostly turns on the size of the space, whether old insulation has to come out first, how many gaps need sealing and whether foam or loose fill makes sense for your house. The schedule turns on what we find, because a roof leak or old wiring gets fixed before anything new goes in. The written estimate after our look spells out both for your house.
Spray foam insulation
Spray foam goes on wet, expands into cracks and sets in place, so it insulates and seals air in one pass. It suits rooflines, rim joists and odd spaces where loose fill won't stay put.
Attic insulation
Hot upstairs, or a power bill that keeps climbing? We check what's already up there, seal the gaps, keep the eave vents clear and bring the insulation up evenly, right out to the edges.
Blown-in insulation
Blown-in insulation is loose fill we blow through a hose across the attic floor. It's the usual way to top up a thin attic without tearing anything out.
Home insulation
When the whole house runs drafty or uneven, we look at the attic, walls and floors together and work out which one is costing you the most comfort before we suggest anything.
Insulation removal
Old insulation that got soaked or is full of droppings has to go, so we vacuum it out and clean up before anything new goes in, and the problem doesn't stay buried.
Crawl space insulation
Cold floors over a crawl space usually mean the space below is bare or the old batts have fallen down. We insulate under the floor so the rooms above feel warmer underfoot.
Wall insulation
We add insulation to existing walls that were left thin or empty, usually by filling the cavities through small holes we patch afterward instead of opening up the drywall.
Air sealing services
Air sealing means closing the gaps around pipes, wires, can lights and the attic hatch before we insulate, so your insulation isn't fighting a draft. In a drafty house it's often the first thing we'd do.
Basement insulation
Got a basement or lower level that stays chilly? We insulate its walls and rim joist so the space is comfortable enough to actually use.
Closed-cell foam insulation
Closed-cell foam is a dense spray foam that blocks moisture as well as heat. We use it in crawl spaces, rim joists and spots that see damp.
Open-cell foam insulation
Open-cell foam is a lighter, softer spray foam that fills rooflines and wall cavities and quiets sound. It fits where moisture isn't the concern and you want air sealing along with the insulation.
Commercial insulation
For property managers with offices, shops or rental buildings, we put together a careful plan that works around tenants and how the building is used.
Crawl space vapor barrier
A crawl space vapor barrier is a heavy plastic sheet laid over the dirt and taped at the seams, so damp ground stops feeding moisture into the floor above.
Vapor barrier installation
We install vapor barriers in walls, ceilings and other spots where moisture could otherwise work its way into the insulation and the framing behind it.
Attic air sealing
Before the attic gets more insulation, we seal the holes in its floor around can lights, pipes, wiring and the hatch, so house air stops leaking up and attic dust stops coming down.
Retrofit insulation
Is your house short on insulation? Retrofit insulation adds it to the attic, walls or floors you already have, with no remodel.

The owner from the first look to the walk-through
I write every estimate myself and work alongside our crew on the install. What we talked about in your kitchen is what gets done in your attic.
The cause gets fixed before insulation goes in
We look for what's behind the problem first, like a roof leak, old wiring or damp ground. I'd rather tell you a job isn't ready yet than bury a problem under new material.
Plain answers, even when insulation isn't the fix
We explain what we found in everyday words and why we'd do each step, so your house makes sense to you. If the real issue is something else, we say so instead of selling you insulation.
Even coverage to the edges, vents kept clear
We keep the insulation as deep at the edges as in the middle and keep the eave vents open. That way the attic can still breathe and moisture doesn't show up in the framing later.
Questions about insulation in Murrieta, answered
How much does insulation cost in Murrieta, CA?
It depends on your house, so I give you a written figure after a free on-site look instead of a guess over the phone. The size of the space, how much old insulation has to come out and how many gaps need sealing move the price most.
Is spray foam worth the extra cost over blown-in insulation?
For a plain attic floor, usually not, because sealing the gaps and topping up loose fill gets you most of the benefit for less. Foam costs more but seals air while it insulates, so it earns its keep when your ductwork runs through the attic.
How long will the crew be in my attic, and when can my family come back inside?
That depends on the size of the space and whether old insulation comes out first, and I'll tell you before we start. With blown-in insulation you can usually stay home, while spray foam means everyone, pets included, stays out until the re-entry time, the wait the foam maker sets before people come back inside. If the job needs a permit, the city says its review currently takes about 15 business days, so that wait comes before we start.
Are you a licensed and insured insulation contractor in Murrieta?
Yes, we're licensed and insured. The City of Murrieta also requires a business license to work inside city limits, and that license goes on any permit application, so it's a fair thing to ask any contractor about.
Do you remove old insulation before adding new?
Only when it needs to come out, like when it's been soaked or is full of droppings, because new material over that keeps the problem in your attic. Clean, dry insulation can usually stay, and we add to it after sealing the gaps.
Do you guarantee your insulation work?
Your satisfaction, guaranteed. Before we leave, we check the work against the plan we agreed on and walk you through it, so you can see what was done and ask about anything that doesn't look right.
How do I know if my attic needs more insulation?
Look at how many inches are up there and whether it's even, because thin edges, matted or stained spots and gaps around the hatch are the usual signs. On our visit I measure it and show you what I see, including any spots where the house's age or an old repair left it short.
Do I need a permit for insulation work in Murrieta?
It depends on the job, so when it isn't clear, we check with the city's Building and Safety Division before we start. When a permit is needed, we take care of the application and line up the inspections, so you're not left guessing.
