Manhattan Beach has the mix we see across the South Bay, with older one-story houses on small lots sitting next to newer two- and three-story homes that fill most of the lot. In the older ones, the attic often hasn't been opened in years, and what's up there has usually settled, gotten dirty or been pushed aside by past repairs.
The ocean keeps the weather mild, so most calls here aren't about winter. They're about a top floor that won't cool down in late summer, a room over the garage that never feels right, or cold floors over a crawl space on a gray morning.
Send the form or call (424) 254-3847, and we'll reply within one business day to set a time. The estimate is free, done on site at your Manhattan Beach house and comes with no obligation. I walk the house with you, then you get photos of what we found and a written plan that shows what comes first and why.
(424) 254-3847In the older houses here, the usual job starts with attic air sealing, closing the gaps where air slips through, and then blown-in insulation, loose fill blown through a hose, over the top. When the old material is wet or full of droppings, insulation removal comes first, because new fill over a problem just hides it. Houses with cold floors often have a crawl space nobody's been down in, and crawl space insulation is how we warm those floors up. In the newer homes, where ductwork often runs through the attic, spray foam insulation can earn its higher price.
Permits for home work in Manhattan Beach come from the city's Community Development department, and work and inspections can't start until a permit is approved and issued, so on a job that needs one, that wait usually sets the start date. When a job calls for a permit, we handle the application as part of the job. Business licensing there runs through the city's Finance Department, so that's who to ask if you want to check on a contractor working in the city.
The price moves with the attic itself, meaning how big it is, how easy it is to get into, how many inches are already up there, and whether topping up loose fill or spraying foam fits your house. Lots here sit close together, so we work out where the truck parks and where the hose runs before install day, the same way we plan jobs in Hermosa Beach and inland in Gardena. Your own number comes from the walk-through, not a guess over the phone.
I do the estimates myself, and I'll point out what I see as we go instead of asking you to take my word for it. Knowing what's in your attic or crawl space helps you make a good call now and spot trouble later, before anyone picks up a tool.
Foam costs more and seals air while it insulates. In most attics, sealing the gaps first and then topping up loose fill gets you there for less, so that's what I'll recommend. If your ductwork runs through the attic, foam usually earns its price.
Our crew does the install and I check the work on site, so old wet insulation gets pulled before new goes in and eave vents stay clear. We're licensed and fully insured, and the job's backed by our satisfaction guarantee. Call (424) 254-3847 to set up a visit.
Your price comes from what's in your attic, so I give it to you after I've walked the house, not before. Pulling out old material that's soaked or full of droppings adds to the job, and so does sealing a lot of gaps, while a clean attic that only needs topping up keeps it lower. Foam costs more than loose fill, which is why I only suggest it when the house needs it.
How long we're up there turns on how much is there now and whether it has to come out before anything new goes in, and I'll walk you through the order of the work at the estimate. With blown-in insulation, most families stay home while we work. Spray foam is different, because you'll need to be out until the re-entry time, the point when it's safe to come back in, which the foam maker sets, and we'll go over it with you before we start.
Usually it's air leaking in around the edges of the room and insulation that runs thin where the floor meets the outside walls, so the room picks up heat from the garage below and the roof above. Thin coverage at the edges and deep coverage in the middle is backward, and we see it a lot. I'll check those spots at the estimate and show you what I find.
Ask us at the estimate, because we look up what the city asks for at your address and tell you what we found. The city's permit list names re-roofing, window retrofits and plumbing, mechanical and electrical work but doesn't spell out insulation, so we check instead of guessing. If you're re-roofing anyway, that needs a permit, and it's a good time to have the attic looked at before the new roof goes on.
Plans submitted to the city now fall under the 2025 California Building Codes, which the city says are in effect as of January 1, 2026. That matters most when insulation is part of a bigger remodel with drawings, because those plans get checked against the new codes from the start.
