What Laguna Niguel's weather means for your attic
Laguna Niguel is a city in south Orange County, and most people here know it from its parks, like the lake at Laguna Niguel Regional Park or the oak and sycamore trails of Aliso and Wood Canyons Wilderness Park in the San Joaquin Hills. The weather is what matters for your house. This county gets long, hot, dry stretches every year, and its Santa Ana winds can reach 70 mph or more. That's when a thin or leaky attic shows up as a hot upstairs and a bigger power bill.
Before we start, I check with the city's Building & Safety Division about your job, since it issues permits for renovations and alterations, and when a permit applies we handle the application and the inspections. The city doesn't require a business license, so the license to ask any contractor about is the state one. California's Contractors State License Board requires it when a job needs a permit, brings in any other workers or runs $1,000 or more in labor and materials, though the board lists some exemptions. We're based here in Laguna Niguel, so this is the weather and the city office we plan around on every job.
Insulation work we do in Laguna Niguel, CA
Laguna Niguel Insulation & Spray Foam is an insulation contractor in Laguna Niguel, CA, with 16 services for attics, walls, crawl spaces and the air leaks between them. Most calls start with a hot room upstairs, cold floors or a power bill that keeps climbing. The price mostly turns on how big the space is and how easy it is to reach, whether old insulation has to come out first, how many gaps need sealing and which material fits. The schedule turns on that same prep, plus a permit when one applies. You'll get your own figure in a written estimate once I've seen the space.
Spray foam insulation
We spray foam into attics, walls and rim joists, where it expands into every gap, so it seals air and insulates in one pass. It costs more than loose fill, so I suggest it mainly when your ductwork runs through the attic. Otherwise, sealing the gaps and topping up what's there usually does the job for less.
Attic insulation
Hot upstairs every afternoon? That usually starts in the attic, so we check how many inches are already up there and bring the coverage up evenly, with as much at the edges as in the middle.
Blown-in insulation
Blown-in is loose fill blown through a hose, so it settles around joists, wiring and corners that batts can't reach. It's often the simplest way to top up an attic that already has some insulation.
Home insulation
When the whole house feels drafty in winter and stuffy in summer, we look at the attic, walls, floors and crawl space together. Then we tell you which one to deal with first.
Insulation removal
We vacuum out and bag old insulation that's been soaked, flattened or filled with droppings, because fresh material laid on top just buries the problem. The attic is cleaned out before anything new goes in.
Crawl space insulation
Cold floors over a crawl space usually mean the underside of the house is open to outside air. We insulate between the floor joists and close the openings so the rooms above stay warmer.
Wall insulation
Can finished walls be insulated? Usually yes, by drilling small holes, filling the cavities and patching them, or by insulating the open studs during a remodel.
Air sealing services
Air sealing means closing the gaps a house leaks through before anything gets insulated, from the room over the garage to plumbing and wiring holes in the walls. It's often the step that does the most for the money.
Basement insulation
We insulate basement walls and rim joists so a below-grade room holds an even temperature. That matters most when the space is a bedroom, an office or a rental unit.
Closed-cell foam insulation
Closed-cell foam is a dense foam that blocks moisture as well as heat. We use it in crawl spaces, basements and anywhere water vapor is a concern.
Open-cell foam insulation
Open-cell foam is softer and lighter, and it fills awkward cavities and quiets sound between rooms for less than closed-cell. We use it in rooflines and interior walls where moisture isn't the worry.
Commercial insulation
For landlords, property managers and small business owners, we insulate rentals, offices and shop spaces. We plan the work around the people who use the building.
Crawl space vapor barrier
We lay a heavy plastic sheet over the crawl space dirt and seal the seams. That keeps ground moisture from rising into the floor framing and the insulation above it.
Vapor barrier installation
Moisture that moves through a wall or ceiling can end up trapped in the insulation, so we add a vapor barrier where the space needs one. If yours doesn't, I'll tell you plainly.
Attic air sealing
Before new insulation goes up, we seal the attic floor around can lights, pipes, wiring and the hatch. We also keep the eave vents clear so the attic can still breathe.
Retrofit insulation
Retrofit insulation means adding insulation to a house that's already built and lived in, through the attic, the walls or the crawl space. It's how most older homes get brought up to date with little or no tearing out.
Why homeowners here call us
See what's in your attic before you decide
I take photos of what's really in your attic, walls or crawl space and explain them in plain words before we talk about a price. You'll know how many inches are up there and whether any of it is wet or full of droppings.
Sealing and repairs first, insulation second
We fix what's damaged and seal the gaps before new insulation goes in, because insulation laid over a draft or old wet material just hides the problem. Doing the work in that order puts your money where it counts.
A smaller job when a smaller job will do
If sealing a few gaps and topping up what you have will fix that hot room, that's what I'll recommend, even when a bigger job is possible. You shouldn't pay to tear out insulation that's still doing its job.
One person from walk-through to cleanup
Whoever walks your job with you, usually me, stays with it through cleanup and the final look. You won't have to explain your house twice to someone who's never seen it.
If you'd like someone to show you what's going on up there, request an estimate and I'll come take a look.
