Insulation work around Gardena
Gardena is where we're based, a city with its own building department and plenty of older houses. Mas Fukai Park is the city park people know for its ball fields, basketball courts and play areas, and the Gardena Willows Wetland Preserve is a small piece of wetland the city uses for nature education.
Many of our calls here come from owners of older homes and from landlords and property managers with rentals to keep up. The city requires a business license from anyone who works in Gardena, even contractors based somewhere else, so it's a fair question to ask any company you're thinking of hiring, us included.
Tell us what's going on in your attic or crawl space
We reply within one business day to set up a time for me to come look, and nothing you send commits you to anything. After I've gone through the space with you, you get a free written estimate, with no obligation to go ahead.
About Professional Gardena Insulation Company
Professional Gardena Insulation Company is an insulation contractor based in Gardena, CA, and I started it in 2013 after years in restaurant kitchens and then on an insulation crew.

Insulation contractor services in Gardena, CA
Professional Gardena Insulation Company is an insulation contractor in Gardena, CA, fixing drafty rooms, hot upstairs bedrooms and cold floors, and we serve 12 cities with pages on this site. Price and schedule usually turn on how much old material has to come out, how many gaps need sealing and how easy the space is to reach, and your free written estimate breaks that down step by step.
Spray foam insulation
We spray foam into walls, rooflines and tight spots, where it fills gaps and insulates in one pass, a good fit for awkward spaces.
Attic insulation
Is it hot upstairs? We check what's already in your attic, fix what's wrong underneath and bring the insulation up to an even depth.
Blown-in insulation
Blown-in insulation is loose fill we blow through a hose across the attic floor, a good way to top up thin coverage in older homes.
Home insulation
For owners who want the whole house looked at, we go through attic, walls and crawl space and lay out what each needs, in order.
Insulation removal
When old insulation is soaked, flattened or full of droppings, we take it out first, so new material doesn't sit on top of the problem.
Crawl space insulation
Cold floors usually trace back to the crawl space, so we insulate between the floor joists underneath to help the rooms above hold their warmth.
Wall insulation
We fill empty or thinly insulated walls in finished homes through small openings, or insulate open walls during a remodel before the drywall goes up.
Air sealing services
We close the small gaps where air leaks through your house, around pipes, wiring and doors, so the insulation isn't fighting a draft all day.
Basement insulation
For homes with a basement, we insulate the foundation walls and rim joist, the band of framing where drafts and moisture often get in.
Closed-cell foam insulation
Closed-cell foam is dense foam that blocks moisture as well as air, so we use it where dampness is a worry, like crawl spaces.
Open-cell foam insulation
Open-cell foam is softer and lighter than closed-cell, and we spray it under rooflines and in walls to seal air and fill odd-shaped cavities.
Commercial insulation
Landlords and property managers call us for offices, shops and rental buildings, and we plan the work around tenants and business hours.
Crawl space vapor barrier
We lay a heavy plastic sheet over the dirt floor of your crawl space, so ground moisture stays put instead of rising into the house.
Vapor barrier installation
We install vapor barriers in walls, floors and ceilings where damp air could reach the framing, so moisture doesn't build up behind the finish.
Attic air sealing
Before new insulation goes in, we seal the attic gaps around can lights, pipes, wiring and the hatch, so the air you heat or cool stays below.
Retrofit insulation
Got an older house with thin or missing insulation? We add it to homes that are already built, working around finished walls and stored belongings.

What happens after you call
Call or send the form
Call (424) 292-2987 or send the form with a few words about what you're noticing, like a hot upstairs, a drafty room or a power bill that keeps climbing. We reply to every call and form within one business day to set up a time for me to come out.
We look at it together
I go into the attic, walls or crawl space with you, take photos and explain what I see and the order I'd do the work in. If something like old wiring needs another trade first, I'll say so. Then you get a free written estimate, with no obligation.
Our crew does the work
If you go ahead, my lead installer runs the crew. We cover your floors and belongings, then do the checks and prep before anything gets sealed or insulated. It's the same as a restaurant kitchen, where you prep before you cook, because skipping it shows later.
Walk-through at the end
When the work's done, the lead installer walks you through the finished job and shows you what went in and where. We clean up the work area before we leave, and any question you have about what you're looking at gets a plain answer on the spot.
Your insulation questions answered
How much does it cost to insulate an attic in Gardena?
The price depends on your attic's size, how many inches are already up there and whether old insulation has to come out first, so we quote it after a free look on site. Tight access and the number of gaps to seal also add time and cost.
Is spray foam insulation worth the extra cost?
For most attics, sealing the gaps and topping up loose fill is the better value, because it handles the drafts for less. Foam costs more but seals air while it insulates, so it earns its price when your ductwork runs through the attic.
How long does attic insulation take, and do we have to leave the house?
It depends on the attic's size and how much prep it needs, and I'll give you a realistic idea when I come out for the estimate. Removing old insulation and sealing gaps take longer than a simple top-up. With blown-in and air sealing you can usually stay home, while spray foam has a re-entry time, a wait before you can come back inside, which I'll go over for the product we'd use.
Does an insulation contractor need a license in California?
Yes, for most jobs. The state contractor board requires a license for work that needs a building permit, uses employees or runs $1,000 or more in labor and materials combined, so only small jobs that clear all three may be exempt. We're licensed and insured.
Why do you seal air leaks before adding insulation?
Because insulation slows heat but doesn't stop moving air, so the gaps around can lights, pipes and the attic hatch have to be closed first. Skip that and the new insulation spends its life fighting a draft.
Does your insulation company guarantee its work?
Yes. Satisfaction guaranteed on every job. If anything about the finished work doesn't sit right with you, tell us and we'll talk it through.
Should new insulation go on top of the old insulation in my attic?
Only if the old insulation is dry and clean. If it's been soaked or has droppings in it, covering it just buries the problem, so we take it out first. We also keep the eave vents, the vents along the roof's edge that let the attic breathe, clear and carry the coverage evenly out to the edges, where it often ends up thin.
Do I need a permit to insulate my house in Gardena?
Check with the city before you assume either way. Gardena's Building Services issues permits for most repair and alteration work, and its examples name things like re-roofs and window change outs but don't mention insulation. We find out which office covers your address, the city or the County, and when your job needs a permit, we handle the paperwork, set up the inspections and keep you posted.
