Commerce's older single-story homes and low attics
Commerce is a city where warehouses and industry take up most of the map, and the houses sit in a handful of neighborhoods between them. Much of that housing is older, mostly modest single-story homes with stucco walls, a low attic and either a slab or a crawl space underneath, a lot like what we see next door in East Los Angeles.
That shapes the job. A low attic means our crew works on hands and knees out near the eaves, and that's exactly where coverage runs thin and vents get buried, so I look at the edges before I look at the middle.
What to know before an insulation job in Commerce
The City of Commerce's Building and Safety Division issues building permits for every building in the city, reviews plans and does the inspections, so if your job needs a permit, their review and inspection set part of the schedule. When it does, we pull the permit, book the inspection and keep you posted, and if you're not sure whether yours needs one, we'll help you ask. The city also requires a city business license from anyone doing business in Commerce, contractors based outside the city included, so that's a fair thing to ask any company you're comparing, us included.
Price comes down to what's already in your attic and what shape it's in, whether old material has to come out first, how many gaps need sealing, and whether ductwork up there makes foam worth the extra cost. Removal and a permit both add time, and so does a tight attic hatch. Commerce sits right beside Maywood, so getting a crew here is a short trip, the same as our runs to Cudahy and Bell, and when I come out I'll walk the space with you and explain what I'd do first and why.
What do older Commerce homes need most?
Most of what we find is heat. Inland summers bake a low attic, and when the insulation up there has settled down to a few inches, the bedrooms stay warm well after sundown and the power bill climbs right along with the AC. Before deciding anything, I measure how many inches are already up there and check whether it's clean and dry, because new material laid over a bad layer just buries the problem.
The other thing we see is the room that never matches the rest of the house. A lot of homes here have had a room added or a garage closed in over the years, often with whatever insulation was handy, so we check those walls and ceilings on their own instead of assuming they match.

Insulation work we do in Commerce
Attic insulation
Low attics on older Commerce houses often hold just a few settled inches, so the bedrooms stay hot. We bring the depth up evenly, edges included.
Air sealing services
Air leaking between the house and a hot attic carries your cooled air right out. Our air sealing services close those gaps before any insulation goes down.
Insulation removal
Decades-old insulation here is often flattened, dusty or fouled by rodents. We remove it and clean the attic first, so the new layer isn't sitting on the old problem.
Spray foam insulation
Ducts in a hot Commerce attic lose cooling before it reaches your rooms. Spray foam at the roofline seals and insulates at once, though it costs more.
Crawl space insulation
Raised-foundation houses here often have nothing under the floor, which is why it feels cold in winter. We insulate between the joists from the crawl space.
Commercial insulation
Commerce is full of warehouses and shops, and the offices inside get hot under the roof. We insulate offices and small commercial spaces for business owners here.

Questions about insulation in Commerce
How do I find out if my insulation job in Commerce needs a permit?
Ask the city before the work starts, either by calling City Hall at (323) 722-4805 or by letting us help you ask. If your project goes to plan check, which is the division's review of construction plans, it's checked under the current California codes, including the Building, Residential, Green and Mechanical codes.
How much does it cost to insulate an older house in Commerce?
There's no honest number until I've seen your attic, because the cost depends on what's up there now and which route fits your house. Sealing the gaps and topping up with blown-in insulation, which is loose fill blown through a hose, is usually the lower-cost route and usually the right one, while spray foam costs more and mostly earns it when your ductwork lives in the attic. I'll walk you through both options at the estimate visit.
How long does attic insulation take in a Commerce house?
Sealing and topping up a small attic is usually a short job, and removal is what stretches it, since the old material has to come out and the attic gets cleaned before anything new goes in. I'll tell you how long your house should take when I walk it, and if a permit's needed, the inspection has to fit into the schedule too.
Do we have to leave the house during spray foam, and when can the kids and pets come back?
For spray foam, usually yes, and the foam maker sets the re-entry time, which is how long you wait before it's safe to come back inside. We tell you the wait for the product we're using before the day, so you can plan for the kids and pets. With blown-in insulation and air sealing, most families stay home.
Does the Commerce construction recycling rule apply to insulation removal?
Usually not for a house, because the city exempts detached single-family homes and their accessory buildings unless the building official calls the work a significant remodel or reconstruction. It does cover construction and tenant improvement projects that need a permit, projects of 10,000 square feet or more or worth $10,000 or more, and any demolition or grading, so business owners and landlords with larger buildings should check. Either way, we bag the old material and haul it off.
What causes a Commerce house to stay hot at night even with insulation in the attic?
Usually it's air, not the insulation, slipping in through gaps around can lights, pipes and the attic hatch, so the insulation ends up fighting a draft. Add the thin edges and buried vents I mentioned above, and the attic holds its heat long after sunset. That's why we seal first and insulate second.
