Spray foam insulation
We spray foam where it has to stop air and heat together, usually when ductwork runs through the attic. It costs more than loose fill, so I recommend it only when it pays.
Insulation Contractor in South Pasadena, CA - Fewer Drafts in Older Homes
E&J South Pasadena Spray Foam Insulation is an insulation contractor based in South Pasadena. We insulate and air seal attics, walls and crawl spaces in the city's older houses, and clear out old material when it has to go.
Insulating South Pasadena's older houses
I started this business in South Pasadena in 2023, after my early working years on commercial insulation crews. Most of our calls here come from owners of older houses with drafty rooms, a hot upstairs or a power bill that keeps climbing. On the flat streets and the hillside lots alike, I look hard at the attic or crawl space before we talk about materials, because what's up there now and the shape it's in decide most of the job.
The price moves with the size of the space, how easy it is to reach, whether the old insulation is clean enough to stay, how many gaps need sealing and whether foam or loose fill is the right material. The schedule turns mostly on what has to happen first. A roof leak or old wiring should be fixed before anything new goes in, because insulation laid over either one only wastes your money, and if the job needs a permit, the inspection sets part of the pace. My written estimate puts all of that on paper so you can compare it fairly.
We're based here and also work in Pasadena, Alhambra, San Marino and other cities around it. Each one has its own building office and rules, so for a job in South Pasadena I check with the city's Building Division rather than assume a neighboring city's answer holds here.
I write the estimate myself
I come out, look at the space and write the estimate, so the person explaining the work to you is the person who actually saw your attic or crawl space.
Problems fixed in the right order
If the old material is soaked or full of droppings, or the eave vents are buried, I'll tell you before we price new insulation, because covering those problems only hides them.
A walkthrough before we're done
Our install crew does the work, and then I walk the finished job with you, checking the edges, the vents and the hatch, before we call it done.
Insulation work we do in South Pasadena
Attic insulation
Most hot-upstairs calls start in the attic. We measure how many inches are already up there, keep the eave vents clear and make the coverage full at the edges, not just the middle.
Blown-in insulation
Blown-in insulation is loose fill sent through a hose, and it reaches the tight corners of older attics well. We seal the gaps first so the new layer isn't fighting a draft.
Home insulation
When several rooms feel drafty or the power bill keeps climbing, I look at the attic, walls and crawl space together and tell you which one is worth fixing first.
Insulation removal
Old insulation that was soaked or full of droppings has to come out before anything new goes in, or the smell and the problem stay right under the fresh layer.
Crawl space insulation
Cold floors usually trace back to the crawl space. We check for moisture and loose pipes first, then insulate under the floor once the space is ready to hold it.
Wall insulation
Many older walls have little or nothing inside them. We fill the cavities with as little patching as the house allows, and I show you beforehand where any holes will go.
Air sealing services
Air sealing means closing the gaps around pipes, wires, can lights and the hatch before insulating. It's often the step that does the most good, and the one that gets skipped.
Basement insulation
Where a house has a basement, we insulate the walls and the framing along their top edge, where most outside air slips in, so the floor above stops feeling cold.
Closed-cell foam insulation
Closed-cell foam is a dense foam that blocks moisture as well as heat. We use it where dampness is a concern, such as along rim framing or a crawl space wall.
Open-cell foam insulation
Open-cell foam is softer and lighter, and it fills odd roof shapes and wall cavities well. It suits spaces that stay dry, and I'll tell you plainly if yours doesn't.
Commercial insulation
Before starting this business, I spent years insulating offices, warehouses and metal buildings, so property managers get the same planning and order on a commercial job as homeowners do.
Crawl space vapor barrier
We lay a sealed vapor barrier, a heavy sheet over the dirt, so ground moisture stays out of the framing and the insulation above it can do its job.
Vapor barrier installation
A vapor barrier only helps when it sits on the correct side of the insulation. We work out which side that is for your wall, floor or attic before we install one.
Attic air sealing
Before new insulation goes up, we seal around the can lights, pipes, flues and hatch, so warm air stops escaping into the attic through holes the insulation would only cover.
Retrofit insulation
Adding insulation to a finished older house means planning around plaster, wiring and stored belongings. We work out the approach at the estimate, so you know the plan before install day.
Get a written insulation estimate for your house
Send the form or call and we'll reply within one business day to set a time. I come out, look at the space and give you a free written estimate, with no obligation.
An estimate you can compare
The work is written out item by item, so you can set it beside another contractor's quote and see exactly what each one includes before you decide.
Knowing when you can come back
Ask me at the visit whether you'll need to step out. Foam has a re-entry time, the wait before you, your kids and your pets can come back inside, and I'll explain yours.
Licensed, insured and guaranteed
We're licensed and insured, and the work is backed by our satisfaction guarantee, so you know where you stand before anyone climbs into your attic.
Insulation questions from South Pasadena homeowners
These are the permit, license and roof questions I hear most often from South Pasadena homeowners before an insulation job gets started.
Do I need a permit for attic insulation in South Pasadena?
The city's published permit list doesn't settle it, because it names work like plumbing, heating, air conditioning and decks, not insulation. So we check with the Building Division for your particular job. When a permit is needed, we take care of the application and set up the inspection, and I'll tell you at the estimate how that affects the schedule.
Does a re-roof need a permit in South Pasadena?
Yes. The city's guidance says a re-roof with the same material, including roof repair, needs a permit but no plan check or design approval, while switching to a different material needs a permit, plan check and design approval. If your roof leaks, I'll suggest fixing it before we insulate, because wet insulation does you no good.
Does my house being on South Pasadena's historic list affect insulation work?
A historic listing affects only exterior changes, so it matters when the work would touch the outside of the house. About 2,500 properties are on the city's Cultural Heritage Inventory, including most homes 50 years or older, and you can ask the city whether yours is. If a job would change the exterior, I raise it at the estimate.
Does an insulation contractor need a South Pasadena business license?
Yes. The city requires a business license for every person or company doing business inside city limits, and contractors based outside the city must file an application too. That applies to anyone you're considering for work on your house, so it's a fair question to ask alongside their state license.
When does an insulation contractor need a state license in California?
California's Contractors State License Board requires a license when a project needs a building permit, uses any additional workers, or has one or more contracts totaling $1,000 or more in labor and materials. Because we do our installs with a crew, that rule covers every job we take on.
