Air sealing services in Montebello CA - a house that holds the air you pay to cool
Drafty rooms, a hot upstairs or a power bill that keeps climbing? We find the gaps letting air through and close them in the right order.
Do I need air sealing or just more insulation?
Air sealing services in Montebello close the cracks, holes and gaps that let air slip in and out of your house, so the insulation you already have can do its job. Think of insulation as a sweater and air sealing as the windbreaker over it.
Most people call us because a room is drafty, the upstairs bakes all summer or the room over the garage never feels right, and they figure the fix is more insulation. Usually the real trouble is air moving through gaps you can't see under the insulation, and new material laid over those gaps just fights the draft. That's why we seal first, and why attic air sealing is where most of these jobs start.
The price moves with how many leaks there are, how easy your attic or crawl space is to move around in, and whether old insulation that's soaked or full of droppings has to come out first. The schedule turns on what we find, because a roof leak or old wiring gets fixed before anyone seals over it, and on any permit the job needs. Your written estimate tells you what we'd do for your house and in what order.
- Gaps around can lights, pipes, wires, bath fans and the attic hatch get sealed.
- We work the attic floor, the crawl space and the wall between the house and garage.
- You get a plain answer if sealing alone won't fix the problem you called about.
What happens when you call us about air sealing in Montebello?
Every job starts with someone actually going into the space, because the right fix depends on what's up there. Here's who does what, from your first call to the walk-through at the end.
Call or send the form
Call (213) 491-1019 or use the form, and we set a time to come out and look at the space in person. We're open 7 a.m. to 10 p.m., seven days a week.
We look at the space first
I or our lead installer goes into the attic, walls or crawl space and writes down anything that has to be fixed first, like a roof leak or a soaked patch of insulation. You get a written estimate that says what we'd do and in what order, so you can see what's worth paying for before you commit to anything.
Check permits, then seal
Before we start, we check with the building office that covers your address, and then our own crew does the work. The City of Montebello allows construction from 7 a.m. to 8 p.m. on weekdays and 9 a.m. to 6 p.m. on weekends and holidays, so a job that runs more than a day is scheduled inside those hours.
Walk the finished job together
When we're done, our crew walks the job with you and shows you what we sealed and which vents we left open on purpose. If something doesn't look right to you, that's the time to say so.

(213) 491-1019Air sealing questions we hear in Montebello
These are the questions Montebello homeowners ask us most about sealing air leaks. If yours isn't here, call and ask, and we'll give you a straight answer.
Can I seal air leaks in my house myself?
Yes, for the obvious ones, like gaps around door frames and the pipes, vents and wires that run through outside walls. Small leaks that are hard to find, especially in the attic under layers of insulation, are where doing it yourself stops working, and that's the part we handle.
How much does air sealing cost near Montebello?
An insulation project with air sealing in the Los Angeles area usually costs about $1,200 to $5,800 per job. That range covers the sealing plus the insulation work around it, and it's the going rate in the area, not our quote. Your written estimate gives you the number for your house.
Is air sealing safe if I have a gas water heater or furnace?
It is when the job is planned around those appliances, so their exhaust still leaves the house. Weatherization guidance calls for a worst-case draft test, a check that combustion fumes leave the living space, before and after the work and at the end of each workday on jobs longer than a day. Any duct that brings combustion air to the appliance stays open, and as we said above, we go over your gas appliances with you before sealing.
How do I find out where my house is leaking air?
Professional energy assessors find leaks with a blower door test, a big fan set in a doorway that pulls air in through the gaps, and a thermal camera that shows where air is getting through. They also check how well the house is ventilated so water vapor and harmful gases don't build up. If you're having the test done and have vinyl flooring that isn't glued down, mention it first, because the fan has been known to lift it and can pull in some dirt and pollen.
How long does air sealing take, and do we have to leave the house?
The time turns on how many leaks we find and whether old insulation has to come out first, so your written estimate lays out the plan before we start. Most caulk and board work lets you stay home, and if any part of the job means you should step out, we tell you at the estimate when you can come back.
What license does an air sealing contractor need in California?
If the job includes insulation, look for a contractor in the state's insulation class, because California's license board puts installing insulation under that class. The weatherization class covers weather stripping and caulking around doors and windows, but not insulation. We're licensed and fully insured.
