La Crescenta-Montrose and its added-onto older homes
We're an insulation contractor based in Glendale, CA, and La Crescenta-Montrose sits right above us against the foothills, so it's one of the places we get to most. It's mostly houses, plenty of them older and added onto over the years, a lot like what we see in Altadena. Many of our calls here come from folks who just bought one of those houses and want to know what's really in the attic before they spend money on it.
Those additions are what shape the job, because the original house, the newer room and the room over the garage were often insulated at different times or not at all, so we look at each part before we price anything.
Working in La Crescenta-Montrose, on the county side of the valley
La Crescenta-Montrose is unincorporated, so Los Angeles County handles what a city would, and when an insulation job here needs a permit, LA County Public Works is the office that issues it. Part of the valley sits inside the City of Glendale, so we look up your address or parcel number on the county's Service Locator to see which office covers your house, and if a permit's needed, we pull it, line up the inspection and put in writing who's handling it. Before you hire anyone, check their state contractor's license, and their County Business License if they're based in unincorporated LA County and the county requires one for their work.
The price mostly turns on what we find, because an attic that just needs sealing and a top-up is a smaller job than one where old insulation has to come out first. The schedule turns on our calendar and whether the county has to inspect. Our crew comes up from Glendale for jobs here the same way it heads over to La Cañada Flintridge, and you'll get your own number from the estimate once I've seen your house.
What do older La Crescenta-Montrose houses usually need?
Older houses here often have only a few inches of insulation up in the attic, packed down over the years, with gaps around the can lights, the pipes and the attic hatch that let air straight through. More insulation on top won't stop a draft, so we do the air sealing first, closing those gaps with foam and caulk, and then bring the insulation up evenly all the way out to the edges, where it's usually thinnest.
Under the house, an empty crawl space is why so many rooms here have cold floors. If the old insulation down there or in the attic is wet or full of droppings, we take it out first, because covering it up just keeps the problem in your house.

Insulation work we do in La Crescenta-Montrose
Attic air sealing
Attics in the older houses here usually leak air at the can lights, the pipes and the hatch, and insulation can't do its job with a draft running through it. We seal those openings before anything else goes in, so the insulation on top actually holds.
Insulation removal
When we find insulation that got soaked from an old roof leak or is full of droppings, it has to come out before anything new goes down. We vacuum it out, clean up the space and show you what caused it, so the new material isn't sitting on the same problem.
Blown-in insulation
Most attics here just need topping up, and blown-in insulation, loose fill sent through a hose, gets around the framing and into the low corners better than batts do. We bring it up evenly to the edges and keep the vents at the eaves clear so the attic still breathes.
Crawl space insulation
Plenty of houses here sit on raised floors over a crawl space, and when nothing's under the floor, you feel it in cold floors. We check the crawl space for moisture first, since insulation that stays damp down there won't last, and then insulate between the floor joists.
Wall insulation
Older walls and the room over the garage are often empty or close to it, which is why one room runs hot or drafty while the rest of the house feels fine. Our wall insulation work usually fills those cavities through small holes we patch afterward, so you don't have to open up the walls.
Spray foam insulation
Foam costs more, but when your ductwork runs through the attic, sealing the roofline with foam is usually worth it because it seals air and insulates at the same time. When the ducts aren't up there, I'll tell you that sealing the gaps and topping up with loose fill is the better spend.
How it goes when you call us from La Crescenta-Montrose
Call and tell me what's happening
Most of the time I pick up myself when you call (747) 372-8156, and we find a time for me to come out. Tell me what you're noticing, like a hot upstairs, cold floors or a big power bill, so I know where to look first.
I look up there with you
My dad taught me to look before I price anything, so I go up in the attic or under the house with a flashlight and walk you through how many inches are there, whether it's damp or dirty, and where air gets through. Then I write up your estimate, so you know the cost before anyone starts and which parts aren't worth paying for.
Our crew does the work
Our crew lead and installers seal the gaps first and insulate after, keeping the eave vents clear as they go. If the county requires a permit for your job, we set the inspection around the work so it doesn't hold you up.
We check it over together
When the crew's done, I come back and look over the work with you before we pack up, so you can see the depth and the sealed gaps for yourself. Your satisfaction, guaranteed.

Insulation questions from La Crescenta-Montrose homeowners
Does insulation work in La Crescenta-Montrose need a permit from LA County?
The county's list doesn't settle that for insulation by name, so we check with the county for your address before we start. The LA County Public Works permit list covers building new, additions or alterations, repairs or replacements, and installing or upgrading electrical, plumbing or mechanical systems. If your job turns out to need one, we pull it.
How long does an LA County building permit stay active?
A county permit stays active as long as the first inspection is requested within 12 months of getting it and follow-up inspections come every 6 months after that. An insulation job moves a lot faster than that, so we line up the inspection with the work instead of letting the permit sit.
How do I check that an insulation contractor is licensed in California?
You look the contractor up with the Contractors State License Board, which licenses contractors in California. The state requires a current license for any job that needs a building permit, for anyone using employees, and for any job worth $1,000 or more in labor and materials combined. We're licensed and insured, and we're happy to show you before you sign.
How much can a contractor ask for as a down payment in California?
Under the state's rules, a down payment on a home improvement job can be no more than $1,000, and less than that on smaller contracts. Every payment after that has to be spelled out in the contract and tied to work done or materials delivered, which is worth checking on any bid you get.
How much does it cost to insulate an attic in La Crescenta-Montrose?
The cost comes down to what's up there now, because sealing and topping up a clean attic is a much smaller job than pulling out soaked or dirty insulation first. The size of the attic, how easy it is to get into, and whether ducts in the attic make foam worth it move the price too. You'll get your own number from the estimate after I've been up there.
Do we have to leave our La Crescenta-Montrose house while you insulate?
Usually not for air sealing and blown-in insulation, since that work stays up in the attic and you can go about your day. Spray foam is different, because everyone, kids and pets included, stays out until the re-entry time the foam maker gives for when it's safe to come back in, and we'll tell you that before we book the day.
