L&T French Valley Spray Foam Insulation is an insulation contractor based in French Valley, CA. We air seal and insulate attics, walls and crawl spaces, install spray foam and blown-in fill, and pull out old insulation that's past saving.
I started out insulating attics for neighbors here in French Valley, and most of the houses I see are newer two-story tract homes, often with the air handler and ductwork up in the attic. Most people who call us own the house and plan to stay, and their complaints sound alike: a hot upstairs by afternoon, a room over the garage that never feels right and a power bill that climbs each summer. We hear the same calls in Temecula and Menifee.
Riverside County gets hot, dry Santa Ana winds every year, and here they leave fine dust streaked across the insulation by the hatch and along the eaves, wherever air has been getting through. That's why I look at the gaps before I talk about depth, since in these houses an open gap keeps pulling attic air into the rooms below no matter how much is piled on top.
We spray foam under the roof deck when your ductwork runs through the attic, so the ducts aren't sitting in summer attic heat.
Explore serviceIf the upstairs bedrooms run hot by afternoon, the attic floor is usually where we start, sealing it first and then bringing it up to an even depth.
Explore serviceBlown-in insulation is loose fill we blow through a hose, and it gets around the wiring and framing in a tract-home attic faster and more evenly than rolls.
Explore serviceWhen rooms all over the house feel off, we look at the attic, walls, garage ceiling and crawl space together and tell you which one to fix first.
Explore serviceWhen what's up there has to go, we vacuum it out through a hose into bags, then clean and seal the attic floor before anything new goes in.
Explore serviceCold floors over a crawl space usually mean the insulation between the floor joists has sagged or fallen, so we put new material back up and fasten it.
Explore serviceWalls on the afternoon side that feel warm to the touch can be underfilled inside, so we fill those cavities through small holes in the wall.
Explore serviceDrafty rooms usually trace back to gaps around pipes, wires and can lights, and air sealing closes those up with foam and caulk before any insulation goes on.
Explore serviceBasements aren't common in the tract houses around here, but where a house has one we insulate the walls with foam that stands up to damp concrete.
Explore serviceClosed-cell foam is dense foam that also blocks moisture, so we pick it for damp spots and tight spots with little room for depth.
Explore serviceOpen-cell foam is softer and lighter, and it's the usual choice under a roof deck when you want the attic sealed and quieter for less than closed-cell.
Explore serviceFor property managers and business owners, we plan the work around tenants and open hours, and walk the building with you before anything gets scheduled.
Explore serviceA plastic sheet over the dirt keeps ground moisture out of the crawl space air, and we overlap the seams and run it up the walls.
Explore serviceNot every wall needs one, so we put in a vapor barrier only where moisture could get trapped, and on the side that keeps it out.
Explore serviceWe seal the attic floor around the hatch, plumbing stacks, wire holes and wall tops before adding depth, so attic dust and heat stay up there.
Explore serviceIf you're keeping the house and want it more comfortable, retrofit work adds insulation from the attic and crawl space so your drywall and floors stay put.
Explore serviceFrench Valley is unincorporated, with no city government of its own, so Riverside County runs things here and the county's Building & Safety Department is the office that issues permits. Its permit list names electrical, plumbing, mechanical and structural repairs and re-roofing, not insulation, so it doesn't settle your job by itself, and when it's unclear I ask the department before work starts. When a permit is part of the job, we handle it with them, and that can add some time before we begin. The county doesn't issue a business license here and has businesses register for its stormwater program instead, so the license worth checking on any contractor is the state one, which the questions below cover.
We do the same work in Murrieta and the other cities around here, and some of them run their own building offices, so I check which office covers your address before we plan anything. The price moves with the size of the attic and how easy it is to get into, how much is already up there and whether it can stay, how many gaps need sealing, and whether foam or blown-in fits. The schedule mostly turns on what has to happen first, like a roof repair, a tear-out or a permit. At the estimate I look it all over, tell you what I found and put what I'd do in writing, so you have your own figure instead of a guess.
Send the form or call (951) 417-1035, and we'll get back to you within one business day to set a time. I come out myself, look over the attic or crawl space, explain what I found and put what I'd do in writing. The estimate is free, at your house and with no pressure to book.
(951) 417-1035Yes, in most cases, because the Contractors State License Board requires a license for work on a building whenever the job needs a building permit, uses any additional workers, or comes to $1,000 or more in labor and materials across one or more contracts. A job done with a crew meets the second test by itself. We're fully licensed and insured, so ask to see it at the estimate.
For most attics here, sealing the gaps and topping up with blown-in is the better buy, and foam earns its cost when the ductwork and air handler live up in the attic. Foam costs more, but it seals air while it insulates, and sprayed under the roof deck it puts those ducts in a much milder space. I'll tell you at the estimate which kind of attic you have, and why.
Yes, for spray foam everyone, kids and pets included, stays out until the re-entry time, the wait the foam's maker sets before it's safe to come back in. I tell you that time before we start, and we keep the house ventilated while the foam cures. With blown-in you can usually stay home.
Usually yes, if what's up there is dry, clean and just thin, and then we seal the gaps and top it up. If it's been soaked, packed flat or full of droppings, it comes out first, because new material over it keeps the smell and the moisture in your house. If I find old material I don't recognize, I'd rather have it tested before anyone disturbs it.
We're based in French Valley and work across the cities around it in southwest Riverside County. These cities have their own pages, and if yours isn't listed, call and ask.
Call (951) 417-1035 any day from early morning until 11 at night, so you can ring us while you're standing under the attic hatch.
If you're not sure what's in your attic, tell us what you're noticing and I'll say what I'd check first.
