L&T French Valley Spray Foam Insulation insulates attics, walls and crawl spaces across Temecula, CA. We seal the gaps and add spray foam or loose fill so hot upstairs rooms and drafty spots even out.
Most of our Temecula calls come from the two-story tract neighborhoods that fill the valley, with stucco walls, tile roofs and attics that take a lot of sun. The complaint is usually the same. The upstairs bedrooms run hot, the room over the garage never matches the rest of the house, and the power bill climbs all summer. We also hear from shop and office owners, a few of them in the older buildings around Old Town, and we get much the same calls in Hemet and Menifee.
What usually decides the job here is where the ductwork runs. In a lot of these houses it sits up in the attic with the heat, and that's when I'll tell you spray foam on the underside of the roof is worth its higher cost, because it seals and insulates the space the ducts live in. When the ducts aren't up there, sealing the gaps and adding loose fill over what you have usually does the job for less.
We spray foam onto the underside of the roof or into open walls, where it seals air and insulates at once, so it suits attics that hold ductwork.
Explore serviceIf the upstairs runs hot, I check how many inches are already up there and what shape they're in, then we bring the whole attic up evenly.
Explore serviceBlown-in insulation is loose fill blown through a hose, and it's the usual way to top up an attic once the gaps underneath are sealed.
Explore serviceYou tell us which rooms feel wrong, and we look at the attic, walls and floors together, so the plan fixes the cause instead of one spot.
Explore serviceWe vacuum out old insulation that's been soaked, packed down or full of droppings, because new material laid over it just keeps the problem in your attic.
Explore serviceCold floors over a crawl space usually come from bare framing underneath, so we insulate between the floor joists and seal the gaps around pipes and wires.
Explore serviceWe insulate open walls in an addition or remodel before the drywall goes up, and for finished walls I check what's in there before suggesting anything.
Explore serviceAir sealing closes gaps around doors, outlets, plumbing and ducts across the house before insulation goes in, so the new layer isn't fighting a draft.
Explore serviceBasements are rare here, so when we find one, we check for water first and then insulate the walls with foam that handles damp concrete.
Explore serviceClosed-cell foam is dense foam that also blocks moisture, so we use it where damp is a concern, like crawl spaces, rim joists and metal buildings.
Explore serviceOpen-cell foam is softer and lighter, a good fit for an attic roofline when you want the whole space sealed, and it costs less than closed-cell.
Explore serviceFor shops, offices and rentals, we work around your hours and tenants, and the plan starts with the roof deck, the walls and whatever ductwork runs overhead.
Explore serviceWe lay heavy plastic over the dirt floor and run it up the walls so ground moisture stays out of the framing and floor insulation above.
Explore serviceVapor barriers go on the right side of a wall or floor, or they trap moisture instead of stopping it, so we place them during builds and remodels.
Explore serviceBefore more insulation goes down, we seal around can lights, the hatch and the pipes coming up, since those holes leak attic air into your rooms.
Explore serviceRetrofit work adds insulation to a finished house, working with what's already in the attic, walls and floors instead of opening up rooms that don't need it.
Explore serviceInside Temecula city limits, the city's Building and Safety department handles plan check, permits and inspections, and an address just outside the line can fall to Riverside County instead, so the first thing I do is check which office covers your house. When a permit is part of the job, we handle it with that office, and if it isn't clear whether your job needs one, we ask them before work starts. A permit adds a review and an inspection to the schedule. Before you hire anyone, you can check that they hold a state contractor's license and a Temecula business license.
The price mostly turns on what's already up there. How many inches you have, whether the old material is wet or full of droppings and has to come out, how many gaps need sealing, how easy the attic is to get into and whether foam or loose fill fits the house all move the number. The schedule turns on the same things, plus a roof leak that has to be fixed first. Your own figure comes from the estimate, once I've seen the space. We do the same work just up the road in Murrieta and back home in French Valley.
Tell us what's going on and give us your Temecula address, and we'll reply within one business day. The estimate is free, on site and with no obligation. I come out myself, look over the space, explain what I found and put what I'd do in writing, or you can call (951) 417-1035.
(951) 417-1035Yes. The city requires a business license from anyone doing business inside Temecula city limits, and that includes contractors based somewhere else. Every license expires on January 31, so a contractor's should be current for this year, and you can read the city's business license rules yourself.
Yes, on most jobs. The California Contractors State License Board requires a license when the job needs a building permit, uses any additional workers, or totals $1,000 or more in labor and materials across its contracts. Only a job under $1,000 with no permit, no employees and no claim of being licensed goes without one, and we're fully licensed and insured.
The property owner is responsible for making sure every required inspection is made, though the city lets the contractor schedule them and be there. When we handle the permit, we schedule the inspections and I'm on site for them, with the permit, approved plans and job card at the house as the city requires.
For spray foam, yes. Everyone, kids and pets included, stays out while we spray and until the re-entry time, the wait before it's safe to come back inside, has passed, and I tell you how long that is before we book the day. Air sealing and loose fill jobs usually don't mean leaving home.
