Fast, Reliable Spray Foam Insulation Across Temple City
Spray foam insulation in Temple City runs $2.80 to $5.90 per board foot for closed-cell, and $1.70 to $3.40 for open-cell, depending on attic depth, access, and how much prep work the older framing demands. Most jobs in the 91780 ZIP code are done in one to two days, and we get to Temple City homes quickly from our Laguna Hills location, typically within 24 to 48 hours of a call. If you’re wondering whether your 1940s bungalow off Temple City Boulevard or a postwar tract home near Live Oak Park is a good candidate for foam, the short answer is usually yes, on the attic side. Call (866) 393-6041 and we’ll tell you straight what your specific house needs.
Why Laguna Hills Insulation Is Temple City’s Preferred Spray Foam Insulation Company
Garrett Lund started this company on a simple principle: the right material wins the job, not the product we happen to have sitting on the shelf. That’s why we carry eight manufacturer lines including Icynene, Demilec, Owens Corning, and GreenFiber, covering open-cell, closed-cell, fiberglass, mineral wool, and cellulose. For a Temple City homeowner comparing bids, that means you get an honest recommendation, not a sales pitch for whatever foam a single-line contractor stocks.
Temple City’s housing stock isn’t like newer Orange County tracts. These are 1920s to 1950s California bungalows and small stucco postwar homes, many with low-pitch attics that are genuinely hard to move around in. Our crews know these spaces. They’ve crawled through gable-vented attics with knob-and-tube era wiring, worked around old duct runs, and sealed recessed can lights before any foam goes down. Local knowledge like that keeps your job from turning into an air-sealing failure that a generalist would miss.
We’re licensed and insured, and we’ve built a strong local reputation in Temple City by showing up when we say we will and quoting a price that stands. Estimates are free, and we won’t upsell you into a product that doesn’t belong in your house.
Garage Spray Foam Insulation in Temple City
Garage Spray Foam Insulation in Temple City is one of the most common calls we get, usually because a homeowner’s garage has become an oven by 2:00 p.m. and the attached bedroom above or beside it is a full 10 degrees hotter than the rest of the house. On many Temple City homes, the garage ceiling is an uninsulated attic floor, and heat pours right through the drywall into the living space. We spray closed-cell foam directly on the underside of the garage ceiling or on the attic-side ceiling plane, and the difference is immediate.
Garage Ceilings in Small Postwar Homes
Postwar Temple City tract homes often have garages that were converted to partial living space or now hold home gyms, freezers, and workshop benches. Closed-cell spray foam on the ceiling stops the radiant heat before it builds. In a single-car garage, expect to pay $1,400 to $2,900 depending on square footage and whether we’re also sealing the rim joists.
Rim Joist Sealing in Garages
Rim joists are the biggest air leaks in most garages, including Temple City’s. Closed-cell foam seals the joint where the foundation meets the wood framing, cutting both air movement and insect entry. Rim joist sealing in a Temple City garage typically runs $700 to $1,500, and it’s one of the highest-return air-sealing jobs you can do in this climate.
Closed Cell Spray Foam Insulation in Temple City
Closed Cell Spray Foam Insulation in Temple City is the workhorse for tight attics and garages where every inch matters. It delivers roughly R-6.5 to R-7 per inch, creates an air barrier and a moisture barrier in a single pass, and adds structural strength to older roof decks. For Temple City’s low-pitch 1940s attics where space is limited, closed-cell packs more performance into less depth than any other material.
Low-Pitch Attics and Roof Decks
We spray closed-cell directly on the attic-side roof deck in many Temple City bungalows, turning the attic into a semi-conditioned space. That’s the right call when ducts run through the attic, because the ductwork stops sitting in 140-degree air. Spray foam roof deck applications in Temple City run $4,800 to $9,200 for a typical 1,200-square-foot house, more if old insulation removal and air-sealing are extensive.
Sealing Before You Foam
Here’s the part most homeowners don’t hear from other contractors: in a Temple City vented gable attic, spraying foam without first sealing recessed can lights and old penetrations is worse than doing nothing. The foam traps hot attic air behind it, and those can lights keep pumping heat into the house. We box and seal every can light before foam goes down, then close the gable vents so the attic can dry. Skipping that step is how you end up with a moisture problem in a ceiling that baked for 80 years without one.
Trusted Brands We Service in Temple City
We install and service open- and closed-cell spray foam from Icynene and Demilec, two of the most technically demanding product lines in the industry. If you’re after blown-in cellulose in your Spray Foam Insulation project’s surrounding cavities, GreenFiber is our go-to recycled option. We keep parts, hoses, and material on hand for Temple City jobs, so a small repair or a warranty callback doesn’t wait on a supply house order from Riverside or Pomona. Different brands fit different attics, and we’ll tell you which one fits your specific ceiling plane, not just the one we happen to have on the truck that day.
Common Spray Foam Insulation Problems We See in Temple City Homes
- Original thin batts in 1920s-1950s bungalows. Many Temple City homes off Las Tunas Drive and around Emperor Elementary still have their original fiberglass batt, compressed to paper-thin and doing almost nothing. We remove and replace it, usually with closed-cell foam or a hybrid foam-and-cellulose approach.
- Recessed can lights punching through ceilings. Older Temple City houses have can lights in every ceiling, and each one is a hole in the thermal envelope. If foam goes over unsealed cans, heat and moisture get trapped. We box, seal, and sometimes replace them with IC-rated fixtures before spraying.
- Unsealed gable-vented attics that bake. Vented attics in Temple City’s hot, dry summers reach 130 to 150 degrees. Spray foaming the ceiling plane without closing the gable vents defeats the purpose. We address the ventilation strategy first, then foam.
- Ductwork running through hot attics. Many Temple City houses have old metal ducts with gaps at every joint, leaking cooled air into a 140-degree attic. We seal or re-insulate the ducts as part of a spray foam roof deck job, so the air you paid to cool actually reaches the bedroom.
Pricing for Spray Foam Insulation in Temple City, CA
Here are honest Temple City ranges, not vague estimates. Closed-cell spray foam runs $2.80 to $5.90 per board foot. Open-cell runs $1.70 to $3.40. A garage ceiling in a postwar tract home typically lands between $1,400 and $2,900. A full attic roof deck on a 1,200-square-foot bungalow runs $4,800 to $9,200, depending on how much old insulation removal and air-sealing the job requires. Rim joist work goes for $700 to $1,500. What moves the number most is access: a low-pitch Temple City attic with a 24-inch crawl path costs more in labor than a walkable newer attic, and we’re honest about that.

FAQs About Spray Foam Insulation in Temple City
No. Spray foam must never be applied directly over recessed can lights unless they are IC-rated and you have sealed and boxed them first. In Temple City bungalows with old non-IC cans, we install or retrofit IC-rated housings, seal around them, and only then spray the ceiling plane. Call (866) 393-6041 and we’ll look at your specific ceiling before any foam goes down.
Yes. Most Temple City attics from the 1920s to 1950s are low-pitch, vented spaces with 24 to 30 inches of crawl space at the ridge. Our crews are used to working in them. Closed-cell foam on the roof deck typically works better than blown-in alternatives in these tight attics because it doesn’t need 14 inches of depth to hit code-level R-value. We’ll crawl it, measure it, and tell you if it’s feasible before we quote.
Yes, and it’s often the single highest-impact move you can make. Temple City’s problem is heat gain, not heat loss. Closed-cell spray foam on the attic-side ceiling plane stops the sun from radiating down through your ceiling in July and August. If your house has ductwork in the attic, foam on the roof deck keeps the air inside those ducts from being heated as it travels. Homeowners typically see their upstairs or back rooms stop baking by mid-afternoon after a foam job, especially in older bungalows with attic duct runs.
No, we don’t foam over knob-and-tube wiring, and we don’t foam directly onto old ductwork without addressing it first. Knob-and-tube wiring needs to be evaluated by an electrician; encasing it in spray foam creates a heat trap and is against code. Old metal ducts with leaky seams get sealed or replaced before foam goes near them. We’ll flag these issues on the estimate, and we’ll tell you what needs to happen before the foam crew shows up. Call (866) 393-6041 to schedule an inspection.
Yes, and it’s one of our most common Temple City jobs. We spray closed-cell foam on the garage ceiling, rim joists, and the wall shared with the house. A single-car garage in a postwar Temple City tract home runs $1,400 to $2,900, and you’ll feel the difference same day. It’s a smaller investment than a full attic and returns real comfort if you use the garage as a workshop, gym, or laundry space. Call (866) 393-6041 and ask for a garage-specific quote.
