We’re Orange County Insulation, an insulation-only contractor led by Noel Carrasco. We don’t do roofing, we don’t do HVAC, we don’t do remodeling. We do insulation. That single-trade focus matters in Artesia because so many homes here hide problems a generalist would miss.
Why Orange County Insulation Is Artesia’s Preferred Spray Foam Insulation Company
Artesia homeowners call us for one consistent reason: the houses here were built before insulation was standard practice, and the fixes require someone who understands what’s actually inside those walls. We stock and install products from eight manufacturers including Icynene, Demilec, and Owens Corning, so the material we recommend is the right one for your specific situation, not the only one we happen to carry.
Noel Carrasco built this company around a simple idea: if you only do insulation, you get better at insulation. Every crew member who works in Artesia has spent years opening walls, mapping cavities, and correcting what previous generalists left behind. When a converted garage in 90701 has peeling paint on the inside of an exterior wall, our team knows that’s a moisture signal, not a paint problem. That kind of pattern recognition comes from doing this work hundreds of times in this specific housing stock.
Our customers across Artesia consistently mention the same things: we show up when we say we will, we explain why one foam type beats another for their walls, and we leave the job site clean. We’re licensed and insured, and we offer free estimates with no pressure.
Spray Foam Insulation Contractors in Artesia
Spray foam insulation contractors in Artesia do work that looks very different from what contractors in newer cities handle. Here, we’re usually sealing and insulating cavities in wood-frame homes built between 1950 and 1970, many with original wall construction and minimal insulation. A typical open-cell spray foam application in a 1,200 – 1,500 square foot Artesia home runs $1,800 – $3,900 depending on cavity depth and access. Closed-cell jobs, which add structural strength and a vapor barrier, typically run $2,800 – $4,600 for the same footprint.
Converted Garage Cavities
The dense tract blocks off 90701 routinely contain garages converted to living space with zero insulation. The morning marine layer leaves those uninsulated cavities damp and cold year-round, and that moisture shows up as peeling paint on the inside of exterior walls. We map these irregular spaces fully before spraying, and we seal any old exterior penetration that’s letting damp air bleed in.
Rim Joist and Band Areas
In 1950s wood-frame construction, the rim joist where the floor meets the foundation wall is almost never sealed. We see this in nearly every Artesia home we open up. Closed-cell Demilec foam works well here because it air-seals and provides a moisture barrier in one pass, stopping the air movement that makes rooms along exterior walls feel drafty even when the thermostat says otherwise.
Spray Foam Attic Insulation in Artesia
Spray foam attic insulation in Artesia is where we see the biggest temperature swings in the county. Summer sun pushes attic temperatures above 120°F even with the marine layer burning off by noon. A typical attic air-seal and open-cell foam application in Artesia runs $2,200 – $4,200 for homes under 1,500 square feet. Larger attics or closed-cell applications run higher, up to $5,500 for a roof deck treatment on a bigger home.
Attic Floor and Duct Chase Sealing
In Artesia’s 1950s and 60s homes, attic floors are full of gaps around ceiling fixtures, plumbing vents, and wiring penetrations. The air you’re paying to cool or heat leaks straight through those gaps into an attic that’s 130 degrees in August. We seal those penetrations first, then apply foam at the specified depth so the barrier is continuous, not patchy.
Roof Deck Applications
Some Artesia homeowners want the attic brought inside the thermal envelope, especially when the attic holds HVAC equipment or ductwork. Applying Demilec closed-cell foam to the underside of the roof deck in these homes keeps the attic space within a few degrees of living space. It costs more than an attic floor job, but the energy math often works out within a few years for homes with ducts in the attic.
Trusted Brands We Service in Artesia
We install open-cell spray foam from Icynene and closed-cell spray foam from Demilec, which gives us two specialized product lines instead of hedging on one. We also work with Owens Corning and GreenFiber for blown-in applications when a customer’s attic or wall cavity calls for that method instead. Having eight manufacturers on the roster, including Rockwool and CertainTeed, means we’re never forced to steer an Artesia customer toward whatever roll happens to be on the truck. We stock materials for both 90701 and 90702 service calls, so turnaround on a materials reorder is typically a day or two, not a week.
Common Spray Foam Insulation Problems We See in Artesia Homes
- Uninsulated converted garages trapping marine-layer humidity. The dense 1950s tract blocks off 90701 routinely contain garages converted to living space with zero insulation. The morning marine layer leaves those uninsulated cavities damp and cold year-round, and the inside face of exterior walls starts peeling paint, a recurring problem that keeps coming back until the cavity is sealed with foam.
- Attic heat building above 120°F in summer. Artesia’s coastal plain gets moderate daytime temperatures, but that roof deck still bakes. If an attic is sealed without correcting ventilation, the heat and moisture have nowhere to go and the deck starts collecting condensation.
- Irregular framing in unpermitted additions. Original 1950s and 60s wall cavities were built one way, but unpermitted room additions and garage conversions rarely match that framing pattern. Thin foam passes and cold spots survive unless the cavity is mapped before spraying.
- Old knob-and-tube-era wall cavities. Homes built in the 1950s sometimes still have legacy wiring paths running through wall cavities that were never insulated. Spraying around these requires care and a clear plan, not a blind pass with a gun.
On a converted-garage job near the 90701 tract blocks, our crew pulled back drywall and found bare studs with an old unsealed exterior penetration letting marine-layer damp bleed in, and the inside face of the exterior wall already peeling paint. We sealed the penetration and closed the cavity with Icynene spray foam to stop the condensation cycle, then verified attic ventilation before we left. The space now holds a stable temperature instead of feeling damp and cold every morning.

FAQs About Spray Foam Insulation in Artesia
Yes, in most Artesia homes that peeling paint is a symptom of a moisture cycle, not a paint failure. The wall cavity is cold on the inside because it lacks insulation, warm moist air from the room hits the cold surface, and condensation forms behind the paint. Spray foam breaks that cycle by air-sealing and insulating the cavity so the interior wall surface stays close to room temperature. The fix is permanent once the cavity is sealed, but you’ll still need to repaint the affected area after we close the wall. Call (877) 680-3557 and we’ll confirm what’s happening in your wall before you spend another dollar on paint.
Yes, we can insulate an unpermitted garage conversion. We’re insulation contractors, not building inspectors, and our job is to make the space comfortable and dry. We typically recommend open-cell Icynene foam for these cavities because it fills irregular framing well and doesn’t trap moisture against the studs. We will note any structural or electrical concerns we see so you can address them with the right trade, but our scope is the thermal envelope. Call (877) 680-3557 for a free estimate on the cavity measurements.
We use open-cell Icynene foam for most damp converted garage cavities in Artesia. Open-cell foam is vapor-permeable, which means it lets the wall assembly dry toward the interior instead of trapping moisture against the wood, a critical property when the marine layer is pushing damp air into the cavity every morning. Closed-cell Demilec works better where a true vapor barrier and structural reinforcement are needed, like rim joists and roof decks. We’ll tell you which one fits your specific wall condition after we open it up and see what’s actually behind the drywall.
It depends on where the foam goes. If we spray the attic floor and leave the attic itself unconditioned, the existing soffit and gable or ridge vents usually handle the heat load fine. If we spray the underside of the roof deck to make the attic conditioned space, we have to verify the roof assembly won’t trap summer heat and moisture against the deck, a real concern when Artesia attics sit above 120°F in August. We check ventilation as part of every attic quote, and we’ll tell you honestly if a ventilation correction needs to happen first or alongside the foam work.
We map the cavity first and verify what’s behind the wall before any foam goes in. In Artesia’s 1950s homes, legacy wiring paths sometimes run through stud bays that were never insulated, and spraying around energized legacy wiring without understanding the circuit layout is a bad idea. We flag any wiring concerns, work with you or your electrician to confirm the cavity is safe, and then we spray. The foam itself doesn’t damage wiring, but the cavity needs to be understood first. Call (877) 680-3557 if you’re unsure what’s in your walls, and we’ll help you figure out the next step.
