We respond within 1 business day and schedule a free on-site estimate at your convenience. There is no obligation and no pressure to commit on the first call.
One of our team members comes to your home, inspects your attic, walls, or crawl space, and measures what is already there. We check for any moisture, pest damage, or air leaks that need attention first. Then we give you a written estimate that explains what we recommend, why, and what the total cost will be - with no hidden line items added later.
Our crew arrives on the agreed day, protects your home, and completes the job to the scope you approved. Before we leave, we walk you through what was done so you can see the result yourself. If a permit is required in Calexico, we handle that process on your behalf. You should notice a real difference in comfort and energy use within the first hot days after installation.
We carry full liability insurance and are properly licensed to perform insulation work in California. Every job - big or small - is covered. You are never exposed to risk from an uninsured crew on your property.
We come to your home, inspect the space, and give you a written estimate at no charge. You are under no obligation to book. Most homeowners find the in-person assessment answers questions they did not even know they had before we arrived.
We have been working in the Imperial Valley since 2018. We know this climate, the older housing stock in Calexico, and what the desert heat does to homes that were built before modern insulation standards existed. That local knowledge shows up in every assessment we do.
Every job comes with a written estimate before work starts and a completion record when the job is done. The price you agree to is the price you pay. We document the type of material, the coverage area, and the depth achieved - so you have proof of what was done.

"The crew finished our attic insulation in one day and cleaned up completely before they left. We noticed the difference that same week - our back bedrooms stopped feeling like a sauna by late afternoon, even with the AC set to the same temperature."
Maria R., El Centro - Attic insulation
"I had spray foam done in my crawl space and walls last spring. My IID bill in July came in noticeably lower than the same month last year. The estimator was straightforward, gave me a written quote on the spot, and the job came in exactly at that number."
Carlos V., Calexico - Spray foam insulation
"We had old, compressed insulation in our attic that had clearly been there since the house was built in the 70s. They removed it all, air-sealed the gaps, and installed new blown-in material in a single visit. The estimate matched the final invoice exactly."
Rosa T., Brawley - Insulation removal and blown-in insulation
We respond within 1 business day - no waiting a week to hear back. This estimate is completely free and comes with no obligation to book. After you submit, someone from our office will call you to schedule a free on-site visit so we can see your home and give you an accurate written quote.

In most cases, heat is entering faster than your AC can remove it - usually through a poorly insulated attic. Attic temperatures in Calexico can reach 150 degrees in summer, and without adequate insulation, that heat radiates straight into your living space. Adding insulation to the attic floor is almost always the highest-impact first step. The U.S. Department of Energy estimates that proper insulation and air sealing can cut cooling costs by up to 15 percent.
Almost certainly, yes. Homes built in Calexico before the 1980s were constructed under energy standards that would be considered inadequate today - especially for a Climate Zone 15 desert location. If you can see the wooden joists through your attic insulation, you do not have enough. A contractor can measure what is there and tell you exactly how far short you are in about 30 minutes.
Yes - and this is a benefit specific to the Imperial Valley. The same gaps that let heat in also let fine desert dust through. Spray foam and air sealing close off those pathways, so the air coming into your home travels through your filter rather than through cracks around outlets, attic penetrations, and wall joints. Many homeowners notice less dust on surfaces within a few weeks of installation.
The Imperial Irrigation District has historically offered energy efficiency rebates for residential insulation upgrades. Rebate availability and amounts can change, so check with IID before your project starts - some programs require pre-approval before installation. Your contractor should be familiar with the current programs and can help you navigate the process.
Always. Insulation slows heat, but air sealing stops drafts - and you need both working together to see real results. A home can have thick insulation and still feel hot if conditioned air is leaking out through gaps around electrical outlets, plumbing penetrations, and attic hatches. Many contractors handle both in a single visit, and combining them gives you noticeably better comfort than either step alone.
It depends on the scope. Routine attic top-ups often do not require a permit, but projects that are part of a renovation or that affect your home's energy performance rating typically do. California requires that permitted insulation work in Calexico meet the state's energy code for Climate Zone 15. A reputable contractor handles the permit process on your behalf and schedules the required inspection.

If your existing insulation is dry, undamaged, and not compressed by pest activity, adding new material on top is often fine. But if there is any moisture damage, mold, or rodent contamination, removal and replacement is the right call. A contractor can tell you which situation you have in about 15 minutes with a flashlight.
The most direct test is whether your home reaches and holds a comfortable temperature without the AC running constantly. If your home has adequate insulation, your AC should cycle off periodically - not run all day. If it runs nonstop on a 105 degree afternoon, heat is getting in faster than your system can remove it. ENERGY STAR has a useful guide to identifying insulation gaps in your home.
Insulation slows the movement of heat through solid surfaces. Air sealing stops air from physically moving through gaps and cracks. Both are necessary because a gap in your ceiling lets hot outside air straight into your living space, bypassing even thick insulation entirely. Most professional insulation jobs should include both steps.

Calexico sits directly on the US-Mexico border in the Imperial Valley, where summer temperatures regularly top 110 degrees and air conditioning runs almost nonstop from late spring through September. The city covers about 9 square miles and has roughly 40,000 residents, with most of the housing stock made up of older single-family homes built between the 1950s and 1980s. The National Weather Service tracks the extreme heat conditions that make Calexico one of the hottest communities in the United States during summer months.
Most homes in Calexico were built long before California's current energy codes took effect, and many have little to no original insulation in the walls or only a thin layer in the attic. Neighborhoods near the Calexico Port of Entry and along First Street in downtown Calexico contain some of the oldest housing in the city, where insulation upgrades have the most dramatic impact on comfort and cooling costs. The city's stucco exteriors and flat or low-slope roofs are common throughout these neighborhoods, both of which require specific insulation approaches to perform well in the desert heat.
Calexico Insulation has been working in Calexico since 2018, and our team knows the housing stock, the local climate, and what it takes to make an older Imperial Valley home comfortable year-round. Whether your home is near Calexico High School or on the north end of town close to the Imperial Valley's agricultural border communities, we serve all of Calexico and the surrounding region. Call us and we will tell you exactly what your home needs.
