Heat pouring through your walls makes your AC run constantly and your bills climb every summer. Wall insulation slows that heat at the source, so your home stays cooler and every room is actually livable.

Wall insulation in Highland, CA slows the movement of heat through your exterior walls, keeping your home cooler in summer without your AC running nonstop - most jobs on a finished single-story home are completed in one day. In the San Bernardino Valley, where summer temperatures regularly exceed 100 degrees, that difference shows up directly on your Southern California Edison bill and in how comfortable every room feels.
A large share of Highland homes were built between the 1970s and 1990s, when wall insulation standards were far lower than they are today. Many of those homes have little or no insulation in their wall cavities - and owners have been paying for that gap on every summer electric bill since. Wall insulation can be installed through small drilled holes in finished walls without tearing out drywall, so the disruption is far less than most homeowners expect. Many homeowners also add air sealing services at the same time to close the gaps that let hot air bypass the insulation entirely.
Southern California Edison offers rebates for qualifying insulation upgrades in Highland. Ask us about current programs before work begins so you can capture that savings.
If your Southern California Edison bill climbs dramatically from June through September despite no changes to your habits, your walls may be letting heat pour in faster than your AC can handle. In Highland's climate, a well-insulated home holds its temperature much more efficiently - a runaway summer bill is one of the clearest signs that your walls are underperforming.
Walk through your home on a 100-degree afternoon and pay attention to which rooms feel uncomfortable even with the AC running. Rooms that face west or south and feel significantly warmer than the rest of the house often have walls with little or no insulation. That uneven temperature is a reliable indicator that heat is moving through the wall rather than being slowed down.
Hold your hand near an electrical outlet or light switch on an exterior wall during a windy day - especially during Santa Ana season. If you feel air movement, that is a sign your wall cavity has gaps letting outside air in. This is both a comfort problem and an energy problem, and it is something insulation and air sealing together can fix.
Many homes in Highland's established neighborhoods were built with minimal wall insulation by today's standards. If you have lived in your home for years and cannot recall any insulation work being done, there is a reasonable chance your walls are underperforming. A quick check by a contractor - often free - can tell you exactly what is there and what is missing.
We install wall insulation in finished and open walls throughout Highland using blown-in and spray foam methods. For most homes with drywall already in place, blown-in is the go-to choice - we drill small holes, fill each wall cavity completely, then patch and smooth every hole before we leave. There is no major disruption and no drywall replacement needed. For homes undergoing a remodel where walls are open, we can apply spray foam insulation directly to the open cavity, which also seals any air gaps around wiring and plumbing in the same step.
We strongly recommend pairing wall insulation with air sealing services because insulation slows heat transfer while air sealing closes the gaps where hot air moves freely regardless of how much insulation is present. Doing both at once delivers the best outcome and is often more cost-effective than scheduling separate visits. We walk through your home and recommend only what your specific walls actually need.
Best for finished walls - installed through small drilled holes, no drywall removal required, and patched clean on completion.
Ideal during a remodel when walls are open - fills cavities, seals air gaps, and bonds directly to the framing.
For homes where drafts are the primary complaint - seals around outlets, pipes, and framing gaps before insulation goes in.
For homeowners who want to know exactly where heat is entering before deciding which walls to prioritize.
Highland sits in the San Bernardino Valley, where summer heat regularly climbs above 100 degrees and heat waves can push past 110. That sustained heat puts enormous pressure on walls that are not well insulated - your air conditioner runs almost constantly trying to fight heat that is radiating straight through the wall. A significant share of Highland's neighborhoods were built in the 1950s through 1980s, when insulation standards were far lower than they are today. Many of those homes were built with little or no wall insulation at all, and the material that was installed in others has degraded over decades. California's energy code sets minimum standards for any permitted renovation, so if your project requires a permit, a licensed contractor will handle that process for you through San Bernardino County Building and Safety. You can verify any contractor's license on the California Contractors State License Board website before hiring.
Santa Ana wind events in fall and winter add a second reason to take wall insulation seriously here. When dry, fast winds push through the Inland Empire, they force outside air through every gap in your home's exterior - and you feel that directly near outlets and light switches on exterior walls. Homeowners in Redlands and Loma Linda face the same seasonal conditions, and properly insulated walls paired with air sealing address both the thermal problem and the infiltration problem that Santa Ana season exposes.
We respond within 1 business day. We will ask a few basic questions - your home's age, approximate size, and what has been bothering you most. There is no cost to reach out and no obligation to move forward.
A member of our team walks your home, checks what is currently in your walls - sometimes with a thermal camera or a small test hole - and looks at your attic since heat loss there often compounds the wall problem. You receive a written estimate that explains exactly what was found and what it will cost.
If your project requires a permit through San Bernardino County, we handle pulling it. This typically adds a few days before work begins. Once we have the permit, you pick your installation date and we tell you exactly how to prepare.
The crew drills small holes, fills each wall cavity completely, and patches every hole smooth before leaving. Most single-story Highland homes are done in one day. You stay home - the work is noisy but not hazardous - and your walls look the same as when we started, just far better insulated.
Free estimate, no pressure. We answer within 1 business day.
(909) 737-6056We have been working on homes in Highland and the surrounding Inland Empire since 2016. We know the housing stock, the local climate, and the kinds of problems that show up in homes built during the valley's growth years. That familiarity means fewer surprises on the job.
We hold a valid California Contractors State License Board license. You can verify our license number before you hire us - the CSLB makes that fast and free. A licensed contractor is also the only way to get permitted insulation work inspected and approved under California's energy standards.
Highland is served by Southern California Edison, and qualifying insulation upgrades may be eligible for SCE rebates. We are familiar with the program requirements and can walk you through what paperwork to submit before the job starts - so you do not miss out on savings after the work is done.
Every project starts with a written quote that specifies the scope, the materials, and the price. No verbal estimates, no surprise charges. The estimate is based on what we actually find in your home - not a flat rate applied without looking. The North American Insulation Manufacturers Association sets installation guidelines we follow on every job.
Every one of those proof points matters on a project that will be in your walls for decades. When you hire Highland Insulation, you get a crew that knows Highland homes, follows California code, and backs every job with a written estimate - no guessing required.
Seal the gaps around outlets, recessed lights, and wall penetrations so your new insulation performs at its best.
