Serving Highland, CA and surrounding areas. (909) 737-6056
Hidden gaps in your attic and walls let hot outside air in and cool inside air out all summer long. Air sealing closes those pathways so your AC stops fighting a losing battle and your home stays comfortable.
Air sealing services in Highland, CA means finding and closing the small gaps, cracks, and openings in your home where outside air sneaks in and conditioned air leaks out - most jobs on a single-family home are completed in one to two days without any major disruption. In the San Bernardino Valley, where summer heat tops 100 degrees and wildfire smoke rolls through the area most summers, those gaps matter more than homeowners typically realize until they look at their electric bill or smell smoke inside with the windows closed.
The leaks are usually hidden - around recessed lights in the ceiling, where walls meet the attic floor, and where pipes and wires pass through surfaces. Homes built before 1990 were constructed at a time when air sealing was not standard practice, and most Highland homes from that era have never been properly sealed. Many homeowners combine air sealing with attic air sealing to address the area where most leakage occurs first, then move to the rest of the home.
California and Southern California Edison both offer programs that may offset the cost of qualifying air sealing work. Ask us about current eligibility before your project starts.
If certain rooms in your Highland home feel noticeably warmer even when the AC is running, hot attic air is likely finding its way into your living space through gaps in the ceiling. In a climate where summer temperatures regularly exceed 100 degrees, even small openings in the attic floor can push significant heat into the rooms below. Air sealing those penetrations is usually the fix.
If your home smells like smoke during a nearby fire or fills with fine dust even when the windows are closed, outside air is getting in somewhere it should not. Highland and the surrounding Inland Empire see wildfire smoke events most summers and falls, and homes with unsealed attic penetrations or gaps around recessed lights are especially vulnerable to that infiltration.
If your Southern California Edison bill has been creeping up year over year without any change in your habits, air leakage is a likely contributor. An AC working against a leaky home has to run longer and harder to maintain the same temperature, and that shows up directly on your bill. A noticeable jump in summer cooling costs is one of the clearest signals that air sealing deserves a closer look.
Hold your hand near an electrical outlet or light switch on an exterior wall - if you feel slight air movement, that is outside air coming in through the wall cavity. The same test works near recessed ceiling lights, which are one of the most common leakage points in older homes. These drafts are easy to miss because they are small, but they add up across dozens of openings throughout the house.
We assess your home for air leakage using a blower door test, which depressurizes the house and makes it easy to detect exactly where air is moving in and out. That measurement gives you a real number before the work starts - and we test again after so you can see the improvement, not just take our word for it. The sealing work covers attic penetrations, recessed light fixtures, gaps around plumbing and electrical, and any other openings our assessment identifies. For homes where the attic is the biggest problem, we also offer focused attic air sealing as a standalone service if that is where you want to start.
Air sealing works best when paired with insulation. Sealing closes the gaps where air moves freely, and insulation slows the heat that travels through solid materials - the two address different parts of the same problem. We can handle both at once, which is more efficient and more cost-effective than two separate visits. We also offer basement insulation for homeowners who want to address heat and moisture coming from below after the attic and walls are sealed.
Comprehensive assessment and sealing of all major leakage points - attic floor, walls, recessed lights, and penetrations.
Focused on the attic floor, which is where most leakage occurs in Highland homes built before 1990.
Before-and-after measurement of your home's air tightness so you have documentation of exactly what improved.
Sealing and insulation scheduled together for homeowners who want both problems addressed in a single visit.
Highland sits at the edge of the San Bernardino Valley, where summer temperatures regularly climb above 100 degrees and sometimes push past 110. Every gap in your home's envelope makes your air conditioner work harder and run longer - and in a climate where cooling season stretches from May through October, that adds up fast. A significant share of Highland's single-family homes were built in the 1960s through the 1980s, when air sealing was simply not part of how homes were constructed. Those homes were built to breathe, which sounded fine at the time but means decades of unchecked air movement through attic floors, wall cavities, and every pipe or wire penetration. The U.S. Department of Energy estimates homeowners can save up to 20 percent on heating and cooling costs by air sealing and adding insulation together - in Highland's climate, that is real money every month.
Wildfire smoke adds a second reason this work matters here. The Inland Empire, including Highland, experiences periods of poor outdoor air quality from fires in the San Bernardino Mountains and across Southern California. Homes with unsealed attic penetrations pull that smoky air in through gaps that would otherwise be invisible. Sealing those pathways keeps smoke and fine particulates outside where they belong - especially important for households with children or anyone with asthma. Homeowners in Colton and San Bernardino face the same conditions and see the same benefits from this work.
We respond within 1 business day. We will ask about your home's age, what has been bothering you - high bills, smoky smell during fire season, hot rooms - and whether you have had any energy work done before. No cost to reach out, no obligation.
We walk your home and inspect the areas most likely to have air leakage - the attic, recessed lights, plumbing and electrical penetrations. Many assessments include a blower door test that measures how much air is currently moving through your home. This step gives us the information needed to give you an accurate quote.
We walk you through exactly what we found and what we recommend sealing first. The estimate is written and itemized - no verbal quotes, no surprises. You should feel comfortable asking questions about anything before signing.
We work through the identified problem areas, applying the right material - spray foam, caulk, or weatherstripping - to each gap. When the work is done, we re-test with the blower door so you can see the improvement in real numbers, then walk you through what was done.
Free estimate, no pressure. We respond within 1 business day.
(909) 737-6056We have been working on homes in Highland and throughout the Inland Empire since 2016. We know the era of construction, the typical leakage points in local housing stock, and the seasonal conditions - summer heat and Santa Ana winds - that make air sealing a priority here, not just an upgrade.
We test your home's air tightness before we start and again when we finish. You get real numbers showing what improved - not just an assurance that the job was done right. That documentation is yours to keep, and it matters if you ever sell or refinance.
Highland is in Southern California Edison's service territory, and qualifying air sealing work may be eligible for rebates through SCE's energy efficiency programs. We know the current requirements and can walk you through the paperwork before the job starts so you do not miss a deadline or a program cutoff.
We hold a valid California Contractors State License Board license, which you can verify before hiring us. The Building Performance Institute sets standards for home energy professionals that guide how we assess and seal homes - so we are working to a verified methodology, not guesswork.
When you call us for air sealing in Highland, you get a crew that measures before and after, knows how to access rebates that reduce your cost, and backs the work with documentation you can keep. That combination is what separates a job that actually delivers from one that looks complete but leaves money on the table.
After sealing air leaks above, address heat and moisture entering through the basement or slab.
