Your insulation can only do so much if gaps in your walls, attic, and floors are letting hot outside air pour in. Air sealing closes those leaks so your AC works with your home, not against it.
Air sealing services in Del Rio means finding and closing the gaps, cracks, and openings in your home where outside air sneaks in and conditioned air escapes, most jobs take one to two days and can be done while you stay in your home.
These gaps are often invisible - hidden in attic floors, around pipes, behind electrical outlets, and along the edges where walls meet ceilings. In Del Rio's climate, where the cooling season runs from April through October, every one of those gaps is working against your air conditioner every single day. Closing them is one of the most cost-effective improvements you can make to a home here.
Air sealing works best as a companion to insulation. When you pair it with basement insulation or attic work, you get the full benefit of both - insulation slows heat transfer while sealing stops air movement. Together, they solve the problem; separately, each leaves something on the table.
If your cooling costs jump sharply between May and September even when you keep the thermostat steady, hot outside air is likely getting in faster than your AC can handle it. Del Rio's long, intense cooling season amplifies this effect, and a home with significant air leaks will show it clearly on your utility statements. Compare your bills month to month and look for a pattern that does not match your actual usage.
Del Rio's desert surroundings mean fine dust and grit are constantly present in the outdoor air. If you find a thin layer of dust reappearing on shelves or furniture within a day or two of cleaning, that dust is entering through gaps in your home's envelope. This is especially common near electrical outlets on exterior walls, around window frames, and along baseboards.
When one bedroom or corner of the house is always harder to cool than the rest, that area likely has more air leaks than the others. Hot outside air is entering faster than the AC can offset it in that space. This is common in older Del Rio homes where the original construction included no air sealing at all.
Hold your hand near an electrical outlet or light switch on a wall that faces outside. If you feel a faint flow of air on a hot afternoon, that outlet is connected to a gap running straight through the wall. This is one of the easiest leaks to detect yourself and one of the most common in homes built before the 1990s.
Our air sealing work starts with finding the leaks, not guessing. In most cases we run a blower door test - a temporary fan in your front door that pulls air out of the house and makes gaps easy to locate. From there we seal each problem area with the right material: spray foam for gaps around pipes and framing, caulk for smaller cracks along trim and baseboards, and weatherstripping for moving parts like doors. Each material is matched to the specific location so the fix holds.
We also offer dedicated attic air sealing, which addresses the attic floor - the single biggest source of air loss in most homes. Because attic sealing involves moving insulation aside to reach the gaps underneath, it is most efficient when scheduled as part of a broader insulation project. The U.S. Department of Energy and ENERGY STAR both identify air sealing as one of the highest-return home energy improvements available.
Best suited for homeowners who want a comprehensive fix - we address the attic floor, all penetrations, and the building envelope in a single project.
Focused on the attic floor plane, where most air loss in a typical home occurs - ideal when scheduled alongside attic insulation work.
The most cost-effective option - combining air sealing and insulation in one visit saves money and delivers better results than scheduling them separately.
For homeowners who want a clear picture of where their home is leaking before committing to any work - a diagnostic first step with no obligation.
Del Rio sits in the Chihuahuan Desert borderlands, where summer temperatures regularly exceed 100 degrees and the cooling season stretches from April through October. That means your air conditioner is running hard against hot outside air for more than half the year, and every gap in your home's envelope is making that job harder. Air sealing here is not a comfort upgrade - it is a practical response to one of the longest and most intense cooling seasons in Texas. A significant share of Del Rio's residential neighborhoods were built from the 1950s through the 1980s, a period when air sealing was not a standard part of construction. Those same gaps are working against your cooling system every day. Homeowners near Laughlin AFB and in the older neighborhoods near downtown see this problem regularly.
Del Rio's monsoon season - roughly June through September - also brings bursts of warm, humid air that can push through unsealed gaps and into wall cavities where moisture can accumulate unseen. Proper air sealing reduces the amount of that humid air getting in, protecting your home's structure as well as your energy bills. Homeowners in Comstock and across the surrounding communities deal with the same Chihuahuan Desert conditions, and we serve the full region. Federal tax credits may also be available for qualifying air sealing work - ask us about current IRS energy efficiency credits when you call.
We ask about your home's age, size, and what has been bothering you - high bills, hot rooms, dust, drafts. You do not need to know any technical details. We reply within one business day and schedule an assessment visit.
We walk through your home and run a blower door test - a large fan in your front door that pulls air out and makes leaks detectable. The visit takes about an hour and we show you what we find before recommending any work.
You receive a written breakdown of the specific areas to be addressed and the total cost. If a permit is required in Del Rio, we handle the filing. Take your time to review - we will not pressure you to decide on the spot.
The crew seals gaps throughout the attic, around penetrations, and along your home's framing. Once complete, we run a second blower door test to show you the measurable before-and-after improvement. You receive documentation for your records.
Free estimate, no obligation. We reply within one business day and explain exactly where your home is leaking and what it will cost to fix it.
(830) 507-8640We measure air leakage before we start and again after we finish, giving you a concrete number that shows exactly how much improvement was made. You are not taking our word for it - you have documented proof. That documentation also supports federal tax credit filings.
Many of the homes we seal in Del Rio were built in the 1950s through 1980s - before air sealing was a standard practice. We know where to look in these homes and what to expect, which means we find more leaks and fix them correctly the first time.
We match the sealing material to the specific location - spray foam for larger gaps around pipes and framing, caulk for finer cracks, weatherstripping for moving parts. Using the wrong material in the wrong spot means the fix fails. We do not use one product everywhere.
We live and work in Del Rio. When you call us back with a question six months after the job, you are calling neighbors - not a call center. That local accountability shapes how we approach every project from the start. Texas licensing through the TDLR backs our work.
Air sealing is permanent work that pays for itself every cooling season. The combination of measurable results, correct materials, and local knowledge is why Del Rio homeowners keep calling us back.
