Every gap and crack in your home's envelope lets cooled air escape and 100-degree heat pour in. We find every leak and seal it so your AC does less work and your home holds comfort all summer.
Air sealing in Merced closes the gaps, cracks, and penetrations in your home's envelope where outside air exchanges with conditioned air — most whole-home jobs take one to two days and deliver measurable reductions in energy use.
Insulation slows heat from moving through materials. Air sealing stops air from moving through gaps entirely. Both are needed, but many Merced homeowners have insulation and still lose a significant amount of conditioned air because the leaks were never addressed. The attic is almost always the biggest culprit: gaps around ceiling fixtures, wall top plates, and plumbing chases create a direct path for hot attic air to pour into your living space.
Air sealing delivers the best results when paired with insulation. Many homeowners combine it with attic air sealing and basement insulation in the same project to address the top and bottom of the home's envelope at once.
If your PG&E bill jumps dramatically from May through September even though your habits have not changed, air leaks are a likely cause. In Merced's triple-digit summer heat, an air conditioner fighting leaky walls and attic gaps runs almost constantly. That sustained run time is what drives the high bill.
When the San Joaquin Valley's air quality climbs, you should be able to close your windows and feel protected inside. If you notice a haze, smell smoke, or find fine dust on surfaces even with windows shut, outdoor air is getting in through gaps somewhere. That is both an air quality problem and an energy problem in the same house.
If one bedroom is noticeably warmer in summer or colder in winter than the rest of your home, that room likely has more air leaks than others. Common culprits include gaps around windows, outlets on exterior walls, or an attic hatch that does not seal properly. You can feel this pattern just by walking through your home.
Hold your hand near an electrical outlet on an outside wall on a hot summer afternoon. If you feel warm air coming through, that outlet is connected to the outside through gaps in the wall. This is one of the easiest air leak tests a homeowner can do without any equipment, and it is a clear sign air sealing is needed.
We provide whole-home air sealing using foam, caulk, and weatherstripping depending on where each leak is located and how large the opening is. The process starts with a blower door test that measures exactly how leaky your home is before we touch anything. That gives us a baseline number and helps us prioritize where to work first so you get the most impact for your investment.
Attic air sealing is the most common focus and often delivers the largest energy savings in Merced homes. The attic floor is full of penetrations, from ceiling fixtures and recessed lights to wall top plates and plumbing chases, that create a direct exchange between your living space and the hot attic above. We seal each one systematically. For homeowners who also want to address their crawl space or basement, combining that work with basement insulation is the most efficient approach.
When air sealing is combined with insulation, the two projects share a single mobilization and the results are better than either delivers alone. We frequently pair whole-home sealing with attic air sealing and wall insulation in the same visit, which reduces overall cost and disruption. Ask during the assessment and we will show you what combination makes the most sense for your home.
Best for homeowners who want to address every leak source at once for maximum energy savings.
Best for homes where heat gain from above is the primary complaint and the attic has not been sealed before.
Best value for most Merced homes, since insulation and sealing work together and share a single mobilization cost.
Merced's extreme summer heat creates a stronger argument for air sealing than most places in California. Temperatures regularly exceed 100 degrees from June through September, and an air conditioner fighting a leaky home has to run almost continuously to keep up. Every gap and crack in the envelope is a place where your cooled air escapes and hot outside air rushes in to replace it. Sealing those openings is one of the most direct ways to reduce the load on your cooling system before summer arrives.
Air quality is a second reason air sealing matters here. The San Joaquin Valley, including Merced County, consistently ranks among the worst areas in California for particulate matter and ozone. During wildfire season and agricultural activity periods, the air outside can be genuinely unhealthy. Air leaks do not just cost energy — they let that outdoor air into your home through gaps you cannot see. The San Joaquin Valley Air Pollution Control District tracks daily air quality conditions, and a tightly sealed home is a real asset on those days.
We serve the entire Merced area and work in communities throughout the valley, including Fresno, Stockton, and Turlock. The same air quality and heat conditions that make air sealing valuable in Merced apply across the San Joaquin Valley, and we bring the same blower door testing process to every job.
We ask about your home's age, your energy bills, and whether any rooms feel uncomfortable. This call takes 10 to 15 minutes and helps us come prepared. We then schedule a free in-home assessment, not a phone quote.
A technician walks through your attic, checks plumbing and electrical penetrations, and runs a blower door test to measure exactly how leaky your home is. You receive a written estimate within one business day.
We seal gaps using foam, caulk, or weatherstripping depending on the location and size of each opening. Attic work is the most common focus and can take most of a day. Most homeowners stay home during the job.
We run a second blower door test after sealing to confirm the leaks are actually closed. You get a before-and-after number, photos of the work, and the documentation needed for any PG&E rebate applications.

(209) 308-1176Our California insulation contractor license is active and verifiable on the CSLB website. Every job is backed by liability insurance and workers' compensation so your home and our crew are protected.
We test your home before the work begins and again after it is done. You receive an actual airtightness number showing the improvement, not just our word for it. Very few contractors in the valley offer this level of verification.
We have worked on homes throughout Merced since 2022 and know where the common leak points are in the housing stock built here before modern energy codes. That knowledge makes the assessment faster and the results more thorough.
PG&E offers rebates for qualifying air sealing work in Merced. We provide all the documentation you need to apply, so you do not have to figure out the program requirements on your own. Many homeowners recover a meaningful portion of the project cost.
The combination of blower door testing, thorough attic sealing, and verified results separates a professional air sealing job from a contractor who just applies caulk in visible spots. We follow the standards published by the ENERGY STAR program and give you the documentation needed to access PG&E rebates and federal tax credits currently available for energy efficiency improvements.
