Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterFast, Reliable Duct Sealing Across Fulshear
We dispatch our Duct Sealing crews to Fulshear from our Houston scheduling office, and we know the area well enough to find Cross Creek Ranch, Fulshear Lakes, or the newer sections along FM 1093 without GPS coaching. Most Fulshear appointments book within a few days, not weeks, because we keep dedicated crews west of the metro. If your home was built since 2010 and your rooms won’t hold temperature, your ducts are probably leaking conditioned air into the attic before it ever reaches the vents. Call (361) 326-5060 and we’ll put a written price in front of you before any work starts.

Duct Repair in Fulshear
Duct Repair in Fulshear usually means fixing what the builder left unfinished: crushed flex runs, disconnected trunk takeoffs, and return plenums that were never properly sealed before drywall went up. We see this in new construction from Cross Creek Ranch to the townhomes near FM 359, where crews work fast and HVAC is often the last trade rushed through the punch list. A typical duct repair in Fulshear runs $280 – $520 depending on how many runs need attention and whether we need to replace damaged flex duct sections entirely.
Crushed or Kinked Flex Runs
Construction traffic in Fulshear’s active building zones leaves flex duct flattened under insulation or pinched against framing. We replace the damaged section with properly sized flex, support it with strapping so it won’t sag, and seal every connection with mastic, not tape that will dry out in your attic heat.
Disconnected Plenum Joints
The plenum – the metal box that connects your air handler to the duct trunk – often leaks at its seams in Fulshear homes because builders rely on foil tape instead of sealed mastic joints. We disassemble, clean, reseal with mastic, and pressure-test before we leave.
Air Duct Sealing in Fulshear
Air Duct Sealing in Fulshear targets the gaps and leaks that let conditioned air escape into your attic and pull hot, dusty attic air back into your system. In a community where most housing is 2010s-and-newer, the problem isn’t age – it’s builder-grade installation where flex duct connections at the plenum and trunk takeoffs were left unsealed. A typical whole-system air duct sealing in Fulshear runs $450 – $890 for an average two-story home, with smaller townhomes or duplexes toward the lower end and larger homes with multiple zones toward the higher.
Mastic Sealing at All Joints
We brush mastic, a thick rubberized sealant, onto every joint and seam in your accessible ductwork. Unlike foil tape, mastic stays flexible through Fulshear’s attic temperature swings and won’t peel off when humidity spikes during hurricane season.
Pressure Testing After Sealing
After sealing, we run a static pressure test to confirm the system holds pressure and that your air handler isn’t working against itself. In Fulshear’s new homes, we often find static pressure drops of 20 – 30 percent after proper sealing, which means your system runs less, lasts longer, and actually cools the rooms it was sized for.
Trusted Brands We Service in Fulshear
Our crews carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, plus filtration and sealing products from Honeywell, Aprilaire, and Guardsman. We stock common flex duct sizes, mastic, and collar fittings used in Fulshear’s new construction so we’re not waiting on parts while your attic sits open. For sealing jobs, we specify Aprilaire media air cleaners and Guardsman filtration upgrades when the original builder-grade filter is undersized for the system, which we see often in Fulshear’s two-story plans with single returns.
Common Duct Sealing Problems We See in Fulshear Homes
- Builder-installed flex duct left unsealed at the plenum. In Fulshear’s master-planned communities, we regularly find flex duct connections that were never mastic-sealed at the plenum or trunk takeoffs. Conditioned air leaks straight into 140-degree attics, and your system runs overtime trying to hold the thermostat setpoint.
- Undersized returns paired with oversized air handlers. Builders in fast-growing Fulshear subdivisions often spec a single return for a two-story home, creating negative pressure that pulls drywall dust and insulation fibers past the filter and into your supply ducts. Sealing the return path properly – and sometimes adding a return – fixes the pressure imbalance.
- Flex duct crushed or kinked during construction. With so many homes built quickly in Fulshear, flex runs get stepped on, buried in blown insulation, or bent around framing without proper support. The turbulence erodes seals and lets humid Gulf Coast air condense inside, feeding mold and mildew that you’ll smell before you see.
- Construction debris left in the system at handover. We pulled a return plenum in Cross Creek Ranch that still had drywall dust caked on the inside and a soda bottle wedged against the blower motor – the builder never capped or cleaned the flex runs before handover. After sealing the leaking plenum joints and reconnecting the undersized return, our tech used a camera inspection to confirm no debris remained, and the homeowner’s “new house smell” disappeared within a day. The system’s static pressure dropped enough that the air handler stopped short-cycling.
Pricing for Duct Sealing in Fulshear, TX
Whole-system duct sealing in Fulshear typically runs $450 – $890 for an average single-family home, with most two-story homes in Cross Creek Ranch or Fulshear Lakes falling in the $600 – $750 range. Smaller townhomes and duplexes start around $350 – $500. Duct repair for specific damaged runs runs $280 – $520.

FAQs About Duct Sealing in Fulshear
Yes, probably. Fulshear’s newest homes often need duct sealing sooner than owners expect because builder-grade flex duct and construction debris, not age, are the real culprits. We’ve sealed ducts in homes less than a year old where the plenum joints were never mastic-sealed and the flex runs were full of drywall dust. Call (361) 326-5060 for an exact quote – estimates are free.
Sealed ducts stop pulling 140-degree, humid attic air into your system, which reduces the moisture load your air conditioner must remove. In Fulshear’s climate, where attics stay brutally hot and damp most of the year, every leak in your return path is an invitation for mold growth and a reason your system can’t keep up in July. Call (361) 326-5060 for an exact quote – estimates are free.
The builder should have capped all duct openings during construction, cleaned the system before startup, mastic-sealed every plenum and trunk connection, and verified static pressure with a manometer. In Fulshear’s fast-build environment, few do all four. We often find the first three skipped entirely. Call (361) 326-5060 for an exact quote – estimates are free.
Often yes, but not always by itself. Uneven temperatures in Fulshear’s two-story homes usually come from leaky supply ducts dumping air into the attic before it reaches the second floor, plus undersized returns that can’t move enough air. Sealing fixes the leaks; sometimes we also need to add a return or balance dampers. We diagnose both before we quote. Call (361) 326-5060 for an exact quote – estimates are free.
We work in the attic and at the air handler, not through your living space. Our crews wear boot covers, lay protection at the attic access, and vacuum the work area before we leave. The Garrison Standard requires leaving the site clean – it’s part of the job, not an extra. Call (361) 326-5060 for an exact quote – estimates are free.
