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.

Our Duct Repair & Sealing Services in West University Place
Duct Sealing with Mastic Sealant
In West University Place’s older homes - the surviving 1940s-1960s stock that hasn’t been torn down yet - the original sheet-metal duct seams were often sealed with fabric tape that dries and cracks after decades in a 130-150°F attic. We remove that failed tape and apply mastic sealant (a thick, brush-applied compound that remains flexible) to every joint and seam. A typical mastic sealing job in West University Place runs $450-$750 for a single-system home. The work is verified with a static pressure test before we leave.
Flex Duct Repair
Flex duct - the insulated, flexible tubing common in attic-mounted systems - is what we repair most often in West University Place. In new teardown-rebuilds, extensive flex duct runs are standard. In older homes, flex has often been added during past HVAC upgrades. The problem is the same: sagging, crushed, or disconnected flex dumps conditioned air into the attic. On a block off University Blvd where an original 1950s bungalow sits beside a freshly framed custom build, our tech ran a camera inspection on the return side and found three flex duct collars at the air handler knocked loose, with attic insulation and drywall dust pulled into the run. We re-seated and mastic-sealed every connection, re-wrapped the sagging flex with new insulation, and verified static pressure across the supply and return ducts afterward. The homeowner had been paying to cool the attic for months without knowing it. Flex duct repair in West University Place typically runs $180-$340 per run.
Metal Duct Repair
The original galvanized steel ducts in West U’s pre-1970 homes were built to last, but the fiberglass liner inside them wasn’t. When that liner deteriorates, it sheds fibers into the airflow and provides a porous surface for mold in Houston’s persistent humidity. We repair accessible metal duct sections, replace deteriorated liner where possible, and seal seams with mastic. For sections too far gone, we fabricate replacement metal duct to match. Metal duct repair in West University Place starts around $320 for accessible sections and ranges to $650+ for extensive liner replacement or custom fabrication.
Duct Insulation Replacement
Attic insulation on flex duct compresses over time, especially in West University Place’s extreme attic heat. Once the R-value drops, condensation forms on the duct exterior in summer, feeding mold growth and reducing system efficiency. We strip damaged insulation and install new wrap with proper vapor barrier, sealed at every seam. Duct insulation work in West University Place typically runs $280-$520 depending on linear footage.

Common Duct Repair & Sealing Problems We See in West University Place Homes
- Adjacent teardown damage: In West University Place, where teardown-rebuilds happen lot-by-lot, the construction foot traffic from an adjacent new build routinely dislodges the attic flex duct connections in the surviving original 1940s-1960s home next door - so that older house starts dumping conditioned air and duct debris straight into a 130-150°F attic instead of through its registers.
- New-build handover debris: Builder crews leave drywall dust, sawdust, and construction debris sitting in the supply and return ducts, and the first-time owner runs the system for months before anyone thinks to clean it - by then the debris has been pushed through every register and coated the air handler and blower motor.
- Deteriorated fiberglass liner in original ducts: A West U homeowner renovates around the old fiberglass-lined sheet-metal ducts, but the deteriorating liner keeps shedding fibers and trapping allergens, so the system never actually gets clean no matter how many times it’s serviced.
- Humidity-driven mold in sagging flex: Houston’s 75% average relative humidity and 9-10 month cooling season means any flex duct that sags and pools condensation becomes a mold colony within a season - a problem we find more often in West University Place’s older homes than in newer suburbs with better attic ventilation design.

FAQs - Duct Repair & Sealing in West University Place
Builder crews almost never clean ducts before handover. Drywall dust, sawdust, and construction debris sit in the supply and return ducts through final inspections, and the first-time owner runs the system for months before anyone thinks to check - by then the debris has been pushed through every register and coated the air handler and blower motor. We recommend a post-construction duct inspection before move-in, or within the first 90 days of occupancy. Call (346) 248-1474 for an exact quote - estimates are free.
The builder should have sealed all ducts during construction to prevent debris entry, performed a post-construction cleaning of all supply and return runs, and verified static pressure and airflow balance before certificate of occupancy. Most do not. Our Duct Repair & Sealing team documents what we find with before-and-after photos, so you have a record if warranty issues arise later. Call (346) 248-1474 for an exact quote - estimates are free.
Yes. Heavy construction foot traffic in adjacent attics routinely dislodges flex duct collars and knocks loose mastic seals in the surviving older home. We’ve found this exact scenario on multiple West University Place blocks where original homes sit next to active build sites. If your energy bills have risen without explanation or rooms have become harder to cool, a camera inspection of the attic duct connections is warranted. Call (346) 248-1474 for an exact quote - estimates are free.
We use negative-pressure extraction - each duct run is sealed to a vacuum collection unit that maintains suction while rotary brushes or compressed air tools dislodge debris. The debris is captured at the source, not pushed into the living space. In West University Place’s high-humidity environment, we also verify that no moisture has pooled in low points of the duct system before sealing, since trapped water plus Houston’s heat equals mold. Call (346) 248-1474 for an exact quote - estimates are free.
Sealing matters more in older homes. The original sheet-metal ducts in West U’s 1940s-1960s stock were joined with tape that fails after decades in attic heat. Unsealed leaks pull hot, humid attic air into the system, overload the AC, and reintroduce moisture that cleaning alone cannot fix. We clean first, then seal with mastic, then verify with a static pressure test - in that order. A typical mastic sealing job in West University Place runs $450-$750. Call (346) 248-1474 for an exact quote - estimates are free.
