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.
Fast, Reliable Duct Repair & Sealing Across West University Place
Homes in West University Place run some of the most demanding duct systems in the Houston metro. Whether you’re in a brand-new 4,500 sq ft build off Bissonnet or a 1950s bungalow near Buffalo Speedway, duct leaks and construction debris force your HVAC to work harder than it should. Our Duct Repair & Sealing crews serve West University Place from our Houston coordination office, and we typically schedule within 48 hours. Call (346) 423-3631 for a written estimate before any work starts.
Why CleanRun Air Duct Cleaning Spring Is West University Place’s Preferred Duct Repair & Sealing Company
We’ve worked in West University Place since 2013, and the pattern is unmistakable: this 2.7-square-mile city has one of the highest teardown-and-rebuild rates in Greater Houston. That means our crews see two completely different duct problems on adjacent streets. One house is a six-year-old custom build with three separate HVAC systems and construction debris still in the trunk lines. Next door, a 1962 bungalow has original flex duct turning brittle in a 130°F attic. We don’t guess which one you have. We run a camera first.
Every West University Place job starts with a written price under Haven Standard Clause 1 - no exceptions, no “call for a quote.” Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and we publish our license number so you can verify before we arrive. The 365-Day Done Right Promise applies in writing on every West University Place home, not as a verbal assurance that disappears with the crew.
Our documented photo record is standard on every visit. You get before-and-after images of every duct run, delivered as part of the job record. In a market where most competitors hand you a receipt and a handshake, we hand you evidence.
Our Duct Repair & Sealing Services in West University Place

Duct Sealing with Mastic Sealant
West University Place’s Gulf Coast humidity - regularly above 85% near Brays Bayou - turns every pinhole leak into a moisture injection point. We seal supply and return joints with mastic sealant, a water-based compound that remains flexible after curing and bonds to galvanized steel, aluminum, and fiberglass duct board. Unlike foil tape, which degrades in Houston’s attic heat within two to three years, mastic maintains its seal through thousands of thermal cycles. In West U’s larger homes with multiple systems, we seal every joint in every network - not just the accessible ones - and photograph each location for the job record.

Flex Duct Repair
Surviving mid-century bungalows in West University Place often have flex duct installed in the 1980s or 1990s, routed through unconditioned attics where summer temperatures exceed 130°F. The insulation jacket degrades. The wire helix corrodes. Joints separate at the collar connections. We replace damaged flex duct runs with new R-8 insulated flex, secure collars with nylon draw bands and mastic, and support the run every four feet to prevent sagging that traps condensation. Last spring we were called to a newly built 4,200 sq ft home near the West University Place Recreation Center where the homeowner complained of dust blowing from the registers in three separate systems. Our tech ran a camera inspection through the supply and return ducts, found drywall dust and spray-foam overspray packed into the trunk lines and supply boots - construction debris never cleaned before move-in. We set up negative pressure with HEPA filtration, used agitation tools to free the debris, then sealed every leaking joint with mastic sealant and re-insulated the attic runs; the blower motor amp draw dropped and the dust stopped.

Metal Duct Repair
Post-teardown custom homes in West U sometimes use galvanized trunk lines with stamped branch takeoffs. We’ve found takeoffs partially detached from vibration during construction, and seams where the original installer skipped sealant. We reseat loose connections, apply mastic to all longitudinal and transverse joints, and reinforce with fiberglass mesh where pressure ratings demand it. Metal duct doesn’t forgive moisture the way flex does - rust propagates quickly once it starts - so we flag any corrosion we find and document it in the photo record.

Duct Insulation
In West University Place, duct insulation isn’t an efficiency upgrade. It’s humidity control. When cold supply air passes through an uninsulated or degraded jacket in a 130°F attic, the temperature differential creates condensation on the exterior surface. That water drips onto ceiling drywall, breeds mold in the insulation batts above, and eventually rusts metal components. We install or replace insulation on attic-routed ducts, paying particular attention to the plenum - the distribution box where conditioned air first enters the duct network - and to any exposed trunk lines that previous contractors left bare.

Every tool and filter is documented on the written scope you receive before work begins.
Common Duct Repair & Sealing Problems We See in West University Place Homes

- Construction debris in new custom homes. West U’s teardown-and-rebuild cycle means affluent buyers often occupy homes within weeks of final inspection. Drywall dust, spray-foam overspray, and blown-in insulation fragments pack into supply boots and trunk lines before the first cleaning. The HVAC runs, and that debris circulates through the registers.
- Heat-degraded flex duct in mid-century bungalows. Original or once-updated flex duct in 1940s-1960s homes loses insulation R-value and structural integrity in attics that routinely exceed 130°F. Joints separate. The inner liner tears. Humid attic air enters the supply stream.
- Condensation from failed seals near Brays Bayou. Outdoor relative humidity regularly above 85% means any duct seal failure becomes a persistent moisture source. We find mold colonization at collar joints where mastic was never applied or where tape has dried and peeled.
- Skipped systems in multi-zone homes. Larger West U builds often have three or more air handlers. Homeowners sometimes treat one system and assume the job is done. Each duct network is separate. A contaminated pathway in one system re-pollutes the others through shared return air or open doorways.
Pricing for Duct Repair & Sealing in West University Place, TX
A typical duct sealing job for a single-system home in West University Place runs $480-$720. Flex duct repair, when we’re replacing multiple runs in a bungalow attic, typically falls between $650 and $1,100 per system. Metal duct repair with mastic and reinforcement mesh ranges $380-$580 for accessible trunk line work. Duct insulation replacement, including the plenum and exposed trunk lines, usually runs $520-$840 per system.
These are whole-system prices, not per-vent teaser rates. In West U’s larger custom homes with three or more HVAC systems, each system is priced and documented separately - Haven Standard Clause 1 requires a written scope for every air handler before any panel comes off. What affects cost: accessibility of attic runs, extent of construction debris removal needed, whether we’re working in a 130°F attic or a conditioned mechanical room, and whether previous repairs used proper materials or shortcuts we’ll need to undo.
We do not quote per-vent prices. We do not offer $79 coupons that balloon once the truck arrives.

FAQs - Duct Repair & Sealing in West University Place

Yes, each system is priced separately because each has its own duct network, plenum, and set of joints to inspect and seal. A three-system home in West University Place typically runs $1,440-$2,160 for full sealing across all networks, or $1,950-$3,300 if we’re replacing degraded flex duct in multiple attics. We never lump systems together on a single vague scope - Haven Standard Clause 1 requires a written price per system before work begins, so you know exactly what each air handler costs to repair. Call (346) 423-3631 for an exact quote - estimates are free.
Because the ducts were never clean to begin with. West U’s teardown-and-rebuild cycle means HVAC systems are installed during active construction - drywall sanding, spray foam application, and blown-in insulation all happen while the ductwork is open. Drywall dust and foam overspray settle in trunk lines and supply boots, then blow into living spaces when the system first runs. We regularly find this debris in homes occupied less than six months. Sealing is equally critical: construction vibration loosens takeoffs and separates collar joints that were never properly mastic-sealed. Call (346) 423-3631 for an exact quote - estimates are free.
West U sits near Brays Bayou where outdoor relative humidity regularly exceeds 85%, and surviving 1940s-1960s bungalows have flex duct in unconditioned attics that amplifies every leak. When humid attic air enters a cold supply duct through a failed seal, the moisture condenses on the duct interior - creating the exact conditions mold needs. Mastic sealant is essential in this climate because it remains flexible and watertight through thermal cycling, unlike tape that dries and peels. We also inspect insulation integrity, since a bare or degraded duct jacket will sweat even if the joints are sealed. Call (346) 423-3631 for an exact quote - estimates are free.
First, a written price for the exact scope - Haven Standard Clause 1, no exceptions. Then our technician runs a camera through every accessible duct run and shows you what the lens sees: debris buildup, separated joints, degraded insulation, or construction debris. We photograph everything before touching it. The repair work follows the written scope exactly - mastic application, flex replacement, insulation install, or debris removal with negative-pressure extraction (a suction setup that pulls dislodged material into a HEPA-filtered collector rather than letting it escape into your home). Afterward, we run the camera again and deliver the before-and-after photo record as a standard job deliverable. The 365-Day Done Right Promise is documented in writing before we leave. Call (346) 423-3631 to schedule.
For new custom homes in West U, we recommend an initial inspection within the first year of occupancy - construction debris and vibration-loosened joints show up quickly. For mid-century bungalows with attic-routed flex duct, every two to three years given the 130°F+ summer heat and humidity stress. Any home with three or more systems should rotate inspections annually by system, so each network gets checked every three years without skipping. Visible dust from registers, uneven cooling between rooms, or a spike in electricity bills are immediate signals to call regardless of schedule. Call (346) 423-3631 for an exact quote - estimates are free.
