Why Lone Star Air Duct Cleaning Service Houston Is West University Place’s Preferred Duct Repair & Sealing Company
We’ve built our reputation in West University Place one job at a time. Owner Scott Gray personally leads every duct repair call — he’s the technician who shows up at your door, not a rotating subcontractor. That matters here, where homes demand real diagnostic skill, not guesswork.
Our 433 verified reviews average 4.9 stars, and a significant share come from repeat customers right here in West University Place. They mention the same things: Scott spotted problems others missed, explained the repair clearly, and the fix held up.
Response time matters in this market. We’re based in Houston and route directly to West University Place — no dispatch delays, no crews driving in from the suburbs. Most repair calls are assessed same-day, and we carry the parts and materials to complete standard sealing and flex duct repairs on the spot.
We also understand the local building context. West University Place’s housing stock — those 1930s–1960s brick bungalows and the newer teardown-rebuilds — presents duct configurations we see nowhere else. That local fluency saves time and prevents misdiagnosis.
Our Duct Repair & Sealing Services in West University Place
Duct Sealing with Mastic Sealant
Mastic sealant is our standard for West University Place homes, and there’s a reason. The patchwork duct systems common here — original galvanized steel spliced into 1970s flex duct during renovations — create joints that standard foil tape can’t handle long-term. Tape fails where dissimilar materials expand and contract at different rates, especially in Houston’s relentless humidity. Mastic remains flexible, fills irregular gaps, and bonds to both metal and flex surfaces. A typical mastic sealing job for a 2,000-square-foot West University Place home runs $280–$420.
Metal Duct Repair
The surviving galvanized ductwork in pre-WWII and mid-century West University Place homes is often worth preserving — when it’s accessible and structurally sound. We’ve repaired original metal trunk lines in bungalows near College Street and Auden Street, patching corrosion spots, reinforcing weak seams, and transitioning properly to newer flex runs. Metal duct repair here typically ranges from $180 for spot welding and patching to $480 for section replacement with custom-fabricated galvanized fittings. We don’t replace metal that can be saved; we don’t patch metal that’s too far gone.
Flex Duct Repair and Replacement
Flex duct in West University Place homes usually dates to 1970s–1990s renovations and shows predictable failure modes: collapsed inner liners, torn insulation jackets, and — especially in post-Harvey homes — mold contamination at low points where water collected. We replace damaged flex with properly sized, insulated runs, support them to prevent sagging, and seal all connections with mastic. Flex duct replacement in West University Place typically runs $140–$280 per run depending on length and attic access difficulty.
Duct Insulation
West University Place’s low-lying topography and Houston’s ambient humidity create chronic condensation issues at poorly insulated duct joints. This isn’t a seasonal problem — it’s year-round. We install proper R-6 or R-8 insulation on new and repaired runs, with particular attention to transitions in unconditioned attics where sweating starts. Duct insulation work ranges from $160 for targeted spot insulation to $520 for full trunk line rewrap in larger homes.

Common Duct Repair & Sealing Problems We See in West University Place Homes
- Tape failure at galvanized-to-flex transitions. Previous repairs in West University Place bungalows often used standard foil tape on mismatched materials. The tape loosens within one humid season, leaks return, and energy bills creep up. We remove the tape entirely and apply mastic for a permanent bond.
- Hidden mold in post-Harvey return boot connections. Even homes that passed official remediation frequently missed duct interiors. We regularly find visible microbial growth at the lowest supply runs and return boot connections — spots where floodwater sat longest. Standard dryout protocols didn’t address these spaces.
- Condensation and sweating at uninsulated attic joints. West University Place’s elevation and Houston’s humidity mean ducts in unconditioned spaces run cold against saturated air. Without proper insulation and mastic sealing at every joint, condensation pools, insulation degrades, and mold follows within a single cooling season.
- Collapsed or kinked flex duct from 1980s renovations. The flex runs installed during that era’s piecemeal upgrades weren’t always properly supported. Sagging creates turbulence, reduces airflow to distant rooms, and traps debris where cleaning tools can’t reach.

FAQs — Duct Repair & Sealing in West University Place
Visible damage is rarely the full extent of the problem in flooded WUP homes. We inspect the entire low-lying return system with borescope cameras, because microbial growth frequently extends past what eye-level inspection reveals. Replacement of all flood-exposed lower runs is often the prudent choice — patch repairs leave residual contamination that re-spreads once the HVAC runs. Call (855) 683-5929 for a full scope assessment; estimates are free.
Mastic adheres to both metal and flex surfaces, remains flexible through thermal cycling, and fills irregular gaps that tape bridges poorly. In West University Place’s high-humidity environment, tape adhesive degrades rapidly; mastic cures to a durable, vapor-resistant seal. We apply it with a brush at every joint, then inspect after curing. For a quote on mastic sealing your system, call (855) 683-5929.
We evaluate original metal ductwork section by section. Salvageable galvanized trunk lines — common in 1940s–1950s West University Place homes near Rice Boulevard — can be repaired, properly sealed, and integrated with new flex runs to additions. We only recommend full replacement when metal is extensively corroded or access for proper sealing is impossible. Scott Gray assesses this personally on every remodel consultation. Call (855) 683-5929 to schedule.
Signs include: musty odors when the HVAC starts, visible water staining on ceiling diffusers, uneven cooling between rooms, or insulation that compresses or crumbles when touched. In West University Place specifically, insulation that was wet during Harvey but appeared to dry may still harbor mold inside the vapor barrier. We inspect with moisture meters and thermal imaging. Call (855) 683-5929 for a no-charge evaluation.
Yes — we access most duct systems through existing attic hatches, crawl spaces, or mechanical chases. For West University Place teardown-rebuilds with finished basements or complex ceiling details, we use remote-sealing techniques and targeted access points. We don’t cut finished surfaces without explicit homeowner approval and a clear repair plan. Call (855) 683-5929 to discuss your home’s specific layout.
