Our Duct Repair & Sealing Services in Timberwood Park
Duct Sealing
Leaky ducts waste 20–30% of conditioned air in a typical Timberwood Park home before it ever reaches the vent. We pressure-test your system, locate every breach, and seal with mastic compound or metal-backed tape rated for Texas attic heat. In Timberwood Park’s large custom homes — often 3,000+ square feet with duct runs stretching 50+ feet — even small leaks compound into major efficiency losses. We seal them permanently.
Flex Duct Repair
This is our most common Timberwood Park call. Homes built here between 1995 and 2010 were fitted with long flex-duct runs that sag, kink, and separate at connections after 15–25 years of attic heat cycling. We repair sections where possible, replace where the inner liner has torn, and support new runs with proper strapping so they don’t sag again. Equipment built for this job — our Nikro duct-replacement tools handle tight attic spaces without crushing the new flex.
Metal Duct Repair
Some Timberwood Park homes, particularly larger custom builds, use galvanized trunk lines with flex takeoffs. We repair separated seams, corroded sections, and failed dampers. Metal work requires different techniques than flex — we weld-patch or replace sections, then seal with mastic rated for metal-to-metal joints.
Duct Insulation & Mastic Sealant
Timberwood Park’s dense tree canopy traps humidity against rooflines. When your AC cycles off, warm moist air settles in uninsulated ducts and condenses. We reinsulate with R-6 or R-8 wrap and apply mastic sealant at every joint — the combination stops both air loss and moisture intrusion. Last March, our crew sealed a multi-zone flex-duct system on Crested Butte Trail in Timberwood Park. The 20-year-old ducts had sagged at connections, and the return plenum was coated with a pale cedar-pollen dust that had bypassed the standard filter. We mastic-sealed every joint, replaced four sections of flex duct, and installed an Aprilaire media filter cabinet to capture the fine juniper particles — the homeowner reported near-immediate relief from seasonal allergy symptoms.

Trusted Brands We Service in Timberwood Park
We stock and install Honeywell, Aprilaire, and Guardsman products on every Timberwood Park job. For cedar-pollen filtration specifically, we recommend Aprilaire’s 4-inch pleated media cabinets — they capture particles down to 0.3 microns, which includes juniper pollen. We keep common sizes in stock, so Timberwood Park customers don’t wait for special orders. Fast turnaround matters when you’re breathing cedar dust through February.
Common Duct Repair & Sealing Problems We See in Timberwood Park Homes
- Sagging flex ducts in 20-year-old attic runs. Timberwood Park’s custom homes from the late 1990s and 2000s have flex duct that has softened, sagged between supports, and pulled loose at collars. Air leaks into the attic; your bedroom stays hot.
- Cedar-pollen infiltration coating duct interiors. The Ashe junipers on your own lot produce microscopic pollen that standard 1-inch filters miss. It accumulates on duct walls, recirculates all winter, and prevents sealants from bonding properly until we clean it out.
- Condensation and mold in humid attic conditions. Timberwood Park’s tree canopy holds moisture against rooflines. When attic ducts cool below dew point, water forms on the exterior, soaks insulation, and breeds mold that you’ll smell every summer.
- Disconnected return plenums pulling in attic air. In Timberwood Park’s large homes with multiple HVAC zones, return plenums often separate from the main trunk. Your system “returns” 130°F attic air instead of conditioned air — efficiency crashes, and cedar pollen comes with it.

FAQs — Duct Repair & Sealing in Timberwood Park
It’s Ashe juniper — mountain cedar — pollen from the trees on and around your property. The microscopic particles slip through standard 1-inch filters and coat duct interiors from December through February. We see this distinctive pale dust in Timberwood Park ducts every late winter; it’s virtually absent in treeless south San Antonio subdivisions. We clean it out completely before sealing, then upgrade your filtration to capture it. Call (844) 886-2161 — estimates are free.
Usually, yes. We can re-support and reconnect sagging sections if the inner liner is intact. Where flex has torn or the insulation is water-damaged, we replace individual runs rather than the whole system. Timberwood Park’s 2,500–4,500 sq ft homes often have 4–6 zones, so targeted repair saves thousands over full replacement. Call (844) 886-2161 and we’ll inspect what’s actually failing.
Yes. We use mastic sealant rated for wet conditions and always pair sealing with proper insulation wrap. Timberwood Park’s canopy-trapped moisture creates condensation inside ducts when systems cycle; uninsulated sealed ducts will still grow mold. Our process addresses both air leakage and thermal bridging. Call (844) 886-2161 for a humidity-specific assessment.
Aprilaire 4-inch pleated media cabinets, which we install and stock. They capture particles at 0.3 microns — juniper pollen averages 20–30 microns, so these filters stop it before it enters your ductwork. Honeywell electronic air cleaners are an alternative for severe allergy sufferers. Call (844) 886-2161 and we’ll size the right unit for your system.
Yes, if the smell is coming from mold in your ducts. Sealing alone won’t fix it — we need to clean the contamination first, then seal and reinsulate to prevent moisture from re-entering. Timberwood Park’s humidity pattern makes this a recurring issue; our combined clean-seal-sanitize protocol breaks the cycle. Call (844) 886-2161 for an inspection.
