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 Richwood
Richwood’s Gulf Coast position means your ductwork battles salt air and humidity every single day. A typical duct sealing job in Richwood runs $450 – $850 for a whole-home system, and most homes here need it more than owners realize. We’re the Duct Sealing team that understands why a 1970s ranch on Brazosport Boulevard loses conditioned air differently than a newer build near the water.
Our dispatch office coordinates crews from Dallas-Fort Worth, and we’ve got technicians on the road to Richwood regularly. When you call (361) 326-5060, a live person answers, day or night. No voicemail, no callback queue, no waiting until Monday to get on the schedule.
Why Hollis Air Duct Cleaning Is Richwood’s Preferred Duct Sealing Company
We’ve been sealing ducts since 2004, and the Garrison Partners family of businesses has built its name on one thing: doing what we said we’d do. In Richwood, that means showing up inside the quoted window, pricing the job in writing before we touch your system, and leaving the site clean. That’s The Garrison Standard, and it’s how every Hollis crew operates.
Richwood homeowners call us because they’ve dealt with the alternative. A crew quotes low over the phone, then the invoice doubles once they’re in your attic. We don’t work that way. The price is written down before any work starts, and it does not move at the door. Our 365-Day Done Right Promise backs every sealing job in writing: if the repair fails within a year, we return and make it right at no charge, including a free second visit.
Our technicians are background-checked and uniformed. You know who’s walking into your home before they arrive. And we carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, the same tools commercial crews use on larger facilities.
HVAC Duct Sealing in Richwood
HVAC Duct Sealing in Richwood addresses a problem most homeowners don’t know they have: conditioned air escaping through gaps, disconnected joints, and deteriorating mastic in duct runs that were never designed for decades of Gulf Coast humidity. In a town where many homes were built slab-on-grade in the 1970s and 1980s with original flex duct stashed in hot attics, sealing isn’t maintenance, it’s correction of accumulated failure.
We seal supply and return plenums, register boots, and longitudinal seams using duct sealing mastic and reinforced mesh tape, not the cheap foil tape that peels off in humid conditions. For inaccessible sections, we apply aerosol-based sealant that finds leaks from the inside. A typical whole-home sealing in Richwood runs $450 – $850 depending on system size and access difficulty.
When Sealing Beats Replacement
Not every leaky duct needs tearing out. If your flex duct is intact but poorly connected at the plenum, targeted sealing restores efficiency for a fraction of replacement cost. We inspect first, photograph what we find, and show you before we recommend anything.
Salt Air and Duct Degradation
Richwood’s proximity to the Gulf means salt-laden air infiltrates attic vents and corrodes metal duct components. Sealing the duct envelope also seals out that corrosive atmosphere, extending system life in ways that matter specifically here.
Duct Repair in Richwood
Duct Repair in Richwood often means fixing what coastal conditions have damaged: crushed flex duct from workers in the attic, disconnected runs that have pulled apart under thermal expansion, or water-damaged sections where roof leaks or condensation have saturated insulation. We see these patterns repeatedly in the older ranch homes near Main Street and the waterfront properties along Oyster Creek Drive.
Our crews carry replacement flex duct, metal fittings, and insulation wrap sized for residential systems. Most repairs run $200 – $500 for isolated section replacement, or $600 – $1,200 when multiple runs need attention. We price by the job, not by the linear foot, so you’re not watching a meter run while we work.
Disconnected Runs and Air Loss
A duct that’s pulled completely loose from the plenum dumps all its conditioned air into your attic. In summer, that’s $300+ a year in wasted cooling. We reconnect, support, and seal these runs so they stay put.
Moisture-Damaged Ductwork
Humid attic air condenses on cool duct surfaces, saturating insulation and breeding mold. We replace damaged sections and improve vapor sealing so the problem doesn’t repeat next season.
Trusted Brands We Service in Richwood
We stock parts and use equipment from Aprilaire, Abatement Technologies, and Guardsman on Richwood jobs. Aprilaire media air cleaners integrate well with sealed duct systems, capturing what leaks no longer let bypass. Abatement Technologies HEPA filtration equipment protects your home during repair work. Guardsman products finish the job with durable surface treatments. Because we carry common fittings and sealants on every truck, most Richwood repairs don’t wait for parts orders. Our technicians know which Ranch Country homes have the tight attic access that requires specific flex duct diameters, and they come prepared.
Common Duct Sealing Problems We See in Richwood Homes
- Original mastic turned to dust. The fiberglass duct board and metal joints in 1970s Richwood ranches were sealed with water-based mastic that crumbles after forty years of heat cycling. We scrape the old material and apply fresh, fiber-reinforced sealant rated for humid attics.
- Flex duct crushed by storage or foot traffic. Attics in slab-on-grade homes become default storage spaces. A box or plywood sheet laid across a flex run pinches airflow and creates back pressure that blows out weak joints elsewhere.
- Salt deposits at return air pathways. Poorly sealed return plenums in coastal Richwood pull outdoor air through exterior wall cavities, depositing fine salt that corrodes metal fittings and contaminates indoor air. Sealing the return side is as critical as sealing supplies.
- Tropical storm aftermath. After power outages and high humidity events, we see surges of calls from Richwood homeowners noticing musty odors. Often the odor source is mold in saturated duct insulation, but the root cause is leaky ducts that let humid attic air migrate inward continuously, not just during storms.
Pricing for Duct Sealing in Richwood, TX
Whole-home duct sealing in Richwood typically runs $450 – $850. Isolated repairs or partial sealing of problem zones start around $200. What moves you within that range: system size (a 3-ton system has more ductwork than 2-ton), attic access difficulty (tight crawlspaces under slab homes take longer), and whether we find disconnected runs that need reconnection before sealing can begin.
We don’t quote per-vent or per-linear-foot. One flat price per system, agreed before work starts. You’ll get a written price on site, and that number doesn’t change when we’re halfway through the job. Estimates are free. Call (361) 326-5060 to schedule.
