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 West University Place
Homeowners in West University Place call us for everything from West University Place Dryer Vent Cleaning to duct sealing that holds up to Houston’s humidity and the unique challenges of flood-prone ground. We’re familiar with the mix of 1920s bungalows along Wakeforest and the newer slab-on-grade builds near Weslayan Plaza, and we know the difference between a quick seal job and one that actually solves the problem. Our crews serve West University Place from our Houston dispatch office, and when you call (361) 326-5060, a live person answers – no voicemail loops, no callback queues.
Why Hollis Air Duct Cleaning Is West University Place’s Preferred Duct Sealing Company
We’ve been working in West University Place long enough to know which homes on Bissonnet sit on the highest water table and where the 1990s custom builds have flex duct that failed after Harvey. Our Duct Sealing in West University Place reputation comes from showing up inside the window, pricing in writing before we touch anything, and leaving the site clean. Every technician is background-checked and uniformed, and every job carries our 365-Day Done Right Promise in writing – if the seal fails or the moisture returns, we come back at no charge.
We don’t bait and switch with a low coupon price that balloons once we’re in your driveway. The price is written down before work starts, and it doesn’t move at the door. That’s The Garrison Standard, and it’s how we’ve operated since 2004.
Duct Sealing Services in West University Place
Duct Sealing Services in West University Place require more than mastic and mesh when you’re dealing with post-flood moisture trapped in slab-on-grade construction. We seal supply and return joints, boots, and plenum connections using mastic rated for high-humidity environments, but only after we’ve pressure-tested the system and mapped any moisture intrusion. A typical duct sealing job in West University Place runs $450 – $850 for a standard residential system, with larger homes or flood-damaged runs climbing to $1,200 – $1,800 when antimicrobial treatment and documentation for insurance are included.
Pressure Testing Before Sealing
We run a static pressure test on every system before we seal a joint. In West University Place’s newer airtight homes, sealing without checking return-side pressure can strain the blower motor and turn a leak into a mechanical failure. Our Nikro negative-air machines let us measure actual airflow loss, not guess at it.
Post-Flood Seal Protocol
After water intrusion, sealing alone traps contamination. We document moisture plumes with photos and thermal mapping, then seal only after the insurer has accepted the scope – or we rebuild the damaged runs first. This protects your claim and your air quality.

Duct Insulation in West University Place
Duct Insulation in West University Place fails differently than in drier climates. Our summer dew points regularly exceed 75°F, and condensation forms on any duct with compromised insulation – especially in the tight, energy-efficient new construction near University Boulevard where there’s no attic ventilation to absorb moisture. We replace waterlogged insulation with closed-cell foam or fiberglass wrap rated for flood-prone zones, then seal the vapor barrier to prevent the condensation cycle from restarting. Typical duct insulation work in West University Place runs $600 – $1,100 for partial replacement and $1,400 – $2,200 for full system reinsulation with sealing included.
Condensation-Resistant Materials
Standard duct wrap absorbs humidity like a sponge here. We use insulation products from Guardsman and Abatement Technologies that are rated for high-moisture environments and won’t degrade when the slab sweats.
Insulation Documentation for Claims
When floodwater reaches duct insulation, the material is compromised even if it looks dry. We photograph the flood line on the insulation, test for moisture content with a calibrated probe, and write up the findings so your adjuster has what they need.
Trusted Brands We Service in West University Place
We stock parts and materials from Rotobrush, Nikro, and Guardsman for West University Place jobs, which means faster turnaround when your system needs sealing or insulation replacement after a weather event. Our Rotobrush rotary brush systems clean duct walls before we seal them, and our Nikro negative-air machines maintain proper containment during the job. We also install Aprilaire filtration products to protect the sealed system going forward. You won’t wait on a parts order from out of state.
Common Duct Sealing Problems We See in West University Place Homes
- Sealing over flood-contaminated ducts without documentation. In West University Place’s post-Harvey rebuilds, we’ve found contractors who sealed ducts that had taken water through the return plenum. The insurer rejected the claim later, and mold returned to the same wall chase within one humid season.
- Aerosol sealant beading on saturated flex duct. The 1920s – 1950s bungalows near Wakeforest often have flex duct off the air handler where condensation already pools in low spots. Aerosol sealant can’t bridge a wet surface; it beads and peels within months.
- Tightening ducts without checking blower static pressure. West University Place’s newer airtight homes have less tolerance for pressure changes. Seal the leaks without measuring first, and the blower motor strains against the restriction.
- Ignoring slab moisture in slab-on-grade construction. On Houston’s most flood-prone ground, water vapor moves through the slab and into wall chases. Seal the ducts without pressure-mapping the slab, and you’ve capped the moisture inside with nowhere to go.
Pricing for Duct Sealing in West University Place, TX
A standard duct sealing job in West University Place runs $450 – $850 for a typical single-system home. Larger homes, complex duct layouts, or jobs requiring access through finished ceilings push toward $1,200. When flood damage is involved and we need to document for insurance, add antimicrobial treatment and moisture mapping for $300 – $600 more. Full duct insulation replacement with sealing runs $1,400 – $2,200.
What moves the price: accessibility (crawl space versus attic), the extent of leakage found during pressure testing, whether flood documentation is required, and whether we’re working around historic preservation constraints in the older bungalow district. We give you one flat price per system, agreed in writing before we start. No per-vent pricing, no add-ons at the door.

FAQs About Duct Sealing in West University Place
It depends on where the flood line reached. If water touched the duct insulation or entered the return plenum, replacement is typically required – we document this with photos and moisture readings so your insurer accepts it. If the flood only affected the exterior of sealed metal duct with intact insulation, cleaning and sealing may suffice. Call (361) 326-5060 and we’ll inspect to give you a straight answer.
We photograph the flood line on duct insulation, run camera inspection through supply and return runs, map moisture plumes on the slab with thermal imaging, and write a scope that cites NADCA standards. This documentation package is what gets claims approved. We do this before we seal or replace anything.
Newer airtight construction traps moisture with nowhere to escape, so any residual water in the duct system stays there and degrades the sealant from behind. Older homes “breathe” more, which actually helps seals dry out. In West University Place’s post-Harvey luxury builds, we always pressure-map the slab and wall chases before sealing.
Yes, and we test for this before we seal. The 1920s – 1950s bungalows often have blower motors already working at capacity. We measure return-side static pressure, then seal in stages and retest so we don’t trade a leak for a motor burn-out.
It can. Modifications to duct systems in historic district bungalows may require documentation to city preservation standards. We handle this as part of our scope write-up, which also supports your insurance claim if flood damage is involved.
