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 Aldine
We dispatch crews to Aldine from our Houston office, and we’re on the road to neighborhoods like Westfield, Keith-Wiess Park, and the East Aldine District daily. If your ducts are leaking conditioned air into the attic or crawl space, you’re paying to cool and heat square footage you don’t live in. Call us at (361) 326-5060 for a free estimate with a written price before any work starts.
Aldine’s older housing stock, much of it built between the 1960s and 1980s, wasn’t designed for the multi-system setups many homeowners run now. When we seal ducts here, we scope and price per system, not as one vague whole-house number. That’s how we avoid the shortcut of sealing only the easy-to-reach runs while leaving deteriorated trunk lines to keep bleeding air.
Why Hollis Air Duct Cleaning Is Aldine’s Preferred Duct Sealing Company
We’ve been part of the Garrison Partners family since 2004, and our Duct Sealing in Aldine work is built on the same standard: arrive inside the window, price in writing, complete the job by the book, leave the site clean. Our technicians are background-checked and uniformed, and our phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues.
Homeowners in Aldine choose us because we’ve seen what happens when duct sealing is treated as a quick spray-and-go job. In a 1970s ranch off Richey Road near the Eastex Freeway, we found two original galvanized trunks retrofitted with a third system for a converted garage. The 1980s flex runs were sagging and pulling loose at the collars, feeding dust into the return plenum while the blower motor short-cycled from static pressure. We sealed the collars and boots, then handed over before/after air handler photos and labeled static readings for each of the three systems – one binder page per system. That’s what a three-system house in Aldine requires.
Every repair we make carries our 365-Day Done Right Promise in writing. If the work fails within a year, we return and make it right at no charge, including a free second visit.
HVAC Duct Sealing in Aldine
HVAC Duct Sealing in Aldine addresses the pressurized leaks in your supply and return ductwork that waste conditioned air and pull attic dust, humidity, and pollutants into your living space. In Aldine’s pre-1990 housing stock, original galvanized or early flexible ductwork sized for a single system is common, so three-system homes are usually retrofits. Sealing must be scoped, priced, and documented per system rather than as one blended whole-house job.
A typical HVAC duct sealing job in Aldine runs $450 – $850 per system depending on accessibility, the condition of existing ductwork, and whether mastic sealing, metal tape, or collar replacement is required. Whole-home jobs on single-system houses start around $350 for straightforward register and boot sealing.
When Sealing Becomes Repair
Not every duct can be sealed. Galvanized steel from the 1960s – 1980s corrodes from the inside out in Houston’s humidity, and flex duct sags, tears, or delaminates. We inspect with a Rotobrush camera before quoting. If the trunk is structurally failed, we quote repair or replacement separately, never bury it inside a sealing price.
Static Pressure Documentation
After sealing, we measure static pressure at the air handler for each system and record before/after readings. In Aldine’s multi-system homes, this is the only way to prove the seal held and the blower isn’t fighting restriction. You get a labeled printout per system, not a handshake.
Duct Repair in Aldine
Duct Repair in Aldine replaces or rebuilds sections of ductwork that have deteriorated beyond what sealing can fix. Original galvanized trunks in Aldine’s 1960s – 1980s housing corrode from condensate and humidity. Flex duct collapses, delaminates, or gets chewed by rodents in pier-and-beam crawl spaces. We cut out failed sections and fabricate replacements with proper slope, support, and insulation.
Typical duct repair in Aldine runs $300 – $600 per section for accessible trunk replacement, or $150 – $350 per flex run. Major trunk rebuilds on older systems can reach $800 – $1,400 depending on length and material. We always price per section, in writing, before cutting.
Galvanized Trunk Replacement
Original galvanized steel ductwork in Aldine homes often shows pinhole corrosion and separated seams where mastic has dried and cracked. We replace failed trunk sections with insulated flex or sheet metal, properly supported and sealed. The work is photographed and the new static pressure recorded.
Flex Duct and Collar Work
Retrofitted systems in Aldine, especially garage conversions and additions, often use flex duct that sags between supports or pulls loose at takeoff collars. We re-support with proper straps, replace crushed or torn runs, and seal collars with mastic and mechanical fasteners, not just tape.
Trusted Brands We Service in Aldine
Our crews carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, plus filtration and sealing products from Guardsman. For Aldine homeowners, this means we don’t drive back to Houston for parts mid-job. We stock mastic, metal tape, insulated flex, and collar fittings for the galvanized and early flex systems common in this market. Rotobrush camera systems let us document the full length of runs under slab and pier-and-beam homes, where homeowners can’t follow. Guardsman sealing products are rated for the humidity and temperature swings of Houston-area attics. If your system needs a component we don’t stock, we order it and schedule the return visit, not bill you for our supply run.
Common Duct Sealing Problems We See in Aldine Homes
- Visible register sealing while trunk lines rot. Some crews seal only the supply and return ducts at the registers, leaving deteriorated 1960s – 1980s galvanized trunk sections unsealed. The humid Houston air keeps feeding mold growth downstream regardless, and your blower still works overtime.
- Blended whole-house pricing on multi-system homes. Pricing duct sealing as one figure on Aldine’s retrofitted three-system houses means leaky secondary or garage-conversion systems get skipped. The homeowner never learns which of their three systems was actually addressed, and the invoice doesn’t say.
- Missing camera inspection on hidden runs. Long duct runs under pier-and-beam or slab homes in Aldine can’t be eyeballed. Skipping camera inspection and NADCA-standard documentation leaves the homeowner with no evidence for work on ductwork they can’t see and can’t verify.
- Eastex Freeway corridor particulate loading. Proximity to the Eastex Freeway and nearby industrial corridors means airborne particulate matter settles in ductwork at higher rates than in suburban areas with better air quality. Leaky return systems pull this directly into the home, making tight seals more critical here than in cleaner-air zip codes.
Pricing for Duct Sealing in Aldine, TX
Duct sealing in Aldine typically runs $350 – $850 per system depending on what we’re working with. A single-system home with accessible registers and boots might run $350 – $550 for full mastic sealing and collar tightening. Multi-system retrofits with original galvanized and added flex runs run $650 – $850 per system because each requires separate scoping, camera inspection, and static documentation. Duct repair, when needed, adds $300 – $600 per section.
What moves the price: accessibility (attic vs. crawl space), the condition of existing ductwork, whether we’re sealing or replacing failed sections, and the number of systems. We give one flat price per system, agreed in writing before work starts. No per-vent pricing, no add-ons at the door. Call (361) 326-5060 for an exact quote – estimates are free.

FAQs About Duct Sealing in Aldine
We quote per system, always. Aldine’s pre-1990 housing stock often still runs original galvanized or early flexible ductwork sized for a single system, so three-system homes here are usually retrofits. Pricing per system ensures each unit gets its own camera inspection, sealing scope, and static pressure documentation. Call (361) 326-5060 and we’ll walk through your setup.
It depends on the condition of the metal. Surface corrosion and separated seams can often be sealed with mastic and mechanical reinforcement. Pinhole corrosion through the wall of the trunk, or structural collapse from rust, requires section replacement. We camera-inspect before quoting so you know which you’re getting. Call (361) 326-5060 to schedule.
You should receive before/after camera images of the full run, labeled static pressure readings at the air handler for each system, and a written description of what was sealed or replaced. In Aldine’s pier-and-beam and slab homes, this documentation is the only proof the work happened on runs you can’t access yourself. We provide one binder page per system.
Every 5 – 7 years for homes in the Eastex Freeway corridor with higher particulate loading, or sooner if you notice dust buildup, humidity issues, or blower short-cycling. Aldine’s subtropical humidity accelerates mastic aging and flex duct deterioration compared to drier climates. Call (361) 326-5060 if you’re unsure when your ducts were last inspected.
Yes. We measure static pressure across the system before and after sealing. Elevated static pressure often indicates the blower is compensating for leaks by pulling harder against restricted or imbalanced airflow. In Aldine’s older systems with retrofitted additions, we frequently find one system running 0.3 – 0.5 inches WC high because flex runs have pulled loose at collars. After sealing, the static drops and the blower cycles normally.
