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 Yardley
We dispatch our Duct Sealing crews to Yardley from our Philadelphia scheduling office, and most calls from the borough and surrounding Bucks County neighborhoods get a visit inside a few business days. Yardley’s mix of river-adjacent ranches from the Levitt era and the sprawling colonials in Makefield Glen means we’ve sealed ductwork in just about every configuration this side of the Delaware. If your upstairs rooms never reach the thermostat setting, or your basement ductwork smells musty after spring rains, the leaks are usually findable and fixable in a single visit. Call (361) 326-5060 for a free written estimate before any work starts.
Why Hollis Air Duct Cleaning Is Yardley’s Preferred Duct Sealing Company
We’ve been part of the Garrison Partners family since 2004, and our technicians have worked in enough Yardley homes to know the difference between a 1962 split-level near the canal and a 2004 colonial off Edgewood Road without being told. That matters because the sealing approach for galvanized trunk lines with asbestos-wrapped joints is not the same as sealing modern flex duct with failing collars in a 3,500-square-foot attic run.
Our crews arrive in uniform, background-checked, and inside the quoted window. The price is written down before we touch anything, and it does not move at the door. Every duct sealing job in Yardley carries our 365-Day Done Right Promise: if the seal fails or the airflow problem returns within a year, we come back and make it right at no charge, including a free second visit. Phones are answered by a live person 24 hours a day, seven days a week, not a callback queue.
We also handle Air Duct Cleaning in Yardley and Dryer Vent Cleaning in Yardley for homeowners who want the full system addressed in one scheduled visit.
HVAC Duct Sealing in Yardley
HVAC Duct Sealing in Yardley typically addresses the conditioned air leaking from gaps, disconnected joints, and deteriorated mastic in forced-air systems, with most homeowners in the borough paying between $450 and $1,200 depending on the size of the house and the accessibility of the duct runs. In the older river-adjacent neighborhoods, we often find original galvanized ducts with separated seams and failed tape, while the large colonials in Yardley Hunt and Makefield Glen frequently have flex duct collars that have pulled loose in hot attics.
The work involves pressurizing the system to locate leaks, sealing accessible joints with mastic or metal-backed tape rated for ductwork, and reconnecting separated sections. We use professional-grade equipment from Rotobrush and Abatement Technologies to verify airflow improvement before we leave.
When Sealing Beats Replacement
Most Yardley homes built between 1950 and 1980 have ductwork that is structurally sound but poorly sealed. If your metal ducts are intact and not rusted through, sealing returns more value per dollar than a full replacement. We test static pressure and temperature split to confirm the improvement in writing.
Attic Flex Duct in Newer Subdivisions
The long flex duct runs in Makefield Glen and similar developments were often installed quickly during the building boom and never properly sealed at trunk connections. We find 15-20% airflow loss as standard in these homes. Sealing the collars and adding support straps where flex has sagged usually solves it.
Duct Repair in Yardley
Duct Repair in Yardley covers the physical fixes that sealing alone cannot address: crushed or disconnected flex duct, rusted-out galvanized sections, damaged dampers, and failed insulation that lets attic air heat or cool the duct before it reaches your rooms. Most repairs in the borough run $300 to $800 for localized fixes, with larger sectional replacements in big colonial systems reaching $1,500 to $2,400.
After wet springs, we regularly find basement and crawlspace ductwork in the older borough neighborhoods with corrosion from seasonal dampness. The river-valley humidity here is not abstract; it shows up as pinhole rust in metal ducts and collapsed flex duct in saturated crawlspaces.
Rust and Corrosion Near the Delaware
Homes within a few blocks of the river or the Delaware Canal see basement ductwork that corrodes faster than upland properties. We replace rusted sections with galvanized metal or insulated flex, depending on access, and we always check the surrounding trunk for early failure.
Collapsed Flex Duct in Crawlspaces
In the low-lying areas near Lake Afton and the borough’s southern edge, crawlspace flex duct often sits on damp ground or gets crushed by improper support. We rehang with proper strapping and replace water-damaged sections, then verify airflow at each register.
Trusted Brands We Service in Yardley
We carry sealing and filtration products from Aprilaire, Abatement Technologies, and Guardsman on our trucks, which means most Yardley repairs do not wait for parts orders. Our technicians use Rotobrush rotary systems and Nikro negative-air machines when duct cleaning accompanies sealing work, and we stock Honeywell media filters for homeowners who want better filtration after the leaks are fixed. Having the right material on hand matters in Yardley, where a humid summer week with leaky ducts can push indoor humidity past what your dehumidifier can handle.
Common Duct Sealing Problems We See in Yardley Homes
- River-valley dampness corroding basement metal ducts. The older ranches and split-levels near the Delaware routinely show rust at seam joints that were never properly sealed originally. We find this especially in homes south of Main Street where the water table sits higher.
- Building-boom flex duct with failing collars in Makefield Glen and Yardley Hunt. The rapid construction of the late 1990s and early 2000s meant long flex runs with minimal support. Collars loosen, ducts sag, and conditioned air leaks into attics before it reaches the second floor.
- Asbestos-wrapped galvanized trunk lines in pre-1970 homes. We do not disturb asbestos, but we can seal accessible joints downstream and improve airflow without touching wrapped sections. This requires a careful inspection that many cheaper outfits skip.
- Musty microbial growth in floodplain ductwork after wet springs. Yardley’s riverside neighborhoods see basement and crawlspace ducts that hold moisture long after the rain stops. Sealing helps, but we always inspect for growth that needs remediation first.
Pricing for Duct Sealing in Yardley, PA
A typical duct sealing job in Yardley runs $450 to $1,200 for whole-system work in a standard single-family home. Localized repairs in accessible basements or crawlspaces usually fall in the $300 to $800 range. Large colonial systems in Makefield Glen or Yardley Hunt with extensive attic duct networks can reach $1,500 to $2,400 if we are replacing multiple sections of flex duct and resealing the entire trunk line.
What moves the price: the linear footage of ductwork, whether we need to access attic or crawlspace runs, the condition of existing mastic and tape, and whether we find corrosion or damage that requires sectional replacement rather than sealing alone. We give you one flat price per system, agreed in writing, before any work begins. No per-vent pricing, no add-ons at the door. Call (361) 326-5060 for a free estimate.
