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 Richboro
Duct sealing in Richboro typically runs $450 – $850 for a whole-house seal, and most jobs are completed in a single visit. If you’re noticing uneven temperatures between rooms, dust that returns within days of cleaning, or utility bills that climb every summer and winter, your ductwork is likely leaking conditioned air into your attic, crawlspace, or walls.
We’ve been sealing ducts in Richboro long enough to know the local housing stock inside and out. From the original ranches along Bustleton Pike to the newer colonials in Richboro Farms and Spring Mill, our crews have found the same pattern: ducts that were never properly sealed at installation, now working against homeowners through every humid Pennsylvania summer and dry, cold winter. Scheduling is coordinated from our Philadelphia office, but our technicians live and work in the Bucks County area, so we’re familiar with the township permit requirements and the quirks of Northampton Township construction.

Why Hollis Air Duct Cleaning Is Richboro’s Preferred Duct Sealing Company
Our reputation in Richboro was built on showing up inside the window we quoted and leaving with the job done by the book. That’s The Garrison Standard, and it’s how every Hollis location operates, including ours serving Richboro.
Homeowners here talk. We’ve earned repeat calls from neighbors in Richboro Farms who recommended us down the street, and from split-level owners near Tyler State Park who had enough of cold bedrooms in January. Our technicians are background-checked, uniformed, and arrive with the same professional-grade equipment we use on commercial jobs: Rotobrush rotary systems, Nikro negative-air machines, and sealing products from Abatement Technologies and Guardsman. The price is written down before any work starts, and it does not move at the door.
Our 365-Day Done Right Promise covers every duct sealing job in writing. If the seal fails within a year, we return and make it right at no charge, including a free second visit. No negotiation, no runaround.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday to schedule.
Duct Repair in Richboro
Duct Repair in Richboro addresses the physical damage that makes sealing impossible until the ductwork itself is sound. In the 1960s ranches and split-levels near Bustleton Pike, we regularly find galvanized steel trunks with rusted-out sections, flex duct that’s been crushed by storage items in attics, or sagging runs where the original support straps have failed. A typical duct repair in Richboro runs $200 – $500 for isolated fixes, or $600 – $1,200 when multiple sections need replacement before sealing can begin.
Disconnected Joints and Collapsed Runs
In the Spring Mill subdivisions, longer duct runs through unfinished attics mean more joints and more opportunities for separation. We reconnect and support these runs properly before any sealing work begins, because sealing a disconnected duct just traps air in your insulation.
Construction Debris in Older Systems
The older Richboro neighborhoods are a special case. Return-air ducts in these homes often share joist bays with the original hardwood-floor system, and we still find sawdust, nails, and occasionally forgotten tools from the 1960s build sitting in trunk lines. We clear this debris before repair and sealing so your system moves air, not history.
Air Duct Sealing in Richboro
Air Duct Sealing in Richboro closes the gaps, cracks, and failed joints that leak your conditioned air into spaces where you don’t live. Our crews use mastic sealant and metal-backed tape rated for duct applications, not the hardware-store tape that dries out and fails. A typical whole-house duct sealing in Richboro runs $450 – $850, with larger homes or systems requiring extensive prep work reaching $900 – $1,400.
Mastic Sealing for Lasting Results
We apply duct sealing mastic, a thick, fiber-reinforced compound that remains flexible after curing. In Richboro’s climate, this matters: the expansion and contraction from summer humidity to winter dryness will crack rigid sealants, but mastic moves with the metal. We follow this with mechanical fasteners where joints are under stress.
Pressure Testing After the Seal
After sealing, we run a pressure test to measure leakage against the total system airflow. You’ll see the before and after numbers in writing. In homes near the former farmland and wooded tracts, where fine soil dust and tree pollen have been accumulating for decades, this verification step confirms you’re moving air through the ducts, not pulling it from your crawlspace.
Trusted Brands We Service in Richboro
Our vans carry sealing and repair materials from Abatement Technologies and Guardsman, plus the Rotobrush and Nikro equipment we use for the cleaning and prep work that precedes a proper seal. We don’t make a second trip for parts because we stock what Richboro’s housing stock demands: mastic rated for residential ductwork, metal-backed tape that won’t fail in attic heat, and replacement flex duct in common diameters. If your system uses Honeywell or Aprilaire filtration components, we can inspect and advise on those during the same visit. The goal is one trip, one written price, one job done right.
Common Duct Sealing Problems We See in Richboro Homes
- Original flex duct crushed in attic storage areas. In the 1990s colonials of Richboro Farms, homeowners often use attic space for seasonal storage, and the original flex duct wasn’t routed to survive a stack of bins. We reroute or replace these runs with proper support before sealing.
- Failed tape at plenum connections. The tape used in original construction dries and peels, especially where summer humidity attacks the adhesive. We find this at every system age in Richboro, but it’s epidemic in the unconditioned attics common to split-levels near Tyler State Park.
- Disconnected returns in crawlspaces. Richboro’s humid summers promote mold and mildew growth in insulated flex duct, and the weight of saturated insulation can pull return ducts apart at joints. We repair, replace, and seal with materials rated for damp conditions.
- Supply registers leaking behind walls. In the older ranches, we often find that wall cavities were used as duct extensions without proper boots, so conditioned air leaks into wall studs before ever reaching your room. We install proper register boxes and seal the transition.
Pricing for Duct Sealing in Richboro, PA
Whole-house duct sealing in Richboro typically costs $450 – $850 for a single-system home with accessible ductwork. Larger homes, systems in finished attics or tight crawlspaces, or jobs requiring significant repair before sealing can reach $900 – $1,400. We do not price by the vent or room. You receive one flat price per system, agreed in writing before any work starts.
What moves the price: the linear footage of ductwork, accessibility (crawlspace work takes longer than an open basement), whether repairs are needed first, and the current leakage rate we measure during your free estimate. Homes in the Spring Mill area with longer runs and more complex branching often sit at the higher end of the range. The original ranches near Bustleton Pike tend toward the lower end, assuming accessible basements and straightforward trunk-and-branch layouts.
Every estimate is free, with no obligation. We’ll show you the pressure-test numbers, explain what we found, and write the price down before we touch anything. Call (361) 326-5060 to schedule.
