What Our Duct Repair & Sealing Service Includes
Duct Sealing
Duct sealing closes the gaps, cracks, and disconnected joints that leak conditioned air into your attic, crawl space, or wall cavities. In Vancouver’s climate — where wet winters and summer heat waves push HVAC systems hard — even 15% duct leakage can add $300–$500 to annual energy bills. We use professional-grade mastic sealant and metal-backed tape rated for temperature cycling, then verify our work with a pressure differential test so you know the seal holds.
Flex Duct Repair
Flex duct is common in Vancouver homes built from the 1980s through the 2000s, but the plastic liner degrades, the insulation compresses, and the wire coil can get crushed during roofing or pest activity. We replace damaged flex runs with properly sized, insulated duct that matches your system’s CFM requirements, and we suspend it correctly so it doesn’t sag or kink. Eric Bailey has replaced flex duct in hundreds of Vancouver-area homes, including many in Salmon Creek and Orchards where original builder-grade flex is reaching end of life.
Metal Duct Repair
Galvanized steel ductwork in older Vancouver homes — common in neighborhoods like Minnehaha and Kenton — can rust at seams, separate at joints, or rattle loose from vibration. We reseal metal duct with mastic and mechanical fasteners, patch corroded sections with matching gauge steel, and reinforce weak hangers. Our Rotobrush extraction system cleans the interior before we seal, so we’re not trapping construction dust or mold spores inside a freshly repaired system.
Duct Insulation
Uninsulated or degraded duct insulation in attics and crawl spaces wastes energy and creates condensation problems during Vancouver’s humid seasons. We install fiberglass duct wrap or closed-cell insulation at R-values appropriate for our Pacific Northwest climate zone, sealed with vapor barriers to prevent moisture accumulation. Proper insulation also reduces the temperature swing that causes duct metal to expand and contract — a common source of the “pinging” noise many Vancouver homeowners hear at startup.
Mastic Sealant
Mastic is a water-based, fiber-reinforced compound that we brush or spray onto duct seams — it cures into a flexible, permanent seal that outlasts foil tape by decades. Unlike duct tape (which fails within months on heated surfaces), mastic maintains its bond through Vancouver’s freeze-thaw cycles and the thermal stress of daily HVAC operation. We apply mastic to every accessible joint, takeoff, and register boot, then label the repair date for future service reference.
Air Leak Repair
Air leaks are the silent efficiency killer: they pull unconditioned attic air into your supply ducts, or dump heated air into your crawl space. We locate leaks using smoke pencils and digital manometers, then repair them at the source rather than masking symptoms with higher thermostat settings. In homes near Vancouver’s I-205 corridor and Five Corners, we’ve found that post-1980s construction with attic ductwork often leaks 20–30% of total airflow — money you’re literally blowing into unused spaces.

Brands We Service for Duct Repair & Sealing
We’ve worked extensively with Aprilaire whole-home air quality systems, including their zoning dampers and fresh air intakes that integrate directly with ductwork. When we repair ducts in homes with Aprilaire components, we verify that damper actuators still open and close fully after sealing — a step many duct cleaners skip that leaves your zoning system unbalanced.
Our Abatement Technologies equipment comes into play when duct damage has allowed moisture intrusion and microbial growth. We can contain, clean, and seal contaminated duct sections to Duct Repair & Sealing in Vancouver standards that basic duct tape repairs simply don’t meet. Whether your system uses Aprilaire, Abatement-compatible components, or any other make, we can assess, repair, and verify the integrity of your complete duct network.
Signs You Need Duct Repair & Sealing Right Now
- Uneven heating or cooling between rooms. If your master bedroom in Vancouver’s Lake Shore area stays frigid while the living room overheats, you likely have a disconnected or crushed duct run. We map airflow at each register with a digital anemometer to pinpoint exactly which branch is compromised, rather than guessing.
- Dust blowing from vents right after cleaning. Persistent dust shortly after professional cleaning usually means your return duct has a leak in an attic or crawl space, pulling in fiberglass particles, rodent debris, or old insulation. We inspect the full return path with a borescope camera to find the breach.
- Energy bills climbing without rate increases. Clark Public Utilities customers in Vancouver have seen stable rates, so a 20%+ bill increase often traces to duct leakage forcing your heat pump or furnace to run longer. Our pressure testing quantifies the leakage before we quote any repair.
- Whistling, rattling, or whooshing sounds from ducts. These noises indicate high-velocity air escaping through gaps, or loose duct sections vibrating against framing. In Barberton and North Portland homes we’ve serviced, whistling at register boots almost always reveals a gap between the duct and the floor/wall penetration that mastic sealing resolves permanently.
- Musty smells when the HVAC cycles on. Odors mean moisture is entering through duct leaks and supporting microbial growth in your ductwork or the surrounding insulation. This is where our Abatement Technologies containment protocols matter — we don’t just seal over the problem, we address the contamination source first.
Our Duct Repair & Sealing Process — Step by Step
- 1
System inspection and airflow mapping. Eric Bailey arrives with a digital manometer, thermal camera, and borescope to assess your entire duct network. We measure static pressure, check temperature differentials at each register, and photograph any visible damage — you’ll see exactly what we see before any work begins.
- 2
Leak detection and damage documentation. We pressurize the duct system and use smoke pencils or theatrical fog to make leaks visible. Every breach is photographed and mapped to a floor plan so you understand which repairs address which symptoms. This documentation also becomes your baseline for future comparison.
- 3
Cleaning before sealing. Using our Rotobrush or Nikro extraction system, we clean the interior surfaces that will receive mastic or new insulation. Sealing dirty ducts traps debris permanently — we don’t cut this corner, even when it adds time to the job.
- 4
Repair and seal with professional-grade materials. We replace damaged flex or metal sections, apply mastic to all seams, install proper insulation, and mechanically secure every joint. For homes in Vancouver’s older neighborhoods like Hazel Dell, we often find and correct multiple generations of “good enough” repairs that previous owners or handymen applied.
- 5
Verification testing and report. We retest static pressure and airflow after sealing, then provide a written summary with before/after measurements and photos. If we don’t achieve measurable improvement, we keep working until we do — that’s the accountability built into owner-operated service.
How Much Does Duct Repair & Sealing Cost in Vancouver?
A typical single register boot reseal in Vancouver runs $180–$260. Partial system sealing with mastic for a 1,500-square-foot home generally falls between $450 and $750. Whole-system flex duct replacement, including insulation and proper suspension, ranges from $800 to $1,200 depending on linear footage and attic accessibility. Metal duct repair with patching and resealing typically costs $350–$650 for localized work, or $900–$1,400 if multiple trunk lines need attention.
Several factors move the price: attic vs. crawl space access (crawl spaces in Vancouver’s flood-prone areas like Duct Repair & Sealing in Hazel Dell often require additional safety prep), the age and condition of existing materials, and whether we discover disconnected returns or pest damage during inspection. Homes in Minnehaha and Duct Repair & Sealing in Minnehaha with original 1960s metal duct often need more extensive joint reinforcement than newer construction.
To avoid overpaying, get a written estimate that specifies exactly which duct runs will be sealed or replaced, what materials will be used, and how results will be verified. Our estimates are free and itemized — no lump-sum mystery pricing. Call (833) 637-3677 and we’ll measure your system before quoting.
