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 Orchards
Duct sealing in Orchards typically runs $450 – $1,200 for a whole-system seal on an average single-family home, with most jobs completed in a single visit. We’re the Duct Sealing team at Hollis Air Duct Cleaning, and we serve Orchards from our Seattle dispatch office with crews that know Clark County’s housing stock inside and out.

HVAC Duct Sealing in Orchards
HVAC Duct Sealing in Orchards means finding the gaps, cracks, and failed connections in your forced-air system and closing them with mastic and mesh so the air you paid to heat or cool actually reaches your rooms. In Orchards, we see this problem most often in homes built between 1970 and 1995, where original foil tape at trunk-to-branch collars has dried and lifted after decades of damp Clark County winters. The conditioned air leaks into your crawlspace. Your furnace runs longer. Your filter loads up with crawlspace dust.
A typical HVAC duct sealing job in Orchards runs $450 – $1,200 depending on system size, crawlspace access, and how many collars need reworking. We inspect with a camera first, quote in writing, then seal with professional-grade mastic rated for the temperature swings these systems see.
Camera Inspection Before We Quote
We run a scope through your trunk line and branch runs before we touch a tool. In Orchards, this often reveals crushed flex duct under low-clearance crawlspaces or collars that have been leaking for fifteen years. You see the footage. We explain what it means for your airflow and your energy bill. Then we write the price down.
Mastic and Mesh, Not Tape
We don’t use foil tape for sealing. We use water-based duct mastic reinforced with fiberglass mesh, applied to cleaned metal surfaces. It stays flexible, it doesn’t dry out, and it’s rated for the temperature cycling your Orchards furnace puts it through. This is the same approach commercial crews use, and it’s what The Garrison Standard requires on every job.
Duct Repair in Orchards
Duct Repair in Orchards addresses the physical damage we find once we get eyes inside the system: disconnected collars, crushed flex runs, rusted trunk sections, and rodent damage in crawlspaces that draw outdoor air. Sealing alone won’t fix a duct that’s been crushed by a previous contractor crawling over it or chewed through by rodents attracted to the warmth.
Repair costs in Orchards typically fall between $300 and $900 for collar reconnection, flex replacement, or trunk patching, with full section replacement running higher if the damage is extensive. We always inspect first, show you what we found, and separate repair from sealing so you understand where your money is going.
Reconnecting Disconnected Trunks
We find this more often than you’d expect. A main trunk collar slips off the air handler plenum, sometimes for years, and the homeowner only notices because one room won’t heat or the furnace runs constantly. We reconnect with mechanical fasteners and seal with mastic. No shortcuts.
Replacing Crushed Flex Runs
Low-clearance crawlspaces in Orchards’ older subdivisions mean flex duct gets kinked during other trades’ work or simply collapses over time. We replace with properly sized flex, support it to prevent sagging, and seal both ends. Airflow restored. Cold spots gone.
Trusted Brands We Service in Orchards
Our equipment roster includes Rotobrush rotary brush systems for source removal, Nikro negative-air machines for containment during cleaning, and filtration products from Aprilaire and Abatement Technologies. We stock common collar sizes, flex diameters, and mastic supplies so Orchards customers aren’t waiting on parts. For homes with integrated air cleaners, we can source Guardsman and Honeywell filtration upgrades while we’re sealing the ductwork. Everything is professional-grade, not hardware-store gear, and we explain what each piece does for your specific system before we start.
Common Duct Sealing Problems We See in Orchards Homes
- Failed foil tape at trunk-to-branch collars. Orchards’ 1970s – 1990s tract houses were built with bare sheet-metal trunk lines and flex branches taped at the collar. After decades of Clark County’s damp winters, that tape has dried and lifted, leaving return-side leaks that pull crawlspace air straight into the furnace. This repair pattern is far more common here than in Portland’s tighter, newer eastside infill.
- Crushed or kinked flex duct in low-clearance crawlspaces. The older subdivision stock in Orchards often has 18 to 24 inches of clearance, and decades of plumbing, electrical, and pest-control work have left flex runs flattened or pinched. Sealing at the register end does nothing if the run itself is collapsed.
- Return-side leaks drawing outdoor allergens and moisture. Many Orchards homes have return plenums or trunk sections in unconditioned crawlspaces. When these leak, they don’t just lose efficiency; they actively pull in rodent debris, mold spores, and damp Pacific Northwest air. Sealing supply ducts only leaves this problem untouched.
- Disconnected main trunk collars behind the air handler. We ran a camera inspection on a 1988 split-level off NE 112th Ave near the Orchards Fred Meyer and found the main trunk collar disconnected behind the air handler, with crushed flex branch runs under the low-clearance crawlspace. We did source removal with negative pressure and HEPA filtration, reconnected the collar, and sealed the whole system with mastic and mesh before rebalancing registers. The homeowner said the cold spots in the back bedroom and the dust film on the furnace filter dropped off within the first heating season.

FAQs About Duct Sealing in Orchards
Orchards’ 1970s – 1990s houses were built with foil-taped collars and flex branches in unconditioned crawlspaces, and that tape fails predictably after 30-plus years of damp winters. Newer Vancouver construction uses tighter duct systems, often in conditioned space, with sealed mechanical connections instead of tape. The older stock here simply reached failure age all at once. Call (361) 326-5060 and we’ll show you what your system looks like inside.
Yes. We work in 18-inch clearance regularly, and our technicians carry the right gear to reach, inspect, and seal in tight Orchards crawlspaces. If a run is too damaged to seal, we’ll tell you and quote replacement separately. Camera inspection first means no surprises.
Very likely. Cleaning removes buildup but doesn’t stop new dust from entering through leaks on the return side. In Orchards, we often find return leaks pulling crawlspace air straight past the filter. Seal those leaks, and the dust source disappears. Call (361) 326-5060 for a camera inspection that shows exactly where your system is drawing from.
Yes. Clark County’s wet winters keep crawlspaces humid year-round, which accelerates tape failure, promotes mold growth on leaking return surfaces, and draws moisture into the air handler through unsealed joints. Sealing cuts off those moisture pathways and reduces the load on your system. The longer you wait, the more conditioned air you’re heating or cooling for your crawlspace instead of your rooms.
We use Rotobrush rotary systems for pre-seal cleaning, Nikro negative-air machines for containment, and seal with professional-grade mastic and mesh. For filtration upgrades, we stock Aprilaire and Abatement Technologies products, plus Guardsman and Honeywell options for integrated systems. Everything is explained before we start, and the work is covered by our 365-Day Done Right Promise. Call (361) 326-5060 for details on your specific system.
