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.
Fast, Reliable Duct Sealing Across Camas
Duct sealing in Camas typically runs $450 – $950 for a whole-home system, with most jobs completed in a single visit and priced in writing before we start. We’re the Camas crew from Hollis Air Duct Cleaning, and we know the specific headaches this city’s housing stock throws at ductwork: the Gorge wind silt cycle, corroded mill-era galvanized plenums downtown, and shared dryer stacks in newer Lacamas Lake condos that can’t be fixed from one unit alone. Dispatch and scheduling are coordinated from our Seattle office, but our technicians live and work in this market. They know Prune Hill’s multi-zone custom builds, the parking constraints around the historic downtown core, and exactly how east-wind events change what “routine” duct maintenance looks like here. Call (361) 326-5060 for a free estimate, or read on for honest pricing and what we actually find when we open Camas duct systems.
Why Hollis Air Duct Cleaning Is Camas’s Preferred Duct Sealing Company
We’ve been part of the Garrison Partners family since 2004, and our Duct Sealing team serves Camas under The Garrison Standard: written price before work starts, arrive inside the quoted window, leave the site clean. That standard matters especially here, where duct access in older homes can mean tight crawl spaces and where condo associations need scheduling that respects residents.
Our technicians are background-checked and uniformed. You know who’s walking into your home before they arrive. Phones are answered by a live person 24 hours a day, 7 days a week, no voicemail loops. Every repair we perform in Camas is covered by our 365-Day Done Right Promise: if the work fails within a year, we return and make it right at no charge, including a free second visit. We don’t negotiate that; it’s written on every job.
We carry professional-grade equipment from Rotobrush, Nikro, and Guardsman, the same tools commercial crews use, and we stock sealing materials suited to both historic Camas galvanized systems and modern rigid ductwork. Our pricing is flat per system, agreed before we touch anything. No per-vent add-ons, no ballooning at the door.
Duct Repair in Camas
Duct Repair in Camas means fixing the physical damage that lets conditioned air escape into attics, crawl spaces, and wall cavities instead of reaching your rooms. In this market, we see two distinct failure patterns: original galvanized plenums in downtown mill-worker cottages that have corroded at the seams over a century of use, and flex duct in 1970s ranch homes near Lacamas Lake that has sagged, torn, or pulled loose from registers. A typical duct repair in Camas runs $280 – $650 depending on accessibility and material type, with most jobs priced after a camera inspection that we walk through with you on site.
Corroded Galvanized Plenums
The early-1900s cottages near Camas’s historic downtown core often have original supply trunks made of galvanized sheet metal. After decades of moisture cycling, the seams corrode and leak into wall cavities rather than into conditioned space. We cut out the failed section, fabricate a replacement from matching gauge metal, and seal with Guardsman mastic rated for the temperature swings these systems see.
Failed Flex Duct Connections
Camas ranch homes from the 1960s and 70s frequently used flex duct that degrades faster than rigid metal in our wet winters. The inner liner tears, the insulation gets waterlogged, and the connection to the register boot loosens. We replace the damaged run with properly supported flex or upgrade to rigid duct where access allows, then seal every joint with foil tape and mastic.
Air Duct Sealing in Camas
Air Duct Sealing in Camas addresses the gaps, cracks, and failed joints that pull unconditioned air into your system and blow heated or cooled air into places you don’t live. The Gorge wind makes this problem acute here: when east winds pressurize a home, they force fine volcanic silt through every leak point, and when the wind shifts, negative pressure pulls that silt deep into duct runs. A typical whole-home air duct sealing job in Camas costs $450 – $950, with larger custom builds in Prune Hill sometimes running higher due to multi-zone complexity. We price by the system, not by the vent, and we put that price in writing before any work begins.
Mastic and Foil Tape Sealing
For accessible ductwork in basements and crawl spaces, we brush on Guardsman duct sealing mastic, a water-based compound that remains flexible after curing, then reinforce high-stress joints with foil tape. This combination outlasts tape-only repairs by years, especially in Camas’s climate where temperature swings cause metal ductwork to expand and contract seasonally.
Aeroseal Injection for Inaccessible Runs
When ducts are buried in walls or sealed chases, as they often are in Lacamas Lake area custom homes, we use Aeroseal polymer injection. We pressurize the system, aerosolize the sealant, and let it bond to leak edges from the inside. The process is measured: we show you before-and-after leakage rates in CFM so you know exactly what changed.
Trusted Brands We Service in Camas
We carry sealing and filtration products from Guardsman, Honeywell, and Aprilaire, and our equipment roster includes Rotobrush rotary brush systems and Nikro negative-air machines. For Camas homeowners, this means we don’t order parts from a warehouse three states away and make you wait. We stock mastic rated for Pacific Northwest temperature cycling, foil tape with the adhesive backing that actually sticks in crawl space humidity, and replacement plenum sections sized for the smaller-diameter galvanized common in downtown Camas cottages. If your system needs a component we don’t have on the van, our Seattle office coordinates same-day or next-morning pickup. Fast turnaround matters when you’ve just watched gray silt blow from every register after an east-wind event.
Common Duct Sealing Problems We See in Camas Homes
- Corroded galvanized plenums in downtown mill cottages. The original supply trunks in homes near the historic core have seams that failed decades ago, leaking into wall cavities instead of living spaces. We find these with camera inspection and fabricate replacement sections on site.
- Shared dryer vent stacks in Lacamas Lake condos. A second-floor lint pathway can’t be sealed from one unit alone because pressure testing requires all stacked connections be verified together. We coordinate with building management and test the full stack.
- Zone damper leaks in Prune Hill multi-zone systems. Long, complex duct runs in custom builds make it easy to miss leaks at zone dampers and in unconditioned attic chases where Gorge wind-driven silt gets pulled in through failed seals.
- Attic chase pressurization from east-wind events. After strong Gorge winds, we find return ducts in Camas attics pulling visible gray silt through gaps around chase penetrations. Sealing these requires both mastic work and sometimes additional chase blocking.
Pricing for Duct Sealing in Camas, WA
Whole-home duct sealing in Camas typically costs $450 – $950. Smaller single-zone systems in downtown cottages usually fall at the lower end; multi-zone custom builds in Prune Hill with long attic runs and complex zone dampers run higher. Duct repair, when we can isolate a specific failed section rather than sealing the full system, runs $280 – $650.
What moves the price: accessibility (crawl space vs. finished basement), system size and zone count, material type (galvanized repair vs. standard sealing), and whether we need to coordinate multi-unit access for condo stacks. We do not price by the vent. We price by the system, flat, in writing, before any work starts. The number on the page is the number at the door.
Every estimate is free. We run a camera inspection, show you what we found, and give you a written price. No charge for the visit if you decide to wait. Call (361) 326-5060 to schedule.

FAQs About Duct Sealing in Camas
Camas sits directly in the Columbia River Gorge wind corridor, and after east-wind events ducts collect a visible layer of fine gray volcanic silt that isn’t typical of Portland or Vancouver suburbs. That silt accelerates seal degradation and indicates where air is leaking in or out. We time duct sealing to follow those wind episodes rather than a fixed annual schedule, so we catch the leaks while the evidence is fresh. Call (361) 326-5060 after your next east-wind event and we’ll inspect for free.
Yes, we regularly seal and repair galvanized systems in downtown Camas cottages, though the approach differs from modern rigid ductwork. We camera-inspect first to locate corrosion, fabricate replacement plenum sections from matching gauge metal where seams have failed, and seal with mastic rated for the temperature cycling these systems experience. The 365-Day Done Right Promise covers our repair work on these systems exactly as it does new construction. Call (361) 326-5060 to schedule a camera inspection.
Shared stacks must be pressure-tested and sealed as a complete system, not unit by unit, because a second-floor lint pathway can’t be sealed properly from one unit alone. For dryer vent issues, see our Dryer Vent Cleaning in Camas. We coordinate with your building management, test the full stack for leakage and backdraft, and seal connection points with fire-rated mastic and proper termination hoods. Every unit gets a written report of what was found and what was sealed. Call (361) 326-5060 and we’ll walk your property manager through the process.
In Camas, we recommend inspecting after major east-wind events rather than on a rigid annual schedule, because the Gorge wind cycle is the dominant factor that stresses duct seals here. A Prune Hill homeowner called us after a strong spring east-wind event left a gray silt film on every register in their multi-zone system. Our techs ran a camera inspection, found a 12-foot run of failed mastic at the air handler plenum, and sealed it with Guardsman mastic and foil tape before any source removal began. The homeowner reported the silt film didn’t return through the next wind cycle. Call (361) 326-5060 after your next wind event and we’ll check for new leaks.
Sealing comes first: a HEPA bypass filter or high-MERV media in a leaky duct system just pressurizes the leaks and pulls more unfiltered air from your attic or crawl space. We seal the ductwork, verify leakage reduction with a pressure test, then recommend filtration upgrades sized to your system’s actual airflow. For Camas homes dealing with Gorge wind silt, we often pair sealing with Honeywell or Aprilaire media filters rated MERV 11 – 13, which capture fine particulate without choking airflow in the systems common here. Call (361) 326-5060 and we’ll test your system and recommend the right combination.
