We’re familiar with the specific problems Camas homes face: the mill particulate from WestRock, the wildfire smoke that pours through the Columbia River Gorge each August and September, and the split housing stock that ranges from 1920s mill-worker bungalows to tight 2000s construction around Lacamas Lake. Our technicians make the drive from Portland-Vancouver regularly, and we can usually be at your door in Camas within 24 hours of your call.

Our Duct Repair & Sealing Services in Camas
Mastic Sealant Application
Mastic sealant is the backbone of most duct sealing work we do in Camas, especially in homes within a mile or two of the WestRock mill. The acidic compounds in mill particulate degrade standard tape adhesives faster here than in Vancouver or Washougal, so we brush on professional-grade mastic at every joint, seam, and register boot. A typical mastic sealing job for a Camas home runs $280-$450 for a partial system, or $550-$850 for full trunk-and-branch sealing. We use Nikro and Abatement Technologies equipment to pressurize the system and verify seal integrity before we leave.
Flex Duct Repair
Flex duct is common in Camas additions and 2000s tract homes near Lacamas Lake, and it’s where we see some of the most localized failures. The wildfire smoke particulates that blow through the Gorge each summer bake onto mastic and tape, reducing adhesion. Then winter humidity swells the insulation jacket. We recently sealed a 1950s bungalow on Adams Street where the original metal ducts had rusted through from years of mill-moisture and paper dust. Our crew applied mastic sealant and replaced two flex duct runs with Rotobrush equipment, restoring system pressure and eliminating the sulfur smell. Flex duct repair in Camas typically costs $180-$340 per run, including materials and labor.
Metal Duct Repair
Original metal ductwork in Camas’s older homes - the bungalows and craftsmans near downtown, many built for Georgia-Pacific mill workers - corrodes faster than you’d expect. The sulfur compounds from WestRock emissions accelerate rust at seams and pinhole leaks, particularly in attics with poor ventilation. We patch small sections with matching gauge metal and seal with mastic, or replace runs when corrosion is too advanced. Metal duct repair in Camas runs $220-$480 for spot work, or $650-$1,200 if we’re replacing a major trunk line. We’ll show you the camera footage and tell you straight whether repair or replacement makes sense for your system.
Duct Insulation
Duct insulation in Camas serves two purposes: keeping heated air warm as it crosses unconditioned attic space, and preventing condensation that leads to mold. The wet, mild winters here mean attics stay damp for months, especially in the tightly-sealed 2000s homes around Lacamas Lake where moisture has nowhere to escape. We install foil-faced fiberglass or closed-cell insulation wraps, sealed at every seam with mastic. Duct insulation work in Camas typically runs $320-$580 for a partial system, or $700-$1,100 for full replacement of degraded wraps.

Trusted Brands We Service in Camas
We carry parts and materials from Honeywell, Aprilaire, and Abatement Technologies - the same brands serious HVAC contractors specify, not the discount hardware-store stock that fails in a season. For Camas customers, this means faster turnaround. We don’t wait a week for a specialty fitting to ship from out of state. Our trucks are stocked for the specific duct configurations common in Clark County, from the spiral metal of pre-war homes to the flex-and-board systems in newer construction.
Common Duct Repair & Sealing Problems We See in Camas Homes
- Flex duct joints loosen after wildfire season. The fine particulate from Gorge-blown smoke coats mastic and tape, then summer heat bakes it brittle. By October, joints separate and airflow drops. We see this most in homes off Northeast 3rd Avenue and the Lacamas Lake hills.
- Metal duct seams corrode near the mill. WestRock’s sulfur compounds accelerate rust in attics within a mile or two of the facility. Pinhole leaks spray conditioned air into unused attic space and draw in that faint sulfurous odor.
- Insulation wrap collapses in 2000s tract homes. Tight construction around Lacamas Lake traps humidity; smoke-laden filters restrict airflow and extend run times, saturating the insulation jacket until it sags and tears.
- Register boots pull away from drywall. Seasonal expansion and contraction in Camas’s older homes - the bungalows with plaster and lath - cracks mastic at the register connection. Cold air spills into wall cavities instead of living spaces.

FAQs - Duct Repair & Sealing in Camas
The mill’s sulfur compounds and wood-pulp particulates settle into residential HVAC systems across Camas in ways that don’t apply to neighboring cities. Ductwork in west-side homes often carries a distinctive particulate load that accelerates corrosion, degrades sealants, and produces a faint sulfurous odor at the registers. We factor this into our material selection and sealing protocol - standard tape adhesives fail faster here, so we specify mastic rated for acidic environments. Call (844) 685-6342 if you’re noticing unusual odors or rapid filter clogging.
Repair is usually viable if corrosion is localized to seams or short runs; replacement makes sense when the trunk line is perforated with pinholes or the original 1950s galvanized steel is thinning structurally. A typical repair on a Camas bungalow runs $220-$480, while full trunk replacement starts around $650. We’ll show you the camera footage and give you straight guidance - no pressure to replace what can be sealed. Call (844) 685-6342 for a free inspection.
Smoke particulates from Eastern Washington and Oregon wildfires coat duct surfaces with fine, oily residue that reduces mastic and tape adhesion. Then fall humidity swells the substrate, and by winter the seal has cracked. We see this pattern every year in Camas, particularly in homes that ran continuous HVAC through August and September with windows sealed. Our solution is thorough cleaning before resealing, then mastic rated for contaminated surfaces. Call (844) 685-6342 to schedule post-smoke-season inspection.
Yes - proper insulation prevents warm, moist air from contacting cold duct surfaces and condensing. In Camas’s wet winters, uninsulated or degraded wraps in attic runs create persistent moisture that breeds mold and corrodes metal. New insulation with intact vapor barrier, sealed at every seam with mastic, eliminates this. Duct insulation in Camas typically runs $320-$580 for partial work. Call (844) 685-6342 for an assessment of your attic ductwork.
Newer homes, particularly the 2000s-2010s construction around Lacamas Lake, have tighter envelopes that trap particulates and moisture, making duct sealing more critical for air quality. Older homes near downtown have leakier construction but original metal ductwork that’s often corroded by decades of mill exposure. The repair approach differs: newer homes need precision sealing to manage pressure and filtration; older homes often need metal repair plus sealing. We assess each system individually. Call (844) 685-6342 to discuss your home’s specific needs.
