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.

AfterAir Duct Cleaning in Gresham, OR
Dryer vent cleaning in Gresham costs $120-$195 and runs on a different clock than the rest of the metro. The city’s 1970s and 1980s tract homes push laundry exhaust through long, low-clearance crawl-space runs, and in the Rockwood corridor especially we find sagging flex vent that traps lint, moisture, and the occasional rodent nest. That combination turns what should be a simple thirty-minute service into something closer to a surgical job. Call (806) 606-6902 when you want a look inside before anyone touches a bolt.
Most Gresham homeowners start with one question: is the problem my ducts, my dryer, or my vent run? We answer it with a camera, not a guess. Every CleanRun visit includes a documented photo record of the inside of every duct run, before and after, delivered to you as part of the standard job record. If you’re looking for air duct cleaning specifically, that service has its own Air Duct Cleaning in Gresham page. The HVAC side lives on our HVAC Cleaning in Gresham page. What follows here covers the three services that complete the picture: dryer vent cleaning, duct repair and sealing, and air quality and sanitizing.
Why Gresham Homes Are Different
Gresham sits against the Cascade foothills and catches more rain than Portland proper. Orographic moisture lift is real and consistent here; annual rainfall exceeds the westside by several inches, and the Columbia River Gorge keeps funneling damp air directly into the city. That moisture matters because Gresham’s dominant housing stock, the ranch and split-level tract homes built between the mid-1970s and early 1990s, routes most supply ducts through crawl spaces that were never insulated well and rarely stay dry. Sheet metal and early flex duct from that era has now gone 30 to 40 years without a cleaning.
The Rockwood neighborhood deserves a mention of its own. Many 1980s homes there have flex duct installed without adequate hangers. Over decades, that duct sags into low spots, and those belly sections collect standing moisture and compacted debris. We pull the same thing out of nearly every Rockwood job: wet lint, mold-darkened insulation, and dirt so dense the airflow has been fighting it for years. Newer construction elsewhere in the metro rarely shows this pattern. In Gresham, mold-laden ductwork is a more common finding than a dust-only problem, and we treat it accordingly.
Our Main Gresham Services
Two service lines carry most of the call volume from Gresham homeowners, and both have their own dedicated pages with full pricing and local detail.
Air Duct Cleaning in Gresham
Our Air Duct Cleaning in Gresham page covers the full system, from return registers to supply plenum, with Rotobrush and Nikro negative-pressure extraction equipment. Gresham’s crawl-space supply runs pick up ground moisture, pest debris, and decades of construction dust from the building boom. The page breaks down pricing, what the camera shows, and how long a typical ranch-style home takes.
HVAC Cleaning in Gresham
The HVAC Cleaning in Gresham page addresses the mechanical side: blower wheels, evaporator coils, condensate pans, and air handler housings. Homes built in the 1980s often run original equipment or early replacements, and Gresham’s humidity means coil growth is common. We explain what gets cleaned, what it costs, and when coil cleaning alone solves the problem without a full duct job.

BeforeAfterDryer Vent Cleaning in Gresham
Dryer vent cleaning in Gresham starts with a camera inspection of the full run, because the most common failure here is structural, not lint-related. Older flex vent in Rockwood and other 1980s tracts sags between supports, and every sag becomes a lint dam. Add in Gresham’s extra precipitation and crawl-space humidity, and those dams hold moisture against the lint until the restriction is severe enough that a dryer starts tripping its high-limit switch. The service solves a fire risk and a drying-time problem at once, and our full process is documented on the Dryer Vent Cleaning page.
Dryer Vent Inspection
Signs you need it
Clothes take two cycles to dry, the laundry room gets humid during a cycle, or you notice a burning smell when the dryer runs for more than ten minutes.
What it costs in Gresham
A camera-only dryer vent inspection in Gresham runs $85-$140, and the price is rolled into the cleaning if you proceed the same day.
How we do it
We disconnect the vent from the dryer, run a high-resolution camera from the appliance side to the exterior termination, and show you every restriction, sag, and gap on the screen before quoting any repair.
Lint Removal
Signs you need it
Visible lint blows out the exterior vent hood, the dryer runs hotter than normal, or the exterior flapper doesn’t open fully during a cycle.
What it costs in Gresham
Full lint removal from a standard Gresham single-story vent run costs $120-$195, with the final price written before work starts under Haven Standard Clause 1.
How we do it
We run a rotating brush from the exterior termination inward, then follow with a high-pressure negative air sweep to pull loosened lint out of the run rather than lodging it deeper in the low spots.
What Dryer Vent Cleaning Costs in Gresham
| Item | Typical range in Gresham |
|---|---|
| Camera inspection only | $85-$140 |
| Full lint removal (standard single-story run) | $120-$195 |
| Bird guard installation with vent | $90-$160 |
Why do dryer vents clog faster in Gresham than in westside suburbs?
Gresham’s crawl-space duct runs are uninsulated more often, and the extra rain means more ambient moisture. Lint that would blow free in a dry, rigid run instead sticks to damp flex-duct walls, building up in the sagging belly sections common in Rockwood-era construction. Call (806) 606-6902 for an exact quote; estimates are free.
Can you clean a dryer vent that runs through a crawl space?
Yes, and that describes most of Gresham. We access the crawl-space run from the exterior vent and the appliance side, using the camera to confirm every section is clear. The photo record shows it before and after. Call (806) 606-6902 for an exact quote; estimates are free.
Duct Repair & Sealing in Gresham
Duct repair and sealing in Gresham usually means one of two jobs: replacing sagging flex duct in crawl spaces, or sealing leaky sheet-metal joints that have been losing conditioned air into unconditioned space since the Reagan administration. Older Gresham homes, particularly the mid-1970s through early 1990s tract stock, run supply ducts through crawl spaces where ground moisture and pest traffic have done real damage. The fix is a physical repair, not a cleaning, and the full scope is on our Duct Repair & Sealing page.
Flex Duct Repair
Signs you need it
Rooms at the end of a supply run stay cold in winter, your crawl space smells musty, or an energy audit already flagged restricted airflow in the duct system.
What it costs in Gresham
Replacing a sagging or collapsed flex-duct section in Gresham runs $145-$290 per run, depending on access and length.
How we do it
We cut out the failed section, rehang the replacement flex with proper support straps, and seal both connections with mastic before insulating to match the original spec.
Mastic Sealant
Signs you need it
You can feel air moving near duct joints in the crawl space, dust accumulates unusually fast around registers, or the system seems to run constantly without changing room temperature.
What it costs in Gresham
Sealing accessible duct joints with mastic across a standard Gresham single-story home runs $250-$500, with the price set by the number of accessible joints.
How we do it
We brush mastic sealant over every accessible joint and seam from air handler to termination, then take a photo of each sealed section for your documented record.
What Duct Repair & Sealing Costs in Gresham
| Item | Typical range in Gresham |
|---|---|
| Flex duct section replacement | $145-$290 per run |
| Mastic sealing of accessible joints | $250-$500 |
| Duct insulation replacement per section | $120-$230 |
Is duct sealing worth doing in a 1980s crawl-space home?
Yes, and it’s usually the highest-return fix in Gresham. Leaky sheet-metal joints lose 20 to 30 percent of conditioned air into the crawl space, which is particularly costly here given the moisture and cold air. Call (806) 606-6902 for an exact quote; estimates are free.
How do I know the work was actually done if the ducts are in the crawl space?
You get a documented photo record of every sealed joint and replaced section, inside the run, before and after. That’s a standard CleanRun deliverable on every job, not an optional add-on. Call (806) 606-6902 for an exact quote; estimates are free.
Air Quality & Sanitizing in Gresham
Air quality and sanitizing in Gresham addresses what grows in ducts after decades of Cascade foothill moisture. The same crawl-space duct runs that leak air and collect debris also become the warm, damp passageway that carries mold spores and bacteria into every room. Gresham homes with original 1980s flex duct are the worst candidates for microbial growth, because the inner liner is often compromised and the sagging sections hold standing water. Our full scope is documented on the Air Quality & Sanitizing page.
Mold Treatment
Signs you need it
Musty odor that worsens when the system runs, visible dark staining around registers, or a respiratory pattern that improves when you leave the house.
What it costs in Gresham
Whole-system microbial treatment for a standard Gresham single-story home runs $325-$550, including sanitizer application through the full duct network.
How we do it
After cleaning the affected runs, we fog an EPA-registered antimicrobial through the supply and return sides, then run the blower to distribute it across coil, plenum, and every branch.
Odor Removal
Signs you need it
Persistent cooking, pet, or cigarette odor lingers after surfaces are cleaned, or a stale smell rises from the vents every time the heat kicks on.
What it costs in Gresham
Odor removal in Gresham duct systems runs $180-$315, depending on whether we’re treating the source inside the ductwork or the whole home.
How we do it
We locate the odor source with the camera, remove the material if it’s debris, and treat the duct surfaces with a commercial-grade vapor system that leaves no masking fragrance.
What Air Quality & Sanitizing Costs in Gresham
| Item | Typical range in Gresham |
|---|---|
| Whole-system mold treatment | $325-$550 |
| Odor removal (duct system) | $180-$315 |
| UV light installation with lamp | $220-$430 |
Does Gresham’s humidity actually cause mold in ducts?
Yes, more consistently than in drier westside suburbs. The Cascade foothills add several inches of rain annually, and the Gorge funnels damp air through the city, so crawl-space duct runs hold moisture and support microbial growth. Call (806) 606-6902 for an exact quote; estimates are free.
Can sanitizing fix the musty smell without duct replacement?
Often yes, if the duct liner is still intact. We treat the surface growth and document the result with photos. If the flex liner is torn or water-damaged, replacement is the honest fix. Call (806) 606-6902 for an exact quote; estimates are free.

What pushes a Gresham job toward the top of these ranges is almost always access: crawl-space runs with low clearance, duct sections above finished ceilings, or rectifying repairs left by previous handymen. The second factor is length of run; a ranch homes with returns at the far end costs more than a compact split-level with short branches. Every CleanRun price is written before any work starts, under Haven Standard Clause 1, and no job proceeds on a verbal number.
