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.

Why Linden Air Duct Cleaning Is Redmond’s Preferred Air Duct Repair Company
We’ve been crawling under Eastside homes since 2004, and Redmond’s specific construction patterns are not a mystery to us. The 1985-2005 builder-grade homes that dominate neighborhoods like Education Hill, Bear Creek, and Willows/Rose Hill have nearly identical crawl-space flex duct systems, and we know what fails in them and when.
Marcus Veale leads our team, and the same standards apply on every Redmond job we take. Every technician is background-checked, identity-verified, and photo-badged under the Threshold Standard. Before the visit, you get the tech’s name and photo. At the door, they show a photo ID badge. No unmarked vans, no unnamed arrivals.
We also don’t play pricing games. The price goes in writing before work begins, every single time. If a covered repair fails within 365 days, we come back at no charge. That’s the Done Right Promise, and it’s on paper, not a verbal wink.
Air Duct Replacement in Redmond
Air Duct Replacement in Redmond means removing sections of damaged flex or rigid duct and installing new, properly supported runs. After a crawl-space flood or a leak that soaked the duct insulation, you’re often in replacement territory – not cleaning territory – because saturated fiberglass insulation loses its R-value permanently once soaked, so the section keeps condensing moisture even after the flood dries out.
When Flooded Ducts Need Replacement
A supply trunk that sat in standing water in a Redmond crawl space is usually a replacement. The inner liner holds water, mold establishes along the low points, and a surface cleaning inside the duct won’t fix what’s growing in the insulation jacket. If the duct was already sagging and poorly supported, the standing water collects even longer, and the damage compounds. We’ll show you camera footage before quoting a replacement.
Targeted Replacement vs. Full System
You don’t always need every run replaced. In a 1994 home off Education Hill, we pulled a flooded supply trunk after a burst supply line soaked the insulation. The camera inspection showed the inner liner was saturated past the point where source removal would help, so we replaced that run and left the unaffected returns in place. In a nearby Bear Creek townhome, the same storm intrusion only wetted the exterior jacket – we dried it, ran agitation tools, and HEPA-filtered the system under negative pressure, documenting each stage with photos. The adjuster could see exactly which duct sections were cleaned and which were replaced. That level of documentation matters in Redmond insurance claims.
Ductwork Repair in Redmond
Ductwork Repair in Redmond covers the more contained jobs: reconnecting a section that pulled apart, patching rodent-chewed holes, sealing leaky joints, re-supporting sagging flex runs, or replacing a crushed section under a beam. These repairs usually run $450 to $1,100 depending on the length and accessibility of the affected run.
Re-Supporting and Re-Sealing Crawl-Space Runs
Many Redmond homes from the 1990s have flex duct runs snaking through vented crawl spaces, sagging between supports and pulling apart at the seams. When a run sags below the grade of the trunk line, condensation pools at the low point all winter. We re-hang the duct with proper strapping, seal the joints with mastic, and then run a pressure test to confirm the system is tight.
Rodent Damage Repair
Redmond’s crawl spaces, especially in low-lying neighborhoods near the Sammamish River corridor, see mouse and rat pressure from fall through spring. Rodents chew through flex duct outer jackets and into the inner liner, leaving openings that pull crawl-space air straight into the supply. We cut out and replace the damaged section, then add physical barriers at the penetration points where we can.
Trusted Brands We Service in Redmond
We work on all standard residential duct systems, and we use professional-grade equipment from Nikro for agitation and negative-pressure extraction, with air-quality products from Honeywell and Aprilaire when repairs call for filtration or humidity upgrades. Because our crews are in Redmond every week, we typically have the common duct sizes and fittings on hand, which means many repairs are completed in a single visit.
Common Air Duct Repair Problems We See in Redmond Homes
- Sagging flex duct in vented crawl spaces. The original 1990s construction on Education Hill and Bear Creek used minimal strapping, and decades of gravity and moisture have pulled many runs down. The low points hold condensation, and in a flood they hold standing water.
- Black mold on the inner liner near the crawl-space vents. Redmond receives roughly 37 inches of rain a year, and the wet season keeps crawl spaces damp from October through May. The original venting strategy on many Education Hill homes pulls damp outside air directly across the flex duct runs all winter. What looks like homeowner neglect is often just how the houses were built.
- Saturated insulation on uninsulated runs. Once flood water soaks the fiberglass jacket on a crawl-space duct, that insulation is done. It holds moisture against the metal or inner liner, keeps condensing every winter, and becomes a mold source you can’t clean away.
- Rodent-chewed and disconnected sections. Rats and mice in Redmond crawl spaces chew through flex duct to get into the warm air stream. We routinely find sections that are disconnected entirely, dumping conditioned air into the crawl space while pulling damp, dirty air into the house. If this damage predated the flood and gets caught on a claim, an adjuster may deny it without camera photos showing the difference between chew marks and storm damage.
Pricing for Air Duct Repair in Redmond, WA
Targeted duct repair in Redmond, like re-sealing a disconnected joint or patching a small chew hole, typically runs $450 to $700. Replacing a 15-20 foot run of flooded flex duct with new insulated duct usually lands between $800 and $1,200, depending on crawl-space access and how much re-supporting is needed. A full replacement of all accessible crawl-space supply runs in a 2,000 square foot Education Hill home runs $1,600 to $3,200. The price is per system, agreed in writing before any work begins, not per vent and not open-ended. Call (980) 447-2498 for an exact quote – our estimates are free.

FAQs About Air Duct Repair in Redmond
It depends on whether water reached the insulation or structural parts of the duct. If the inner liner and exterior jacket are both saturated, the insulation loses its R-value and will keep condensing moisture indefinitely. Cleaning the inner surfaces won’t stop that. If only the exterior jacket got wet and the interior stayed dry, we can often dry it, run agitation tools, and HEPA-filter the system under negative pressure. We’ll confirm this with camera inspection before quoting, and we’ll show you the footage. Call (980) 447-2498 and we’ll walk through the decision with your specific situation.
We photograph and record all repair work with a camera scope before, during, and after the job. Each duct section is labeled, and the report shows exactly which sections were cleaned, which were dried, and which were replaced. The goal is to give your adjuster a clear, itemized record that supports the claim. If the damage existed before the water event – like rodent chews that predate the flood – we’ll document that separately so the claim reflects what actually happened.
The 1990s homes on Education Hill share nearly identical builder layouts with long, low-slope flex duct runs in vented crawl spaces. The original venting strategy pulls damp marine air directly across those ducts all winter. When the liner is already compromised from age and sagging, condensation forms at the low points and mold follows. It’s a structural pattern of the neighborhood’s construction, not a maintenance failure on your part. Replacing the affected runs and re-supporting them properly usually ends the cycle.
Any duct replacement we install in Redmond is sealed to current energy code, using mastic at joints and proper strapping at support intervals. Flex duct is sized for airflow, not just whatever fits, and we pressure-test the system after the work. You don’t need to know the code specifics; you just need a contractor who builds it to current standard rather than copying the original, under-supported 1990s install.
Yes. Rodent damage shows up as clean, sharp chew marks around the edges, usually with nesting material or droppings nearby. Flood damage leaves waterlines, saturated insulation, and streaking on the inner liner. The distinction matters because insurance policies often cover one and not the other. We document both during the inspection, and we’ll tell you honestly which one you’re dealing with. Call (980) 447-2498 for an inspection and a written price before anything starts.
If you have water-damaged ductwork in your Redmond home, you need a real inspection, not a phone quote. Call (980) 447-2498 and a live person answers, any time, day or night. We’ll set up a time, send you the tech’s name and photo before the visit, and give you a written price for exactly what’s needed. No bait pricing, no open-ended invoices – just straight answers about what your ducts need.
