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 Repair & Sealing Across Greenwood Village
Duct repair and sealing in Greenwood Village typically costs $280-$850 for residential flex-duct repairs and $1,200-$3,500 for commercial duct board remediation, with most jobs scheduled within 3-5 business days. Our crews serve Greenwood Village from our Denver office, carrying compact agitation tools and portable HEPA filtration systems designed for the tight parking garages and HOA-restricted access that define work here. Call (720) 513-5159 for a written estimate before any work starts.
We’ve been in enough Greenwood Village homes to know the pattern: a 1980s two-story off Orchard Hills or a DTC-adjacent condo with a shared dryer vent stack, and a homeowner who has already had one “duct cleaning” that left the registers just as weak. Our Duct Repair & Sealing team documents every run with before-and-after photography, because vacuum noise without sealed joints is not repair.
Why CleanRun Air Duct Cleaning Aurora Is Greenwood Village’s Preferred Duct Repair & Sealing Company
Greenwood Village sits at a strange intersection: some of Colorado’s most expensive private homes share zip codes with dense corporate campuses along Arapahoe Road and Yosemite Street. We’ve worked both. Our crews know the HOA parking restrictions at DTC office towers and the access limitations of 1990s walkout ranches in the Orchard Hills and Belleview Estates areas. That dual experience matters when you’re deciding whether a contractor can handle your building’s specific constraints.
Our reputation here is built on documentation, not promises. Every job since 2013 has started with a written price and ended with a photo record of every duct run. Haven Standard Clause 1: no exceptions. Our technicians are background-checked, uniformed, and identified by name before arrival - Haven Standard Clause 3: Verified Crews. The 365-Day Done Right Promise is written on every invoice, not just stated in marketing copy.

Our Duct Repair & Sealing Services in Greenwood Village
Mastic Sealant Application
Mastic sealant is a water-based, fiber-reinforced compound brushed onto duct joints and seams to create a permanent, flexible air barrier - unlike foil tape, which dries and peels. In Greenwood Village’s 1980s-1990s housing stock, we apply mastic at trunk-to-branch connections where decades of thermal cycling have cracked original seals. The low humidity here accelerates tape adhesive failure, so mastic is the standard we apply on every residential repair. A typical mastic sealing job for a single system in Greenwood Village runs $280-$520.
Flex Duct Repair
Flex duct - the insulated, wire-helix tubing common in residential construction - sags, kinks, and separates at collars over time. In Greenwood Village’s Orchard Hills neighborhood and similar 1980s-1990s two-story developments, we regularly find original flex runs that have dropped from hangers and pulled apart at takeoff joints, so the system sucks attic air instead of delivering conditioned supply. Our field vignette: we were called to a 1980s two-story in Greenwood Village’s Orchard Hills area off Yosemite where the original flex-duct runs had sagged and popped apart at the trunk joints, so the second-floor registers barely moved air. Our tech ran camera inspection and found flex kinked near two takeoffs, then used mastic sealant and new collars to reseal the runs after negative-pressure source removal. When we pulled the dryer vent from the shared stack, the clogged lint pathway was the real culprit for the homeowner’s slow-drying complaints. Flex duct repair in Greenwood Village typically runs $340-$680 per run, depending on access and linear footage.
Metal Duct Repair
Metal ductwork - galvanized steel or aluminum - appears in older Greenwood Village commercial buildings and some high-end residential installs. We repair separated longitudinal seams, replace rusted sections, and seal with mastic or specialized metal-bonding compounds. Metal repairs near the DTC often involve rooftop or mezzanine air handlers where equipment access is restricted by parking garage clearances; our compact Rotobrush and Nikro portable systems reach these locations where truck-mounted units cannot.
Air Leak Repair
Air leak repair targets the pressure envelope of the duct system: plenum connections, register boots, and return air pathways where unconditioned attic or crawl space air enters the system. In Greenwood Village’s large 4,000-7,000 sq ft homes with 2-3 separate HVAC systems, leak repair often reveals that one system’s negative pressure is pulling return air through gaps in another system’s ductwork. We pressure-test, locate, and seal these crossover leaks. Air leak repair in Greenwood Village runs $450-$890 for residential systems.
Duct Insulation
Duct insulation replacement addresses degraded flex-duct outer jackets or uninsulated metal runs in unconditioned spaces. In Greenwood Village’s semi-arid climate, UV exposure in attic spaces degrades flex-duct vapor barriers faster than in humid regions where condensation is the primary failure mode. We replace with R-6 or R-8 insulated flex, sealed at every joint.

Our equipment roster includes Rotobrush brush-and-vac systems for residential flex-duct agitation, Nikro portable HEPA extractors for tight-access commercial work, and Honeywell media filters and electronic air cleaners that we install when duct repair reveals inadequate filtration upstream. We stock common repair components - flex-duct collars, mastic compounds, foil-faced insulation - so Greenwood Village jobs don’t wait on parts. Every brand we name is one you can look up independently; we don’t make performance claims beyond manufacturer specifications.
Common Duct Repair & Sealing Problems We See in Greenwood Village Homes
- Flex-duct sag and separation at takeoff collars. In 1980s-1990s Greenwood Village two-stories, original flex runs have lost hanger support and pulled apart at trunk connections. The system loses negative pressure and pulls 130°F attic air instead of conditioned supply. Camera inspection finds the gap; mastic and new collars fix it.
- Shared dryer vent stack lint accumulation. DTC-adjacent condos and apartment buildings in Greenwood Village often route dryer vents through a common stack. One unit’s lint accumulation backs up into neighboring units because the full lint pathway - not just the trap - is never scoped. Duct repair and sealing includes scoping the full stack length.
- Delaminating duct board in commercial air handlers. Many 1980s-era office tower HVAC units along Arapahoe Road and Yosemite Street still use internally-lined duct board that has begun to delaminate, releasing fiberglass fibers into occupied airspace. This triggers NADCA ACR remediation protocols and requires sealed containment during repair - a higher-liability, higher-ticket category than residential work.
- Equipment access restricted by HOA parking rules and tight DTC garages. Crews without compact agitation tools and portable HEPA filtration cannot reach rooftop or mezzanine air handlers to seal duct board joints properly. Our Nikro portable systems and Rotobrush compact units are specified for these constraints.

FAQs - Duct Repair & Sealing in Greenwood Village
Yes, most DTC-adjacent condos and office towers in Greenwood Village require written HOA or facilities approval before ductwork access, especially for shared mechanical rooms or rooftop air handlers. We provide a written scope of work, insurance certificate, and technician background verification - Haven Standard Clause 3 - for your property manager’s review. Call (720) 513-5159 and we’ll coordinate directly with your building’s facilities contact.
Yes, but only if the full stack is scoped and cleaned, not just your individual branch line. In Greenwood Village’s multi-unit buildings, we use camera inspection to locate lint accumulation points in the common stack, then perform source removal with negative-pressure containment so dislodged lint doesn’t enter neighboring units. The photo record shows you the full pathway. Call (720) 513-5159 to schedule a scope; estimates are free.
Greenwood Village’s 1980s-1990s housing stock near the DTC was built with original flex-duct systems now 30-40 years old, and the semi-arid climate accelerates seal degradation through thermal cycling without the moderating effect of humidity. Newer suburbs like Stonegate or parts of Centennial have 2000s-2010s construction with more intact ductwork. The age gap shows in our camera inspections: Greenwood Village homes routinely display sag, kink, and separation that we rarely find in 15-year-old systems.
Yes. Our crews are equipped for both: Rotobrush and Nikro portable systems for residential flex-duct work, and NADCA ACR containment protocols for commercial duct board remediation in DTC office towers. The same technician team does not alternate; we dispatch based on job category and equipment requirements. Both job types receive the written price, photo record, and 365-Day Done Right Promise.
Yes. At 5,700 feet in Colorado’s semi-arid high plains, Greenwood Village’s low humidity keeps fine particulates airborne and cycling through ductwork far longer than in humid climates where moisture settles dust. Annual cottonwood seed events in late May saturate outdoor air intakes, and Front Range wildfire smoke events (2020, 2021, and 2022 were particularly severe) deposit PM2.5 particles deep into duct systems that standard filter replacements cannot clear. Effective duct repair here must seal every leak point that would otherwise pull unfiltered attic or return air, and we often recommend upgrading to Honeywell media filtration as part of the repair scope. Call (720) 513-5159 to discuss filtration upgrades with your repair estimate.
