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 runs $400-$1,200 per system for most homes, with multi-zone properties often requiring separate scope and pricing for each air handler. Our crews are dispatched from our Denver office and carry the equipment to seal metal seams, re-support sagging flex duct, and replace delaminated fiberboard trunk lines on the same visit. If your home has three or more zones, we’ll price each system separately so you know exactly what each one costs before we open a single panel. Call (720) 315-7291 for a written estimate.
Why CleanRun Air Duct Cleaning Littleton Is Greenwood Village’s Preferred Duct Repair & Sealing Company
We’ve worked in the DTC-corridor subdivisions along East Orchard Road and Belleview since 2013, and the pattern is consistent: large executive homes with complex multi-zone systems that need more than a quick seal-and-go. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and we publish our license number on every page so you can verify it with the state.
Greenwood Village homeowners have left us detailed reviews mentioning the photo records we deliver, the written prices they received before work started, and the 365-Day Done Right Promise that backs every job in writing. We don’t chase coupon customers. We answer calls with a live person, schedule deliberately, and show up with Rotobrush and Nikro equipment that you can look up before we arrive.
Because our Denver office coordinates dispatch across the metro, response time to Greenwood Village is typically 24-48 hours for non-urgent sealing and repair work. We know which neighborhoods have the 1980s flex duct with hanger problems and which have the delaminating fiberboard trunks from the same era. That local knowledge changes what we pack on the truck and how we scope the job.
Our Duct Repair & Sealing Services in Greenwood Village
Duct Sealing
Sealing in Greenwood Village usually means addressing conditioned air leaking into unconditioned attics and crawl spaces before it ever reaches a register. We use mastic sealant on plenum and boot connections, not tape that dries and fails. In a typical 3,500 sq ft home off Belleview with three zones, we’ll seal the supply and return connections at each air handler, then work outward through the trunk lines and branch ducts. Every sealed joint is photographed before and after, and the photo record is delivered as part of the standard job file.
Flex Duct Repair
The 1980s-era flex duct in older DTC-corridor subdivisions was frequently installed without proper support hangers. Decades later, those runs sag where fine Colorado dust pools and airflow chokes. Our Duct Repair & Sealing team re-supports the runs with proper hangers, replaces crushed or torn sections, and seals the connections with mastic. We were called to a 4,100 sq ft multi-zone home off Belleview near the DTC where the upstairs zone was running long cycles and the primary bedroom never held temperature; camera inspection showed two sagging flex runs in the unconditioned attic that had been installed without support hangers, with visible dust pooling at the low points. Our tech re-supported the runs, replaced the crushed sections, sealed the plenum and boot connections with mastic, then re-balanced the zone - three systems, documented and priced separately, which is standard for this part of Greenwood Village.
Metal Duct Repair
Some Greenwood Village homes, particularly custom builds from the late 1980s and early 1990s, used galvanized metal trunk lines with branch takeoffs. We repair separated seams, replace corroded sections, and reseal with mastic after confirming structural integrity. Metal work costs more than flex repair but lasts longer in the dry Front Range climate where corrosion is minimal compared to humid regions.
Duct Insulation
Unconditioned attics in Greenwood Village can swing 40 degrees in a day. When we repair or replace ductwork in those spaces, we assess whether the existing insulation jacket is intact. Damaged insulation means the system works harder to deliver the same air. We replace it with properly rated material as part of the repair scope, photographed and documented like every other component.

Common Duct Repair & Sealing Problems We See in Greenwood Village Homes
- Aging fiberboard trunk lines delaminating at seams. The 1978-1998 executive homes that dominate Greenwood Village frequently have fiberboard trunks that separate at joints, leaking conditioned air into attics and crawl spaces. Camera inspection shows the delamination clearly, and repair means either resealing with mastic or replacing the section.
- Unsupported 1980s flex duct sagging and pooling dust. Subdivisions along East Orchard Road and Belleview are especially prone to this. The flex was strung tight in 1985, hangers failed, and now low points collect decades of Front Range dust that a standard cleaning won’t fully remove without re-supporting the run first.
- Multi-zone systems quoted as single-point repairs. A Greenwood Village home with three air handlers needs three separate scopes. Sealing one zone’s plenum while leaving the other two unaddressed is an incomplete fix that we won’t perform. Per-system pricing is standard here.
- Wildfire smoke particulate accelerating seal degradation. The 2020 season pushed fine particulate deep into HVAC systems across the Denver metro, including Greenwood Village. Smoke residue can degrade tape adhesives and collect at leaks, making existing gaps worse and creating new ones at stressed connections.
Pricing for Duct Repair & Sealing in Greenwood Village, CO
A typical duct sealing job on one system in Greenwood Village runs $400-$750. Flex duct repair with re-support and section replacement runs $600-$1,200 per system depending on attic accessibility and linear feet involved. Metal duct repair starts around $800 and can reach $1,500 per system for extensive seam work or section replacement. Multi-zone homes are scoped and priced per air handler, so a three-system property might run $1,200-$3,600 for complete sealing and repair across all zones.
What moves the number: attic vs. crawl space access, whether we can reach the runs without cutting drywall, how many sections need replacement versus resealing, and whether the plenum itself is intact. We deliver a written price before any work starts, every time, under Haven Standard Clause 1. No exceptions. Bring a competitor’s written estimate and we’ll provide a Free Second Opinion in writing.

FAQs - Duct Repair & Sealing in Greenwood Village
Because each air handler has its own supply and return ductwork, plenum, and boot connections that must be sealed and documented separately. A single flat rate would either overcharge a one-zone home or under-scope a three-zone property. In Greenwood Village’s DTC-era subdivisions, per-system pricing is the only honest way to deliver a complete, documented repair. Call (720) 315-7291 and we’ll scope each system in writing.
Camera inspection first, to locate delamination at joints and seams. Then either mastic resealing of intact sections or replacement of failed trunk line, followed by sealing all plenum and boot connections. The work is photographed before and after, and the photo record is delivered as part of the standard job file. Fiberboard from this era cannot be patched with tape; it needs mastic or replacement.
Yes. The extremely low humidity at 5,800 feet means dust stays airborne longer and coats duct interiors more thoroughly than in moister climates. Wildfire smoke events, notably 2020 across the Denver metro, drive particulate deep into HVAC systems and can degrade existing seals. Sealed ducts with intact connections are less vulnerable to both routine dust infiltration and smoke particulate accumulation. If your home is in the East Orchard Road or Belleview corridor with original 1980s ductwork, the combination of age and particulate load makes inspection worthwhile.
Our Documented Photo Record shows the inside of every duct run, every sealed joint, and every replaced section. You receive these photos as part of the standard job deliverable, along with the written scope and the 365-Day Done Right Promise. If a company won’t show you what they did, they didn’t document it. We have photographed every run on every job since 2013.
Often yes, if the trunk lines and air handlers are structurally sound. Sealing and re-supporting 1980s flex duct can restore airflow and reduce cycle times immediately, at a fraction of full replacement cost. We scope the condition first, report what we find with photos, and give you a written price for repair alongside an honest assessment of how much life remains in the system. If replacement is the better option, we’ll say so in writing. Call (720) 315-7291 for an inspection and written estimate.
