Duct Repair & Sealing in Aurora - We Measure the Leak Before We Quote

Fast, Reliable Duct Repair & Sealing Across Aurora

Duct repair and sealing in Aurora, CO typically runs $280-$650 for most residential systems, with full sealing of a 1960s-1980s ranch-style trunk-and-branch layout toward the higher end. For Aurora Dryer Vent Cleaning, we follow the same thorough approach. CleanRun crews are on the road daily from our Denver office to Aurora homes, and we carry the mastic, mechanical fasteners, and insulation to rebuild leaking joints rather than patch them.

We know the difference between a quick cleaning and a real fix because we’ve photographed the inside of over 52,000 duct runs since 2013. In Aurora, that means recognizing when a system is pulling attic dust through a separated collar faster than any brush can remove it. Our Duct Repair & Sealing team treats sealing as the primary repair, not an afterthought.

Why CleanRun Air Duct Cleaning Parker Is Aurora’s Preferred Duct Repair & Sealing Company

Aurora homeowners research before they call. They check whether a company publishes prices, documents work, and stands behind it in writing. CleanRun operates under the H.A.V.E.N. Standard, with Haven Standard Clause 1 requiring a written price before any panel comes off, and Haven Standard Clause 3 verifying that every crew member is background-checked, uniformed, and identified by name before arrival. Tomas Reyes established this protocol in 2013, and it has not changed.

Our reputation in Aurora is built on what we deliver: a Documented Photo Record of every duct run, before and after, included as a standard deliverable on every visit. No manager approval needed. The 365-Day Done Right Promise is backed in writing on every job. If the work is not right, we make it right.

Scheduling and dispatch run from our Denver office, so crews reach Aurora properties with the parts and equipment to complete sealing work in a single visit. We do not quote one price and invoice another. We do not offer “$79 specials” that become $800 once the van is in the driveway. Our Aurora customers receive one flat price per system, agreed in writing, with no per-vent add-ons.

Local knowledge matters here. A technician who has not worked in Aurora Hills or Hoffman Heights may not recognize that fibrous duct board from 1968 fragments differently than metal, or that east-side construction dust requires a different containment approach. Our crews have.

Our Duct Repair & Sealing Services in Aurora

Duct Sealing

Western and central Aurora’s 1960s-1980s ranch tracts were built with single-layer sheet-metal trunk-and-branch ducts sealed mostly by friction and gravity, so in Aurora Hills and Hoffman Heights we measure return-side leakage into crawlspaces and attics that draws in more High Plains clay dust and wildfire smoke than the system ever conditions. The real fix is mastic and mechanical sealing, not another brushing. We seal every accessible joint, collar, and tap with brush-applied mastic rated for duct pressure, then pressure-test to confirm the system holds. Typical sealing work in Aurora runs $320-$580 for a single-system ranch.

Flex Duct Repair

The 2000s-2010s builds in Tallyn’s Reach and Southshore use flex duct for branch runs, and we’ve found crushed or kinked sections where builders compressed lines against framing during the original construction rush. Flex duct does not recover its shape once flattened. We replace damaged sections with properly supported new flex, seal the collars with mastic, and photograph the repair. Aurora flex duct repairs typically fall between $180-$340 per run.

Metal Duct Repair

In Hoffman Heights we pulled a 1970s original branch run where the trunk tap had separated about an inch below the collar, blowing conditioned air and attic dust straight into the supply side. The customer’s complaint was a gritty smell every time the blower motor ramped on. We set negative pressure with HEPA filtration, did camera inspection, brushed and source-removed the run, then rebuilt the joint with mastic sealant and re-insulated it, and the system finally held pressure at the registers. Metal duct repair in Aurora ranges from $240-$520 depending on accessibility and extent.

Duct Insulation

Aurora’s temperature swings, from below-zero winter nights to 90-degree summer days, punish uninsulated ductwork in attics and crawlspaces. We install foil-faced fiberglass or closed-cell insulation over sealed metal runs, paying particular attention to the plenum, the main distribution box where conditioned air first enters the duct network. Proper insulation after sealing prevents condensation in summer and heat loss in winter. Most Aurora insulation work runs $280-$480 for accessible trunk lines.

Mastic Sealant Application

We apply mastic, a thick, fiber-reinforced paste that remains flexible after curing, to every metal joint we can reach. Tape alone fails; mastic with mechanical fasteners does not. In Aurora’s wind-driven dust environment, a sealed system is the difference between cleaning that lasts three years and cleaning that lasts three months. Mastic application is included in our standard sealing scope, not priced separately.

Air Leak Repair

Leak detection starts with a visual camera inspection and, where appropriate, a pressure differential test. We mark every leak, photograph it, repair it, and photograph the repair. The customer receives both images as part of the Documented Photo Record. In Aurora’s older housing stock, we typically find 8-15 significant leaks per system.

Trusted Brands We Service in Aurora

CleanRun crews carry professional-grade equipment from trade-recognized brands: Rotobrush brushing systems for mechanical agitation, Nikro negative-pressure extractors for source removal, and Honeywell media filters for post-repair air quality verification. We stock mastic, mechanical fasteners, and insulation materials sized for Aurora’s common duct configurations, so most sealing work completes without a return trip for parts. Our equipment roster is published so customers can verify what will be used before agreeing to a price.

Common Duct Repair & Sealing Problems We See in Aurora Homes

• Original single-layer sheet-metal joints in 1960s-70s west-side ranches leak at every trunk tap, so the system keeps pulling crawlspace and attic air back in no matter how often it is cleaned. We find this in Aurora Hills and Hoffman Heights on most calls. Mastic sealing is the only lasting fix.
• Aging fibrous duct board in Aurora Hills and Hoffman Heights fragments into the airstream; without negative-pressure containment set before agitation tools start, the cleaning itself liberates fiberglass into living areas. This protocol failure mode comes up far more often in Aurora’s older west-side stock than in comparable Denver suburbs.
• East-side 2000s-2010s builds like Tallyn’s Reach and Southshore still sit beside active construction, so freshly cleaned supply and return ducts recharge with drywall and framing dust faster than a normal service interval covers. Sealing the system tight reduces this recontamination.
• Wildfire smoke events deposit ultrafine combustion particulates deep into duct systems that ordinary filter maintenance does not remove. In Aurora, exposed to both prairie dust from the east and mountain wildfire smoke from the west, these particulates enter through leaks that sealing eliminates.
