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 The Pinery
Duct repair and sealing in The Pinery typically runs $280-$890 per system depending on access, material type, and whether we’re resealing original trunk-and-branch metal or replacing damaged flex-duct runs. Most The Pinery homes need multiple systems addressed, and our crews finish the average multi-system job in one working day. Call (720) 513-5159 for a written price before any work starts.
We serve The Pinery from our Denver office, with crews running daily routes through Douglas County. The forested lots off Pine Needle Lane, the custom builds near Ponderosa Road, and the semi-custom ranches along Hilltop Road - we’ve worked on all of them. The Pinery isn’t a quick off-ramp stop for us. It’s a distinct service profile: multi-acre properties, multiple air handlers, and duct systems that fail in ways you’ll never see in Aurora or Centennial.
Our Duct Repair & Sealing team knows what to look for here. The Ponderosa canopy surrounding your home isn’t scenery - it’s the reason your return filters load up differently than your neighbor’s in Parker.
Why CleanRun Air Duct Cleaning Aurora Is The Pinery’s Preferred Duct Repair & Sealing Company
We’ve been serving The Pinery since we first ran routes into Douglas County in 2013. In that time, we’ve documented photo records from over 1,200 The Pinery homes, and the pattern is consistent: original duct tape and mastic from the 1970s-1990s builds has failed, flex-duct runs have been compromised by rodents or compression, and fresh-air intakes are packed with pine debris that suburban technicians simply don’t encounter.
Our reviews from The Pinery customers center on the same detail - the photo record. Homeowners here are sophisticated buyers who researched before calling. They mention specifically that we showed them the inside of every duct run before proposing work, and that the written price they agreed to was the price on the final invoice. Haven Standard Clause 1: Written Price Before Any Work Starts. No exceptions.
Response time to The Pinery is typically next-business-day for non-urgent sealing work, with scheduling coordinated from our Denver office. For jobs requiring camera inspection and static-pressure testing across multiple systems, we block longer windows so the crew isn’t rushing through your third air handler at dusk.
Local knowledge matters because The Pinery’s housing stock is unique. These aren’t tract-home flex-duct systems installed in 2019. They’re 30-50-year-old trunk-and-branch designs, often attic-routed, frequently modified by owners who didn’t understand static pressure. Our technicians carry mastic rated for the temperature swings these attics see, and they know to check for compacted pine needle mats before condemning a blower motor.
Our Duct Repair & Sealing Services in The Pinery
Duct Sealing
Duct sealing in The Pinery starts with a pressure test, not a sales pitch. We pressurize your system and measure leakage at the plenum (the main distribution box), at each takeoff, and at the register boots. In The Pinery’s older homes, we regularly find total leakage exceeding 25% of conditioned airflow - air you’ve paid to heat or cool, escaping into attic spaces filled with pine pollen and insulation fragments. Our sealing protocol uses mastic sealant on metal joints and proper collar connections on flex transitions, not foil tape that’ll bake out in two seasons. For homes with multiple systems, we seal and test each independently under Haven Standard Clause 2: Verified Results.
Flex Duct Repair
Flex duct in The Pinery takes abuse that doesn’t happen in open subdivisions. Rodents move through the forested lots, and crushed or chewed flex runs are common on multi-acre properties where the original installer ran duct through crawl areas or buried it in attic insulation. We replace damaged flex with new insulated duct, support it properly to prevent sagging, and seal the connections with mastic and mechanical fasteners. Every repaired run gets a before-and-after photo - part of our standard Documented Photo Record on Every Visit, a practice we’ve held since 2013.
Metal Duct Repair
The Pinery’s 1970s-1990s trunk-and-branch metal systems are reaching end-of-life on their original seals. We see rust-through at low points where condensation collected, separated seams from decades of thermal cycling, and takeoffs that were never properly sealed to begin with. Our metal repair includes patching or replacing damaged sections, resealing all joints with brush-applied mastic, and reinstalling with proper slope and support. For severely compromised mains, we’ll document the damage with camera footage and present options - repair or targeted replacement - with a written price for each.
Duct Insulation
Attic-routed ductwork in The Pinery loses efficiency through conduction in winter and gains heat in summer. We install or replace insulation on accessible runs, using materials rated for the temperature extremes these attics see at 6,200 feet. Insulation work is always paired with sealing - insulating a leaky duct just preserves the leak. We photograph insulation condition during our initial inspection so you can see what we’re describing.
Mastic Sealant Application
Mastic is the only sealant we use on metal joints in The Pinery. Foil tape fails. Duct tape fails faster. Mastic remains flexible, fills irregular gaps, and is rated for the temperature range your attic experiences. We brush-apply it to every joint, collar, and penetration, then verify with a post-sealing pressure test. The work is slow. It costs more than a tape-and-go job. It also lasts.
Air Leak Repair
Air leak repair addresses the envelope penetrations that let Palmer Divide wind events pressurize your home and force unfiltered outdoor air into return cavities. We seal around duct boots where they pass through drywall, repair disconnected returns, and verify that fresh-air intakes are drawing from the correct source - not from a compromised attic penetration. In The Pinery, this work often reveals the real cause of “dirty duct” symptoms: leaks so severe that your system has been filtering attic air and forest debris, not recirculating conditioned air.

BeforeAfterTrusted Brands We Service in The Pinery
Our equipment roster includes Rotobrush agitation tools for dislodging compacted debris, Nikro negative-pressure extractors with HEPA filtration, and Honeywell and Aprilaire components for air-handler repairs and filter upgrades. We stock common fittings and sealants locally, so The Pinery jobs aren’t delayed waiting for parts from Denver. When your system needs a component we don’t carry, we source it with next-day availability rather than substituting an inferior match. Every brand we name is one you can look up independently - no proprietary equipment, no mystery tools.
Common Duct Repair & Sealing Problems We See in The Pinery Homes
- Failed original seals on 30-50-year-old metal systems. The duct tape and mastic installed when your home was built has baked, cracked, and separated. We find supply leaks so severe that rooms at the end of the run get no airflow, while the attic gets heated and cooled instead.
- Compacted pine needle mats in fresh-air intakes and return grilles. This failure mode is essentially nonexistent in open subdivisions. In The Pinery, our technicians check for it on every call - a mat dense enough to mimic a failed filter, restricting airflow and overworking blowers.
- Rodent-damaged or crushed flex-duct runs on forested lots. Multi-acre properties with heavy tree cover see more rodent activity than open-plain communities. Flex duct in crawl spaces and attics becomes a highway or a nesting site, and insulation compression from later work turns runs into permanent airflow restrictions.
- Unsealed envelope penetrations letting Palmer Divide wind drive debris indoors. Sustained wind events at this elevation pressurize homes through every gap. Leaky return cavities become intake paths for pollen, wildfire smoke, and fine forest dust - your filter never sees it because it enters downstream of the filter location.

FAQs - Duct Repair & Sealing in The Pinery
Each air handler is a separate system with its own duct network, plenum, and leakage profile. Sealing one doesn’t fix the others, and per-vent pricing would triple-count your home unfairly. We price per system, so a three-handler home gets three written prices - one for each network we test, seal, and verify independently. Call (720) 513-5159 and we’ll scope each system on the same visit.
Ponderosa pine pollen peaks in late spring, and The Pinery’s dense canopy produces concentrations that open-plain communities don’t experience. Combined with Palmer Divide wind events driving that pollen through every unsealed penetration, your filters are working overtime. Duct sealing reduces the unfiltered air entering your system, which extends filter life and reduces the pollen load your blower is fighting. We’ve documented this specifically in The Pinery homes after sealing - filter replacement intervals typically double.
We look. Our technicians physically inspect fresh-air intakes, return grilles, and filter housings on every The Pinery job - it’s part of our standard opening protocol, not an extra. If we find compacted needle mats, we photograph them, remove them under negative-pressure extraction, and show you the before-and-after. This failure mode is so common in The Pinery that we don’t wait for symptoms to check.
Yes, but with limits. Sealing your duct system and envelope penetrations reduces the pathways through which smoke-laden outdoor air enters your conditioned space. It does not make your home airtight - that’s not the goal - but it does shift your air balance toward filtered, recirculated air rather than unfiltered infiltration. During severe wildfire events, sealing plus proper filter upgrades (MERV 13 or higher, compatible with your air handler) provides measurable reduction in indoor PM2.5. We’ve verified this with post-sealing air-quality testing in The Pinery homes.
You receive three concrete deliverables on every job: a written scope of work signed before we start, a Documented Photo Record showing the inside of every duct run before and after, and a post-work pressure test report verifying leakage reduction. These are standard, not optional, and they’re backed by the 365-Day Done Right Promise - if the work is not right, we make it right, in writing on every invoice. Haven Standard Clause 4: Documented Accountability.
On a multi-acre lot off Pine Needle Lane, our crew arrived to a 1970s-era ranch with three separate air handlers: two attic-routed trunk-and-branch sheet-metal systems originally tied together with duct tape and one newer flex-duct run. The homeowner was on their third blower motor and joked that their return filters turned yellow-green within days every May and June. We performed camera inspection and source removal under negative pressure with HEPA filtration, found the old tape and mastic had failed at nearly every takeoff, and used Rotobrush agitation tools to clear needle fragments lodged in the attic runs. After resealing with mastic and re-checking static pressure on all three systems, the homeowner’s filter life and airflow numbers finally stabilized.
