AfterTrusted Duct Repair & Sealing for Parker Homeowners
Duct Repair & Sealing - Parker typically costs $280-$780 for most residential jobs, with full-system sealing running higher depending on home size and accessibility. CleanRun Air Duct Cleaning Parker has completed this work in over 52,000 homes since 2013, and every job starts with a written price delivered before any panel comes off. If your rooms heat unevenly, your energy bills spike without explanation, or you feel weak airflow at registers, the problem is often leaks or damage in the duct runs behind your walls.
We’re independently owned and operated under the Haven Standard, led by Tomas Reyes, and we serve Parker homeowners with the same process on every visit: a written quote, documented photo record of every duct run, and a 365-Day Done Right Promise backed in writing. Our technicians are background-checked, uniformed, and identified by name before arrival. Call (719) 259-4520 to speak with a live person and schedule your free estimate.
What Our Duct Repair & Sealing Service Includes
Duct Sealing
Duct sealing closes the gaps, cracks, and disconnected joints that allow conditioned air to escape into your attic, crawl space, or wall cavities. In Parker, we regularly find that 20-30% of heated or cooled air never reaches the living space due to these leaks, which is especially costly given our temperature swings from below-zero winters to 90-degree summer days. Our crew uses professional-grade mastic sealant and metal-backed tape, not the gray cloth tape that dries and fails within a season, and every sealed joint is photographed before and after as part of your documented photo record.
Flex Duct Repair
Flex duct, the ribbed plastic tubing common in homes built from the 1990s onward, collapses, tears, or disconnects at the collar where it meets the plenum or register box. In Parker’s newer subdivisions like Pradera and Canterberry, we’ve replaced entire flex runs that were crushed during original construction and hidden behind drywall for years. Our repair includes proper support strapping every 4 feet to prevent sagging, collar reinforcement with mechanical fasteners, and pressure testing to verify airflow restoration.
Metal Duct Repair
Galvanized steel ductwork, found in homes built before 1990 and in many custom builds, corrodes at the seams, separates at the S-lock joints, or develops holes from condensation damage. Parker homes near Cherry Creek and the older ranch properties east of Parker Road often show rust where humid summer air meets cool metal. We repair with matching gauge steel, sealed with mastic and reinforced mesh, or replace sections when corrosion has compromised structural integrity. Every repair is photographed and included in your job record.
Duct Insulation
Uninsulated or degraded duct insulation in unconditioned spaces wastes energy and creates condensation that leads to mold and metal fatigue. In Parker, where attic temperatures can exceed 140°F in July, R-6 or R-8 insulation on flex duct and fiberglass wrap on metal runs is essential. We install foil-faced insulation with sealed seams, vapor barriers intact, and proper clearance from combustion appliances, all documented in your before-and-after photo record.
Mastic Sealant Application
Mastic is a water-based, fiber-reinforced compound that remains flexible after curing, making it the professional standard for sealing duct joints and seams. Unlike tape, which degrades, mastic fills irregular gaps up to 1/8 inch and bonds to metal, flex duct, and fiberglass insulation. Our technicians apply mastic with a brush or caulking gun to all longitudinal seams, transverse joints, and register connections, then photograph the work before the compound skins over. This is standard procedure on every sealing job, not an upsell.
Air Leak Repair
Air leaks in ductwork often manifest as whistling, temperature stratification between rooms, or excessive dust near registers. We locate leaks using pressure differential testing and visual inspection with borescope cameras, then repair according to the material: mastic and mesh for metal, collar replacement for flex, or full run replacement when damage is extensive. In Parker, we commonly trace leaks to original construction shortcuts: unsealed plenum connections, missing end caps, or registers cut into duct runs without proper boots.

Brands We Service for Duct Repair & Sealing
We’ve worked on duct systems connected to Honeywell zoning panels and Aprilaire whole-home air cleaners throughout Parker and the surrounding Denver metro area. Honeywell’s zone dampers require precise duct pressure balance to function correctly, and we’ve documented cases where sealing leaks restored zone performance without replacing the control board. Aprilaire media air cleaners need sealed return ductwork to maintain their rated MERV efficiency; a leaky return pulls unfiltered air from the attic, bypassing the filter entirely.
We also service duct systems paired with Nikro negative-air machines and Abatement Technologies HEPA filtration, equipment we use ourselves on cleaning jobs and understand from both sides. Whether your system includes these brands or any other make, we can assess, repair, and seal the ductwork to manufacturer specifications. Every recommendation is delivered in writing with a fixed price before work begins.
BeforeAfterSigns You Need Duct Repair & Sealing Right Now
- Uneven heating or cooling between rooms. If your master bedroom is 10 degrees warmer than the hallway in summer, or your basement never reaches the thermostat setpoint, the duct run serving that space is likely leaking, disconnected, or blocked. This isn’t a thermostat problem; it’s a distribution problem that sealing or repair can fix.
- Energy bills that rise without usage changes. When conditioned air escapes before reaching registers, your HVAC system runs longer to hit the setpoint. We’ve seen Parker homeowners reduce summer cooling costs by 15-25% after sealing leaks in attic duct runs.
- Weak airflow at registers despite a running blower. Place your hand over a vent. If the stream is barely perceptible but the system is on, air is being lost to a breach in the ductwork. Common culprits include disconnected flex duct, collapsed sections, or open dampers that should be sealed.
- Dust accumulation immediately after cleaning. If surfaces coat with dust within days of vacuuming, your return duct may be pulling air from a dusty attic or crawl space through a gap or missing filter seal. This bypasses your filter and circulates construction debris and insulation particles.
- Whistling or rushing noises from walls or ceilings. These sounds indicate high-velocity air escaping through a small opening, often a separated joint or a hole corroded through metal duct. The noise is the symptom; the energy loss and potential for condensation damage are the problems.
Our Duct Repair & Sealing Process - Step by Step
- 1
Written estimate before work begins. We inspect your accessible ductwork, identify leaks or damage with borescope cameras and pressure testing, and deliver a fixed-price scope in writing. Haven Standard Clause 1: no work starts without a written price agreed to by the homeowner.
- 2
Documented photo record of existing conditions. Before touching any duct run, we photograph the interior through access ports and the exterior where visible. These images establish baseline conditions and often reveal problems the homeowner wasn’t aware of: standing water in low points, mold on insulation, or disconnected collars hidden above drywall.
- 3
Targeted repair and sealing. We repair or replace damaged sections using materials matched to the existing system, then seal all joints with mastic and appropriate reinforcement. For metal duct, this means mesh tape and mastic; for flex, mechanical collars and support straps; for insulation, foil-faced wrap with sealed seams.
- 4
Pressure test and airflow verification. After sealing, we pressurize the system and measure static pressure at the air handler and key registers. The post-repair readings are compared to manufacturer specifications and to our pre-repair baseline, with results noted on your job record.
- 5
Final photo record and written warranty delivery. We photograph every repaired or sealed joint, compile the before-and-after images into your documented photo record, and leave you with the 365-Day Done Right Promise in writing. If airflow, temperature balance, or seal integrity fails within a year, we return to make it right.
How Much Does Duct Repair & Sealing Cost in Parker?
A typical duct sealing job for a single-family home in Parker runs $280-$550 for accessible attic and basement runs, while extensive sealing throughout the system, including wall cavities and crawl spaces, ranges from $480-$780. See how much Duct Repair & Sealing costs for more detail. Flex duct repair, including replacement of a damaged run up to 25 feet, typically falls between $320-$620 depending on accessibility and whether register boots or plenum connections also need work. Metal duct repair starts around $340 for localized seam sealing and can reach $680 or more when multiple sections require replacement with matching gauge material.
Several factors move the price within these ranges. Attic work in July or January takes longer due to temperature extremes, and tight crawl spaces add labor time. Homes with finished basements may need strategic access cuts, which we discuss and price before cutting. The age of the system matters too: ductwork from the 1970s and 1980s often needs more extensive repair than systems installed after 2000.
To avoid overpaying, get any quote in writing with line-item scope, and verify that sealing materials are mastic-based, not tape-only.
