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.
Fast, Reliable Duct Repair & Sealing Across Arvada
Duct repair and sealing in Arvada typically runs $340-$890 for most residential jobs, with written quotes delivered before any panel comes off. Our crews coordinate dispatch from our Denver office and carry the equipment to reach Arvada homes, including the tight access points and shared building systems common in denser neighborhoods. Call (720) 799-2292 for a free written estimate with no obligation.
We’ve worked in Arvada since 2013, and the housing stock here is unlike anywhere else in the metro area. The 1955-1975 ranch tracts that dominate Ralston Hills, Scenic Heights, and similar neighborhoods were built with unlined stud-wall cavities serving as return-air chases - not dedicated sheet-metal returns. That single construction choice changes everything about how duct sealing and repair must be scoped, priced, and executed. Our Duct Repair & Sealing team scopes every wall cavity with a camera before writing a price, because we’ve learned what happens when crews skip that step.
Why CleanRun Air Duct Cleaning Denver Is Arvada’s Preferred Duct Repair & Sealing Company
Arvada homeowners have left us documented reviews describing specific findings: fiberglass batt debris removed from wall cavities, before-and-after photos of sealed metal liners, and written prices that matched the final invoice. We don’t ask for trust; we deliver a photo record and a written scope.
Our response time to Arvada averages same-day or next-day scheduling, depending on the job complexity. Cavity scoping and source removal take longer than register-level cleaning, so we build realistic windows and arrive when we say we will.
We know the local conditions that affect your ducts. At roughly 5,400 feet on the semi-arid Front Range, Arvada’s persistently low relative humidity keeps fine particulates airborne longer - pollen, clay-soil dust, and drywall debris from active western-corridor construction all cycle aggressively through forced-air systems. Chinook wind events strip topsoil from open lots and foothills terrain west of Arvada and deposit coarse mineral grit around return-air intakes at rates that flatter, eastern-metro homes don’t experience. That grit accelerates leak paths and contaminates duct interiors in ways standard assumptions miss.
Tomas Reyes leads our operations, and every crew working in Arvada operates under the H.A.V.E.N. Standard with background-checked, uniformed technicians identified by name before arrival.
Our Duct Repair & Sealing Services in Arvada

Duct Sealing
Arvada’s original galvanized sheet-metal runs, especially in slab-on-grade ranches, leak at hand-cut joints and branch takeoffs that were never sealed with mastic at installation. Our duct sealing process applies NADCA-standard sealing to supply and return ducts, not just visible registers. In Ralston Hills and Scenic Heights homes with wall-cavity returns, we seal only after source removal and metal-liner installation - sealing debris-packed cavities traps contaminants and worsens air quality. A typical duct sealing job in Arvada runs $340-$620 for a single-system ranch home.

Air Leak Repair
Chinook mineral grit and decades of thermal cycling have opened leak paths in Arvada ductwork that don’t show up until a pressure test. We pressurize the system, identify leakage points with smoke or digital detection, then repair with mechanical fastening and mastic sealant rated for the temperature swings these systems see. Air leak repair in Arvada typically falls between $280-$540 depending on accessibility and the number of leak points.

Metal Duct Repair
Original sheet-metal ducts in Arvada’s 1955-1975 housing stock corrode at seams, collapse at unsupported spans, and separate at original hand-cut joints. We repair with galvanized patch material, mechanical drives, and mastic - or replace sections where corrosion has compromised structural integrity. Metal duct repair in Arvada runs $380-$750 for most residential jobs, with full replacement of a compromised run quoted separately if needed.

Flex Duct Repair
The 1980s-1990s two-story homes in newer Arvada subdivisions added flex-duct systems now entering their first major service cycle. Flex duct crushes at tight bends, separates at collars, and deteriorates where attic temperatures exceed material ratings. We repair with properly supported replacement flex, sealed collars, and insulation restoration. Flex duct repair in Arvada typically costs $260-$480 per run.

Duct Insulation
Condensation on uninsulated or degraded ductwork is less common in Arvada’s dry climate than in humid regions, but temperature stratification in unconditioned crawl spaces and attic runs still wastes energy. We install foil-faced fiberglass or closed-cell insulation where thermal bridging occurs, with particular attention to slab-on-grade homes where ductwork runs through perimeter soffits exposed to exterior wall temperatures.

AfterTrusted Brands We Service in Arvada
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation inside duct runs, Nikro negative-pressure extractors for source removal, and Honeywell and Aprilaire air-handler components we stock for common replacement scenarios in Arvada homes. These are professional-grade tools customers can look up independently - we name them because the Haven Standard requires equipment transparency, not because the brands need promotion. For Arvada jobs, we carry mastic sealant, metal liner stock, and flex-duct replacement material sized for the dimensions common in local 1955-1975 ranch construction, which reduces return trips and keeps quoted prices accurate.
Common Duct Repair & Sealing Problems We See in Arvada Homes

- Unlined stud-wall return chases in Ralston Hills and Scenic Heights ranches. Builders used interior wall cavities as return-air plenums with no sheet-metal liner. After 50-plus years, these cavities hold compacted fiberglass batt debris, rodent nesting material, and chinook dust that bypasses the filter entirely. Technicians who skip scoping before quoting routinely underprice the sealing job.
- Leaking hand-cut joints in original galvanized sheet-metal runs. Slab-on-grade tract homes from the 1955-1975 era rely on supply and return ducts with joints that were never sealed to modern standards. Sealing must address the full duct network, not just register boots.
- Chinook-deposited mineral grit accelerating leak paths. On Arvada’s west side near the foothills, coarse grit from chinook events and active construction accumulates at return-air intakes. This grit abrades duct interiors and opens leak paths faster than in eastern-metro suburbs with flatter terrain and less wind exposure.
- Shared building systems in dense Arvada apartments and condos. Multi-unit buildings with common ductwork or stacked utility chases require coordinated scheduling, restricted parking protocols, and containment procedures that single-family crews often lack experience with.
Pricing for Duct Repair & Sealing in Arvada, CO
We publish ranges because Haven Standard Clause 1 requires written pricing before any work starts. Here is what duct repair and sealing costs in Arvada’s market:
| Service | Typical Range in Arvada |

| Wall-cavity return scoping + source removal | $180 - $340 |
| Metal liner installation (per cavity) | $220 - $420 |
Factors that move the price: accessibility (crawl space versus attic), number of leak points found during pressure testing, whether wall-cavity returns require scoping and liner installation, and the condition of existing duct supports. Every quote includes the Documented Photo Record as a standard deliverable - no add-on. Call (720) 799-2292 for a written estimate; we’ll scope the system, photograph what we find, and deliver a fixed price before any work begins.

FAQs - Duct Repair & Sealing in Arvada

Because builders in neighborhoods like Ralston Hills and Scenic Heights commonly used unlined interior stud-wall cavities as return-air chases instead of dedicated sheet-metal returns. After 50-plus years, these cavities contain compacted fiberglass batt debris, rodent nesting material, and chinook dust that bypasses the filter entirely. Sealing over this debris traps contaminants and worsens air quality. We scope every cavity with a camera before writing a price, per Haven Standard Clause 1. Call (720) 799-2292 to schedule scoping and a written estimate.
Slab-on-grade ranches rely on original galvanized sheet-metal runs that leak at hand-cut joints and branch takeoffs; sealing requires NADCA-standard mastic application throughout the supply and return network, often after wall-cavity scoping. The 1980s-1990s two-story homes use flex-duct systems that crush at bends and separate at collars; sealing focuses on collar integrity, proper support, and insulation restoration. The scope, equipment, and price differ substantially between the two. We’ll assess which system you have and quote accordingly.
Yes, with coordination. Shared building systems require containment protocols to prevent cross-contamination, scheduling that respects building management requirements, and equipment sized for restricted parking and access points common in denser Arvada developments. We document the scope in writing, coordinate with building maintenance where required, and deliver the same photo record and fixed price as single-family jobs. Call (720) 799-2292 to discuss your building’s specific configuration.
Chinook wind events strip topsoil from open terrain west of Arvada and deposit coarse mineral grit around return-air intakes. This grit abrades duct interiors, accelerates leak path development at joints and seams, and contaminates the system with particulate that standard filters don’t capture. Homes on Arvada’s west side typically show faster duct deterioration and higher debris loads than eastern-metro properties with similar maintenance histories. Our scoping process identifies grit accumulation and our source removal clears it before sealing.
We coordinate arrival windows with building management, use compact negative-pressure extractors sized for tight utility rooms, and carry containment materials by hand when loading docks or service elevators aren’t available. The H.A.V.E.N. Standard requires pre-job site assessment - Haven Standard Clause 2: Prepared Arrival - so we confirm access, parking, and building protocols before quoting. No surprises for you or your building manager.
