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 Arvada
Duct repair and sealing in Arvada typically runs $280-$750 for most residential jobs, with full-system resealing on older homes reaching $900-$1,400. We dispatch crews to Arvada daily from our Denver office, and most inspections are scheduled within 48 hours. Call (720) 315-7291 for a written estimate before any work begins.
Arvada’s neighborhoods from Olde Town to Candelas sit in a unique spot, tucked against the Front Range where Chinook winds push foothills dust straight through the city. We’ve worked in Arvada since 2013, and the pattern is consistent: the dusty air homeowners blame on dirty ducts often traces back to broken seals, degraded duct board, or disconnected runs that a basic cleaning cannot fix. Our Duct Repair & Sealing team documents every joint and seam with before-and-after photos so you see exactly what was failing and what we sealed.
Why CleanRun Air Duct Cleaning Littleton Is Arvada’s Preferred Duct Repair & Sealing Company
We’ve completed thousands of jobs in Arvada’s 80002, 80003, 80004, 80005, and 80007 zip codes, from the original ranch blocks near Wadsworth to the newer foothills builds above Highway 93. Our reviews from Arvada customers consistently cite two things: the photo record showing what was actually broken, and the written price delivered before a tool came out of the van.
Dispatch and scheduling are coordinated from our Denver office, but crews live and work in the northwest metro. That means familiarity with Arvada’s specific housing stock, the 1955-1978 ranch and tri-level concentration that defines so much of the city, and the permit requirements Jefferson County enforces for duct modifications in finished spaces. Haven Standard Clause 3, Verified Crews, means every technician is background-checked, uniformed, and identified by name before arrival.
The 365-Day Done Right Promise applies to every Arvada job in writing. If a seal fails or a repair doesn’t hold, we make it right without a service charge. Not a policy subject to manager approval. A written guarantee.
Our Duct Repair & Sealing Services in Arvada
Duct Sealing
Most Arvada homes we inspect leak 20-35% of conditioned air before it reaches the registers. The culprit is usually original galvanized seams that have worked loose over sixty years, or crimped joints that were never sealed beyond a friction fit. We pressure-test the system, mark every leak, then seal with mastic or foil tape rated for the temperature swing these ducts see. A typical duct sealing job in Arvada runs $450-$900 depending on system size and access.
Flex Duct Repair
Flex runs in Arvada’s tri-levels and ranches get crushed under insulation, pinched by retrofit wiring, or disconnected where they tie into trunk lines. In western Arvada’s Candelas area, we also find post-construction drywall dust hardened inside flex runs by the area’s gusty, low-humidity conditions. We replace damaged flex with insulated R-6 or R-8 drops, secure with mechanical ties (not zip strips), and photograph the tie-in. Flex duct repair in Arvada typically costs $180-$340 per run.
Metal Duct Repair
Original galvanized trunk lines in Arvada’s 1960s and 1970s homes corrode at the seams, separate at pop-riveted joints, or sag where supports have failed. We re-secure with sheet-metal screws, reinforce with mastic-backed tape, and replace sections where rust-through has compromised the duct wall. Metal duct repair in Arvada runs $250-$600 per section depending on access and extent.
Duct Insulation & Mastic Sealant
Uninsulated or poorly insulated ducts in Arvada’s unfinished basements and crawlspaces lose heat in winter and gain it in summer, forcing the HVAC system to run longer. We apply water-based mastic sealant (a thick, brush-on compound that cures to a flexible seal) to all joints and seams, then wrap with formaldehyde-free fiberglass insulation where the duct passes through unconditioned space. Mastic sealing and insulation work in Arvada typically ranges $380-$780.

Common Duct Repair & Sealing Problems We See in Arvada Homes
- Loose galvanized seams pulling basement air into the return. The original crimped joints on 1955-1978 sheet-metal trunks separate over decades, so the air handler draws unconditioned basement or crawlspace air instead of return air from the house. You feel it as weak airflow and dust that never seems to settle.
- Fiberglass duct board shedding glass fibers downstream. Common in that era’s basement installations, the internal facing degrades and sends particulate through supply registers. Homeowners often describe it as “glitter in the dust” or notice increased filter loading. The fix is replacement or encapsulation, not cleaning.
- Crushed flex runs in tri-level knee walls and floor joists. A flex duct pinched during a remodel or settled under insulation dumps conditioned air into a joist cavity. The room stays cold in winter; the duct looks fine from the register side. Camera inspection finds it every time.
- Post-construction debris locked in Candelas flex duct. The dry, windy conditions in Arvada’s newer foothills-adjacent developments set drywall dust and fine grit before the homeowner ever runs the system. New-construction duct cleaning and sealing is unusually common there, and we document the load with photos.

FAQs - Duct Repair & Sealing in Arvada
The dust is likely coming from inside the duct system itself, not past the filter. Arvada’s 1955-1978 ranch and tri-level homes in the Wadsworth/Kipling/Ralston Road corridors commonly still run original galvanized sheet-metal ductwork paired with fiberglass duct board sections that degrade internally - so the dusty air you notice is often a broken duct-board lining shedding fiberglass, not just settled debris. That combination is denser here than in the newer, flatter suburbs to the east. Camera inspection shows it clearly, and the fix is usually sealing or replacing the degraded sections, not another cleaning. Call (720) 315-7291 for a written inspection quote.
Yes, in most cases. We access ducts through existing registers, return grilles, and small service openings; for trunk-line work behind drywall, we locate the precise failure point with a camera before cutting any access panel. At a 1962 tri-level off Ralston Road near Kipling, our tech ran a camera inspection and found a crushed flex run to the back bedroom and a three-foot section of original galvanized trunk pop riveted loose at a joint. After a Rotobrush source removal down both supply and return ducts - including the register boots - we sealed the joint with mastic, re-secured the trunk with foil tape and screws, and tied in a fresh insulated flex drop. The homeowner had been chasing dust for years and the fix was mostly sealing, not scrubbing. We photograph every step so you see what was accessed and how. Written quote before any drywall is touched.
Yes. Arvada sits at approximately 5,350 feet on the eastern slope of the Front Range, where periodic Chinook wind events push dry, particulate-laden air off the foothills directly into the city. During Colorado’s increasingly severe wildfire seasons, smoke from fires in Jefferson County canyons (Coal Creek, Clear Creek, Lefthand) infiltrates HVAC systems and deposits fine combustion particles deep into duct runs that standard filter changes cannot address. Sealed ducts resist this infiltration; leaky ducts pull it in continuously. The pressure differential during Chinook events can be strong enough to force dust through gaps that would stay dormant in calmer conditions. We test for these pressure-driven leaks specifically in Arvada homes.
Technicians working in western Arvada’s newer foothills-adjacent developments like Candelas consistently find post-construction drywall dust and fine-grit debris locked in flex duct runs. The gusty, low-humidity conditions there dry and set construction particulate before homeowners ever run the system for the first time, making new-construction duct cleaning and sealing unusually common in that part of the city. We’ve also found disconnected flex ties and gaps at trunk connections that the builder’s crew missed. Camera inspection confirms whether the issue is debris, disconnection, or both. Written estimate before any work.
We use a combination of camera inspection, airflow measurement at each register, and negative-pressure testing to map exactly where conditioned air is being lost. A disconnected flex run in a tri-level’s floor joist or knee wall typically shows as a room with 30-50% lower airflow than the design spec, even though the register is open and unobstructed. The camera confirms the break location, and we access it through the nearest register boot, basement ceiling, or a small, precisely located access panel. Every finding is photographed before any repair begins. Call (720) 315-7291 to schedule; estimates are free and written.
