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 Pasadena
Duct repair and sealing in Pasadena, TX typically runs $280-$740 per system depending on access, material type, and whether post-Harvey contamination requires source removal before sealing work begins. Most Pasadena homes with multiple air handlers need per-system pricing, not a flat whole-home rate. Call (346) 253-1822 for a written estimate before any work starts.
We’ve been dispatching crews to Pasadena from our Houston office since 2013, and the route down State Highway 225 past the refineries is familiar enough that our technicians recognize the shift in housing stock before they check the address. Pasadena’s slab-on-grade ranches near Burke Road and Richey Street carry different duct problems than the newer builds we see in Pearland or Friendswood - three separate systems are common, original fiberglass duct board from the 1970s is still in service, and the refinery corridor leaves a greasy particulate film that standard cleaning won’t touch. Our Duct Repair & Sealing crews arrive with mastic, metal transition pieces, and the expectation that they’ll need to document work inside runs the homeowner can’t see.
Why CleanRun Air Duct Cleaning Pearland Is Pasadena’s Preferred Duct Repair & Sealing Company
Pasadena homeowners have left us reviews mentioning specifically that they chose us after a competitor quoted a flat rate over the phone and then tried to upsell in the driveway. We don’t operate that way. Haven Standard Clause 1 requires a written price before any panel comes off, and that price is per system - which matters in a city where a single ranch can have three air handlers.
Our response time to Pasadena is typically same-week scheduling, with crews carrying Rotobrush agitation tools and Nikro HEPA extraction equipment on every truck. Dispatch is coordinated from our Houston office, but the technicians who arrive at your door know Pasadena’s housing stock: the post-war builds south of Spencer Highway, the 1970s expansions near Fairmont Parkway, the converted garages that got flex duct runs never designed for the load.
We’re independently owned and operated under the Haven Standard, not a franchise network. Tomas Reyes established CleanRun in 2013, and every job since then - all 52,000-plus - has concluded with a Documented Photo Record delivered to the customer. Pasadena residents get the same accountability.
Our Duct Repair & Sealing Services in Pasadena
Duct Sealing
Duct sealing in Pasadena runs $280-$450 per system for mastic application at accessible joints and plenum connections. The price climbs when we find delaminated fiberglass duct board along the seams - common in original 1970s runs near Richey Street where decades of 90% humidity have separated the liner from the shell. We photograph every joint before sealing, apply mastic with a brush or spray depending on access, and document static-pressure improvement after the work. Sealing without inspection is pointless in this market; the refinery-corridor particulate has already infiltrated the leaks, and it’ll redistribute through any gap we miss.
Flex Duct Repair
Flex duct repair in Pasadena typically costs $320-$580 per run, including removal of collapsed or contaminated sections and replacement with new insulated flex or transition to metal where the run passes through unconditioned space. Post-Harvey, we’ve replaced dozens of flex runs in slab homes where floodwater wicked into the lower sections and the liner never dried properly. Our crews use camera inspection to locate the failure point precisely - we don’t guess. One repair near Burke Road last year involved a converted garage run that had collapsed at the first elbow; the interior was coated with that greasy dark film our technicians recognize immediately as refinery-corridor residue, not household dust.
Metal Duct Repair
Metal duct repair in Pasadena ranges from $180 for spot welding at a separated seam to $740 for rebuilding a plenum or transition box in a multi-system ranch. Metal holds up better than fiberglass board in Pasadena’s humidity, but the refinery particulate still bonds to galvanized interiors and accelerates corrosion at joints where condensation collects. We cut out failed sections, fabricate replacements on-site, and seal with mastic rated for the temperature range. Every repair is photographed before, during, and after.
Duct Insulation
Duct insulation in Pasadena runs $340-$620 per system for wrapping accessible metal or flex runs with formaldehyde-free fiberglass or closed-cell foam, depending on R-value and whether the ducts pass through an unconditioned attic or crawl space. Pasadena’s minimal elevation and standing-water retention after Gulf storms mean ducts in exterior walls or soffits stay wet longer than in higher suburbs. Proper insulation with a vapor barrier slows the condensation that feeds mold growth inside the system. We specify the material in writing before starting.

BeforeAfterTrusted Brands We Service in Pasadena
Our trucks stock parts and materials from Honeywell, Aprilaire, and Guardsman - brands Pasadena homeowners can verify independently before agreeing to any work. We don’t use generic sealants or unmarked insulation; the mastic and tape we apply carry manufacturer ratings for temperature and pressure, and we note the specific product on the written scope. For duct repair jobs requiring new flex duct or metal transitions, we source Nikro and Rotobrush-compatible materials with documented fire and mold-resistance ratings. Fast turnaround matters in a market where failed ductwork can leave a family without cooling for days in July; our Houston office maintains inventory for same-week Pasadena jobs rather than ordering parts after the first visit.
Common Duct Repair & Sealing Problems We See in Pasadena Homes
- Delaminated fiberglass duct board at seams. Original 1950s-1980s duct board near Richey Street separates along the joints after decades of 90%-plus humidity. The leaks aren’t visible from the register; they require camera inspection to locate and mastic sealing to repair.
- Post-Harvey mold in lower duct runs. Floodwater absorbed into slab-home ductwork in 2017, and surface vacuuming doesn’t reach the liner contamination. Without agitation tools and HEPA negative-pressure extraction, mold returns within one cooling season.
- Greasy refinery-corridor particulate binding to duct interiors. Technicians working older neighborhoods near Burke Road find a dark, oily film that standard shop-vac passes redistribute rather than remove. HEPA filtration and source-removal agitation are required.
- Collapsed flex duct in converted garage additions. Third-system garage conversions in Pasadena ranches often used undersized flex duct never rated for the heat load. The run collapses at elbows, restricts airflow, and trips the air handler on high demand.
Pricing for Duct Repair & Sealing in Pasadena, TX
Here’s what duct repair and sealing actually costs in Pasadena’s market:
| Service | Price Range (Per System) |
|---|---|
| Duct sealing with mastic (accessible joints) | $280-$450 |

| Metal duct repair (spot to rebuild) | $180-$740 |
| Duct insulation (wrap or replace) | $340-$620 |
| Camera inspection with photo documentation | Included on every job |
Three factors push Pasadena jobs toward the higher end: multiple systems requiring separate access and isolation, post-Harvey contamination requiring source removal before sealing, and refinery-corridor particulate buildup demanding agitation tools beyond standard vacuuming. We price per system, not per vent, and we deliver that price in writing before any work begins - Haven Standard Clause 1. No exceptions. Call (346) 253-1822 for a written estimate; estimates are free.

FAQs - Duct Repair & Sealing in Pasadena
Yes. Each air handler and its associated duct runs are priced as a separate system. In Pasadena’s slab-on-grade ranches near Burke Road and Richey Street, three separate systems - main house, primary addition, converted garage - are common, and a flat whole-home rate would either overcharge you for small systems or under-scope the work on larger ones. We inspect and price each independently. Call (346) 253-1822 to schedule a per-system evaluation.
That’s refinery-corridor particulate - hydrocarbon residue and sulfur compounds from the Houston Ship Channel’s industrial density that don’t occur in suburbs like Pearland or Friendswood. The film binds to duct interiors and resists standard vacuuming. Our crews use Rotobrush agitation with HEPA negative-pressure extraction to remove it, then document the cleaned surface with before-and-after photos. If your home is near Burke Road or Richey Street, this contamination is nearly universal in original ductwork.
Yes, on every job. Camera inspection locates leaks, delamination, and contamination before we quote; after sealing, we photograph the completed joints and record static-pressure readings at the registers. The Documented Photo Record is delivered as a standard deliverable, not an extra. Haven Standard Clause 4 requires verifiable documentation - you should never pay for duct work you cannot inspect yourself.
Camera inspection shows whether floodwater reached the liner. If the fiberglass duct board is stained, compressed, or growing mold at the interior surface, sealing over it traps contamination and it’ll return within one cooling season. We recommend full replacement of flood-affected runs, with sealing reserved for structurally sound ductwork with intact liners. Our written scope specifies which runs get which treatment, with photos to justify the recommendation. Call (346) 253-1822 for a free second opinion on any other company’s estimate.
Pasadena’s refinery-corridor air and high humidity demand MERV 11-13 pleated filtration at minimum, with a 4-inch media cabinet if the air handler can accommodate the static pressure. Higher MERV without proper duct sealing actually worsens leaks by increasing negative pressure at joints. We sequence the work: seal first, then upgrade filtration, then verify the system isn’t pulling unfiltered air through remaining gaps. Aprilaire and Honeywell media filters are what we typically specify for Pasadena’s contamination load.
