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.

Why CleanRun Air Duct Cleaning Leander Is Pflugerville’s Preferred Duct Repair & Sealing Company
We’ve worked in Pflugerville homes since 2013, and the pattern is consistent: the city’s explosive growth produced thousands of large two-story tract homes in Blackhawk, Springbrook, and Avalon that are now hitting the 15-20-year mark with duct systems that have never been professionally inspected. Our reputation here is built on documentation, not promises. Every job receives a written price before work begins - Haven Standard Clause 1 - and concludes with a Documented Photo Record of every duct run, delivered to the customer as part of the standard job record.
Technicians are background-checked, uniformed, and identified by name before arrival - Haven Standard Clause 3: Verified Crews. The 365-Day Done Right Promise backs every repair in writing; if the work is not right, we make it right. Calls are answered by a live person, 24/7, and scheduling to Pflugerville neighborhoods typically runs next-day or within 48 hours for non-urgent repairs.

Our Duct Repair & Sealing Services in Pflugerville

Duct Sealing
Most Pflugerville homes we inspect - especially the 2,000-3,500 sq ft two-story plans in Blackhawk and Avalon - leak 20-30% of conditioned air through gaps at trunk takeoffs, plenum connections, and register boots. Our duct sealing service uses mastic sealant and metal-backed tape on every accessible joint, then verifies with a pressure test where appropriate. In newer homes near active construction along SH 130, sealing also blocks the return-air chases that pull jobsite debris into the system. Typical duct sealing in Pflugerville runs $350-$650 for a full system.

Flex Duct Repair
The flex duct runs common in Pflugerville’s 2000s-era builds collapse, kink, or disconnect entirely in attic heat - particularly in original-Pflugerville homes along FM 685 and Pecan Street where the material is aging past 15 years. We repair or replace individual runs without tearing out the whole system, reconnecting at the plenum with proper supports and sealed collars. A single flex duct repair in Pflugerville typically costs $180-$340; multiple runs on a large two-story home can reach $500-$800.

Metal Duct Repair
Older metal ductwork in Pflugerville’s pre-2000 homes and some commercial applications develops rust, separated seams, and failed dampers. We patch or replace sections, re-seal with mastic, and insulate where the original wrap has degraded. Metal duct repair runs higher than flex - $400-$900 depending on accessibility and the extent of corrosion - but preserves systems that are otherwise structurally sound.

Duct Insulation
Uninsulated or degraded duct insulation in Pflugerville attics bleeds cooling efficiency for six months of the year. We install fresh fiberglass wrap or closed-cell sleeve insulation on exposed runs, particularly on the long trunk lines that serve multiple zones in Springbrook and Avalon’s larger floor plans. Duct insulation in Pflugerville typically runs $2.50-$4.50 per linear foot, with most residential jobs falling between $300-$600.

AfterTrusted Brands We Service in Pflugerville
Our equipment roster includes Rotobrush for mechanical agitation in residential duct runs, Nikro for negative-pressure extraction, and Honeywell and Aprilaire components for filtration and zoning upgrades. We stock common flex duct diameters, mastic sealant, and collar fittings locally, so most Pflugerville repairs don’t wait on parts. If your system uses Guardsman or Abatement Technologies components - common in newer Pflugerville builds with builder-grade installations - we carry those connections as well. Every brand we name is one you can look up independently; we don’t make performance claims beyond manufacturer specifications.
Common Duct Repair & Sealing Problems We See in Pflugerville Homes

- Construction debris in “new” homes. Homes in Blackhawk, Springbrook, and Avalon often start life with drywall dust and cellulose insulation already inside the ducts from handover. The builder’s rough clean doesn’t reach the trunk lines, and owners assume “new house, clean ducts” - which is rarely true in Pflugerville’s mid-buildout environment.
- Re-contamination from adjacent construction. Active buildout along SH 130 and Kelly Lane pumps fresh jobsite particulate into established homes through unsealed return-air chases and attic vents. We’ve found ducts re-coated with white drywall dust within two years of a professional cleaning.
- Hidden disconnects in long attic runs. The branching duct layouts in Pflugerville’s large two-story tract homes hide failed mastic joints and collapsed flex duct deep in the attic, where the leaks never reach a register but quietly bleed conditioned air and draw attic dust into the system.
- Cedar pollen loading during heating season. Central Texas’s mountain cedar (Ashe juniper) pollen peaks December through February, right when Pflugerville homeowners run heat constantly. The pollen accumulates in duct interiors and on filters, compounding any existing leaks that bypass filtration entirely.
Pricing for Duct Repair & Sealing in Pflugerville, TX

What moves a job toward the higher end: attic accessibility (steep pitch, blown-in insulation covering the runs), number of zones served, and whether we find construction debris requiring source-removal cleaning before sealing can be effective. Homes near active development - the SH 130 corridor, northern edges toward Cele Road - often need that pre-seal cleaning. Every estimate is free, written, and delivered before any panel comes off. Call (737) 252-1285.

FAQs - Duct Repair & Sealing in Pflugerville

Because live construction on adjacent lots feeds drywall dust and cellulose insulation fibers through your attic vents and unsealed return-air chases before the builder’s one-year warranty walk even ends. In Pflugerville’s mid-buildout areas - particularly near SH 130 and Cele Road - this jobsite-debris cycle is constant. We recommend a camera inspection at 6-12 months on any new build. Call (737) 252-1285 for a free estimate.
It’s usually both. The white dust is drywall particulate that entered through leaks in the return-air pathway; the repair is sealing those leaks with mastic so the debris stops entering, and the cleaning is removing what’s already inside. In Avalon’s two-story tract homes, we regularly find mastic gaps at trunk takeoffs plus flex duct coated in construction dust. We seal first, then clean under negative pressure with HEPA filtration. Call (737) 252-1285 - estimates are free.
Yes, in most cases. We can replace individual flex duct runs from the plenum to the register boot without disturbing the rest of the system. On original-Pflugerville homes, the flex is often 6-inch diameter - a standard size we stock - and the repair typically takes 2-3 hours. If the plenum itself is degraded, we’ll note that in the written estimate and let you decide. Call (737) 252-1285 for an exact quote.
Windborne drywall dust and cellulose fibers from active jobsites enter older homes through attic vents and any gaps in the return-air chase, re-coating duct interiors that were cleaned only a few years earlier. The flat Blackland Prairie terrain offers no topographic barrier. In Pflugerville, this means a 5-year-old cleaning can be compromised by a new phase breaking ground two streets over. Sealing the return chases and plenum connections is the most effective prevention. Call (737) 252-1285 to assess your system’s current condition.
Both, but the air quality improvement is often more noticeable in Pflugerville homes. Sealing with mastic closes the return-air leaks that pull attic dust, pollen, and - near construction sites - drywall particulate directly into your living space. The energy savings are real (typically 20-30% reduction in duct leakage), but customers more often comment that the registers stopped blowing dust and the rooms cooled evenly. Every sealing job includes before-and-after photos of the accessible joints so you can see what was closed. Call (737) 252-1285 for a written estimate.
