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 Dryer Vent Cleaning Across Leon Valley
Dryer vent cleaning in Leon Valley typically costs $140-$280 for a standard single-family ranch home, with vent rerouting or cap replacement adding $85-$195 depending on material and access. Most jobs are scheduled within 2-4 business days, and every appointment starts with a written price before any work begins.
We serve Leon Valley’s Bandera Road corridor, the neighborhoods near Leon Valley Elementary, and the postwar ranch tracts that make up nearly the entire residential stock of this city. Our crews know what they’re walking into: original 1960s flexible foil ductwork, under-house terminations that were code-legal when poured but are now packed with decades of lint, and attic runs that have spent fifty summers in 150°F heat. Dispatch and scheduling are coordinated from our San Antonio office, but the technicians who arrive at your door serve Leon Valley homes regularly enough to recognize the construction patterns without pulling a panel. If your dryer has started taking two cycles to finish a load, or if you’ve noticed lint collecting behind the machine where it shouldn’t, call (726) 600-7155 for a free estimate with a written price delivered before we touch a tool.
Why CleanRun Air Duct Cleaning San Antonio Is Leon Valley’s Preferred Dryer Vent Cleaning Company
We’ve been in Leon Valley homes since 2013, and the photo records from those jobs tell a consistent story. The 1950s-1970s ranch homes that dominate this market - the ones off Bandera Road, near Huebner Road, and throughout the neighborhoods feeding into Leon Valley Elementary - were built with dryer vent configurations that are now obsolete and, in many cases, hazardous. Our Dryer Vent Cleaning team documents every run with before-and-after photography, and those images are delivered to the homeowner as part of the standard job record. No manager approval needed. No “trust us” required.
Our reputation in Leon Valley is built on what we can show, not what we claim. The 365-Day Done Right Promise applies to every job, backed in writing on every invoice - Haven Standard Clause 1. Technicians are background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3: Verified Crews. We don’t do urgency theatre or coupon pricing. We do written prices, documented results, and accountability after the truck leaves.
Our Dryer Vent Cleaning Services in Leon Valley
Dryer Vent Inspection
Every Leon Valley job starts here. We run a camera through the full vent run, from the back of the dryer to the termination point, and the homeowner sees what we see in real time. In Leon Valley’s older ranch homes, we’re frequently finding original flexible foil duct that has degraded in attic heat, crushed transitions through joist bays, or terminations that dump into the crawl space instead of outside air. The inspection produces a written scope with a fixed price before any cleaning or repair begins. No exceptions.
Vent Cleaning and Lint Removal
For intact vent runs with normal accumulation, we use Rotobrush agitation tools combined with negative-pressure extraction (vacuum suction that pulls dislodged debris out of the duct rather than pushing it deeper) to clear the full run. In Leon Valley, the lint loads are often heavier than expected because original foil ducts have rough interior surfaces that snag fibers, and because the same northwest winter winds that carry cedar pollen also drive fine limestone dust into laundry room intakes. The camera confirms the run is clear before we pack up. Photos included.
Vent Rerouting
This is where Leon Valley’s housing stock really shows its age. Original dryer vents that terminate under the house or through uninsulated attic runs are not just inefficient - they’re a fire hazard and a source of moisture damage. We reroute to code-compliant exterior terminations using rigid aluminum pipe, which won’t crush, won’t degrade in attic heat, and won’t become a lint trap at every joint. A typical reroute in a Leon Valley ranch home runs $180-$340 depending on linear footage and access.
Vent Cap Replacement and Bird Guard Installation
Leon Valley’s proximity to the Hill Country means wildlife pressure on exterior vent terminations. We replace damaged or missing caps with new Guardsman bird guards that block entry without restricting airflow. Standard cap replacement is $85-$145; bird guard installation on a new or existing termination is $110-$165.

Common Dryer Vent Cleaning Problems We See in Leon Valley Homes
- Crushed foil runs in attic joist bays. The original flexible foil duct installed in Leon Valley’s 1960s and 1970s ranches was never meant to withstand decades of compression between joists. We regularly find runs flattened to half their diameter, with lint packed solid behind the wall where the homeowner can’t see it.
- Under-house terminations that backdraft in winter. Crawl space vent exits were common in this construction era. When northwest winds hit Leon Valley in January, they force moist exhaust back into the laundry room - and during Cedar Fever season, that same backdraft pulls pollen and crawl space air into the house.
- Fiberglass duct board delamination in shared joist bays. When a dryer vent shares a bay with an aging HVAC return, degraded fiberglass from the nearby duct board gets caught in the lint screen. Homeowners think they need a new dryer; what they need is a camera inspection to find the real restriction.
- Original caps missing or degraded. Fifty years of sun and hail on a plastic vent cap ends the same way every time. Birds, wasps, and rodents move in. The dryer works harder. The electric bill climbs. We find it on inspection, show the photo, and fix it with a permanent metal solution.

These are whole-system prices, not per-foot or per-vent teaser rates that balloon once the van is in your driveway. Every price is written and agreed before work starts - Haven Standard Clause 1. What moves a Leon Valley job toward the higher end: rerouting through finished spaces, multiple story heights, or the need to cut access in drywall to reach a crushed run. What doesn’t change the price: finding more lint than expected. The written scope covers the full job, not just what we guessed from the driveway.

FAQs - Dryer Vent Cleaning in Leon Valley
Because the original flexible foil duct behind your wall is likely crushed, disconnected, or packed with lint - a failure mode we see in most 1960s-1970s Leon Valley ranches. The foil degrades in attic heat, tears at joints, and creates restrictions that the lint screen alone can’t compensate for. A camera inspection will show exactly where the blockage is. Call (726) 600-7155 for a free estimate with a written price before any work starts.
Leon Valley sits closer to the Hill Country cedar brakes than neighborhoods on San Antonio’s east or south sides, so northwest winter winds deliver heavier Ashe juniper pollen loads here. That pollen accumulates in laundry room air intakes and mixes with lint, forming denser blockages. If your vent is already restricted, Cedar Fever season makes the problem worse faster. We inspect and clear these mixed loads regularly from January through March.
It was normal for the construction era, but it is not normal by current code and it is not safe long-term. Under-house terminations were standard in 1950s-1970s ranch construction here, and they turn crawl spaces into lint traps that backdraft moist air into the laundry room. We reroute these to exterior wall terminations as a standard service. The written price for your specific reroute is delivered after inspection, never before we see the access path.
Our process exceeds NADCA guidelines for dryer exhaust systems: camera verification of the full run, mechanical agitation with Rotobrush tools, negative-pressure extraction with Nikro equipment, and photographic documentation of before-and-after conditions on every job. The NADCA standard is a baseline; our photo record requirement and written 365-Day Done Right Promise go further. Ask to see sample documentation from a recent Leon Valley job - we provide it.
Every 12-18 months for active households, and immediately if drying times increase or lint appears behind the machine. Original 1970s foil duct in Leon Valley’s uninsulated attics has exceeded its design life; annual inspection catches degradation before it becomes a fire hazard or a moisture damage claim. The inspection itself is quick, non-invasive, and produces a written condition report with photos. Call (726) 600-7155 to schedule.
At a 1968 ranch off Bandera Road near Leon Valley Elementary, our tech pulled the dryer vent cap and found the original flexible foil duct was crushed flat where it transitioned through the attic joist bay - lint had packed the entire 14-foot run solid. We ran a camera inspection, used Rotobrush agitation tools to break up the packed lint, then rerouted the vent with rigid aluminum pipe and installed a new Guardsman bird guard. The customer’s dryer cycle time dropped from two loads per cycle to one. The photo record of that job is still in our files, and we can show you what we found before we quote what it takes to fix yours.
Leon Valley’s 1950s-1970s ranch homes were built with dryer vents terminating under the house in the crawl space or through uninsulated attic runs - code-legal at the time but now long lint-choked and prone to backdrafting into the laundry room during Cedar Fever season. Most homeowners don’t discover this until a camera inspection reveals a crushed or disconnected flex run behind the wall. That’s why we start every job with the camera, not the brush. You see what we see. You get a written price. Then you decide.
