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.

AfterTrusted Dryer Vent Cleaning for San Antonio Homeowners
Dryer Vent Cleaning in San Antonio typically costs $120-$280 for a standard single-family home and takes 60-90 minutes from arrival to final airflow test. CleanRun Duct Repair & Cleaning has documented every dryer vent job with before-and-after photos since 2013, and we deliver a written price before any work starts under Haven Standard Clause 1. Call (726) 600-7155 for a free estimate with no obligation.
San Antonio’s hard water, limestone-heavy soil, and extended cooling season create conditions that accelerate lint compaction inside dryer vents. In neighborhoods like Alamo Heights and Castle Hills, we’ve found vents packed solid after just 18 months because of how local construction practices route ductwork through long horizontal runs across attics. Our crews use Rotobrush and Nikro equipment to remove built-up lint at the source, then photograph the interior so you can verify the work yourself. Every technician is background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3: Verified Crews.
What Our Dryer Vent Cleaning Service Includes
Dryer Vent Inspection
A proper Dryer Vent Inspection starts with airflow measurement at the exterior cap and a borescope camera run through the entire duct length. We document restriction points, corrosion, improper materials, and any evidence of previous fire damage. In Terrell Hills and Windcrest, we regularly find flexible foil transition ducts that violate current IRC codes, or vents routed through crawl spaces where they trap moisture against framing.
You’ll receive a written scope with photos before we quote any work. No exceptions. Haven Standard Clause 1 requires it.
Vent Cleaning
We clean the vent full run from dryer connection to exterior termination using negative-pressure extraction, a process that pulls dislodged debris backward through a sealed collection system rather than blowing it into your home. For San Antonio’s longer vent runs, common in 2015-2025 construction in Live Oak and Universal City, we deploy Rotobrush mechanical agitation to break up compacted lint that air alone won’t move.
The job concludes with a second airflow test and timestamped after photos. Our documented photo record shows the actual interior condition, not just the lint we collected.
Lint Removal
Lint accumulation is the leading cause of dryer fires nationwide, and San Antonio’s dry spring months create especially hazardous conditions when static electricity builds in packed ductwork. We remove lint from the transition duct, the main vent run, the exterior termination cap, and the dryer’s internal lint trap housing, a step many competitors skip.
In Kirby and Leon Valley, we’ve pulled out bird nests, construction debris from original build-out, and once a complete exterior cap buried under years of packed lint. The camera doesn’t lie about what was actually in there.
Vent Rerouting
Some San Antonio homes, particularly 1970s-1990s builds in Converse and Selma, have vents that exceed 35 feet in equivalent length or terminate in crawl spaces where condensation pools. When the inspection shows a fundamentally flawed route, we reroute to code-compliant termination with rigid metal duct, proper slope for drainage, and accessible cleanouts.
This is not a upsell. We photograph the problem, explain the IRC requirement, and quote the reroute separately so you can decide with full information. Haven Standard Clause 1 again: written price before work starts.
Bird Guard Installation
San Antonio’s bird population, grackles especially, treats uncapped vents as ready-made nesting cavities. A bird guard, properly specified, allows moist air to escape while blocking entry. We install Guardsman-rated vent terminations with integrated pest barriers, sized to your duct diameter and local wind load.
We do not recommend mesh screens, which clog with lint and create the exact fire hazard you’re trying to prevent. Our guards are designed for dryer exhaust specifically, not improvised from hardware-store parts.
Vent Cap Replacement
Exterior vent caps corrode, break their flappers, or get painted shut. In Helotes and the Hill Country fringe, we’ve found caps degraded by UV exposure within five years of installation. We replace with code-compliant caps that include backdraft dampers to prevent wind-driven infiltration, a real problem during San Antonio’s spring storm season.
Every replacement is photographed before and after, with the old cap shown in hand next to the new installation for clear documentation.

Brands We Service for Dryer Vent Cleaning
We’ve serviced and cleaned venting connected to dryers from every major manufacturer sold in San Antonio since 2013. For Whirlpool and Maytag units, common in the 2015-2020 build wave across Stone Oak and Cibolo Canyons, we stock OEM transition ducts and know the specific lint trap geometries that affect internal airflow. LG and Samsung vent configurations, with their rear-offset designs, require particular attention to transition duct kinking, a leading cause of premature lint buildup we’ve documented repeatedly in Alamo Heights remodels.
Whether you have a Speed Queen from a local appliance dealer, a Bosch from a builder upgrade package, or any other make, we can inspect, clean, and document the full vent system. The brand on the front matters less than the condition of what’s behind it.
BeforeAfterSigns You Need Dryer Vent Cleaning Right Now
- Clothes take more than one cycle to dry. This is the most common symptom we hear from San Antonio homeowners, and it means lint has restricted airflow to the point where moist air cannot escape efficiently. Your dryer is working harder, your energy bill is climbing, and the heating element is operating at temperatures the vent was not designed to handle.
- The dryer exterior or laundry room feels unusually hot. Restricted airflow forces hot, moist air back into the room instead of outside. In summer months in San Antonio, this adds load to your air conditioning and creates condensation on cool surfaces that can promote mold growth.
- You smell burning or scorched lint during operation. This is a genuine fire warning. Lint ignites at approximately 450°F, and a restricted dryer vent can push the heating element well above that threshold. If you notice this smell, stop using the dryer and call for inspection.
- Visible lint accumulation around the exterior vent cap. When lint escapes the cap, it means the interior is packed to capacity and back-pressure is forcing debris out the only opening available. We see this frequently in Windcrest and Live Oak where long horizontal runs compound the problem.
- It’s been over 12 months since your last cleaning. For households doing 5+ loads weekly, annual cleaning is preventive maintenance, not an abundance of caution. San Antonio’s dust and pollen load, combined with pet hair in many households, accelerates accumulation beyond what manufacturer guidelines assume.
Our Dryer Vent Cleaning Process - Step by Step
- 1
Arrival and setup. Our technician arrives in a marked vehicle, introduces themselves by name, and lays protective floor covering from the entry to your laundry area. We verify the dryer make and model, then shut off gas or electrical supply before disconnecting the transition duct.
- 2
Inspection and documentation. We run a borescope camera through the full vent length and take timestamped photos of restriction points, damage, or code violations. Airflow is measured in cubic feet per minute at the exterior cap. You see what we see before any work is proposed.
- 3
Written price delivery. Haven Standard Clause 1: we present a written scope and price for your approval. This includes the cleaning method, any necessary repairs or replacements, and the final documentation you’ll receive. No work begins until you approve in writing.
- 4
Mechanical cleaning with negative-pressure extraction. Using Rotobrush or Nikro equipment matched to your duct size and material, we agitate and extract lint from the entire run. The collection system is HEPA-contained, so no debris enters your home. We clean the transition duct, the main run, the termination cap, and the dryer’s internal lint trap housing.
- 5
Verification and documentation delivery. A second airflow test confirms restored performance. We reconnect your dryer, restore power or gas, and run a test cycle. You receive the complete photo record, the written scope, and the 365-Day Done Right Promise documentation before we leave.
How Much Does Dryer Vent Cleaning Cost in San Antonio?
A standard dryer vent cleaning in San Antonio runs $120-$180; see our Dryer Vent Cleaning cost guide for details for a single-story home with direct exterior termination and accessible ductwork. Homes in Castle Hills and Terrell Hills with second-floor laundry rooms, rooftop terminations, or long horizontal attic runs typically fall in the $180-$280 range because of additional access time and equipment requirements. Vent rerouting, when needed, is quoted separately after inspection and generally runs $340-$580 depending on materials and routing complexity.
Several factors move the price within these ranges: total equivalent duct length (including elbows), termination location (ground-level wall cap versus rooftop or crawl space), presence of improper materials requiring replacement (flexible foil or plastic duct), and accessibility issues in finished spaces. We do not charge per vent, per foot, or by time on site. One flat price per system, agreed in writing before work starts.
The most common overpayment we see is the $79 coupon that becomes a $400 invoice once the technician is in the home. Our price is our price. If the inspection reveals a condition that changes scope, we photograph it, explain it, and quote the revision separately. You approve every dollar before it is spent. Bring any competitor’s written estimate and we’ll provide a free second opinion under the H.A.V.E.N. Standard.
Every estimate is free and includes the full inspection and photo documentation, even if you choose not to proceed.

Frequently Asked Questions - Dryer Vent Cleaning in San Antonio
Dryer vent cleaning is the mechanical removal of lint and debris from the full exhaust path between your clothes dryer and the exterior termination cap. It matters because lint accumulation restricts airflow, forces your dryer to overheat, and causes approximately 2,900 residential fires annually according to U.S. Fire Administration data. CleanRun’s process includes photographing the interior before and after so you can verify the hazard was actually removed, not just discussed.
A standard cleaning takes 60-90 minutes from arrival to final test cycle, including the inspection, documentation, and cleanup. Complex jobs with rooftop access, long attic runs, or rerouting needs may extend to 2-3 hours. We quote time expectations with the written price so you can plan accordingly, not discover the schedule at arrival. Call (726) 600-7155 to book a specific window.
