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.
Dryer Vent Inspection in Lewisville, TX
A dryer vent inspection in Lewisville, TX typically runs $79-$149 and takes 45 to 75 minutes from arrival to written report. The inspection uses a flexible camera to document what’s inside the vent run – lint accumulation, crushed or kinked sections, disconnected joints, and any bird or pest nesting that has blocked airflow at the termination point. If you’re not sure whether your dryer vent needs Dryer Vent Cleaning services or repair, the inspection answers that question with photographs, not guesses.
At CleanRun Air Duct Cleaning Lewisville, inspection work is part of every dryer vent job we do – but it’s also available as a standalone service. If a technician from another company quoted you a cleaning without ever looking inside the vent first, that’s worth a second look. Our Dryer Vent Cleaning in Lewisville page explains the full cleaning process; this page covers the inspection specifically: what we look for, what you receive, and what it costs.
Every inspection includes a written price before we start, a camera-documented photo record of the vent interior, and a plain-language written summary of findings. Tomas Reyes built CleanRun on that model in 2013, and it hasn’t changed across more than 52,000 jobs since. Call (940) 240-8552 – a live person will answer.
When You Need a Dryer Vent Inspection
Some of these situations are obvious. A few are easy to miss until something fails. If any of the following apply to your home in Lewisville, an inspection gives you a documented baseline to work from.
- Clothes take more than one cycle to dry. A full drying cycle on a properly vented gas or electric dryer should finish in 35 to 45 minutes. If towels or jeans are still damp after a full cycle, restricted airflow inside the duct run is almost always the cause – not the dryer itself.
- The exterior vent flap stays closed during operation. Stand outside while your dryer runs and watch the wall cap or roof cap. The flap should open visibly. If it barely moves or stays shut, something is blocking the duct from the inside – lint compaction, a crushed flex section, or a nest at the termination point.
- The dryer cabinet feels hot to the touch. Surface heat on the front panel or top of the unit is a sign that exhaust heat has nowhere to go. In Lewisville’s summers, when ambient attic temps already push past 130°F, a blocked vent in an attic duct run creates conditions that warrant immediate inspection.
- You haven’t had the vent inspected in more than two years. The National Fire Protection Association (NFPA 211) recommends annual dryer vent inspection and cleaning. Many Lewisville homes built between 2005 and 2018 in subdivisions like Oakmont, Castle Hills, and Vista Ridge have long duct runs – often 15 to 25 feet with two or three elbows – that accumulate lint faster than shorter straight runs.
- You’ve had a technician “clean” the vent with a shop vac and a brush only. That process removes surface lint from accessible sections but misses compacted debris at elbows and any structural issues in the duct. An inspection after that type of service frequently reveals that the vent wasn’t cleared past the first bend.
- Your home recently had a bird or squirrel nest near the exterior vent cap. Lewisville sits in the eastern Cross Timbers transition zone, and European starlings and house sparrows regularly nest in low-profile dryer vent caps, particularly in spring. A nest doesn’t have to fully block the duct to create a fire hazard – a partial blockage traps lint against a heat source.
Our Dryer Vent Inspection Process

Every step below is the same whether we’re inspecting a single-story ranch in The Legends or a two-story backing up to Lake Lewisville with an attic duct run. The process is repeatable because the documentation standard doesn’t change by job size.
- Written scope and price before any work starts. Haven Standard Clause 1 means you receive a written price covering the inspection, the camera documentation, and the written findings report – before the first panel comes off. No “we’ll tell you after we look” pricing. The number is on paper, and you confirm it before we proceed.
- Exterior termination point assessment. The technician inspects the wall cap, soffit cap, or roof cap from outside the home first. We document the flap condition, check for pest or bird nesting material, measure the opening size against manufacturer specifications, and photograph the exterior before touching anything indoors. In Lewisville, we see louvered caps on a significant number of homes built before 2010 – these are no longer code-compliant for dryer vent termination and will be noted in the report.
- Interior duct run camera inspection. A flexible camera is fed through the full length of the duct run – from the dryer connection point to the termination – capturing still images at each elbow, joint, and transition. We use professional-grade inspection equipment calibrated for duct work so we can document a 3-inch lint accumulation at a specific elbow rather than telling you “there’s some buildup in there.” Images are timestamped and saved as part of your Documented Photo Record.
- Airflow measurement at termination. We measure airflow velocity at the exterior cap using an anemometer. This gives us a baseline number that we document in the findings report. If cleaning is performed afterward, we measure again and record both numbers – so you can see the actual difference in airflow, not just a before-and-after photo of lint.
- Duct run structural assessment. The camera inspection also documents duct material, joint condition, and duct routing. Flex duct with tight bends – common in Lewisville homes where the laundry room was added as part of a floor plan revision – restricts airflow independent of lint levels. Disconnected joints that vent exhaust into a wall cavity or attic space are flagged separately because they require duct repair, not cleaning.
- Written findings report delivered at job completion. Before we leave, you receive a written summary of every finding, the camera images, the airflow measurements, and a plain-language description of recommended next steps – with associated prices written out for each option. You decide what to do with that information. We don’t pressure, and we don’t invent problems that the camera didn’t show.

AfterDryer Vent Inspection Pricing in Lewisville
Dryer vent inspection in Lewisville costs $79-$149 as a standalone service. The range reflects differences in duct run length, access complexity, and whether the termination point requires roof access versus a standard wall cap. Below is how the pricing breaks down.
| Inspection Scenario | Typical Price Range |
|---|---|
| Standard single-story, wall-cap termination, duct run under 15 ft | $79-$99 |
| Two-story or attic-routed duct run, 15-25 ft with 2-3 elbows | $99-$129 |
| Complex routing, roof termination, or duct run over 25 ft | $129-$149 |
| Inspection bundled with full dryer vent cleaning (same visit) | Inspection cost absorbed into cleaning price – see cleaning page for bundled range |
A few notes on what affects where your job falls in that range. Lewisville homes in the Castle Hills area frequently have laundry rooms positioned on an interior wall, which means the duct run travels horizontally through a floor cavity before turning up through the attic and out the roof. That routing adds both length and elbow count, which puts those jobs in the middle to upper end of the range. Newer construction in the Vista Ridge corridor tends to have shorter, more direct runs, usually in the lower tier.
If you have a written estimate from another company, bring it. CleanRun’s Free Second Opinion puts our written price next to theirs – no charge for the comparison. Call (940) 240-8552 to schedule; written price is confirmed before we arrive, not after.
What the Findings Report Includes

The written findings report you receive at the end of every inspection is a concrete deliverable, not a verbal summary. It covers:
- Camera images of the duct interior, labeled by location (connection point, first elbow, second elbow, transition to rigid, termination approach)
- Airflow velocity measurement at the exterior cap, recorded in feet per minute
- Duct material identification (rigid metal, semi-rigid aluminum, vinyl flex, or foil flex) and any code concerns specific to Lewisville building standards
- Joint condition: whether all joints are mechanically connected and sealed
- Exterior cap type, flap condition, and pest or nesting debris
- Recommended next steps with written price for each option
That document is yours. It’s useful if you ever sell the home, file an insurance claim related to a dryer fire, or want a baseline for the next inspection. No other company serving Lewisville has committed to this level of documentation as a standard deliverable on every visit – CleanRun has done it since 2013 because it’s the only way to stand behind a 365-Day Done Right Promise in writing.
Why Dryer Vent Inspection Is a Separate Step – Not an Add-On
The Vent Cleaning industry has a pattern: sell a discounted cleaning, arrive with a brush and a shop vac, and leave without documenting what was actually inside the duct. The customer’s dryer runs a little faster for a few months, and nobody knows whether the real problem – a crushed flex section at the back of the dryer, a disconnected joint venting into the wall, a compacted lint plug at an elbow 18 feet in – was ever addressed.
Inspection is the step that separates cleaning from documented cleaning. When our camera shows a 4-inch lint accumulation at the second elbow of a duct run in a home in The Legends, we photograph it before we touch it. When we clean that section, we photograph it again. The before-and-after images go into your Documented Photo Record. That record is what makes the 365-Day Done Right Promise mean something – because if the problem recurs within a year, there’s a paper trail showing exactly what was done and when.
This is also why we don’t clean a vent without inspecting it first. The full dryer vent service – inspection through cleaning through post-cleaning airflow measurement – is documented end to end. If you’re looking at the full service, the home page explains how CleanRun’s standard applies across every service we offer.
Dryer Vent Codes and Permit Requirements in Lewisville

Lewisville follows the International Residential Code (IRC) as adopted by the State of Texas, with local amendments enforced by the City of Lewisville Development Services Department. For dryer vents specifically, IRC Section M1502 requires:
- Maximum duct run of 35 feet from dryer to termination, reduced by 5 feet for each 90-degree elbow and 2.5 feet for each 45-degree elbow (some dryer manufacturers specify shorter maximums – those govern when more restrictive)
- Rigid or semi-rigid metal duct only – vinyl flex and foil accordion flex are not code-compliant for dryer exhaust in Lewisville
- Termination at an exterior wall or roof with a backdraft damper (flap cap), not a louvered vent or screen that can trap lint
- Minimum duct diameter of 4 inches throughout the run
Dryer vent inspection or cleaning does not require a permit in Lewisville. Duct repair or replacement work that modifies the existing installation may trigger a mechanical permit depending on scope – our written findings report will note if we believe the condition warrants a permit conversation with Development Services. We don’t make that determination for you, but we document what we found so you have accurate information.
FAQs – Dryer Vent Inspection in Lewisville
How often should I have my dryer vent inspected in Lewisville?
Annual inspection is the standard recommended by NFPA 211, and it’s what we recommend for most Lewisville homes. Homes with longer duct runs – particularly in Castle Hills, Oakmont, or newer subdivisions with attic-routed vents – or households that run the dryer daily may benefit from inspection every 6 to 8 months. A single inspection establishes your baseline; the camera images from that visit tell you whether your duct accumulates lint faster than average, which is the clearest guide to your personal cleaning interval. Call (940) 240-8552 and we’ll give you a written estimate before we schedule.
Is it cheaper to get the inspection and cleaning done at the same time?
Yes. When inspection and cleaning happen on the same visit, the inspection cost is absorbed into the cleaning price rather than billed separately. The full dryer vent cleaning service – camera inspection, cleaning, and post-cleaning airflow measurement – runs $149-$279 in Lewisville depending on duct run length and access. For details on pricing, see our guide on How Much Does Dryer Vent Cleaning Cost? (2026 Price Guide) - Lewisville, TX. Scheduling them separately costs more total. If you already know the vent needs cleaning, the bundled service is the practical choice. Call (940) 240-8552 for a written price specific to your home’s configuration.
Can a dryer vent inspection tell me if my vent is a fire risk?
The inspection documents what the camera finds: lint accumulation levels, duct material type, joint integrity, airflow restriction, and termination condition. We describe what we found – a specific measurement, a specific location, a specific material – and we note when a finding falls outside code requirements or manufacturer specifications. Whether a particular condition constitutes an imminent fire risk is a determination you should make with that documented evidence in hand. What we can say is that a duct run with crushed flex, a compacted lint plug at an elbow, and a non-functioning termination flap has all three conditions associated with dryer fires documented in NFPA data. The camera shows you what’s there. Call (940) 240-8552 to schedule an inspection and get those answers in writing.
Do you inspect dryer vents in multi-story homes with roof terminations in Lewisville?
Yes. Roof-termination inspections are common in two-story Lewisville homes where the laundry room sits on the second floor or where the duct was routed through the attic during original construction. The inspection process is the same – camera through the full run, airflow measurement at the termination – but roof access adds to the time and falls in the $129-$149 range. The written findings report covers the roof cap condition, which in Lewisville can include wind damage to the cap housing itself, a separate issue from lint accumulation. Call (940) 240-8552 for a written price before we arrive.
