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.

AfterDryer Vent Inspection in Alexandria, VA
A dryer vent inspection in Alexandria typically runs $79-$149, takes 45 to 75 minutes, and produces a written report with photographs of the duct interior before any cleaning or repair work is discussed. If you’ve noticed your dryer running longer than one cycle to dry a normal load, or the exterior wall cap feels unusually hot to the touch, that’s the duct telling you something – and the only way to know exactly what is to put a camera inside it.
At CleanRun Air Duct Cleaning Alexandria, every inspection starts with a written price before a single panel comes off the wall. That’s not a policy we revisit on a case-by-case basis – it’s Haven Standard Clause 1, and it applies to every job Tomas Reyes and our crew show up to. After the inspection, you receive a documented photo record of what the camera found: the actual debris buildup at each elbow, the condition of the duct liner, and the airflow reading at the termination cap. If you want to understand what’s happening inside your dryer vent line before agreeing to any Dryer Vent Cleaning services, call us at (240) 318-7712.
This page covers what a dryer vent inspection includes, what conditions prompt one, how we price it, and what the photo record looks like when we leave. For the full scope of cleaning services, see our Dryer Vent Cleaning in Alexandria page.
When You Need a Dryer Vent Inspection
Some of these signs are obvious. Others are easy to rationalize away until the duct is blocked enough to cause a problem. In Alexandria – particularly in the older townhomes along Seminary Road, the row houses in Del Ray, and the condo buildings near King Street Metro – vent lines are often longer, have more elbows, and were installed at a time when flexible plastic ductwork was standard. That combination accelerates lint accumulation and makes inspection more urgent, not less.
- Drying times have crept past one full cycle. A load that took 45 minutes two years ago now takes 75 or needs a second run. That’s airflow restriction – lint is compressing in the duct and the dryer is working against itself.
- The laundry room feels noticeably warmer than the rest of the house. If the exhaust isn’t moving freely out of the building, the heat has to go somewhere. It goes into the room. In Alexandria’s humid summers, that extra heat load also adds to your cooling bill.
- The exterior wall cap doesn’t open fully when the dryer is running. The flapper on your termination cap should open wide under normal airflow. If it’s barely cracked, the duct is either blocked or crimped somewhere along the run.
- You haven’t had the vent cleaned or inspected in more than 12 months. The U.S. Fire Administration recommends annual cleaning. In Alexandria’s older housing stock – where duct runs sometimes travel through finished walls and multiple floors before reaching an exterior cap – 12 months is a reasonable maximum, not a conservative suggestion.
- Your dryer is running hot enough to trip the thermal fuse, or the machine is shutting itself off mid-cycle. Modern dryers have high-limit thermostats that cut power when exhaust temperatures exceed safe thresholds. If your dryer is cutting out, a blocked vent is the first place to look before replacing any parts.
- You’ve had recent HVAC or renovation work and the duct may have been disturbed. In Del Ray and Rosemont, we regularly find that renovation crews disconnect vent lines at the wall connection and don’t reconnect them securely. The lint then exhausts into the wall cavity instead of outside – which is a fire risk and a moisture problem simultaneously.
Our Dryer Vent Inspection Process
The inspection follows the same documented sequence on every job. We don’t adapt the process based on how the day is going or how straightforward the job looks from the outside – the camera goes in regardless, because what’s visible from the laundry room tells you almost nothing about what’s happening at the second elbow or behind the drywall.
- Pre-inspection airflow baseline. Before opening anything, we measure static pressure and airflow at the dryer connection point. This gives us a number to compare against after the inspection is complete – so you can see in writing whether airflow improved or whether the duct has a structural problem that cleaning alone won’t fix.
- Visual and camera inspection of the full duct run. Using a flexible camera – the same caliber of inspection tooling used by HVAC contractors, not a consumer-grade scope – we photograph the interior of the duct run from the dryer connection to the termination cap. Every elbow, every transition, every straight run gets documented. If there’s a crushed section, a disconnected joint, or a bird’s nest at the exterior cap (a situation we’ve found more than once in Alexandria’s older brick buildings), the camera shows it before we say a word about what needs to happen next.
- Lint depth measurement at accumulation points. Lint doesn’t distribute evenly. It collects at elbows, at low points in the run, and at any point where the duct diameter narrows due to crimping. We measure and record the depth of accumulation at each of these points. A 3-inch lint pack at the first elbow is a specific finding. “Your vent was pretty dirty” is not.
- Termination cap inspection. The exterior wall cap or roof cap is the most commonly neglected part of the system. We check that the flapper opens freely, that there’s no pest intrusion, and that the cap itself is the correct type for a dryer termination – not a standard 4-inch HVAC vent cap, which doesn’t have the correct flapper geometry to handle dryer exhaust volume.
- Written findings report with photographs. Before we leave, you have a written summary of every finding and a set of photographs matched to each location in the duct run. If cleaning is needed, the written price for that work is attached to the same document. If there’s a duct repair required – a crushed section, a disconnected joint, a material replacement from plastic to rigid aluminum – that scope and price is written out separately, so you can decide on each item independently.
- Post-service airflow confirmation (if cleaning or repair follows the inspection). If you proceed with cleaning or repair on the same visit, we take a second airflow reading at the end and include it in the job record. The before and after numbers are yours to keep. That’s what the 365-Day Done Right Promise is built on: documented evidence, not our word for it.
BeforeAfterDryer Vent Inspection Pricing in Alexandria
Vent Cleaning inspection in Alexandria costs $79-$149 for most single-family homes and townhomes. Condominiums and multi-story homes with longer duct runs, additional elbows, or rooftop termination caps typically fall in the upper portion of that range. The written price is confirmed before the job starts – every time, without exception, under Haven Standard Clause 1.
| Scenario | Typical Price Range |
|---|---|
| Standard townhome or single-family, wall termination, run under 15 ft | $79 - $99 |
| Longer run (15-25 ft), 2-3 elbows, standard wall cap | $99 - $129 |
| Condo unit with shared or rooftop termination, extended run | $119 - $149 |
| Inspection bundled with dryer vent cleaning on the same visit | Cleaning price includes inspection; no separate inspection fee |
A few things that affect where your job lands in that range:
- Duct run length. Longer runs require more camera time and more thorough airflow baseline documentation. Runs over 25 feet – which appear in some of Alexandria’s taller condo buildings near Potomac Yard and Eisenhower Avenue – are quoted at the high end.
- Number of elbows. Each 90-degree elbow is equivalent to several additional feet of straight duct in terms of airflow resistance. More elbows mean more inspection points and more photographs in the record.
- Termination cap type and location. A roof-mounted termination requires a ladder and additional inspection time. Wall caps on the first or second floor are straightforward.
- Inspection-only vs. inspection plus cleaning. If cleaning is needed and you want to proceed on the same visit, the inspection documentation is included in the cleaning price – you don’t pay twice.

What the Photo Record Shows
A documented photo record isn’t a marketing gesture. It’s the thing that separates a real inspection from a technician telling you your vent “looked pretty blocked” and handing you an invoice. Every CleanRun inspection produces a set of photographs keyed to specific locations in the duct run: the connection at the dryer, each elbow, any straight run where accumulation was measured, and the termination cap interior and exterior.
In Alexandria’s Del Ray and Rosemont neighborhoods, where a large number of the homes were built between 1940 and 1975 and have had their laundry rooms relocated at least once, we frequently find duct configurations that were improvised rather than designed. The camera has shown us duct runs that terminate into the wall cavity instead of outside, flexible plastic ductwork still in place behind drywall that was never replaced during a renovation, and exterior caps that were painted shut at some point and haven’t opened in years. None of that is visible from the laundry room. All of it shows up in the photo record.
The photographs are delivered as part of the written job record before we leave the property. If the inspection is followed by cleaning, you receive before-and-after photographs for every section of the run. That record is yours – not something we hold in a customer portal that expires after 90 days.
Alexandria-Specific Conditions That Affect Dryer Vent Inspections
Alexandria’s housing stock is more varied than most Northern Virginia cities its size. The older sections – Old Town, Del Ray, Arlandria, and Rosemont – have homes built across seven or eight decades, often with ductwork that was added after construction rather than designed into the building. The newer sections near Potomac Yard and Carlyle have high-rise and mid-rise condo construction where dryer vent runs can travel 30 or 40 feet through shared walls and mechanical chases before reaching a termination point.
Alexandria’s climate adds its own variable. The city sits in a humid subtropical zone – hot, humid summers and cold winters with occasional ice accumulation on exterior surfaces. Ice buildup at a termination cap can temporarily block the flapper in winter, which forces dryer exhaust back into the duct and accelerates lint accumulation at the nearest elbow. We see this pattern in Alexandria homes every February and March, particularly in units with north-facing or shaded exterior walls.
Pest intrusion is a consistent finding in Alexandria’s brick row houses and older colonial-style homes. Birds, squirrels, and occasionally wasps use dryer vent termination caps as entry points, particularly caps that haven’t been inspected in several years. A blocked or partially obstructed termination cap from a nest isn’t always visible from outside – the camera shows what’s actually there.
Safety Note on Dryer Vent Conditions
A blocked dryer vent is a documented fire hazard. The National Fire Protection Association attributes thousands of residential fires annually to clothes dryer venting issues, and lint – which is highly combustible – is the primary fuel source. This is worth stating plainly: if your dryer is running hot, shutting off mid-cycle, or hasn’t been inspected in more than a year, have it looked at before the next load. The inspection itself is low-risk and non-invasive. Waiting is not.
Do not attempt to inspect or clear a dryer vent run that travels through finished walls or multiple floors without proper equipment. Disconnecting duct sections improperly can leave lint in the wall cavity, and reassembling flexible ductwork incorrectly creates crimping that compounds the original restriction. If the duct run is more than 10 feet or involves more than one elbow, the inspection is a job for someone with a camera and calibrated airflow measurement tools – not a shop vac and a flashlight.
FAQs – Dryer Vent Inspection in Alexandria
How much does a dryer vent inspection cost in Alexandria, VA?
A dryer vent inspection in Alexandria costs $79-$149, depending on duct run length, number of elbows, and termination cap location. The written price is confirmed before any work starts – that’s Haven Standard Clause 1, applied on every job without exception. If you proceed with cleaning on the same visit, the inspection documentation is included in the cleaning price; there’s no separate inspection charge on top. See How Much Does Dryer Vent Cleaning Cost? (2026 Price Guide) - Alexandria, VA for full pricing details. Call (240) 318-7712 for your written quote – all calls are answered by a live person.
How long does a dryer vent inspection take?
Most dryer vent inspections in Alexandria take 45 to 75 minutes. A standard townhome or single-family home with a wall termination and a run under 15 feet is typically done in 45 minutes. Longer runs, rooftop terminations, or condo units with extended duct paths through mechanical chases can take closer to 75 minutes. The time includes the baseline airflow measurement, the full camera pass, lint depth documentation at accumulation points, and delivery of the written findings report before we leave.
Can a dryer vent inspection find problems that cleaning alone won’t fix?
Yes – and this is exactly why the inspection comes before any cleaning recommendation. The camera regularly finds conditions that require duct repair or replacement rather than cleaning: crushed or kinked sections in the duct run that restrict airflow regardless of how clean the duct is, disconnected joints exhausting into wall cavities, plastic flexible ductwork that should be replaced with rigid aluminum, and termination caps that are the wrong type for dryer exhaust. In Alexandria, we find these structural issues in roughly one in four inspections on older housing stock. Cleaning a crushed duct doesn’t uncrimp it. The inspection identifies which problem you actually have before any money changes hands for the solution.
Do I need a dryer vent inspection if my dryer seems to be working fine?
A dryer that appears to be working normally can still have a duct that’s 60-70% restricted. Dryers compensate for airflow restriction by running longer and hotter – you notice the efficiency drop before you notice anything that feels like a warning sign. The NFPA recommends annual inspections regardless of how the dryer seems to be performing. In Alexandria’s older housing stock, where vent runs are frequently longer than current code recommends and may include materials that are no longer considered safe for dryer termination, annual inspection is the reasonable minimum – not a conservative precaution.
