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.

AfterVent Cleaning in Alexandria, VA
Dryer vent cleaning in Alexandria typically runs between $89 and $179 for a standard single-story run, and most jobs are completed in under 90 minutes with the vent fully cleared and photographed before the technician leaves. If your dryer is taking two cycles to dry a single load, or you can feel heat backing up near the wall behind the unit, the vent line is likely the cause – not the appliance.
At CleanRun Air Duct Cleaning Alexandria, vent cleaning is one of the most straightforward services we perform, and also one of the most consequential. We’ve been photographing the inside of vent runs since 2013, and the debris we find in Alexandria homes – lint compacted at the first elbow, bird nesting material pushed in from rooftop caps, and foil flex duct that has partially collapsed inside the wall cavity – is specific enough that a photo says more than a paragraph of copy. Every job starts with a written price delivered before any panel comes off. That’s Haven Standard Clause 1, and it applies without exception.
This page covers our vent cleaning process, what it costs in the Alexandria market, and how to read the signs that your vent line needs attention. For the full picture of what we do – including multi-vent systems, periscope transitions, and exterior cap inspection – visit our Dryer Vent Cleaning in Alexandria service page.

When You Need Vent Cleaning
The vent line between your dryer and the exterior cap collects lint on every cycle. That’s normal. The problem is rate of accumulation, which depends on your duct length, number of elbows, and how often you run the dryer. In Alexandria’s older row houses and 1960s-era split-levels – particularly in Rosemont, Del Ray, and Potomac Yard – we regularly find vent runs that were routed through exterior walls with three or four 90-degree turns to clear the floor joists. More turns mean more places for lint to catch and compress.
- Clothes taking two or more cycles to dry. A fully or partially blocked vent reduces airflow through the drum. The dryer runs longer and hotter, but the moisture has nowhere to go. If a full load of towels routinely needs a second cycle, the vent line is the first place to check – not the heating element.
- The exterior wall or cabinet behind the dryer is warm to the touch. Heat that can’t exhaust through the vent starts radiating back into the wall cavity and surrounding cabinetry. In a laundry closet, you may notice it as an unusual warmth when you open the door mid-cycle.
- Visible lint at the exterior cap. Some lint at the flap is normal. A thick mat of lint packing the louvers, or a cap that won’t open fully when the dryer runs, signals that the restriction is at the terminal end of the run.
- The dryer shuts off mid-cycle on its own. Most modern dryers have a thermal limiter that trips when the internal temperature exceeds a threshold. Repeated mid-cycle shutoffs are a thermal-safety response to a blocked exhaust path, not a dryer malfunction.
- You haven’t had the vent cleaned in over 12 months and run the dryer more than four times per week. The National Fire Protection Association recommends annual inspection and cleaning for residential dryer vents. Households with large families or frequent laundry cycles – common in the townhome clusters near Eisenhower Avenue and Van Dorn – often need cleaning every 9 months.
- You’ve found evidence of a bird nest at the cap. In Alexandria’s older neighborhoods, European starlings and house sparrows nest in dryer vent caps from late March through June. A nest can fully block exhaust flow before you notice any drying performance change. Nest material also presents a distinct fire risk because it is dry, compact, and positioned directly in the exhaust stream.
Our Vent Cleaning Process
We don’t adapt a generic air duct protocol to dryer vents. The equipment, the approach, and the documentation are specific to vent cleaning, and the steps below reflect what actually happens on a job in Alexandria – not a cleaned-up description of what could happen.
- Pre-job inspection and written price. Before anything is moved or disconnected, the technician assesses the vent run: where it enters the wall, what type of duct is behind the panel (rigid galvanized, semi-rigid aluminum, or foil flex), the approximate linear footage, and the number of bends visible at the transition. A written price is produced from that information and handed to you before work begins. Haven Standard Clause 1 – no work starts without your signed acceptance of the written scope and price.
- Disconnect and pre-clean camera pass. The dryer is moved away from the wall and the transition duct – the short flexible section connecting the dryer to the wall fitting – is disconnected. A camera is run into the duct opening to document the before condition. What we find is photographed and saved to your job record. In Alexandria homes with older foil-flex transitions, this step sometimes reveals a partially crushed duct that is restricting airflow independent of lint load – and that gets noted in writing before we proceed.
- Rotary brush and negative-pressure extraction. A Rotobrush rotary cleaning system drives a spinning brush head through the duct run while a negative-pressure extraction unit – pulling air from the exterior cap end – keeps dislodged debris moving toward the outlet rather than back into the room. For longer runs with multiple elbows, we work in sections, confirming airflow at each bend before moving the brush forward. The brush head size is matched to the duct diameter; most residential dryer vents are 4-inch diameter, but older installations in pre-1980 Alexandria homes occasionally use 3.5-inch or irregular oval configurations.
- Exterior cap cleaning and inspection. The exterior termination cap is inspected and cleared from outside. Louvers or flap-style dampers are tested to confirm they open freely when airflow is applied. If the cap is a wire-mesh type – which is a code violation in Virginia because mesh traps lint and nest material – that is documented and you receive a written note with the cap replacement option and its cost before we touch anything.
- Post-clean camera pass and airflow confirmation. After cleaning, the camera runs the full duct length again. The after photos are compared against the before set and both are delivered to you as part of the standard job record. Airflow at the exterior cap is verified with a meter reading. If it doesn’t meet a clear-duct standard, we don’t call the job done.
- Transition reconnection and dryer test. The transition duct is reconnected – or replaced if it was damaged or the wrong type – and the dryer is run through a short cycle while the technician confirms warm, unobstructed exhaust at the cap. The job record is completed with both camera sets, the airflow reading, and any written notes about cap condition or duct type. You receive that record before the truck leaves.
BeforeAfterVent Cleaning Pricing in Alexandria
Dryer vent cleaning in Alexandria is priced by the specifics of the vent run – not by a promotional rate that expands once the technician is inside your home. The written price you receive before work starts is the price you pay. Below are the ranges we see most often in Alexandria, based on jobs completed since 2013 across neighborhoods from Old Town to Seminary Hill.
| Job Type | Typical Range (Alexandria) | What Drives the Number |
|---|---|---|
| Standard single-story run (up to 15 ft, 1-2 elbows) | $89 – $129 | Most common configuration in Del Ray and Potomac Yard townhomes |
| Extended run (15-25 ft, 3-4 elbows) | $129 – $179 | Typical in split-levels and older colonials with laundry on an interior wall |
| Rooftop-terminated vent | $159 – $219 | Add access time, safety equipment, and exterior cap restoration |
| Nest removal (bird or debris) | $49 – $89 added to base | Applies when nest material requires separate extraction before brush pass |
| Transition duct replacement (foil flex to semi-rigid) | $39 – $65 | Material and labor; priced separately and approved in writing before replacement |
| Exterior cap replacement (standard 4-inch) | $45 – $85 | Includes removal of code-violating mesh cap if present |
A few notes on what affects your price in Alexandria specifically. Homes built before 1985 in neighborhoods like Rosemont, Beverly Hills, and the Braddock Road corridor sometimes have vent runs routed through finished walls with no cleanout access points. In those cases, we photograph the access path and discuss options before quoting any additional scope. Homes in newer construction near Carlyle and Eisenhower Landing tend to have shorter, code-compliant runs with exterior side-wall terminations – those jobs typically land at the lower end of the ranges above.
Every estimate is free, and if you’ve already received a written quote from another company, we’ll put our number next to it in writing at no charge. That’s our Free Second Opinion commitment, and it applies to any written estimate you bring us.
Call (240) 318-7712 to get your written price – every estimate is free, and we don’t start work until you’ve seen the number on paper.
FAQs – Vent Cleaning
How long does dryer vent cleaning take in Alexandria?
Most dryer vent cleaning jobs in Alexandria take between 45 and 90 minutes from setup to job-record delivery. A standard single-story run with two elbows and a side-wall cap – which covers most townhomes in Del Ray, Potomac Yard, and the Braddock Road area – runs about 45 to 60 minutes. Longer runs with rooftop terminations or nest removal add time, and that additional scope is quoted in writing before we start. If you’re booking for a weekday morning slot, plan on about an hour and a half from the time the technician arrives to the time the truck leaves. Call (240) 318-7712 and we can give you a tighter estimate based on your specific setup.
Is dryer vent cleaning actually necessary, or is it just an upsell?
Dryer vent cleaning is necessary, and the evidence for it is straightforward: lint is combustible, dryer exhaust carries moisture that compresses lint into dense plugs, and a blocked vent forces your dryer’s thermal safety to cycle on and off until it fails. The U.S. Fire Administration attributes roughly 2,900 residential fires per year to dryer-related causes, with failure to clean the vent as the leading factor. We’re not in the business of manufacturing urgency – if the camera shows a clean duct, we tell you and we document it. What we do sell is the documentation, so you can see the condition of your vent regardless of what we find. For more context on what the full service covers, see our Dryer Vent Cleaning in Alexandria page.
Can you clean a dryer vent that terminates on the roof?
Yes. Rooftop-terminated dryer vents are more common in Alexandria’s multi-story rowhouses and older colonials than in newer construction, and we’re equipped to handle them. The job requires additional setup time and safety equipment for the exterior access, which is reflected in the written price you receive before we start. Rooftop caps also require a close inspection because they’re more prone to pest intrusion and cap-flap failure than side-wall terminations. The cleaning process is the same – rotary brush and negative-pressure extraction – but the exterior work is done from the roof rather than from grade. Pricing for rooftop jobs typically runs $159 to $219 before any cap or nest work. Call (240) 318-7712 for a written quote specific to your home’s configuration.
What’s the difference between vent cleaning and air duct cleaning?
Dryer vent cleaning addresses the single dedicated exhaust duct that runs from your dryer to the exterior of the home. Air duct cleaning covers the supply and return duct network connected to your HVAC system – a separate system with a separate function. The two services use different equipment, follow different protocols, and serve different purposes. Vent cleaning removes lint and debris from an exhaust path; air duct cleaning removes accumulated particulates from conditioned-air distribution. Some companies offer both in the same visit, and we do as well, but they are never substitutes for each other. If you’ve been quoted a single price that covers “everything,” ask for the scope in writing – specifically, which runs are included and what equipment will be used. Haven Standard Clause 1 means our written price spells out exactly what is and isn’t included before you agree to anything. For the broader service overview, the CleanRun home page covers all service categories.
What the Job Record Looks Like
When the technician leaves your Alexandria home after a vent cleaning, you receive a documented job record – not a receipt, a record. It includes the before-and-after camera photos from inside the duct run, the airflow meter reading taken at the exterior cap after cleaning, the written scope of what was done, any written notes about cap condition or duct material, and the 365-Day Done Right Promise in writing.
The photo record is included on every job as a standard deliverable, not an upgrade. It exists because “your vent is clean” is easy to say and impossible to verify without evidence. CleanRun has documented every job this way since our first vent cleaning in 2013. You can compare your before and after photos yourself, share them with a property manager, or hold onto them for the next service interval. That’s the point.
The 365-Day Done Right Promise means that if something about the work isn’t right in the year following the job, we come back and make it right. That commitment is written on the job record, not described in marketing copy. Haven Standard Clause 5 – the Done Right Promise – is the same whether you’re in Old Town, Seminary Hill, or anywhere else in Alexandria.
