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 Fairfax, VA
A dryer vent inspection in Fairfax, VA typically costs between $79 and $149 as a standalone service, takes 45 to 75 minutes, and produces a written report with photographs of every section of your vent run – before any Dryer Vent Cleaning services or repair work begins. If your dryer is taking longer than one cycle to dry a load, or you haven’t had the vent looked at in more than a year, a documented inspection is the right starting point. Call (571) 526-0015 and a live person will answer.
At CleanRun Air Duct Cleaning Fairfax, an inspection is not a sales call with a flashlight for Vent Cleaning. It’s a structured, camera-documented review of the entire vent pathway – from the back of your dryer to the exterior termination cap – with a written scope delivered before anything else happens. That’s how we’ve operated since 2013, and it’s the same approach we take on every one of the 52,000+ homes we’ve served. Tomas Reyes built CleanRun on a simple premise: show the customer what’s actually inside the duct before talking about what needs to happen next.
If you’re already weighing whether cleaning is necessary alongside an inspection, our full Dryer Vent Cleaning in Fairfax page covers what that process involves and what it costs.
When You Need a Dryer Vent Inspection
Some of these are obvious. Others are easy to overlook until something goes wrong. In Fairfax specifically, we see certain patterns repeat – older townhome construction in neighborhoods like Fair Lakes and Burke Centre tends to use longer vent runs with multiple elbows, and those configurations trap lint faster than a straight exterior run in a newer single-family home.
- Your dryer takes two cycles to dry a normal load. This is the single most reliable indicator that airflow is restricted somewhere along the vent run. Restricted airflow forces the dryer to work harder and longer, and lint accumulation at an elbow or transition fitting is usually the cause.
- You feel heat backing up in the laundry room. When exhaust can’t exit cleanly through the termination cap, it finds other paths. If the room around your dryer feels noticeably warmer than the rest of the house during a cycle, that’s exhaust being pushed back into conditioned space.
- The exterior damper doesn’t open when the dryer runs. The exterior vent cap should open freely during operation and close when the dryer stops. A cap that stays partially or fully closed – whether from lint compaction, bird nesting, or a damaged flap – is a blocked system, full stop.
- You haven’t had an inspection in more than 12 months. The U.S. Fire Administration recommends annual dryer vent cleaning and inspection. In Fairfax townhomes and condos where the vent runs vertically through multiple floors before exiting through the roof, that 12-month interval should be treated as a ceiling, not a suggestion.
- You’ve recently moved into the home or had the dryer serviced. A previous occupant’s maintenance history is unknown, and appliance technicians don’t inspect the ductwork as part of a dryer repair visit. An inspection establishes a documented baseline you can reference going forward.
- You’re seeing unusual lint accumulation around the dryer door seal or on nearby surfaces. Lint that’s escaping the drum or blowing back into the room is a sign that exhaust pressure is reversing. This warrants an immediate inspection, not a scheduled one.
Our Dryer Vent Inspection Process
Every inspection follows the same sequence. Nothing is skipped, and nothing is added without your approval. The written scope is produced before work starts – that’s Haven Standard Clause 1, and it applies to inspections the same as it applies to full cleaning jobs.
-
Written Price Confirmation Before We Start
Before the technician touches anything, you receive the written inspection price. This is not an estimate that expands once we’re inside – it’s a fixed scope document. If the inspection reveals conditions that warrant additional work, those findings are photographed, explained in plain language, and priced in a separate written quote. You decide what happens next.
-
Exterior Termination Cap and Wall Penetration Check
The inspection starts at the outside of the house. The technician checks the termination cap for damage, debris blockage, bird nesting material, and whether the damper flap opens and closes freely. In Fairfax’s older housing stock, we regularly find aluminum louvered caps that have partially collapsed or plastic flaps that have warped from heat cycling – both of which significantly restrict exhaust flow even when the ductwork behind them is clean.
-
Camera-Documented Vent Run Inspection
Using a vent inspection camera, the technician photographs the interior of every accessible section of the duct run. The camera shows lint accumulation depth, debris at elbow transitions, foil flex duct that has kinked or partially collapsed, and any moisture or staining that indicates a history of condensation. Foil flex – the accordion-style connector between the dryer and the hard duct – is where problems concentrate in most Fairfax homes, and it’s the section most commonly overlooked in a $79 coupon visit.
-
Airflow Measurement at the Termination Point
Airflow is measured at the exterior termination cap while the dryer runs. This gives a quantified baseline – not an impression, but a number. We use this measurement to confirm whether airflow is within the acceptable range for the dryer’s rated exhaust capacity, and we include it in the written inspection report so you have a documented starting point for future comparisons.
-
Duct Material and Configuration Assessment
The technician documents the duct material (rigid metal, semi-rigid aluminum, or foil flex), total run length, and number of elbows. This matters because the longer the run and the more bends it has, the greater the effective restriction on airflow. A 25-foot run with four 90-degree elbows has roughly the same airflow resistance as a 45-foot straight run – and that calculation affects whether cleaning alone solves the problem or whether a reconfiguration is needed.
-
Written Inspection Report and Photo Record Delivered
At the end of the visit, you receive a written inspection report that includes the before photographs, the airflow measurement, the duct configuration details, and a plain-language summary of what was found. If the inspection reveals conditions that need attention, those are listed with written pricing attached. If the vent is clean and functioning correctly, the report says so – with photographs to confirm it. The photo record is a standard deliverable on every CleanRun visit, not an add-on.
BeforeAfterDryer Vent Inspection Pricing in Fairfax
A dryer vent inspection in Fairfax costs between $79 and $149 as a standalone service. The written price is confirmed before the technician begins work – no exceptions. If additional services are needed based on inspection findings, those are quoted separately in writing. You are not charged for anything that wasn’t agreed to in advance.
| Inspection Scenario | Typical Price Range | What’s Included |
|---|---|---|
| Standard single-story vent run (up to 15 ft, 1-2 elbows) | $79 – $99 | Camera inspection, airflow test, written report, photo record |
| Two-story or townhome vertical run (15-30 ft, 3-4 elbows) | $99 – $129 | Full camera documentation of multi-section run, written report, photo record |
| Complex run – rooftop termination or high-rise condo configuration | $119 – $149 | Extended camera inspection, airflow testing at multiple points, written report, photo record |
| Inspection bundled with full dryer vent cleaning | No additional charge | Inspection is included as part of the cleaning scope – before and after photos document both |
What Affects the Price
- Vent run length and configuration. A straight 8-foot run through a laundry room wall in a newer Fairfax single-family home takes less time to inspect thoroughly than a 28-foot run that travels vertically through a townhome in Penderbrook and exits through a soffit.
- Termination point accessibility. Rooftop caps in condo buildings near Fair Lakes or Old Town Fairfax require additional access time and sometimes a second technician to inspect safely. That affects the written price upfront – it won’t appear as a surprise on the invoice.
- Whether inspection is standalone or bundled. When you schedule a full cleaning alongside the inspection, the inspection is included in the cleaning scope at no additional charge. The before-and-after photo documentation is standard either way.
CleanRun does not do “call for a quote” pricing. The written price for your specific vent configuration is confirmed on the phone or at the door, before any work starts. Call (571) 526-0015 and we’ll walk through your setup and give you the written number. Free second opinion on any written estimate you’ve already received – just bring the competitor’s quote and we’ll put our number next to it in writing.
Why Fairfax Homes Specifically
Fairfax isn’t a uniform housing market. The dryer vent conditions we document inside a 1980s split-level off Braddock Road look nothing like what we find in a 2018 townhome in Kingstowne or a mid-rise condo near the Government Center Metro stop. These differences are not cosmetic.
Older construction in the Mantua and Olde Creek neighborhoods typically has rigid metal ductwork that’s held up well structurally but has years of lint accumulation at elbow joints that were never designed for easy cleaning access. The elbow at the first 90-degree bend after the dryer is often where we find a 2-to-4-inch compacted lint plug – the kind that doesn’t dislodge with a shop vacuum but comes out cleanly with a Rotobrush rotary cleaning system once the inspection has documented its location.
Townhomes built in the late 1990s and early 2000s – common in the Fair Lakes and South Run corridors – frequently have foil flex duct that was installed at the time and has since kinked or partially crushed behind finished walls. A camera inspection is the only way to confirm whether that flex section is still open or has been functioning as a partial restriction for the last several years.
Newer construction near the Mosaic District and Merrifield redevelopment areas sometimes routes dryer vents through exterior walls that face north. In Fairfax winters, that north-facing run creates condensation cycles that leave moisture staining in the ductwork – a finding that shows up clearly in inspection photographs and points toward either an insulation correction or a duct liner solution, neither of which would be apparent without the camera record.
The point of naming these neighborhoods isn’t geography for its own sake. It’s that a documented inspection in Fairfax needs to account for this range of conditions – and a technician who’s been inside these homes since 2013 can recognize a configuration pattern before the camera confirms it.
The Documentation You Receive
Every CleanRun inspection produces a written deliverable. This is not a verbal summary at the door. The inspection report includes:
- Photographs of the duct interior at each documented section, labeled by position in the run
- Airflow measurement at the termination cap, noted in the report
- Duct material and configuration details (run length, elbow count, termination type)
- A plain-language summary of findings – what was observed, where it was found, and what it means in practical terms
- If cleaning or repair is indicated: a written price for each recommended service, itemized, before any agreement to proceed
This documentation is the standard deliverable, included in the inspection price. It exists because a photograph of what was inside your vent run is a different kind of evidence than a technician’s word about what was inside your vent run. We’ve delivered a photo record on every visit since the first job in 2013, and that practice hasn’t changed.
The 365-Day Done Right Promise applies to inspection findings the same as it applies to cleaning and repair work. If a finding is documented in the inspection report and the follow-up work doesn’t resolve it, we make it right – in writing, not at a manager’s discretion.
Credentials and Equipment
CleanRun technicians are background-checked, uniformed, and identified by name before arrival – that’s Haven Standard Clause 3: Verified Crews. Tomas Reyes leads every job under the H.A.V.E.N. Standard, which governs pricing transparency, crew verification, documentation requirements, and the 365-Day Done Right Promise.
For dryer vent inspections and subsequent cleaning work, we use professional-grade equipment – Rotobrush for rotary duct cleaning where lint compaction requires mechanical agitation, and Abatement Technologies extraction systems for negative-pressure collection. These are tools customers can look up independently. We name the equipment because the difference between professional-grade tools and a shop vacuum shows up in the before-and-after photographs – and those photographs go home with you.
CleanRun is independently owned and operated, established in 2013, and has served homeowners across Fairfax with a written price before work starts and a documented photo record when the crew leaves – on every single job, without exception.
FAQs – Dryer Vent Inspection in Fairfax
How much does a dryer vent inspection cost in Fairfax, VA?
A dryer vent inspection in Fairfax costs between $79 and $149, depending on vent run length and configuration – see How Much Does Dryer Vent Cleaning Cost? (2026 Price Guide) - Fairfax, VA for full pricing details. The written price is confirmed before any work begins – that’s not a policy subject to exceptions, it’s how every CleanRun job is structured under Haven Standard Clause 1. A standard single-story run with one or two elbows comes in at the lower end of that range. A two-story townhome run or a rooftop-exit condo configuration falls toward the upper end. When inspection is bundled with a full cleaning, it’s included in the cleaning scope at no additional charge. Call (571) 526-0015 for the written price for your specific setup.
How long does a dryer vent inspection take?
Most dryer vent inspections in Fairfax take between 45 and 75 minutes. A straightforward single-story run with exterior wall termination runs closer to 45 minutes. A multi-floor townhome run or a condo with rooftop termination can take up to 75 minutes to document thoroughly – rushing the camera through a 25-foot run to hit a 30-minute window is how findings get missed. The written report and photo record are produced as part of the visit, not sent separately days later.
Is a dryer vent inspection worth it if my dryer seems to be working fine?
Yes, and the reason is specific: lint accumulation builds gradually, and the point at which a dryer “seems fine” and the point at which the vent is significantly restricted often overlap for a year or more. The dryer compensates for airflow restriction by running longer cycles – you may not notice the change because it happens over months, not days. In Fairfax townhomes with longer vertical vent runs, we regularly find 50% or greater airflow restriction in homes where the occupant hasn’t noticed any performance change. The inspection documents the condition before it becomes a repair or, at the far end, a fire risk. The National Fire Protection Association cites dryer duct blockage as a leading cause of residential dryer fires. An annual inspection is the documented proof that the vent was checked and what condition it was in when it was checked.
Will the inspection tell me if I need cleaning, or do I have to guess?
The inspection report tells you directly what was found and what, if anything, needs to happen next – with photographs attached and written pricing for any recommended work. There’s no guessing involved because the camera shows what’s inside the duct, the airflow measurement shows whether exhaust pressure is within the acceptable range, and the written report summarizes both in plain language. If the vent is clean and functioning correctly, the report says so. If cleaning is needed, you receive a written price for that work before agreeing to anything. For a full breakdown of what the cleaning process involves, see our Dryer Vent Cleaning in Fairfax page.
Can you inspect a dryer vent the same day I call?
In most cases, yes. CleanRun has same-day availability across Fairfax for dryer vent inspections, and all calls are answered by a live person. Call (571) 526-0015 and we’ll confirm the earliest opening for your neighborhood. If same-day isn’t available, next-day scheduling is standard. We don’t hold slots behind a scheduling form – a real person answers and books you directly.
What’s the difference between a dryer vent inspection and dryer vent cleaning?
An inspection is a camera-documented assessment of the vent run’s current condition – it produces a written report and photographs but does not clean the duct. Cleaning uses rotary brush and negative-pressure extraction equipment to remove lint and debris from the duct walls and deliver a clean, open vent run. Cleaning produces its own before-and-after photo record. The two services are related but distinct: inspection tells you what’s there, cleaning removes it. When you schedule a Dryer Vent Cleaning in Fairfax with CleanRun, inspection is included in the scope – you don’t pay for it separately.
