How Long a Dryer Vent Run Should Be, and Why Bends Count Against It
Building codes limit dryer duct length and deduct for each bend. The reason is airflow, and airflow is what decides whether lint…

LANHAM
DRYER VENT SERVICES
The complaint in Lanham is usually drying time, and the cause is usually the route rather than the machine. A vent that leaves an upper floor and climbs to a roof termination is longer than the room suggests, turns more often, and drops lint wherever the air slows.

WHY THE LAUNDRY
RUN IS THE PROBLEM.
Lanham is a mix of older single-family houses and newer townhouse groups. The townhouses commonly place the laundry away from an outside wall, which is what makes the vent run long enough to matter.
What that tends to mean
A laundry placed away from an outside wall has to send its exhaust somewhere else, and the somewhere else is always longer. Length and the bends added to reach the outside are what decide how fast the line loads, not the age of the machine.
It also means the line is worth clearing along its whole length: a dryer vent cleaning covers the run from the connection to the termination.
What you can check yourself
Work out roughly how far the exhaust travels from the dryer to daylight, and how many corners it turns. The corners count for more than the feet.
The reason a vertical run behaves differently is worth reading before booking anything.
That is a description of the building stock, not a finding about your property. The scope for any address is set after the system has been seen.
Which service
IS IT THE DRYER,
OR THE DUCT?
Start from what you are noticing rather than from a service name. Each of these points somewhere different.
- The same load now takes two cycles
- Start with the vent line. Drying time is the earliest and most reliable signal, and it moves long before anything else does.
- The laundry room is hot and humid while the dryer runs
- Air that should be leaving the building is not. That is the run, not the appliance.
- You cannot see or reach where it comes out
- Then the termination is the part to establish first — it is the most common restriction and the one nobody checks.

BOTH ENDS.
The line is disconnected at the appliance and cleared along its full length, and the termination is reached and cleared as well. Airflow is checked at the outlet before and after, because that is the number that says whether it worked.

QUESTIONS FROM
LANHAM.
If your question isn't here, send it with an estimate request and we'll answer it directly.
Lanham is one of the places we publish coverage for, as part of Prince George's County. Coverage for a specific address is confirmed on the estimate request rather than assumed from the town name — you get a real yes or no for your address.
The International Residential Code sets a maximum developed length and reduces it for each bend. Which edition applies depends on the jurisdiction, and the appliance manufacturer's instructions govern alongside it.
It restores what accumulation took away, which is usually a noticeable amount. It does not shorten the run, so a long one loads again faster than a short one.
The connection at the appliance is disconnected, cleared and refitted, and the area behind the machine is part of the work. Servicing the dryer itself is the manufacturer's territory.
There is no town price. The figure follows the system in front of us — its length, layout, access and condition — so it is set against your property rather than your postcode. The estimate is free and commits you to nothing.
