Dryer Vent Rerouting
A shorter, legal path for runs the original builder made too long.
Learn moreWhen a duct run genuinely exceeds the length a dryer can push through — common in townhomes and homes with island laundry rooms — and no shorter route exists, the code-recognized fix is a dryer exhaust duct power ventilator: an inline booster fan listed for dryer duty. We install the unit with service access, wire it to switch on automatically when the dryer runs via its pressure sensing, and verify the full run under load. We are equally ready to tell you a booster is the wrong answer; if a reroute solves it with less hardware to maintain, that's the recommendation you'll get, with the math to back it.
A dryer exhaust duct power ventilator — DEDPV, commonly called a booster fan — is an inline fan listed specifically for dryer exhaust, installed when a duct run is genuinely longer than the dryer can push and no shorter route exists. It senses pressure when the dryer starts, switches on automatically, and carries the airflow the rest of the way to the termination. The 'listed for dryer duty' part is not pedantry: generic duct fans collect lint on unprotected motors, which is how a fix becomes a hazard. A correct DEDPV install includes service access, verified automatic operation, and a full-run airflow test under load.
At Prime Dryer Vent Experts, a booster fan (dedpv) installation is never guesswork. We scope every job from a camera vent inspection first — mapped route, measured developed length against IRC M1502, and airflow readings — so the work is matched to what your duct actually needs, with the report to prove it. The documented inspection is the record the booster fan (dedpv) installation is built on.
Camera vent inspectionA booster fan (dedpv) installation isn't a matter of opinion — it's held to published national standards. Prime Dryer Vent builds every job to the named codes below and documents it, so the work is provably right for an inspector, an insurer, or a future buyer. These are the universal standards; your city's permit and inspection requirements are confirmed with the local authority before we pull the job.
Where a run exceeds the standard length allowance, the code recognizes a listed dryer exhaust duct power ventilator installed in accordance with its listing and the manufacturer's instructions.
Codes cited are the established national standards (IRC, UL) that govern this service. The adopted code edition, permit, and inspection requirements vary by city —Prime Dryer Vent verifies them with your local authority having jurisdiction on every job.
We measure the actual developed length and confirm a booster is the right answer — and tell you plainly if a reroute is smarter.
The DEDPV is positioned per its listing along the run and mounted with clearance and access for future cleaning.
The unit is wired and its pressure-activated start is configured so it runs exactly when the dryer does.
We run the dryer and verify airflow along the full run and at the termination, recording the numbers on your report.
We've worked on 0+ DFW homes over 15+ years. Every job — small vent cleaning or full rebuild — runs the same way: licensed & insured technicians, written quotes, photo reports, warranty in writing.
We recommend a booster only after the developed-length math says a reroute can't win
Only DEDPV-listed units built for lint-laden air — never generic inline fans
Mounted with real service access, because a booster is a maintenance item, not a burial item
Automatic pressure-sensing operation is demonstrated to you before we leave
Family-owned, licensed & insured, IRC M1502–compliant. We're the team you call when you want it done right the first time — no rotating subcontractors, no upsell pressure, no surprises. Same techs, same trucks, same standard.

For most households, once a year is the right rhythm. Push it earlier if the dryer runs daily, the run is long or has several elbows, you have pets, or the machine is gas-fired. The honest answer is measured, not guessed: if airflow at your termination is strong and drying times are normal, you can wait; if either slips, don't. Our inspections give you that measurement so the schedule fits your house instead of a generic calendar.
No. Dryer vents are the entire company — cleaning, inspection, repair, rerouting, rebuilds, and installs of the dryer exhaust system only. That's a deliberate choice, not a limitation: a crew that works on one system all day gets very good at it, and a visit from us never turns into a pitch for six other services. If your problem is outside the dryer vent, we'll say so plainly and you'll owe us nothing for the opinion.
In the Dallas–Fort Worth metro we can typically respond within about two hours for urgent calls — a fully blocked vent, a burning smell, a gas dryer you're worried about. Routine cleanings and inspections are usually scheduled within a couple of days. Outside DFW, in the Austin, San Antonio, and Houston metros, response depends on route density that week; we'll give you a real window when you call rather than a number we can't keep.
Cleanings start at $99, inspections and diagnostics at $89, and repairs are quoted flat after we've scoped the duct. The published prices are true starting points; what moves them is physical: duct length, elbow count, second-story or roof access, and how compacted the lint is. You approve the exact number before any work starts, and the price we quote is the price you pay. No trip-fee surprises, no truck-side renegotiation.
We measure airflow at your outside hood first, so there's a baseline. Then the full run gets cleaned — rotary brush through the duct while a HEPA vacuum holds it under negative pressure, plus the transition hose behind the machine and the termination hood outside. We re-measure airflow, reset your dryer with proper clearance, and hand you a report with the before/after numbers and photos. Most homes take about an hour, and we leave the laundry room cleaner than we found it.
