Vents break in predictable ways
Dryer vents take abuse. The flexible hose behind the dryer gets crushed when the machine is pushed back against the wall. Sections in the attic get stepped on or pinched by stored boxes. Joints pull apart over years of vibration. Foil and plastic flex hose sags, tears, and traps lint in every fold. Each of these narrows the airway, and a narrow airway means trapped heat and lint — the fire combination.
What we repair
We replace crushed transition hoses with proper rigid or semi-rigid metal duct. We reconnect pulled-apart joints and seal them with metal tape — never screws inside the duct, which snag lint. We replace plastic and foil accordion duct with smooth rigid metal, the material fire safety guidance calls for. We re-support sagging runs so they hold a straight, short path. And we fix vents that were cut too long behind the dryer, which is the most common cause of crushing.
Repair or replace the run?
Small damage gets repaired: a crushed section, a bad joint, a torn hose. But when the whole run is the wrong material, or it zigzags through the house with too many bends, patching is throwing money away — we will tell you when a full reroute is the honest answer. Our rerouting service handles that. Either way, you get the straight call during the free estimate.
The wrong materials, explained
If your vent uses white plastic or shiny foil accordion hose inside the wall, it needs to go. Both are flammable, both trap lint in their ridges, and both crush flat behind the dryer. Building safety guidance calls for rigid metal duct with smooth interior walls. It costs a little more to install and it is worth every penny — it is the single biggest safety upgrade a vent can get.

Our Process: How It Works
Step 1 — Free estimate with diagnosis. We inspect the full vent line, find every damaged section, and show you photos of what is wrong.
Step 2 — Written quote, your approval. You get itemized pricing for the repair. Nothing happens until you approve it.
Step 3 — The repair. We replace damaged sections with rigid metal duct, reconnect and seal joints with metal tape, and re-support sagging runs.
Step 4 — Test and clean. We run an airflow test to prove the fix worked, and we clean the repaired line so you start fresh.
Materials we use — and why
We repair and replace with rigid metal duct: smooth interior walls that do not trap lint, sturdy enough to hold its shape, and non-flammable. Joints get sealed with metal foil tape — never screws driven into the duct, which catch lint and start new clogs. Transition hoses behind the dryer get semi-rigid metal, which resists crushing far better than foil accordion hose while still flexing enough for the connection. Hangers and straps support long runs so they do not sag between attachment points. These are not premium upgrades; they are simply the correct materials, and they are what safety guidance calls for.
Repairs we will not sell you
Honesty cuts both ways. We will not patch a vent that needs replacing — if the whole run is plastic accordion duct with five bad joints, a patch is your money wasted. We will not "seal" a disconnected vent that was never routed to the outside; it needs a proper termination. We will not install a booster fan to compensate for a vent that should be rerouted shorter. And we will not clean a vent we believe is unsafe to use — if we find something dangerous, we tell you plainly and quote the real fix. Our reputation is worth more than any single job.
How damage happens — and how to prevent it
Most vent damage is accidental. The dryer gets pushed back and crushes the hose. Boxes in the attic get stacked on the duct. A handyman drives a screw through the duct hanging a shelf. The original installer used the flimsiest flex hose and it finally gave out. Prevention is simple: leave space behind the dryer, keep storage off attic ductwork, and when anyone works near the vent line, mention it is there. A vent left alone in rigid metal duct can serve for decades without a single repair.
Emergency repairs: when it cannot wait
Some vent problems are urgent. A burning smell from the dryer means stop using it and call us — we prioritize these visits. A vent that has come completely apart in the attic is pumping gallons of moisture into your insulation with every load. A crushed transition hose behind the dryer is strangling airflow right now. When you call with an urgent vent problem, tell us what is happening and we will get you scheduled fast. Do not run the dryer until we have looked at it — a day of damp clothes beats a fire.
The attic: where vents go to suffer
Attic vent runs take the worst abuse in the house. Boxes get stacked on them. Workers step on them. Summer heat bakes the duct and dries out old tape. Over years, supported runs sag between hangers, creating low spots where lint collects and moisture condenses. During repairs we do not just fix the broken section — we re-support the whole attic run so it holds a straight, proper line. A vent that runs straight and supported stays trouble-free; one that sags and dips is a recurring problem.
After the repair: what changes
Homeowners are often surprised by how different the dryer feels after a proper repair. One cycle instead of two. The top of the dryer warm, not scorching. The laundry room dry instead of damp. Less lint on clothes. These are not small quality-of-life improvements — they are what a correctly working vent feels like, and many people have never experienced it because their vent was compromised from the day they moved in.
