What gas vent repair involves
A vent system is a listed assembly
Vent systems are tested and listed with their own supports, firestops, joints and terminations. One vent maker warns that deleting or modifying any required part can seriously impair the safety of the installation and void its warranty.
That is why we replace missing supports, firestops and shields with the parts listed for the system, not with general hardware. When a previous repair used unlisted parts, we explain what was changed and quote the listed replacements. The goal is a vent that matches the way it was tested.
Shrubs and vines around the vent cap
Shrubs, vines and trees can grow over a wall termination, blocking airflow and holding debris against the cap. Growth can also creep within the clearances the manual sets for the termination.
We look at the planting around the termination and explain what needs cutting back and how much space the manual expects. Trimming plants is a garden task rather than vent work, so we leave that with you or your gardener. Damage the plants have caused to the cap or wall seal is quoted as vent repair.
A bent or crushed termination cap
Termination caps can be bent by ladders, falling branches, strong wind or a knock from outdoor equipment. A deformed cap can change how air enters and gases leave, and it may no longer seal properly to the pipe or wall.
We inspect the cap, its fastening and the pipe behind it. Straightening a listed cap is not a repair we rely on. If it is damaged, we identify the vent maker and system and quote the listed replacement cap, checking the nearest joints while the cap is off.
Termination height above the roof
How high a gas vent must stand is set by the fuel gas code, measured from the roof and from nearby parts of the building. The figures depend on the vent size, the roof slope and what sits close by. For Type B vents, the code also sets a minimum height above the appliance's draft hood or collar.
We check an existing roof termination against those rules and the vent maker's figures. A termination that is too short or too close to a wall can suffer from poor draft or downdrafts. Where an extension is needed, it uses listed sections and is braced as the instructions describe.

Before you book gas vent work
Why does direct-vent pipe have an inner and outer pipe?
A direct-vent system usually runs one pipe inside another. Outside air for the fire comes in through one passage and exhaust leaves through the other, and both stay sealed from the room, which is why each joint and gasket matters.
Is a manual damper allowed in a gas vent?
Not in the vent connector. The fuel gas code prohibits manually operated dampers there, because a closed damper could stop the vent working. Listed automatically operated vent dampers are a different matter and follow their own instructions.
What records do I get after vent work?
A written record of the work that lists the appliance, the vent maker and system, and the route. It also covers the parts replaced, the checks made and anything that stayed concealed or outside the scope.
