Gas vent pipes, joints and terminations
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.
Spillage at the draft hood
On a natural-draft appliance, the draft hood relief opening should draw air in while the unit runs. If combustion products spill out of that opening instead, the vent is not drawing properly. One manual warns that negative pressure can cause spillage of combustion fumes and soot.
We carry out a draft check at the draft hood after the unit has warmed up, following the vent maker's method. If it shows spillage, the fireplace stays off while we trace the cause, which may sit in the vent, the termination, the house pressure or the appliance.
Vent parts disturbed during renovation
Renovations can disturb a vent without anyone noticing. A joint can be knocked apart behind a new ceiling, supports removed, insulation blown against the pipe or a termination hidden behind new siding.
If the fireplace started behaving differently after renovation work, tell us what was done and where. We check the accessible route with those areas in mind and explain which sections are concealed. Access to check a concealed section is proposed as its own item, so you can decide whether it is needed.
Workmanship warranty on the vent work
Our workmanship warranty covers the vent work we carry out, such as fitting sections, locking joints, fitting supports and sealing penetrations. Vent parts carry their makers' own warranty terms.
If a problem appears with the vent work we did, let us know and we will return to look at it. If the new problem has another cause, such as later building work near the termination, we explain the difference before quoting anything. The estimate states which warranty covers what, so there is no confusion later.
What we check along a gas vent

Direct-vent and B-vent questions we hear
Can a new air conditioning unit affect the vent termination?
It can. Terminations need distance from mechanical air intakes so combustion products are not drawn into the house, and equipment placed close to a cap can crowd it. We measure the arrangement against the manual and explain which item would need to move.
Is a decorative shroud allowed over the termination?
Only a listed decorative cap or shroud made for your vent system. The manuals warn that decorative covers can change the clearances a cap needs, so we check the listing and the clearances before fitting one.
Can Type B vent be used on any gas appliance?
No. The vent maker lists Type B vent for appliances with draft hoods and others listed for Type B vent. It is not for appliances that can be converted to burn solid or liquid fuels. The appliance manual confirms which vent applies.
