How we assess and repair gas vents
What Type B vent is for
Type B gas vent is a double-wall pipe used with natural-draft gas appliances. The fuel gas code requires it to be listed to UL 441, and one vent maker lists it for draft-hood appliances and other appliances listed for Type B vent. It relies on warm gases rising, with combustion air taken from the room.
If your fireplace uses Type B vent, the route must rise to a roof termination with a listed cap. We check that the appliance manual calls for Type B vent and that the installed parts belong to one listed Type B system.
Water collecting at a wall termination
Some manuals ask for a horizontal termination cap to slant slightly downward so that moisture inside it can drain out. A cap set level or tilted back toward the house can hold water, which may run back along the pipe or into the wall.
We check the angle of the termination against the manual and look for staining on the wall and pipe below it. Where the cap or the last section was set wrongly, it is reset to the instructions. Any water damage to the wall behind is listed for the appropriate trade.
Leaks at a roof penetration
A vertical gas vent passes through the roof with flashing and a storm collar. One vent maker calls for a ring of nonhardening high-temperature sealant, such as silicone, around the pipe at the top of the storm collar to keep the roof watertight.
A ceiling stain near a vertical vent can mean the collar, sealant or flashing has failed. We check them where the roof can be reached safely and explain what we find. Vent-side repairs are quoted by us. If the roof covering around the flashing needs work, a roofer handles it.
Gas and wood caps on the same roof
A staggered pair of terminations, one gas and one wood-burning, must have the wood-burning top standing above the gas cap under one manual's rules. The arrangement keeps smoke from the wood appliance away from the gas termination.
We check the relationship between the two terminations and explain what the manual requires. If the gas cap sits higher or too close, relocating or extending the gas vent within its tables may be the answer. Work on the wood-burning chimney itself belongs to our chimney services and is quoted separately.

Before you book gas vent work
What does a B-vent installation from you include?
Listed Type B pipe and fittings, with the firestop spacers, attic insulation shield, supports, roof flashing, storm collar and listed cap the vent maker specifies. The route is sized and set to the appliance manual and the fuel gas code.
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.
What happens to the old vent parts you remove?
We take them away with the other debris, which is cleaned up and hauled away before we leave. If you would like to see or keep a damaged section, say so and we will set it aside for you.
