What gas vent repair involves

A termination cap loose on the wall

A wall termination is fastened to the outside wall and sealed to the wall covering as the vent instructions describe. Over time, fasteners can loosen and sealant can fail, letting the cap move and water reach the wall.

We check the fastening and seal and look at the wall covering around the termination. Loose fastenings are secured with the fasteners the instructions call for, and failed seals are renewed with the specified sealant. If the wall covering behind has been damaged by water, that repair is listed for the right trade.

Heat marks on framing near the pipe

Vents need specified air space to framing and other combustible materials. Manuals warn that insulation and other materials must be kept away from the vent pipe, because failing to keep that air space can lead to overheating and fire.

Darkened wood, scorched paper facing or heat-softened materials near a vent are serious findings. We explain what we see and why the fireplace should stay off. The repair restores the listed clearances, which may involve moving framing or material. That work is quoted and approved before the appliance is used again.

Negative pressure inside the house

A natural-draft fireplace depends on the pressure inside the house. Range hoods, bath and kitchen fans, dryers and other fuel-burning equipment can all pull on the house. So can poorly placed air returns, an unbalanced air handler and leaks in the upper floors, according to one appliance manual.

If your fireplace behaves differently when other equipment runs, tell us. We can test the draft under those conditions and explain the result. Fixes on the house side, such as makeup air or sealing leaks, belong to other trades. We note them clearly so the vent is not blamed for a building problem.

Cleaning up after vent work

Vent work can involve attic dust, insulation, old pipe, sealant and packaging. We protect floors and furniture along the route through the house and keep insulation where it belongs.

Removed pipe and caps leave with us, or stay with you if you ask. Debris from the attic, the roof and the room is cleaned up and hauled away. If an access opening is left for a finish trade to close, we make it tidy and safe and tell you what remains to be done.

Gas vent work, questions and answers in Broadview Park

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.

Can a new window or door near the termination cause a problem?

It can. Terminations need clearances from openable windows and doors, and a new opening can fall inside them. We measure the relationship against the manual and explain whether the termination or the opening needs to change.

Can you check the vent without taking the fireplace apart?

Partly. Exposed pipe, the termination and the roof or wall exit can often be checked without opening the appliance. The collar connection and concealed joints may need panels or access opened, which we explain before doing it.
