On 2018 08 05 by mod replacing the chimney cleanout door replacing the chimney cleanout door assuming it is on the inside of the building would not explain a water leak problem through the chimney into the building unless in the course of replacing the door someone pounded on masonry and cracked or broke the chimney walls.
Chimney cleanout door leaking water.
Do not use sealant to caulk shut the cleanout door of a chimney that is in active use as you ll need to be able to open the door later to inspect or clean the chimney base.
Is your roof leaking.
It s always below the chimney but it s usually in your utility room in most homes you ll find a pipe coming across from your furnace hot water tank or boiler that ll come across and there s a hatch at the base.
Gas appliances output a lot of water vapor and if it s not venting properly it will condens.
Use a plumber s putty or even play doh to build a dam on the floor around the cleanout door area.
What this is the metal door that is usually in your furnace room.
Seal a leaky chimney cleanout door where the flues are in use.
Could experiment if not afraid of a bit more water one person with hose one watching ashpit try running a hose for just long enough to pool a bit of water against the foundation of the chimney also along the sides of the chimney on the roof above the chimney but not against it then pouring vertically down on top of the rain cap if not open mesh which obviously would let water in might be able to replicate which of those areas the water is coming from.
It surrounds the clay flues but doesn t encase them.
It has an angled top to shed water and it overhangs the brick to keep drips off the chimney sides.
Move the shelves out of the way and make the dam around a fairly large area.
Gap allows the clay flues to expand and contract from repeated heating and cooling without cracking or cracking the crown.
Before sealing a chimney cleanout door shut be sure that the door serves only the chimney or flue that is being abandoned.
That will narrow down the area where the water is coming in.
This tells you if you should waterproof the chimney.
