Chimney Pot Installation Tips
Installing chimney pots is quite easy and most installations require a few hours.
The tools you’ll typically need are simple:
- a ladder, a trowel, and mortar.
- Wire mesh and silicon caulk for a top screen are optional.
- For areas with severe weather, you may
wish to add a matching terra cotta rainguard.
1. Attach Wire Mesh (Optional)
Prior to bringing the chimney pot to the roof, you may wish to cut wire mesh to the size of the chimney pot’s top opening and secure with silicone caulk. This will prevent leaves and animals from entering the flue
2. Remove Excess Flue Tile
Remove any flue tile that extends above the top of the chimney using a circular saw and masonry blade. This will ensure that, after installation, water will not be come trapped in the space between the tile and the chimney pot, where it could freeze and cause damage
3. Place the Chimney Pot in Mortar
Once the flue tile is level with the chimney top, lay three inches of mortar around the flue. Place the chimney pot into the mortar and push it down to ensure a good hold.
4. Taper the Mortar
Using a trowel, taper the mortar up to the chimney pot. This will allow rainwater to run down away from the chimney pot rather than become trapped between the chimney pot and mortar, where it could freeze and expand.
Once installed, the mortar holding the chimney pot should be inspected for cracks at least every 10 years, but preferably whenever the chimney is swept. Chimney pots themselves rarely break.
