Having a chimney is a great feature for any home and greatly increases your home’s value. However, maintaining a chimney can be quite time consuming and — if it isn’t properly maintained — can end up being costly to repair.
One of the most common issues homeowners face with their brick chimneys is crumbling mortar. Mortar is the cement-like substance used to hold the bricks in place. Without it, the chimney will collapse under the slightest breeze. To repair crumbling mortar, you’re going to need a few tools and materials first:
- Gloves and safety goggles
- Hammer and cold chisel
- Mortar mix
- Mortar bag
- Wire brush
All of these items can be purchased at your local home improvement and/or hardware store for reasonable prices. Purchasing these items also means you have them if you need to make repairs in the future.
How to Repair the Mortar
- Use the hammer and cold chisel to chip away at cracked mortar. Make sure the cracks are free of old mortar debris by using the wire brush.
- Next, mix your mortar using the mortar mix and adding water according to packaging instructions. Be sure not to make too much at one time or else the mixture could end up drying up before you use it.
- After making the mortar, place it in the mortar bag and use the nozzle end to squeeze the mixture into the newly cleaned out joints.
- As you work (NOT after you’ve finished), use the trowel to scrape away excess mortar from the joints to create a more smooth appearance.
- After repairing the damaged area, let the mortar sit for at least an hour, then go back and wipe away the mortar from and brick surfaces with a damp sponge.
