Brick is a sturdy, long-lasting building material—but mortar isn’t. Regardless of where you live, your mortar will start to show signs of wear after about 30 years of use and require repointing. The job itself is fairly simple, although the work does start to stack up. Plus, any minor mistakes could lead to larger repairs down the chute.
In this guide, we outline the steps brick by brick to give you a sweeping look at how to repoint brickwork and whether or not it’s a job for you or if you should hire a pro to help.
Clean the Brick
Your brick needs to be clean for the mortar to set. Wipe any dirt or debris off the dirt with a cloth or broom.
If pressure washing is part of your standard brick maintenance (and you feel confident tackling it safely), you can do this prior to repointing. But, don’t do it the day or two before, as you want to make sure the brick isn’t soaking wet before you start.
Remove Old Mortar

Use your chisel to remove about ½ inch depth of chipped or broken mortar from both the vertical and horizontal joints, making sure not to damage the bricks themselves. Brush away any dust and debris with your wire brush as you go.
Remember, mortar is what keeps brick solidly in place. So, work in small sections (about 3 by 5 feet) to maintain the integrity of your structure.
Wet Your Brick
Did we mention that the brick needs to be cleaned? Wipe away all dust and grime from step two. Then, use a wet washcloth to dampen the entire area to help slow the mortar setting process to a manageable speed, but don’t get it too wet. Too wet a surface could prevent adhesion.
Mix The Mortar
Pour some of the mortar dry mix into your bucket, and slowly mix in water. Don’t mix all your mortar at once, as it hardens quicker than you think, and you can always mix more as you go.
Stir with your trowel until it reaches the desired consistency—it should be like peanut butter or thick frosting. When you pull the trowel out of the mortar, it should hold its peak (like the top of a cupcake).
Apply The Mortar

Using your small finishing trowel, scoop a smaller amount of the mortar off the large trowel and press it into your now-clean joints until it’s nearly full and flush with the brick, but not all the way. Start with your head joints (vertical joints) and then move to the bed (horizontal) joints. Wipe away any excess mortar immediately with your wet cloth.
Use smooth, consistent pressure to make sure there aren’t any bubbles in the mortar. Any pockets of air can weaken your wall’s structure—leaving you at risk from one big huff and puff that can blow your house in.
Let it Rest
Set a timer for about 45 minutes to allow your mortar to rest. You want it to be dry enough that no mortar gets on your finger when you touch it, but still wet enough that you can still mold the shape of it.
Clean Up The Joints
Now’s the time to shape your joints and clean up any excess mortar on the brick. Use your jointing tool to mold the mortar to match the finish of the rest of your brick. Brush any excess mortar away gently with your wire brush, being extra careful around your new joints.
Mist it Every Day

Mistakes to Avoid
Although it may not seem difficult when you’re reading the steps in your head, there are a few things to be wary of that could impact the stability and longevity of your final product.
Not removing enough of the mortar. If you leave any old mortar in the joint, your new mortar won’t adhere properly—which can lead to more cracks and issues down the road.
Working in too large sections. Opt for smaller, more manageable sections to prevent the mortar from drying before you can smooth or wipe it away.
Not paying attention to the forecast. Mortar takes a few days to dry, and the weather needs to stay stable during that timeframe. Most mortar requires a temperature between 40 and 100 degrees Fahrenheit, but may be more or less depending on your brand.
Using the wrong mortar. While you’ll probably notice areas where you repoint your brick, straying too far away from your mortar color can be a pretty unappealing surprise.
DIY vs. Hiring a Pro
Repointing brickwork isn’t necessarily a hard job in terms of the step-by-step work, but it does take a long time and comes with a few risks. And if the area you need to tackle requires an extra-tall ladder or even scaffolding, your best bet is to hire a mason anyway. They’ll have the tools and know-how to do the job efficiently and safely.
You’ll pay anywhere from $400 to $2,500 on average, although your specific cost for repointing brick depends on the size of the area, how intricate your design is, and whether or not scaffolding is needed. And if it’s a chimney, your costs can climb pretty quick.
