The short answer
Why Repointing Matters
Mortar is softer than brick, so it absorbs movement and weather. Over time, water seeps into cracked or missing mortar, especially in a humid subtropical climate with spring hail and thunderstorms. If left, moisture can reach the brick and cause spalling or interior dampness.
Repointing restores the mortar's protective role. It also improves the wall's appearance. The work is precise, and the new mortar must be compatible with the old brick to avoid trapping moisture. A skilled mason or a water damage pro can assess whether your brick needs this treatment.
Steps in the Repointing Process
The first step is to remove the old mortar. A pro uses a grinder or a chisel to cut out mortar to a depth of about twice the joint's width, or until sound mortar is reached. This is done carefully to avoid damaging the brick edges.
After the joints are cleaned of dust and debris, the new mortar is mixed. The mix should match the original in color, texture, and strength. Then it is pressed into the joints with a trowel or a mortar bag, and the excess is struck off. The finish is shaped to the joint style, such as flush or recessed.
The pros work in small sections so the mortar does not dry too fast. They also protect surrounding areas from mortar splatter. The final step is to let the mortar cure slowly, keeping it damp for a day or two to prevent cracking.

Tools and Materials
Repointing requires basic tools like a tuck pointer, a jointing tool, and a brush for cleaning. A grinder with a diamond blade is used to cut out old mortar. Safety gear, including goggles and a dust mask, is essential because brick dust is harmful to breathe.
The mortar mix is usually a blend of Portland cement, lime, and sand. Lime keeps the mortar flexible and breathable. The exact proportions depend on the brick's hardness and the original mortar. A pro will test a small area first to find the right mix.
For large areas, a mortar bag or a pump may be used to speed up the work. But for most homes, hand tools are sufficient. The key is to match the color and texture, which often requires blending different sands.
When to Call the Pros
If you notice crumbling mortar, damp spots on interior walls, or water stains near brick, it is time to consider repointing. Small patches can be a DIY project, but large areas or high walls are safer for the pros. They have the equipment to work at height and the experience to match mortar.
Water damage pros often see repointing needs after leaks or floods. If water has penetrated the brick, they can also dry out the wall and check for hidden damage. If you live in Euless, keep an eye on brick after heavy storms.
The pros can also handle related issues like efflorescence, which is a white salt deposit on brick. They will know if the problem is just cosmetic or a sign of ongoing moisture. Addressing it early can prevent bigger repairs.
Cost and Duration
Repointing costs vary widely. It often depends on the wall's height, the condition of the mortar, and the type of brick. A typical range is $5 to $15 per square foot, but that can change with accessibility and local labor rates.
A small wall can be done in a day, while a full house may take a week or more. The pros will work in sections to keep the wall usable. Weather matters: mortar should not be applied in freezing or very hot conditions.
Budget for materials and labor. Some homeowners choose to repoint only the worst areas, but a complete job gives a more uniform look. Ask the pros for a breakdown of costs before work begins.

Can I repoint brick myself?
You can, for small areas. But it is labor-intensive and easy to get wrong. Matching mortar color and strength takes practice. If the wall is high or the mortar is extensive, hiring the pros is safer and gives a neater finish.
How long does repointing last?
Good repointing can last 20 to 50 years, depending on weather and mortar quality. In harsh climates, it may need more frequent attention. Regular inspection helps catch problems early, so you can repair small areas before they spread.
Does repointing stop water leaks?
Repointing helps keep water out, but it is not a complete waterproofing solution. If water enters through other paths, like cracked brick or faulty flashing, those need fixing too. A water damage pro can identify all entry points and suggest the right repairs.
