Brick repointing replaces deteriorated mortar between bricks while leaving sound masonry in place. A careful job starts with inspecting the wall and identifying why the joints failed. Then the crew removes loose mortar, prepares the joints, and packs in compatible new material. The work can create dust and involve noise, so knowing the steps helps you plan around the repair and understand what good workmanship should look like.
Inspecting the Wall
Before work begins, the contractor checks the mortar joints and the condition of the bricks. They look for crumbling, gaps, moisture entry, and signs that earlier repairs used a material that does not suit the wall. They may also inspect nearby flashing, gutters, or drainage, since water problems can contribute to mortar damage.
The inspection helps define which areas need repointing and whether any bricks need separate attention. Ask the contractor to explain the repair limits and how they will protect doors, windows, plants, and walkways. If the wall has movement, extensive cracking, or persistent moisture, those issues may need assessment before repointing can solve the problem.
Removing Damaged Mortar
The crew removes deteriorated mortar from the joints, usually with hand tools or power tools fitted with controls suited to the masonry. They work carefully to avoid widening the joints or chipping brick edges. The required depth depends on the condition of the joint; simply coating the surface with new mortar will not create a durable repair.
Expect some noise and dust during removal. A responsible crew uses dust control, keeps the work area organized, and shields nearby surfaces as appropriate. After removal, they clear loose debris from the joints. You can help by moving nearby items and keeping people and pets away from the work zone.
Matching Mortar and Brick
Replacement mortar should suit the existing brickwork, not just look similar when wet. Contractors consider the original mortar’s color, texture, joint profile, and strength, along with the age and type of brick. A mortar that is too hard can put stress on softer bricks, while a poor color or finish can make repairs stand out.
Ask to review a small sample or test area before the crew repoints a prominent section. Mortar often changes in appearance as it cures, so judge the match after it has dried. The contractor should also agree on the joint shape and finish, since these details affect both appearance and how water sheds from the wall.
Applying and Curing Mortar
Once the joints are prepared, the crew packs fresh mortar into them in controlled layers and finishes the surface to match the agreed profile. They work in manageable sections so the mortar can be finished at the right stage. Careful application fills the joint rather than leaving voids that could allow water to enter.
Fresh mortar needs suitable conditions as it cures. The crew may dampen the masonry or protect the work from strong sun, wind, rain, or freezing conditions, depending on the materials and weather. They should explain any temporary covers and when they can be removed. Avoid touching or washing the repaired joints until the contractor says the work is ready.
A sound repointing job depends on careful removal, a compatible mortar choice, neat application, and proper curing—not just a fresh surface appearance. Before work starts, confirm the repair area, finish, and protection plan with your contractor.
