Tuckpointing: The “Fine Art” of Mortar Repair

You may not know it, but the use of brickwork and masonry dates back as far as 7,000 BC. For centuries, bricks and mortar have provided a dependable means of construction for homes and buildings that are both durable and beautiful. While the actual bricks used for exterior and interior walls, chimneys, and fireplaces tend to hold up very well over time, the mortar used between the joints will unfortunately deteriorate and have to be replaced. In the construction industry, this process is called tuckpointing. 

In tuckpointing, the first step is to remove the old mortar where separation and cracking have occurred using a grinder or a chisel. Next is the preparation of the new mortar – paying special attention to color-match the existing mortar. The new mortar is then applied using a grout bag and trowel to match the existing joints closely. Finally, the finished surface must be cleaned and resealed. If done correctly, a new tuckpointing job will leave the structure renewed, strengthened, and ready for many more years of use.

The more adventurous homeowners will often ask if tuckpointing is a DIY project.  Frankly, attempting quality masonry work without a lot of experience can be very difficult, often producing disastrous results. And be forewarned – tuckpointing is a fairly dirty affair. Grinding the joints creates one heck of a dust storm with mortar chunks flying everywhere and covering the ground. Matching mortar color is especially challenging as mortar tends to dry to a lighter color than when it is wet. It takes a skilled hand to get this part right. However, if you are determined to give it a go, the best way to start is with a small test batch of mortar applied in an inconspicuous place. Allow the test mortar to dry thoroughly and see how it looks. Then make color adjustments as necessary. Before you start grinding away, be sure to cover the ground with a large tarp or drop cloth. Other tools needed for a proper tuckpointing job include a grinder, masonry chisel, pressure washer, mortar, mortar color, grout bag, trowels, and most importantly – protective eyewear and heavy-duty dust masks. You’ll also need a steady hand and a lot of patience. 

The hard truth is that when it comes to deteriorating mortar and repairing cracks or separation in a foundation, there is no alternative solution to tuckpointing. While there are other options and procedures necessary to stop settling in a foundation, tuckpointing is the only professional way to repair cracks or separation after the foundation has stabilized. While each job is unique and specific, on average, you can expect to spend between $800 and $1,000 on a quality tuckpointing job.
