Tuckpointing helps restore the mortar joints between bricks, improving both the appearance and durability of your home. Over time, mortar can crack, crumble, or erode, allowing water to penetrate and cause more serious damage. Catching failing mortar early can help keep water out and prevent more extensive repairs later.
While some homeowners can handle small tuckpointing projects, the process depends on careful prep and consistent technique to hold up over time. We break down how tuckpointing works, when it’s needed, and which repairs you can handle yourself versus when to call a pro. Our guide also includes insights from This Old House mason Mark McCullough.
What Is Tuckpointing?
Tuckpointing is the process of removing damaged or deteriorating mortar from brick or stone joints and replacing it with fresh mortar. This helps restore both the appearance and structural integrity of a wall.
Over time, mortar can crack, crumble, or erode, allowing water to penetrate behind the brick. Left unaddressed, this moisture can lead to more extensive damage and weaken the overall structure.
Signs Your Home Needs Tuckpointing
The condition of your mortar joints can reveal whether tuckpointing is needed. In many cases, early signs of deterioration are easy to spot and can help prevent more extensive damage if addressed promptly.
Crumbling Mortar
Mortar that is crumbling, falling out, or appears powdery is one of the clearest signs of deterioration. As the joints weaken, they lose their ability to hold bricks or stones securely in place.
Visible Cracks in Joints
Small cracks in mortar joints can allow water to penetrate the structure. Cracks wider than a hairline are a sign that the mortar is failing and may need to be replaced.
Water Damage on Interior Walls
Damage is not always visible from the outside. Interior signs such as damp spots, discoloration, or a white, powdery residue known as efflorescence can indicate that water is entering through compromised mortar joints.
Tuckpointing Tools and Materials
Having the right tools and materials is essential for a successful tuckpointing project, especially to ensure proper adhesion and long-term durability.
According to This Old House Magazine, using the correct type of mortar is especially important, as the wrong mix can damage older brick or fail prematurely.
Below are the basic tools and materials you’ll need:
- Joint raker or grinder: Used to remove old mortar from between bricks or stones
- Masonry brush: Helps clean joints and apply treatments to the surface
- Mortar Mix: The primary material used to refill joints
- Pointing hawk: Holds mortar while you work
- Safety gear: Includes gloves, eye protection, and a dust mask
- Tuckpointing trowel: Used to apply and shape mortar in tight spaces
Most hardware or home goods stores should have everything you need. If you need help finding anything, ask an associate.
The Tuckpointing Process: Step-by-Step
Tuckpointing requires careful preparation and consistency to ensure the new mortar bonds properly and performs over time.
Begin by cleaning the brick and mortar joints, removing dirt, debris, and any loose material. Protect surrounding areas, such as landscaping, from falling mortar or dust.
Use a joint raker or grinder to carefully remove old, damaged mortar from the joints. You need to remove enough of the old mortar to allow the new material to bond. This Old House mason Mark McCullough says that new mortar adheres to the brick rather than to existing mortar, which is why thorough removal is critical. This typically amounts to about 3/4 inch in depth.
Prepare the new mortar according to the manufacturer’s instructions, ensuring the mix is consistent and suited to the existing material.
Use a pointing hawk and tuckpointing trowel to carefully apply the new mortar to the joints you’ve cleaned out. Start with the horizontal joints, then move on to vertical joints. The goal is to achieve smooth, straight lines that match the existing mortar pattern.
Allow the mortar to set slightly, then use a jointing tool to create the finish you want. Clean any excess mortar from the brick faces with a stiff-bristled brush. The new mortar will need between 36 and 48 hours to cure completely, depending on weather conditions.
DIY Tuckpointing vs. Hiring a Professional
Whether you tackle tuckpointing yourself or hire a professional depends on the size of the project, your experience level, and the condition of the masonry.
Tuckpointing can be time-consuming and physically demanding, especially on large surfaces or areas that are difficult to reach. Because the process involves removing and replacing mortar, mistakes can be difficult to correct once the material begins to set.
Inexperienced do-it-yourself (DIY) work can also lead to poor adhesion, mismatched mortar, or joints that fail prematurely, which may require more extensive repairs later.
When To Call in the Experts
Consider hiring a professional tuckpointing contractor if any of the variables below apply.
- The project is large-scale or complex.
- The work involves hard-to-reach areas such as chimneys or high walls.
- You lack the time or necessary skills to complete the job properly.
- You’re dealing with a historic or high-value property.
Professional masons have the expertise necessary to complete the job well, and usually offer warranties on their work, which affords homeowners peace of mind.
Tuckpointing Costs and Factors
Tuckpointing costs can vary widely depending on the size of the project, the condition of the masonry, and the accessibility of the work area.
Material Costs
The price of mortar, pigments, and any necessary tools can add up. High-quality materials may cost more upfront but can lead to better, longer-lasting results.
Labor Costs
The cost of mortar, pigments, and tools can add up, especially if you’re using higher-quality materials designed to match existing brickwork and improve durability.
Regional Price Variations
Costs may also vary based on location, with higher prices in urban areas or regions with a higher cost of living. Tuckpointing typically costs between $10 and $45* per square foot, depending on these factors. Costs can also increase if the masonry is severely deteriorated, if the work involves tall structures like chimneys, or if specialized materials are required to match historic brick.

Common Tuckpointing Mistakes To Avoid
Tuckpointing requires careful preparation and attention to detail. Small mistakes can lead to weak joints, poor adhesion, or premature failure of repairs.
Incorrect Mortar Mix
Using the wrong type of mortar or incorrect mix ratios can lead to poor adhesion and long-term damage. It’s important to match the new mortar to the existing material, especially on older brick.
Poor Joint Preparation
If old mortar is not fully removed or the joints are not properly prepared, the new mortar may not bond effectively. McCullough explains on a segment of Ask This Old House that failing to properly prepare the brick can cause problems: “If you skip that step, the moisture gets sucked out of the mortar as it dries, and you’re left with what we call dusty mortar. This can lead to weak joints that crumble over time and require additional repairs.”
Improper Application Techniques
Applying mortar too thickly or too thinly, or failing to properly tool the joints, can affect both the appearance and durability of the repair. Poor application can also allow water to infiltrate the wall.
Maintenance Tips To Extend the Life of Your Tuckpointing
Regular maintenance can help extend the life of your tuckpointing and prevent more extensive masonry repairs.
- Inspect regularly: Check your brickwork for cracks, crumbling mortar, or signs of moisture damage. Catching issues early can prevent water from penetrating deeper into the structure.
- Keep surfaces clean: Use gentle cleaning methods to remove dirt and debris without damaging the mortar, and prevent buildup that can trap moisture against the wall.
- Protect against moisture: Consider applying a breathable sealant to help reduce moisture infiltration while still allowing the brick to breathe.
- Schedule professional inspections: Periodic evaluations can help identify potential problems before they worsen.
