Pointing Brick Wall: Cost, Tools, and a Step-by-Step Repair Guide

Pointing a brick wall — also called repointing or tuckpointing — is the process of scraping out failing mortar joints and packing in fresh mortar. It is the single most effective repair you can make to a masonry wall before the damage spreads, and it is one of the few exterior jobs a careful homeowner can tackle on a weekend. Done right, fresh pointing keeps water out, stops bricks from loosening, and adds years to the life of a wall or chimney.

Left alone, cracked and crumbling mortar turns a cosmetic problem into a structural one. Water works its way into the open joints, freezes, and pries the joints wider every winter. The bricks themselves become the weak point once the soft, sacrificial mortar stops doing its job. The good news is that the fix is straightforward if you match the right mortar and work in the right conditions.

This guide covers what pointing costs, which tools and mortar you need, and how to do the job step by step so it holds up for decades.

Why Brick Mortar Fails in the First Place

Mortar is designed to be softer and more porous than the brick around it. That is intentional. The joint absorbs movement, lets trapped moisture evaporate, and cracks before the far more expensive brick does. Eventually, though, every mortar joint reaches the end of its service life.

The most common reasons mortar fails on an exterior wall include:

• Freeze-thaw cycles. Water soaks into tiny gaps, freezes, and expands by roughly 9 percent. Repeated cycles gradually crumble the surface of the joint.
• Ground movement and settling. Foundation shifts put pressure on rigid walls, cracking the joints in a stair-step pattern rather than in the bricks.
• Wrong mortar mix. A mortar that is harder than the brick traps moisture in the masonry. Older lime mortars (common pre-1930) need a soft, breathable repoint mix, not a hard Portland-cement patch.
• Pressure washing done wrong. A high-pressure blast aimed at old joints can blow out decades of mortar in an afternoon. If you have cleaned the wall aggressively, that damage often shows up as sand and grit on the ground below.
• Vegetation and poor drainage. Ivy roots, overflowing gutters, and soil piled against the wall keep joints wet enough to fail early.

The first sign is nearly always visual. Look for hairline cracks in the joints, mortar that has pulled away from the brick edges, or joints that crumble when you run a flathead screwdriver across them. A joint that erodes more than about 1/4 inch deep is a candidate for repointing.

How to Point a Brick Wall: Tools, Mortar, and Prep

Before you mix a single batch of mortar, you need to know what type of wall you are dealing with and stage the right materials. Skipping prep is the fastest way to end up with a patch job that flakes out in two years.

Match the Mortar First

Mortar mismatch is the most common cause of early repoint failure. The rule is simple: the new mortar should be no harder than the old mortar, and never harder than the brick. For most homes built before the 1930s, that means a lime-and-sand mortar (often measured as a “1:3 lime-to-sand” mix) rather than a modern Type N or Type S cement mortar.

For homes built in the last several decades, a standard Type N mortar is usually a safe match — it is the middle-ground mix used for general exterior wall work. For repairs below grade or on retaining walls, Type S offers higher compressive strength. If you are unsure, have a small sample of the original mortar analyzed, or have a local masonry supplier recommend a pre-blended repointing mortar. Brands such as Quikrete Mortar Mix, Spec Mix, and US Heritage Group repointing mortars are widely available and take the guesswork out of mixing ratios.

Choose the Right Weather Window

Mortar cures through hydration, which means it needs moderate temperatures and moisture to set properly. The ideal conditions are:

• Air and wall temperature between 50°F and 90°F (10°C to 32°C).
• No direct, blazing sun on the fresh joints, which can flash-dry them before curing.
• No rain in the 24 hours before or after application.
• Wall surface slightly damp but not wet when you work.

On a hot summer day, that often means working a shaded wall and lightly misting the joints as you go.

Assemble the Tools

A full repointing setup does not require much beyond basic masonry hand tools. The essentials:

• Masonry grinder with a tuckpointing blade (or an angle grinder with a 1/4-inch diamond blade) for cutting out old mortar cleanly.
• Cold chisel and hammer for hand removal on small areas or soft, historic mortar.
• Pointing trowel and a tuck pointer (a narrow, flat trowel made for packing joints).
• Jointer tool (also called a slicker) sized to match the existing joint width.
• Stiff-bristle brush or compressed air to clean dust from the cut joints.
• Mixing tub, hoe, and drill-mounted paddle mixer for a consistent mortar batch.
• Misting bottle or pump sprayer to keep joints and the wall damp.
• Safety gear: goggles, an N95 or P100 respirator (silica dust is a real hazard), and hearing protection for grinding.

How Much Does Pointing Brick Wall Cost?

Pointing a brick wall is priced per square foot of wall face, not per brick. The national range for professional repointing in the US sits between roughly $5 and $15 per square foot, with most exterior jobs landing near $8 to $12 per square foot. On a typical two-story brick elevation of about 400 square feet, that puts the pro cost between $3,000 and $5,000, with taller scaffolding, chimneys, and difficult access pushing the price toward the top of the range.

Doing it yourself drops the material cost dramatically. Bagged mortar runs $8 to $15 per 60- to 80-pound bag, and a single bag repoints roughly 30 to 40 square feet of average wall depending on joint size and depth. Add a diamond grinding blade ($25 to $60) and basic hand tools, and most DIY repointing projects land under $500 in materials, even for a sizable wall.

Cost factors worth planning around:

• Wall height and access. Anything above one story typically needs scaffolding, which adds labor and rental cost.
• Joint condition and depth. Heavily eroded joints need deeper cutting and more mortar, raising both time and material use.
• Historic or soft brick. Older homes often require custom lime mortar and a slower, hand-tool-only removal process, which costs more.
• Your region. Labor rates in the Northeast and on the West Coast run higher than in the Midwest or South.

Step by Step: Pointing the Joints

The mechanics are straightforward, but the quality lives in the details. Work in sections small enough that your mortar does not set before you finish the joint.

1. Cut out the old mortar. Grind each vertical (head) joint first, then the horizontal (bed) joints, to a uniform depth of about 3/4 inch, or at least twice the joint width. Keep the grinder steady so you do not notch the brick edges. On historic brick, skip the grinder and use a chisel to avoid chipping soft faces.
2. Clean the joints. Brush or blow out every trace of dust and loose material. Dust left in the joint prevents the new mortar from bonding.
3. Dampen the wall. Lightly mist the joints so the dry brick and old mortar do not suck water out of the fresh mix too fast. The surface should be damp, not dripping.
4. Mix the mortar. Aim for a stiff, workable consistency — about the texture of peanut butter. Mix only as much as you can use in 30 to 45 minutes, and let it sit (“slake”) for a few minutes before use.
5. Pack the joints. Load mortar onto the tuck pointer and press it firmly into the head joints first, then the bed joints, building up in thin layers on deeper joints rather than one thick glob.
6. Tool the surface. Once the mortar is firm (thumbprint-soft but no longer sticky), run the jointer over each joint to compress it and match the existing profile — concave, V, or flush. Tooling pushes the mortar tight against the brick and sheds water.
7. Cure it slowly. Mist the finished section lightly two or three times a day for the next three days, especially in warm, dry, or windy weather. Slow curing is what builds strength and prevents cracking.

Common Mistakes That Ruin a Pointing Job

Even with the right plan, a few errors quietly undo most amateur pointing work.

• Using the wrong mortar hardness. A hard cement patch on soft brick forces moisture through the brick itself, causing the brick faces to pop off (spalling) — a far costlier repair than the original repoint.
• Shallow joints. Cutting less than 3/4 inch deep leaves the new mortar too thin to hold and it falls out in a season or two.
• Working in full sun or high heat. Flash-dried mortar never reaches full strength and cracks almost immediately.
• Raking joints flat and leaving them. An untooled joint is porous and weak along its surface; a properly tooled concave joint sheds water far better.
• Pointing over dust or dry brick. Mortar needs a clean, damp substrate to bond. Skipping cleanup is the leading cause of hollow, loose joints.
• Ignoring the actual water problem. If a leaking gutter, missing flashing, or failed caulk is what soaked the wall in the first place, fresh pointing will erode again until you fix the source. Check nearby exterior caulking and downspout drainage before you call the wall done.

Repoint It Yourself or Hire a Mason: How to Decide

Repointing is genuinely doable for a confident DIYer, but it is repetitive, dusty work that punishes rushing. The honest read is that small, ground-level sections are fine to tackle yourself, while big or risky jobs are better left to a pro.

DIY is reasonable when: the area is small (a few square feet up to a single wall section), accessible without scaffolding, built with modern brick, and you can match the mortar readily. A weekend and $200 to $500 in materials are usually enough to make a real, lasting difference.

Call a mason when: the wall is taller than a single story, the damage is widespread or structural (bulging, cracked bricks, not just cracked joints), the home is historic with soft brick, or a chimney is involved. Chimneys in particular are worth professional attention — vertical work, height, and weather exposure combine to make mistakes costly. In those cases, the $8-to-$12-per-square-foot professional rate buys you a job that is actually done to last 30 to 50 years.

Whichever route you take, weatherproofing the wall after the mortar cures goes a long way. Make sure water is moving away from the wall — see our guide on how to pressure wash a house for safe cleaning, and weatherstripping window and door seams to stop drafts and moisture at the edges.

Frequently Asked Questions

How often does a brick wall need repointing?
A properly done repointing job with matched mortar lasts 30 to 50 years on most homes. Walls in harsh climates with heavy freeze-thaw cycles may need touch-ups sooner, while sheltered walls can go far longer.

Is repointing the same as tuckpointing?
Almost. Repointing refers to replacing the mortar joints themselves. Tuckpointing is the practice of cutting a fine, contrasting line into fresh (or stained) mortar to make the joints look crisper and thinner — common on historic brickwork. The terms get used interchangeably by most contractors.

Can I repoint a brick wall in winter?
Only if temperatures stay consistently above 40°F during application and for several days of curing, which rules out most cold-climate winter work. Mortar that freezes before it cures loses nearly all of its strength.

Will pressure washing damage my brick joints?
Yes, if done carelessly. A high-pressure stream aimed directly at old, soft joints can blow out mortar in minutes. Use lower pressure, wider fan nozzles, and keep the spray moving — or clean the wall with a soft wash instead.

How do I match the mortar color on an older wall?
Take a chip of the existing mortar to a masonry supply yard and match against their sample board. Color differences from sand source and cement content are usually close enough; test a small, inconspicuous patch first and let it cure before committing to the whole wall.

The Bottom Line

Pointing a brick wall is the highest-value repair you can make to aging masonry. For a few hundred dollars in materials or a few thousand on a pro’s invoice, you stop water intrusion at its source, protect the bricks themselves, and extend the life of the wall by decades. The keys are matching the mortar to the brick, cutting joints to the proper depth, and giving the fresh mortar time to cure slowly.

If the joints on one wall are starting to crumble, do not wait for the bricks to follow. Fix the drainage, match the mortar, and get the joints pointed before the next freeze-thaw season. Whether you grind it out yourself or bring in a mason, a properly pointed wall is one of the quietest, most durable improvements you can make to the outside of your home.
