Jointing and pointing are two terms masons use every day, yet homeowners often mix them up. Knowing which is which saves money, prevents cracks, and keeps walls weather-tight.
Jointing happens while the mortar is still fresh and pliable. Pointing is the later repair or finish work done after the wall has hardened. Each process needs different tools, timing, and skills.
What Jointing Really Means on Site
The Fresh-Mortar Stage
Jointing is the first shaping of the joints right after a brick or stone is laid. The mason strikes or profiles the still-soft bed and perpend joints to compact them and create the chosen finish.
This single action locks the units together and starts the controlled curing cycle. A well-jointed wall needs less later maintenance because the mortar density is already high.
Standard Joint Profiles
Common choices include flush, bucket-handle, weather-struck, and recessed. Each profile changes how water runs off the face and how shadows define the brickwork pattern.
Flush joints sit level with the brick face and are quickest to produce. Bucket-handle forms a concave groove that sheds rain and hides small irregularities.
Tools That Shape the Joint
A single steel jointer, sometimes called a “striker,” is pressed along the mortar. The profile of that tool determines the final contour and also compresses the surface, reducing future shrinkage cracks.
Timing and Weather Concerns
Jointing must be done before the mortar stiffens but after it has lost its wet sheen. Hot sun or strong wind can skin the surface too fast, forcing the mason to mist the wall and keep the joint workable.
What Pointing Actually Involves
The Later-Care Stage
Pointing is the removal of old or damaged mortar to a shallow depth and the insertion of fresh mortar in its place. It is a remedial action, not part of the original build.
The new mortar is tightly packed and then trimmed to match the original joint profile. Done well, it extends wall life by decades without rebuilding.
When Walls Call for Pointing
Fine cracks, hollow spots, or sandy mortar indicate that pointing is due. If rainwater disappears into the joint instead of beading on the surface, the bond has broken down.
Cutting Out Old Mortar
Craftsmen use hand chisels or small angle grinders to rake out joints to roughly twice the joint width. Dust is brushed away and the slot dampened so the new mortar grips instead of drying too fast.
Mixing and Placing Fresh Mortar
The repointing mix is often slightly richer in cement or lime than the original to gain early strength. It is pushed in layers, allowed to thumb-print hard, and then trimmed to the chosen profile.
Key Differences in Purpose
Jointing is about birth; pointing is about upkeep. One creates the finish, the other restores it.
Jointing decides how the wall will look and perform from day one. Pointing fixes what time and weather have undone.
Material Choices for Each Task
Jointing Mortar Basics
The same mortar used to lay the brick is usually adequate for jointing. Adding a touch more lime can improve workability for ornate profiles.
Pointing Mortar Tweaks
Repointing mixes often use well-graded sand and a pinch more cement to speed set in narrow slots. Lime remains valuable for elasticity in older buildings that flex slightly.
Color Matching Secrets
Pointing sand is sieved through a fine mesh so the grain size mimics the original joint. A wet mock-up on a spare brick lets the mason adjust pigment before touching the wall.
Tools That Separate the Two Jobs
Jointing requires only the striker and perhaps a small brush. Pointing demands raking tools, pointing trowels, hawk boards, and sometimes specialist guns for tight spots.
A pointing trowel has a narrow blade to push mortar deep into the raked slot. Jointing tools are rounded or profiled to shape, not to fill.
Skill Levels and Learning Curves
Jointing Speed and Rhythm
An apprentice can learn to run a consistent bucket-handle joint within a few days. The trick is matching the striker angle to the mortar stiffness.
Speed matters because the wall keeps rising; slow jointing leaves witness lines where fresh bricks meet stiffened mortar.
Pointing Precision and Patience
Pointing is slower and unforgiving; a single smear on the brick face can stain. Craftsmen often cut the final surface with a special pointer trowel to leave a crisp edge.
Cost Implications for Homeowners
Jointing is bundled into the bricklayer’s rate, so it rarely appears as a separate line item. Pointing is priced by the meter or by the day, and access height can double the figure.
Patch-pointing a few eroding joints can be a small-budget fix. Full-house repointing may rival the cost of a new roof because it is labor-heavy and slow.
Weather Performance Over Time
A well-jointed wall starts life with compressed, water-shedding surfaces. If the original profile is shallow, rain can sit and freeze, hastening the need for pointing.
Repointing with the wrong mortar—too hard or too soft—can trap moisture and spall the brick. Matching strength and porosity keeps the wall breathing as one unit.
Visual Impact on Brickwork
Jointing sets the visual rhythm; crisp, consistent joints make even cheap bricks look tidy. Pointing can refresh that rhythm, but color mismatches stand out like patchy paint.
Recessed pointing on an old cottage can create dramatic shadows, yet the same style on a modern facade may look busy. Choosing a profile that suits the era keeps the character intact.
Common DIY Pitfalls
Jointing Too Early or Late
Striking mortar while it bleeds water smears lime onto the brick face, leaving haze. Waiting until it is rock-hard creates rough, cracked edges that never look uniform.
Pointing Without Adequate Depth
Skimming new mortar over the old is a short-term cosmetic fix. Within a season, frost pops the thin layer off and the wall looks worse than before.
Wrong Mortar Recipe
Strong modern cement on soft Victorian brick accelerates cracking. A leaner, lime-rich mix forgives slight movement and keeps the wall supple.
Professional Tricks Worth Borrowing
Pros joint in shaded sections and rotate the scaffold so the sun never bakes one face. They keep a damp sack over the mortar board to slow set on hot days.
For pointing, they pre-cut a test patch and photograph it so the client approves color and width. This single step prevents costly re-dos.
Maintenance Planning
Inspect joints every spring for hairlines and every autumn for moss. Spot-pointing tiny failures now avoids wholesale raking later.
Keep gutters clear; overflow water is the fastest route to ruined pointing. A day of ladder work can save years of mortar life.
