Pointing is the silent workhorse of brick and stone masonry—the mortar between your exterior walls that keeps weather, moisture, and structural problems out. When pointing fails, water infiltrates, bricks shift, and repair costs multiply fast. Here's what you need to know about pricing, timing, and when to call a professional.
What Is Pointing and Why It Matters
Pointing refers to the process of filling or refilling the mortar joints between bricks, stones, or blocks. Over time—typically 25 to 40 years depending on climate and mortar quality—these joints crack, crumble, and recede. Rain and freeze-thaw cycles accelerate deterioration. If you ignore failing mortar, water gets behind the facade, damages internal walls, rots framing, and creates structural damage that costs five to ten times more to fix than pointing would have.
Typical Pointing Costs
Per square foot: $5 to $25 depending on accessibility, brick type, and location.
Full chimney: $500 to $2,500.
Entire home exterior: $3,000 to $15,000+ for a modest two-story house.
Factors that raise costs:
- Difficult access (high peaks, steep roofing)
- Historic or specialty brick requiring matched mortar
- Deep deterioration requiring full repointing rather than surface work
- High-labor markets in urban areas

Signs Your Brick or Stone Needs Pointing
Don't wait for visible water damage inside. Look for these red flags on your exterior:
- Recessed or missing mortar (joints visibly sunken or hollow)
- Crumbling or powdery mortar that crumbles when you press it with a tool
- Cracks wider than 1/4 inch running through joints
- Efflorescence (white, chalky staining) indicating water migration
- Loose bricks that shift slightly when pushed
- Visible gaps where mortar has completely separated from brick edges
If you spot any of these, get a professional assessment before moisture damage spreads.
What a Professional Pointing Job Involves
A quality repointing project includes:
- Assessment: Contractor examines mortar condition, identifies failed areas, and tests mortar strength with simple tools
- Mortar matching: Existing mortar is sampled and analyzed to match color, composition, and hardness (critical for historic masonry)
- Joint preparation: Old, loose mortar is raked out to a depth of 2.5 times the joint width
- New mortar application: Fresh mortar is packed firmly into joints using hand tools or specialized equipment
- Tooling and cleanup: Joints are shaped and excess mortar is removed for a finished appearance
- Curing: Work is protected from rain and excessive heat while mortar sets (typically 7–14 days)
Rushing any step compromises durability.
DIY vs. Professional: What You Should Know
Skip DIY if:
- You have more than a few square feet of deteriorated mortar
- The work is on high, steep, or hard-to-access areas
- Your bricks are historic, handmade, or require specialty mortar
- You're uncertain about mortar composition
DIY is reasonable if:
- You have small, isolated problem areas on low walls
- You've confirmed mortar type and sourced matching material
- You're comfortable working on ladders and scaffolding
Most homeowners should hire professionals. A bad repointing job traps water or creates harder mortar that damages softer historic brick—problems that cost thousands to correct.
Timeline and Scheduling
A typical repointing project takes 2 to 4 weeks depending on scope and weather. Summer and early fall are peak seasons; expect longer waits and potentially higher pricing. Winter work is difficult because mortar doesn't cure properly in cold, wet conditions. Plan ahead if you're targeting a specific season.
Finding and Comparing Contractors
Look for:
- Masonry-specific experience (not general handymen)
- References from recent pointing projects (ask to see photos before and after)
- Proof of insurance and licensing
- Written specifications on mortar type, joint depth, and cleanup
- Warranty (legitimate contractors stand behind their work for 5–10 years)
Platforms like Mercoly help you compare and find trusted brick and masonry specialists in your area, making it easier to gather quotes and vet contractors without endless research.
Frequently Asked Questions
Q: How do I know if my mortar matches what's already in place? A: A professional mortar analysis compares the old mortar's color, sand grain size, and hardness to ensure new mortar bonds properly and moves with your masonry rather than against it. Mismatched mortar causes accelerated brick damage.
Q: Can I just caulk cracks instead of repointing? A: No—caulk is flexible and temporary; it doesn't provide structural support or durability. Mortar is a structural material that fills the full joint depth and bonds brick together. Caulking is a band-aid that delays the real fix.
Q: What's the difference between repointing and tuck-pointing? A: Tuck-pointing fills surface cracks only; repointing removes and replaces mortar throughout the full joint depth. Repointing is the proper solution for aged or deteriorated masonry.
