A masonry project's final inspection separates amateur work from skilled craftsmanship—and protects your investment. Poor brickwork, mortar joints, or stone placement can lead to water infiltration, structural failure, and expensive repairs down the road. Knowing what to assess before signing off ensures you're paying for quality.
What to Check Before Final Approval
Don't rely on visual impressiveness alone. Schedule your final walkthrough when the project is complete but before you make the final payment. Bring the original contract, take photos, and spend at least 30-45 minutes examining the work systematically rather than rushing through.
The best time to catch problems is before funds are released. Once your masonry contractor has been fully paid, motivation to fix issues drops significantly.
Inspect Mortar Joints and Pointing
Mortar joints are the skeleton of brickwork—they bond units together and seal against weather. Examine joints closely for consistency, depth, and finish quality.
Look for these red flags:
- Inconsistent joint width: Standard joints should be ⅜–½ inch thick and uniform throughout the wall
- Voids or gaps: Missing mortar creates pathways for water and reduces structural integrity
- Proud joints (mortar protruding beyond the brick face): Sign of poor tooling and future water problems
- Recessed joints deeper than ¾ inch: Weakens the wall and collects moisture
- Color variation: While minor variation is normal, stark differences suggest inconsistent mortar batches or cure times
Run your finger across joints to check for loose material. Properly cured mortar (typically 7–14 days after application) should resist scratching with a coin or key.
Evaluate Brick and Stone Placement
Each masonry unit should be fully bedded in mortar with no hollow spots underneath. Tap bricks with a rubber mallet—a hollow sound indicates poor bond, which compromises structural strength and weather resistance.
Check for:
- Alignment and plumb: Use a level or long straightedge to verify vertical and horizontal lines match the design
- Spacing consistency: Brick coursing should maintain straight lines without stair-stepping or waviness
- Unit damage: Look for cracks, chips, or spalling (flaking surface) that compromise appearance and durability
- Bond pattern fidelity: Verify the contractor followed the specified pattern (running bond, Flemish, stack bond, etc.)
Slight variations in natural stone are expected, but they shouldn't create visible discontinuity in your finished surface.
Check Water Penetration Prevention
Water infiltration is the leading cause of masonry failure. On exterior walls, inspect:
- Weep holes: Small openings near the base of walls allow trapped moisture to escape; they should be visible and unobstructed
- Flashing installation: Metal or synthetic flashing at transitions (rooflines, window sills, grade changes) should sit flush with masonry without gaps
- Caulking quality: Sealed joints should be smooth, consistent, and properly adhered without gaps or voids
- Slope and drainage: Exterior surfaces should slope away from the building to direct water downward, not into foundation areas
Run water tests on exterior walls (if your contractor permits) or inspect after rain to confirm no moisture seeps inside.
Verify Structural Integration
For load-bearing masonry or structural repairs, the work must tie into existing walls properly:
- Bonding: New work should interlock with old masonry using proper bond patterns rather than simply abutting the surface
- Grout filling: Cavities in block or stone construction should be fully grouted in structural applications (no voids)
- Reinforcement: Verify steel rebar or mesh placement matches specifications, particularly at corners and above openings
Request a structural inspection report if this was part of the contract—your masonry contractor should be able to provide documentation of how the work meets building codes.
Documentation and Sign-Off
Before releasing final payment, confirm:
- The contractor has cleaned the workspace completely (no mortar splatter, leftover materials, or debris)
- All touch-ups and punch-list items are finished
- You have before-and-after photos for your records
- The warranty documentation is in writing (typical masonry warranties run 1–5 years)

Frequently Asked Questions
Q: How long should I wait before inspecting a masonry project? Wait at least 7–14 days after completion to allow mortar full cure time, which lets you accurately assess joint quality and structural integrity without risking premature damage during inspection.
Q: What's a reasonable cost for fixes if the contractor missed details? Minor touch-ups (small voids, color correction, caulking) should be included at no charge; however, major issues like rebedding loose bricks or re-pointing extensive sections could cost $10–$30 per square foot depending on scope and access.
Q: Should I hire a third-party inspector for a large masonry project? For projects exceeding $25,000 or structural work, a certified mason inspector ($400–$800) provides independent assessment and protects you if disputes arise about workmanship.
