Hiring a Masonry Contractor? Ask These Questions First

Masonry work -- brick, stone, and block -- requires craft skills that take years to develop. The difference between good and poor masonry is visible for decades, since these materials are designed to last a lifetime. Mortar color matching, consistent joint width, and proper drainage behind walls are the details that reveal whether you're talking to a genuine craftsman or someone who stacks blocks and hopes for the best.

8 QuestionsPrintable ChecklistAvg Cost: $500 - $5,000 per job

Questions to Ask

1Are you licensed and insured for masonry work in this state?

Why It Matters

Masonry is a specialty trade that requires specific skills. A general contractor without masonry experience may not understand proper mortar chemistry, flashing requirements, or structural considerations.

Red Flag

They hold only a general contractor license with no masonry-specific experience or training.

Pro Tip

Ask about their specific masonry experience, not just their license type. Years of experience matter significantly in a craft-heavy trade like masonry.

2Can you match the existing mortar color and joint style on my repair project?

Why It Matters

Mismatched mortar on a repair job looks terrible and is permanent. Mortar color matching requires understanding mortar chemistry and sometimes custom mixing to achieve a visual match.

Red Flag

They plan to use standard gray or white mortar without attempting to match existing mortar color and profile.

Pro Tip

Ask to see samples or photos of previous color-matching work. A skilled mason will test mortar samples and let them cure before committing to a color match on your wall.

3Will you pull the necessary permits for this project?

Why It Matters

Structural masonry work, retaining walls over 4 feet, and chimney rebuilds typically require permits and inspections.

Red Flag

They dismiss permits as unnecessary for structural masonry work.

Pro Tip

Even for non-structural work, check your local requirements. Some jurisdictions require permits for any exterior modification.

4Which mortar mix are you selecting for this project, and how did you decide between Type N, S, and M?

Why It Matters

Mortar types have very different compressive strengths and flexibility. Type M is strongest but brittle -- using it on an older brick wall can crack the softer bricks as they expand and contract. Type N is weaker but more flexible, making it appropriate for above-grade walls and historic restoration.

Red Flag

They use one mortar type on every job without considering the age, hardness, or type of masonry units involved.

Pro Tip

For repairs on homes built before the 1920s, lime-based mortar is typically the right choice. Portland cement mortar is too rigid for soft, handmade bricks and will cause spalling. Ask the mason to explain the specific mix ratio they plan to use.

5What guarantee do you provide against settling or cracking in the first few years?

Why It Matters

Masonry settling and mortar joint cracking can take 6 to 24 months to appear, well after the project looks finished. These failures often indicate problems with the footing, subgrade preparation, or mortar mix rather than normal aging.

Red Flag

They offer no warranty that specifically covers settling or structural cracking, or they dismiss early cracking as expected behavior.

Pro Tip

A strong masonry warranty covers structural cracking (not just hairline cosmetic cracks), mortar joint failure, and settling for at least two to five years. Ask whether the warranty includes a return visit to inspect and repair at no cost.

6For retaining walls, how will you handle drainage behind the wall to prevent hydrostatic pressure buildup?

Why It Matters

Water pressure behind a retaining wall is the primary cause of wall failure. Without a drainage system, water saturates the soil behind the wall, builds pressure, and eventually pushes the wall over or causes it to bow.

Red Flag

They plan to build a retaining wall without gravel backfill, drain tile, or weep holes.

Pro Tip

Proper retaining wall drainage includes a perforated drain pipe at the base, 12 or more inches of clean gravel backfill behind the wall, filter fabric to prevent soil from clogging the gravel, and weep holes at the base every 4 to 6 feet.

7Can you show me photos of completed projects similar to mine?

Why It Matters

Masonry quality is visual. Photos reveal joint consistency, color matching, and overall craftsmanship that tells you more than any sales pitch.

Red Flag

They have no portfolio of completed work.

Pro Tip

Ask to drive by a recent project in person. Masonry work is exterior and visible -- you can evaluate quality from the street.

8How do you handle tuckpointing and repointing to preserve the original character of the masonry?

Why It Matters

Tuckpointing (replacing deteriorated mortar joints) requires removing old mortar to the correct depth without damaging bricks, then filling with properly matched new mortar. Done wrong, it damages bricks and looks worse than before.

Red Flag

They plan to use power tools to grind out mortar joints in soft or historic brick, which can crack and damage the brick faces.

Pro Tip

Hand tools or carefully controlled oscillating tools are preferred for mortar removal on historic or soft brick. Power grinders should only be used on hard modern brick with wide joints.

Bonus Tips for Hiring a Masonry Contractor

  • Before approving a mortar color for repointing, ask the mason to prepare a test patch and let it cure for at least 48 hours. Wet mortar looks completely different from cured mortar, and mismatches are permanent.
  • If your project involves a chimney, confirm the mason inspects the flue liner and crown as part of the scope. A rebuilt chimney exterior with a cracked liner or deteriorated crown still leaks and poses safety risks.
  • Ask whether the mason will protect finished masonry from rain during the first 24 to 48 hours of curing. Fresh mortar joints washed out by rain must be redone entirely.
