Many homeowners, and even some masons, don’t realize that stone should be laid according to specific masonry principles. Homeowners may sketch out ideas for their walls, thinking a pattern looks great, while inexperienced masons may come up with a unique design and wonder, “Why hasn’t anyone done this before?” However, masonry is both an art and a science—more than just stacking stones and hoping they hold.
For centuries, master masons have relied on time-tested patterns to build durable structures. Just look at medieval castles and cathedrals; the patterns that worked have stood the test of time, while weaker designs have long been abandoned. While modern stonework is typically a veneer rather than structural, proper patterning remains essential.
The Importance of Stone Patterns
Stone is a natural product with individual pieces that vary in shape and size. Whether cut, chopped, or random, they must be laid in a predefined pattern to ensure strength and integrity. Factors like load shifting, settling, and displacement all impact stonework, and a well-chosen pattern mitigates these risks.
That said, following masonry rules doesn’t mean you’re stuck with a boring, cookie-cutter design. There are many acceptable ways to lay stone, from random patterns to staggered brick-like arrangements. The key is to choose a design that suits your style while ensuring longevity.
Common Stonework Mistakes to Avoid
Ignoring masonry principles can result in anything from unsightly cracks to outright failure, with stones falling out of place. Here are some of the most common errors I see:
Tombstones – Stones laid vertically. No stone should be taller than it is long.
Stack Bond – Stones stacked directly on top of one another with no staggered joints.
Long Vertical Joints – Continuous vertical lines weaken the structure.
Pistols – Stones arranged in a way that resembles pistols, creating weak points.
These mistakes compromise the bond between stones and lead to structural failure. Remember, stone is not brick or tile and should not be treated as such.

Choosing the Right Mason
How do you ensure you hire a skilled mason? Vet every subcontractor, including your mason, by checking references and reviewing their portfolio. A mason’s past work will reveal their understanding of proper stone patterns. Additionally, ask around and inspect completed projects before making your decision.
If you like a pattern but your mason advises against it, listen to them—it’s their reputation on the line.
A Note for Masons
What if a homeowner insists on vertical placements or large joints? Educate them on why these choices are problematic. If they still insist, you must decide whether to take the job. If you do, consider having them sign a waiver releasing you from responsibility for the integrity of the work and voiding any warranties.
In Conclusion, Masonry is not just about aesthetics; it’s about building something that lasts. A well-laid stone wall can endure for generations, but only if it follows established principles. Whether you’re a homeowner or a mason, understanding and respecting these rules ensures your investment in stonework stands strong for years to come.
