Choosing the Right Stone for Your Exterior
Selecting the right exterior stone is not just a design decision — it’s a structural and safety decision. At Met Exteriors, we regularly see projects where the wrong material or improper installation leads to premature failure, costly repairs, and serious safety risks.
Don’t Choose Stone Based on Price Alone
One of the most common mistakes homeowners and builders make is choosing the cheapest stone product available. While this may reduce upfront costs, it often results in:
- Bonding and adhesion failures
- Cracking and moisture penetration
- Loose or falling stone
- Expensive repairs or full replacement
We have inspected many residential and commercial buildings where exterior stone has separated or fallen, creating the risk of property damage and personal injury.
Not All Stone Is Suitable for Exterior Use
Many stone products on the market are not engineered for exterior applications, especially in Alberta’s demanding climate. Some materials suffer from:
- Poor manufacturing quality
- Inconsistent thickness or backing
- Inadequate bonding surfaces
Before selecting any stone, confirm that the product is approved for exterior use and designed to perform in freeze-thaw conditions.
Proper Installation Is Critical
Even the highest-quality stone will fail if it’s installed incorrectly. Common installation issues include:
- Using improper mortar or adhesive systems
- Skipping required mechanical support or lath
- Inadequate substrates and moisture barriers
- Ignoring manufacturer installation guidelines
Exterior stone installation must comply with manufacturer specifications and local building code standards. Cutting corners during installation almost always leads to failure.
Verify Code Compliance and Installation Guidelines
Always:
- Request official installation guidelines from the supplier
- Confirm the system meets local building code requirements
- Ensure all materials are compatible as a complete system
