The 7 Most Common Signs Your Stone Veneer Needs Repair
1. Cracks or Gaps in the Surface
Cracks are one of the most common signs. Small hairline cracks may seem harmless, but they can grow with time and allow the moisture to get in. Larger gaps might indicate poor installation or foundation movement. Water entering through cracks can cause mold, mildew, and even damage behind the stone.
What to Do:
- Inspect cracks regularly to monitor any growth.
- Seal minor gaps with masonry caulk or sealant.
- Call a professional if cracks widen or reveal deeper issues.
2. Loose or Falling Stones
Are the stones moving or falling off? This often happens due to failing mortar, poor installation, or weather-related wear. Loose pieces not only look unsightly but also dangerous.
What to Do:
- Avoid attempting to fix loose stones yourself.
- Secure the area to prevent accidents.
- Hire a masonry expert to properly repair or replace damaged sections.
3. Discoloration or Staining
Stains or color changes on veneer often indicate moisture problems. A white, powdery residue (efflorescence) appears when water evaporates, leaving mineral deposits. While rusty patches may indicate corroding metal components within the wall, dark streaks may be an indication of mold or mildew.
What to Do:
- Clean surface stains with a gentle masonry cleaner.
- Investigate persistent stains for hidden leaks.
- Get a professional inspection to address moisture sources.
4. Bulging or Warping Veneer
When sections of the veneer appear to push outward, it often means trapped moisture or failing backing materials. If left unchecked, this can cause sections to detach completely.
What to Do:
- Do not press or lean on bulging areas.
- Schedule a professional inspection promptly.
- Repair problems early to avoid costly rebuilds.
5. Mortar Deterioration
Mortar holds the veneer together, but it doesn’t last forever. Crumbling, powdery, or missing mortar joints weaken the structure and cause water damage. Repointing (replacing old mortar) is necessary to restore stability.
What to Do:
- Check mortar joints annually for cracks or gaps.
- Repair small areas with DIY repointing if confident.
- For extensive damage, hire a mason to ensure a durable fix.
6. Water Leaks Inside the Home
If walls near the veneer feel damp or show water stains, the exterior may no longer be waterproof. Water may be entering through cracks, poor drainage, or defective flashing. Ignoring this can lead to rot, mold, and insulation damage.
What to Do:
- Inspect areas near windows, doors, and corners for leaks.
- Improve drainage around the foundation to direct water away.
- Call a masonry professional to reseal and repair vulnerable spots.
7. Pest Infestations
Insects and rodents can enter through gaps in the veneer. If ants, termites, or mice are getting in, the stonework may need sealing or repairs to block access.
What to Do:
- Inspect for small holes or cracks where pests enter.
- Seal openings with pest-resistant materials.
- For severe infestations, combine pest control with masonry repairs.
