Common Warning Signs of Foundation Problems

Warning Signs of Foundation Problems - Wall Cracks

1. Wall Cracks

Wall cracks are one of the most visible indicators of foundation problems.

  • Types: Horizontal, vertical, and stair-step cracks.
  • Causes: Foundation settling, soil movement, or excessive moisture.
  • What to Watch For: Cracks wider than 1/8 inch, recurring cracks, or those accompanied by bowing walls.
  • Action Needed: Professional evaluation to determine if structural repairs are necessary.

2. Uneven or Sloping Floors

Uneven floors can indicate shifts or settling in the foundation.

  • Causes: Soil erosion, poor drainage, or improper soil compaction.
  • What to Watch For: Noticeable slopes, gaps between the floor and baseboards, or creaking sounds when walking.
  • Action Needed: Foundation leveling or underpinning to stabilize the structure.

3. Sticky Doors and Windows

Doors and windows that are difficult to open or close can signal foundation movement.

  • Causes: Shifting foundation, humidity changes, or framing distortions.
  • What to Watch For: Gaps around frames, misaligned doors, or windows that stick.
  • Action Needed: Repairing the foundation to restore alignment.

Signs of Foundation Failure - Gaps Around Windows, Doors, or Walls

4. Gaps Around Windows, Doors, or Walls

Gaps can form as the foundation shifts or settles unevenly.

  • Causes: Soil shrinkage, foundation settling, or water damage.
  • What to Watch For: Spaces between walls and ceilings, gaps in door frames, or separation around window sills.
  • Action Needed: Address the root cause of foundation movement and seal the gaps to prevent further damage.

5. Bowing or Leaning Walls

Bowing walls are a serious sign of structural stress.

  • Causes: Hydrostatic pressure from water buildup, expansive soils, or poor construction.
  • What to Watch For: Walls that bulge inward or outward, horizontal cracks, or noticeable lean.
  • Action Needed: Reinforcing walls with steel braces, carbon fiber strips, or wall anchors.

Signs of Foundation Problems and Failure - Basement Water Leaks

6. Basement Water Intrusion

Water seepage in the basement can indicate cracks or structural issues in the foundation.

  • Causes: Poor drainage, hydrostatic pressure, or foundation cracks.
  • What to Watch For: Standing water, damp walls, or musty odors.
  • Action Needed: Waterproofing the basement and repairing foundation cracks to keep water out.

Why Address Foundation Problems Early?

Ignoring foundation problems can lead to:

  • Structural Damage: Small issues can escalate, leading to long term effects from untreated foundation cracks and compromising the stability of your home.
  • Water Damage: Cracks and gaps allow moisture to seep in, causing mold growth and wood rot.
  • Pest Infestations: Openings in the foundation provide entry points for pests.
  • Decreased Property Value: Foundation problems can deter buyers and reduce the resale value of your home.

Dale and the guys did a fantastic job. We had a significant wall lean, and they made the repair look easy. They walked us through the permit and inspection processes. Their work is quality, and they are easy to work with. Highly recommended.

My experience with Cornerstone was a few years ago. I had a sump pump completely replaced, an entire basement wall braced and an outside (garage) wall piered. I have not had a problem since the work was done. The workers and the owner, Dale, were at my home when they said they would be. I am pleased with the work that was done and found Dale to be a man of his word. I would not hesitate to recommend Cornerstone.

We were getting ready to close on our house and 1 week before closing a heavy rain came and we had water in our laundry room in the basement. Dale and his crew came out the next day and got started on fixing the issue. They were fantastic and very detailed in explaining what they were going to do. Had it done in their time frame and cleaned everything up. Very professional and excellent service.

Quality work from quality folks. I called on a Friday afternoon to get a quote for poly jacking our sidewalk. They came out on a Saturday morning to take a look and got us on their schedule. Quite happy with how the fix looks as well!

After the huge flood, we had July 26, 2022. I finally decided I’d had enough with the flooding issue and contracted Cornerstone Structural Repair & Waterproofing to knock out my sliding glass door in my basement and cement the opening to form a solid concrete barrier. I am very satisfied with the end results!! Dale and his workers did a great job, very respectful of the property, very friendly and professional, and cleaned up after the work was completed. It has already come in handy after 27 years of dealing with flooding in my basement and replacing numerous appliances. I can be at peace now not having to worry every time we have a torrential downpour. Please see attached photos of the 2022 flood and the flood event this year in April. Kudos to Dale and his team!!!! 😁
