Foundation repair

If you have walls that are cracked, floors that slope, doors that won't open or wooden floorboards that bounce back as you walk on them, your home may be sitting on uneven ground and require foundation repair.


Left unfixed, uneven or shifting ground may cause your walls to lean, creating cracks in the walls themselves and even the cornices and ceilings. Not only is this damage to your home unpleasant to look at, but as time passes it can become more difficult and more expensive to fix.


There are many reasons why the ground underneath your home may have become uneven –


  • Water may have flooded the ground, causing washout 

  • Change in moisture content allowing the ground to dry out and shrink

  • The ground could be re-active, expanding and contracting

  • Seismic activity or vibrations from nearby road may have shifted the soil

  • The ground may not have been well compacted in the first place


Whatever is causing the ground under your home to shift, foundation repair is a sure-fire way to stop further damage to your home and save money over the long-run.
