Jim frequently gets questions from homeowners when they start to notice cracks in their concrete. He says there is no need to worry about small cracks. All concrete cracks by nature – that’s why we put reinforcement in it – to hold it together and control the cracks.
What to be on the look out for:
· If the cracks are large enough to slip 2 quarters in
· If they start to stair-step – one side rising higher than the other
Once either of these occurs it may be time to get someone out to evaluate the foundation and determine the cause of the movement.
As for those hairline cracks – sleep well they are nothing to worry about.
