"Bill and his crew exceeded our expectations. Both our water damaged basement and our failing garage foundation required a change in course and they communicated options and provided excellent and economic solutions. They arrived early and stayed late 6 days a week to work around our weather. They provided extras as we went along and worked through some tough weather conditions. The daily communication was the best. Their prices saved us so much money. Their clean-up left our place in better condition than when they arrived. This company is going places. We will use them for any future needs."

"Kurt is a great guy to work with. He did what he said he would, did it on time, and the work was high quality. He provided me with references who all had good things to say about him. He let me know exactly what he was going to do before hand, got it done as promised and clean up was great . I would recommend Owl Creek Enterprises to anyone."

Foundation Repair FAQs, answered by experts

The best solution to fix a foundation crack in your basement floor depends on the underlying cause. If you just have hairline cracks from settlements that are no longer growing, the best option is to seal them with a crack sealant. If the cracks continue to grow, one edge rises above the other, or there are signs that water is getting in through the crack, a professional repair will be necessary. Depending on the root cause, your professional may employ foundation underpinning or some other type of stabilization, seal the cracks, or install a drainage system.

You can use a level or straight-edge to test for plumb foundation walls and a level slab, a level or a ball to check for sloping floors inside your home, and a hygrometer to look for moisture in your underhome area. Aside from these DIY tests, it’s important to get a foundation repair specialist or structural engineer to test the foundation to see if it’s supporting your structure properly. They can determine if the loads on the concrete are uneven or need reinforcement.

While it can be difficult to identify a bad foundation at first glance, look for large horizontal cracks, discoloration, bulging basement walls, or signs of water damage. You may also see large gaps between the home and the foundation on the outside or signs of pooling water from a recent storm.

Addressing gaps and cracks reduces heat loss and improves energy use.

Although some concrete cracks are cosmetic, others can be more serious. Cracks wider than ⅛ inch or that extend through the slab are serious and can cause structural damage. If you notice these types of cracks in your concrete patio, contact a local contractor who installs concrete patios to inspect the damage and determine how to fix it.
