The most important thing you need to check for here is proper licensing. To work as a contractor that lays down foundations, a contractor needs to be licensed. As you can imagine, foundation work is often highly regulated. This is because it is one of the most important factors in the stability of your building. Without a strong foundation, a building can become lopsided with time and even become completely structurally unsound. You need to only work with licensed foundation layers.

You also need to make sure that your contractor is insured properly. During the process of laying down a foundation, a number of things can potentially go wrong. Many of these things are completely out of the control of the contractor. If something goes wrong and you need to hire another contractor to fix it, then you could be stuck with that financial burden. Hiring a contractor with insurance will ensure that you won't be stuck with those extra costs if something bad happens.

Always get an estimate before you let the contractor start working on your property. You may have to walk the contractor around your property to let him or her get a better idea of what needs to be done.
