A basement sealer is vital to keeping the contents of your home, and its foundation, from suffering the effects of leaks. Many solutions for sealing basement walls and floors are do-it-yourself, although a few may require the help of a professional.

In order to stop a leak from causing further problems, it is necessary to first identify the leak. Once the origin is determined, then it will be possible to choose the proper sealant for the problem. Cracks in the walls and floors can be patched with cement or epoxy sealers and a putty knife.

If there are not any immediate problems with the walls or floors, prevent future damage by applying one or two coats of basement sealer.

It is also important to safeguard the basement by ensuring that water can't make its way into the home via the foundation. Be sure downspouts are pointing away from the base of the home, and clear gutters of debris to allow for proper drainage. Other options include digging a trench to keep water away from the foundation or installing a French drain.
