Why your basement floor needs sealing

Concrete is porous. Water vapor moves through it from the ground below. Without a sealer, that moisture comes up through the slab and into whatever sits on top of it, whether that is flooring, drywall, or stored goods.

A sealed basement floor does several things at once. It blocks moisture from migrating up. It makes the floor easier to clean. It gives a finished surface that does not chalk or dust like raw concrete. And it gives you a real option for living in the space instead of treating it as a utility room.

For homeowners finishing a basement, sealing is not optional. Drop carpet or flooring over an unsealed slab and the moisture below has nowhere to go. Six months later you have a problem you cannot see until something starts smelling musty.

For finished basements that have not been sealed yet, it is not too late. We grind off whatever has been done before and apply the right product for the slab.
