Buy A Dehumidifier

We advise you to buy a dehumidifier in addition to waterproofing the surface. If you want to reduce humidity in your basement and prevent condensation and mold from spreading. Choose a dehumidifier plugged in so that it automatically drains off the humidity as soon as it becomes too high.

Choose Waterproof Carpeting Materials

If your basement is humid, it is bound to get moldy. If you have made wet basement remediation, it is advisable to use carpeting that does not absorb moisture. Put a waterproof carpet on the floor to create a buffer between the basement and the carpeting.

Apply Waterproof Sealant To Walls And Floor

Keep Wood Surfaces And Water Separate

If the basement walls have been in contact with water for a long time, dry rot can appear on the floorboards and support beams. The original source must be eliminated to prevent it from spreading across the surface. Locate all wood shelves away from pipes and floors so that items with condensation do not come into contact with it.

Look For Outdoor Issues

The spread of mold and rot on basement walls is often caused by leaking pipes under the house foundation. So before you start the works, you should check if the pipes are in good condition.
