We just had an unbelievable amount of rain and now the calls are coming in. Help, my basement is flooding.
In the last week I have been to Rockville, Gaithersburg and Leesburg, VA to evaluate and trouble shoot water problems and mold.
Most basement water events are related to water pressure directly around the building. When the ground can’t hold any more water then basement dampness can happen to anyone and there is not much that can be done short of a french drain and sump pump (cost $6000-8000).
The Answer Is Usually Inexpensive
Fortunately complete soil saturation events are not so common. Nine times out of ten water that gets into the basement used to be on the roof.
Most people with basement water problems can improve their chances significantly by doing the following 3 things:
1) Clean your gutters- Every home I have visited recently with a water problem has had clogged gutters and every owner said they were clean.
2) Extend your downspouts- We recommend extending downspouts away from the house at least 6 feet to insure water runs out of the back fill area and onto dense soil.
3) Have a positive grade near the house- Almost every home we inspect needs some measure of grade improvement near the foundation. We recommend a 1 inch per foot grade slope away from the house extending out at least 6 feet using a heavy clay type soil. Cost to regrade an entire house is usually less than $1000.
While we can never guarantee a dry basement, do these three inexpensive steps and water problems are likely to become a thing of the past.
