Costs for repairing a wet, leaky basement begin around $15 or $20. This will cover the cost of gutter extensions, splash guards and leaf covers. All are fairly easy to install and should take no more than a few hours to do so.
Medium repair work, such as fixing a hairline crack (Image 1), will cost around $50 and take about half a day to complete.
Serious structural damage to the foundation (Image 2), which can run more than a thousand dollars, should always be done by a professional. If structural damage is found, get several estimates before beginning any work.
Take preventive measures such as applying cement paint; a stiff brush will be needed to apply the paint to cinderblocks. Dip the brush in the paint and apply generously to the cinderblocks.
A stronger preventive measure, cement coating, will actually create a chemical reaction that will bond with the wall. Mix up the cement coating with water until smooth and apply with a very strong brush directly onto cinderblocks.
A condensate pump can be installed to the dehumidifier's hose connection so that instead of going into the bucket, the water will drain into the condensate pump. Hook up a hose to the condensate pump's drain line to pump the unwanted water up out of the basement.
