Visual Inspection – You can do a check yourself to determine where water may be entering the basement. If you are able to determine that the source of moisture is isolated to a particular spot, you may be able to avoid extensive repairs. Your problem can be as simple as excessive humidity which can be solved by a quality dehumidifier.
Gutter & Downspout Inspection – You should check to ensure that your gutters are free of debris and leaves and that water can flow freely off of the roof and away from the foundation of your home. Also check that the downspout is pointing away from the house and is directed to a spot that slopes away from the house. If the water is allowed to pool at or near the house.
Regrading – Regrading can work if too much earth has been allowed to pile up against the foundation of a cement block wall. Water can then potentially seep through wooden portions of your home. There should be at least 8″ of clearance between the ground and the top of the foundation wall. While this is something that may help, this is not a common cause for a wet basement.
If the above do it yourself techniques don’t help solve the problem then you will probably need to consult with a basement waterproofing professional. An expert can provide solutions that are more permanent and long lasting to help dry up your wet basement. A basement waterproofing contractor will provide some or all of the follow solutions:
Sump Pump Installation – A professionally installed sump pump will help pump water out of your basement.
French Drain Installation – A french drain can be installed either on the exterior of your home to prevent water from entering your basement or on the interior to divert water back out once it has already come in.
Vapor Barrier Installation – If your crawl space is retaining moisture a professional basement waterproofer can help install a vapor barrier to prevent that moisture from moving up in to your home.
The first steps in determining the best solution for your wet basement are to try and assess the situation yourself to see if there are any obvious fixes. If you can’t clearly see the problem for yourself or aren’t sure what the issue and solution are, you should contact an expert who can help you assess the proper solution to waterproof your basement or crawl space.
