Many of us with older homes or unfinished basements still need to maintain a clean and practical flooring finish. Keeping the dust down from an unfinished floor can cause needless effort. The best solution, would be to cover the floor with an epoxy finish. Prepare the surface by filling all the cracks and ensuring the area is as level as possible by using self-leveling floor compound. Make sure the floor is good and dry before application of a two part epoxy paint which can be rolled on. Plan to do this at a time in the year when good ventilation will help dry the paint. If this is too job for the home owner, then give a contractor a call.

Mold 

As everyone knows, your home is your largest investment and sustains equity of properly maintained.  There is no other better way to conserve your property than to rely on professional and knowledgeable trades to make timely repairs to avoid costly long term problems.  The most common and unsightly kind of repair involves mold caused by damp.  Don't make the mistake of doing a cosmetic patch job with plaster and coats of paint, only to discover that you'll have to repeat the same job over and over again.  First of all, discover the source of the water damage, whether it is a leaky roof, improperly installed and serviced gutters, or a burst pipe.  Call in the repair people to assess the damage.  We have several trades to recommend.  Secondly, if this is a basement problem, there might be inadequate ventilation and during rainy, muggy summers, a dehumidifier is a must.  Lastly, call in a contractor who will thoroughly remove all rotted wood, soft plaster and drywall, replace with clean new materials and seal the area with the appropriate paint materials.
