Home improvement projects can expose workers to asbestos, a toxic material commonly found in older buildings. It is important to inspect buildings constructed before 1970 for asbestos before starting renovation or demolition work, and to have any asbestos removed safely by trained professionals. Sump pumps installed by basement contractors can help resolve wet basement issues by pumping excess groundwater and moisture out of the basement through a pipe to the outside of the home. Sump pumps sit in a pit and are activated by a switch when water reaches a certain level. Along with sump pumps, additional waterproofing solutions like drainage systems may be needed depending on the specific basement moisture problems.
