Hi, we are in the process of selling our home and during an inspection it was determined that there is water in the crawlspace. up to 3" and running alongside most of one wall. I would like to get a quote to repair this as soon as possible.

Wet carpet in basement. It might be caused by water seeping through the basement wall.

Split level home: - Uneven second flooring - Cracked concrete slap

My furnace gets its air exchange from the crawl space. My hardwood floors are cold and slightly damp. Corner exterior walls can get mold at the bottom under the beds. My wife smells mildew. My crawl gets water in the winter. I have one sump pump that handles most of it but there are a couple areas that get water because the ground's grade is less than perfect. Would like to solve the issues that cause the cold damp floors. House is 1K square feet.

Noticed several cracks in drywall in multiple areas of my home - Also, noticeable cracks in garage floor (concrete). This may be a foundation problem. Need your recommendation and estimate if confirmed this is a foundation issue.

We have a 4plex in Tacoma, it has a below grade basement and there is one crack in the concrete foundation wall, which allows water to seep in and flood the basement. Want advice on what is required to seal the crack in the concrete.

We currently have standing water in our crawlspace due to 1) a leaking pipe, and 2) undetermined cause...rain seeping in? Would like a bid -- we definitely need the water removed and probably a sump pump installed.
