"They had to take out a portion of my front wall which was not planned on, and the conic quality of the concrete was not as good as I thought it should be they destroyed the brick wall that they said they would be able to save and I think they also damaged an additional plumbing line, which I’m going to have to have repaired But we did get the leaking stopped, which was the big part of the problem they had to dig up the entire front foundation down to the 8 foot footer and re-waterproof the wall put in a French drain system and a new drainage system for the gutter and a sump pump"

Basement Waterproofing questions, answered by experts

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.

Some disadvantages of crawl spaces are mostly regarding the air itself—moisture build-up and poor ventilation, which can cause problems both in the house and underneath it, even damaging the foundation itself. Crawl spaces are difficult to access and often invite unwanted pests during the hot summer months and the cold winter ones. These hard-to-seal spaces are also susceptible to water damage during periods of heavy rain or melting snow.

Encapsulation can take the place of crawl space vents since it protects the area from moisture and air all year round. Determining whether you should open or close crawl space vents can be complicated since it often depends on the weather and humidity. Skip this step by investing in crawl space encapsulation whenever possible.

Water damage always poses the risk of mold, but if you act quickly enough (within the first 24 hours), you may be able to avoid mold growth resulting from water damage. Clean up the water quickly and thoroughly dry the area. If the issue is more extensive or you didn’t act quickly enough, it’s always safer to assume mold has grown and hire a mold inspector to examine the area.

If you set up a dehumidifier, it will usually dry out your wet crawl space within 12 to 24 hours. Once the space is dry, it’s a good idea to take preventative measures to keep it dry. These include installing a French drain or other exterior foundation drainage system, installing a sump pump in the crawl space, and installing a vapor barrier in addition to leaving the dehumidifier running.
