Basement Waterproofing questions, answered by experts

Mold and mildew are always a primary risk with any water damage, but it’s not guaranteed that mold will grow. The chances of mold growth are dependent on many factors, such as the severity of the damage and how quickly the area was cleaned up and dried out—that’s why responding to water damage immediately is imperative. If you suspect you have mold and mildew growth, you should talk to a local mold removal expert .

Your homeowners insurance can cover slab leak repairs, but it really depends on your policy. Some homeowners insurance policies only cover slab leaks caused by natural disasters, while other plans are more comprehensive. You might also want to check your home warranty plan to see if they'll cover the cost of the repairs if one of your appliances caused the leak.

Preventative measures, such as maintaining drainage systems, installing sump pumps, inspecting roofs regularly, and crafting comprehensive emergency plans, can help mitigate future risks.

Alternatives to gutter systems include rain chains and drip edges, which work to disperse rain coming off of your roof to a wider section of the ground to prevent erosion and pooling. These options aren’t standalone alternatives to gutters in all parts of the country because they don’t divert water. They’re often reserved for dry climates. On the ground, you can also opt for a drip path or French drain. These can serve as standalone alternatives, but they’re expensive and can detract from your curb appeal and usable yard.

Most houses will have vents in the crawl space. This allows for air passage and energy retention, which in many ways can help control the temperature inside the home. If you are able to consider the cost of a crawl space encapsulation, you may not need your crawl space vents at all.
