"We paid close to $20,000 to BQ Basements to completely waterproof our basement. We still get water and they told us we need another sump pump installed at over $2,000. They guaranteed we would not get water after installation. Be aware they do not stand behind their work or honor warranties."

Basement Waterproofing questions, answered by experts

Flooded basement cleanup can take anywhere from a few days to several weeks, depending on the extent of water damage, the type of water involved, and the need for repairs or mold remediation. Severe cases with structural damage or extensive mold may require longer timelines. Quick action and professional help can speed up the process and reduce overall damage.

In some circumstances, foundation refacing or repair may be a better option for your home than sealing a foundation. It’s always a good idea to take steps to prevent moisture problems in your foundation, but if there are any structural concerns, those will usually need to be fixed first. When dealing with foundation issues, it’s a good idea to get a professional opinion so you can avoid bigger problems down the road. 

Yes, you can over dehumidify your house. While you may prefer a dryer climate inside, the elimination of too much moisture in the air can lead to an extremely dry environment that can affect those with respiratory and skin issues. Strike a balance between eliminating excess moisture without making your home feel like a desert. Most modern thermostats show the humidity levels for guidance.

It’s normally possible to stay in a house with water damage, but it depends on many factors. If the water damage is minor, like from a small plumbing or window leak, there’s minimal risk to you and your family members, especially if you catch it early. Major water damage from flooding is more likely to lead to mold growth and electrical issues, which means it’s safer to relocate until you have a professional dry out the area and treat the mold.

In nearly all cases, you are required to install a vapor barrier in your crawl space. However, local regulations will change based on the local climate and the crawl space's susceptibility to moisture. Even if a vapor barrier is not legally required, it is often a good idea to keep your crawl space dry.
