"Most of the employees were conscientious Work lasted about a week and was the installation of a waterproofing system in my interior basement. The cement over the drain is very uneven with the existing flooring in much of the area. No way could carpet be used after this. Anyone contemplating this same kind of work should specify floor must be level and ask to see actual material covering the walls, not just pictures to avoid surprises. Clearly much of my disappointment would have been avoided if I had been more fastidious in my specifications and investigations."

"Austin was extremely professional and did very nice work. We had grading issues near the house and Austin helped craft a solution with me and then made it happen. I had struggled with other contractors in the area returning calls, not showing up when they said they would, and a variety of other issues - I did not have any of those issues with Clear View Land Management LLC. They showed up when they said they would, did what they said they were going to, and the price was very reasonable. I've included a few before photos of our issue, and then after the grading, and then after they were finished."

"The work Everdry performed was excellent and The team was very professional and helpful through the whole process. Even today they are just a phone call away with any questions or anything I have about the work they perfomed in 2021. Along with that I haven't seen a leak or anything the basement drier than it has ever been and I couldn't thank them enough for all they did. 10/10 would recommend to anyone who needs their basement waterproof or looked at."

"The weather interfered the day they were first to come and utilities didn’t measur and m ark in a timely matter but Rion came on time left when they said they would. They were clean and cleaned up and the workers were nice and considerate, especially with my neighbors I was concerned about hiring a basement waterproofer but I would recommend them without reservation. I love my egress window. What a difference it makes."

Basement Waterproofing questions, answered by experts

Unfortunately, mold can grow pretty much anywhere, on any kind of surface. However, you’re most likely to see it in damp areas like basements or bathrooms, as well as anywhere there has been a water leak. Consult a local mold specialist to determine if certain areas of your home are prone to mold based on climate and other factors.

Water damage to concrete is often gradual and can take months, if not years, for a concrete structure to be fully destroyed. The process often starts with cracks on the surface, followed by sinking slabs and eventually crumbling cement. Therefore, it is important to repair minor damages early to prevent the situation from worsening.

You’ll need to reseal the foundation every five to 10 years, depending on the sealant you’ve used, the moisture conditions present in and around your home, and the condition of your foundation. Having a foundation inspection conducted before reapplication can help you catch any problems before you begin resealing. Of course, if you notice any new leaks or other moisture problems at any time, it may be necessary to reseal the foundation sooner.

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.

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.
