"Basement Improvements waterproofed my basement and poured a new concrete floor. Both my basement steps were ruined by Basement Improvements, LLC. I have steps from my garage to the basement that they removed and destroyed. They also ruined the step from my house to the basement by cutting the steps instead of putting the concrete around the step. They cut the steps 2" high. They also buried the lines from my oil tank and heater in concrete. I filed a complaint with the BBB and expect to be reimbursed. The communication was incredibly poor throughout the entire process. I did not know my steps would be cut or that my lines from to the oil tank and heater would be buried in concrete. Nothing about the process was communicated to me until I asked a series of process questions. My questions about the process were treated as a burden. It was never communicated to me that my steps would be cut. It was never communicated to me that my connections would be buried under concrete. It is never communicated to me that my steps up to the garage would be damaged. I regret using Basement Improvements and wish I had chosen a more professional and responsible business. I regret not choosing TC Hafford. I choose Basement Improvements because the cost was lower, but with all the poor workmanship, my cost is higher. Don’t make the same mistake I made, choose a professional company to do this work."

Basement Waterproofing questions, answered by experts

Homeowners insurance may cover basement flooding, but only if a covered peril causes it. For example, a burst pipe may be covered if the event was sudden and accidental, not caused by wear and tear or homeowner neglect. Flooding caused by extreme weather is only covered if you have a separate flood insurance policy.

While water in your basement is unlikely to make you sick unless it’s coming from a sewage backup, mold is likely to start to grow in wet areas within 24 hours, and mold can make you sick. According to the Centers for Disease Control and Prevention (CDC), inhaling mold spores can cause allergy symptoms, including runny nose, itchy eyes, difficulty breathing, wheezing, and itchy skin. Individuals with pre-existing respiratory issues like asthma and immunocompromised individuals are at an elevated risk of symptoms when inhaling mold spores.

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.

Interlocking garage tiles made with PVC are the most effective for garages with past issues of humidity and flooding because damp concrete is not suitable for paint. Epoxy coating is also water-resistant and can prevent mold buildup. Finally, porcelain tiles are a wonderful option for wet conditions if your budget allows.

One handy thing about whole-house dehumidifiers is, once installed, you don’t have to worry about placement or changing the dehumidifier’s position. But if you are using a portable dehumidifier, we suggest keeping it away from walls, vents, and furniture. It needs a central, unobstructed spot with access to lots of air to do its job.
