"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

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in. 

If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.

Yes, a crawl space can add value to your home. However, there is a higher chance of it adding value if it is an enclosed crawl space, as this reduces issues caused by excess moisture in the home. That being said, a basement does add more value than a crawl space.

Venting the crawl space can be a good alternative to encapsulation if you live in a dry climate and the moisture problem isn’t severe. You could also try a dehumidifier or install a vapor barrier on the floor, leaving the walls exposed. A new drainage system may eliminate the moisture problem if it is not caused by humidity.

It is better to have a crawl space that is tailored to the outside temperature, your needs, and the season. For example, it is much better to have a vented space when it’s very hot outside and your AC bills are sky-high. Conversely, when the temperature drops and humidity rises, it is almost always better to have your vents shut and covered if possible.
