"They completed it in 2 days and I havent had an issue since the basement was waterproofed. However, they did forget to plan the initial inspection prior to the work as part of the permit. The city I live in ended up reaching out near the end of the permit date and I didnt know about it until then. I reached out to the project manager for my project at Acculevel about it and they did handle that issue promptly."

Basement Leak Repair questions, answered by experts

Although waterproofing your basement may not directly increase the value of your home, it will protect the value you already have by preventing water damage. A basement without any signs of water will be more appealing to prospective home buyers. A leaky basement is a major red flag during a home inspection, and it will likely reduce the amount that buyers are willing to pay.

The best way to fix dampness in walls is to find the root cause and fix the underlying issue. After that, you’ll need to dry the wall with a heavy-duty fan and potentially a dehumidifier. If the wall has water damage, you can remove the damaged drywall, patch it with a new piece, and then paint it to match the rest of the wall. 

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. 

French drains may fail when they become clogged with soil granules that slip through the pores of the landscaping fabric and through the holes in the pipe. 

Over time, this debris can build up inside the pipe and prevent water flow. To prevent this failure from happening, regularly flush out your French drain and keep debris away from the inlet grate.

The need for permits in drainage improvement projects depends on your location and the extent of the project. Generally, projects involving significant excavation, alterations to existing drainage systems, or those impacting public drainage systems may require permits. Check with your local building department or authorities to determine the specific permit requirements in your area before starting any drainage improvement work to ensure compliance with local regulations.
