Unfortunately, many homeowners make expensive mistakes during the process, believing a simple patch or layer of sealant will solve the problem. Be it Columbia or any place with heavy rains and storms, steering clear of typical errors can save thousands.

So, what are the most common mistakes—and how can you avoid them?

Key Takeaways
? Ignoring exterior drainage can lead to disaster.
? Waterproof paint isn’t a permanent solution.

? Baseboard or perimeter channels
? Pump systems with backup support

Mistake #4: DIY Waterproofing Without Research

DIY methods can create bigger problems. Common missteps include:

? Pumps

Mistake #10: Addressing Only Interior or Exterior
