A home may look flawless after renovation, but without proper drainage and waterproofing, hidden water damage can undo all the work. Water is one of the most destructive forces in a building, leading to mold, rot, and structural instability.
Common mistakes include failing to slope landscaping away from the foundation, skipping waterproof membranes in bathrooms, or ignoring basement sealing. Even small leaks around windows, roofs, or pipes can quietly cause thousands in repairs.
Good waterproofing starts before finishes go in. This means installing drainage systems, vapor barriers, and high-quality sealants in vulnerable areas. Roof flashing, sump pumps, and gutter systems also play key roles in keeping water away from living spaces.
The extra cost of waterproofing may feel unnecessary during construction, but it protects your renovation from being ruined by the first heavy rain.
In short, neglecting drainage and waterproofing is like building on sand. Protecting against water ensures your renovation stands strong and healthy for decades.
