Everything You Need To Know About Wall Waterproofing


When it comes to waterproofing, walls are often the forgotten surface. People tend to think about waterproofing in terms of keeping water out of a building, but what about when water already exists on the inside? Damaged and wet walls can lead to a host of problems for homeowners, from mold growth to structural damage. This blog post will discuss everything you need to know about wall waterproofing!

What It Entails

Wall waterproofing is a process of protecting your walls from moisture penetration. It can involve both interior and exterior waterproofing, depending on the location of the wall and where the water is coming from. Interior waterproofing usually involves removing any existing layers of drywall or plaster, inspecting for structural damage, applying a primer/sealer, installing a waterproof membrane over the entire wall area, and then applying new drywall or plaster to complete the job. Exterior wall waterproofing can be more straightforward; it typically just involves covering the outside with a thicker protective membrane.


The primary benefit of wall waterproofing is that it prevents future issues such as mold growth and structural damage due to moisture inside your home. Additionally, waterproofing can help you save money in the long run by preventing costly repairs and replacements. Finally, it can also give your home a more finished look since you won’t have to worry about water staining or other issues caused by moisture on your walls.

How Much Does Wall Waterproofing Cost?

The cost of wall waterproofing will vary depending on the size and scope of the project. On average, most homeowners should expect to pay between $1,200 and $3,000 for interior waterproofing jobs and between $2,500 and $8,000 for exterior projects. The final cost could be higher or lower depending on the materials used and local labor rates.

Wall waterproofing is a crucial step to take when protecting your home and extending its life. It can protect against water damage and reduce energy costs and enhance the overall look of your home.
