Interior vs. Exterior Waterproofing

Owning a home is a big accomplishment! It is understandable that as a homeowner you want your house to be in the absolute best condition possible. You can achieve this great condition by keeping up with maintenance tasks and properly caring for your home. One specific way that you can prevent your house from being damaged from weather conditions is by waterproofing your basement. If you want more information regarding basement waterproofing, here is a detailed look at interior vs. exterior waterproofing of your basement.

Exterior Waterproofing

This is your home’s first defense against all things nature. Gutters, exterior drain systems, downspouts, and drain tiles are all examples of exterior waterproofing options. In one way or another, all these items are designed to collect water and move it away from your home. There is one more exterior waterproofing option that is done to houses when the foundation is installed. This is known as a waterproof membrane and it is designed to seal out moisture so that the concrete doesn’t absorb it. If the concrete absorbs it, it can crack and eventually allow water leaks.

Exterior Waterproofing Cost

Installing these different exterior waterproofing options can cost more than interior waterproofing, but that is because it requires more work and more materials to keep your home dry. Thinking reasonably about the price will lead you to the underlying factor of how much money you will save from not having to deal with water damage. Isn’t that nice?

Interior Waterproofing

There are a few different interior waterproofing options, one of them being the interior drainage system. This system is made up of pipes and drains that are under the foundation to catch any leaks or excess groundwater and remove it by using the sump pump. Another common option is vapor barriers which are designed to seal out moisture by using plastic or foil sheets along the walls of your basement. Lastly, it is important to always make sure that cracks in your foundation or in your window wells are dealt with as soon as you identify them. Getting ahead of the situation is always the best option.

Interior Waterproofing Cost

Waterproofing a basement can cost between $7,000 to $11,000 and that includes a vapor barrier, drain tile system, sump pump, and a backup. Waterproofing a crawl space can cost between $4,000 to $7,000, also including encapsulation, drain tile, sump pump, and a backup. Keep in mind these are ballpark figures based on the average single-family home. If the projects are more complicated, the prices may extend past these estimates.
