Does your home have a wet crawl space? Have you ever had a crawl space inspection to find out if your crawl space or basement is currently waterproof?

If not, you'll want to get a crawl space inspection and get it waterproofed right away. Water leaking into your crawl space can lead to some serious headaches for homeowners, such as mold and air qualityissues. Fixing these problems can cost you thousands of dollars, so it's best to prevent them by waterproofing crawl spaces.

How Does Water Damage Crawl Spaces?

There are many different ways that water can seep its way into your basement or crawl space. This is especially true if you live in an area that is prone to a lot of rain, flooding, or humidity. The wet soil around your home's basement or crawl space will release excess water into the area. This can lead to crawl space mold, something no homeowner wants to deal with.

A lot of below-ground crawl spaces and basements are made of concrete or cement block, which might make you think that it's safe from water. However, these materials can actually be quite porous and water can still cause damage to crawl spaces.

If you notice certain signs like a musty smell, mold, peeling paint or stains, you might already have water damage and you should call a professional immediately.

Guide to Waterproofing Crawl Spaces

There are two main methods a professional will follow when waterproofing crawl spaces: interior waterproofing and exterior. Both methods have pros and cons, and which one you choose will largely depend on your home's unique qualities. Here is a breakdown of what the two methods entail:

1. Interior Waterproofing

Interior waterproofing starts from the inside and it destroys any moisture that enters your crawl space before it can cause serious problems. The type of barrier that you choose will depend on your home, but it can range from moisture barriers to sump pumps.

Many people prefer this method because you avoid having to dig up the yard around your home.

2. Exterior Waterproofing

Exterior waterproofing prevents any water from entering your home. It's typically more expensive, and requires excavation, or digging up the dirt around the foundation of your home.

After the outside of your basement or crawl space is exposed, layers of material are applied to your home. This method stops water at its source, and it works well for homeowners who don't want construction going on inside their home.

Which One is Right For Me?

There are pros and cons to both, but both options won't work for every home. Depending on the age of your home, exterior waterproofing might be the only option.

This is why it's crucial to meet with a professional for a consultation of your home. They'll be able to run tests and give you an expert on opinion on the best method for you.
