One way of basement waterproofing that many contractors will suggest for waterproofing a basement is to install a French drain system along the outside perimeter of your home.
To install an exterior French drain, the contractor will take the following steps:
You can expect the contractors to create huge heaps of excavated soil all around your home, creating a mess. On top of that, the process is extremely expensive, costing $15,000 to $20,000 per installation. The installation time is twice as long or more than if you choose to have an interior system put in.
French drain systems have been installed on the outside of homes since the 1920s, and if they were the best way to dry a basement, Mission Home Services would be installing them, too.
Unfortunately, placing a French drain or exterior footing drain along the outside is a recipe for failure. When you put a drainage system several feet under the earth, even in a bed of gravel, it will eventually clog with dirt, roots, and debris.
Sometimes, a contractor will try to stop this by laying down a layer of filter fabric around the drain. In this case, instead of the drain clogging, the filter fabric clogs and won’t let water into the pipe.
Other problems, such as freezing pipes and improperly sloped lines, are also common. This type of exterior drainage commonly will not handle water that collects under your basement floor, in which case you’ll still need a sump pump inside your basement.
Some contractors even connect the exterior drains to the sump pump inside. Now that’s sure to clog! And what happens when your drainage system clogs? It will need to be excavated and you’ll have to start over. Who wants to do that again?

“Dave was super responsive and went above and beyond in getting my basement project completed. He kept in regular contact with me on updates to the project, expected delivery of materials, and on permitting status. Very reliable and did a terrific job on my basement retaining wall.”
“First of all, I don’t usually do reviews; however, I was so impressed with the guys at Mission Home Services that I felt the need to let others know. We had them out to inspect our basement and give us an estimate on waterproofing it for future renovations. The representatives gave us a great education on not only how a basement leaks, but also how ours was leaking and the correct method to fix it. We highly recommend this company!”
