We do not recommend that you try to waterproof your property’s crawl space alone.
Damage and Drama
DIY repairs can seem attractive, but there are a number of things that can lead to this process being far more costly (in both time and cash) than a professional service would have been. However, before the process of waterproofing can even begin, you must consider the state of your home. The source of crawl space water must be determined and repaired before waterproofing or the consequences could be truly dire.
If you are not capable and confident in your ability to diagnose and deal with the structural issues that may be causing the flooding as well as all potential co-occurring issues, it is best to leave waterproofing to the professionals. You may find that foundation settlement and spreading cracks are the source of the moisture, in which case serious structural repairs will be needed.
Professionals Do It Better
There is a real risk of causing more damage or even causing injury to yourself for anyone helping you when it comes to dealing with crawl space water effectively and definitively. Whether this happens during structural repairs or the waterproofing process itself is irrelevant—one wrong move can cost you a lot. As such, it is really best to let the professionals handle any waterproofing process.
After all, they have access to all the best tools and products, some of which you may not be able to get ahold of in a regular hardware store. Working with sub-par products will pretty much ensure a lower standard of result, but that doesn’t even begin to account for the cost of hiring specialist tools if you need to undertake foundation repairs. Professional services offer a better result, often at a similar or lower price, than DIY work.
