Why Digging Out Your Crawl Space is a Bad Idea

We get asked all the time if we convert crawl spaces into basements and the short answer is no; Here's why.

First of all, the cost to convert a crawl space into a full and functioning basement is extremely high. The existing crawl space needs to be dug out, a new foundation poured and finishing on top of that. We are talking dollar signs.

We can take a closer look at the issues with adding on a basement and why that investment may not be worth it. Pouring a new foundation addition on a home is rather tricky. To gain access to pour the foundation the home would need to be supported on stilts while the new concrete is poured. This step is extremely important to make sure the seams are mended between the two seperate foundations so as to not allow leaks. Keep in mind basements are already suceptible to ground water intrustion.

Not only will this project cost you a lot of money but it will cost you a lot of time too. It is an extensive project with many steps that all need to be done correctly. With any type of extensive construction job, there is the risk of uncovering hidden issues that will delay the completion of the job and cause further interuption in your home and daily life.

We suggest taking a look at your motivation for converting your crawl space. If it is just extra storage space you are looking for, then installing a warranted 20mil vapor barrier is the perfect solution. Our CrawlSeal liner is sealed to the foundation walls to keep out moisture, dust and critters and provides the perfect place to store boxes, furniture, and all that unnecessary clutter, freeing up space in the rest of your home! Not only is CrawlSeal durable, warranted, and clean looking, but it is much more cost effective and installed in a day or less!
