Problems that begin in the crawl space affect the entire home
Crawl space homes are much more common in the south and west coast, but can be found just about anywhere. Since crawl spaces are left exposed to the elements, they are naturally susceptible to foundation damage.
When it comes to crawl spaces, there are 3 areas of concern:
Crawl spaces can become a mess – wood rot, pooling water, uneven floors, foul odors and mold are just a few examples of the problems that can affect an untreated crawl space.
Fixing crawl space problems is easy with Olshan
At Olshan, we carefully investigate the problems affecting your crawl space to determine the best solution. By carefully analyzing your home and soil, we are able to not only fix the symptoms (like cracks or sagging floors), but also treat the source of the problem to ensure a long-lasting solution.
What happens if my crawl space is too low to the ground?
Small spaces are no problem for Olshan. We understand that some pier and beam crawl space homes can be very low to the ground. Sometimes under 1.5 feet. Most foundation pros are unable to navigate these tight, dark spaces.
At Olshan, we use robot crawlers designed to navigate the tough terrain under your home. These gadgets deliver real-time 4K video and are able to help us identify structural problems as well as assess issues with moisture, mold and mildew.
