With a perfect rating of 5 stars from 46 reviews, Crawlspace Commandos is highly regarded for its thorough waterproofing services. Customers appreciate their professionalism and efficiency, making them an ideal choice for homeowners facing serious moisture issues.

Dryspace Crawlspace Solutions also carries a 5-star rating, albeit from 36 reviews. Their clients praise their attention to detail and customer service. This makes them a strong contender for those seeking reliable waterproofing options. Still, the lower review count compared to the top pick may raise some questions about consistency.
Crawl Space Brothers holds a solid rating of 4.8 stars from 25 reviews. Customers appreciate their friendly approach and effective solutions. They are a good fit for those who want a personable service. However, with fewer reviews, their reputation is still in the process of solidifying. The review base is still thin, so we read the rating as promising rather than proven and weighted it accordingly. Most of what reviewers hire it for is personable service. It serves Columbia, SC, with $100 to $300 pricing, and the honest trade-offs are fewer reviews and slightly lower rating.
