Hired Crawl Space Ninja without any back knowledge, and that can backfire, but NOT SO with this company. Jordan arrived, surveyed a difficult job with professionalism and great attitude. 2 weeks later, Project Manager Max, Tom, Tony & Andrew showed up ready to work. 3 days of hard work in a tiny crawl space. They not only did the work, but did so with a hard working, good attitude, and explained all they did. The job was completed on time and all seems to working as planned and very pleased with results. BUT mostly pleased with something that is EXTREMELY RARE these days...Great Customer Service With A Great Crew With A GOOD ATTITUDE! It cost a lot, but worth every penny for the rarity of good attitudes...and I'll always pay more for that! Says a lot about the company and it's leadership.

Working with Crawl Space Ninja we were able to identify the issues with our crawl space and make a plan to address the problems . Mike and Jordan were courteous, respectful and professional. They have been responsive and honest.
We recommend them to any owner needing assistance with their home crawl space.

This review is long overdue - mea culpa to the team at CSN Alpharetta. 2 years ago I had my crawl space encapsulated by Crawl Space Ninja and could not be happier with that decision. My home is noticeably drier, smells cleaner, fixed the moisture issues, and as a side note unlocked a ton of storage space. In my case the encapsulation has paid for itself: I had a hot water heater leak into the crawl space that was caught early because I noticed the faint hum of the dehumidifier running constantly. I could clearly see puddles of water at the low points and some wet subfloor which was an easy fix to dry (encapsulation helped a ton here). Prior to encapsulation this likely would have gone on for weeks until it seeped through my hardwood floors in the living room and the entire subfloor.

What really sets this company apart is that crawl spaces are their bread and butter and not some thing they do on the side like foundation and pest control companies. Their website and youtube channel is filled with invaluable information - what you see is what you get, and they sell all the same products for diy encapsulation. This is not a cheap project by any stretch, but the price was exactly as their CEO estimated in one of his youtube videos. There are a lot of companies (*cough* aquaguard) charging a lot more ($5k-$10k more) for an inferior product; no other company soda-blasts your joists and subfloor, which is much more effective than chemical treatment. CSN will work with you at any budget, prioritizing what is most important in your space (poly barrier and dewatering) and adding the rest later, or doing a hybrid diy-contractor approach to fit your budget.
