In 2023 I decided to consider purchasing a property and building that home we all dream of. Of course being my first time out I made sure to have it contingent on a survey and having a perc test performed. The survey company recommended Soils Inc. With a 60 day window looming I contacted Carla Adgate who explained the process, pricing and then coordinated with her team to ensure the site was able to perc within the timeframe to go to closing. Janelle Salapich arrived with her team and walked the 40 plus acre property to perform dig sites in two separate areas.
The turnaround was less than a week for formal reports. Recently I had to reach back on some separate testing. Also the builder wants to move the drain field on the build site. Although they had a skeleton crew working, Vicki Kapral was onboard and quickly got me in touch with Carla. Ultimately Carla and owner Mark Smith not only moved up the timeline to accommodate the county, but Mark discounted their fee!
It is wonderful to have a company that is on the cutting edge of technology and yet still has old fashioned business values. Would I use them again? You know the answer, ,,,a nd you should as well! Laura Duvall

Mark and his team are truly outstanding! They possess an exceptional depth of knowledge about septic systems and provide very fair pricing. After reaching out to numerous companies in the area, Mark's stood out as the clear choice. His extensive experience with the health department is evident in the quality of service they deliver. Communication has been seamless; they are consistently responsive to emails and easy to get in touch with.
I highly recommend Mark and his team for anyone needing septic system services! They made what was an extremely stressful situation very easy! Thank you so so so much Mark and Soils Inc.! their sister company Virginia Septic is absolutely amazing. Rick, the owner, he has literally answered all my emails and calls so thoroughly and even came all the way to the property for an extra visit to help the electrician with the work! I could not recommend soils inc and virginia septic more!

From start to finish, Soils, Inc., provided the utmost level of professional and courteous service to my company for a very complicated subdivision projected in Fredericksburg, VA. Their soil scientists and soil technicians all kept me abreast about the entire process, fees, forms, timeline, and met with me at the job site and explained the entire soil investigation and septic design process in great details. I will be working with this company going forward for all of my new home construction designs and subdivisions where septic systems and soil investigations are required.
