Get matched with top excavation pros in Mitchellville, MD

"Very happy with my decision to hire this company to lay down sod and install a stone pathway in my backyard. They were professional and completed the work in a timely and thorough fashion. I would hire them again."

"7th state builders redid my kitchen floor and cabinets. The work was done beautifully."

"David and his crew did a fantastic job! They removed my above ground pool, pool deck, back filled in the dirt and completely cleaned up everything. Very professional crew. I was amazed by their efficiency. I would highly recommend hiring this company to do work. Very professional services."

"The work was done very well as discussed previously. Pablo was very conscientious with his work. Trees and bushes were trimmed to allow light for the grass. French drain to capture water runoff was installed. Work was done efficiently. Grass seed and cover were put down. Sump pump runout needs some more work as per photo."

"The whole project (installing a retaining wall) was seamlessly executed and I was completely satisfied. Because John K. took the time to carefully and patiently explain the various options and the details of how the project would unfold, I chose D&D (of course, the competitive price was also key). They took care of all the approvals with the HOA, began work on time as scheduled, and finished a day ahead of schedule,"

"First class all the way! Professional, highly competent and fair. Will recommend John to anyone I know. I had a well leak and a prior firm came out and gave me an outrageous quote for a solution that would not have addressed the problem. I reached out to Conex to do excavation to better assess the problem and not only did he get out quickly to do the excavation he was also able to diagnose and fix the issue at a lower cost."

When I had a follow up question, they came right back out to check the work, and went above and beyond to make sure my concerns were handled. I highly recommend your company. From our very first emergency call to the completion of the job, to the grass that is already growing to cover the big dig! Thank you for making a very difficult situation as calm and easy as possible. Jenn & Dave Peter, Columbia MD."
