“When I need bids for projects, I trust Concrete Jack to give me a fair price. From the initial call, they make you a priority up to the finishing of the job. Tom, who I’ve dealt with the past few projects, has been very professional and even if I need a quote quickly, he always comes through.”

Tammy Powell, SMG Properties

“On behalf of the property management team at Buchanan Properties, I would like to extend our thanks and appreciation for a job well done. The work was completed before the budget year-end despite the challenges of working around cold, ice and snow. We received zero tenant complaints, which is remarkable given that Concrete Jack was working in vehicle and pedestrian high traffic areas. We look forward to the opportunity to work with you again at some time in the future.”

Kevin Burns, Buchanan Partners, LLC

“The employees work efficiently to ensure the job was completed to our satisfaction and in a timely manner. The work is highly effective, environmentally friendly, and significant savings over the alternative. I expect to continue working with Concrete Jack on a routine basis for the foreseeable future. If it is not already clear, I would most certainly recommend Concrete Jack to anyone considering using your services.”

Sarah Gerstein, Broadlands Community Association

“I have had the pleasure to work with Concrete Jack for over 3 years now. The team is very responsive and takes the time to answer any questions the Board or Directors or myself may have. I have found Concrete Jack to be extremely competitive in their pricing and the quality of work is by far one of the best in the area. I have used CJ not only for sidewalks, but also for sinkhole and stormwater prevention. They are a great company and I will continue to use them in the future.”

Matthew Hallman, United Property Associates
