Get matched with top foundation repair specialists in Finksburg, MD

"I hired JES to install a trench and sump system into the basement of a new house I purchased. After the job was completed, I noticed the cellar stairwell was pooling water. They returned and said that they didn't think that the drain was run direct to the sump as it should have been but they needed to open the concrete to verify. I also asked why there was no water in the sumps. They ran tests with water for 2 hours and didn't see water and tried to explain to me that it was expected since the water was running out around the drainage under the foundation. They even had a supervisor try to explain to me over the phone when I questioned it. It took them several weeks to return to fix the cellar drain and sure enough, the pipe was just run to under the foundation and not directed into the trench/sump. A repair team came out and busted up the concrete to correct it. In doing so, they saw that their trench was also not connected to the sumps at all, which is why I never saw water in the sumps and not the mysterious theory they tried to convince me of weeks prior. This is terrible that there is no inspection of work prior to covering it totally with concrete. Or further, there was no physical test of running water in the system to verify the sump works. The repair team that came out were wonderful and did everything correct. After this, I called 3 times and asked for a manager to call me to discuss this and never received a response. The salesman stopped answering my calls. As a note, after spending $30K on this upgrade to my house, it was in worse risk than prior to JES so if you choose them, be careful."

"Dan was highly professional and offered an excellent evaluation of my needs. He actually went into the crawl space to better understand my needs. A good neighbor and a person to know. Thank you."

"Quick, efficient, super communication, great cleanup. Highly recommend."

"We hired this company for a second time this year to do major work on the concrete outside our home. We had our front porch, steps and patio redone: old concrete demolished and removed, new concrete installed, with new stucco on the foundation, and white vinyl railings installed. The finished work exceeds our expectations. For other home owners, I would recommend them. Zachary and Nick are genuinely nice. They oversaw the project and there was good communication throughout. They paid attention to my concerns, and had good ideas about the concrete dimensions and railing placement. The crew did an outstanding job, were respectful, and did a thorough job of yard cleanup. Shoutout to Juan for keeping me informed about progress every day - thank you. I am pleased to support this local business and recommend for concrete work."

"Steven was very nice and easy to do business with very honest and gave me all kinds of options. Hard to find people like that nowadays just overall great quality people"

"Fast response, fantastic results, and they had the job done in one day. Before leaving they checked to make sure everything was completed to my satisfaction. I would highly recommend them to anyone needing concrete work done. "

"Shoppers beware, this company has 11 bad complaints in the last 3 years according to the Baltimore license bureau, and my complaint will be number 12, and should not be in business, seriously folks , they cheated me by not using gravel under the concrete and no expansion joints, when asked to redo the driveway, they put me on the back burner for 2 months, work performed in August of 2025, when they decided to finally come out, they ripped up my driveway and apron and left all the debris in my yard, after 2 weeks of calling them to remove the debris and getting every excuse they can give, along with broken promises, I had the debris removed , more money out of my pocket, here is November 2025 and they still will not come out and take care of this issue, the owner of this company Jack will not take phone calls , and when he decides to return your calls , very irritating, he does not honor his warranty and you will be ignored very bad company to deal with"

"Got the job done as promised."

"Avoid Guardian Basement – False Promises and Poor Customer Service Two years ago, I hired Guardian Basement to fix a water issue on the front wall of my basement. Joel came out, sold me on their system, and guaranteed I would have a dry basement. We also replaced two sump pumps and had the sump well dug deeper. The main selling point was their lifetime guarantee. Fast forward two years, and I have the exact same problem. Every time there is significant rain, water rushes through the same wall. I reached out to Guardian Basement, and Joel scheduled a time to check it out. His tone was completely different this time—defensive and dismissive. Within five minutes, he claimed, “Your system is clogged.” He made this assessment without any real inspection—just by looking at the cement floor and wall. Now, here’s the catch: If you look closely at their so-called lifetime warranty, clogs are not covered. So despite spending thousands of dollars, I’m back to square one. To make matters worse, Joel was incredibly condescending and unpleasant to deal with. After this experience, I looked into their licensing with the state of Maryland and found multiple complaints against them. I am now in the process of submitting my own complaint as well. I would never recommend Guardian Basement to anyone. Save your money and go with a company that truly knows what they are doing and stands behind their work. If I could give them a negative number of stars I would."

"Everything perfect couldn't have asked for better help for my parents basement. All dry and feeling fine."
