"I called JES Foundation Company for a free inspection of my crawl space. I was concerned about a crack in my foundation wall. JES inspector Richard Sheman Showed up to inspect my foundation. He sent a text with the time of his arrival. He was pleasant and on time. He went into my crawlspace and inspected the crack in the wall and stated I had nothing to worry about. He was very knowledgeable about the foundation and itâ  s structure. He explain to me how I could fix the superficial settling crack and save a bunch of money. I appreciate the honesty of the business and I would recommend it to anyone who had the same concerns, and for any of their other services. Ron P Home owner."

"We got 5 estimates from companies regarding a leak in our office and adjoining storage unit. This was the only company that accurately pinpointed the problem , which was a leak coming from gaps surrounding our electrical conduit pipe. Other companies had quoted us 6400$ to dig up the front yard and redo everything from the outside. Others wanted to dig up the inside. I’m so glad Mike explained everything to me clearly- and it all came down to common sense. These guys found the exact spot where the leak was coming from, and knew how to fix it. He also suggested replacing our sump pump because it was the original, and mud was starting to back up. He suggested we do this as it would be tragic to fix one problem and have another occur (and subsequent flooding) that could have been prevented. There was a minor connectivity issue with the sump pump a couple weeks later but I called at 9 am, the man who took the call put it in as an emergency because of some water splashing out and the problem was fixed by 11 the same day. Great responsiveness and customer service. I feel confident in my decision to choose this company, and would recommend them to others."

"We had 2 foundation cracks running from corner of basement window to the floor. Their recommendation was not to just fill in the cracks, as others suggested, but to also reinforce the structural integrity of the foundation with a solid steel plate bolted over the repaired crack. That approach made much more sense to me than the other recommendations I'd received. I hired them and they were onsite within 2 days and completed all work in a single day. We've since had excessive rain and the repairs have held up and the basement is still dry."

"Jobes did a fabulous job. Came to our house twice with several samples so we could match pavers on existing walkways. Removed existing patio which had settled against the house, resulting in standing water against the foundation. They were very careful not to disturb plantings adjacent to patio. Workers were meticulous in laying new patio, which included a circular medallion in the center. The same care and attention to detail was taken while laying the edging stoned along the walks. Jobes did such a great job that we are having them return to add edging to the remaining walks on our property. Highly recommend them!! Great value for the money!"

"Quoted me on a Sunday, started that Tuesday, finished and cleaned up on Friday. They worked hard and did an excellent job fixing my foundation and made everything look like new again. Cleaned up after themselves, including power washing the dirt off my driveway and sidewalk. Their prices were more than fair, and they responded quickly to my questions. Would definitely hire again."

"Dave came out to give me an estimate on fixing what I was hoping was down 3 ft dig, after explaining my options I chose to go all the way down 6 ft and I was happy that I had. Alex the owner and his crew came out, they dug out the foundation, showed me where the cracks were and came back the next day to finish fixing the cracks installing the waterproof barrier, regrading and filling in the trench. They were professional, on time and amazing to deal with. When they left you would not have known they had been there except for the lack of grass on that side of the house. I would recommend this company to anyone needing their foundation fixed"

"John the owner came by and we did a walkthrough of the projects and he offered suggestions as well. I needed small odd jobs done: Dog gate installed,deck debris removed and shed doors secured. John did the work as scheduled,on budget and delivered on what he said he would. He is a local resident,knows the area and is a family man. I would highly recommend Reilly Home Services for your home projects."
