"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."

'58 Foundations
'58 Foundations
For over 66 years, '58 Foundations & Waterproofing has provided the highest-quality basement waterproofing, crawl space encapsulation, foundation repair, and mold removal. We lead with a promise of Trusted Five-Star Service, which means the customer experience is at the center of everything we do. Since 1958, we have been steadfast in keeping this promise and upholding the values upon which '58 Foundations & Waterproofing was built: trust, teamwork, integrity, respect, and communication. From the initial call to job completion, our customers are met with knowledgeable, caring, and professional staff prepared to offer a five-star experience that is unmatched in the home repair industry. What’s more, you can enjoy the peace of mind that comes with our lifetime warranty and our industry-unique money-back guarantee!
"If you’re considering 58 Foundations, do yourself a favor and stop right now. I cannot, in good conscience, recommend this company to anyone. Their complete disregard for accountability is infuriating. At first, things appeared to go smoothly, but the illusion of competence quickly disintegrated when it came time for the building inspection. The city inspector requires a letter from the project engineer verifying that the work is safe, sound, and compliant with code. 58 Foundations flat-out refuses to provide this basic validation of their work. Why won’t they stand behind their project? Are they hiding shoddy, substandard work? As a homeowner, I’m now saddled with the mess of an open permit and no resolution in sight. This is unacceptable. If a company won’t back their work with a simple letter, what does that say about their integrity—or lack thereof? Didn't expect this kind of run around from a well established professional firm, save yourself the headache."

"SCAM ALERT!! We had Chris Morrow under contract for all the HVAC work to be done at our home which was a complete rehab. We paid him a portion at the beginning of the job once contracts were signed to begin work. At first things were okay, He came to install all the ducts. Was on time, but unprofessional by bringing along his kid (or someone else kid, I'm not sure). Then, we have him a check for $2500 to purchase both units and the rest of the material needed. That was 2 weeks ago! (july 31st) He called to say the material wasn't in yet on Tuesday July 31st. Then said it would be there the next day. So for the rest of that week, he continued to say the same thing. Then he started not answering his phone but maybe once or twice. My husband and I both have tried calling several times and have not heard from him since Friday, Aug. 12 at 7am stating he had the material and was on his way to the property. We have not see. Or heard from him. Now we are out $2500 And have no materia!! We have left multiple messages and texts. He let's the phone ring once or twice then hits the "ignore" button on his phone. I will contact anyone and everyone I can to be sure no one gets scammed by this man!!!"
