"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."

Customers say: Super punctual

I can fix most things around the house, and I love assembly jobs! I have been doing handyman work since i was about 7(I'm 21 now) when my dad passed. I will be the main one showing up to complete the job as I am owner operated and ran(with the exception of a helper depending on the size of the project) My flexibility is matched by none, you need someone at night? during the morning? Do you work odd hours? Leave it to Sebastian!

"It was glued on and the glue did not stay. He returned to do other work and he re-glued the plastic. It has come apart again. It is not going to stay and now I have to hire someone else who knows what to do to repair it."

"The first engineer plan I received was on letter size paper as a PDF with blurry letters and numbers. No one could read it, not even with a magnifying glass. It did not meet the Montgomery County Building Permit inspection. IThe engineer explained everything well when he came to the house but did not provide a plan that met the requirements of Montgomery county. Because I lived far away I had to send my check US Postal mail and wait for the plan to be emailed to me which had me worried about whether I would be scammed. I offered to come to the engineer with the check but he turned me down. I had to have 3rd party conference call to get things going right."

Structural Engineering questions, answered by experts

Yes, walls on the top floor can be load-bearing if stacked on the floor’s foundation.

Structural engineers are necessary for projects involving alterations to load-bearing structures, foundation work, and compliance with safety standards. This includes home expansions, retaining walls, and significant repairs that impact a property's integrity.

Structural engineers typically charge between $100 and $250 per hour, but many jobs won’t be based on a per-hour fee. Instead, the structural engineer will offer a flat rate for the inspection and structural calculations. The flat rate for a structural engineer costs an average of around $550, but you could see prices ranging from $300 to $800, depending on the complexity of your project and how easy it is to access certain parts of your home for the inspection.

Yes. Foundation walls are always load-bearing.

Absolutely, as it ensures designs are viable and won’t compromise structural integrity.
