"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."

"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."

Levelift Systems was founded in 1991 by Mr. Paul Mauer. Over the next twenty-three years, Mr. Mauer developed a highly respected specialty foundation contracting company, serving the State of Maryland. Unfortunately, Mr. Mauer died tragically in 2014. Levelift Foundations, LLC was formed as a means of keeping the core of Levelift Systems together and continuing to be a leading installer and foundation designer, for the CHANCE helical pier system, in the state of Maryland. Our certified helical pier installers are trained and certified by CHANCE® and we offer both residential and commercial foundation solutions in Maryland and the surrounding areas.

"Workman took three days to shore up the foundation of this very old garage. He was polite, and did a nice job. Estimates from several providers were all over the map, since some recommended extensive work involving the use of helical piers, and installation of a new concrete block foundation. I went with more conservative repair.. It looks fine, and I hope I made the right decision."

Structural Engineering questions, answered by experts

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

Clean regularly, treat wood for weather resistance, and inspect for damage to ensure longevity.

Trusses and rafters each have advantages and disadvantages, so one isn’t necessarily better than the other. For example, trusses are more affordable and often come in prefabricated kits, so they’re easier to build than rafters. However, rafters are available in a variety of designs, so it’s easier to find one that fits your style preferences. Plus, if you want to build an attic at some point down the line, it’s far easier to do that with rafters rather than trusses.

Because of their composite structure, cutting or drilling LVL beams can compromise their integrity. We strongly advise contacting a general contractor or structural engineer before making any alterations to LVL beams. Professionals can also answer questions about choosing between a pier and beam versus slab foundation when designing your project.

Whether you’re building a new home or building an extension on your existing property, you will likely need both a structural engineer and an architect. A structural engineer will determine what loads your foundation and framing can safely handle, and an architect will draw plans according to those structural calculations to simplify the building process. You can start by contacting a structural engineer near you, as many work alongside architects and can get all of the prep work done at once.
