"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."

"Prior to any demolition work, I called on Zign Consulting to help me figure it out whether it would be simple or complicated to remove two walls that were separating the kitchen and living space.

Structural Engineering questions, answered by experts

The standard thickness for an LVL beam is between 1.75 inches and 7 inches. However, you can order LVL beams in non-standard sizes as well. When you work with a contractor, they can source beams that are the appropriate size for your project for you after assessing your blueprints.

Yes, water damage can affect your walls' structural integrity. If the water or moisture sits on the walls for an extended period, it can weaken the drywall, plaster, wood framing, and other materials supporting the wall. That's why it's critical to dry out the area as soon as you notice it.

Yes, you can build over a stump if the roots are no longer alive. Living roots will continue to grow and may damage your new construction over time. Similarly, you should also remove rotting stumps because they may continue to attract pests and even cause new structures (especially those made from wood) to decompose as well.

The 10 10 rule describes the formula most contractors use to determine how much to charge for a job. Allowing for 10% overhead above the total projected cost to do the work and 10% profit sets a contractor up for success, even if there are delays or other problems on the project. This formula isn’t a hard-and-fast rule, but it is a ballpark figure to begin with when estimating your expenses on a job.

The easiest way to tell if a wall is load bearing is to check if it’s an exterior wall or if it runs perpendicular to the joists above and below it (or parallel to beams). Exterior walls are almost always load-bearing, and walls that run under beams or parallel to them are also usually load-bearing. There are exceptions to these rules, and walls that don’t fit into these categories can still be load-bearing. If you’re unsure, hire a structural engineer to look at your home to assess whether or not the wall is structural.
