"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."

Welcome to APAC Engineering, Inc. It is our goal to provide structural engineering services to the residential community. We strive to bring knowledgeable and courteous service to homeowners, real estate agents, and homebuilders. Our mission is to provide excellent engineering quickly and at a fair price. There are several reasons for hiring a structural engineer to look at your home. First, you may have a crack in your foundation that you're concerned about. Next, a contractor might have proposed an expensive repair to your home stating that it was a structural issue. Finally, a home inspector might have noticed a structural defect in your home and recommended that a structural engineer look at it. There are many good reasons to hire an engineer but the biggest advantage to a homeowner is that the engineer does not perform the construction work. Therefore a structural engineer does not have the conflict of interest that a contractor would have when recommending work. On the contrary, it is our goal to reduce construction costs to save you money while a contractor wants to increase construction costs to improve his bottom line.

"Robert was thorough and knowledgable. Very helpful! We would definitely call on him again. A great guy and a great job!"

Structural Engineering questions, answered by experts

Structural engineers can perform various inspections on different structures in your home. These inspections usually include a report detailing the engineer’s findings and recommendations for repairs so you can determine your next course of action for repairs, replacements, or new builds. Some of the most common structural engineering reports include:

  • Full home inspection: $350–$1,000

  • Foundation: $300–$800

  • Load-bearing walls: $300–$1,000

  • Roof: $150–$600

  • Chimney: $200–$500

Yes, you can put a doorway in a structural wall; in fact, most exterior doors are set into structural walls. The project is a little more challenging than installing a door in a non-load-bearing wall because you need a structural engineer to assess the wall and make sure it’s safe to create a wall opening. Your engineer’s report will include instructions for your contractor on how and where to install additional supports, like steel headers above the door, to distribute the weight above to the wall on either side of the door.

A construction manager is particularly useful in the case of a large-scale build with custom design elements, so it’s usually worth it to hire one. They can help manage your budget, maintain quality control, oversee timelines, and navigate unexpected hurdles. While construction managers are pricey, they can actually save money in the long run by identifying cost-saving opportunities and ensuring the project stays within budget.

Dormers must be able to bear the load of their own construction and the added window. The style of the dormer, however, will determine where the weight loads onto your home's structure. A gable dormer bears the weight on the side walls whereas a shed dormer bears it on the front walls.

In many areas, advice from a structural engineer or an architect will be required by your building department before you can remove a wall, but even if it’s not necessary, it’s a good idea. Accidentally removing a load-bearing wall—even if a general contractor advises that it’s safe—can cause major structural damage, putting you and your family at risk and potentially costing thousands or tens of thousands of dollars in property damage.
