We provide structural engineer services for individuals. This typically involves coming out and assessing the condition of a structure and/or its components and determine how to address any structural issues found. It is our mission to provide complete customer satisfaction from start to completion of a project. In order to understand the needs and expectations of our customers, we take great care to work and communicate with every customer in a professional manner. Please understand that we do not do free estimates as we are not contractors. Our work involves coming out to a site, making observations, and taking any required measurements. Following this, an analysis is performed and conclusions are formed to determine how to proceed if any structural deficiencies are determined to be found.

We specialize in basement and crawl space waterproofing. Our experienced team is dedicated to providing effective solutions to keep your basement dry and free from water seepage.

"About 8 years ago, after a brutal series of flooding rains, we started getting water in our finished basement. Eventually over the years it became a huge problem whenever there was significant rain, which happened frequently. In August 2018 we unfinished the impacted part of the basement and obtained quotes for a repair. Seepageseal was by far the most responsive and most reasonable. They did not press us into a large scale expensive solution. They installed a vapor barrier and drain tiles, in addition to a sump pump. They brought in an experienced team that quickly, cleanly and efficiently completed the installation. It is now April 2019 and we have endured numerous rain storms that have flooded our neighbors basements. Their solution has proven 100% successful. We highly recommend this company."

Engikeering provides excellent structural engineering solutions. Engikeering will provide a licensed structural engineer to deliver an accurate assessment of the potential concern and create structural solutions. If you are removing walls, adding openings in walls, adding living space, placing an additional story on a structure or other actions that may impact the structural components of an existing building, it is advisable to utilize a structural engineer to understand the full impact of the renovation. Engikeering will provide full structural design and detailing for new structures, to completely and economically meet all of the applicable building code requirements. Engikeering can help identify the cause, assess the severity of the situation, and provide any needed design to remediate the areas of concern: Foundation cracks, interior cracking and/or framing movement, natural disaster damage, sagging floors or bowing walls, rot and/or insect deterioration, undersized, strained or damaged elements, roof failure or building collapse.

"Beware of this company. I had Jonathan come out to provide me with a verbal report on the condition of some termite damage in my basement. With each visit, he wanted more drywall removed and exacerbated the perceived severity of the situation. I soon realized that he was more problem focused than solutions oriented. I decided that I would prefer to look elsewhere for services to mitigate my issue, and effectively terminated our contract. Jonathan, without my knowledge and with what I perceive to be malicious intent, then sent his partially complete report to the Village reporting my property. Half the report was guesswork as to the extent of the damage as they were about areas that he was not even able to visually inspect. The village, after reading the report, became spooked and are asking for more than I and my professionals agree is necessary to mitigate the safety risk. Needless to say, I will never again use his services and I strongly advise that others be wary as well."

Structural Engineering questions, answered by experts

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.

No, it’s not legal for unlicensed individuals to conduct structural calculations for buildings or building repairs. Not only do licensing requirements prevent DIYers from tackling this project, but mistakes can also be extremely dangerous and put your property and anyone inside or near it at risk of severe injury or even death. You should always hire a licensed and certified local structural engineer to make structural calculations.

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.

Yes, all states require structural engineers to carry the proper license, with specifics determined by each state. You can use Angi’s state licensing tool to confirm that the structural engineer you’re considering holds the required licensing to tackle your job. Hiring an unlicensed structural engineer will not only cause issues with permits but it could also lead to an unsafe building. The cost of a professional, licensed, and experienced engineer is well worth the investment.

Yes, floor joists are essential structural components. They support the weight of floors and everything on them, transferring loads to the foundation and walls. Properly installed joists are necessary for maintaining strength, stability, and structural integrity.
