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

By careful planning and reinforcement to maintain structural integrity.

No, a structural engineer is not the same as a builder. A structural engineer is an expert in all things related to the structural integrity of a building. The structural engineer is responsible for calculating the correct materials in terms of load-bearing capacity and overall structural safety. Structural engineers do not perform the actual building of the house or other structures. Rather, the builder executes the plans and designs specified by the structural engineer.

Most lenders and homeowner’s insurance companies don’t mandate a structural engineer’s inspection, so in most cases, it’s not required. However, it’s a good idea to have one done anyway to ensure you know what you’re buying. You can use the report to carry out repairs after closing or even to negotiate the sale price before closing.

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.

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.
