"I would (and almost certainly will) work with AGGO again! We are buying a house and something came up where we needed a structural engineer to inspect something on very short notice. I reached out though Angi's to any company that might possibly employ structural engineers and Linda, a Structural Engineer with AGGO got back to me right away, first thing in the morning and was able to squeeze us in that very night. Linda was thoughtful and thorough. She careful looked over everything and even brought a large, bright light since it was after dark. She took her time, answered all of our questions, and gave us advice on other concerns and things to watch out for as well as reassuring us about things we didn't need to worry about in this situation. Even though she was probably working past her normal work hours to squeeze us in, nothing felt rushed or hasty. "

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

A 4-inch-thick concrete slab can support around 4,000 pounds per square foot if a contractor reinforces the slab with rebar, while that same slab without reinforcements will support closer to 1,000 pounds. For the purposes of a patio, 4 inches in thickness without reinforcement should suffice unless you’re installing heavy kitchen equipment or a hot tub on it. In those cases, reinforcing your slab and sticking with 4 inches of thickness should provide plenty of strength.

In framing, studs are placed at 16-inch intervals to coincide with the typical spacing of wall materials such as drywall or plywood. This spacing is called "on-center" and is necessary for maintaining structural stability and efficient use of materials. The 16-inch spacing also helps to distribute the weight evenly across the building's structure. For those looking to cut material costs and improve energy efficiency, 24-inch stud spacing can be employed through a method called "advanced framing". This requires careful planning and adherence to local building codes to ensure 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.

Yes, ceiling joists are typically load-bearing. However, their primary function is to support the weight of the ceiling and loads applied to it, like lighting fixtures and ceiling fans. They can also help support the roof, especially if they’re part of truss systems. Remember, the load-bearing capacity of ceiling joists depends on the material, size, and space between them. 

Yes, a one-story house can have a load-bearing wall. The load-bearing walls in a single-story home are usually the exterior walls. If the house has a basement with exposed walls, the arrangement of the beams can help indicate what walls are load-bearing.
