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

The National Association of Home Builders requires repair of any foundation crack of more than one quarter of an inch, although local regulations may vary. In general, any visible crack that is growing in size, allowing water through, or that you have just noticed, is a good reason to call a structural engineer. Cracks can be a sign of a sinking foundation, so an inspection is a good idea for your peace of mind.

The process involves initial consultation, concept development, detailed planning, regulatory approvals, and integration of contractor work for project execution.

It depends on the bank and the extent of the issue. Some banks will lend against homes with minor foundation damage, but most won’t if the issue is structural since the home acts as collateral for the mortgage. Banks that offer renovation loans might still finance a home with structural problems. More minor issues like settling cracks and intermittent problems with humidity are unlikely to stop a bank from financing.

A split-level home is one that has several staggered floors connected by short staircases, while a split floor plan separates the primary bedroom from the rest of the bedrooms. Split floor plans are most often found in single-story homes, while split-level homes are always at least two stories.

A structural engineer’s report is almost always worth it, as it can help you avoid buying or overpaying for a home with structural issues. The most important thing the report does for you is provide peace of mind that you won’t have to pay thousands of dollars for structural repairs right after closing on a property.
