I am a licensed Professional Engineer providing structural engineering services for residential and small commercial projects. I work with homeowners, contractors, and design professionals to help move projects through the permit process by providing structural calculations, drawings, evaluations, and engineering letters as needed.\n\nIn-person structural inspections are available in Maryland, DC, and Northern Virginia. Remote structural consulting is available in Delaware and North Carolina.\n\nTypical projects include load-bearing wall removal, beam and header sizing, additions, decks, foundation concerns, and framing evaluations. My goal is to provide practical, code-compliant structural solutions that are clear, efficient, and tailored to the project.

"Arius is a life saver... literally. I had just purchased a new home and was having some renovations done. Simple as they may have seemed, it involved moving a door in the hallway a few feet. Had I not called Arius in for a review, the contractor I had hired (who was a great GC and very professional to deal with by the way) would have made a grave error which would have resulted in major structural integrity failure costing tens of thousands of dollars to repair. The Arius team was quick, responsive and one of the best experiences I had in dealing with contractors and engineers."

"I was really under the gun due to a prior Architectural firm not performing their duties per building plan codes. Not only were the plans incomplete but the City Plan Reviewer states(The Worst plans he’s ever seen) they will not make adjustments unless there is an additional charge for Thousands. Evaluation’s saved my clients and drew our project per code, along with Engineering in less time then they quoted. I highly recommended them, Especially Kirsten. You went above and beyond trying to coordinate this project. The staff was very professional and I will use them on all my projects. Sincerely, Frank B BCM Builders"

Structural Engineering questions, answered by experts

In Lewes, contact a structural engineer if you notice foundation cracks wider than ¼ inch, uneven or sloping floors, or doors and windows that suddenly stick. Visible damage to beams or load-bearing walls, especially after severe weather, signals a need for professional assessment. Minor drywall cracks or isolated roof leaks without structural symptoms typically require general repairs rather than structural engineering expertise.

Helpful?

Before starting a structural engineering project in Lewes, confirm if your property is in a flood zone or historic district, as this can affect approvals. Arrange for underground utility marking and review any local environmental restrictions, particularly for waterfront or wetland sites. Plan your project schedule to avoid hurricane season, and select professionals with experience in coastal and historic structures to minimize unexpected challenges.

Helpful?

Homeowners in Lewes should factor in the high water table, sandy soils, and flood risks, all of which influence foundation design and moisture control strategies. Salt air accelerates metal corrosion, making material choice critical. Many properties fall under historic preservation rules, requiring extra approvals. Seasonal weather, hurricane threats, and peak tourism can affect project timing, contractor schedules, and access to materials, so plan accordingly.

Helpful?

For Lewes homes, it’s smart to keep a digital moisture meter for monitoring foundation dampness, along with a dehumidifier to manage indoor humidity. Use marine-grade sealants and stainless steel fasteners to protect against salt air corrosion. Crack monitoring gauges and a sturdy level help track shifts in load-bearing walls. Emergency supplies like tarps, a submersible pump, and a generator are essential for post-storm stabilization.

Helpful?

In Lewes, structural engineering maintenance often involves regular inspections for salt air corrosion on metal components, especially in load-bearing walls and connectors. Homeowners should monitor foundation moisture using a digital meter due to the high water table, and check for shifting or settling after storms. Waterfront properties need frequent assessments of piers and pilings for marine borer damage. Maintaining clear drainage channels and flexible expansion joints helps prevent freeze-thaw and humidity issues.
