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.

"They were excellent. They quickly made a draft that only needed 3 minor adjustments. The final product was exactly what I needed. They referred me to a structural engineer for review. The whole process took half of the time that they initially estimated. I would definitely use them again."

"I had a fantastic experience working with this drafting firm. From the very first phone call, Kirsten?our drafting consultant? was clear, professional, and incredibly helpful. She explained the entire process in detail and made sure all of my questions were answered up front, which gave me immediate confidence in the team. This firm partnered with engineers and architects to get the best quote for me on a stamp for my plans after they did an exceptional job on drawing the prints that met all the requirements for permitting. Their coordination and attention to detail made the process very simple on my end. If you are looking for a highly capable drafting firm that knows how to get things done right, I highly recommend them!"

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?

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?

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.

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?

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.
