"I had a great experience working with A & A Structures LLC for the structural engineering work on my home renovation in Bethesda. They were easy to work with, extremely fast, and delivered permit-ready documents that were clearly tailored for Montgomery County DPS—right down to the correct file naming conventions, which matters more than people realize. When the county requested minor revisions, A&A responded immediately, made the updates without hesitation, and even worked directly with my developer to clarify requirements. All of this was handled under the original fee, which I felt was an excellent value. Professional, responsive, and clearly experienced with Montgomery County’s approval process—I would absolutely recommend them and would use them again without hesitation."

"Working with Zign Consulting has been the bright spot in an otherwise complex construction project. From the beginning, Zign Consulting was everything you hope for: honest, direct, highly capable, and urgent. After months of delays and complications caused by a previous architect, Zign Consulting stepped in and immediately brought clarity and direction. They swiftly got our plans completed and approved by DCRA—something the original architect struggled with for nearly a year. Their communication was transparent, their timelines were accurate, and their professionalism was unmatched. If you're looking for an architectural consultant who will advocate for your project and get things done the right way, Zign Consulting is the firm to hire. I can't recommend them enough."

"Initial rep was great and informative. Felt comfortable with initial sale. Hardly had any contact from customer service except for the payments. There were several delays that we were not informed about unless we called to ask. Took 7 months before they showed up to begin project. Only 1 person was sent to build steps. Took a week. Hard worked, hardly took a break. Had to call again to see when they would come to pour patio. Never knew when they were coming, they just showed up. Hardly spoke with the homeowners. Inspection paperwork was just left on porch. Additional paperwork that is "required by the County" had to be completed by homeowner and taken to Court house to be notarized and filed and also provide a copy back to Long Fence. Time sensitive materials which added to homeowners to-do list. Gave this contract to LF on the surface of their history and appearance of a 'good local company' but should have stayed with original contactors in VA. Puddle of water forms when it rains"

FAQs for engineer structural projects in Rockville, MD

To determine if a wall is load-bearing, start by checking your home’s original plans or asking a structural engineer. Exterior walls always carry weight, but interior ones only do if they sit over a beam or run perpendicular to floor joists. If a wall lines up with posts in the basement or falls directly under the roof ridge, assume it’s load-bearing and call a professional before attempting to remove it with a sledgehammer.

Calculating the wall load and sizing the beam must be performed by experts to ensure structural safety. You need a structural engineer to evaluate all load aspects and determine the proper beam dimensions. A professional engineer performs precise calculations and advises on any necessary enhancements, such as larger footings for support. An inspector then verifies that the revised structure meets all safety and code regulations before the finishing work begins.

Hiring a structural engineer is essential for ensuring your home remains structurally sound during any major renovation. Their responsibility is to deliver expert assessments and design recommendations for load-bearing modifications. The average cost to hire a structural engineer is $500, with rates ranging from $350 to $800. Consulting a licensed, experienced engineer guarantees that every structural project, whether constructing a new home or remodeling an existing one, is completed safely and efficiently.

Almost all load-bearing wall removals require a permit as they support everything above it, and building departments want proof that the new beam can handle the weight. Pulling a permit triggers plan review and inspections that confirm the work meets local code and safety standards. Skipping this step can lead to fines or being forced to rebuild later, so have your contractor pull the permit before work starts.

Removing a load-bearing wall to create an entrance for a carport or covered patio is a task that comes with defined cost implications. This modification requires extra structural adjustments to ensure safety and proper integration with the adjoining space. When you convert a wall into an entryway, you can expect to pay between $3,200 and $9,500, with an average cost of $6,400. The additional work required for this conversion reinforces the home’s integrity and ensures compliance with applicable building codes.
