We can customize any project and work with any budget. You will admire and adore your new space.
"After I terminated the lease of my tenant in early 2023, I decided to do the whole house remodel before selling it because of the age of the house and TLC it needed. The original contractor I hired ended up going to jail for child abuse charges and I had to find another contractor to finish the job. I got a number of quotes and decided to go with Donna from AND Contractors, LLC. It is very difficult to come into a project that somebody else started and the quotes reflected that but Donna’s estimate was fair and I felt comfortable in my interactions with Donna. Don't let the fact that a woman runs the business fool you - she is a real tough but fair boss. She was on the job site every day! She treats her people right but also lets them know when they mess up and they respect her for it. There were many things that were not visible but needed to be redone where the original contractor messed up but it was important to Donna that the corrections be made. I am sure there must be limits but all of these corrections were accommodated without change orders. The project was completed on time and within budget. Oh, did I mention Donna is also a real estate agent? When the project was completed, she listed the house at the highest price in the history of the neighborhood. I was hoping but not expecting it so it was a pleasant surprise when she brought me a full price contract within a few days! I HIGHLY recommend AND contractors, LLC and Donna! If you want your project done right, on time and within budget, you owe it to yourself to at least have her look at your project!"

You should bring in a structural engineer any time you’re adding or removing something that carries weight—think new construction, a major remodel, or moving a load‑bearing wall. Call one during a real‑estate deal, after storm damage, or when you spot cracks in the foundation, beams, or chimney. An engineer’s report confirms that the structure is sound and tells your contractor exactly what fixes—or reinforcements—are needed to keep the home safe long‑term.
Who you hire depends on the task. Hire an architect to shape the look and layout of your home. Call a structural engineer to verify that load‑bearing elements—walls, beams, foundation—can handle the plan or to diagnose structural issues. Bring in a home inspector for a broad health check during a sale, after a storm, or for an appraisal. Matching the pro to the job keeps costs down and problems in check.
During the visit, the engineer checks your foundation, framing, walls, roof, and insulation, then compares what they see to any existing plans. If the structure matches the specs, you get the all‑clear; if not, the engineer outlines the fixes. Their sign‑off is what lets the next phase of work move forward, so expect clear notes on what’s solid and what needs attention.
Civil engineering is the broad field that covers roads, bridges, and other infrastructure. Structural engineers focus on the loads and forces inside a building or bridge—foundations, beams, and walls—while mechanical engineers design and keep power systems running, from elevators and turbines to HVAC equipment. In short, civil handles the big picture, structural makes sure it stands up, and mechanical keeps everything moving.
Most structural engineers offer free quotes. They’ll look at your home’s size and the scope of work to decide whether a flat fee or hourly rate makes sense. Simple inspections are usually priced by square footage; bigger, more complex jobs require a site visit and a detailed written estimate. Getting that number up front lets you nail down a budget before any drawings or inspections begin.
The engineer reviews every load‑bearing part of the home—floors, foundation, walls, roof, and major beams—along with insulation and the soil around the structure. They also factor in local weather risks and nearby water sources. The goal is to confirm that the materials and construction can handle day‑to‑day loads and extreme events alike, and to flag any spots that need reinforcement.
