"Dee is fantastic! We loved the design Mike came up with for our backyard makeover. Then once construction started we realized we had made choices that needed to be changed. In every case Dee's suggestions (stucco the walls instead of paint, don't use DG next to the pool, run wood fence topper horizontally) turned out to the best. We are so glad we listened to him. Our finished backyard looks like an art installation but one where you can feel comfortable and at home. Now a year later we had them come back for a few tweaks and again Dee's suggestions were the right ones. We are happy we choose G & L and plan to use them again next year when we tackle our front yard."

"I worked with Alpha once before, and they assisted with a second project 2 years ago which, now finally completed, I'm able to write a review about. Alpha helped with structural plans for windows in a garden level unit in order to prepare the proposal for city approval. Alpha is a big company and it took them a little while to complete everything; however I can certainly say that the engineer and contact people were knowledgeable and thorough. The plans were approved with their help and now that the unit is permitted for occupancy, the windows are a lovely attribute to the space."

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.
