"My husband and I hired Joe Gibbs and his hard-working crew almost 3 years ago, and it has continued to be such a wise and lucky decision for us ever since! Joe's depth of knowledge about plants, shrubs, and trees is amazing, and his gardening designs give us full color and seasonal enjoyment all year long. He saved us money right from the beginning by transplanting our failing large and small shrubs and plants into areas where they are now flourishing in other spaces in our yard. He also saved our five Crepe Myrtle trees when other landscapers we had interviewed said they were unsavable. Joe is very honest and likable and has a mellow and good-natured personality. On every visit he always takes the time to chat and get a feel for what we think we want, but he also uses his excellent judgement and experience to sometimes prevail with his 6th sense of what he needs to do, and he's always right!! He personally instructs his crew on every nuance, and they work very hard and do a total cleanup every time. As my husband and I are aging, we're depending on Joe and his helpers more and more, which gives us great relief. We both feel so fortunate to have found Joe Gibbs and Springhill Gardens and Landscaping."

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.
