"DO NOT LET THEM IN YOUR HOME WITHOUT PROOF OF LIABILITY INSURANCE! BEWARE! This company and its inspector, C. Scott Burns, do not follow accepted home inspection standards and caused thousands of dollars in damage to my property during a home inspection. Despite providing pictures, documents, and fulfilling every request, the owner, Jeffery Donaldson, refused to pay for the damage. He only communicated through a generic customer support email and repeatedly refused to identify himself. A quick search of court records in Berkeley, Charleston, and Dorchester counties will show that he has been involved in numerous lawsuits. I have been forced to seek legal action as well. STAY AS FAR AWAY FROM THIS COMPANY AS POSSIBLE. If you are buying or selling a home in the Charleston, SC area, ask who the inspector is and ensure you get a copy of their insurance policy before allowing them into your home. They will refuse to repair any damage caused by their incompetent inspectors. I am extremely disappointed in this company and its owner, Jeffery Donaldson. I will never let this shady business near any of my homes or my clients’ homes. I want to warn everyone to avoid the same painful process I and many others have experienced. There are many other reputable, knowledgeable, and well-trained inspection companies in the Charleston area, such as Cardinal, Hometeam Inspections, or literally ANYONE ELSE besides ACE Preferred Inspections."

Structural Engineering questions, answered by experts

While concrete walls do not need to "breathe" in the traditional sense of the word, they do require waterproofing and dehumidifying methods, particularly in basements below the water table. Concrete both contains moisture from its initial installation and can absorb water when exposed. Ensuring proper basement ventilation , installing a vapor barrier, and controlling water exposure are all important tasks.

Yes, you can put a doorway in a structural wall; in fact, most exterior doors are set into structural walls. The project is a little more challenging than installing a door in a non-load-bearing wall because you need a structural engineer to assess the wall and make sure it’s safe to create a wall opening. Your engineer’s report will include instructions for your contractor on how and where to install additional supports, like steel headers above the door, to distribute the weight above to the wall on either side of the door.

It's safe to assume that all exterior walls are load-bearing, or at least have load-bearing characteristics. Some older homes feature porches or bump-outs that don't rest on the home's foundation. However, they still must carry the weight of the roof section they support. Walls containing floor-to-ceiling glass or other non-structural elements must use post and beam configurations to meet load-bearing criteria.

Squeaky floors don’t always mean structural damage. Usually, it’s caused by friction somewhere inside your floor—whether it’s a loose floorboard or a gap between the subfloor and joists. If there is structural damage, you’ll notice other signs like soft or sagging floors, cracks that go from the wall to the ceiling, and horizontal cracks on your foundation.

Structural engineers typically charge between $100 and $250 per hour, but many jobs won’t be based on a per-hour fee. Instead, the structural engineer will offer a flat rate for the inspection and structural calculations. The flat rate for a structural engineer costs an average of around $550, but you could see prices ranging from $300 to $800, depending on the complexity of your project and how easy it is to access certain parts of your home for the inspection.
