A & D Contractors LLC.

A & D was formed in 2025, and the state lists Andrew Macarthur and Danielle Campbell as principals since that year. Washington registers it through L&I as a general contractor, and Idaho's Division of Occupational and Professional Licensing carries a separate registration, which lets it take jobs on either side of the line. The company says it is family-owned and that it stands behind the result of its work. Its workers'-comp classes, wood frame building and sheet metal, point to the kind of job it is built for: a pole barn or shop with metal skin, a residential build or remodel, or a reroof in steel on a house out toward Deer Park. That mix suits a homeowner in northeastern Washington or northern Idaho planning a pole building, a metal roof, or custom residential work with a small local team. Larger commercial steel-frame projects sit outside the work its state classes describe. As a young business that works largely through its own channels and contractor directories, it fits someone comfortable talking scope directly with the people who run it. Inland Northwest weather shapes this trade. Snow load matters for pole buildings and metal roofs north of Spokane, where winters run longer and heavier than in the city, so ask how a design handles it. Freeze-thaw cycles heave poorly set posts and footings, which argues for setting them deep and on well-drained ground. Dry summers and early fall are the easiest window for framing and roofing, and that window fills up, so planning a spring or summer build over the winter tends to pay off.
