How long does a typical home remodeling project take?
Project timelines vary depending on complexity and scope. A kitchen or bathroom remodel may take several weeks, while large-scale additions or full-home renovations can span a few months.

At SEI Construction, we simplify your project by integrating the design and construction phases under one roof. It begins with a detailed consultation to understand your style, budget, and goals.

Because everything is managed internally – from permitting to finishes – you benefit from smoother coordination, faster timelines, fewer surprises, and one point of contact throughout.
