If you've gotten wildly different quotes from contractors, here's why.
Slab-on-grade vs. pier foundation vs. crawl space — each has different costs. Coastal soil often requires engineered footings, adding cost vs. inland NC.
Coastal Brunswick, Pender, and New Hanover counties have stricter wind zone requirements than inland NC — affecting framing, fasteners, roofing, and door ratings.
Larger or complex structures require engineered drawings. Permit costs vary by county. We include permit coordination in our estimates.
Running power to a detached structure, upgrading a panel, adding a bathroom — these are significant additions that low-ball quotes often leave out.
Grading, clearing, poor soil — site-specific prep can range from minimal to substantial. Our estimate visit accounts for this upfront.
These ranges are a starting point. The only way to know your specific cost is a site visit and detailed scope. Our $250 paid estimate goes directly toward your build.
