Home additions
in Wilmington, NC.
SJB Contracting builds home additions in Wilmington and coastal NC. The new room is framed, dried in and finished, with the roof, siding, trim and floors tied into the house you have. We pull the permits where the code requires them and schedule the inspections, and a licensed NC engineer does sealed drawings where the code calls for them. A new bath goes in the same written price.
A new room that looks like it was always there.
Jay has 30 years of building behind him, from custom homes to multifamily. He walks the house with you, works out how the addition ties into the roof, walls and floors, and puts the whole job in one written price.

From the first walk
to the last photo.
Jay walks it with you
Jay comes out, looks at the house with you and talks through what you want and what it will take.
One written price
You get one written price and a schedule before any work starts. If we find hidden damage, you see photos and a written price before anything extra is done.
We run every trade
Our crews and licensed trade partners, hired, scheduled and checked by us. Permits pulled where the code requires them.
Photos the whole way
Before, during and after photos, sent to you even when you are away, and a final walk-through when the work is done.
Straight answers.
What homeowners ask Jay before an addition.
Do I need an architect or engineer?
It depends on the addition. Jay tells you on the walk-through, and we bring in a licensed NC engineer for sealed drawings where the code requires them.
Who pulls the permits?
We do, where the code requires them, and we schedule the inspections.
Will it match the rest of the house?
We tie the roof, siding, trim and floors into the house so the new room matches what is already there.
Can the addition include a bath?
Yes. Plumbing, electrical and HVAC run through our licensed trade partners, all in the same written price.
