The work is scoped against what your house actually is: its framing, its wiring vintage, whether the walls you want gone are carrying load. That assessment is what turns a rough budget into a number that holds.
Permits are pulled before anything is opened up. Work done without them surfaces at resale, when an inspector flags unpermitted square footage and the sale stalls.
Dry summers and wet winters concentrate water intrusion into a few months, so flashing and drainage details that hold are what matter most.
What the job includes
- Design and layout planning
- Permit filing and inspections
- Structural and load-bearing changes
- Electrical and plumbing rough-in
- Flooring, drywall and finish carpentry
- Final walkthrough and punch list
