A remodel lives or dies on sequencing. Demolition, rough-in, inspection, drywall, finish - each stage gates the next, and a crew that books trades out of order is why projects stall for weeks with nothing happening on site.
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.
Freeze-thaw cycling is the governing condition. Water that gets into masonry, grout or a roof detail expands when it freezes and widens the gap it entered through.
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
