Project approach

WHAT HAPPENS BETWEEN DEMO DAY AND YOUR FIRST SHOWER

Bathrooms bring plumbing, electrical, ventilation, waterproofing, and finish work together in a compact space. Improper work can lead to leaks, moisture damage, or subfloor problems later.

After demolition begins, we inspect exposed framing, plumbing, and subfloor conditions before rebuilding. Hidden conditions are sometimes discovered during demolition, especially in older homes.

Questions

What homeowners ask us

Do I need a permit to retile my shower?

Cosmetic finish work may be permit-exempt, while plumbing, electrical, structural, and layout changes may require permits. We verify the exact scope and address.

What affects the timeline for a bathroom remodel?

Layout changes, trade scheduling, inspections, material availability and waterproofing cure times all affect the schedule. We plan the work in sequence and confirm timing for your project before construction begins.

What happens if you find hidden damage during demolition?

Demolition can reveal moisture damage, worn piping or ventilation problems. We document what we find and discuss any necessary changes to the scope, cost and schedule before additional work proceeds.

Can I live in the house during the remodel?

Often, yes, if another functioning bathroom is available. If this is the only bathroom, we discuss temporary arrangements before work begins.

Do you handle the permit paperwork?

We coordinate required permit applications and inspections and explain which contractor or trade is responsible for each filing.
