Bathroom Renovations in National City

Most bathrooms in National City are small, original to the house and overdue. All Pro Contractor renovates bathrooms in the city's older homes, where the plumbing and the floor under the tile matter as much as the finishes.

What an older National City bathroom hides

  • Cast iron drains and galvanized supply lines near the end of their life.
  • Subfloor softened by decades of small leaks around the tub and toilet.
  • No exhaust fan, with a window as the only ventilation.
  • Plaster walls and tile set in a thick mortar bed, which take longer to remove.
  • Wiring without the protected outlets a bathroom needs today.

Fix the floor before the finishes

In a raised-floor home, a long-running leak rots the subfloor and sometimes the joists below it. This is found when the old tub comes out. Repairing it properly at that point is what keeps new tile from cracking and a new toilet from rocking.

The crawl space helps too. Drains can be replaced and moved from below without breaking concrete.

Getting more from a five-by-eight room

A typical older bathroom here is small, often about five feet by eight. A walk-in shower in place of the tub, a wall-hung or narrow vanity, a recessed medicine cabinet and a pocket door all free up floor space without moving a wall.

Ventilation and permits

An exhaust fan ducted to the outside is one of the most useful things a remodel adds to an old bathroom. It is what stops peeling paint and mildew from coming back.

Plumbing, electrical and structural changes need a permit from National City's Building Division.

How a bathroom remodel with All Pro Contractor runs

  • Site visit to review the room, the plumbing and ventilation, and what you want to change.
  • Written estimate with scope, allowances and responsibilities for design and permits.
  • Selections and ordering, so tile, fixtures and glass are on hand before demolition.
  • Demolition, rough plumbing and electrical, inspections, waterproofing, then tile, fixtures and finishes.

Questions

Frequently asked questions

What if you find rot under the old tub?

It gets repaired before anything new goes in. The damaged subfloor is cut out and replaced, and joists are reinforced or replaced if they are affected. The estimate should explain how hidden damage like this is priced.

Does a bathroom with a window still need a fan?

A fan vented outdoors is the reliable way to remove moisture, and current codes generally require mechanical ventilation in a remodeled bathroom. A window alone rarely gets opened on a cold morning.

Should old pipes be replaced during a bathroom remodel?

If the walls are open and the house has galvanized supply lines or deteriorated cast iron drains, yes. Replacing them now costs far less than tearing out new tile to do it later.
