What moves the price
Plumbing prices turn on access (open walls, finished ceilings, a crawl space), the age of the pipes, whether fixtures move, and the permit and inspections the job needs.
How to compare estimates
- Give every company the same scope, in writing, so the prices compare.
- Check what each estimate includes: permits, disposal, patching, cleanup and warranties.
- Ask how changes are priced once work starts.
- Never pay most of the price up front.
