We discovered a leak in our master bathroom tub/shower area about one week prior to Advance Plumbing making the repair. Prior to their analysis we had two other plumbing companies provide us with analysis of the problem, recommended solution, and estimates for the repair. Each of these companies did a visual inspection of the plumbing, shower walls, shower pan, and surrounding walls. Each recommended that the entire shower/tub area must be demolished and all new walls and fixtures installed for a complete. Cost for this started at around $15,000. The Advance Plumbing plumber tested the plumbing, shower floor, and pan under pressure, not just visually, and identified our problem as leaks in the shower and tub plumbing fixtures due to age and gradual disintegration. His solution was to install all new hardware and plumbing for both tub and shower at a cost of $3,000. To date, this repair is working, with absolutely no leaks. We are extremely grateful to Advance Plumbing for their accurate analysis of our problem, saving us a great deal of money and mess. They guarantee their work, adding to our satisfaction with their work.
