Flat Rate Plumbing is built on a simple promise: you should know the full price before the work begins. Every job starts with a single, comprehensive estimate covering diagnostics, labor, and parts, so you approve one clear number up front — no hourly meter running, and no surprises when the work is done.
Roy handles a full range of residential plumbing, indoor and out — water heaters and garbage disposals, plumbing leak and slab-leak detection, drain and pipe cleaning, and repairs and replacements for sinks, faucets, toilets, tubs, and valves. He also handles plumbing for remodels and new construction, helping homeowners plan upgrades with confidence.
Most of all, Roy believes in doing business the straightforward way. There is no middleman and no dispatch center — when you call, you talk directly to the master plumber who will be doing the work. It is the honest, personal approach that has earned Roy decades of loyal, repeat customers throughout the Grand Prairie area.
