Toilet Installation and Replacement in Denver, CO
New toilet, same drain. The job is quick when the flange is solid and slow when it is not. Rocking, seeping at the base, or a wax ring that keeps failing usually means the flange needs attention before any new toilet goes on it.
- Standard, comfort height, and one-piece toilets installed
- Flange condition checked and repaired, not shimmed over

What it is
Toilet installation Toilet installation is the process of removing an old toilet and setting a new one, including a new wax or foam ring seal, a securely anchored base, and a properly connected water supply line.
A toilet that rocks or was not sealed correctly can leak at the base without anyone noticing, and in Denver's older homes uneven flooring around the toilet flange makes a solid installation even more important.
The flange decides whether the install lasts
A toilet seals against the closet flange with a wax or waxless ring. If the flange sits below finished floor level, is cracked, or has pulled its bolts out of the subfloor, the new toilet will seep no matter how good it is. That gets fixed first.
- Correct rough-in measured, usually 12 inches, sometimes 10 or 14
- Flange repaired or replaced when needed
- New supply line and shutoff, not the old crimped one
- Level set and caulked so it does not rock
Replace the toilet when
- It rocks, or the floor around it is soft
- There is a crack in the tank or bowl
- It needs two flushes to clear
- You have rebuilt the internals more than once
- You want comfort height or a modern low-flow model

What the install includes
- Rough-in measurement from wall to bolt centers before ordering
- Old toilet removed, wax residue cleaned, flange inspected
- Flange repair, extender, or replacement where the height is wrong
