Looking at toilet replacement in Richmond 77406? That’s around 12 miles from us, well inside the area we work daily.

Almost every house in this metro sits on a concrete slab, which means the closet flange under your toilet is anchored in concrete rather than screwed to a wooden subfloor. That single fact changes what goes wrong. You are far less likely to find rotted framing under a leaking toilet and far more likely to find a corroded cast iron flange, a flange sitting below a floor that has been tiled over twice, or a lead bend from the original construction. Those conditions are concentrated in inner-Houston housing from the 1950s through the 1970s, while newer Katy and Cypress homes bring their own smaller set of issues.

What the work involves

In an older home the inspection is the job. Once the toilet is off, we look at the flange material and condition. Cast iron flanges corrode where they meet damp concrete, and the bolt ears break away, which is why the toilet rocked. Some homes of that era have lead closet bends, which are serviceable but require care and specific repair methods rather than aggressive cutting.

Depending on what we find, the repair is a stainless repair ring over sound cast iron, a full flange replacement, or in the worst cases a section of drain repair, which in a slab means concrete work.

Flange height gets checked against the finished floor. Bathrooms that have been retiled, sometimes over existing tile, often have flanges sitting well below where they should be, corrected with an extender rather than stacked wax.

In newer homes the flange is usually PVC and sound. The typical findings there are a stop that will not reseal, a flange loosened from the slab, or a fixture that was never shimmed and has been rocking since the builder set it.

Both end the same way: sound flange, fresh seal, level fixture, tested.

Building for Gulf Coast conditions

Slab-on-grade over expansive clay adds a second layer to this. Houston soils swell and shrink, and slabs move over decades. That movement shows up in bathrooms as cracked tile, doors that bind, and occasionally a flange that has shifted relative to the drain below. It is also why so many bathrooms in this metro have been retiled, which brings us back to flange height.

Cast iron waste lines under those slabs are the bigger long-term issue in 1950s through 1970s housing. Where a toilet has been leaking at the base for a long time, or where drainage is slow throughout the house, the pipe below deserves a camera inspection rather than a guess. Finding it during a toilet replacement is far better than finding it during a full remodel.

Humidity contributes the most common false alarm. Tank condensation in a Houston summer produces a puddle at the base that looks exactly like a failed seal. Before anyone tears into a floor, the simple test is drying everything thoroughly and watching when and where water returns.

Working in Richmond

Richmond is the Fort Bend County seat, and a Richmond address covers two very different building situations. Near the historic core there are genuinely old homes — late-1800s and early-1900s wood-frame on pier-and-beam — where the work starts underneath: sill plates, joists, subfloor, leveling, and usually a full rethink of electrical and plumbing before anything gets finished. Properties in a historic district can carry additional review. Then there is everything built under a Richmond address since the 2000s: subdivisions west and north of town on post-tension slabs, where the structure is sound and the ask is a better kitchen, a real primary shower, or opening up a closed plan. Those two are different crews and different budgets. What they share is the ground — expansive clay that moves seasonally, which reaches a pier-and-beam house through its piers and a slab house through the slab itself. Permitting depends on city limits versus unincorporated county.

What drives the cost

Age drives everything here. A newer home with a sound PVC flange is a straightforward replacement. An older home may need a repair ring, a full flange replacement, height correction, and a new supply stop, and each is a real line item.

Cast iron adds labor over PVC on any repair, because cutting and fitting it is slower.

If the drain itself below the flange is compromised, the job moves into slab work, which is a different scale involving concrete cutting, plumbing, backfill, and floor repair. It is uncommon on a simple replacement but it does happen, and it is why we inspect rather than promise.

Floor repair matters where the old fixture footprint was larger and the new one exposes unfinished tile or an old cut.

Fixture selection spans a wide range independently of any of this.

And if several toilets in a house are the same age, doing them together saves on visits.

How we work

We measure the rough-in and look at the existing fixture before recommending anything. Once the old unit is off, the flange inspection determines the rest, and we show you what we find with a photo rather than describing it.

Any repair is priced and explained before it is performed. Nobody wants to hear about a flange replacement after the fact.

Then: corrective work, fresh seal, set and level the fixture with shims where the floor demands it, replace the stop and supply if warranted, connect, and test through multiple cycles while checking the base, tank bolts, and connection.

We haul the old fixture off and clean the area.

Common questions

What causes a sewer smell around the toilet?

Usually a failed seal at the flange letting gas escape at the base, or a dry trap in a nearby fixture that is rarely used. Occasionally it is a vent problem. It is worth diagnosing rather than masking, because a leaking base seal in a slab home also means water going somewhere it should not, quietly, for as long as it takes to notice.

Is a builder-installed toilet in a newer home worth replacing?

If it functions well, not urgently. Builder-grade units are typically serviceable and simply basic. People replace them for comfort height, better flush performance, easier cleaning, or a bidet seat. If the existing one rocks, runs constantly, or requires two flushes, that is worth addressing either way, and sometimes the fix is a repair rather than replacement.

My house is from 1965. What will you likely find under the toilet?

Most often a cast iron flange with corroded bolt ears, sometimes a lead closet bend, and frequently a flange sitting low relative to a floor that has been tiled at some point. None of that is alarming and all of it has established repairs. What matters is that it gets corrected rather than covered with extra wax rings, which is the shortcut that leads to leaks.

Do I have to worry about the drain line under the slab?

Not on every toilet replacement, but it is worth thinking about in a home from the 1950s through the 1970s. Those houses often have cast iron under the slab, and decades of use plus soil movement produce scaling, cracks, and low spots. If drainage is slow throughout the house or a leak has persisted, a camera inspection answers the question directly.
