Toto Construction in Irving, TX | Penhallow Remodeling Dallas
We’re Penhallow Remodeling Dallas, and we provide independent Toto service across Irving without any manufacturer affiliation. The Toto work we do here is different because Irving’s 1960s-1990s slab-on-grade homes put real stress on Toto fixtures in ways new construction never does: cast-iron waste lines corrode from the inside, clay soil shifts under slabs, and hard water attacks flush valves year-round. If your Toto Drake II runs long after you flush it, or your skirted Promenade won’t seat right after a remodel, call (940) 204-5368. Trevor Nash leads our crew, and he’ll give you a number before we pick up a tool.
Why Irving Residents Choose Us for Toto Service

The biggest reason? We’ve spent years inside Irving’s slab homes and low-rise apartments, pulling Toto toilets off corroded cast-iron flanges in the Hospital District and resetting them in Del Rancho ranches where the slab has moved enough to oval the flange. Trevor grew up in Los Angeles, trained at Los Angeles Trade-Technical College, and spent years on foundation repairs and full kitchen gut-outs before serving the Dallas area. So when we tell you a Toto fixture needs a repair ring or a new fill valve, that’s coming from someone who’s done this work on a hundred slabs just like yours.
We’re not a Toto dealer, and we don’t pretend to be. We’re an independent general contractor that installs and services Toto fixtures as part of bathroom remodels, and our Toto sales & service work covers everything from a simple fill valve swap to a full gut. We use genuine Toto OEM parts for flush and seal components, we show up in uniform, and we’re background-checked. A live person answers our phone 24/7, and the written price we give you before work starts is the price on the invoice.

Common Toto Construction Problems We Solve in Irving
- Phantom refills on Drake and Ultramax models. Irving’s hard water and high summer humidity degrade flush valve seals faster than you’d expect. The toilet fills, stops, then trickles again ten minutes later. That’s usually a failing flush valve seal, and OEM replacement fixes it.
- Fill valve chatter after slab leaks stir up silt. Original Type A/B fill valves in older Toto models clog with sediment after a slab leak disturbs the water line. You’ll hear chattering or grinding during refill. We swap in a new OEM fill valve and the noise stops.
- Cracked tank-to-bowl gaskets from slab heave. When Irving’s expansive clay soil shifts, it moves wall-mounted carriers and floor-mounted toilets alike. The tank-to-bowl gasket cracks, you get a slow leak behind the bowl, and it’s often mistaken for a supply line problem.
- Diverter and mixing-valve failures in Toto shower trim. Hard water scale builds inside the diverter and mixing valve, so your shower pressure drops or the temperature swings. Homeowners often think they have a leak behind the tile. Most of the time it’s the trim cartridge, not the plumbing.
- Loose or rocking skirted toilets after a remodel. Toto’s skirted Promenade and Vespin II models look clean, but if the subfloor isn’t perfectly level after a remodel on a slab home, the skirt doesn’t seat right and the bowl rocks. We shim and reset properly the first time.
Toto Service in Irving: What Local Conditions Mean for Your Equipment
Here’s what most Toto pages won’t tell you. In Irving’s older neighborhoods like the Hospital District and Del Rancho, we routinely uncover original cast-iron waste lines that have corroded from the inside. The pipe looks fine on the outside, but the interior walls are thin and pitted from fifty years of water chemistry. That internal corrosion causes slab leaks that mimic soil movement damage, and it creates a double diagnosis unique to this city’s 1960s slab homes. When we pull a Toto toilet and see scaling or rust on the closet flange, we now check for both a failed wax ring and a hidden cast-iron crack before we reset the fixture. It’s a small step that keeps us from reinstalling a Toto on a flange that’s about to fail. In a newer home on a post-tension slab in Valley Ranch, that check isn’t as urgent. In a 1968 ranch in Del Rancho, it’s the difference between a repair that lasts and a callback in three months.
Toto Models & Products We Service in Irving
We work on the Toto lines most common in Irving bathrooms. The Drake II with G-max and Tornado Flush, the Ultramax II, the skirted Promenade, and the Vespin II. For flush and seal components, we use genuine Toto OEM parts. Flappers, fill valves, gaskets. These parts preserve the flush performance Toto engineered. We do not cut corners with generic aftermarket seals on a Drake II, because the flush tower tolerances are tight. For shower trim and mixing valves, we’ll use factory cartridges where they matter. When a repair exceeds roughly 45-50% of the cost of a new Toto unit, or when the porcelain is cracked, we’ll recommend replacing the fixture. Patching skirt damage on a Promenade is false economy, and we’ll tell you that plainly.

AfterToto Service Pricing in Irving

Here are the numbers we quote in Irving, and they line up with what our Irving service area pricing reflects across the board.
| Service | Price Range |
|---|---|
| Toto Drake II installation (fixture only) | $400 – $900 |
| Toto fill valve replacement (OEM) | $120 – $250 |
| Wax-free toilet seal replacement | $80 – $180 |
| Full Bathroom Remodel | $9,000 – $28,000 |
What drives the cost up or down in Irving is the condition of the flange and subfloor. If your cast-iron flange is sound, a Drake II install stays at the low end. If we find a cracked flange or a compromised slab repair, that adds flange repair work. Every estimate includes a written line-item breakdown before any work starts. Call (940) 204-5368 for your free estimate, and we’ll put the number in writing.

FAQs – Toto Construction in Irving
Why does my Toto Drake II keep running long after flushing in Irving?
That’s almost always a failing flush valve seal, which breaks down faster in Irving’s hard water than it does in softer-water cities. The rubber seal loses its edge, water slowly leaks from tank to bowl, and the fill valve cycles on to top it off every few minutes. We replace the seal with a genuine Toto OEM part, and usually the fill valve at the same time, since the two wear together. Call (940) 204-5368 and we’ll get you a written price before we start.
Can my existing Toto toilet be reused during a full bathroom remodel on a slab foundation?
Yes, in most cases. We’ve reset dozens of Toto fixtures during Bathroom Remodeling - Irving slab-home projects. The question is the flange and the cast-iron beneath it. If the flange is solid and the waste line isn’t internally corroded, we’ll pull the Toto, set it aside, and reinstall it on a new wax-free seal. If we find a cracked flange or rust scaling, we’ll repair the flange before the fixture goes back.
I heard Toto toilets are hard to install on old cast-iron flanges. Is that true in Irving?
It’s true that Irving’s 1960s cast-iron flanges complicate things. The cast-iron can be pitted, slightly ovaled by slab movement, or the flange slots are too worn to hold closet bolts. We use repair rings and flange spacers to restore a solid mounting surface, then set the Toto on a wax-free seal. It takes more time than a new-construction install, but it’s a routine fix for our crew.
Do you repair Toto shower valves with hard-water damage, or just replace the whole trim?
We repair the valve first. Hard water in Irving builds scale inside the diverter and mixing valve cartridge, and often a new OEM cartridge restores pressure and temperature control. If the trim body itself is cracked or the valve body is seized beyond service, we’ll replace the trim or the whole valve, but we won’t jump to replacement when a $300 cartridge fixes it.
How do you handle a Toto bathtub during a tub-to-shower conversion in an Irving home?
We remove the Toto tub, inspect the subfloor and drain plumbing, and build the shower on a properly sloped pan with a moisture-resistant substrate. In Irving’s slab homes, the old tub drain often runs through the slab, so we check for cast-iron corrosion before we move anything. The conversion typically runs $3,500 – $10,000 depending on tile, glass, and valve choices. Call (940) 204-5368 for an exact quote after we see the bathroom.
