Toto Construction in Garland, CA | Rowan Construction Group
We provide independent Toto service across Garland, and the one thing that makes our work here different is this: we measure the floor before we ever set a fixture. Garland’s 1950s-60s slab-on-grade homes sit on expansive black clay that heaves and settles with every drought and rain cycle, so a Toto toilet installed to spec on an out-of-level slab will rock, leak, and fail inspection. We correct the slab issue first, then install. Call (470) 298-9650 for a free estimate.
Why Garland Residents Choose Us for Toto Service
We have worked on Toto components inside the slab-on-grade homes that define Garland’s mid-century housing stock since 2007. Every remodel that exposes decades-old plumbing forces us to know Toto’s part compatibility and tile-in installation quirks without relying on manufacturer authorization. We are an independent Toto service in Plano and Garland, not a factory-authorized dealer, which means our recommendations are based on what actually holds up in Garland conditions, not what a manufacturer program tells us to push.
Grant Rowan, our owner, trained in construction technology at Los Angeles Trade-Technical College, where coursework covered framing, concrete, and project estimating before he ever swung a hammer on a paying job. That training shows up in how we approach Toto work: document the condition of the substrate, name the fix, put the price in writing before anyone starts. Under Clause 1 of the Haven Standard, the price is written before any work begins. That has been our rule across 4,000-plus projects, and it applies to a toilet replacement the same as it applies to a full bath remodel.
Common Toto Construction Problems We Solve in Garland

- Phantom flushes on Toto Drake II toilets. Garland’s hard water accelerates the hardening of flush valve seals, which causes silent tank-to-bowl leaks that cycle the fill valve. Homeowners notice the water bill first. We replace the 3″ flush valve and tower canister assembly with OEM Toto parts, then check the supply pressure to rule out a repeat in six months.
- Sticking fill valves on Toto Ultramax II models after drought cycles. When Garland’s clay soil dries out and shrinks, homes shift, but the real culprit is often sediment from the city’s water supply lodging in the fill valve diaphragm. The valve sticks open, the tank overflows down the standpipe, and water migrates toward the slab. We disassemble, clean or replace, and verify the tank level stops at the factory mark.
- Cracked mounting blocks on Aquia IV skirted bowls. The skirted design hides the mounting block, so a crack from floor racking goes unnoticed until a slow leak appears at the base. We see this most often in older south-side bathrooms where the slab has moved half an inch or more. We pull the bowl, inspect the flange and floor slope, and tell you honestly whether repair or replacement makes sense.
- Split tank-to-bowl gaskets on Toto Promenade toilets in out-of-level baths. A 1950s slab that is out of level compresses the gasket unevenly, and eventually it splits. The fixture drips onto subfloors already stressed by decades of clay-soil movement. We level the tank-to-bowl connection and replace the gasket with the correct OEM part, not a universal fit.
- Flange failures under 1960s-era fixtures. Original cast-iron flanges rust through, and once a Toto is removed for any reason, the old flange often cannot be re-used. We replace the closet flange, anchor it to the slab, and set the new fixture on a reinforced wax ring rated for the gap we actually measured.

AfterToto Service in Garland: What Local Conditions Mean for Your Equipment
Garland’s central and south-side neighborhoods have the highest density of unreinforced 1950s slab foundations in Dallas County. When a new Toto skirted toilet is being installed, our plumbers routinely measure floor slope first, because a spec-perfect Toto install on a half-inch out-of-level slab will rock, leak between the wax ring and flange, and fail inspection in a way Mesquite or Richardson jobs rarely trigger. That is not a line from a training manual. It is what we document on Dallas Toto service calls in Garland every month.
On a kitchen-to-bath addition in the Club Hill neighborhood near Garland Fence Installation territory, our crew demoed a 1962 bath to find the original cast-iron flange had rusted through and the slab had dropped 5/8 inch at the wall. We leveled the toilet footprint with a repair mortar bed, set a new closet flange, and installed a Toto Drake II with an extra-thick reinforced wax ring, then tied the shower pan drain into the same corrected slope so the frameless glass enclosure would not bind. A contractor who does not work Garland slabs every week would have bolted the toilet down and called it done. The leak would have shown up after the first heavy spring rain.
We stock the commonly needed Toto service parts, including 3″ flush valves, tower canister assemblies, fill valves, and tank-to-bowl gasket sets, so most Garland service calls get resolved on the first visit. We default to OEM Toto parts for function-critical components, and use quality aftermarket only for cosmetic items or discontinued trim. On any Toto fixture older than 15 years with slab-related cracking, we will advise replacement with a current model rather than a patch that will fail again when the foundation moves. The advice is free, and the written quote includes the honest numbers either way.
Toto Models & Products We Service in Garland

Our crews service the full lineup of Toto residential fixtures installed across Garland: Drake II two-piece toilets, Ultramax II one-piece units, Aquia IV dual-flush skirted bowls, and Promenade models with Sanagloss glaze. The Sanagloss finish matters in Garland, because the city’s hard water leaves mineral deposits that cling to untreated porcelain. When we spec a replacement, we explain what each model does differently, then put the price in writing.
We also handle Toto shower valves, tub fillers, and the rough-in adjustments that come up during Toto sales & service calls. If the fixture is beyond economical repair, we will tell you, and our full bathroom remodeling, walk-in shower, and tub-to-shower conversion services pick up from there.

Toto Service Pricing in Garland
Here are the line-item ranges we quote for Toto work in Garland. These are flat written prices, not hourly estimates that balloon after the job starts.
| Service | Price Range |
|---|---|
| Full Bathroom Remodeling with Toto fixture replacement | $9,000 - $28,000 |
| Walk-In Shower Installation with Toto shower valve | $4,500 - $12,000 |

What drives the cost? Floor condition is the biggest variable. A Toto replacement on a level slab is straightforward. A Toto replacement on a 1950s Garland slab that has dropped 5/8 inch at the wall requires mortar bed correction before the fixture is set. Age of the existing plumbing matters too: a rusted flange or corroded supply stop adds labor and parts. A free estimate includes the measurement of floor slope, the condition of the flange, and a written price before any work starts. Call (470) 298-9650 to schedule one.

FAQs - Toto Construction in Garland
The flush valve seal has hardened from Garland’s hard water and is leaking tank water into the bowl, which triggers phantom flushes. We replace the flush valve and canister assembly with an OEM Toto part, then verify the water level and supply pressure. Call (470) 298-9650 for a free estimate on the repair.
Yes, but only after we level the footprint. A skirted Toto installed on an out-of-level slab will rock and leak between the wax ring and flange. We measure the slope, build a repair mortar bed where needed, and only then set the fixture. This is standard practice for our Garland slab homes.
Unlikely. Clay soil movement shifts the fixture, but a fill valve that never shuts off is almost always sediment from Garland’s water supply lodged in the valve diaphragm. We inspect, clean or replace the fill valve, and check that the tank water level matches the factory mark.
We default to OEM Toto parts for function-critical components like the 3″ flush valve, tower canister flush assembly, and fill valve. Aftermarket only enters the picture for cosmetic trim or discontinued finishes, and we will tell you before we use it. We are an independent provider, not manufacturer-authorized, so we stock by what works, not by what a program dictates.
Spring rains rehydrate Garland’s clay soil and the slab heaves, which changes the angle between tank and bowl. The gasket compresses unevenly, then splits. We replace the gasket with the OEM part and, if the slab has moved enough to repeat the problem, we will level the fixture footprint so it does not happen again.
