Toto Construction in Selma, TX | Mason Remodeling Co San Antonio
We provide independent Toto service across Selma, from fixture installation during full remodels to repair work on existing units, as our General Contractor in Selma handles every phase. Selma homeowners call us most often for Toto work tied to slab movement and hard water, two conditions that shape how these fixtures behave in this part of the Northeast San Antonio development belt. Our crew has rebuilt and retrofitted Toto fixtures across hundreds of Selma remodels, and we’re one call away at (254) 269-5071.
Why Selma Residents Choose Us for Toto Service
We know Toto fixtures, including the Drake, Aquia, Nexus, and Promenade lines, and we know how each one behaves in Selma’s specific conditions. Isaac Pruett, owner at Mason Remodeling Co San Antonio, learned construction fundamentals at Los Angeles Trade-Technical College before spending two decades on projects across the Southwest, and he brings that experience to every Toto job we take on in Selma. We stock OEM-compatible parts for fast local turnaround, and we’re an independent Toto service provider, not manufacturer-affiliated or authorized, which means our recommendations are driven by what actually works on your fixture, not by a corporate parts mandate. Our Toto sales & service work covers everything from new installations to retrofits in existing production homes.

Common Toto Construction Problems We Solve in Selma
- Sticking dual-flush valves on Aquia models. Selma’s hard water leaves mineral deposits that seize the flush valve if the fixture isn’t descaled annually. The result is intermittent flushes or a toilet that runs constantly, and the fix is usually an OEM flush valve replacement combined with resetting the bowl on a new wax ring.
- Corroded supply line fittings on Drake and Promenade models. Homes built during the late 90s and early 2000s in Selma often have fittings that have corroded where slab settling has shifted the toilet flange. We replace the supply line and check the flange height before resetting the bowl.
- Cracked one-piece Nexus bowls. The clay-rich soils in parts of Selma, especially near Cibolo Creek, swell and shrink enough to flex a slab under a one-piece Toto. A hairline crack at the tank-to-bowl seam usually means replacement, not repair.
- Weak flushes from Tornado flush-rim buildup. Homes on the outskirts of Selma that draw well water with high iron content develop mineral scale inside the rim jets. That reduces swirl pressure and leaves waste behind. We descale the rim and verify flush performance before calling the job done.
- Flange tilts from slab settlement. Many Selma production homes are still settling, and a tilted flange breaks the seal and lets water seep under the bowl. We reset on a jumbo wax ring and correct the rough-in so the fixture sits level and seals tight.
Toto Service in Selma: What Local Conditions Mean for Your Equipment
Selma sits on the Blackland Prairie’s expansive clay, including older homes near the Cibolo Creek floodplain, where differential settling is common. That clay shrinks and swells enough to shift toilet flanges and crack one-piece Toto bowls in homes west of I-35, a problem you won’t see across the county line in New Braunfels’ limestone. At a tract home off Old Austin Road, our tech found a Toto Aquia that ran constantly because the dual-flush valve had seized from mineral scale. The slab had settled enough to tilt the flange 3/16″, so we reset the toilet on a jumbo wax ring, installed a new OEM flush valve, and the bowl sealed tight. The customer hasn’t had a running toilet since. That’s the difference between generic toilet advice and what we handle in Selma every week.
Toto Models & Products We Service in Selma
We work on the Toto Drake with its G-Max flush tower series, the dual-flush skirted Aquia, the one-piece Nexus high-efficiency line, and the classic two-piece Promenade. We install genuine Toto OEM fill valves, flush towers, and seals so the repair holds up, and we use quality aftermarket supply lines and wax rings when the OEM part is backordered or overpriced. Our shop keeps common parts on hand for fast Selma turnaround, so you’re not waiting on a special order for a routine repair. We rarely recommend repairing a severely cracked one-piece Toto, replacement is usually safer and more cost-effective on a settling slab.

FAQs – Toto Construction in Selma
The dual-flush valve on the Aquia seizes up from mineral scale in Selma’s hard water, so jiggling the button doesn’t clear the buildup that has formed inside the valve seat. The seal can’t close fully, so water keeps passing into the bowl, and the fix is an OEM flush valve replacement. Call (254) 269-5071 for an exact quote, estimates are free.
Yes, and we see it regularly in homes west of I-35 where the Blackland Prairie clay expands and contracts under the slab. A Nexus or other one-piece Toto is vulnerable at the tank-to-bowl seam when the slab flexes, and once that seam cracks, the fixture needs replacement, not a patch. Call (254) 269-5071 and we’ll inspect your slab and your fixture.
Yes, we handle wall-hung Toto installations in older Selma homes as part of our Bathroom Remodeling in Selma, and we adjust the rough-in to account for out-of-level slabs and existing plumbing locations. The cost typically falls within our bathroom remodel range of $9000 – $28000 depending on how much structural work is involved. Call (254) 269-5071 to discuss your project and get a written estimate.
The most common is a sticking Aquia dual-flush valve caused by hard water scale, usually on fixtures that haven’t been descaled in years. It presents as a toilet that runs intermittently or flushes weakly, and we fix it with a new OEM valve and a proper bowl reset on homes where slab settlement has shifted the flange. Call (254) 269-5071 for a free in-home assessment.
We stock common OEM parts for the Drake, Aquia, Nexus, and Promenade lines, including flush towers, fill valves, and seals, so most Selma repairs happen same visit.
