Lewiston bathroom remodels span 1880s triple-deckers with cast iron stacks and lead toilet bends, 1950s ranches with copper supply and below-tile flanges, and recent PEX builds. We plumb to your specific fixture selection — drain centerline measured for the toilet you bought, supply rough-ins set for your vanity, valve framing built for your trim kit. Inspector-ready before drywall closes.

Repositioning sinks to islands or peninsulas is the common Lewiston kitchen scope. In triple-deckers we coordinate with downstairs units because new drain runs pass through their ceiling. We route dedicated branches for dishwasher, refrigerator, disposal, and any pot filler, all leak-tested before close-up.

Lewiston’s gas service through Unitil reaches much of the core, so the heater mix here leans heavier gas than most of our coastal coverage. We install electric tank, heat-pump hybrid, gas tank, and propane tankless. The key install consideration in 1900s triple-deckers is venting — a shared chimney is not a tankless candidate without a re-vent, and we quote the concentric or twin-pipe run before accepting the work.

Lewiston water comes from Lake Auburn — moderately soft to moderately hard depending on season, gentle on tankless heat exchangers. We descale every 18–24 months, replace inlet screens, verify gas pressure under load, and inspect vent slope.

This is one of the most common Lewiston jobs we run. Tree Streets and Little Canada housing — 1880s–1920s wood-frame triple-deckers, brick tenements, corner storefronts — was built with galvanized supply that has been mineral-closing for a century. Symptoms are universal: brown first-draw water, kitchen pressure that drops the moment any other fixture runs, upstairs showers that go cold fast.

A repipe in a Lewiston triple-decker typically runs three to four days because we work through multiple units, coordinating access with tenants and owners. We run new PEX or copper from the meter to every fixture in every unit, abandon the old galvanized in place rather than tearing plaster needlessly, and re-tie venting to current code where we have access. Quoted before we start. No open-ended billing.

Tree Streets and downtown Lewiston laterals are routinely 1900s clay or early cast iron, with mature trees doing the same century-long root-intrusion work we see in every old village. We snake first, camera when warranted, and show you the footage before recommending a spot repair or full lateral replacement. Wastewater flows to LACWA — the joint Lewiston-Auburn Clean Water Authority — and we coordinate permits with the City Water & Sewer Division for any new lateral work.

Same-visit replacements when parts are available. Moen, Delta, Kohler cartridges on the truck.

Triple-decker toilet swaps regularly involve lead bends, sub-floor flanges, and crystallized brass shutoffs — we quote that real scope up front rather than discovering it once the old toilet is off. Newer construction is straightforward.

Frost line in Lewiston runs interior-Maine deep. Frost-free bibbs with the shutoff inside the heated envelope are mandatory. Burst-bibb calls in late March are our most common late-winter visit.

The Androscoggin and its tributaries shape Lewiston’s groundwater. Tree Streets basements and Little Canada cellars see seasonal water. We install primary sumps with battery backup and route discharge so it doesn’t loop back to the foundation.

A.T does licensed gas line work for natural gas (Unitil’s service area covers much of central Lewiston) and propane (the outer rings). Extending gas to a new range, sizing for a generator or tankless retrofit, full manometer leak-test before we leave.
