Topsham bathroom remodels span a wide era range. An 1880s home near the bridge or along Elm Street brings cast iron stacks, lead bends, original galvanized in the wall a hundred-some years. A 1960s split-level off Foreside Road is mid-century work — copper supply, single 4-inch cast iron stack, vanity setbacks that don’t accommodate modern double-sink layouts without re-piping. A 2010s subdivision build is straightforward PEX rough-in. Each scope gets a written, fixed quote before we start. Inspector-ready before drywall closes.

Topsham kitchens frequently rebuild around an island or a peninsula — both popular in the mid-century and newer housing stock here. We route new drain and supply, re-vent the new location, and run dedicated branches for dishwasher, refrigerator, disposal, and any pot-filler or instant-hot tap.

The Topsham heater split skews electric tank in postwar housing with a growing share of heat-pump hybrid in newer or recently renovated builds. Natural gas service is limited — Unitil reaches some bridge-adjacent blocks, not most of town — so propane tank and propane tankless cover most gas-fired installs. We size to actual usage, verify breaker and pan on electric installs, and quote venting carefully on tankless retrofits. Brunswick & Topsham water is moderately soft from groundwater — tankless heat exchangers do well here with descale every 18–24 months.

Topsham Village and the older blocks near the bridge have housing back to the 1800s, much of it plumbed originally with galvanized supply that’s been mineral-closing for a century. Kitchen pressure thins the moment any other fixture runs, first-draw water comes brown, upstairs shower stays warm half as long as it used to. Full repipe to PEX or copper through the most accessible path, old galvanized left in the walls rather than tearing plaster unnecessarily, entire run pressure-tested before close-up.

Older Topsham Village laterals are clay or early cast iron, with mature trees along Elm and Main doing the same root-intrusion work mature trees do in every older village. Snake first, camera if warranted, repair what’s actually broken. A good portion of Topsham outside the village core is on private septic rather than town sewer. We clear lateral lines to the tank; tank pumping and leach-field rebuilds belong to other trades.

Inland Topsham — Foreside Road past the village, back roads toward the Bowdoinham line, larger-lot residential along the Cathance — is heavily private well territory. Submersibles 100–300 feet down, pressure tanks in basements, pressure switches that wear out. Pump pulls, tank changeouts, switch replacements, drop-pipe rewiring all in scope. We don’t drill new wells.

Same-visit replacements when parts are on the truck — Moen, Delta, Kohler cartridges and trim standard. Pre-1900 Topsham Village toilet installs sit on lead bends and original brass shutoffs more often than not — actual swap scope usually exceeds what looks like a thirty-minute job, and we quote that real scope before starting. Mid-century and newer homes are straightforward.

The Cathance River and its tributaries shape groundwater across Topsham. Houses along Pleasant Hill, lower-elevation lots near the river, and the Cathance-side residential see seasonal water in heavy spring rains. Primary sumps with battery backup, discharge routed where the next storm can’t loop the water back to the foundation.

Topsham sits inland enough that frost runs interior-Maine deep across the whole town — frost-free bibbs are mandatory. We replace failing bibbs with frost-free designs, re-pipe runs inside the conditioned envelope where the previous install cut corners, pressure-test before closing. Topsham gas work is mostly propane: licensed propane line work for new ranges, dryers, generator feeds, tankless retrofits, manometer leak-tested. The pockets of Unitil natural gas service get the same treatment.
