Plumbing fixture replacement in Newmarket.
Toilets, faucets, sinks, shower trim, tub spouts, shut-off valves. Whether you have bought the fixtures or want us to supply them, the same licensed plumbers who build our custom bathrooms install them clean and leak test every one.

Which fixtures can you replace in one visit?
Toilets, faucets, sinks, shower trim, tub spouts, shut-off valves and outdoor taps, usually all in one visit when you send us the list. We confirm each supplied fixture fits the existing rough-in before we come.
Fixture replacement is where a lot of Newmarket homeowners meet us for the first time. A whole bathroom of dated fixtures, a kitchen faucet and sink ahead of new counters, every toilet in the house swapped for low-flow units, or the shower trim updated to match a renovation. Seal Plumbing does it in one visit where we can, and tells you before we start if any fixture you bought will not fit the existing rough-in.
We check what is behind the fixture too. Supply lines, shut-off valves and drain assemblies that are decades old get replaced while we are there, priced separately so you decide. That is the difference between a fixture swap that lasts and one that leaks six months later. Pete and Joseph do the work themselves and leave it clean.
If you are planning the whole bathroom, our bathroom plumbing renovations page covers the rough-in side. For kitchens, see Newmarket kitchen plumbing.

What does plumbing fixture replacement cost in Newmarket?
Fixture replacement in Newmarket is quoted in writing from your list, before any work starts. The price depends on how many fixtures, which types, and whether the supply lines and shut-offs behind them should be replaced at the same time.
Every job is quoted before work starts, in writing for anything beyond a small repair, and the quote is the number that counts. Same-day quotes on most small jobs; larger projects within 24 to 48 hours of a site visit.
