Sump pump installation in Newmarket.
A new sump pump sized for the water your basement actually gets, with the pit, discharge and check valve set properly. Plus sewage ejector systems for basement bathrooms. Licensed plumbers, written quotes.

Do I need a sump pump in Newmarket?
If your basement gets water in the spring thaw or after storms, or you are finishing a basement on the low ground along the Holland River in Newmarket, yes. We install the pit, pump, discharge and check valve, and add a sewage ejector where a basement bathroom sits below the main drain.
The older streets of Newmarket near Fairy Lake and the Holland River sit low, and the spring thaw and summer storms put real water into the weeping tiles across town. A sump pump is what keeps that water out of the basement. Seal Plumbing installs new sump systems in homes that never had one and replaces undersized or worn pumps, setting the pit, the discharge line and the check valve so the pump cycles properly and the water goes where it should.
If you are finishing a basement, the sump pump is only half the story. A basement bathroom below the main drain needs a sewage ejector system to lift waste water up to the sewer line. We install the ejector basin, the pump, the vent and the check valve as part of the full basement plumbing rough-in, built to the Ontario Plumbing Code and inspection ready.
Pete and Joseph do the work themselves and quote it in writing first. If your basement is wet and you are not sure a pump is the answer, our weeping tile and wet basement guide is a good place to start.

What does sump pump installation cost in Newmarket?
Sump pump installation in Newmarket is quoted in writing after seeing the basement, typically within 24 to 48 hours. The price depends on whether a pit exists, how far the discharge has to run, the pump size the water load needs and whether an ejector system is part of the job.
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.
