Seal Plumbing plumber installing bathroom plumbing in a Whitby family home

Family-suburb plumbing, done properly.

Whitby is Durham's family heartland — established neighbourhoods like Pringle Creek and Blue Grass Meadows, the heritage streets of downtown and Port Whitby, and Brooklin's fast-growing new phases north of the 407. Growing households drive the work: basements becoming bedrooms and rec rooms, single bathrooms becoming two, and kitchens opening up to fit real family life.

Seal Plumbing is Pete and Joseph, two licensed plumbers who do the work personally. Written quote before we start, tidy site while we're there, and rough-ins planned so your renovation never stalls on plumbing.

What Whitby homes ask of a plumber

Growing families, new Brooklin builds and heritage downtown homes shape the plumbing work in Whitby.

Basements for growing families

Rec rooms, guest bedrooms and second bathrooms — Whitby basements work hard. We rough in and finish basement bathrooms to Ontario code.

Brooklin's new builds

Brooklin homes come with bare basements and builder-grade baths. We're the first trade into the basement and the right one for the ensuite upgrade.

Heritage homes downtown

Older houses in downtown Whitby and Port Whitby need new bathrooms tied carefully into old systems. We plan those tie-ins before quoting.

Whitby plumbing FAQs

All the time. New-build basement finishes and ensuite upgrades north of Winchester are regular work for us.
Yes. Downtown-area homes often run on one bathroom; we plan the tie-in to the existing stack and drainage so the new one works properly from day one.
