/ HelpCommon Questions

How do I choose a reliable plumber in Oshawa?+

Start with the rating — look for a plumber holding 4.5 stars or higher with a healthy number of recent reviews, which signals consistent, current service. Confirm they're properly licensed and insured for the work you need, and read a few reviews to see how they handle problems, not just praise. The listings below are sorted by Google rating to make this easier.

What's the typical cost of a plumber in Oshawa?+

Pricing varies widely by the scope of the job, materials, and how urgent the work is, so there's no single rate. The most reliable approach is to contact two or three plumbers directly for a quote on your specific situation. Use the "View on Google Maps" or "Visit Website" buttons on each listing to reach out.

Are these plumbers verified?+

Yes. Every listing is sourced from public Google Business Profile data — business name, rating, and review count — and refreshed monthly so closed or relocated businesses drop off. We show only what's already public; we don't add or alter business details.

How can I contact a plumber?+

Click "View on Google Maps" to get directions, hours, and the business's public contact options, or "Visit Website" to reach them online. We don't publish private phone numbers or email addresses here — the business's own Google profile and website are the right place to get in touch.

I'm a business owner — how do I update or remove my listing?+

Email support@publicleads.com with the subject "Removal Request" and include your business name and city. We process removal and correction requests within 48 hours.
