Common questions
Contact and service questions
What to send, what happens next, and when a site review may be needed.
How can I contact Water Doctor?
Call +1 289-748-9666, email info@waterdoctor.ca, or use the form on this page. The Denison showroom is open Monday through Friday from 10:00 AM to 5:00 PM. Current addresses and hours for both Markham showrooms are listed on the Locations page.
What should I include in my message?
Include your city, whether the request is residential or commercial, the water issue, the existing system or model when applicable, and the best way to reach you. Photos, recent water data, flow requirements, or error details can be discussed during follow-up.
How quickly will I receive a recommendation or quote?
Response and quoting time depends on the information available and the project scope. Some product questions can be answered from the initial details; sizing, installation, commercial, well-water, or controls work may need additional measurements or a site review before a recommendation or quote is confirmed.
Can I visit a showroom?
Yes. Water Doctor has two Markham showrooms. Check the Locations page for the current address and posted hours, and call ahead when you want a specific product or specialist to be available.
Can the first discussion happen by phone or email?
Yes. The first discussion can clarify the issue and identify what information is still needed. An on-site assessment, water test, or technical review is recommended only when the treatment, sizing, installation, or project scope cannot be confirmed remotely.
What should I do about an urgent service issue?
Call +1 289-748-9666 during business hours and describe the system, symptoms, error messages, and any loss of water service. Availability and response timing are confirmed for the specific request; the website does not promise 24-hour emergency coverage.
