Get us on site faster

A few details upfront helps us bring the right parts, plan access, and cut downtime.


What is affected

Tell us what is not working: one fixture, one washroom, one unit, or the whole building. Mention any floor drains backing up or multiple slow drains.


Where is the shutoff

If safe, locate the closest shutoff (fixture valve, washroom isolation, or building main). If you cannot find it, we will handle it on arrival.


Any active water or damage

Let us know if water is spreading, dripping through ceilings, or near electrical rooms. If water is actively flowing, contain it and call right away.


Access and timing

Confirm who can grant access, where to park, and if there are locked mechanical rooms or after hours entry steps.


Photos help

If you can, take a quick photo of the fixture, the leak area, or the floor drain. It helps us prep parts and tools before we arrive.


Safety note

If you smell gas or suspect a gas issue, leave the area and call your gas utility from a safe location, then call us to coordinate next steps.

Yes. We can coordinate with property managers, supers, and tenants, and we document what we found and what was completed so your maintenance records stay clean.

Often, yes. If your space is customer facing or you cannot shut down during business hours, ask for after hours options and we will confirm availability.

We diagnose first, then provide a written scope and clear options before work starts. Pricing depends on access, urgency, and what we find on site, but you will know the plan before we proceed.

The fastest dispatch happens when we have the site address, access instructions, a contact on site, and a quick description of the issue. Photos of the area or equipment help us bring the right parts the first time.

If only one sink or one toilet is affected, it is often a local blockage or a fixture issue. If multiple fixtures are slow, gurgling, or a floor drain is rising, that usually points to a main drain restriction.

We generally recommend avoiding them. They can damage older piping, create fumes in enclosed areas, and make the line harder and more dangerous to service.

Yes. Camera inspections are a smart next step when clogs keep returning, multiple drains are affected, or you want to confirm the condition of the line before spending more on repeat clearing.
