What to do if water is flooding the building right now
Act on what you can do safely, and do not go into standing water near live electrical equipment.
While you wait for the plumber
- Shut the water:Close the nearest fixture shutoff, or the building main if you know where it is. Tell staff or the property manager where it is for next time.
- Stop using drains:Restrooms, mop sinks and kitchens share lines. One flush can push sewage out of a floor drain.
- Keep power away from water:Do not touch outlets, panels or equipment in wet areas. Shut power at the breaker only if you can reach it dry.
- Gas smell:Leave the building, use no switches or phones inside, and call Nicor Gas at 800-942-9727 or 911 from outside.
- Move people and stock:Clear the area, lift product off the floor and put out wet floor signs.
- Take photos:Photograph the water and the damage before cleanup for your insurer and your landlord.
Then call the 24/7 line. Say if it is a restaurant, an office, a retail unit or a unit in a larger building, since that changes who needs to be told.
Urgent commercial problems we are called for
These situations most often turn into same-day or after-hours calls.
Active leak with a source you cannot find
Some callers have narrowed a leak to within a few feet but need equipment to pinpoint it. Leak detection tools locate pipes behind finish materials before anyone cuts.
Floor drain overflow
Water coming up through a floor drain or a grate that must be lifted right away often means a blocked line downstream. Drain cleaning and a camera trace the cause.
Grease trap and kitchen lines
Restaurants and food prep spaces ask about grease trap pumping and kitchen drain backups. Pump-out scope depends on the trap type, so ask the dispatcher whether it fits.
Backflow and water shutoffs
A missed annual test can lead the water provider to lock valves. The plumber confirms the device, the test requirement and the paperwork path.
Sewer backup into the building
A building main that is blocked or damaged can send sewage into the lowest drains. See sewer line repair for the longer fix after the flow is restored.
What to expect on a commercial job
Commercial work usually starts with access. Someone has to let the plumber in, show the shutoffs and confirm who can approve the work. If you are a tenant, the landlord or property manager often controls the building main, the mechanical rooms and the roof, so call them at the same time as the plumber.
After-hours visits are common because many businesses cannot shut down during the day. Tell the dispatcher what time the space is empty, whether alarms or keys are involved and who will be present. Property managers handling several units should have a short list of shutoff locations and contacts ready, since that is what saves time at 11 at night.
Some jobs have to be done in stages. A temporary stop of the leak may come first, with the permanent repair planned once the space is safe and dry. Expect the plumber to explain what is a stopgap and what is final, and to give you the price before work starts.
One honest note: we do not always have the right equipment for every commercial specialty, and some large kitchen or industrial jobs go to a specialist. The dispatcher tells you early rather than after a wasted trip.
Who usually needs to be involved
Clear roles speed up the first hour of a commercial call.
| Situation | Who to tell | Why |
|---|---|---|
| Tenant in a multi-unit building | Property manager or landlord | Controls the main shutoff and shared lines |
| Water bill spike or notice of a leak | Water department and the plumber | The village owns the meter, the owner owns the line past it |
| Backup into the building | Building owner | The sewer service line to the main is the owner's |
| Restaurant or food business | Manager on duty | Grease and kitchen drains need a different scope |
| Gas smell | Nicor Gas and 911 | Leave first, then call |
In Buffalo Grove the village owns the water mains and meter, and the property owner owns the service line on the private side.

What drives commercial plumbing pricing
The price is explained before work starts. After-hours work is one of several factors.
Permits, contractors and the village
Buffalo Grove requires a permit for plumbing work other than maintenance, servicing or repairs, and contractors must be registered with the village. The Community Development office is at 847-459-2530.
Sewer or water service repairs can be handled on an emergency basis, with the permit applied for within 24 hours and an underground inspection after 48 hours' notice. Call 811 before digging, at least 3 days ahead through JULIE.
Planned commercial work and nearby towns
Not every commercial call is an emergency. Fixture upgrades, restroom remodels, new installations and pipe replacement are better scheduled around business hours.
Our dispatch covers Wheeling, Arlington Heights, Lincolnshire and Deerfield. See the service area, the full list of services or contact details.
Where the facts and rules come from
Permit and ownership details come from the Village of Buffalo Grove Community Development and Public Works pages. Gas guidance follows Nicor Gas, and digging rules follow JULIE (811).
Illinois plumbers are licensed by the Illinois Department of Public Health under the Illinois Plumbing Code. You can check a plumber's license on the IDPH online verification page before the work begins.
Commercial work falls under the same Illinois Plumbing Code and licensing standards as homes, with the village deciding which permits a given building needs.
Questions we hear from homeowners
Yes. The line is answered around the clock, including nights, weekends and holidays. Tell the dispatcher it is a commercial space and whether anyone is on site.
Close the nearest shutoff if you can, stop using drains and call the property manager as well as the plumber. The landlord often controls the main.
Yes, with leak location equipment that traces pipes before walls or floors are opened. Some leaks need staged work.
Ask the dispatcher about your trap type. Some pump-out and kitchen drain work is routed to a specialist.
It means usage looks unusual. A plumber checks the line past the meter, fixtures and irrigation.
