Commercial Floor Drain Installation in the GTA

Water On A Commercial Floor Isn't A Small Problem

It’s a recipe for a fall and a fall accident. It’s inventory damage. In a restaurant kitchen or food processing establishment. Standing water in a basement/ mechanical room leads to corrosion of equipment, and mold conditions develop quickly in the concrete.


None of this occurs if a commercial floor drain is properly installed to move water where it belongs: out of your building.


For more than 20 years BOS Plumbing and Drains has been doing commercial floor drain installation throughout the GTA. We work with rental property managers, contractors, facility supervisors and business owners that want the job done right the first time, with permits obtained and inspections passed.
 

Commercial Floor Drain Systems We Install

There are more than one type of floor drainage for commercial properties. The right solution will depend on the space, the amount of water and the existing plumbing system. 


Here’s what BOS installs:


Standard Commercial Floor Drains:
Round or square floor drains with a floor drain grate, floor drain trap and connection to a building’s floor drain connection. Used in mechanical rooms, utility, bathrooms and areas where service work is conducted. Not actually “sizing for what is available” but “sizing for what is needed.


Trench Drain:
A long linear channel that is used to accommodate large amounts of water into a large drainage surface. Frequently found in restaurant kitchens, car wash, loading docks and manufacturing floors. We shape the channel, level off the slope, place the body in and place the grate in.


Basement Drain Install:
We do basement drain installation in a residence or a basement utility area in a commercial or industrial building and tie the drain in properly to the sanitary or storm sewer system. If not done correctly, a basement sewer backup will cause the basement to flood.


French Drain And Drain Tile Systems:
Water control around the foundation or in the basement. A French drain basement system that collects the water at the footing and directs it away from the slab. Drain tile basement systems are installed with perforated pipe in gravel, both as new construction and in retrofit applications.


Ground Drains And Outside Drainage Areas:
Drainage installations that are located outside of commercial facilities, such as parking surfaces, loading areas, or landscaping areas that must drain water away.


Area Drains:
These are flat or recessed drains that run along paved surfaces, courtyards and commercial patios where water pools and is unable to flow away.

Signs You Need New Commercial Floor Drain Installation 

Not all drainage problems have to be repaired. In some cases, the system may be outmoded, undersized, or even installed badly from the beginning.

Some of the indicators of warning signs are:

  • Water pooling around drains
  • Slow drainage during washdowns
  • Sewer smells coming from floor grates
  • Cracked or rusted drain covers
  • Repeated drain backups
  • Standing water in mechanical rooms
  • Uneven concrete causing poor drainage
  • Flooding during heavy rain

However, if you’re constantly having to call for drain cleaning, it could be the actual drain system and not just the blockage.

How We Install Commercial Floor Drain Systems 

Most homeowners don’t realize all the things that need to be done for a good installation. This is what actually occurs.

Step 1: Site assessment: We assess floor, slope, existing drain lines, connection points and sources of water. We do not begin sawing concrete until we know what we are doing!

Step 2 Sizing and layout: In reality, the size and layout of the drain body must accommodate the amount of water you actually use. A mechanical room’s flow requirement would be different from a commercial kitchen that is hosed down 3 times a day with a trench drain. It’s sized right for us.

Step 3 Concrete cutting and excavation: At the proper location, we cut and open the floor to the depth required for the drain body and trap assembly, inspect the existing drain line for condition and capacity prior to tying in a new drain line.

Step 4 Drain body installation: The body is installed at the right height from the desired finished floor level, so the floor drain grate is neither recessed into the floor nor is it sticking up. Traps are in place and can be cleaned. Added backwater valve as per the Code.

Step 5 Connection to drain line: We connect to the sanitary or storm sewer system using the proper fitting, slope and watertight connections. All joints are made to Ontario Building Code and commercial plumbing standards.

Step 6 Concrete restoration: Concrete is used to fill in the cut area; it is finished to closely match the existing floor; and protected while it cures.

Step 7 Testing and documentation: The drain is tested under flow. A record is provided in writing as to what was installed, where it is connected and what to look for.

Commercial Plumbing Permits & Inspections 

In most municipalities in the GTA a building permit is required for a commercial floor drain installation. We obtain the permit, schedule the inspection and obtain the permit signature. There is no need to go through that process.

If a contractor assures you that you don’t need a permit for your commercial floor drain project, ask for a second opinion. Non-permitted drain work is a liability and an issue when trying to sell or refinance the home.

Commercial Buildings We Commonly Service 

Our commercial plumbing service team does floor drain installations in:

  • Restaurant kitchens and food service facilities
  • Grocery stores and food processing buildings
  • Car washes and auto service shops
  • Manufacturing and industrial facilities
  • Warehouses and distribution centres
  • Commercial laundries
  • Apartment building mechanical rooms
  • Condo utility and parking garage areas
  • Medical and dental clinics
  • Retail plazas and shopping centres
  • Schools, gyms, and recreation facilities
  • Hotels and hospitality properties

If your facility has concrete floors and water that needs somewhere to go, we’ve probably worked in a building just like it.

What Poor Floor Drain Installation Can Cost You 

As time goes on, an improperly installed floor drain is a much more serious issue.

Slope/tube/pipe sizes that are too small, or the wrong drain connection may cause:

  • Slip-and-fall hazards
  • Water damage to inventory or equipment
  • Sewer gas entering the building
  • Concrete deterioration
  • Mould growth
  • Failed inspections
  • Repeated backups during storms
  • Expensive emergency plumbing repairs

Most commercial floor drain failures we repair started with improper installation years earlier.

Common Floor Drain Installation Mistakes 

One of the more frequent plumbing repair calls that we receive is when floor drains are not installed properly. This is what generally goes wrong.

Wrong Slope: A floor drain has to be the low point of the surrounding floor. However, if the concrete around it slopes away from the drain, the water accumulates around it. The floor elevation around the drain has been set properly when installing the drain.

Trap That Dries Out: Sewer gas blocking the floor drain trap requires water to do so. When the trap is used in rarely used areas, it evaporates. Trap primers are placed in mechanical rooms and other areas that do not experience much usage to keep the traps wet automatically.

Drain Body Set Too High Or Too Low: A grate that is higher or lower than the floor height is a trip hazard. One that is too low will form a low area where dirt can build up and be difficult to clean. We set it flush.

Wrong Connection: A sanitary drain connected to a storm drain (or vice versa) is a line of code and has consequences. A verification of the connection point is done prior to tying-in.

No Backwater Valve: If you have a floor drain in an area that is susceptible to sewer backups without a backwater valve, then this floor drain is where sewer backup will enter your building. We instigate them, where and when they are needed, and where they are sensible.

What A Commercial Drain Installation Typically Costs 

This is a question we are asked frequently. There are some fundamental differences between installing a basic floor drain in an accessible, concrete floor slab, and performing a trench drain retrofit in an existing restaurant kitchen with equipment and tile to be worked around.

Any variable that impacts costs:

  • Drain type (standard, trench, French drain, area drain)
  • Concrete thickness and condition
  • Distance to the existing drain connection
  • Whether a permit and inspection is required
  • Backwater valve or trap primer addition
  • Floor restoration requirements

We provide a written quote prior to any work. No invoices to follow up on that were not discussed.

When the floor drainage system fails, BOS will send an emergency plumber to the business to help with the emergency. We determine what the problem is and attempt to unclog it; if it is a permanent solution, we will be able to offer you the right recommendation.

    FAQs

    Central air conditioner installation on a home with existing ductwork is typically completed in one day. Mini split installation for a single zone takes 3–5 hours. Multi-zone ductless ac installation may require a full day depending on the number of indoor units and complexity of line set routing.

    For most central air conditioner installation work involving electrical connections, a permit is required. BOS manages permit requirements as part of our service, keeping you fully code-compliant without the administrative headache.

    Home depot ac installation services are typically coordinated through third-party subcontractors. BOS is a direct-service, licensed HVAC and plumbing company with 20+ years of GTA experience and full accountability for every job. You work with us from quote to completion.

    Mini splits AC don’t require ductwork and allow room-level temperature control. Central air conditioner installation delivers whole-home cooling through existing ducts from a single system. The right choice depends on your home’s layout, existing infrastructure, and how you want to manage cooling across different spaces. 

    Sometimes, system components need to be matched properly for efficiency and reliability. Our technicians will assess compatibility between existing indoor components and a new outdoor unit before recommending partial versus full system replacement.

    We cover our installations with a workmanship warranty. If an issue develops that’s related to the installation, we return and resolve it at no charge. Call us directly, no third-party warranty service centres, no runaround.
