Stinky Problem: Reasons Why Your Office Smells like a Sewer

Can you smell that? If your office space smells like the sewer, no amount of Glade or essential oils can mask it. You need to get a commercial plumber to get to the bottom of your stinky problem. However, the following are some of the reasons why this is happening:

Improper Venting

One of the most critical aspects of your plumbing is proper venting. If your pipes are not vented properly, the sewer gas can build up in your building, causing the odour to spread.  

A seasoned commercial plumber can analyze your vents to ensure they function correctly. They will also check for any cracks or holes in the vents, which would allow the gas to seep into your building. If a gas leak is found, it should be repaired immediately.

A plumber can install a vapour barrier around the pipes to make a better seal. They can also patch any cracks or even replace any broken lines.

Clogged Vents

When a vent becomes clogged, it can be difficult for your pipes to function correctly. If you fail to fix the ducts, it could cause sewage to spill into your building, which will make the odour even stronger.

If you have noticed a pungent stench coming from your drains and vents, you should hire a commercial plumber to check the vents and gutters. This problem could be the result of a clogged vent. The smell can get so strong that it will permeate through your building.

If your office is located in a strip mall or inside a building, ask the other tenants if they are experiencing the same issues. If you discover the problem is coming from a neighbouring building, you can try speaking to the landlord and see if they can fix the issue.

Backup in Your Sewer Line

If your plumbing is old and outdated, it may not be able to withstand a sudden surge of water when you flush. It is possible for your pipe to get clogged, which can cause sewage to back up into your building. If this occurs, you will smell the sewage very strongly. 

If you suspect a backup in your system, a plumbing professional should be contacted immediately. They will perform a camera inspection or a hydrostatic test to see where the blockage is in your system. The plumber will then clear the blockage and make the necessary repairs.

If you notice that your drain is backed up, it is advisable to contact a professional to get it checked out as soon as possible. The plumber will be able to inspect your pipes to determine the cause of the backup. The sooner you get an expert to solve the problem, the better.

You should also try and avoid flushing any unnecessary items down your toilet. Do not dispose of diapers, wipes, paper towels, feminine products, cotton swabs, or other things that do not break down easily in water. Avoid using your toilet as a trashcan. Doing so could cause severe issues with your plumbing system.


While it is no fun to have an odour seeping through your office, you can take steps to ensure you are breathing fresh air. Finding the cause of the sewer gas is vital to eliminating the odour.
