Why Does Mold Keep Coming Back in an Ottawa House? Causes and Solutions

You clean a patch of mold on the bathroom ceiling and scrub the surface neatly. After a while, you observe the same mold again. This might be something you have experienced in your home.

In Ottawa, seasonal temperature changes, winter condensation, basement moisture, and water intrusion can all contribute to mold problems. Understanding these causes can help homeowners take the right steps towards lasting mold control.

This recurring mold could be a sign of an underlying moisture problem and may need professional mold inspection and remediation. ONT Restoration offers mold removal and remediation services for residential and commercial properties in Ottawa.

Let’s learn the common causes of mold.

What Cause Molds

The Source of Moisture Has Not Been Identified

Cause: One of the common causes of mold arises from its hidden source. In Ottawa homes, moisture can enter through foundation cracks, leaking pipes, damaged roof components, or poorly sealed windows. Even a small plumbing leak behind a cabinet or inside a wall can create conditions for mold growth.

What you can do: Identify the signs of moisture or dampness in your house. Check for plumbing leaks, water stains, damp building materials, and signs of water entering through the foundation.

 If the source is hidden, you can call professional mold inspection services. Persistent or concealed leaks may require professional assessment.

Ottawa’s Seasonal Changes Encourage Condensation

Ottawa experiences cold winters and seasonal temperature fluctuations. Cold temperatures cause dampness, and warmth favours mold growth.

When moisture repeatedly collects on these surfaces, mold may begin to grow. The problem can continue if condensation is not addressed, even when there is no plumbing leak or obvious water damage.

What you can do: maintain proper flow of air inside the house. Wipe away condensation when it appears and investigate surfaces that remain damp.

Basement Dampness Favours Mold Growth

Basements are particularly vulnerable to moisture. Moisture can enter through foundation cracks, improper sealing of doors and windows, and other drainage issues.

A basement may appear dry while moisture remains behind stored items, finished walls, carpets, or flooring. These concealed areas can create a favorable environment for mold development.

What you can do: Check your basement for musty odours, water stains, and peeling paint. Manage the humidity levels of the room, or for more help, call professionals.

How Professional Mold Remediation Helps Prevent Mold Recurrence

When you observe recurring mold in your Ottawa house, it is recommended to call for professional help.

Professionals will inspect the mold, identify the hidden cause of mold, and their professional mold removal process will remove the mold and reduce the risk of its recurrence. 

Professional mold remediation in Ottawa can help address the problem more thoroughly.

The process generally involves identifying the affected areas, assessing moisture conditions, and establishing appropriate containment where necessary.

The affected area will be sealed to prevent the spread of mold. After that, professionals will remove mold and clean the surface.

Proper sanitizing and dehumidification will be done to restore the indoor air quality of your house.
