When Water or Floods Damage Your Property

Almost 70% of property damage involves water – through flooding, broken pipes, sewer backups or after a fire. Water can cause extensive damage and pose a serious threat to building structures, interior furnishings, important documents and prized belongings. Another danger is that mould can begin growing within 24–48 hours. Mould growth and related bacteria and allergens can result in serious long-term, health issues.

Main causes of floods

Floods are the costliest natural disasters in Canada in terms of property damage. While floods can affect any region, regardless of geographic area and time of year, these scenarios carry the biggest risks:

  • Spring thaws, the most common cause of flooding in Canada. Sudden winter thaws can also cause floods. Basements are particularly prone to flooding during thaws.
  • Heavy snowfalls, especially when quickly followed by warm weather and thawing.
  • Heavy rains caused by thunderstorms, tropical storms and hurricanes, leading to risk of flash floods.
  • Rising rivers in spring due to melting of ice, affecting areas close to rivers, lakes and coastal shorelines.
  • Ice jams caused by fragments of ice building up in rivers in spring, creating a blockage.

How We Help

If your home or business has been damaged by water or flooding, it is critical to seek help within the first 24 hours to prevent further damage and loss of property. An affected building is often unsafe to inhabit, due to structural damage, and the threat of mould and contamination from sewage, rotting materials – even asbestos if it is already present in the building.

FirstOnSite Restoration specialists are certified by the Institute of Inspection Cleaning and Restoration Certification (IICRC) – meaning they know what to look for and which methods to best use.

We follow a step-by-step process to return your property to its pre-loss condition:

  • Determining the source of water entry and extent of damage. Items are also removed from the property, or protected, so that restoration can begin.
  • Extracting water using powerful pumps and vacuums. Water must be removed quickly to prevent the breakdown of building materials and the growth of mould and other harmful bacteria.
  • Installing drying and dehumidification equipment. We use moisture meters and thermal imaging cameras to properly diagnose damage and ensure that no moisture goes undetected. This equipment remains in place until the area has been dried/dehumidified to industry standards, verified through daily moisture and humidity readings.
  • Cleaning and sanitizing affected areas, using anti-fungal and anti-microbial treatments. Removed items are also thoroughly cleaned, if needed, and air-scrubbing equipment may be installed to remove toxins from the air.
  • Restoring the property fully, including structural repairs, replacing drywall, painting, installing new flooring, and making any other repairs needed.
  • Securing temporary power and heat as soon as the building is safe for human occupation – especially in the case of commercial properties, to minimize disruption to your business.

Our dedicated resources and state-of-the-art equipment are stationed across Canada to serve at a moment’s notice. We are available to respond to emergency calls 24 hours/day, 7 days a week.
