Is Mold Damage Covered by a Standard Home Insurance Policy?

It depends on what caused the mold. As a general rule, Ontario insurers distinguish between mold that resulted from a sudden, accidental, covered event and mold that developed gradually, which is typically excluded. This table is a general guide only — always confirm the specifics with your own insurance provider or broker. Type of Mold Damage Usually Covered by a Standard Policy? How to Make Sure You're Protected Mold from a sudden event, such as a burst pipe or appliance failure Often yes, since the underlying water damage is typically covered. Report and remediate quickly — most policies require prompt notice and mitigation to keep coverage intact. Mold from a sewer back-up Only with a sewer back-up endorsement added to your policy. Confirm you carry a sewer back-up endorsement, since it's rarely included by default. Mold from overland flooding, such as heavy rain or surface water Only with overland water coverage added to your policy. Confirm you carry overland water coverage, particularly if your property is in a flood-prone area. Mold from gradual leaks or long-term moisture Usually no — treated as a maintenance issue. Address minor leaks and humidity promptly; routine inspections can catch problems before they become exclusions. Pre-existing mold not disclosed at time of purchase No — pre-existing conditions are excluded. Have a professional mold inspection done before purchasing a property.

Sewer Back-up Solutions

Professional support for sewer back-up and affected areas

A sewer back-up is one of the most disruptive events a homeowner can face, bringing contaminated water into your home along with real health risks. DC Premier Construction provides emergency clean-up, sanitization, and full remediation, working alongside your insurance provider to restore your property to Ontario Building Code (OBC) compliant condition.

Professional sewer back-up clean-up and remediation

Sewer Back-Up Solutions

From prevention to emergency response and full clean-up, here's how we help protect your home and restore it after a sewer back-up:

01

Backflow Preventers, Testing & Annual Inspections

A backflow preventer stops sewage from being pushed back into your home when the municipal system is overwhelmed. We install backflow preventers, test existing ones to confirm they're functioning properly, and offer annual inspections to help catch issues before they lead to a back-up.

Emergency Response

What Do I Do If My Sewer Backs Up and Leaks Into My House?

Keep Everyone Away From the Affected Area
Sewage water is contaminated and poses a health risk, so keep children, pets, and household members clear of it.
Stop Using Water in the House
Avoid running taps, flushing toilets, or using appliances that drain into the affected line, as this can add to the back-up.
Call Us
Our emergency line connects you with a team equipped to handle contaminated water safely and begin clean-up right away.
Document the Damage
Take photos and video of the affected areas and belongings before anything is moved, cleaned, or discarded.
Contact Your Insurance Provider
Start your claim as early as possible so coverage and next steps can be confirmed while clean-up is underway.

De-Humidification

After contaminated water is removed, we bring in industrial dehumidifiers and air movers to dry out walls, flooring, and framing, monitoring moisture levels until the space is fully dry and safe from mold growth.

Disposal of Damaged Items

Furniture, flooring, and materials exposed to sewage often can't be safely salvaged and are removed and disposed of following proper health and safety protocols. We recommend photographing and listing damaged items with their approximate value and condition before disposal, since this documentation supports your insurance claim.

Cleaning, Sanitization & Odour Control

Sewage exposure requires more than drying — surfaces need to be disinfected to remove bacteria and contaminants. We clean and sanitize all affected areas using professional-grade products, and treat lingering odours so your home is safe and comfortable again.

Sewer Back-Up Insurance

Insurance Claims

Sewer back-up insurance claims in Ontario can be confusing. Here's what homeowners most often ask:

How It Works

Once you report a sewer back-up to your insurance provider, an adjuster is typically assigned to assess the damage and your coverage under your policy — often a separate sewer back-up endorsement rather than standard water damage coverage. We can attend alongside your adjuster to walk through the scope of remediation work and help align it with what's covered.

When Do We Get Involved?

We can be brought in as early as the emergency response stage, before a claim is even opened, or later once your adjuster has assessed the damage. Involving us early helps ensure contaminated water is removed and the space sanitized right away, which limits health risks and further damage.

Who Pays, When and How?

In most cases, your insurance provider pays for covered remediation work directly or reimburses you after work is completed, depending on your policy and whether you carry sewer back-up coverage. We provide the documentation and invoicing your insurer needs to process payment, and we'll walk you through what's covered versus what falls outside your policy.

Do My Premiums Increase?

A sewer back-up claim may affect your premiums at renewal, but the impact depends on your insurer, your claims history, and the cause of the back-up. Your insurance provider is best positioned to confirm how a specific claim will affect your policy going forward.
