Are icicles a sign of ice damming?

Not always. Small icicles can be normal in winter. However, thick, persistent ice buildup along the eaves and gutters can be a sign of excessive heat loss and ice damming.

Will salt melt an ice dam safely?

Salt can damage gutters and landscaping. Professional steam removal is typically the safest way to remove an ice dam without harming the roof.

Do heated cables prevent ice dams?

Heating cables can help keep melting snow and water flowing in targeted areas, but they do not correct the underlying causes such as heat loss and ventilation issues.

Can ice dams cause mold?

Yes. Ongoing moisture from ice damming can contribute to mold growth, including in attic spaces, especially if wet materials are not dried promptly.

Water Heater Maintenance & Safety: The Ultimate Dos and Don’ts

Nothing makes you appreciate a hot shower like a Montreal winter.

After hours of shoveling snow in freezing temperatures, your water heater becomes the unsung hero of your home. However, without proper care, this essential system can quickly turn into a costly emergency — or even cause major water damage.

At Mose Home Inspection, we inspect water heaters every day across Montreal and Quebec. Whether you are maintaining an existing unit or planning for a replacement, these essential Dos and Don’ts will help protect your investment and your home.

The “Dos” of Water  Heater Maintenance

1. DO Choose the Right Tank Size

If hot water runs out too quickly, your tank may be undersized.

As a general guideline:

A family of four often requires a tank of at least 60 gallons (227 L)

Proper sizing improves comfort and reduces system strain.

2. DO Follow Temperature Safety Guidelines

Set your water heater to 120°F (49°C).
This temperature:

Helps prevent scalding
Limits bacterial growth
Improves energy efficiency

Pro Tip: When leaving for vacation, use “Vacation Mode” or the lowest setting to reduce system pressure and energy use.

3. DO Flush the Tank Annually

Over time, minerals and sediment accumulate at the bottom of the tank.
This buildup:

Reduces efficiency
Causes overheating
Accelerates corrosion

Recommendation: Flush the tank once per year through the drain valve.

4. DO Ensure Proper Placement and Access

Your water heater should remain easily accessible.
Blocked or hidden units can allow small leaks to go unnoticed, leading to:

Mold growth
Structural damage
Insurance complications

5. DO Install Leak Protection When Possible

In finished basements and condominiums, added protection is essential.
Consider:

A drain pan under the tank
A water leak detector
An automatic shut-off valve (where applicable)

These devices can prevent major water damage.

6. DO Understand Your System Type (Gas vs Electric)

Maintenance varies by system:
Gas Water Heaters

Require proper venting
Need adequate combustion air
Must have secure exhaust connections

Electric Water Heaters

Require safe electrical connections
Depend on functioning heating elements

Understanding your system improves safety and performance.

⚠️ The “Don’ts” of  Water Heater Safety

7. DON’T Store Items Near the Heater

Keep flammable materials at least 18 inches (45 cm) away.

Avoid storing:

Paint
Cardboard
Cleaning chemicals

This reduces fire risk.

8. DON’T Ignore Warning Signs

Contact a professional if you notice:

Rust-coloured water
Rumbling or popping noises
Moisture around the base
Temperature fluctuations

Early action prevents major failures.

9. DON’T Ignore the “10-Year Guideline”

In Quebec, many insurance companies recommend replacing water heaters every 10 years.
Older tanks carry higher leak risk and may affect coverage. Always verify with your insurer.

Inspector’s Insight – From the Field

During inspections, we frequently find water heaters installed without proper drainage, clearance, or protection. These small details often become major insurance claims later.
Preventive maintenance saves thousands.
