Lead Paint in Your Dream Home: What to Do (and What Not to Do)

You finally found your dream home.

The location is perfect.

The character is charming.

The price seems reasonable.

But if the house was built before the late 1980s, there may be something hiding beneath those beautiful walls and trim:

Lead-based paint.

Many older homes throughout Toronto, Markham, North York, Vaughan, Scarborough, and other GTA communities still contain lead paint underneath multiple layers of newer paint.

The good news?

Finding lead paint does not mean you should walk away from the property.

However, it does mean you should understand the risks and avoid some very common renovation mistakes.

What Is Lead Paint?

Lead paint was widely used in residential construction for decades because it was durable, moisture-resistant, and long-lasting.

In Canada, residential lead paint use began to decline in the 1970s and was heavily restricted by the late 1980s.

As a result, many homes built before 1990 may still contain lead paint on:

• Walls
• Window frames
• Baseboards
• Doors
• Crown mouldings
• Stair railings
• Exterior siding
• Porch railings

Even if the visible paint appears modern, older layers underneath may still contain lead.

Why Is Lead Paint a Concern?

Lead paint is generally not dangerous when it remains intact and undisturbed.

The problem occurs when renovation work creates:

• Dust
• Paint chips
• Sanding debris
• Demolition waste

Lead dust can become airborne and settle throughout a home.

Exposure may be particularly concerning for:

• Children
• Pregnant women
• Elderly occupants
• People with respiratory conditions

This is why older-home renovations require additional planning and precautions.

How to Tell if a Home May Have Lead Paint

There is no way to confirm lead paint simply by looking at a wall.

However, there are warning signs.

The property may contain lead paint if:

• The home was built before 1990
• Original trim remains in place
• Original wood windows are still installed
• Multiple layers of paint are visible
• Paint is peeling or cracking

The most reliable option is professional testing before renovation begins.

What To Do If You Suspect Lead Paint

1. Get the Home Tested

Professional lead testing is the safest and most accurate approach.

Testing can identify:

• Whether lead is present
• Which surfaces contain lead
• The concentration level
• Areas requiring special handling

Testing before demolition helps avoid surprises during construction.

2. Inform Your Contractor

Never assume your contractor already knows the property's history.

If you suspect lead paint, inform your renovation team before work begins.

Experienced contractors can adjust their procedures to reduce contamination risks.

3. Plan Renovation Work Properly

Older-home renovations often require:

• Containment barriers
• Dust-control measures
• Specialized cleanup procedures
• Protective equipment

Planning ahead can significantly reduce health risks and project delays.

4. Keep Children and Pets Away from Work Areas

Lead dust is often invisible.

During renovation, children and pets should remain away from active construction zones until cleaning is completed.

5. Follow Local Regulations

Depending on the scope of renovation, permits and specific safety requirements may apply.

Working with qualified renovation professionals helps ensure compliance and safer project execution.

What NOT To Do

❌ Don't Start Sanding Immediately

One of the biggest mistakes homeowners make is aggressively sanding old painted surfaces before testing.

Sanding can release significant amounts of lead-contaminated dust.

❌ Don't Use Open-Flame Paint Removal

Using torches or high-heat methods on older painted surfaces can release hazardous fumes.

This approach should generally be avoided unless performed under proper safety controls.

❌ Don't Assume New Paint Solves the Problem

Applying fresh paint over damaged lead paint without proper preparation may only hide the issue temporarily.

Underlying deterioration can continue.

❌ Don't Let DIY Demolition Create Dust Everywhere

Removing walls, trim, doors, or ceilings without proper containment can spread contamination throughout the home.

❌ Don't Ignore Exterior Lead Paint

Many homeowners focus only on interior spaces.

Older exterior siding, porches, windows, and railings may also contain lead-based paint.

Can Lead Paint Be Removed?

Yes.

Several approaches may be used depending on the condition of the surface:

Encapsulation

A specialized coating seals the existing lead paint beneath a protective barrier.

Enclosure

New materials are installed over affected surfaces.

Removal

The lead paint is removed using approved methods and safety procedures.

The appropriate solution depends on the condition of the home, renovation goals, and budget.

Should You Avoid Buying a Home Because of Lead Paint?

Not necessarily.

Many beautiful Toronto-area homes contain lead paint and are renovated successfully every year.

Lead paint is often a manageable renovation issue rather than a deal-breaker.

The key is understanding:

• Where it exists
• How to handle it safely
• What precautions should be taken during construction

A proper inspection and renovation plan can help homeowners make informed decisions.
