Exterior demolition is exciting — it’s the first real step toward creating something new. But without a smart plan, it can also turn into a stressful, costly mess. At Démo Prép Montréal, we believe proper planning is the secret to smooth, stress-free demolition.

Whether you’re tearing down a garage, knocking off a porch, or removing a full house facade, here’s your ultimate checklist for success.

1. Get a Clear Demolition Scope

Before the first brick falls, be crystal clear on:

• What exactly needs to be demolished?

• What needs to stay intact?

• What are the hidden structures (pipes, electrical lines) you need to protect?

A detailed scope helps avoid costly mistakes later.

2. Secure the Right Permits

In Montreal, you can’t legally demolish exterior structures without proper city permits. Different boroughs (like Plateau-Mont-Royal, Villeray–Saint-Michel–Parc-Extension, or Outremont) have different rules.

Démo Prép Montréal handles all paperwork, so you avoid legal troubles and expensive delays.

3. Prepare for Utility Shut-Offs

Before demolition starts, make sure:

• Gas lines are safely capped

• Water and sewer lines are disconnected (if necessary)

• Electrical systems are powered down

Overlooking this step can cause dangerous accidents — not to mention hefty repair bills.

4. Plan for Debris Removal

Exterior demolition creates a LOT of waste — bricks, wood, concrete, metal, and sometimes hazardous materials.

At DemoPrep, we bring the right dumpsters, organize recycling for reusable materials, and follow strict environmental practices. You don’t want piles of rubble sitting around after demolition.

5. Protect Surrounding Structures

Got a neighbor’s fence right next door? A tree you want to save? Foundation you’re keeping?
We use protective barriers, smart machinery placement, and precision techniques to demolish only what’s needed.

6. Have a Timeline — and a Backup Plan

Exterior demolition can hit surprises like:

• Hidden water damage

• Asbestos or lead paint

• Unstable structures needing special handling

We build flexible timelines that prepare for these issues, keeping your project moving even when the unexpected pops up.
