1. Finalize the Demolition Scope
Before anything is torn down, make sure your demolition contractor has a detailed understanding of what needs to go. Walls, ceilings, floors, fixtures? Be specific. A well-defined scope prevents miscommunication and ensures nothing gets removed unintentionally.
- Mark areas to be demolished with tape or paint.
- Clarify if electrical, plumbing, or HVAC components need removal.
- Get all permits and approvals in writing.
2. Remove All Personal Belongings
This may seem obvious, but it’s often overlooked. Anything left in a demolition zone risks being damaged or coated in dust. Clear out:
- Furniture, electronics, and décor
- Wall hangings, curtains, and blinds
- Appliances (if not being removed by the crew)
- Anything stored in adjacent rooms that could shift or be damaged
3. Turn Off and Disconnect Utilities
Your demolition crew cannot start without this step being complete. For safety and code compliance, utilities must be shut down and disconnected properly:
- Electricity: Turn off power to affected areas at the breaker box. Remove fixtures if needed.
- Plumbing: Shut off water lines and drain them if necessary. Cap pipes.
- Gas: Hire a licensed technician to disconnect gas lines before demo.
Document the status of each utility and label all shut-offs clearly.
4. Seal Off the Work Zone
Dust is demolition’s silent weapon. It gets everywhere. Seal off the work zone with heavy plastic sheeting and painter’s tape to reduce the spread of debris to the rest of your home.
- Cover vents and air returns with plastic.
- Close doors or install zipper dust barriers.
- Lay floor protection for paths the crew will walk through.
5. Confirm Asbestos and Lead Testing
Any home built before the 1990s should be tested for asbestos and lead paint before demolition. Do not assume this has been done.
- Hire a certified environmental contractor to test samples.
- Provide results to your demolition contractor in advance.
- If hazardous materials are found, abatement must be completed before demo day.
6. Inform Your Neighbors
Interior demolition can be noisy, dusty, and disruptive — especially in condos, duplexes, or tight urban neighborhoods. Give your neighbors a heads-up:
- Let them know your demolition schedule.
- Assure them you’ve hired licensed professionals.
- Share contact info in case they have concerns.
This avoids complaints and keeps your renovation on good terms with the community.
7. Create a Safe Zone for Kids and Pets
Children and pets should be nowhere near the demolition zone. Make arrangements:
- Send pets to daycare or a friend’s home during the demo.
- Set up child-proof barriers if you’re staying on-site.
- Have an off-site plan in case noise or dust becomes overwhelming.
8. Document Everything With Photos
Take detailed photos of the interior space before demolition begins. These can help if any issues arise during renovation, and they’re useful for future reference or insurance.
- Capture images of walls, floors, ceilings, and visible utility connections.
- Label photos by room for clarity.
- Store copies both digitally and on a backup drive.
9. Review the Crew’s Arrival Plan
Coordinate with your contractor about:
- Arrival time and access points
- Parking availability for trucks and dumpsters
- Which entrances to use (and which to avoid)
Being on-site during the first 30 minutes is ideal to answer questions and ensure the job starts correctly.
10. Have a Post-Demo Cleanup Plan
Interior demolition leaves a mess. Ask if post-demo cleanup is included in your contract — and if not, be ready to schedule one. You may need:
- Debris removal or dumpster service
- Professional cleaning for dust
- HVAC filter replacements
Some companies, like DemoPrep in Montreal, include both demo and cleanup in their services — saving you time and hassle.
