Step-by-Step Process of a Basement Renovation
A well-finished basement can add living space, increase your home’s value, and even generate rental income. But transforming a dark, unused basement into a functional and beautiful space requires planning, permits, and skilled execution.
At B&P Contracting, we’ve simplified the process into clear, manageable steps to guide you from concept to completion.
1. Initial Consultation & Assessment
Every successful basement renovation begins with a conversation. We start by understanding your goals — whether it’s a legal apartment, home office, rec room, or extra bedroom.
We assess:
- Existing conditions (structure, moisture, electrical, etc.)
- Your layout preferences
- Budget and timeline expectations
Tip: This step helps uncover any early red flags like moisture issues or low ceiling height
2. Design & Planning
Once we know what you want, we move into planning and design.
This includes:
- Floor plan layout
- Room placements (bathroom, bedroom, laundry, etc.)
- Electrical and plumbing planning
- Egress window and legal code requirements
We also provide 3D visualizations, so you can see the finished layout before construction starts.
3. Permits & Approvals
We handle all building permits and work with local municipalities to ensure your renovation meets Ontario Building Code requirements — especially important if you’re creating a legal basement apartment.
This includes fire separation, proper ceiling heights, egress windows, and separate entrances when needed.
4. Demolition & Prep Work
With permits in hand, we prepare the space for renovation.
This may include:
- Removing old framing, drywall, or insulation
- Addressing moisture or drainage issues
- Relocating or upgrading wiring and plumbing
- Installing a sump pump or waterproofing, if needed
5. Framing, Insulation & Rough-Ins
We begin to build out the structure of your basement.
- Walls are framed
- Electrical and plumbing rough-ins are completed
- Insulation is installed to meet code and energy efficiency standards
- Soundproofing is added if needed
All rough-ins are inspected before moving to the next step.
6. Drywall, Taping & Finishes
Once inspections are cleared, it’s time for the transformation.
- Drywall is installed and finished
- Painting begins
- Flooring, doors, trims, and baseboards go in
- Final electrical and plumbing fixtures are installed
This is where your space begins to feel like a finished part of your home.
7. Final Touches & Walkthrough
Before we hand over your new space, we take care of:
- Final cleaning
- Finishing carpentry
- Hardware installation
- Touch-ups and quality checks
We’ll walk through the finished space with you to ensure everything is completed to your satisfaction.
8. Your New Basement — Ready to Enjoy
Whether you’re adding income with a legal suite or creating a cozy family retreat, your finished basement is ready to use and enjoy — safely, beautifully, and built to last.
