Our Basement Finishing Process

Here’s a detailed breakdown of what you can expect when you choose onlyBASEMENTS to complete your basement renovation:

Planning & Design

During this stage, our in-house team of architect and designers will work closely with you to understand your goals and preferences. We’ll evaluate your existing space, take accurate measurements, and begin drafting a layout that suits your needs—whether that includes additional bedrooms, a full bathroom, laundry area, entertainment zone, kitchenette, or storage.

We also take into account local building codes, structural considerations, ceiling height, HVAC placement, and more. Once the drawings are finalized, we prepare and submit all necessary applications to the city for building permits. We handle this entire process for you, ensuring everything is compliant with the Ontario Building Code and your municipality’s regulations.

Framing & Layout Construction

Once permits are approved, we begin the framing stage—the physical foundation of your basement’s layout. This is when your future rooms, walls, closets, and corridors start to take shape. Our skilled carpenters build according to the architectural plans, ensuring the framing is strong, square, and perfectly aligned for the drywall and finishes to come later.

Rough-Ins

After framing, we move into the Rough-In Stage.

  • Electrical Wiring: We install all necessary wiring for outlets, pot lights, switches, thermostats, and other electrical components. We can also pre-wire for Audio-Visual Setups, Security Systems, or Smart Home Technology.
  • Plumbing: For bathrooms, laundry rooms, wet bars, or kitchenettes, our licensed plumbers handle the installation of all supply and drain lines.
  • HVAC: If needed, ductwork is adjusted or modified to ensure proper heating, cooling, and ventilation throughout the basement.

Once rough-ins are complete, they are inspected by municipal authorities to ensure full compliance with safety and performance standards.

Insulation & Drywall

Proper insulation is essential for thermal performance, soundproofing, and overall comfort. We use high-quality materials that comply with Ontario’s building code.

After insulation comes drywall installation. Our crew ensures that all panels are properly fitted, secured, and finished. We handle all taping, mudding, sanding, and surface prep to create a clean, seamless canvas for your wall and ceiling finishes.

Interior Finishing

With the drywall complete, we move on to the most exciting phase of the project—the finishing stage. This is where your design vision comes to life.

Our interior designer and project management team will help guide you through every detail, including:

  • Flooring: Choose from a wide range of materials such as engineered hardwood, luxury vinyl plank or tile—depending on the function and style of the space.
  • Trim & Millwork: Baseboards, interior doors, and custom built-ins are added for visual polish and functional storage.
  • Tile & Bathroom Fixtures: Tiles are installed with precision and care, followed by bathroom fixtures.
  • Millwork & Cabinetry: We complete your renovation with custom cabinetry, built-in bars, and tailored millwork features—including wall panels and media walls—installed with precision.
  • Lighting & Ambience: From recessed LED pot lights to decorative pendant fixtures, we create layers of lighting that bring warmth and personality to your new basement.

We source from trusted suppliers and rely on our in-house expert tradespeople to deliver materials and finishes that meet your vision and standards.

Final Walkthrough

Before we consider the project complete, we conduct a thorough walkthrough with you to ensure every element has been finished to your satisfaction. Any final touch-ups or adjustments are addressed promptly. Your satisfaction is our highest priority.
