    Planning Your Basement Finish

    #

    Assess the Space

    Before planning, evaluate:

    - Ceiling height: Minimum 7 feet for most uses (check local codes)
    - Moisture issues: Any water intrusion or dampness?
    - Mechanicals: Furnace, water heater, electrical panel locations
    - Windows: Natural light and emergency egress

    #

    Address Moisture First

    Ottawa basements face moisture challenges:

    - Exterior waterproofing: Address from outside if needed
    - Interior drainage: Sump pump, drain tile
    - Vapor barrier: Prevent moisture through walls
    - Dehumidification: Control humidity levels

    #

    Design Considerations

    ##

    Layout Planning

    - Work around support columns and mechanicals
    - Plan for egress windows in bedrooms
    - Consider soundproofing between floors
    - Include storage solutions

    ##

    Ceiling Options

    - Drywall: Clean look, hides everything
    - Drop ceiling: Easy access to mechanicals
    - Exposed: Industrial look, maximum height
    - Combination: Drywall with access panels

    ##

    Flooring Choices

    - Luxury vinyl plank: Waterproof, comfortable, stylish
    - Tile: Durable, water-resistant
    - Carpet: Warm, sound-absorbing (use moisture-resistant pad)
    - Epoxy: Great for gyms and workshops
    - Engineered hardwood: Wood look with better moisture resistance

    Key Systems

    #

    Heating and Cooling

    Basements need climate control:

    - Extend existing HVAC: Add registers and returns
    - Ductless mini-split: Efficient, independent control
    - Electric baseboard: Simple, zone heating
    - Radiant floor heating: Luxurious warmth underfoot

    #

    Electrical

    Plan for adequate power:

    - Multiple circuits: Avoid overloading
    - Plenty of outlets: Every 6-8 feet on walls
    - Dedicated circuits: For home theater, gym equipment
    - Lighting: Layered approach—overhead, task, accent

    #

    Plumbing

    Adding a bathroom increases value and functionality:

    - Above-floor system: For ejector pump situations
    - Traditional plumbing: If main line is accessible
    - Rough-in only: Save money now, finish later
