Project #82 — Woodbridge, Ontario

Quick Facts

  • Location: Woodbridge (Project 82)
  • Duration: ~3 weeks
  • Service Provided: Basement Renovation
  • Project Area: ~950 sq ft

The homeowners in Woodbridge wanted to convert their unused basement into a bright, dry, and livable family space.
Reno Mumu designed a plan focused on moisture-proof construction, engineered flooring, and modern LED lighting, creating a warm environment that feels like an extension of the main floor — not a basement.

Design Goals

  1. Full waterproofing system to protect against basement humidity and groundwater.
  2. Engineered wood flooring for warmth, stability, and noise reduction.
  3. Upgraded insulation to improve comfort and reduce heat loss.
  4. LED lighting layout for bright, energy-efficient illumination.
  5. Durable wall and ceiling finishes designed for long-term reliability.

Materials & Specifications

Flooring & Subfloor System

  • Engineered oak planks (7.5”), UV matte finish, low maintenance.
  • Raised vapor-barrier subfloor panels with air channels to prevent mold.
  • Self-leveling concrete base underlay for perfect alignment.
  • Sound-dampening underpad (3 mm) installed for noise control.

Waterproofing & Insulation

  • Interior perimeter waterproof coating applied to concrete walls.
  • 2” rigid foam insulation (R-10) with sealed joints for vapor protection.
  • Framing treated with anti-fungal primer.
  • Spray foam applied around rim joists and window openings.

Walls & Ceiling

  • Metal stud framing with fiberglass insulation (R-14).
  • Moisture-resistant drywall finished with washable matte paint.
  • Drop ceiling with recessed LED panels and sound insulation layer.

Lighting & Electrical

  • 4000 K LED pot lights with dimmer switch for different lighting zones.
  • Dedicated 20 A outlets for entertainment and dehumidifier systems.
  • Smoke and CO detectors installed as per Ontario Building Code.

Challenges & Solutions

  • Moisture control: Installed a full vapor barrier and subfloor ventilation channels to prevent future dampness.
  • Uneven foundation slab: Leveled with self-leveling underlayment before flooring installation.
  • Sound management: Added acoustic insulation above the ceiling to reduce footstep noise from upper floors.
  • Energy efficiency: Used LED lighting and sealed insulation to reduce energy costs by ~20%.

Investment Range (Guide Only)

A basement renovation of this quality and size typically ranges $38 k – $55 k + HST, depending on layout changes and material upgrades.
