Pricing & What Affects the Cost
Simple refreshes are most affordable; costs rise with bathrooms/kitchenettes, egress/walkouts, custom millwork, and high-end finishes.
Typical price drivers:
• Scope & size: Full finish vs. zone upgrades; square footage.
• Plumbing/Electrical: New rough-ins, added circuits, panel capacity.
• Moisture & subfloor: Drainage, vapor control, leveling systems.
• Walls/ceilings: Soundproofing, bulkheads, ceiling height solutions.
• Finishes: Tile complexity, custom cabinetry, specialty lighting.
You’ll receive a written, line-item estimate with allowances and a realistic contingency so you can compare options side by side.
Moisture, Egress & Code (Make It Last and Pass)
Basements succeed when we handle fundamentals first:
- Moisture: Check sources, seal penetrations, manage vapor, and select subfloor systems appropriate to slab and humidity.
• Egress & Safety: Window size/height, clear paths, smoke/CO protection, and proper stair/handrail details.
• Electrical/Plumbing: GFCI/AFCI where required, adequate ventilation, sump/backwater considerations.
For secondary suites, we’ll outline permit steps, drawings, inspections, and what’s needed for compliance.

Mini Case Study
A Whitby homeowner wanted a family room + office with a future-ready bath rough-in. We added a moisture-smart subfloor, insulated/air-sealed exterior walls, ran dedicated lighting circuits with dimming, framed a quiet office nook, and capped rough-ins for a later bath. Result: a warm, bright lower level now—plus lower cost when they add the bathroom later.

- Higher Home Value: Quality finishes and compliant suites improve resale and rental potential.
- Health & Efficiency: Better insulation, ventilation, and moisture control.
- Flexible Layouts: Design for today; adapt for tomorrow.
