Spring is the season when GTA backyard projects get planned — and when booking windows fill up fast. Here is what 50+ years across thousands of Toronto-area projects has taught us about the most popular exterior projects, realistic costs, and what to know before you hire.
Most popular exterior projects we see in the GTA:
- Interlock driveway and/or patio replacement
- Deck build or replacement
- Privacy fence replacement
- Flagstone walkway or patio
- Landscaping and garden refresh
- Eavestrough replacement
The booking reality: Quality exterior contractors in the GTA fill their spring calendars well ahead of the season. If you are planning work this summer, the window to confirm a booking is now — not after the long weekend.
Realistic 2026 Cost Ranges
Interlock driveway (two-car): $14,000 – $28,000. Includes base preparation and polymeric sand. Price varies with paver brand and edge detail complexity. Proper 8-inch compacted granular base is non-negotiable in Toronto’s freeze-thaw climate.
Composite deck (16x12 ft): $18,000 – $32,000 installed. Pressure-treated wood runs $12,000 – $22,000 for the same footprint. Any deck over 24 inches from grade requires a building permit in Ontario — include $300 – $800 for permit fees in your planning.
Cedar privacy fence (100 linear feet): $5,000 – $9,000 including posts in concrete. Pressure-treated posts set at frost depth (48 inches in Southern Ontario) are essential; anything shallower heaves.
Flagstone walkway or patio: $6,000 – $20,000+ depending on stone type and sq footage. Natural limestone and bluestone are local favourites; tumbled granite runs higher.
Eavestrough replacement (typical GTA two-storey): $3,500 – $6,000 for seamless aluminum. Add $2,500 – $5,000 if soffit and fascia need work. Micro-mesh guard systems add $2,000 – $5,000.
The Three Questions Worth Asking Before You Book
- What’s in the base? For interlock especially: ask for compacted granular depth and geotextile spec. Thin bases are the number one cause of heaving.
- Are permits included in the quote? Deck permits are a frequent surprise. A reputable contractor pulls permits in their name — it protects you at resale and under your home insurance.
- What does the timeline look like? Get the project start date in writing and tie milestone payments to completion stages, not calendar dates.
