Exterior renovation costs by city: siding, doors, garages and more in 2026

By the Return on Reno team · Reviewed August 2026 · ~6 min read

Exterior projects consistently deliver the best ROI of any renovation category — eight of the top ten projects by resale recoup rate are exterior work (see our exterior ROI guide). But what these projects actually cost depends heavily on where you live. Labour rates, climate-driven material requirements, and local building codes can swing prices 30–60% between cities for the same project. This guide covers three of the most searched exterior renovations — vinyl siding replacement, front door replacement, and garage extensions — with city-level pricing across North America, Australia and New Zealand.

Vinyl siding replacement

Replacing vinyl siding is one of the highest-ROI exterior projects, typically recouping 70–80% of its cost at resale. The national US midrange is roughly $16,000–$18,000 for a typical two-storey home (1,500–2,000 sq ft of siding). Here is how it varies by city:

• Calgary, AB: C$18,000–$25,000. Alberta’s extreme temperature swings demand insulated vinyl or fibre-cement rated for −40°C, and the short outdoor-work season (May–October) compresses builder availability.
• Toronto, ON: C$16,000–$22,000. Similar climate constraints to Calgary but a deeper contractor pool keeps prices slightly lower.
• Dallas, TX: US$12,000–$16,000. Year-round installation season and lower labour rates make Texas one of the cheapest markets for siding work.
• Chicago, IL: US$16,000–$22,000. Cold-climate insulation requirements and union labour rates push costs above the national average.
• Denver, CO: US$15,000–$20,000. Moderate labour costs but high UV exposure at altitude means premium UV-resistant vinyl is recommended, adding material cost.

The biggest cost variable beyond labour is whether the old siding conceals issues — rotted sheathing, inadequate house wrap, or asbestos-containing materials (common in homes built before 1980). Remediation of any of these can add $3,000–$10,000 to the project. Always budget 10–15% contingency for what the old siding is hiding.

Front door replacement

A front door replacement is the single highest-ROI renovation project in most datasets — recouping 90–100%+ of its cost at resale. It is also one of the cheapest, with a national US midrange of $2,500–$5,000 installed (steel or fibreglass entry door with new hardware, weatherstripping and trim). City variation is narrower than for larger projects, but still meaningful:

• Brisbane, AU: A$3,000–$5,500. Hardwood timber doors are popular in the Queensland market and cost more than steel or fibreglass, but they suit the local aesthetic and perform well in the subtropical climate.
• Melbourne, AU: A$3,500–$6,000. Higher trade rates than Brisbane; many heritage-overlay suburbs require council approval for front-facing changes, adding time and sometimes design constraints.
• Calgary, AB: C$3,500–$5,500. Insulated steel doors dominate in cold climates; the R-value requirement effectively rules out uninsulated options.
• Houston, TX: US$2,000–$4,000. One of the cheapest markets — mild climate means no extreme insulation requirements, and competition among installers is strong.
• New York Metro: US$3,500–$6,000. High labour costs and the prevalence of custom-width openings in older homes push prices up.

For maximum ROI, focus the budget on the door and hardware quality rather than sidelights or transoms — a high-quality door with good hardware in a standard opening delivers the best cost-to-impact ratio. The door is the single most visible element of your home’s curb appeal; buyers form opinions in the first seven seconds of seeing a house.

Garage extension

Building a new garage or extending an existing one is a bigger-ticket exterior project — the national US midrange is roughly $35,000, ranging from $25,000 for a basic single detached garage to $55,000+ for a large attached double with heating and finished interior. City-level variation is significant:

• Wellington, NZ: NZ$45,000–$70,000. Wellington’s hilly terrain, earthquake-strengthening requirements, and high construction costs make garage builds expensive. Covered parking is valued by buyers in a city known for wind and rain.
• Auckland, NZ: NZ$40,000–$65,000. Similar cost drivers to Wellington but flatter terrain in many suburbs reduces foundation costs.
• Adelaide, AU: A$30,000–$50,000. One of the more affordable Australian markets for garage construction, with straightforward council approval processes in most suburbs.
• Perth, AU: A$28,000–$48,000. Low-cost market with sandy soil (cheap foundations) and a strong local prefab garage industry.
• Calgary, AB: C$35,000–$55,000. Heated garages are standard expectation; the foundation must extend below the frost line (typically 4+ feet), adding structural cost.

A garage extension recoups about 60% of its cost nationally, but the return is highest where covered parking is expected and the home currently lacks it. In Wellington, where wind, rain and steep driveways make garages highly valued, the payback can approach 80%. In suburban markets where every home already has a double garage, adding a third bay has a much lower marginal return. See our garage extension cost page for the full breakdown.

What drives exterior renovation costs by city

Across all three project types, the same four factors explain most of the geographic variation:

Labour rates account for 40–60% of exterior project costs. Cities with strong union presence (Chicago, New York, Toronto) or tight trade labour markets (Sydney, Auckland) consistently run 20–40% above the national average.

Climate-driven specifications. Cold climates require insulated materials, deeper foundations, and weather barriers that add material cost. Hot-humid climates (Miami, Brisbane) require moisture-resistant materials and sometimes hurricane or cyclone ratings. Temperate markets (Dallas, Adelaide) generally have the lowest specification requirements.

Building code and permit complexity. Heritage overlays, earthquake zones, and cyclone-rated regions all add design, engineering and inspection costs. A simple siding replacement that requires no permit in suburban Texas may need council approval, a heritage architect’s report, and multiple inspections in inner Melbourne.

Supply chain and material availability. In New Zealand, many building materials are imported, adding freight cost. In remote Australian and Canadian cities, specialty items have longer lead times and higher delivery costs. In the US, the domestic manufacturing base for siding, doors and garage components keeps material costs relatively stable across regions.

Getting the best value on exterior work

• Bundle projects. If you need siding, a front door and gutters, doing them together saves on scaffolding and mobilisation costs — often 15–20% versus doing each separately.
• Time it right. Exterior work is weather-dependent. In cold climates, booking for early spring (before the rush) can save 10%. In hot climates, summer is the slow season — builders discount to fill gaps.
• Check for rebates. Some jurisdictions offer energy-efficiency rebates for insulated siding, high-R-value doors, or solar-ready garage builds. Worth checking before you commit.
• Prioritise by ROI. If budget is limited, the front door delivers the most value per dollar spent. Siding is next. A garage extension is worth it mainly when the home genuinely lacks covered parking.
