Landscaping options and costs in London
London is a classic Southwestern Ontario market where many homeowners have room (and motivation) to improve curb appeal—about 48.8% of dwellings are single-detached homes, and 58.1% of households are homeowner households (Statistics Canada, 2021 Census). That combination usually means heavier demand for full-service landscape builds in neighbourhoods with mature lots and established streetscapes.
In London, pricing is shaped by our plant hardiness range (Zone 5b–6a), freeze-thaw cycles, and clay-heavy soils. Projects typically run on a roughly five-month main working season, because contractors plan around early-May last frost and a mid-October first frost. That affects availability and scheduling: crews often book out spring and early summer first, and fall planting may be limited to hardy species that can establish before cold snaps. To prevent patio and wall movement, we also plan deeper, well-drained bases than you’d see in coastal climates—often 12–18 inches of compacted base—so excavation and drainage work can be a major cost driver.
We’re busiest where long-established homeowners want “year-round, not just summer” results, including areas like East London (near Fanshawe Park and Longwoods Road corridors) where many properties have older foundations and established shrub beds that need refresh, regrading, and sometimes drainage repairs.
Below is a practical cost comparison you can use to sanity-check quotes; then we’ll break down why the same scope can land 30–50% apart across London.

What affects the price of landscaping in London
In London, Ontario, two homeowners can receive quotes that look similar on paper yet land 30–50% apart. The main reason is that “landscaping” usually includes hidden work—grading corrections, drainage fixes, excavation depth, and material tiering—not just the visible finish. Labour and machinery time also vary by lot access, driveway width, and how much equipment can reach the backyard. Because London sits in plant hardiness zones 5b–6a with an early-May last frost and a mid-October first frost, crews schedule around a roughly five-month main working season; that compresses the time available to book labour-intensive builds.
Climate and hardiness also affect what you buy and how you build. Zone 5–6 conditions mean we choose plants that tolerate winter desiccation and shoulder-season frosts. That’s different from Prairie regions (Zone 2–4), where short growing seasons and wind demand drought- and cold-hardy choices, and from coastal BC (Zone 7–8), where lush palettes are possible but drainage in heavy rain is the priority. For London, freeze-thaw cycles and clay soils drive deeper, well-drained bases for patios and retaining work—often 12–18 inches of compacted base—to reduce heaving and movement. Good irrigation design still matters for summer dry spells, even though water restrictions are typically less strict than in the dry BC interior.
Concrete examples that raise or lower cost in London: (1) correcting a slope that sends runoff toward a foundation can require extra excavation and drainage bed work, pushing the project toward the upper end of retaining wall & hardscape budgets (for example, $4,000–$35,000). (2) switching from seeding to sod can swing lawn budgets quickly, often moving from the seeding-style band toward the higher sod installation band ($2,500–$8,000) when you also need soil build-up. (3) In older housing stock—where 52.3% of homes were built before 1981—there may be settling, mature root zones, or outdated drainage routing that adds labour and disposal costs.
| Price Factor |
Why It Matters |
Cost Impact |
| Yard size in sq ft — the primary cost driver for softscape |
More turf/bed area means more materials, soil amendments, and labour hours |
Typically shifts budgets most of all; can move costs by $1,000s |
| Grading and drainage work — slope corrections add significant cost |
Fixing pooling and foundation runoff requires excavation, recontouring and often engineered drainage |
Often adds the biggest “hidden” cost; can increase total by 15–35% |
| Drainage bed or French drain installation |
Clay soils and freeze-thaw demand proper sub-surface drainage to prevent heaving and water pressure |
Can add several thousand dollars depending on length and outlet |
| Plant material tier — native shrubs vs. ornamental vs. mature specimen trees |
Mature trees cost more, take longer to install, and may need extra support and site prep |
May change planting budgets by $800–$6,000+ depending on specimen size |
| Hardscape vs. softscape ratio — walls and patios cost more per sq ft than lawn |
Pavers and retaining blocks require deeper bases, compaction, and precise layout |
Shifts project toward the $4,000–$35,000 band for retaining/hardscape-heavy work |
| Irrigation system design and installation |
Zoning, valves, trenching and controller setup determine both effectiveness and cost |
Can add a meaningful “middle” budget tier; increases when water routing is complex |
| Soil amendment and topsoil required |
Clay improvement, compost blending and proper depth affect plant survival and turf performance |
Usually adds cost proportional to how much import soil is needed |
| Tree removal or stump grinding before new planting |
Roots and stumps affect excavation and planting layouts |
Can add several hundred to several thousand depending on access and debris hauling |
Permits & regulations in Ontario
In Ontario, most planting and soft landscaping work does not require a permit. Typical examples that generally do not need permits include: sod and seeding, planting beds, mulching, laying topsoil, building small garden features like raised beds (when they don’t trigger retaining-wall rules), and installing interlocking patios/walkways. However, homeowners should always confirm with the City of London if their specific layout touches lot drainage or any structure near property lines.
Where permits do come into play: retaining walls above the common threshold of 1.0 m (3.3 ft) in many Ontario municipalities typically require a building permit and sometimes engineered drawings. Also, changes to lot grading that redirect drainage toward neighbouring properties or storm sewer connections may trigger approval requirements. If a contractor is excavating for drainage, footings, or wall bases, it’s wise to ask what approvals (if any) are required for the exact design.
Before any digging—whether for planting holes or wall footings—require utility locates. In Ontario, call before you dig so crews don’t hit gas, hydro, or communication lines.
To verify a contractor in London step-by-step: (1) check the contractor’s trade/registration status with Ontario’s relevant online resources, if applicable to their work category; (2) request a certificate of insurance naming you as an additional insured (general liability at minimum); and (3) confirm WSIB/WCB coverage for labour—ask for current clearances. Look for these items in the quote package or insurance/clearance certificates. Then verify the details match the company name on the contract and invoices.
Planning a landscape that thrives in London’s climate
Planning for London’s climate means building a yard that survives our frost calendar instead of fighting it. London sits in hardiness zones 5b–6a, with shoulder-season freezes and freeze-thaw cycles that can heave poorly built flatwork. Start with plant selection: choose zone-appropriate, native-leaning trees and perennials that handle winter desiccation and spring thaws. For turf, balance speed with resilience—sod gives instant curb appeal, but it’s less forgiving if drainage is off; seeding can take longer but is often better for long-term adaptation when the bed prep is right.
Drainage and grading are the make-or-break items. Clay soils plus winter expansion means patio and wall base prep should be deep and well-drained—typically 12–18 inches of compacted base plus proper sub-surface drainage where needed. When pooling exists, fix grading first; otherwise, even “premium” interlocking or fresh topsoil will settle or shift.
Hardscape also needs to be designed for Ontario winters: edges, compaction, and correct bedding sand matter because water and pressure find weak spots during freeze cycles. If you’re trying to manage ongoing maintenance, prioritize mulch zones, groundcovers, and layered perennial groupings instead of lots of small, high-weed beds.
For water-smart options, consider a rain garden in low spots (where water naturally accumulates) and drip irrigation on established plantings. While London’s restrictions are usually less severe than dry interior regions, smart irrigation still protects plants and controls utility costs.
Example: if you want an instant green look, sod may be budgeted around $2,500–$8,000. If your soil prep is solid and you’re comfortable waiting for full density, seeding plus correct topdressing can be more economical, and the “savings” are best spent on drainage improvements—because correcting a poor slope or compaction issue can prevent expensive redo work.

How to choose a landscaping contractor in London
Choosing the right contractor in London comes down to proof of coverage, a detailed scope, and a build process that accounts for frost and drainage—not just pretty renderings. Start by verifying Ontario coverage: request a certificate of liability insurance (and confirm it’s active), then ask for WSIB/WCB clearance for the workers who will be on your site. How to check each: (1) insurance certificate—ensure the policy number and limits are current and matches the legal company name; (2) WSIB/WCB—ask for the most recent clearance letter or documentation; (3) licensing/registrations where applicable—check the contractor’s details against online records and confirm the company operates under the name on your agreement. If they can’t provide documentation quickly, treat that as a red flag.
Next, get 2–3 itemised written quotes. Ask for a breakdown that separates labour and materials (base prep, geotextile, compaction, stone quantity, disposal fees, and drainage elements). Review exclusions: is permit pulling included (if required), who hauls away excavated soil, and is grading to finished elevations included? Make sure the quote specifies workmanship details that matter in London—like the base depth, edging, and whether a drainage bed/French drain is included for clay and pooling areas.
Warranty matters too. Confirm workmanship warranty length and whether product warranties (pavers, blocks, sod, or trees) transfer to you. For payment, avoid large deposits: never pay more than 10–15% upfront; hold back a portion until the job is substantially complete and cleanup is done. Finally, insist on a written start date and completion estimate so you can plan around the frost-limited working season.
- They provide proof of insurance and WSIB/WCB coverage before work starts.
- Quote is itemised (labour + materials), not one lump sum.
- Base preparation details are written: compacted depth, geotextile, and bedding sand.
- Drainage plan is included for clay or low spots (not “we’ll see later”).
- Disposal/hauling and site cleanup are clearly listed.
- Vegetation installation dates are planned for London’s frost calendar.
- Warranty terms are specific (workmanship length, product coverage, transferability).
- They list which permits are included or confirm “not required” in writing.
- They show how setbacks and property lines will be respected.
- They include irrigation scope if you’re adding turf/planting irrigation.
- Payment schedule is staged and tied to milestones (no “pay all at start”).
- They provide a signed contract with measurable specs and allowances.
In London, watch for these red flags: “no paperwork” on insurance/WSIB/WCB, vague scope that doesn’t state base depth or drainage responsibility, cash-only or unusually high deposits, start dates that keep shifting with no written updates, and quotes that omit disposal/cleanup while still quoting low total prices.
Frequently asked questions — landscaping in London
How do I plan a low-maintenance yard?
For a low-maintenance yard in London, Ontario, design around the things that keep failing in our Zone 5b–6a winters: drainage, compacted bases, and plant choices that tolerate freeze-thaw. Start with fewer, larger maintenance zones: mulch shrub borders and groundcovers usually beat scattered small beds. Choose native-leaning perennials and shrubs that don’t need constant deadheading, and use thicker mulch layers to suppress weeds and buffer soil temperatures. For turf, match your grass strategy to your time—sod (often budgeted in the $2,500–$8,000 band depending on size) looks great quickly, but it still needs proper prep and first-season watering. If you have a low spot or clay pooling, a rain-garden style bed can reduce manual watering and help drainage. Finally, plan irrigation by zone (and add a controller with a rain sensor) so you’re not watering on a fixed schedule.
How deep should a retaining-wall base be for local frost?
In London, Ontario, freeze-thaw cycles and clay soils mean retaining-wall base prep is not something to guess. While wall designs vary by height and block system, a common best practice for stability is using a deep, compacted granular base—often in the 12–18 inch range for many interlocking block applications—plus the correct drainage provisions behind the wall (like a drainage layer and weeping/perforated drain where required). The goal is to keep water from saturating the backfill and to reduce lateral pressure that increases during thaw/freeze. If your wall is near the common 1.0 m (3.3 ft) threshold seen in Ontario municipalities, expect stricter requirements and possibly engineered drawings. Your contractor should state the base depth and drainage details in writing so you can compare quotes apples-to-apples.
How much does professional landscape design cost?
Professional landscape design in London typically lands within the overall “design & installation” budget range, often roughly $5,000–$30,000 for a full-service project when design is bundled with the build. If you’re only hiring design without installation, many homeowners still see design as a portion of the total scope because designers spend time on site grading review, plant selection for Zone 5b–6a, and drainage considerations. Since London has a roughly five-month main working season (early May through mid-October, planning around last and first frost), a good plan prevents rework when weather changes. Given that 52.3% of homes in the area are older (built before 1981), designers often account for foundation drainage patterns and legacy grading—work that can affect the final price more than the “look” of the plan.
How do I compare landscaping quotes?
To compare landscaping quotes in London, don’t just compare totals—compare what’s included. Ask each contractor for an itemised breakdown that separates labour and materials, including base prep depth, geotextile, compaction method, edging, disposal/hauling, drainage beds (if needed), and irrigation provisions. Confirm whether permits are included where applicable (for example, retaining walls above the typical 1.0 m threshold often require permits in Ontario). Make sure the scope lists what’s excluded—soil import, topsoil depth, stump grinding, and cleanup—because those omissions can swing costs significantly. Also check payment schedules (a deposit beyond 10–15% is a common concern) and warranties. As a quick sanity check, if one quote includes major drainage and interlocking with enough excavation, it should generally align with the local hardscape/retaining band of $4,000–$35,000 for many typical projects, while lawn-only scopes should land near turf bands such as $2,500–$8,000 for sod.
How long does a landscaping project take in London?
In London, Ontario, timelines depend heavily on excavation complexity, weather windows, and how many trades are involved. Many plant-and-mulch refreshes can be done in a day or two, but anything involving grading, drainage, or retaining walls takes longer because base preparation and compaction need proper sequencing. Sod and seeding also have time-sensitive establishment requirements around last frost and summer heat, so crews plan around the roughly five-month main working season. Interlocking patios usually take a few days to a week depending on thickness of base prep, drying/setting time, and how much regrading is required. A full design-and-install project can be multiple weeks because plants are sourced, hardscape is built, then planting happens after the final grades are locked in. Your best move is to ask for a written start date and completion estimate tied to specific tasks (excavation, base build, paver set, jointing, planting, final cleanup).
What is the best grass type for a London lawn?
For a London, Ontario lawn, the “best” grass is typically a cool-season turf that handles our winters and spring/fall frosts well. Most homeowners do best with blends commonly used for Southwestern Ontario that tolerate cold and recover from traffic. Sod is often chosen for fast results and uniform colour, while seeding is used when you want a lower-cost route and have time for establishment. If you’re comparing options, remember that sod installation commonly sits around $2,500–$8,000 depending on size and soil prep, while seeding can be more economical when the grade and topdressing are done properly. The most important factor isn’t only the seed or sod type—it’s drainage and soil depth. If you have clay-heavy pooling or poor airflow near foundations, the grass will struggle no matter the variety. A contractor should test drainage at minimum and correct grade so water moves away from your home.
