Installing a backyard pool is exciting — but one of the first questions homeowners ask is: “How long will this take from start to finish?”
The answer depends on a few key factors, including the type of pool you choose, weather conditions, permit approvals, and site access. In the London, Ontario area, most pool projects take several weeks from excavation to first swim — but not all pools follow the same timeline.
Let’s look at how long it typically takes to install the two most popular pool types: vinyl liner inground pools and fibreglass pools.
Factors That Affect Pool Installation Time
Before breaking down timelines, it’s important to understand what can influence the schedule:
Municipal permits and approvals
Engineered drainage plans
Weather and soil conditions
Property access and excavation challenges
Utility locates and inspections
Custom features like stairs, lighting, or waterfalls
In London and surrounding communities, permits and inspections alone can add several days to a few weeks before digging even begins.
Fibreglass Pool Installation Timeline
Fibreglass pools are known for their fast installation because the shell is manufactured off-site and delivered as a single piece.
Typical timeline:
1–2 weeks for the pool structure installation
(once permits and site prep are complete)
This includes:
Excavation
Setting the fibreglass shell
Plumbing and basic equipment installation
Backfilling around the pool
Initial water fill
Once the pool is in, additional time is needed for:
Electrical work
Decking or patio installation
Fencing and final inspections
Total project timeline:
Usually 2–4 weeks, depending on weather and patio work.
Vinyl Liner Inground Pool Installation Timeline
Vinyl liner pools are highly customizable in size and shape, but they require more on-site construction than fibreglass pools.
Typical timeline:
2–3 weeks for the pool structure installation
This includes:
Excavation
Steel wall installation
Base preparation
Plumbing and equipment installation
Liner installation and water fill
Additional work will extend the project timeline, such as:
Concrete, interlock, or patio installation
Electrical and gas connections
Fence installation and inspections
Total project timeline:
Usually 3–6 weeks, depending on complexity and weather.
How Weather Affects Pool Installation in Ontario
Ontario weather plays a big role in scheduling. Heavy rain can delay excavation and base preparation, and cooler spring temperatures can affect liner installation.
The busiest pool construction season in London is typically late spring through summer, which can also impact timelines. Booking early and completing permits in advance can help avoid delays.
From Dig Day to Swim Day: What to Expect
While the pool structure may only take a couple of weeks, homeowners should remember that a full backyard transformation includes:
Pool installation
Patio or deck construction
Fencing and safety barriers
Electrical and gas connections
Final inspections
A realistic expectation for most projects in the London area is 3–6 weeks. These timelines assume permits and materials are already in place.
