Helical piles installation is becoming a worry-free solution in all kinds of residential builds. Are you building a deck, a garage, an extension, or even a house? No matter what kind of structure is needed, it all starts with a solid foundation. And if you’ve been doing your research, chances are you’ve come across helical piles.
In London, Ontario, they are known for being strong enough to support just about anything you’re building. But let’s be honest, what most homeowners really want to know is the cost.
- That’s exactly what this guide is here to answer. We break down the average cost of helical piles in 2025, what’s included in the price, what factors make your quote go up or down, and how to make sure you are getting the best deal.
What is the average cost of helical piles in London, Ontario in 2025?
While you are budgeting for a construction project in London, one of the first numbers you’ll want to lock down is the cost per helical pile.
In 2025, the average price ranges between 300$ and 600$ per pile, and that usually includes both the pile and the installation.
Most local contractors will quote around 500$ per unit, depending on the installer and project type. While 300$ is about as low as it gets, prices can easily go above $600 for more complex needs.
Helical pile | Minimum price | Average price | Maximum price |
Price per unit | 300$ | 500$ | 600$+ |
This pricing applies to standard residential installations, and it’s a good baseline if you’re estimating how many piles your project might require.
How much does helical piles installation cost in London?
The cost of installing helical piles includes labor, machinery, and the time it takes to complete the job. While the full price per pile ranges from 300$ to 600$, it’s useful to know that between 150$ to 350$ of that is for installation alone.
A significant portion is allocated to labor, not because the job takes days, but because it requires skilled individuals and the right equipment to ensure a safe, long-lasting foundation.
Even though the piles themselves aren’t overly expensive, it’s the expert handling and precise installation that drive the price. So, while you’re technically paying per unit, remember that each one includes not just the material, but the skilled work needed to get it into the ground properly.
How much does a pile foundation cost in London?

Installation price breakdown for a typical residential project in London, Ontario
To give you a clearer picture of costs, let’s look at a real example. John is building a medium-sized deck in London, Ontario.
- The structure requires about 10 helical piles.
- At an average price of 500$ per pile, the total comes to around 5 000$.
- This price includes both the piles and their professional installation.
- The crew takes a day to complete the work, using specialized equipment to ensure each pile is installed at the right depth and angle for a solid foundation.
This example reflects typical labor, machinery, and material costs you’ll find locally this year. Of course, bigger projects or challenging sites will increase the price, but for many homeowners, this gives a realistic range to plan from.
How do you estimate the cost of a pile foundation?
When you are not a professional, estimating the cost of a pile foundation is tricky, but one of the simplest and most reliable ways is the unit cost approach.
What is it? Basically, you figure out how many piles your project needs, then multiply that by the average cost per pile, including installation. This method works well because it breaks down the price into manageable chunks, making it easier to adjust your budget if your project changes.
So, how do you figure out how many piles your project needs? The exact number depends on several factors, like the size and weight of your structure, soil conditions, and local building codes. Usually, a structural engineer or a qualified installer will assess your site and plan to determine the right pile count and spacing.
For example, a small deck might only need 6 to 10 piles, while a larger home addition could require 20 or more. While you get a rough idea based on similar projects, it’s best to get a professional evaluation.
Helical piles installation - Is it a good long-term investment compared to other options?
Definitely yes! Here are a few reasons why installing helical piles is a really smart long-term investment:
- They resist soil movement and won’t crack or settle like traditional concrete footings.
- They’re installed faster, causing less disruption and lowering labor costs.
- Helical piles go deep below the frost line, avoiding damage from freezing and thawing cycles.
- Once installed, they require very little to no upkeep over the years.
- They work well in a variety of soil types and conditions, making them reliable for any project.
Because of these advantages, many homeowners agree that the higher upfront cost pays off through fewer repairs and a more stable foundation in the long run.
What factors influence the price of a helical piles foundation?
The price of a helical pile foundation isn’t set in stone. It will vary quite a bit depending on your project. While the cost per pile gives you a solid starting point, several factors affect the total price. Here’s what influences the price:
- Number of piles
- Pile size
- Load requirements
- Soil type
- Landscape features
- Permits and engineering
- Company you hire
Some of these are out of your control, but others, like comparing quotes, will help you save. That’s why it’s worth asking questions and making sure your estimate reflects the real conditions of your site.
What’s included in the installation price of helical piles?
When you get a quote for helical pile installation, it includes more than just the piles themselves. Most contractors in London offer a price that covers everything needed to get the job done properly including:
- Helical piles
- Professional labor for installation
- Specialized machinery and equipment
- Site preparation
- Installation to the required depth and torque
- Inspection or verification during installation
- Cleanup after the work is done
Keep in mind that engineering, permits, or custom site work may cost extra. Before signing anything, always double-check what’s included and what’s not.
What is the price difference between DIY and professional installation?
At first, doing it yourself might seem cheaper. A helical pile from the hardware store costs around 80$ to 120$ each, and you can rent the required machinery for 300$ to 500$ per day. Add to that your time, possible errors, and the lack of professional torque verification, and the savings start to fade.
On the other hand, professional installation costs more (300$ – 600$ per unit), but it provides you so much more:
- Peace of mind
- Code-compliant work (something DIY jobs often miss)
- Proper equipment and expertise
- Long-term reliability and cost saving
- Insurance and guarantee
So yes, let’s be real for a minute. While you will pay more upfront with a reliable company, you are getting quality, safety, and durability. In the end, it’s one of those cases where paying more is worth every penny.
