🪏 Digging Inquiries

Do you dig in my area?

We are based in Mississauga, Ontario but we cover most of the GTA (excluding downtown Toronto) and then some! From Niagara to Georgetown to Ajax, and everywhere in between, we’ve got your digging needs covered. Looking for post hole digging near me? Check out our service map here.  If your town isn’t on the list, hit us up – it doesn’t hurt to ask and you might be surprised how far we’ll go for you!

Do you dig on residential or commercial properties?

Yep, we work with everyone – from small residential backyard jobs to big commercial projects. No job’s too big or small for us!

How long does it take to complete a project?

Project timelines can vary depending on the job’s size and how complex it is. We’ll give you a rough timeframe when we’re quoting, and we always aim to meet those deadlines.

What kind of equipment do you use to dig holes?

We use mini skid steers with rubber tracks for digging, they’re designed to fit through gates that are at least 34 inches wide and are easier on the lawn than the wheeled ones.

Do you use two-man augers for tight spots?

We don’t use two or one-man augers in tight spots, because safety is our priority, and they’re not always the best for tough conditions like hard ground or roots.

Our mini skid steers are pretty compact, needing just 34 inches of space (less than 3 feet!). We usually fit through most gates, but if you have a tricky situation, just give us a shout!

Give us a call at (905) 497-4653, and we’ll see what we can do.

What's the alternative for digging in tight spots?

When mini skid steer machines just won’t fit, we offer manual digging with shovels and pry bars. The cost depends on how tough the digging is and what the project needs.

Will your equipment harm my lawn?

Our equipment has rubber tracks, so it’s designed to be easy on your lawn. It weighs over 1,500 lbs, but it’s usually safe, as long as the ground isn’t too wet or muddy. If you’re worried about your lawn, just let us know ahead of time.

How deep should post holes be?

For standard fences (up to 7 feet), we dig post holes 3 1/2 feet deep to avoid frost heave, which is a big deal here in southern Ontario. Taller fences need wider, deeper holes to stay put. For decks, pergolas, gazebos, and anything else that needs serious support, we put footings in at least 4 feet down, or even deeper depending on the project. If you want the nitty-gritty on post and pier depths around here, check out our blogs: Understanding Fence Post Depths and Understanding Deck Footing Depths.

Can I start building right away?

We usually say to wait 24-48 hours (depending on the weather) before building a fence. For footings, we recommend waiting 48-72 hours (longer if it’s cold). Our pros will check things out on-site and might adjust the wait time. If you need things done fast, we can use quick-setting concrete for an extra cost, getting you built in as little as 3 hours. Just let us know when you book so we can get everything set up!

Do you offer fence post removal and fence repair services?

Yeah, we can fix up your fence! Our repair service helps extend its life without a total rebuild. We’ll dig out the old posts and concrete, redo the holes the right way, and put in new posts with fresh concrete. We can also take off and rehang your fence panels and gates. It’s a budget-friendly way to make your fence stronger with long-lasting posts, so you can put off a full replacement and keep it solid. Plus, you won’t need new holes when you do want to rebuild. Save some cash and time while keeping your fence in good shape. Give us a call for a quote: (905) 497-4653

Is The Post Hole Company licensed and insured?

Yes, we’ve got Liability and Commercial Vehicle Insurance covered, plus we’re registered with WSIB (Workers Safety Insurance Board) and have Class A (Restricted) Driver’s Licenses. We’re also registered with CVOR (Commercial Vehicle Operator’s Registrant) and are good to go as HST registrants. And with 18 years of construction experience under our belts, you can trust your project is in good hands.

📐Post Sizing & Specs

What size post do I need for my fence?

For most residential privacy fences up to 6 feet tall, 4×4 posts are standard. If you’re building a 7-foot or taller fence, or using a heavier material like cedar, we recommend stepping up to 6×6 posts for added strength and longevity. We’re happy to advise on the right size when you call for a quote — just let us know your fence height and material.

What's the difference between a 4×4 and a 6×6 post hole?

The diameter of the hole depends on the post size. As a rule of thumb, your hole should be about 2 times the width of your post — so a 4×4 post gets roughly an 8-inch hole, and a 6×6 post gets a 12-inch hole. Bigger holes mean more concrete, which means a more stable, frost-resistant foundation. We size every hole correctly for your project.

How deep should a fence post should be in the ground?

Generally, one-third of the total post length should be buried. For a 6-foot above-ground fence, you’d want a minimum of a 10-foot post with roughly 3.5 feet in the ground — plus we dig to below the frost line (3.5 feet in southern Ontario) to prevent heaving.

Keep in mind, grade variances alters the required height of post in order to compensate for lower grade.  This too can be true for gate areas if you’re considering a decorative topper.

☝️REMEMBER: You can always cut back the post, but you can’t add height to a ‘too short’ post.

🪵 Concrete & Materials

What type of concrete do you use?

We mix our own concrete on-site using a secret blend of sand/stone to cement with controlled water ratios. This produces a strong, consistent mix that cures properly and holds up to Ontario’s freeze-thaw cycles — far more reliable than bag concrete dumped dry into the hole, which is a common shortcut used by others.

How long does concrete take to cure before I can build?

For fence posts, we recommend waiting 24–48 hours before attaching panels.

For deck footings and structural posts, 48–72 hours minimum — longer in cold weather.

If you need to build faster, ask us about quick-setting concrete options when you book.

Do I need to supply the concrete?

Nope — we supply all the concrete.

If you’re booking a “dig and set” package, just make sure your posts are delivered and on-site before our crew arrives. We can point you toward our preferred lumber suppliers if you need a recommendation.

❄️ Frost, Soil & Ontario Conditions

What is frost heave and how do you prevent it?

Frost heave happens when the ground freezes and expands, pushing posts upward — a very common problem in Ontario winters. We prevent it by digging below the frost line (minimum 3.5 feet in southern Ontario) and using properly mixed concrete.

What is the frost line depth in southern Ontario?

The frost line in southern Ontario is generally 2 and 1/2 feet, though for most residential fence posts, digging to 3.5 feet provides adequate protection. For deck footings and structural applications, we always go to the full 4-foot depth or deeper depending on soil conditions and local building codes.

Can you dig post holes in winter?

Yes — we operate pretty much year-round. As long as there is no snow on the ground and the roads aren’t slippery – we’ll get ‘er done!

Frozen ground is tougher to drill through and may require specialized equipment, which can affect pricing. Concrete also needs special care in cold temperatures (below 5°C) to cure properly. We use cold-weather concrete practices and can advise on scheduling based on the forecast. Call us and we’ll give you an honest assessment.

What happens if you hit rock while digging?<br />

Rocky soil is common in certain parts of the GTA, particularly in areas like Dundas, Flamborough, and parts of Halton like Guelph, Rockwood and Georgetown.

If we hit rock, we have a couple of options:

• We can adjust where the post hole gets drilled and hopefully miss the underground obstruction
• We can switch to a “rock-bit”and attempt to grind out the rock
• We can abandon the hole and provide a smart solution instead

We’ll always discuss the situation with you on-site and get your approval before proceeding with any change or added charge.

📍 The Scoop On Locates

What is Ontario 1 Call , and why is a Locate required for digging?

Ontario 1 Call locates underground utilities for safety. It’s a legal requirement for digging in Ontario. Locate requests help identify and mark gas, oil, power, phone, internet, water, and sewer lines. You need a response document from them before digging. We always check with them to ensure safe digging and avoid damage. Note: Ontario 1 Call doesn’t cover private lines (propane, pools, septic). Call us at (905) 497-4653 for a recommendation for private locator services.

How do I request a Locate?

We make things easy – you don’t even have to call Ontario 1 Call! We take care of everything, from getting the Locate Order done online to following up with Ontario One Call to make sure everything is on track for your appointment.

How long does it take for a Locate to be completed?

Ontario 1 Call usually gets locates done within 5 business days. But keep in mind, things can get backed up during the busy summer months (June to August). So, it’s a good idea to plan your project timeline with that in mind so you don’t run into any issues.

How long are Locates valid for?

Locates are typically valid for 60 days from the date they’re completed. If your project extends past this period or paint markings fade, a new locate needs to be requested.

Do I need Locates if I'm replacing an existing fence or re-using existing holes?

Yes, you still need locates, even if you’re just swapping out an old fence or using the same holes. Underground utilities can shift, or new lines get put in without your knowledge. Plus, locate clearance letters are only valid for 60 days. Getting current locates keeps everyone safe, avoids any mess-ups, and makes sure we’re following the rules.

Do I need Locates if the digging is only in the backyard?

Yep, you need a locate even for your backyard. Utilities could be anywhere on your property, so it’s important for safety and to follow the rules – get a locate done before you dig.

📄 Permits & Property Lines

Do I need a permit to build a fence in Ontario?

Nope, you don’t need a building permit for most residential fences.

In most cases, fences under 2 metres (6.5 feet) on residential properties don’t require a permit, but rules vary by city. Mississauga, Brampton, Oakville, and Toronto each have their own fence bylaws. We recommend checking with your local municipality before starting — and we’re happy to advise based on our experience working across the GTA.

Do I need a building permit for my deck project?

Most decks over 24 inches above grade require a building permit in Ontario. The permit process requires drawings showing footing depths and sizes, which must meet your municipality’s standards. We can dig your footings to permit specifications — just share your approved drawings with us and we’ll make sure everything is done to code.

How should I determine the starting and ending points for my fence?

To determine your fence’s start and end points, check registered land survey records for accurate property boundary details. Find them online at: Land Survey Records, through your realtor, or at your town hall. This ensures correct placement and avoids neighbor issues. Want more info? Check out our blog: Know Your Property Line.

📆 Payment, Bookings & Policies

How much does it cost to dig a post hole in Ontario?

Pricing depends on the number of holes, depth, soil conditions, and whether or not you need posts set in concrete. We offer transparent pricing — check out our Pricing Page for detailed rates. We don’t charge hidden fees, and you’ll know exactly what you’re paying before we show up.

Do you charge a travel fee?

Travel fees may apply for locations outside our core service area. We’ll always let you know upfront when you book — no surprises on your invoice.

Do I need to be home when you come to dig?

Yes — we do require someone to be present on-site for the duration of the job. Here’s why: digging conditions aren’t always predictable. If we encounter rock, roots, or other unexpected obstacles, we need to talk through the options with you in real time so we can make the right call for your project. We also collect payment on-site once the work is complete, so someone needs to be available to sign off and settle up when we’re done.

If the primary homeowner can’t be there, that’s fine — just make sure whoever is on-site has the authority to make decisions and can arrange payment. Give us a heads up when you book so we’re all on the same page.

How far in advance do I need to book?

It depends on whether you already have valid locates in place. Here’s how it breaks down:

No locates yet (most customers): Ontario 1 Call requires a minimum 5–10 business days to mark your property before we can dig — this applies year-round, not just in busy season. So factor that into your timeline when planning your project. The sooner you call us, the sooner we can get the locate request submitted and lock in your dig date.

Already have valid locates? If the markings are still visible on the ground and your locates are within the 60-day validity window, we can often get you in the same day, next day, or within the same week — depending on how many holes you need and your location.

Either way, call us at (905) 497-4653 and we’ll figure out the fastest path to getting you booked.

What are the payment terms for your digging-related services?

Booking a digging appointment is free, and you only pay when we’re done. To make things easy, our guys have payment terminals that take cash, all major cards, or debit cards. You’ll get a receipt right away.

How do I arrange building services with The Post Hole Company?

Getting our building services is super easy! Just give us a call to get the ball rolling. We’ll chat about your project and give you a price estimate over the phone and email. If you want to go ahead, there’s a small upfront travel fee, but it gets credited towards your project. That fee covers a visit from one of our pros to measure up and finalize the design and cost.
