Here is the truth most homeowners learn too late: with interlocking and hardscaping, the contractor matters more than the pavers. The exact same stone can last 30 years or sink in three, and the difference is entirely in how the base is built and who builds it. If you are hiring a hardscape contractor in Mississauga or the GTA, here is how to choose one you can trust, and the red flags that should send you running.
Why the contractor matters most
Hardscaping is a below the surface trade. The part you see, the pavers, is maybe a third of the job. The base, grading, drainage, and edge restraints under them decide whether the project survives Ontario winters. Two crews can quote the same patio, and the one that digs deeper, compacts properly, and manages water will outlast the other by decades. That is why choosing the right contractor is the most important decision you will make.
Understand the base, the number one thing
Before you hire anyone, learn what a proper base looks like so you can tell who is cutting corners. For a GTA driveway, that means excavating and installing 8 to 12 inches of compacted gravel base, proper grading to move water away, and solid edge restraints to keep pavers from spreading. Patios and walkways need the same care, scaled to the use. If a contractor cannot clearly explain their base, that is your answer.
| Element | A proper install | A cut rate install |
|---|---|---|
| Base depth | 8 – 12 in compacted gravel | 2 – 4 in or bare soil |
| Compaction | Machine compacted in layers | Skipped or rushed |
| Drainage | Graded to shed water | Ignored |
| Edges | Solid edge restraint | None, pavers spread |
Check insurance and credentials
Any hardscaping contractor on your property should carry liability insurance and WSIB coverage for their crew. This protects you if something is damaged or a worker is injured. Ask for proof before work begins. A professional will have it ready. Anyone who dodges the question is telling you something.
Look at real, local projects
Photos are easy to borrow. Ask to see completed projects in Mississauga or the GTA, ideally in person or with addresses and references. Look for clean lines, tight joints, consistent borders, and work that has been in the ground a few winters. A contractor proud of their work will gladly show it off.
Get a detailed written quote
A real quote is itemized. It should spell out base depth, the specific pavers and brand, edge restraints, drainage, polymeric jointing, cleanup, and warranty. A one line number scribbled on a page is not a quote, it is a guess, and it leaves room for corners to be cut once the job starts.
Compare quotes fairly
The lowest number is rarely the best value. Line up the quotes side by side and compare what is actually included. A cheaper price almost always means a shallower base, skipped drainage, or lower grade materials. A slightly higher quote with a deep base and a real warranty will cost you far less over the life of the project.
Questions to ask before you sign
- How deep is the base, and how do you compact it?
- How do you handle grading and drainage on my lot?
- Are you insured and WSIB covered? Can I see proof?
- Can I see or speak with recent local clients?
- What brand and grade of paver are you using?
- What does your warranty cover, and for how long?
- Who is on site day to day, and who is my point of contact?
Red flags to avoid
- A quote far below everyone else
- No written contract or itemized scope
- Vague or missing base and drainage details
- No proof of insurance or WSIB
- Cash only pressure or a large up front deposit
- A rushed timeline that skips proper excavation
Warranty and timing
A confident contractor stands behind their work with a written workmanship warranty on top of the manufacturer paver warranty. On timing, the Ontario build season runs spring through late fall, and good crews book up fast, so plan early. A quality contractor being busy is usually a good sign, not a reason to rush to the cheapest available option.
Hiring FAQ
What should I look for?
Real local projects, proper insurance and WSIB, a detailed written quote, and a clear explanation of the base. In Ontario, the base decides everything.
What are the biggest red flags?
A suspiciously cheap quote, no written contract, vague base details, and no proof of insurance. Cheap almost always means a shallow base that fails within a few winters.
How do I compare quotes?
Compare what is included, base depth, materials, drainage, and warranty, not just the total. The lowest number usually leaves out what makes the work last.
The bottom line
The pavers get the attention, but the contractor and the base get the results. Choose a Mississauga or GTA hardscaping contractor who can prove their work, explain their base, show their insurance, and put it all in writing. That is how you get interlocking that still looks new after 20 Ontario winters.
