Heated snow-melting driveways
Snow-melting radiant systems under patterned checkered interlock — engineered for Thornhill winters and long driveways, with smart sensors that activate automatically.
Serving Thornhill & the GTA
Heated driveways in Thornhill.
Thornhill winters are the worst kind for driveways: freeze-thaw cycles, sloped lots in the older neighbourhoods, and that 6 a.m. shovel before work. A heated driveway — heating elements under the surface that melt snow on contact — ends it. And because most Thornhill heated driveways go in during a full driveway rebuild, it’s the right moment to choose the surface too.
What we build in Thornhill
Our signature in Thornhill is the heated driveway — but we build the whole property:
Garden suites & tiny houses
Four models from about 480 to 800 sq ft with striking ACM facades — and we handle the building permit process from drawings to City approvals.
Landscaping & planting
Complete landscape design and installation: grading, sod, planting beds, garden walls and the finishing touches that make it look established.
Interlock driveways & walkways
Precision interlock with rich patterns and borders — including the checkered finishes we are known for — on a properly built base.
Heated snow-melting driveways
Radiant heating under your pavers melts snow on contact. No shoveling, no salt damage, a clear driveway all winter.
Pools & backyard design
From plunge pools to tropical lagoon concepts, designed as one complete backyard — pool, patio, deck and planting together.
What a heated driveway costs in Thornhill (2026)
Published GTA market ranges for a complete project — heating system plus the new driveway surface — run roughly $16–$37 per square foot installed in 2026, depending on system type and surface. For a standard 600 sq ft two-car driveway, that’s about $9,600–$22,200 all-in.
What Pisces charges: Our hydronic snow-melting system is $40 CAD per square foot (before HST) — that covers the boiler, tubing, manifolds, controls and system installation labour. Your finished surface is separate: concrete finishing is quoted as its own line, and interlock or other finishes are priced after a free site measurement, so your exact total is confirmed in writing before any work starts.
How that compares: Published GTA market ranges for complete heated-driveway projects run roughly $16–$37 per square foot for the heating system with a basic surface, with premium hydronic-under-paver work quoted higher by other GTA installers. Those ranges mix very different scopes — always ask any installer what is included (boiler? controls? surface? concrete finishing?) before comparing numbers.
What moves the number in Thornhill specifically
- Sloped driveways (common in older Thornhill streets) — heating is most worth it here; grading work may add cost.
- 100-amp electrical panels in older homes — electric systems may need a panel upgrade; hydronic avoids it.
- Surface choice — interlock pavers are the premium Thornhill finish (and our specialty); asphalt is the budget option.
- Existing driveway removal — old surface removal and disposal typically adds $2–$4 per sq ft.
Electric vs hydronic — which suits a Thornhill home?
Electric (cables/mats): cheaper to install; best for driveways under ~500 sq ft, walkways, and tire-track strips. May need a panel upgrade in older homes.
Hydronic (PEX tubing + glycol boiler): cheaper to run (natural gas), keeps working in a power outage, best for full 600+ sq ft driveways and sloped lots. Needs space for a boiler.
Rule of thumb: electric wins on install cost for smaller areas; hydronic wins on running cost for large ones — crossover around 400–600 sq ft.
Why Thornhill homeowners choose interlock + heat together
Pavers handle freeze-thaw better than poured concrete, individual stones can be lifted for repairs without tearing up the driveway, and the finished look matches Thornhill’s housing stock. The heating layer sits in the bedding below the pavers — invisible, automatic (snow sensor + thermostat), and salt-free, which adds years to the pavement’s life.
Who installs it — and who handles the permits
A heated driveway is multi-trade: Pisces builds the complete driveway — excavation, heating-layer installation, and the finished interlock surface — and coordinates licensed technicians for boiler and electrical connections (ESA electrical permit / gas boiler permit), because those legally require licensed trades. Before we dig, we call Ontario One Call for utility locates.
How to compare installers (ask every one of these)
- 1. Do you install both electric and hydronic, or only one?
- 2. Who handles the ESA electrical permit / gas boiler permit — you or me?
- 3. Is the heating work covered by a written workmanship warranty?
- 4. Can I see completed heated driveways you’ve actually built — photos of your own work?
- 5. What’s the drainage plan for the meltwater?
Frequently Asked Questions
How long does a heated driveway installation take in Thornhill?
Typically 5 days to 3 weeks, depending on size, system type, and whether the old driveway must be removed.
Will it melt a major snowstorm?
Systems are sized for typical GTA snowfall. In an extreme dump it keeps working through it — clearing just takes longer.
What happens in a power outage?
Electric systems stop until power returns; hydronic systems keep running on natural gas.
Do I need a permit?
The electrical or gas work needs permits and licensed trades — we coordinate that and it’s in the quote.
Is it worth it on a sloped Thornhill driveway?
That’s the strongest case for one: no ice on the slope, no salt damage, and the system works while you’re away.
