How much does it cost to install a snow melt system on a deck in NB?

Snow melt systems are rarely installed on outdoor decks in New Brunswick, and for good reason — they're generally not a practical or cost-effective solution for NB's climate and deck construction.

Most deck builders and contractors in NB will steer you away from this idea, so it's worth understanding why before exploring your options.

Why Snow Melt Systems Don't Work Well on NB Decks

The core problem is that NB decks — whether pressure-treated, cedar, or composite — are built with gaps between boards to allow drainage and airflow. Electric radiant mats and hydronic tubing systems require a solid, continuous surface to function properly (think concrete driveways or tile floors). A slatted deck surface dissipates heat into the air rather than melting snow effectively, making the system largely inefficient and expensive to run.

NB's snow load is also significant — 250-300cm of annual snowfall. Running a system capable of keeping up with a heavy Maritime snowfall would require enormous energy draw, and the operating costs would be substantial given NB electricity rates.

What About Covered Decks or Screened Porches?

If you have a fully covered, enclosed deck or three-season room with a solid floor surface, the conversation changes slightly. In that context, electric radiant floor heating can be installed under composite or tile flooring — but this is really interior-style construction at that point, not a traditional open deck. Costs for electric radiant floor systems in that application run roughly $8-15/sq ft installed, plus ongoing electrical costs.

Practical Alternatives for NB Deck Owners

The more cost-effective approach most NB homeowners take is simply designing the deck to handle snow well and making removal easy. Composite decking (Trex, TimberTech) sheds snow more easily than wood and won't be damaged by shovelling with a plastic shovel. Some homeowners install a pergola or roof structure over part of the deck to reduce snow accumulation — pergola costs run $3,000-$15,000 depending on size and materials.

For the deck surface itself, keeping a quality plastic shovel on hand and applying an ice-melt product safe for your decking material (avoid rock salt on composite or cedar — use calcium chloride or a deck-safe product) is the standard NB approach.

When This Conversation Makes Sense

If you're building a new covered outdoor structure with a solid floor — essentially a three-season room or insulated porch — and want radiant heat, that's worth discussing with both a deck builder and an electrician. The electrical load requirements for radiant heat mean you'll need a licensed electrician involved regardless.
