How Moncton is built

Moncton's houses by when they were built Ten house shapes, one for each tenth of Moncton's 23,365 houses. Before 1961: 24%, 1961–1990: 37%, 1991–2000: 12%, 2001 or later: 28%. Older houses glow hotter.

Each house stands for one in ten of Moncton's 23,365 houses (single-detached, semi-detached, row and duplex), drawn by when it was built. The glow shows the usual pattern: older houses tend to be leakier and less insulated. More snow in the drawing means more heating degree-days: a longer, colder heating season.

Moncton at a glance

Climate

Moncton gets about 4,514 heating degree-days a year, a measure of how much heating its climate needs, and its winter design temperature, the cold day heating systems are sized for, is −22.1°C. Those figures come from the climate data for Moncton International in HOT2000, the home-energy software Natural Resources Canada (NRCan) gives energy advisors. A long heating season: air sealing and insulation pay back well, and every leak costs money for months.

Housing

Of Moncton's 23,365 houses (single-detached, semi-detached, row houses and duplexes), 24% were built before 1961 and 60% before 1991, according to the 2021 Census. The typical house dates from 1981–1990.

Heating

In the Moncton area, 34% of households heat mainly with electric baseboards; electricity is the main heating energy for 42% of households (Statistics Canada, 2023).

Radon

Health Canada's 2012 survey found 19.8% of 106 homes tested in the Region 1 health region above the guideline. The larger 2024 Cross-Canada survey reports 8.1% (1 in 12) of houses at or above the guideline for the Moncton, NB (Moncton CMA) metro area.

What homes in Moncton need

Damp, windy, icy winters and costly oil: switch to heat pumps, seal, test for radon.

Atlantic winters are wet, windy and icy rather than extremely cold, and summers are mild. Heating oil is still common and its price rose sharply in 2026, while heat pumps already heat many homes. An EnerGuide evaluation here should plan the move off oil, seal wind-driven leaks, fix moisture before insulating, and include a radon test.

In Moncton: Moncton has the highest mini-split use we cover: about 38% of area homes heat with one. Heavy snow loads and about 14.5 freezing-rain days a year make attic air sealing important, and about 1 in 4 New Brunswick homes tested high for radon.

What drives bills and comfort here

  • Wind drives heat out: damp, windy winters push cold air through gaps in the house, and freezing rain is frequent.
  • Oil still heats 28% of homes in Nova Scotia and PEI; heat pumps heat 31% in NS, about 41% in PEI and 48% in NB.
  • Heating oil jumped 65% to 81% in a year: by September 2026 it averaged about $2.00 to $2.60 a litre in Atlantic cities.
  • Electricity costs about 15.6¢/kWh in St. John's to 20.5¢ in Halifax (April 2025).

Local risks to plan for

  • About 14.5 days a year with freezing rain or drizzle.
  • About 2.3 days a year with wind gusts of 90 km/h or more.
  • The 2019 Saint John River flood closed the Trans-Canada Highway to Fredericton for seven days.
  • Radon: about 1 in 4 New Brunswick homes tested at or above the guideline in 2024.

What to check first, and why

  1. Plan your move off oil

    Oil prices rose 65% to 81% in a year, and corrosion is a leading cause of oil tank leaks. Cold-climate heat pumps can be up to three times as efficient as oil heating.

    Ask your energy advisor: Ask the advisor to note your oil tank's age and condition, and to size a cold-climate heat pump with a backup plan.

  2. Seal wind-driven leaks and the attic

    Wind pushes cold air through gaps, and heavy, wet snow with frequent freezing rain makes a leaky attic prone to ice dams.

    Ask your energy advisor: Ask for a blower door test on a calm day, with a thermal scan to find wind-driven leaks.

  3. Fix moisture before you insulate

    Halifax, St. John's, Saint John and Charlottetown get enough wind-driven rain that new walls must have a rainscreen. Stop water getting into walls and basements before adding insulation.

    Ask your energy advisor: Ask the advisor to check the basement, attic sheathing and walls under windows for damp, and how bath fans vent.

    Mould and humidity checkVentilation assessment

  4. Test for radon

    Atlantic Canada had the highest radon of any region in the 2024 national survey: about 1 in 3 homes at or above Health Canada's guideline, and more than 1 in 3 in Nova Scotia.

    Ask your energy advisor: Run a 3-month test in the heating season, and retest after air sealing or other upgrades.

  5. Plan for storms and power outages

    Dorian in 2019 affected 80% of Nova Scotia Power customers, and Fiona in 2022 cut power to over 600,000 homes and businesses. Keep backup heat until a heat pump has proven itself.

    Ask your energy advisor: Ask where the outdoor unit should sit to stay clear of drifting snow and ice, and how you'd heat during an outage.

Tests that matter most here

  • Blower door test Finds wind-driven leakage paths; a before-and-after test shows what sealing achieved. Best timing: December to March, on a calm day.
  • Infrared (thermal) scan Shows insulation gaps and air leaks. Best timing: December to March, on a calm, overcast day with at least 10°C between inside and outside.
  • Combustion safety test Checks that the oil burner and chimney vent safely, especially once air sealing changes indoor air pressure. Best timing: Before winter, and again after air sealing.
  • Ventilation assessment Damp air and heavy rain make moisture the main risk; this checks fans, indoor humidity and signs of mould. Best timing: Late fall or the spring wet season.
  • Radon test High regional radon. Best timing: At least 91 days in the heating season; retest after upgrades.

Upgrades that usually pay off here

  1. Cold-climate heat pump to replace oil or baseboards. Ductless mini-splits or a ducted system cut heating costs and add summer cooling. They're already common: mini-splits heat 38% of homes in the Moncton area. Keep the oil system or baseboards as backup until the heat pump has handled a cold snap and an outage.
  2. Air sealing plus attic insulation. Cuts wind-driven heat loss and helps prevent ice dams. Today's new-home attic minimum here is about R-49.
  3. Basement insulation after moisture control. Basements can be about 20% of heat loss; dry the basement first, then insulate.
  4. HRV for balanced ventilation. Removes winter moisture from a tighter house while recovering much of the heat.
  5. Replace a corroded oil tank, or remove it. Corrosion is a leading cause of tank leaks, and spill cleanups are expensive and can affect resale. If you keep oil, check the tank and lines for leaks after each fill.

Heating and cooling equipment

  • Use a cold-climate heat pump, and keep existing oil or electric baseboards as backup for cold snaps and outages.
  • If oil stays as backup, set its thermostat below the heat pump's so the heat pump does most of the work.
  • Choose demand-defrost controls, which NRCan says are generally more efficient than timed defrost.
  • An HRV usually suits damp coastal homes better than an ERV, which is suggested mainly for high cooling loads or dry indoor air.

Health and comfort

  • Radon is a major hidden health risk here: the 2024 survey found about 1 in 3 Atlantic homes at or above 200 Bq/m³, the highest of any region.
  • Damp and mould: run bath and kitchen fans, and keep winter relative humidity low enough to avoid condensation.
  • Carbon monoxide: install CO alarms near oil appliances or a wood stove, and in each bedroom area.
  • Wildfire can reach city edges: the June 2023 Tantallon fire destroyed about 150 homes in the Halifax area.

Common mistakes in this climate

  • Ignoring an old oil tank. Corrosion is a leading cause of leaks, and cleanups are expensive and can hurt resale.
  • Removing all backup heat too soon. Keep a backup until the heat pump has proven itself through a cold snap and a power outage.
  • Insulating a damp basement from the inside. Trapped moisture can rot new framing and feed mould. Fix water entry first.
  • Air sealing a damp house without ventilation. A tighter house holds more moisture; add fans or an HRV at the same time.

When to book: Book the evaluation from December to March, on a calm day, for the best blower door and thermal scan results. Have oil equipment checked before winter, and start a 3-month radon test in fall.
