Most preventive maintenance schedules available online were written for milder, drier climates. They will tell you to service the heating system annually and clean the gutters twice a year, which is fine as far as it goes, and they will say nothing about the three forces that actually determine building longevity in Atlantic Canada.
Those forces are freeze-thaw cycling, salt air, and wind-driven rain. A schedule that does not account for them will leave you surprised by failures that were entirely predictable.
The Three Local Stresses
Freeze-thaw cycling
The Maritimes do not simply get cold. They oscillate around the freezing point repeatedly through the winter, sometimes several times in a week. Water gets into a small gap, freezes, expands, widens the gap, thaws, and goes deeper. Repeat fifty times a season.
This is why small cracks in foundations, masonry, asphalt and caulking grow so much faster here than the material specifications suggest. Every unsealed gap is a crack under construction.
Salt air
Coastal properties, which in the Maritimes means a large share of the housing stock, are subject to constant salt deposition. Metal corrodes faster, painted surfaces fail sooner, fasteners degrade, and exterior mechanical equipment — heat pumps especially — has a materially shorter service life than the manufacturer’s general figure.
Wind-driven rain
Water arriving horizontally at speed defeats assemblies that handle vertical rain without difficulty. Window and door flashing, siding laps and roof edges are the failure points, and the resulting leaks appear at interior locations well away from the actual entry point, which is why they are so often misdiagnosed.
A Calendar That Fits the Climate
Spring, April and May
The assessment season. Winter has just finished revealing every weakness.
- Full exterior inspection for freeze-thaw damage: foundation cracks, masonry, walkway and driveway heaving, step and porch settlement.
- Roof inspection, with attention to the eaves where ice dams form. Look for lifted or missing shingles and damaged flashing.
- Rinse salt from exterior equipment, metal railings, light fixtures and siding on coastal properties. This is not cosmetic; it is the main thing you can do about corrosion.
- Gutter cleaning and downspout check after winter debris.
- Reopen and test exterior hose bibs, checking for splits that occurred over winter but have not yet been noticed.
- Cooling system service, before the season and before contractors are busy.
- Caulking and sealant inspection at windows, doors and penetrations. Spring is the right time to reseal, because the material will cure properly and you are ahead of summer rain.
- Grading check. Confirm soil still slopes away from the foundation. Frost heave moves grade, every year.
Summer, June through August
The work season. This is when anything requiring dry, warm conditions gets done.
- Exterior painting, staining and siding repair.
- Roof repairs identified in spring. Do not carry a known roof defect into autumn.
- Paving and concrete work.
- Major projects requiring open walls or exterior access.
- Window and door replacement.
- Tree and vegetation management, including clearing branches away from roofs and power drops before storm season.
- Deck and railing inspection and repair.
Autumn, September and October
The protection season, and the most consequential six weeks of the year. This is the fall walkthrough: hose bibs shut and drained, gutters cleared, weatherstripping replaced, heating serviced, alarms tested, exposed pipes insulated, foundation vents closed, exterior lighting checked, snow clearing arranged in writing.
Everything on that list is cheap in October and expensive in January. The constraint is the calendar, not the budget.
Winter, November through March
Monitoring rather than working. Cold and ice make most maintenance impractical, so the task is watching for developing problems.
- Watch for ice dam formation after thaw-freeze sequences, and address them before interior damage occurs.
- Monitor heating performance and fuel consumption. A sudden increase indicates a problem.
- Check vacant units regularly — heat on, no leaks, no freezing. Weekly is not excessive for a vacant unit in January.
- Keep snow and ice clear of exits, walkways and fire exits, and document that clearing occurred.
- Watch for condensation and moisture problems, which peak in winter when buildings are sealed and humidity has nowhere to go.
Storm Readiness as a Standing Item
Atlantic Canada gets post-tropical storms in late summer and autumn, and significant winter storms throughout. The preparation is the same either way, and it belongs in the calendar rather than in the forty-eight hours before landfall.
Trees trimmed back from structures and service drops. Loose exterior items secured or a plan for securing them. Drainage clear so that sudden volume has somewhere to go. Emergency contacts current and available offline. Tenants told in advance what to do and who to call if power or heat is lost. Generator fuel, if you have generators.
After any significant storm, inspect. Damage that is trivial to repair immediately becomes a leak by the next rainfall.
Component Life Is Shorter Here
When planning replacement reserves, discount manufacturer service life estimates for coastal exposure. Exterior mechanical equipment, fasteners, metal railings, exterior paint and asphalt all reach the end of their usable life faster in salt air than general figures suggest. A heat pump on an exposed coastal property will not match the same unit inland.
Build your reserve schedules on observed local life expectancy — ask your contractors what they actually see — rather than on the specification sheet. The specification sheet was not written for here.
Making the Calendar Real
A schedule that exists in a document is not a schedule. Put the seasonal blocks in the actual calendar, with the checklist attached and the time booked, a season ahead. The fall block in particular should be scheduled in August, because by late September the contractors you want are already committed.
The portfolios that come through winter cheaply are not the ones with newer buildings. They are the ones where somebody did the October work in October.
