Thornbury properties split into two maintenance problems: heritage homes near the harbour with original plumbing from the 1940s to 1960s, and custom builds at Lora Bay with mechanical rooms complex enough that one sensor cannot cover them. Cottage Care Company handles both from $59 a month for monitoring and $349 for full-service care, with multi-zone sensor layouts on the custom builds and freeze protection prioritised on the heritage stock. Coverage runs from the harbour through Lora Bay to Clarksburg and the Beaver Valley.
Monitoring from $59/mo. Full-service care from $349/mo.

Properties
About 3,500 permanent in Thornbury, plus roughly 600 homes at Lora Bay
Vacancy pattern
Active summer and fall through apple season. Midweek vacancy is the norm year-round.
The waterfront and harbour-side homes in Thornbury are frequently century properties on stone foundations, and a good number still run original plumbing installed somewhere between the 1940s and the 1960s. That plumbing does not fail more often than modern supply lines, but when it fails it fails worse, because the replacement parts are genuinely hard to source and a repair that would take a plumber an afternoon in a 2015 build turns into a week of waiting.
So the strategy on heritage stock is prevention weighted heavily over response. We alert at a higher temperature than we would on a new build, which means more callouts that turn out to be nothing, and that trade is correct here. A false alarm costs a drive. A burst 1950s supply line in a stone foundation costs the shoulder season.
Stone foundations bring their own moisture problem. They breathe, they wick, and a cottage that has been shut up since October will have a measurably damp lower level by March. We monitor humidity in the basement rather than assuming the main floor reading represents the building.
At the other end of the local stock are the custom waterfront builds, concentrated at Lora Bay but scattered along the shoreline. These have mechanical rooms with a boiler, a heat pump, sometimes geothermal, and a backup generator, all of which are separate systems that fail separately.
One sensor in a mechanical room tells you the mechanical room is cold. It does not tell you which of four systems stopped, and on a property where a failure produces six figure damage, that distinction is the whole point. Multi-zone monitoring is the standard we recommend on these builds, and we would rather lose the sale than install a single-sensor setup on a house with a seven figure replacement cost.
These properties also tend to carry insurance requirements that specify documented checks at a stated interval. The photo record matters more here than anywhere else we work, because the claim, when it comes, is large enough that the carrier will look closely at whether the policy conditions were met.
Clarksburg and the properties on the valley floor have a genuine microclimate problem that surprises owners who moved from the bay. Cold air drains downhill and pools on the valley floor on clear still nights, and a Clarksburg property can run five to seven degrees colder than a Thornbury property on the water at the same hour.
A monitoring threshold calibrated for the harbour is therefore wrong for the valley by a meaningful margin, and it is wrong in the direction that costs money: the alert fires late. We set valley properties separately, and on clear nights in the shoulder season that is often the difference between a call at midnight and a call at six in the morning.
Valley stock also skews toward converted mill buildings, farmhouses, and heritage properties on well and septic, so the rural failure modes apply on top of the temperature profile. Power goes out, the well pump stops, the septic stops, and the building has no water until someone attends.
| Risk | Window | What we do |
|---|---|---|
| Heritage plumbing failure with unsourceable parts | November to April | Freeze alerting set higher on heritage stock, accepting false positives to buy response time |
| Stone foundation moisture and lower level damp | October to April | Basement-level humidity monitoring rather than a single main floor reading |
| Multi-system mechanical failure in custom builds | Year-round | Multi-zone sensor layout so the alert names the failed system, not just the room |
| Beaver Valley cold sink on clear nights | October to May | Valley properties thresholded separately from bay properties, typically 5 to 7C apart |
Lora Bay is roughly 600 homes on the shoreline west of Thornbury, built around the golf club, and predominantly second homes. Use is year-round for members but concentrated into golf season from May to October and ski season from December to March, with midweek vacancy as the standing pattern rather than the exception.
The care requirement here is set by the buildings, not the calendar. Custom mechanical rooms with a boiler, a heat pump, and a generator need a sensor per zone, and the insurance policies on properties at this replacement cost generally specify documented checks. Our photo-documented inspections are built for exactly that requirement.
Lora Bay had its own page on this site until August 2026. It reads better as part of Thornbury, because it is the same route and the same crew, and because a Lora Bay owner searching for cottage care is well served by seeing the heritage and valley context alongside it. Discretion is part of the job here and we schedule around owners rather than through them.
Clarksburg is a small artisan village of roughly 500 permanent residents, ten minutes south of Thornbury harbour, with growing second-home activity and a property mix that runs from converted mill buildings to farmhouses to recent Beaver Valley builds. Peak use is ski season at the Beaver Valley Ski Club and the fall leaf season, which makes it quieter in summer than the coastal towns.
Two things drive the care plan: the cold sink described above, and the fact that heritage conversions have plumbing and electrical of unknown vintage behind the finishes. Our 30 point checklist is adjusted on these properties to spend more time on mechanical and less on exterior, because that is where the surprises live.
