The two weeks before closing is your last chance to install sensors before winter damage starts. This is a real question we get every week from Gravenhurst winterized cottage owners, so here is our fall 2026 take on it.
The hidden cost of an unchecked leak at a vacant cottage
Point-of-leak sensors are $80 to $150 each installed. A typical Gravenhurst winterized cottage needs 6 to 12 placed under sinks, behind the washing machine, near the water heater, and at the main supply. Whole-home shutoff systems (Phyn, Flo) run $1,500 to $3,500 installed.
A complete Gravenhurst leak monitoring package — sensors plus shutoff — typically lands at $2,500 to $4,500 installed. We can usually finish in a single day.
Sensor placement: under every sink, behind the washing machine, near the water heater
If you are reading this from Toronto and the cottage is 200km away, the install we just described is exactly what we built our service around. Gravenhurst is a 3-hour drive from the city. We handle the entire job without you being there, send you photos, and walk you through the new system over FaceTime before you head up for the weekend.
Whole-home shutoff vs point-of-leak sensors — what we install in Gravenhurst
The thing most Gravenhurst winterized cottage owners do not realize about this: the install typically takes 2 to 4 hours and we are in and out the same day. We bring the parts, the tools, and the experience. You do not need to be home if you have given us access in advance.
Cellular vs Wi-Fi: the connectivity problem at the lake
We install both point-of-leak sensors (sitting under a specific fixture) and whole-home flow monitors (on the main supply, learning your usage pattern). For most Gravenhurst winterized cottages, we recommend a hybrid: whole-home monitor at the main, plus 6 to 10 point-of-leak sensors at the highest-risk spots.
