Time pressure
Water damage doubles every 30 min — speed matters
Burst pipes don't waitfor business hours
CMHC Quebec data shows 68% of residential water-damage claims originate from burst pipes between November and April. Most of those happen at night or on weekends — exactly when a solo plumber is asleep or with family.
A typical Montreal plumber gets ~40 weekend/overnight calls per month during winter. With personal-cell-only coverage, ~25% get answered live (10 calls), ~15% leave a voicemail that the plumber returns 6-12 hours later (by then the customer has Googled the next name and the next name was Mr. Rooter), and ~60% just hang up.
10 captured calls × 80% close rate × $520 average ticket = $4,160/month. The other 30 calls — 60% × 30 × 80% × $520 = $7,488/month — are lost to the next plumber on Google. Some of those losses are bilingual issues too: francophone customers who hit an English-only voicemail and immediately call someone else.
