Winter — Moss Treatment in Guelph
Ontario freeze-thaw cycling is the single largest driver of masonry and water-entry failure in Guelph.
Masonry, waterproofing, and roofing all have hard temperature cut-offs — once overnight lows hold below freezing, the work waits for spring.
Booking in late summer costs 10-15% less than the November crunch and leaves time to fix what the inspection finds.
