Eavestrough installation quality varies widely. Understanding what professional installation looks like helps homeowners evaluate quotes, supervise work, and recognize problems when they appear.
Hanger spacing determines structural integrity. Hangers should be placed every 60-90 cm (24-36 inches) to prevent sagging between support points. Eavestroughs installed with wide hanger spacing sag within a few years under snow and ice loading.
Planning Your Project
Slope must be continuous and consistent from each high point to each downspout. Slope of 6mm per 3 metres is appropriate. Professional installers measure and adjust slope before fastening — they don't rely on visual estimation.
Seamless construction eliminates midspan joints that leak over time. Seamless eavestroughs are formed from coiled aluminum on a machine brought to the job site — each run is formed to the exact required length in one piece.

Downspout placement must be at each low end of sloped runs. On long runs, intermediate downspouts prevent debris accumulation and water overflow. Adequate downspout count is a quality indicator.
Fascia fastening uses screws, not nails. Gutter spikes were standard in older installations but pull out of fascia as it ages. Hidden hanger systems with screws provide superior long-term fastening.
Sealant at inside and outside corners and at downspout outlets must be applied fully and without voids. Voids in corner sealant create the slow leak that stains fascia and siding over years before becoming obvious.
