Spouting & Gutter Specialists in Nelson

New spouting installation in New Zealand costs $30 to $60 per linear metre for Colorsteel or aluminium spouting, installed. A full spouting replacement for a standard three-bedroom home (approximately 40 to 60 linear metres) costs $2,000 to $4,500. Downpipe replacement costs $50 to $100 per downpipe. Gutter guard installation costs $25 to $50 per linear metre. Spouting repairs (resealing joints, fixing brackets) cost $150 to $400. Marley PVC spouting is the budget option at $20 to $35 per linear metre installed.

The main spouting types used in New Zealand are Colorsteel (pressed metal, colour-matched to your roof, 15 to 20 year life), aluminium (lightweight, corrosion-resistant, 20 to 30 year life), copper (premium, long-lasting but expensive), PVC (Marley brand, budget option, 10 to 15 year life), and continuous spouting (formed on-site in long lengths to minimise joins). Colorsteel and aluminium are the most popular choices. For coastal areas, aluminium or marine-grade Colorsteel is recommended due to salt corrosion.

Clean your spouting and gutters at least twice a year — in autumn after leaves fall and in spring. Blocked gutters cause water to overflow and run down the walls, causing damage to cladding, paint, and foundations. Remove leaves and debris by hand or with a gutter scoop. Flush with a hose to check for proper water flow and identify leaks. Check that downpipes are clear and directing water away from the foundations. Gutter guards reduce cleaning frequency but do not eliminate it.

Replace your spouting if it has significant rust or corrosion, leaks at multiple joints, sags or pulls away from the fascia, overflows during moderate rain (indicating insufficient capacity), or is visibly damaged or dented. If your spouting was installed with your original roof 20 or more years ago, it may be reaching the end of its life. Upgrading to modern continuous spouting reduces the number of joins and leak points.
