ALL ALUMASC CAST IRON GUTTERS · COMMON QUESTIONS

Something not answered here? The technical desk takes calls on 0330 0539354
What bracket types work best on mixed substrates?
Use fascia brackets for timber fascias, top-fix rafter brackets for exposed rafters, and rise-and-fall drive-in spikes for uneven masonry or lime-rendered walls.
How do I set out to avoid ponding at joints and angles?
Run a string line, set outlets first, pull falls to 1:600 to 1:350, then double-bracket either side of joints and angles so the joint doesn’t sit mid-span.
What joint hardware is supplied and how is it used?
Most lengths and fittings are pre-drilled. Insert sealant in the socket, assemble spigot-to-socket, then clamp with M6 x 25 mm bolts and washers with the mushroom head inside the gutter. Wipe squeeze-out for a clean finish.
What standards and finishes do Alumasc cast iron rainwater products comply with?
All Alumasc Apex Heritage cast iron gutters, downpipes and fittings are manufactured to BS 460:2002 for cast iron rainwater goods and supplied either factory primed or with a high-performance two-pack painted finish. Factory finishes are certified for long-term protection and colour consistency.
What are the typical lengths, bracket centres and falls for installation?
Most gutters and downpipes are supplied in 1.83 m (6 ft) lengths. Gutters are typically bracketed at 915 mm centres with extra brackets either side of joints, outlets and angles, and set to a fall of roughly 1:600 to 1:350.
How are joints made and sealed on site?
Traditional spigot-into-socket joints are made using a low-modulus silicone or rubberised bitumen mastic, then bolted through the pre-drilled joint holes using corrosion-resistant bolts and washers.
What about durability, repainting and lifecycle?
Cast iron is extremely strong, vandal-resistant and dimensionally stable. Life expectancy is typically 40+ years with correct installation and periodic maintenance. Factory-painted finishes minimise site time; primed goods can be site painted to the required scheme.
Are Alumasc cast iron systems suitable for heritage and sustainable projects?
Yes. They are widely used on listed and conservation properties because they replicate traditional profiles and details, and cast iron is 100% recyclable at end of life.
