It’s normally the small bits that get forgotten when ordering cast iron guttering. Our cast iron guttering sundries include the jointing components needed to finish an Alumasc Apex Heritage installation properly.
The Cast Iron Gutter Sealing Pack contains 10 preformed rubber seals with matching nuts and bolts. These are Alumasc’s Hydrostrip seals, designed for joining sections and fittings within the Plain Half Round cast iron guttering system. They can be used with the 100mm, 115mm, 125mm and 150mm Plain Half Round sizes.
Rather than forming every gutter joint with silicone, the rubber strip sits within the overlapping spigot-and-socket joint before it is bolted together. Alumasc developed the Hydrostrip system as a quicker and cleaner way of sealing its half round cast iron gutters, particularly useful when you have quite a few joints to make.
One thing worth knowing before ordering: Hydrostrip seals are not designed for Beaded Half Round, Victorian Ogee or Moulded cast iron gutters. Those profiles use the appropriate wet-sealed and bolted jointing method instead.
If you are putting together a complete system, browse our Plain Half Round Cast Iron Guttering alongside our cast iron downpipes and cast iron hoppers.

Popular black painted and primed cast iron products are usually available for next working day delivery when ordered before 11:30am, subject to stock. Custom RAL colours normally take around 7–10 working days.
For many UK homes, 115mm or 125mm guttering is a common choice. Smaller roof areas such as porches and outbuildings may use 100mm, while larger roofs or longer runs may need 150mm. Roof area, gutter profile and the number of outlets all matter, so it is worth checking before ordering.
Yes. We supply matching cast iron downpipes, hopper heads, brackets, outlets and fittings across the range, so you can put together a complete rainwater system rather than mixing different manufacturers or profiles.
Yes. Alongside painted black and primed finishes, many cast iron gutters, downpipes and hoppers can be supplied in custom RAL colours. Bespoke finishes are usually supplied within 7–10 working days.
Standard products can usually be returned within 30 days of delivery, although returns after the first 14 days may be subject to a restocking or handling charge. Made-to-order and custom-colour items are non-refundable, so it is worth checking sizes and finishes carefully before ordering.
Painted black products arrive with the finished colour already applied and are ready to install. Primed products are intended for projects where you want to apply the final decorative finish on site.
Normally, no. Plain Half Round, Beaded Half Round, Victorian Ogee, Moulded Ogee and Deepflow all use different shapes and fittings. It is best to keep the gutter lengths, unions, angles and outlets within the same profile and size.
Send us a photo and a few measurements. The overall width, depth, profile shape and downpipe diameter are usually enough to narrow it down and help identify the closest matching system.
You can buy individual components. We stock gutter lengths, unions, angles, stop ends, outlets, brackets, downpipes, bends, shoes, hopper heads and sundries separately, which is useful for repairs as well as complete installations.
Yes. If you have plans, elevations or even a marked-up sketch, send them over and we can help work through the likely gutter lengths, outlets, downpipes, angles and fittings required.
