Providing all rainwater solutions under one roof means you only need to deal with one company, making the process seamless. We offer an end to end solution including scaffolding, removal of old products, organising painters and builders, and much more.

We’re Local

We are proud to be New Zealand owned and operated. This means that clients can expect nothing less than first class Kiwi service and reliable products.


We take care of everything

We offer a comprehensive range of rainwater solutions, including fascia, spouting, roofing, and downpipes, making us a convenient one-stop-shop for customers in Manawatu and beyond.


Our expert team are proud to be the first and only supplier of Continuous Fascia in the Manawatu. With more than 15 years of experience installing this product, you can rest assured your property is in good hands.


Over the last 15 years, we have developed a premium range of quality Spouting solutions that have a strong focus on both functionality and aesthetics.


Your roof is an integral part of your home. Whether you’re after a professional repair, maintenance, re-roofing or something brand-new, we can help.


The last piece of the spouting system puzzle is Downpipes. Downpipes ensure that rainwater can easily flow into the stormwater system, preventing water from building up and damaging the roofs surface.
