About this range & buying advice
Master Plastics supplies a complete range of residential and commercial guttering systems for homes, extensions, industrial units, offices and larger developments. We offer professional guttering supply and fitting throughout Bristol and the surrounding area, together with supply-only delivery across the UK.
Homeowners, builders, roofers, installers, developers and trade customers are all welcome. From standard replacement guttering to high-capacity commercial systems, our team can help you choose the correct profile, material and capacity for the building.
Complete Guttering Range
We supply guttering for virtually every type of property, from small domestic extensions and garages to large commercial and industrial buildings. Our range includes popular everyday profiles as well as deeper, higher-capacity systems for larger roof areas and more demanding drainage requirements.
Guttering is available in a wide choice of profiles, materials, colours and sizes, with matching downpipes, outlets, bends, brackets, unions, stop ends and other fittings available to complete the installation.
Residential Guttering
Our domestic range includes half-round, square, ogee and deep-flow guttering for houses, porches, conservatories, garages and extensions. Choose from uPVC, aluminium, cast iron and steel systems to suit both modern and traditional properties.
Commercial Guttering
For larger roof areas, we supply high-capacity guttering designed to manage greater volumes of rainwater. Options include extra-deep, box, parapet and internal gutter systems suitable for commercial, industrial and development projects.
Guttering Profiles Available
The right gutter profile depends on the roof area, pitch, outlet position and expected water flow. Standard half-round and square systems suit many homes, while ogee and deep-flow profiles offer additional capacity and a more distinctive finish.
uPVC, Aluminium, Cast Iron and Steel Guttering
uPVC Guttering
uPVC is a cost-effective and low-maintenance choice for most domestic properties. It is lightweight, easy to install and available in a wide range of profiles and colours with matching fittings and downpipes.
Aluminium Guttering
Aluminium guttering provides a strong, durable and attractive finish for modern homes, commercial buildings and premium renovation projects. It offers excellent weather resistance and is available in different profiles and finishes.
Cast Iron and Steel Systems
Cast iron is ideal for heritage properties and buildings where a traditional appearance is important. Steel systems offer strength and high capacity for agricultural, industrial and commercial applications.
Supply and Fit in Bristol
Our Bristol fitting service can cover replacement guttering, new installations and complete roofline projects. We can assess the property, advise on the correct system and professionally install the guttering and downpipes.
Supply Only Across the UK
Trade and DIY customers can order guttering, downpipes and fittings for nationwide delivery. We can help identify compatible components and calculate the parts required for your project.
Trade customers are welcome. Contact us for project quantities, regular supply, commercial specifications or help matching an existing guttering system.
Guttering for Extensions, Homes and Commercial Buildings
Correctly sized guttering protects walls, roofs, foundations and surrounding ground from uncontrolled rainwater. A system that is too small, poorly positioned or incorrectly installed can overflow during heavy rainfall and lead to staining, damp and damage to the building.
Master Plastics has supplied roofline and rainwater products for more than 30 years. Whether you are replacing a short domestic run or specifying drainage for a large commercial roof, our experienced team can help you find a practical and competitively priced solution.
