New gutters eliminate the problem and protect your property for decades.

When they fail — through cracks, sagging, blockages, or misalignment — that water goes directly down your external walls, into your foundations, and eventually into your home. A typical UK roof collects around 50,000 litres of rainwater per year. Without functioning gutters, that water cascades down the brickwork, saturates the mortar joints, penetrates the masonry, and creates rising damp, penetrating damp, or both. The damage is gradual but relentless, and the repair costs far exceed the cost of new gutters. At AC Roofing & Carpentry Ltd, we replace guttering systems in uPVC, cast iron, and aluminium across North London. We work on terraced houses in Islington, Victorian semis in Hackney, period properties in Hampstead, and modern builds in Camden. Every installation is designed for the specific rainfall load and roof area of your property. We often combine gutter replacement with fascia and soffit work, which saves significantly on access costs. If your gutters are leaking, overflowing, sagging, or showing visible cracks, replacement is almost always more cost-effective than repeated repairs. Real Work ## See Our Gutter Replacement Projects ## The Damage Overflowing Gutters Cause to Your Property Water overflowing from gutters doesn't just make the walls wet — it initiates a cycle of damage that worsens with every rainfall. Saturated brickwork loses its thermal performance, making rooms colder and heating bills higher. Mortar joints soften and erode, allowing water deeper into the wall structure. In winter, trapped moisture freezes and expands, cracking bricks and accelerating decay. At ground level, water cascading from failed gutters pools around your foundations. Over months and years, this softens the subsoil and can lead to settlement — the kind of foundation movement that causes cracks in walls and requires underpinning costing tens of thousands of pounds. Internally, penetrating damp from failed gutters manifests as dark patches on walls, peeling wallpaper, musty smells, and mould growth. These aren't just cosmetic issues — damp and mould are recognised health hazards, particularly for children and people with respiratory conditions. The irony is that gutter replacement is one of the most affordable home maintenance tasks. A full set of new gutters for a terraced house costs a fraction of the damp treatment, replastering, and redecoration that result from ignoring the problem. How We Work ## Our Gutter Replacement Process 1 ### Survey We inspect the existing gutters, fascias, and downpipe runs for damage. 2 ### System Design We calculate the correct gutter size and downpipe positions for your roof area. 3 ### Removal Old gutters carefully removed, brackets extracted, and fascias inspected. 4 ### Installation New gutters fitted with correct fall, sealed joints, and secure brackets. 5 ### Water Test System tested with water to verify flow, drainage, and joint integrity. Why It Matters ## What New Gutters Protect ### Walls Stay Dry Properly functioning gutters prevent penetrating damp entirely. ### Foundation Protected Water directed to drains — not pooling at your foundations. ### No More Overflow Correctly sized gutters handle even heavy downpours without overflow. ### Maintenance Free Modern uPVC gutters don't rust, rot, or need painting. ### Combined Savings Replace gutters with fascias and soffits for one scaffolding cost. ### 30+ Year Lifespan Quality guttering systems last decades with minimal attention. ## Gutter Systems: Types, Sizing, and Selection ### uPVC Guttering uPVC is the most popular guttering material for residential properties. It's lightweight, corrosion-proof, easy to install, and available in multiple profiles (half-round, square, ogee, and deep-flow). Colours include white, black, brown, grey, and anthracite. uPVC guttering is connected with push-fit rubber-sealed joints that allow thermal expansion. Quality uPVC systems last 25–30 years with no maintenance beyond occasional cleaning. We use Marshall-Tufflex and FloPlast systems — both industry-standard brands with excellent track records. ### Cast Iron Guttering Cast iron guttering is the traditional choice for period properties, conservation areas, and listed buildings. It has a distinctive aesthetic that uPVC cannot replicate — heavier, deeper, with ornate brackets and profiles. Cast iron lasts 50+ years but requires periodic repainting to prevent rust. We supply and install cast iron gutters from manufacturers like J&R Hammond and Tuscan Foundry, available in traditional half-round and ogee profiles. For properties where heritage appearance matters, cast iron remains the right choice. ### Aluminium Guttering Aluminium sits between uPVC and cast iron — offering the lightweight, maintenance-free properties of plastic with a premium aesthetic closer to metal. Aluminium gutters are powder-coated in a range of colours, don't corrode, and have a lifespan of 40+ years. They're increasingly popular for contemporary properties and high-end renovations. Systems like AluStyle and Marley Alutec provide seamless options for runs up to 3 metres between joints. ### Sizing and Flow Calculations Correctly sizing gutters is essential. An undersized gutter overflows in heavy rain no matter how clean it is. We calculate the effective roof area (including wind-driven rain factors), determine the rainfall intensity for your location, and specify gutters and downpipes that can handle the flow. For most London terraced houses, standard 112mm half-round or 114mm square gutters are sufficient. Larger roofs or high-rainfall positions may need 150mm deep-flow gutters or additional downpipe outlets.
