Blocked gutters are one of the most common causes of damp in properties across London. Leaves, moss, and debris build up over time, the downpipe gets clogged, and water backs up and overflows. In winter, the standing water freezes, splits the gutter joints, and when it thaws you've got leaks as well as blockages. A proper gutter clean and repair sorts it all out — and it's one of the cheapest maintenance jobs you can do on your house.
Gutter repair and replacement covers everything from clearing blockages and resealing joints to replacing individual sections or installing a completely new system. The most common gutter material on properties across Enfield is uPVC — lightweight, affordable, and low maintenance, but the push-fit joints can leak after years of thermal expansion and contraction. We reseal these with proper gutter sealant and replace any sections that are cracked or warped. Brackets that have pulled away from the fascia — usually because the fascia board behind is softening with rot — need refixing to sound timber, or the fascia itself needs replacing. For period properties with cast iron guttering, we can either refurbish (cleaning back to bare metal, treating with rust converter, resealing joints with mastic, and repainting with metal paint) or replace with new uPVC or aluminium. Aluminium is a popular middle ground — it looks cleaner than uPVC, comes in a range of profiles and colours including heritage styles, and lasts 30+ years. We also install gutter guards and hedgehog-style leaf barriers for properties near trees, which dramatically reduce the frequency of blockages. For properties in Enfield, where a large borough in north London with diverse housing ranging from Georgian properties in Enfield Town to extensive inter-war and post-war suburban estates, guttering takes a lot of throughput from the roof above, and getting the right gutter profile and downpipe size is important for handling heavy rainfall without overflowing.
Leaves, moss, twigs, and general debris accumulate in gutter channels, especially near trees. The debris compacts over time and blocks the downpipe outlets. Water backs up, overflows the front or back of the gutter, and pours down the wall. In winter, blocked gutters freeze solid, putting strain on the brackets and potentially cracking the gutter sections. Regular cleaning — once or twice a year — prevents all of this.
uPVC gutters use push-fit rubber-sealed joints. Over years of expansion and contraction in hot and cold weather, the seals compress and lose their grip, and the joints start to drip. It's a slow leak that's easy to ignore until the water staining on the wall below tells you it's been going on for a while. Re-sealing with gutter mastic is a quick, inexpensive fix.
Gutters are held up by brackets screwed into the fascia board. If the fascia is softening with rot, the brackets pull out and the gutter sags, creating a low point where water pools instead of flowing towards the downpipe. This puts extra weight on the remaining brackets and the problem gets worse. Fixing a sagging gutter usually means replacing the fascia behind it as well as refixing the brackets.
Some properties across London have guttering that's too small for the roof area above — typically where a standard half-round profile was fitted to a large roof that really needs deep-flow or ogee guttering. The result is that gutters overflow during heavy rain even when they're clean. Upsizing the gutter profile and downpipes solves the problem permanently.
A gutter clean on a typical semi-detached in Enfield costs £80-£150 — that includes clearing all debris, flushing through the downpipes, and checking for leaks. Joint repairs on uPVC guttering run £100-£200 for a couple of problem areas. Replacing a section of damaged gutter is £50-£100 per metre. A full uPVC gutter replacement on a semi costs £600-£1,000 depending on the profile and number of downpipes. Aluminium guttering — which looks better and lasts longer — runs £1,200-£2,000 for a full replacement. Cast iron restoration starts from £1,500 for a small property and goes up depending on the condition. Gutter guards (mesh or hedgehog type) cost £8-£15 per metre fitted.
uPVC guttering: FloPlast, Brett Martin, and Polypipe — half-round, ogee, and deep-flow profiles in white, black, brown, grey, and anthracite. Aluminium guttering: AluStyle, Mustang, and Gutter Trade — available in any RAL colour, powder-coated for a durable finish. We also supply and fit heritage-style aluminium that replicates Victorian and Edwardian cast iron profiles. Cast iron: refurbished original sections or new from Hargreaves or Tuscan Foundry. Brackets: standard fascia brackets or rise-and-fall adjustable brackets for getting the fall right. Downpipes: matched to the gutter system in the same material and colour. Gutter guards: Hedgehog, GutterMate, and mesh-type guards.
We check all your gutters and downpipes in Enfield — clearing any blockages, identifying leaks, checking bracket fixings, and assessing the condition of each section. If the fascia board behind is soft, we'll let you know.
Based on the overall condition, we'll tell you whether repairs will sort the problem or whether replacement is the better investment. We explain our reasoning and give you a clear price for each option.
Whether it's resealing joints, replacing a section, refixing brackets, or installing a completely new gutter system, we work neatly and efficiently. New guttering is set to the correct fall so water flows towards the downpipes, not away from them.
We run water through the entire system to check for leaks and confirm proper flow. All debris is cleared from the ground and the work area is left tidy. If we've recommended gutter guards, we fit those as the last step.
Guttering across Enfield deals with a lot of water — the South East of England gets regular rainfall, and the roof area on a typical semi-detached funnels hundreds of litres through the gutters in every heavy shower. Enfield is a large borough in north London with diverse housing ranging from Georgian properties in Enfield Town to extensive inter-war and post-war suburban estates. Properties near mature trees — which is common in many residential areas of London — face a constant battle with leaf debris, especially in autumn. The most vulnerable are properties with standard half-round guttering that simply doesn't have the capacity for the roof area. Upgrading to deep-flow or ogee profile during a replacement makes a noticeable difference.
We don't just scoop out the leaves and move on. We check every joint, every bracket, every downpipe — and tell you about any problems we find so you can deal with them before they cause damage.
uPVC, aluminium, cast iron — we work with every guttering type across London. Whether you want a quick repair on existing uPVC or a full heritage-style aluminium upgrade, we can do it.
Gutters are only as good as the fascia holding them up. We always check the fascia condition and will tell you if it needs attention — no point fixing the gutters only for the fascia to fail.
If you're near trees and sick of cleaning gutters twice a year, we fit guard systems that keep debris out while letting water through. It pays for itself in avoided maintenance.
A gutter clean costs £80-£150 for a semi. Joint repairs are £100-£200. Section replacements are £50-£100 per metre. Full uPVC replacement on a semi is £600-£1,000. Aluminium runs £1,200-£2,000. We give you a clear price after we've had a look, and we explain what needs doing and why.
At least once a year — ideally in late autumn after the leaves have fallen. If you're near mature trees, twice a year is better (spring and autumn). Regular cleaning prevents blockages, leaks, and the damp problems that come from overflowing gutters. Or you can fit gutter guards, which reduce cleaning to every 2-3 years.
If the guttering is generally sound and you've just got a couple of leaking joints or a cracked section, repair is the obvious choice. If the system is old, joints are leaking everywhere, brackets are pulling out, and sections are warped or cracked throughout, replacement is more cost-effective. We'll give you an honest assessment.
For many homeowners, yes. Aluminium doesn't warp, crack, or discolour like uPVC can over time. It comes in a range of profiles and can be powder-coated to any colour. It lasts 30+ years with virtually no maintenance. The upfront cost is roughly double uPVC, but you won't be replacing it again.
If clean gutters still overflow in heavy rain, the gutter profile is probably too small for the roof area above. Standard half-round guttering handles about 40 litres per minute; deep-flow handles 60+. Large roofs or roofs with steep pitches can easily exceed the capacity of small gutters. The solution is upgrading to a larger gutter profile and matching downpipes.
Yes — cast iron can be refurbished by cleaning back to bare metal, treating with rust converter, resealing joints with Plumber's Mait or gutter mastic, and repainting with Hammerite or similar metal paint. The result looks great on period properties. Cast iron lasts almost indefinitely if maintained, so restoration is often the best approach for attractive original guttering.
Yes — modern mesh and brush-style guards keep leaves and large debris out of the gutter channel while allowing water to flow through. They don't make gutters completely maintenance-free, but they reduce cleaning from 1-2 times a year to once every 2-3 years. They're particularly worthwhile for properties surrounded by deciduous trees across London.
