GMG Roof Experts, the leading roofing company in London, offers top-tier roofing solutions tailored to your specific needs.
GMG Roof Experts repair, replace and clear guttering and downpipes across the whole London Borough of Hillingdon. We reseal leaking joints, re-set gutters that have dropped out of fall, refix loose brackets and outlets, clear blocked runs, hoppers and downpipes, and where a system is brittle or rusted through we strip it and fit a new one on the correct falls. uPVC, cast iron and cast-style aluminium, half-round, square and ogee, from one dripping joint over a doorway to a full re-run on a terrace, all from our Hayes UB3 base across Uxbridge, Hayes, Ruislip, Ickenham, Northwood and every postcode in between.
The background
Guttering has one job, to catch the water off the roof and take it down and away from the wall, and it usually fails quietly. On the Victorian and Edwardian terraces around Uxbridge, Yiewsley and Cowley, and on the 1930s semis in Ruislip and Ickenham, the first sign is a stain running down the render or brickwork below a joint, or water sheeting off the front edge in heavy rain rather than draining to the downpipe.
uPVC gutter goes brittle in the sun, the rubber seals in the joints harden and shrink, and the brackets work loose so the run sags and holds water instead of moving it. Cast iron rusts from the back where you cannot see it, the joints seize and crack, and the bolt fixings rot the fascia behind. Downpipes block with moss and silt washed down from the roof, or with leaves from a nearby tree, and back up at the shoe or the gully.
The judgement on any gutter is whether it can be resealed, re-set to fall and re-bracketed, or whether enough of it has gone that a new run is the better value. We give you that assessment straight, with a written quote either way, and we check the fascia and soffit behind the gutter at the same time because a new gutter is only as sound as what it is screwed to.
We are based in Hayes, we work on guttering across Hillingdon every week, and we have handled everything from a single leaking joint over a front door to a full re-run with new fascia on a terrace.
What we do
From one leaking joint to a full re-run with new fascia, every job below is carried out by our own team, not subcontracted out, and every one starts with a close-up inspection and a written quote on request.
Leaking joints, sagging runs, loose brackets and cracked sections. We trace where the water is actually escaping, not just the stain, and reseal, realign and refix rather than paper over it.
When uPVC has gone brittle or cast iron has rusted through, we strip the old run and fit a new system in the right material and profile, set out to fall to a proper outlet and downpipe.
Clearing moss, silt and leaves from gutters, hopper heads and downpipes, flushing the full run through to the gully and checking the water gets away where it should.
Blocked, split or detached downpipes, missing shoes and back-inlet gullies that have silted up. We rod the run clear, replace cracked pipe and re-clip it tight to the wall.
A new gutter is only as sound as the board it fixes to. Where the fascia or bargeboard behind the run has rotted, we renew or cap it in uPVC before the gutter goes back up.
For runs under trees that block every autumn, mesh or brush guards fitted over a gutter that has first been cleared and checked, so it keeps moving water instead of holding leaves.
A guttering repair starts with watching where the water actually goes, not guessing from the stain on the wall. We check the run in the rain where we can, or flush it through, and look at the joints, the brackets, the falls, the outlet and the fascia behind before agreeing a scope of work. A leak at a joint two metres away will still show as a stain over the door.
Once we can see the cause, we repair the way the run was built. That means new gaskets or union clips at the joints, lifting and re-bracketing the gutter back to a steady fall towards the outlet, replacing any cracked section in matching profile, and clearing the downpipe and gully so the water has somewhere to go. On a terrace near Uxbridge High Street we will check the neighbouring lengths at the same time, because a shared run fails as one.
How it works
The process is the same whether it is a single leaking joint or a full re-run, and it starts with a conversation, not a sales pitch.
Call 07949 999411 or use the contact form. Tell us where the water is showing, inside and out, and roughly where the property is in Hillingdon.
We get up to the run, flush it through, find the cause, and send a written quote covering material, access, labour and timescale, with repair and replacement options where both are realistic.
Most gutter work is done from a tower or ladder access, a full re-run on a two-storey terrace from a scaffold. We arrange the right access so the job is done safely and lasts.
We complete the agreed scope, test the run with water, clear up and take the old gutter away, and give you a written summary with photographs of the finished job.
Materials
Not every house needs the same gutter, and the right choice depends on what is already there, the look of the frontage and the budget. On a plain semi, uPVC in the matching profile is usually the sensible answer. On a period or conservation area frontage, cast iron or cast-style aluminium keeps the proportions right. Where a run is long, exposed or awkward to get back to, powder-coated aluminium is strong and holds its line. We match the profile, half-round, square or ogee, and the downpipe, round or square, to what the house already has.
We record the run and its falls before we touch it and set the new gutter out to the same line, matching the profile and colour so the front of the house still reads as one.
Lightweight, low maintenance and available in every common profile and colour. The sensible choice for most semis and post-war houses.
For period and conservation area frontages, traditional cast iron or a lighter cast-style aluminium that keeps the same deep profile and shadow line.
Powder-coated aluminium for long or exposed runs. Strong, holds its line, and available in half-round and moulded profiles.
Half-round, square and ogee gutter matched to the house, with round or square downpipes, hopper heads, swan necks and shoes to suit.
When uPVC has gone chalky and brittle, or cast iron has rusted from the back so the joints crack as soon as they are disturbed, repairs stop being worthwhile. Every reseal buys a season before the next joint goes, and the fascia behind has usually softened anyway. At that point a new run is the better value.
We take the old gutter down, check and renew the fascia or bargeboard where it has rotted, and fit a new system on fresh brackets set out to a steady fall towards the outlet. Downpipes are re-clipped tight to the wall on stand-offs, with new shoes into the gully, and the whole run is tested with water before we leave.
A gutter that overflows in every downpour is not always a gutter fault. Often the run is fine and the water simply cannot get away, because the outlet, the downpipe or the gully below it is blocked with moss, silt and leaves washed down off the roof.
We clear the gutter and hopper by hand, rod and flush the downpipe from the top, and clear and re-seat the back-inlet gully at the bottom so the whole path runs free. Where a downpipe keeps blocking at the same offset or swan neck, we look at whether the layout is the problem and put it right rather than clearing it again next year.
Completed work
Every image below is a real GMG Roof Experts photograph taken from the company's own site. Each one appears once, and the caption names the type of work where it could be confirmed from the source.
Guttering and downpipe work is a defined part of what we do from our Hayes base, inside the borough, from a single leaking joint to a full re-run with new fascia. That means we turn up with the right access, gutter matched by material and profile, and we do the diagnosis on the run and at the gully before quoting.
Our work runs from resealing joints and re-bracketing a sagging run to stripping tired uPVC or rusted cast iron and fitting a new system. We are CITB certified, fully insured, and work from scaffold, tower or ladder access as the job needs, we check the fascia behind every gutter, and every job ends with a written summary and photographs.

Questions
The questions below come up most often from Hillingdon homeowners, landlords and businesses.
Water sheeting off the front edge of the roof in heavy rain instead of draining to the downpipe, a green or black stain running down the wall below a joint, damp on the internal wall behind the gutter, and plants or grass growing in the run. A gutter that visibly sags between brackets is holding water and will leak at the next joint.
A single leaking joint on an otherwise sound uPVC run is usually a repair: a new gasket or union clip and, if needed, lifting the gutter back to a proper fall. Where the plastic has gone brittle across the run, or cast iron has rusted so the joints crack when disturbed, a new run is the better value. We tell you which it is after getting up to it, and quote both where both are realistic.
Not always. Often the gutter is fine and the water cannot get away because the outlet, the downpipe or the gully below is blocked with moss, silt and leaves off the roof. We clear the gutter and hopper by hand, rod and flush the downpipe, and clear the gully so the whole path runs free, then check whether the falls need adjusting as well.
Yes. We rod and flush downpipes from the top, clear hopper heads and back-inlet gullies, and re-clip any pipe that has come away from the wall. Where a downpipe keeps blocking at the same offset or swan neck we look at whether the layout is the real problem and put it right.
Yes. We identify the existing profile, half-round, square or ogee, and the downpipe type, and match a new run to it in uPVC, cast iron or cast-style aluminium so the frontage still reads as one. On a shared terrace run we will flag where the neighbouring lengths are likely to need the same work.
Yes, and often it is necessary. A gutter is only as sound as the board it fixes to, so where the fascia or bargeboard has rotted we renew or cap it in uPVC and fit vented soffits before the new gutter goes up. That work is set out separately in the written quote.
Most repairs and clearances are done from a tower or with ladder access. A full re-run on a two-storey terrace, or work over a conservatory or extension roof, usually needs a scaffold for safe access. The access method and its cost are set out in your written quote before any work starts.
Yes, for runs under trees that block every autumn. We clear and check the gutter first, then fit a mesh or brush guard matched to the profile, keeping the hopper heads and outlets accessible so the run can still be checked.
We inspect the run and the gully in person, then send a written quote covering material, access, labour and timescale. Where both a repair and a replacement are realistic, we quote both so the choice is yours. All pricing is on request after that visit, because access, the length of the run and the material are the biggest variables. We do not give figures without seeing the job.
