Guttering in Cumbernauld

On a terrace the gutter is one continuous run with a fall towards one or two downpipes, so a blockage or a sag outside one house makes water back up and overflow outside the next. That leads to a lot of arguments about whose problem it is. The honest answer is that it belongs to everyone the run serves. Where the block is still partly council-owned or has a factor, the factor or North Lanarkshire Council’s housing service usually arranges common repairs and bills each owner a share; where it is all privately owned, the owners have to agree between themselves, and under Scottish tenement law a majority decision on a necessary common repair binds the rest.

What we do in practice is survey the whole run, not just your bit, and give one written quote with each household’s share shown, so there is something concrete to put to the neighbours. If only you want to proceed we can clear or repair your own section, but we will tell you straight if the fault is really next door’s low point or a blocked shared downpipe, because there is no sense charging you for a fix that will not hold.

Many of Cumbernauld’s original new-town houses do not have an eaves gutter at all. The roof drains to an internal outlet, a chute through a parapet into a hopper, or a hidden parapet gutter behind a low wall, and then down a pipe you might never have noticed. These outlets block far more easily than an open gutter, because the whole roof’s moss, grit and leaves funnel into a hole a few inches across. When that happens the roof ponds, water finds the nearest joint or upstand, and the first you know is a stain on a bedroom ceiling.

We clear outlets, hoppers and parapet gutters as part of a gutter clean on these houses, fit leaf guards where they help, and check that the felt, EPDM or GRP around the outlet is still sealed. If the covering itself is failing, that is a job for our flat roofing service in Cumbernauld, and we will tell you rather than pretend a clear has fixed a worn-out roof. The same applies to the fascias and soffits in Cumbernauld behind an eaves gutter: on a flat-roofed block the timber edge is often the first thing to rot, and new brackets will not hold in it.

There are fewer big trees on Cumbernauld’s estates than in an old town, so the gutter filler here is moss. The concrete tiles on the pitched estates and the grit on the flat roofs both grow it, the hilltop wind and rain break it off, and it packs down in the gutter into a wet mat that does not flush through on its own. North-facing slopes and shaded courtyards are worst. Our advice for Cumbernauld is a clear every autumn without fail, a second every spring on north-facing or flat roofs, and a look after any storm, when the wind has usually stripped a fresh layer off the roof and into the gutter. If you are seeing water sheet over the edge in rain, drips from a union after the rain has stopped, or a green stripe on the render, it is overdue.

Damp in Cumbernauld houses gets blamed on flat roofs, on the 1960s construction and on condensation, and sometimes those are right. But a patch high on an outside wall, in the corner of an upstairs room or spreading down from the ceiling edge, is penetrating damp from above, and nine times out of ten it lines up with an overflowing gutter, a blocked outlet or a leaking downpipe on the other side of the wall. Rising damp never gets that high; it stays within about a metre of the floor downstairs. A streak on the outside wall below a joint, or algae under the eaves, confirms it.

Sort the gutter and the wall dries over a season. If the marks are already showing, our damp and water ingress service in Cumbernauld finds the route before anyone redecorates, and our article on how blocked and leaking gutters cause damp explains the signs to watch for.

Long terrace runs served by one downpipe need more capacity than a single semi, so on a Cumbernauld terrace we often fit a deep-flow profile, which carries considerably more water than standard half-round, or add a downpipe so no outlet is asked to drain more than 10 to 12 metres. Square-line uPVC matches the look of the 1960s and 70s houses and takes a fascia bracket well. On the exposed hilltop, seamless aluminium formed on site in continuous lengths avoids the unions that fail in wind and frost, and it suits the long straight runs here better than almost anywhere else we work. Some original runs on the oldest blocks are asbestos-cement; we handle and dispose of those correctly rather than breaking them up. Every downpipe should reach a gully connected to a surface-water drain or a soakaway, not the path; adding rainwater to a combined sewer needs Scottish Water’s agreement, which is rarely given for a house, so we work with the drainage that exists.

On access, we use ladders with stand-offs on straightforward two-storey work, a tower on long runs and stepped blocks, and scaffold where a parapet or a three-storey elevation needs it, and we price it on the quote. Nobody expects you to be up a ladder, least of all us. The same approach and prices apply across the Forth Valley; see our guttering in Falkirk page for the full breakdown.
