Guttering in Grangemouth

When a Grangemouth gutter starts to sag or drip, the gutter itself is often not the problem. The plastic brackets on a uPVC system are fine, but the screws holding them to the fascia are usually plain or zinc-plated steel, and salt air gets through that coating in a few winters. Once the screw rusts, the bracket loosens, the gutter drops between brackets, the fall reverses and water pools at the low point until it finds a joint to leak through. On older runs with steel brackets, the brackets themselves rust through and the gutter simply falls away.

So when we repair guttering here we do not just re-seal the joint that is dripping. We check every bracket along the run, replace corroded fixings with stainless steel, re-set the fall towards the outlet and only then deal with the joint. On a full replacement we use stainless or coated fixings throughout, and we look at whether the fascia behind the bracket is still sound, because a rusted screw has usually let water into the board behind it. Where it has gone soft we would rather replace the fascias and soffits in Grangemouth at the same time than fix new gutter to a rotten board.

On a flat, low-lying site with a high water table, a soakaway does not always work, and many Grangemouth downpipes were designed to run into a gully connected to a surface-water drain instead. That arrangement is fine as long as the gully is clear. If it silts up, the downpipe backs up, the gutter overflows at the outlet even when it is perfectly clean, and the water ends up against your foundations. We check and clear the gully as part of every gutter job, and if the drain beyond it is blocked we will tell you so you can get it jetted.

Two general rules apply across Scotland. Rainwater should not be connected into the combined sewer without Scottish Water’s agreement, which is rarely given for a house, and a new soakaway under the Scottish building standards needs to be at least five metres from the house and the boundary, which many Grangemouth gardens cannot manage. In practice that means we work with the drainage your house already has, make sure every downpipe actually reaches it, and fit a shoe or a diverter rather than letting water splash onto the ground.

The good news about Grangemouth’s housing is that it is straightforward: two-storey semis, terraces and four-in-a-blocks with simple rooflines. The decision on any gutter is usually one of these three.

• Clean if the run is level, the joints hold once cleared and the plastic is not chalky or brittle. On estate houses with few trees, moss off the concrete tiles is the main filler, so once a year in late autumn is normally enough, with a second clear on north-facing roofs that never dry.
• Repair if one or two joints leak, a bracket has let go or a downpipe has parted at the offset, and the fixings are the cause rather than the gutter.
• Replace if the gutter has sagged in several places, has been patched with mastic more than once, or is the wrong size for the roof. On a four-in-a-block, replacing one owner’s section rarely works because the fall runs across the whole elevation, so we quote for the shared run and split the cost.

On wind-driven elevations facing the Forth we often suggest a deep-flow profile, which is noticeably wider than a standard half-round and catches rain that would otherwise overshoot. For those who want to stop re-sealing joints altogether, seamless aluminium formed on site in continuous lengths is the long-term answer, and it shrugs off salt in a way that steel fixings never will. Our guide to what new gutters and fascias cost goes through the price differences in detail.

Because the wind here drives rain onto the walls anyway, it is easy to blame the weather for a wet gable. The gutter usually gives itself away. A damp patch high in an upstairs room or a dark band on the render right under the eaves means water is coming over or behind the gutter above it; that is penetrating damp from the top of the wall, and it has nothing to do with rising damp, which only shows near the ground. A single streak running down beside a downpipe means a joint or the pipe has split, and green algae tells you it has been going on for a season or more.

Fix the gutter first and the wall dries. If the marks are already inside, our damp and water ingress service in Grangemouth traces the route the water is taking before anyone decorates over it. The same principles apply across the district; our Falkirk guttering page covers the full range of profiles and prices we work with.

Grangemouth is one of the windier places we work, and a two-storey ladder job on a sheltered street inland can need a tower on an open estate here. We decide the access at survey, price it on the quote and, on the worst days, reschedule rather than work in a gale. You will never be asked to go up a ladder to check anything for us. We photograph the gutters before and after and show you what came out, and if we spot lifted ridge tiles or loose verges while we are up, which is common after a Forth gale, we quote for those separately through our roof repairs in Grangemouth service so you can decide.
