Gutters do a quiet, thankless job until the day they stop, and by then the water is usually already finding its way into your brickwork. Knowing the difference between a gutter that needs a quick fix and one that is genuinely past saving can save you a much larger bill later. Here is how to tell which camp yours falls into.
A gutter should sit in a straight line with a gentle fall towards the downpipe. If you can see sections dipping in the middle, gaps opening up behind the fascia, or brackets that have pulled loose, the run is no longer draining properly. Water pools, adds weight, and the whole thing drops further.
The odd loose bracket can be refitted. But if a long stretch is sagging, or the fascia behind it has gone soft, you are usually better replacing the run than chasing repairs that will not hold.
Older properties around Shirley and West Wickham often still have the original metal or early plastic guttering. Rust streaks on metal, brittle cracking on plastic, or joints that have gone chalky and split are all signs the material has simply worn out. Once uPVC becomes brittle it cannot be reliably sealed again.
A single cracked joint might take a new union clip and a bit of sealant. Widespread cracking or rust along the length means the material has reached the end of its service life, which for uPVC tends to be around 20 to 25 years.
The clearest sign is what happens during a proper downpour. If water sheets over the front edge, or you see damp tide marks on the render and green algae growth down the wall, the gutter is not carrying the water away. Left alone this soaks into brickwork and eventually shows as damp inside.
Sometimes this is just a blockage from leaves and moss, which is a straightforward clear-out. If it overflows again soon after being cleared, the fall is wrong or the gutter has deformed, and replacement is the honest answer.
Gutters and fascias fail together. Peeling paint, flaking soffits, or timber that feels spongy when pressed usually mean water has been getting behind the gutter for a while. At that point replacing the gutter alone leaves the real problem in place.
It is worth doing both together while access is already set up. Combining new fascias, soffits, and guttering on a typical semi often works out more economical than two separate visits, and it stops the cycle of repairs on failing timber.
Modern uPVC guttering typically lasts around 20 to 25 years, while older cast iron can go much longer if kept painted. Exposure, tree cover, and how often it is cleared all affect the real lifespan.
Yes, if the rest of the run is sound and the profile still matches, a single length can be swapped. If the existing gutter is old, brittle, or discontinued, matching a section neatly is often not possible and a full replacement gives a better result.
It depends heavily on the length of run, the height, and whether fascias need doing too, but for a typical terraced or semi-detached home you are often looking at a few hundred pounds upwards. We always look at the job first and give a clear price rather than a guess.
