The short answer
Continuous-run aluminium gutters are worth considering when you want a long, neat run with few joints and are happy to pay for a made-to-measure product. The gain is fewer joints to leak along the length. They do not cure a poor fall, weak brackets or a rotten fascia, and their cost depends on the length of run, the access and the fascia behind them, so the figure is confirmed only after the survey.
What a continuous-run aluminium gutter actually is
Most gutters arrive as short lengths, usually a couple of metres, that are clipped together with a joint at every connection. A continuous-run aluminium gutter is different. The installer forms it on site from a roll of coated aluminium, using a machine that shapes the channel to the length of your elevation. The result is one unbroken channel along each wall, joined only at corners, outlets and ends.
The trade label implies no joints at all, which is not quite so. Corners still need mitres, and stop ends and outlets still need fitting. Water can escape at any of them if the sealing is poor. What disappears is the string of mid-run joints that perish and weep on a conventional system.
Aluminium itself does not rot or rust in the way an iron gutter does, and it does not go brittle in the sun the way old plastic can. For the wider comparison of plastic, iron and aluminium, our guide to gutter materials for Stroud homes sets all three side by side.
Where the benefits are real
The strongest argument is fewer joints. On a long, plain elevation such as a terrace frontage or a rear extension wall, a conventional run can have a joint every few metres. Each joint depends on a rubber seal or sealant that sits in the weather and gets stretched by heat and frost. Take most of those joints away and a whole category of slow leak goes with them.
Appearance is the second argument. A single clean line along the eaves looks tidy, and the coated finish comes in a range of colours, which suits modern houses and some period ones where the owner wants a dark or neutral line. Because the run is cut to your measurements, there are no short offcuts or mismatched lengths.
The third is longevity. A single cleaning firm's blog, which we treat as low confidence, quotes about 20 to 30 years for aluminium against 10 to 20 for uPVC (Pureseal Services, December 2025). Sources on gutter life are thin and they disagree, so read that as a hint, not a guarantee. How long any gutter lasts depends on the fall, the fixing and how often it is cleared.
Where it falls short
A longer gutter is not automatically a better-draining one. A continuous channel still needs the right fall towards its outlet, and manufacturers typically recommend somewhere between about 1:600 and 1:350 depending on the system. Our answer on what fall a gutter should have explains how that works. Get the fall wrong and an unbroken run holds water along its whole length instead of at one joint.
Support matters just as much. A long, loaded aluminium channel wants closely spaced brackets, and the spacing is set by whichever system you buy. The detail is in our answer on how far apart gutter brackets should be.
Repair is less forgiving
If a conventional length cracks, you swap that one length. If a continuous run is dented or split, repair may mean cutting out and replacing a long section, or in the worst case a whole elevation. Matching the colour of coated aluminium years later can also be awkward. Impact damage from a ladder or a fallen branch is the usual cause.
Old boards and listed houses
New gutters hang from the fascia, so a soft or twisted board undermines any product. Older houses, particularly listed ones or those inside a conservation area, may need the council's agreement for the choice of material and profile, and aluminium is not always what the planning team wants to see in place of cast iron. Check with Stroud District Council's planning team before ordering.
What it costs and how to compare quotes
Continuous-run aluminium is made to measure, so its price is fixed in the quote. For a general guide, the figure that covers guttering of all kinds is this: MyBuilder's 2026 roofline price guide lists £30 to £70 per metre, with scaffold at £20 to £40 per m². That range covers common systems and is not specific to aluminium, so treat it as a floor for comparison rather than a price for a made-to-measure product.
Access often decides the total. On a two-storey house the scaffold or tower can cost as much as the gutter itself, and the job costs less if the fascia boards are renewed in the same visit. If boards are rotten, our answer on rotten fascia boards explains when they should be replaced first.
When you compare quotes, check that each of the following is covered:
- The product, its profile and its coating colour.
- The number of corners, outlets and stop ends.
- Fascia repairs or renewal.
- Scaffold or tower hire.
- Waste removal for the old guttering.
Following our survey you receive a written quote that draws on photographs of your own eaves, and it shows the VAT.
Deciding whether it suits your house
Continuous-run aluminium suits a house with long, uninterrupted gutter lines, sound fascias and an owner who wants fewer joints to watch. It suits less well a short or heavily broken roofline with many corners, since the saving comes from long lengths. It is a poor fit where the heritage case for cast iron is strong.
A fair way to decide is to start from the fault you are trying to fix. If you have joints that keep weeping, look first at the fall and the brackets. A joint that leaks because the run is sagging will leak again in the new system if the cause is left alone. Our answer on half-round, square and ogee profiles helps with the shape question once you have chosen the material.
Photographs of your eaves and fascia, sent by WhatsApp or the enquiry form, are enough for us to say where the job should start. Every job carries a written 10-year workmanship guarantee. The wider roofline range sits on our guttering, soffits and fascias page.
