Who Fixes a Gutter Shared With a Neighbour?

Ownership of a gutter is a question of paperwork, not of which side the water seems to come from. On many semis and terraces the guttering is laid in one continuous line along the eaves, and a single downpipe at the party wall may take rain from both roofs. Nothing about that arrangement tells you who is responsible for it.

Start with your title deeds and the plan that came with them. Some deeds say that the owners share the cost of upkeep for anything serving both houses. Others say nothing at all, and then it comes down to who the damaged length belongs to and who benefits from it. We are roofers rather than solicitors, so we cannot settle a legal point for you. If the deeds are unclear and you disagree, a solicitor or Citizens Advice is the right place to ask.

It helps to know what you are dealing with before you knock on a door. A roofer can look at the run from a ladder or tower and tell you which lengths are cracked, which joints are leaking and whether the fault is on your side, on theirs or at the shared joint in between. That turns a vague row into a short, factual list.

Most disputes over a shared gutter are really disputes about the first conversation. A friendly, practical note works better than a demand: say what you have seen, say what is likely to happen if it is left, and offer to arrange the quote so your neighbour has nothing to organise.

Rain that spills over a failed gutter soaks the wall below, and on a shared wall that damp does not stop at the boundary. Both homes have a reason to want it dealt with. That is usually the point that gets people talking.

Be clear about access. Reaching the gutter on your neighbour's side of the run may mean ladders, a tower or scaffold standing on their path or in their garden, and that needs their agreement. Ask for it plainly and say how long the work will take. A roofer who explains each day's plan to both households makes this much easier. Put whatever you agree in a short message or letter, covering what is being done, who is arranging it and how the cost will be divided, so the arrangement does not depend on anyone's recollection.

If your neighbour will not engage, repair what is clearly yours and keep photos of the whole run as it was.

No fixed rule divides the bill between two houses, so neighbours settle it in whatever way feels fair to both. Three arrangements come up often. Some split the whole job in half, which is simple when both roofs are about the same size. Some divide it by the length of gutter each house uses. Some pay for the faulty sections on their own side and share only the cost of access and the joint between.

For a rough guide to the size of the bill, In Checkatrade's October 2026 gutter replacement table, 15 to 20 metres of guttering with three downpipes typically comes to £650 to £1,700, averaging around £1,000. A single repaired joint costs far less, and scaffold, if the run is high, can change the total. Ask whether any quote includes VAT.

Whichever method you choose, agree it before work starts and agree it with the figure in front of you. Splitting a price that has already been written down is far easier than arguing over an invoice afterwards. If one neighbour wants a better product than the other, such as aluminium rather than plastic, the person who wants the upgrade can reasonably pay the difference.

The cleanest way to handle a shared gutter is to have one roofer look at the entire length, so the work is done in a single visit and the joint between the two houses is not left half repaired. Jobs done separately, a year apart, often mean two lots of access and a mismatch where the old and new meet.

We start every job with a survey and send photos of your own gutter, so you can show your neighbour exactly what is wrong. You receive a single total in writing for whatever work the two of you agree. If the two households want to pay separately, tell us at the start and we can write down how the work is to be divided.

The fault is often smaller than people fear. A dripping joint may only need re-sealing, which our answer on a leaking gutter joint explains, while a run that has dropped away from the fascia is covered in how to fix a sagging gutter. If every length is worn out, see what gutter replacement costs, or our gutters, soffits and fascias page. Our next step with you: email the address, a ground-level photo of the run, and which house the downpipe sits beside.
