Gutter sealing in Angel
Many dripping gutters are just a failed joint or end cap. The joint is cleaned, dried and resealed using a gutter sealant. If the gutter itself has failed, we say so. If you are dealing with cracked sealant along roofline trims and stop ends leaking at the end of a run, we can put it right, whatever the surface.
London’s terraces and conversions often share walls, gutters and downpipes with their neighbours, so one failed joint can cause damp for more than one household. For a flat in Angel, check the lease for who looks after the outside.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Why deal with it now?
Sealant will not clear a blocked downpipe. We check the cause first and tell you if something else is needed. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Angel, the repair is bigger than a sealant job.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
When to call us in Angel
A sealant applied to a damp or dirty joint will not bond. Some quick repairs peel off within a season or two.
If you can see any of these, it’s time to have the joints looked at:
- Dripping gutter ends
- Garage door frames letting rain in
- Old sealant on roofline trims that has split
- Leaking gutter joints and stop ends
If you live in an older home near St Mark's Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Look for streaks or damp on the wall below gutters
- Glance at the soffit joints now and then
- Check that water runs out of the downpipes
- Get a dropping gutter looked at quickly
Leave the new sealant to cure as we advise and avoid disturbing it.
Rain getting in round a garage door frame can damage what’s stored inside. A reseal sorts it while the frame is sound.
When something else is needed
To be straight with you, some problems need a different trade:
- Boards that have decayed or split
- Guttering that needs replacing
- Water backing up from a blocked pipe
If you’re not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer before booking.

Outside joints around Angel
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Dr Johnson's House (about 1.2 miles south) are a reminder that the area around Angel has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
Angel is in London, so parking needs planning: let us know about parking bays, permits or a driveway. Managing a site like St John Evangelist RC Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.

A fresh seal around the frame stops rain getting in.
What we do, step by step
We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. The job normally takes a few hours, depending on the number of joints and the access. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Angel. It helps if you can point us to a visitor permit or a bay close to the door.
- We start by tracing the leak and checking the gutter itself is sound.
- We clean out the joint and take out the old sealant.
- The area is dried so the sealant can bond.
- We seal the joint with a sealant made for gutters and outdoor use.
- We check the run and clear any debris we find while we are there.
Preparing for the visit
- Mention if the joints have been sealed before
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us if parking is tricky

Questions from Angel
Can parking be tricky for a visit in Angel?
Parking in Angel, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Is Angel in your area for gutter sealing?
Yes, Angel is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing.
Is sealant enough for a gutter that has dropped?
No. A sagging gutter pulls its joints apart so it needs refixing before sealing.

Can tenants book the work?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
Can you fit new guttering?
