Gutter sealing for homes and businesses in St Luke's
Many dripping gutters are just a failed joint or end cap. We clean out the joint, dry it and reseal it with a sealant made for guttering. If the gutter itself has failed, we say so. If you are dealing with damp patches inside below a leaking gutter and leaking gutter joints and stop ends, we can put it right.
Newer London blocks are built with movement joints in brick and render, and with cladding joints sealed with mastic. Period houses have different weak points, such as gutter joints, trims and the line where an extension meets the old wall, and both kinds of building are found across London.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Leave it or put it right?
New gutters cost far more than a few resealed joints. Where the gutter is in good order and only a joint leaks, resealing is the sensible fix. If it has failed, we will tell you. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in St Luke's, the repair is bigger than a sealant job.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first.

Walls and rooflines in St Luke's
Historic houses like Mansion House (about 0.8 miles south) are a reminder that the area around St Luke's 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. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to Jewin Welsh Presbyterian Chapel include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. If you look after a building such as St Luke's CofE Primary School, larger buildings have long runs of movement joint that eventually need resealing.

Common problems we fix in St Luke's
A sealant applied to a damp or dirty joint will not bond. Rushed repairs often do not last long for this reason.
If you can see any of these, it’s time to have the joints looked at:
- Rain getting in around a garage door
- Damp patches inside below a leaking gutter
- Wet patches on the wall under a gutter joint
- Stop ends leaking at the end of a run
St Luke's is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
What your quote should include
- How the colour is chosen
- When the joint can take water or movement
- What preparation is included
- How long the guarantee is
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Get a dropping gutter looked at quickly
- Rest ladders on the wall, not the gutter
- Clear leaves and moss from the gutters
- Keep an eye out for wet patches below a joint
Keep downpipes clear so the gutter can drain. Blockages push water back along the gutter.
Once roofline sealant splits, water can get behind it. Resealing early protects the boards and the wall below.
What we cannot put right
In fairness, some problems need a different trade:
- Cracked, split or warped gutter sections
- Gutters that have dropped or pulled away
- Fascias that need replacing
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think before you book.
Where we work in St Luke's

How it works
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work begins. The work normally takes an hour or two for a few joints, longer for a full run. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in St Luke's. It helps if you can point us to a visitor permit or a bay close to the door.
- First we agree which joints need sealing.
- Each joint is cleaned and any old sealant removed.
- The joints are dried.
- The sealant is applied and finished.
- The joints are checked once sealed.
Before we arrive
- Mention any sign-in or site rules at work premises
- Keep pets and children clear of the area while we work
- Try not to wet indoor joints just before the visit

FAQs for St Luke's
Can parking be tricky for a visit in St Luke's?
Parking in St Luke's, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Can you help a landlord with a rental near Old Street station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Where are you based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Is gutter cleaning part of the job?
The joints we seal are cleaned out and any debris nearby is cleared. A full gutter clean is a separate service.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Is it possible to stop a gutter joint dripping with sealant?
Most of the time. A sagging or cracked gutter needs more than sealant, and we will tell you.
Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first.
How the job changes by surface
Gutter joints
Gutter joints move and sit in water. A dedicated gutter sealant suits them.
Gutter end caps
A leaking end cap sends water straight down the wall. It’s a quick reseal.
