What gutter sealing looks like in South Street
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. In terraces and conversions, gutters and walls are often shared with the neighbours, so it’s worth agreeing who is responsible before work starts.
Managing a site like Charles Darwin School? Then larger buildings have long runs of movement joint that eventually need resealing. In the older streets around Church of St Mary the Virgin, older walls, gutters and the joints where extensions meet them need a flexible sealant. Rented homes near Oxted station change hands often, and leaking gutter joints on a rental are best caught before they stain the walls.

About our gutter sealing in South Street
It’s easy to live with a dripping gutter joint, but the water lands on the same spot every time it rains. Resealing it is a small job while the gutter is still sound. We work on gutter end caps, garage door frames and uPVC fascias, and common reasons people get in touch are rain getting in around a garage door and internal damp traced to a gutter joint.
Working on the outside of a London home means planning access: shared paths, upper floors and parking. For a home in South Street, tell us how high the joints are and how to reach the back of the building.
There’s a 12-month guarantee on every job, large or small.

What else we do in South Street
How the job changes by surface
Gutter end caps
We seal end caps from the inside where we can reach, after cleaning and drying.
Garage door frames
Frame-to-brick joints face the weather. An exterior sealant suits them.
Aftercare tips
Good habits help new joints last longer. A few tips:
- Keep ladders off the guttering
- Glance at the soffit joints now and then
- Get a dropping gutter looked at quickly
- Keep an eye out for wet patches below a joint
A sagging gutter needs its brackets checked. Movement will pull the joints open again.
Early sealing limits how much water hits the wall. We’ll let you know if the gutter needs more than sealant.

Advice
South Street: your questions answered
Can you do gutter sealing in South Street?
Yes, South Street is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.
Can parking be tricky for a visit in South Street?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used before we leave.
Can sealant stop a sagging gutter leaking?
Sealant won’t hold a sagging gutter. The gutter needs refixing by a gutter installer.
Can you fit new guttering?
No. Our work is sealing joints and replacement is a job for an installer.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Where do you work from?
Our base is in Crawley, and we work across South East England, London and Scotland.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected.
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Work for landlords, hotels and businesses
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will give you a quote.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Leave it or put it right?
If the problem is a blocked downpipe, sealing will not help. We look at what’s really happening and point you to the right trade if needed. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in South Street.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.
