St James's Gutter Sealing
Problem with your gutter and fascia joints in St James's? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.
- Earlier gutter repairs that have peeled off
- Damp patches inside below a leaking gutter
- Gaps along fascia and soffit joints
Gutter sealing in St James's, done properly
We do not replace gutters, fascias or roofs. What sealant does is close joints and it cannot mend broken brackets, split sections or blocked downpipes. Common call-outs are for old gutter sealant that has let go and wet patches on the wall under a gutter joint, on gutter joints, roofline trims and garage door frames.
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.
Whatever the size of the job, it’s backed by our one-year guarantee in St James's and across Greater London.

How the job changes by surface
Soffit joints
We choose a sealant colour that suits the soffit.
Gutter end caps
A leaking end cap sends water straight down the wall. It’s a quick reseal.
Outside joints around St James's
London terraces and converted houses often share gutters, downpipes and walls, so it’s worth agreeing who is responsible before work starts. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as Soho Parish CofE Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. St James's is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Work for landlords, hotels and businesses
We work for landlords and agents as well as householders. Sealant work between tenants is a simple way to keep a property in good order.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Aftercare tips
Aftercare is simple:
- Keep an eye out for wet patches below a joint
- Do not leave a sagging gutter
- Rest ladders on the wall, not the gutter
- Keep the gutters clear of debris
Make sure downpipes aren’t blocked, so water can get away. A blocked pipe backs water up to the joints.
A leaking stop end is best sealed before the wet months. Water down the wall all winter can cause damp.
Common problems we fix in St James's
Gutter joints rely on seals that age. Sun and cold make the gutter expand and contract, and old seals crack or slip.
Look out for any of the following:
- Open joints in fascias and soffits
- Failed sealant on a garage door frame
- Dripping gutter ends
- Trim joints where the sealant has failed

Questions from St James's
Do you work for landlords with property near London Charing Cross station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
Is parking an issue for gutter sealing in St James's?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Is sealant enough for a gutter that has dropped?
Sealing a sagging joint will not last. A gutter installer needs to refix it, and we will tell you if that is what we find.
How long should I leave it?
It depends on the product and the temperature. Before we leave, we will tell you the cure time.
What should I tell you?
A short description and the location. We will ask anything else we need to know.
Do you offer different sealant colours?
Most of the time, yes. We’ll explain which colours are available.
Are you fully insured?
Yes. We’re fully insured for domestic and commercial work.
What does gutter sealing cost?
Every job is different, so each one gets its own quote. For a quick quote, ring 0345 464 0079 or drop us an email and let us know what needs doing and where.
Leave it or put it right?
A dripping gutter joint keeps wetting the same patch of wall. Over time that can stain brickwork, mark render and encourage damp so early sealing is worthwhile. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in St James's.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will explain what it covers.
