Gutter sealing in Swiss Cottage, done properly
Sealant only bonds to a clean, dry joint. So the old sealant and grime come out first and the joint is dried before the new sealant goes in. We work on uPVC fascias, gutter end caps and garage door frames, and common reasons people get in touch are water dripping where gutter sections meet and old gutter sealant that has let go.
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 there’s a problem with our work within the year, let us know and we’ll sort it.

Swiss Cottage buildings and the weather
London terraces and converted houses often share gutters, downpipes and walls, so it’s worth agreeing who is responsible before work starts. With historic houses such as Winfield House (about 0.9 miles south-east) nearby, there’s older building stock in the area around Swiss Cottage as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Homes close to Church of All Souls include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant. If you let a flat or house near South Hampstead station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. Swiss Cottage is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Leave it or put it right?
A dripping stop end can soak the wall right through the wet months. Resealing it is a quick job compared with treating damp later. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Swiss Cottage, the repair is bigger than a sealant job.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
What you get with us
- Full insurance on every job

How the job changes by surface
Gutter joints
A gutter joint has to cope with movement and standing water. A dedicated gutter sealant suits them.
uPVC fascias
Joints between fascia boards can open over time. They’re sealed tidily in a suitable colour.
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Sort out a dripping joint early
- Have sagging gutters refixed early
- Look at the gutters while it’s raining
- Make sure downpipes aren’t blocked
Make sure downpipes are not blocked so the gutter can drain. Blockages push water back along the gutter.
If an end cap is dripping, deal with it before winter. Water down the wall all winter can cause damp.
Honest limits
In fairness, some problems need a different trade:
- Fascias that need replacing
- Brackets that have snapped or loosened
- Roof leaks, slipped tiles or failed flashing (a roofer’s job)
