Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
About our gutter sealing in Primrose Hill
A leaking gutter joint marks the wall and wets the ground underneath. Resealing the joint is often all it needs, as long as the gutter is sound. We work on roofline trims, garage door frames and gutter end caps, and people most often call us about streaks down the brickwork from a leaking joint and damp patches inside below a leaking gutter.
Newer London blocks are built with movement joints in brick and render, and with cladding joints sealed with mastic. Older terraces have their own weak points: gutter joints, roofline trims and the joint where an extension meets the original wall.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

Primrose Hill buildings and the weather
In terraces and conversions, gutters and walls are often shared with the neighbours, so it’s worth agreeing who is responsible before work starts. Historic houses like Winfield House (about 0.7 miles south) are a reminder that the area around Primrose Hill has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
If you look after a building such as St Paul's Church of England Primary School, its movement joints, gutters and trims need looking after like any other building’s. For landlords with property near Kentish Town West station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

Related advice
What the job involves on each surface
Gutter end caps
End caps are resealed where they meet the gutter, after cleaning and drying.
Gutter joints
When a joint drips, the gutter is often still sound. Resealing is generally enough.
Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Sort out a dripping joint early
- Check that water runs out of the downpipes
- Keep an eye out for wet patches below a joint
- Look at the gutters while it’s raining
If a gutter starts to sag, get the brackets looked at. If it drops, the joints will open.
The sooner a gutter leak is sealed, the less water reaches the wall. We will let you know if the gutter needs more than sealant.
Common problems we fix in Primrose Hill
Gutter joints depend on seals that wear out. Sun and cold make the gutter expand and contract, and old seals crack or slip.
Keep an eye out for these signs:
- Dripping gutter ends
- Gaps along fascia and soffit joints
- Damp patches inside below a leaking gutter
- Water dripping where gutter sections meet
Primrose Hill is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
