Gutter sealing for homes and businesses in Leatherhead
A lot of gutter leaks come down to one tired joint. The joint is cleaned, dried and resealed using a gutter sealant. If the gutter itself has failed, we say so. We are often asked to deal with trim joints where the sealant has failed and damp on an inside wall under a dripping gutter, across gutter end caps, garage door frames and gutter joints.
Extensions are a common sight on houses around Leatherhead, and the joint where new wall meets old is a classic place for water to get in. Sealing it properly means the right joint depth and a flexible sealant, not a quick bead.
Big or small, you get the same 12-month guarantee.

Surface by surface
Roofline trims
Sealing roofline trims is joint work only. Roofing problems need a roofer.
Gutter joints
A gutter joint has to cope with movement and standing water. A dedicated gutter sealant suits them.
Can I do it myself?
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.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Keep an eye out for wet patches below a joint
- Rest ladders on the wall, not the gutter
- Make sure downpipes aren’t blocked
- Have sagging gutters refixed early
Clear the gutters once or twice a year so water doesn’t sit on the joints. Water left in a gutter tests every joint.
Early sealing limits how much water hits the wall. If we find a bigger problem, we’ll tell you.
When something else is needed
We will always be straight with you, so here’s what sealant cannot fix:
- Roof leaks, slipped tiles or failed flashing (a roofer’s job)
- Rotten or damaged fascia boards
- A gutter length that has split
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly.

Common problems we fix in Leatherhead
Stop ends take pressure from water running along the gutter. Once the seal behind them fails, they drip and runs down the wall.
Common reasons people contact us are:
- Water dripping where gutter sections meet
- Failed sealant on a garage door frame
- Old gutter sealant that has let go
- Cracked sealant along roofline trims
Rented homes near Leatherhead station change hands often, and a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.

What gutter sealing looks like in Leatherhead
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Polesden Lacey (about 3.4 miles south-west) are a reminder that the area around Leatherhead 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.
For site and facilities teams at buildings such as Leatherhead Trinity School and Children's Centre, its movement joints, gutters and trims need looking after like any other building’s. Homes close to Church of Our Lady and St Peter include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.
