Gutter sealing in St Helier
A lot of gutter leaks come down to one tired joint. We clean out the joint, dry it and reseal it with a sealant made for guttering. If the gutter is broken or sagging, we will tell you. Typical jobs include cracked sealant along roofline trims and rain getting in around a garage door, across roofline trims, gutter joints and soffit joints.
Modern London flats rely on sealed movement joints and cladding joints. Period houses have different weak points, such as gutter joints, trims and the line where an extension meets the old wall.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Why it’s worth doing now in St Helier
Replacing fascias because of open joints is usually unnecessary. Sealing the joints tidies them up if the boards are sound. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Ask us for a quote and we’ll explain what it covers.

Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
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.
