Gutter sealing in Pitshanger
It’s easy to live with a dripping gutter joint, but each shower sends water to the same place. Resealing it is a small job if the gutter is otherwise in good order. If you’re dealing with water running down the wall below the gutter and gaps along fascia and soffit joints, we can put it right, on soffit joints, gutter end caps and garage door frames alike.
Working on the outside of a London home means planning access: shared paths, upper floors and parking. For a home in Pitshanger, tell us how high the joints are and how to reach the back of the building.
You are covered for a year from the day we finish. If anything is not right with it, phone 0345 464 0079 or drop us an email.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Check fascia and soffit joints for gaps
- Keep ladders off the guttering
- Watch for drips in a downpour
- Get a dropping gutter looked at quickly
Keep downpipes clear, so water can get away. Blockages push water back along the gutter.
Early sealing limits how much water hits the wall. We will let you know if the gutter needs more than sealant.
Pitshanger buildings and the weather
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Pitzhanger Manor (about 1.1 miles south) nearby, there’s older building stock in the area around Pitshanger as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
In the older streets around Church of St Barnabas, the joints between older walls, newer extensions and the roofline need a sealant that can move. Rented homes near Castle Bar Park station change hands often, and leaking gutter joints on a rental are best caught before they stain the walls.

- Water dripping where gutter sections meet
- Dripping gutter ends
- Internal damp traced to a gutter joint
- Cracked sealant along roofline trims
For site and facilities teams at buildings such as North Ealing Primary School, its movement joints, gutters and trims need looking after like any other building’s.

DIY sealant or a professional job?
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.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
