Gutter sealing in Croydon
Our work covers gutter joints and end caps as well as fascias and soffits, along with roofline trims and garage door frames. It’s all about the joints, not replacing the gutter. We work on soffit joints, uPVC fascias and roofline trims, and common reasons people get in touch are fascia boards with gaps between them and water dripping where gutter sections meet.
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.
Each job carries a 12-month guarantee, large or small.

What affects the cost of gutter sealing
Some jobs are bigger than they look, and some smaller. The main factors:
- How much old sealant there is and how hard it is to remove
- When we can work, for business premises
- Mould in or behind the old joints
- The number of rooms or windows
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- Where the job is, and your postcode
- What the problem is, such as mould, gaps, leaks or cracking
- Photos by email, if that’s easy
- If someone has resealed it before

Different surfaces, different methods
uPVC fascias
We seal fascia joints, not replace the boards. Damaged boards need replacing by an installer.
Roofline trims
Trim joints are cut out and resealed.
Why it’s worth doing now in Croydon
Replacing fascias because of open joints is normally unnecessary. A neat seal closes the gaps as long as the boards are in good condition. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
Why us?
- White, clear, grey or coloured to suit, where the product allows
- Old sealant always removed completely
- Colour picked to suit the job
- More than 20 years in sealant work

What we can’t put right
We’d rather tell you now than do work that won’t last, so these are the limits:
- Gutters that have dropped or pulled away
- Downpipes that are blocked or broken
- Guttering that needs replacing
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly.

What gutter sealing looks like in Croydon
With historic houses such as Addington Palace (about 2.5 miles east) nearby, there’s older building stock in the area around Croydon 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. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Croydon is in London, so parking needs planning: let us know about parking bays, permits or a driveway. For an older house near a landmark such as St Andrew's, the joints between older walls, newer extensions and the roofline need a sealant that can move. Schools such as Heathfield Academy are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
