DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Gutter sealing in Cadmore End
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’ll tell you. We work on uPVC fascias, gutter joints and soffit joints, and the jobs we see most are stop ends leaking at the end of a run and leaking gutter joints and stop ends.
Outside joints can only be sealed when they’re dry, so work in Cadmore End is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
All of our work is guaranteed for twelve months.

What gutter sealing looks like in Cadmore End
London and the South East are among the drier parts 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 West Wycombe Park House (about 2.8 miles east) nearby, there’s older building stock in the area around Cadmore End as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Rented homes near Saunderton station change hands often, and a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. Schools such as Cadmore End CofE School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

Do you need gutter sealing in Cadmore End?
Overflowing gutters can look like leaking joints. If the downpipe is blocked, water has nowhere to go, which is why we look before we seal.
The most common problems we see are:
- Rain getting in around a garage door
- Water running down the wall below the gutter
- Old gutter sealant that has let go
- Gaps along fascia and soffit joints
For an older house near a landmark such as Church of St Mary Le Moor, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Questions to ask before you book
- What the cure time is
- What preparation is included
- What guarantee comes with the work
- What happens if they find a problem under the old sealant
How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours, depending on the number of joints and the access. Somewhere like Cadmore End needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at the gutters, fascias and trims and agree the joints to seal.
- Each joint is cleaned and any old sealant removed.
- The joints are dried.
- We apply exterior or gutter sealant and finish it neatly.
- The joints are checked once sealed.
How to prepare
- Clear items away from the joints we’re working on
- Keep pets and children clear of the area while we work
- Mention any leaks or damp you’ve noticed

Why deal with it now?
Water from a leaking joint hits the same spot every time. Over time that can stain brickwork, mark render and encourage damp so early sealing is worthwhile. Older cottages and farmhouses around Cadmore End can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

- Every job guaranteed for a year

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Sort out a dripping joint early
- Watch the wall under the gutters for staining
- Check the gutters during heavy rain
- Make sure downpipes aren’t blocked
Clear the gutters once or twice a year so water doesn’t sit on the joints. Standing water strains every seal.
If an end cap is dripping, deal with it before winter. Water down the wall all winter can cause damp inside.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Cracked, split or warped gutter sections
- Rotten or damaged fascia boards
- Problems with the roof covering
If in doubt, phone 0345 464 0079 or email us and we will say what we think.
