About our gutter sealing in Deane
A leaking gutter joint marks the wall and wets the ground underneath. Resealing the joint is often all it needs, as long as the gutter is sound. We are often asked to deal with water running down the wall below the gutter and fascia boards with gaps between them, on soffit joints, gutter joints and gutter end caps.
External sealant needs dry, clean surfaces, so work around Deane is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
All our work comes with our 12-month guarantee, wherever you are in Hampshire.

The process
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the job takes anything from an hour or two to a few hours in most cases. In a small place like Deane, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we agree which joints need sealing.
- Each joint is cleaned and any old sealant removed.
- The joints are dried.
- The sealant is applied and finished.
- The joints are checked once sealed.
How to prepare
- Let us know about stairs, lifts or work at height
- Let us know about parking restrictions
- Let us know about earlier repairs to the joints

What affects the quote in Deane

- The amount of work
- Whether the work is at height
- Any mould that needs treating
- The type of sealant required
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What we need to know

Leave it or put it right?
A bead squeezed onto a wet joint might hold for a while, but it soon lets go. Cleaning out and drying the joint first is what makes it last. Where a wall is exposed, as many are in small places like Deane, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Doing several joints on one visit normally makes better use of the time than several visits. You will get one clear quote for the whole job.

Questions from Deane
Do you cover Deane for gutter sealing?
Yes. Our work covers London and the South East, and Deane is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we will give you a clear price.
Will you come out to Deane?
Yes. Deane is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
What do you need from me for a quote?
A short description and the location, with pictures by email if possible. We’ll ask anything else we need to know.
Will the old sealant be removed?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
How long should I leave it?
That depends on the sealant used, so follow the cure time we give you.
Do you clean gutters?
We clean the joints we’re sealing and clear debris we find nearby. Cleaning the whole run is a different job.
How the job changes by surface
uPVC fascias
Gaps in fascias spoil the roofline. A neat bead closes them up.
Soffit joints
We choose a sealant colour that suits the soffit, where one is available.
Deane buildings and the weather
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near Church of All Saints, an extension built onto an older house moves differently, and the joint between them takes the strain.

What else we do in Deane
When to call us in Deane
End caps get knocked or pushed by water. Once the seal behind them fails, they drip.
Most people get in touch when they notice something like this:
- Water running down the wall below the gutter
- Failed sealant on a garage door frame
- End caps that drip every time it rains
- Quick sealant fixes on gutters that didn’t last
If you let a flat or house near Overton station, leaking gutter joints on a rental are best caught before they stain the walls.
Questions to ask before you book
- How long to leave it before use
- How the joint is cleaned and prepared
- What insurance they hold
- What product goes in the joint
How to look after the new joints
Aftercare is simple:
- Get leaks sealed before the wet months
- Make sure downpipes are not blocked
- Watch the wall under the gutters for staining
- Don’t lean ladders against the gutter itself
Give the sealant the cure time we tell you and avoid disturbing it.
Leaking gutter joints get worse over time. Water keeps hitting the same part of the wall and that can cause damp inside.
