DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Gutter sealing in East Dean, done properly
Many dripping gutters are just a failed joint or end cap. We clean out the joint, dry it and reseal it with a sealant made for guttering. If the gutter itself has failed, we say so. If you’re dealing with damp patches inside below a leaking gutter and water running down the wall below the gutter, we can put it right.
External sealant needs dry, clean surfaces, so work around East Dean is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
All our work is covered by a 12-month guarantee.

Surface by surface
Garage door frames
Garage door frames let rain in when their sealant fails. It’s removed and renewed.
Gutter end caps
We seal end caps from the inside where we can reach once clean and dry.
Why act early in East Dean
If the problem is a blocked downpipe, sealing will not help. We look at what’s really happening and point you to the right trade if needed. Where a wall is exposed, as many are in small places like East Dean, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

How it works
On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before work begins. Most jobs take an hour or two for a few joints, longer for a full run. Somewhere as small as East Dean, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we trace the drip and check the gutter isn’t damaged.
- We remove the old sealant and clean the joint.
- The joint is dried before sealing.
- A gutter sealant is applied to the joint.
- The gutter is checked and debris around the joints cleared.
Before we arrive
- Move anything stored near the joints
- Tell us about access, such as stairs, a lift or high-level joints
- Keep children and pets away from the work area

East Dean questions
Do you cover smaller places like East Dean?
Yes, East Dean is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Does the coastal weather in East Dean affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Are you insured?
Yes. We are fully insured.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can you seal over the old sealant?
No, it won’t last. 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.
Is it possible to stop a gutter joint dripping with sealant?
Most of the time. If the gutter is sagging or cracked, sealing won’t last, and we will tell you.
Can landlords and businesses book you?
Yes, regularly. We can quote for several properties at once, and between tenancies is a good time for the work.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little.

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Glance at the soffit joints now and then
- Make sure downpipes aren’t blocked
- Watch the wall under the gutters for staining
- Get a dropping gutter looked at quickly
Keep the gutters clear of leaves and moss, so water drains away past the joints. Standing water strains every seal.
Early sealing limits how much water hits the wall. If we find a bigger problem, we will tell you.
East Dean buildings and the weather
East Dean is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on gutter, fascia and roofline joints, which can dry out and crack sooner where a building faces the weather. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to The Parish Church of St Simon and St Jude include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.
