Gutter sealing in Dockenfield, done properly
We seal leaking gutter joints, end caps, fascia and soffit joints, along with roofline trims and garage door frames. It’s all about the joints rather than new guttering. We work on garage door frames, uPVC fascias and gutter end caps, and people most often call us about streaks down the brickwork from a leaking joint and internal damp traced to a gutter joint.
Somewhere as small as Dockenfield, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
You get a one-year guarantee, the same in Dockenfield as everywhere else we work.

What gutter sealing looks like in Dockenfield
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Farnham Castle (about 4.1 miles north) are a reminder that the area around Dockenfield has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Homes close to The Church Of The Good Shepherd include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

What affects the cost of gutter sealing
Call for a quick quote. What matters most is:
- The size of the job
- When we can work, for business premises
- Which sealant suits the joint
- Whether the work is at height
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.
Asking for a quote
There’s no need for technical detail. It helps if you can tell us:
- How many joints, rooms or windows are involved
- The problem you’ve noticed
- The address or postcode of the job
- Any access issues, like height or stairs
For a quick quote, get us on the phone, or email us if that’s easier. Tell us about the joints that need doing and we’ll explain what’s involved and send you a clear quote.
What happens on the day
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take an hour or two for a few joints, longer for a full run. Somewhere as small as Dockenfield, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We find where the water is coming from and check the gutter is sound.
- The old sealant and dirt are cleaned out of the joint.
- We dry the joint so the new sealant can bond.
- We seal the joint with a sealant made for gutters.
- The gutter is checked and debris around the joints cleared.
Before we arrive
- Let us know about earlier repairs to the joints
- For indoor joints, keep the area dry beforehand if you can
- On commercial sites, let us know about site rules

How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Keep downpipes clear
- Look along the fascias for open joints
- Watch for drips in a downpour
- Clear leaves and moss from the gutters
A sagging gutter needs its brackets checked. If it drops, the joints will open.
Leaking gutter joints get worse over time. Water keeps hitting the same part of the wall and that can cause damp inside.

What happens if it’s left?
Replacing guttering is a much bigger job than sealing joints. If the gutter is sound and the drip is a joint a reseal is all it needs. If it has failed, we will tell you. Where a wall is exposed, as many are in small places like Dockenfield, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Instead of a standard rate, 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.
