What gutter sealing looks like in Dunk's Green
Historic houses like Old Soar Manor (about 0.9 miles north-east) are a reminder that the area around Dunk's Green has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Plaxtol Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you let a flat or house near Borough Green & Wrotham station, leaking gutter joints on a rental are best caught before they stain the walls.

Common problems we fix in Dunk's Green
Sagging sections pull joints apart. Sealing won’t hold if the gutter keeps dropping so the brackets need attention first.
The most common problems we see are:
- Trim joints where the sealant has failed
- Leaking gutter joints and stop ends
- Water running down the wall below the gutter
- Internal damp traced to a gutter joint
In the older streets around Plaxtol Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

What else we do in Dunk's Green
Dunk's Green: your questions answered
Is Dunk's Green in your area for gutter sealing?
Yes. We work across London and the South East, and Dunk's Green is part of that. You can call 0345 464 0079 or email us and tell us what needs doing.
Is Dunk's Green within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Do you clean gutters?
We clear debris near the joints because the joint must be clean. A full gutter clean is a separate job.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do the sealants smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us, and we’re fully insured.
Why act early in Dunk's Green
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. Where a wall is exposed, as many are in small places like Dunk's Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.
Why us?
- A 12-month guarantee on all work
- Anti-fungal silicone where joints get wet

What the job involves on each surface
Gutter end caps
End caps are resealed where they meet the gutter once clean and dry.
Gutter joints
Most gutter leaks start at a joint between sections. They’re cleaned out, dried and resealed.
Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep the gutters clear of debris
- Watch for drips in a downpour
- Keep downpipes clear
- Get a dropping gutter looked at quickly
Look at fascia and trim joints when you’re checking the gutters. Splits are easier to seal early.
Leaking gutter joints get worse over time. The same spot gets soaked every time it rains, which can lead to staining and damp.
What affects the cost of gutter sealing
You will get a clear quote before work begins. It’s based on:
- The number of rooms or windows
- The product the joint needs
- The old material and how stubborn it is
- How easy the joints are to reach
A few things move the cost up or down: 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.
What we need to know
To make quoting easier, let us know:
- Where the property is
- What the problem is, such as mould, gaps, leaks or cracking
- Pictures of the joints, sent by email
- Roughly how big the job is
For a quote, phone 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. You’ll have a clear quote before any work starts.
The process
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes an hour or two for a few joints, longer for a full run. Somewhere as small as Dunk's Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at the gutters, fascias and trims and agree the joints to seal.
- Each joint is cleaned and any old sealant removed.
- We make sure everything is dry.
- The sealant is applied and finished.
- The joints are checked once sealed.
How to prepare
- Keep children and pets away from the work area
- Let us know if you’ve seen damp or leaks
- For indoor joints, keep the area dry beforehand if you can

Related advice
Should I try it myself first?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
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.
