How we handle gutter sealing in Merton
Water dripping from a gutter joint can stain walls and soak the ground below. Often a reseal is enough if the gutter is not damaged. We work on garage door frames, uPVC fascias and soffit joints, and common reasons people get in touch are fascia boards with gaps between them and rain getting in around a garage door.
Around Merton, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

How the visit works
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours, depending on the number of joints and the access, including the tidy-up. For a village or hamlet like Merton, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We find where the water is coming from and check the gutter is sound.
- We remove the old sealant and clean the joint.
- We dry the joint so the new sealant can bond.
- A gutter sealant is applied to the joint.
- The gutter is checked and debris around the joints cleared.
How to prepare
- Mention any parking rules near the property
- Let us know about stairs, lifts or work at height
- Keep children and pets away from the work area

If in doubt, phone 0345 464 0079 or email us and we will say what we think.

Surface by surface
Gutter joints
When a joint drips, the gutter is often still sound. Sealing the joint often stops it.
Soffit joints
We choose a sealant colour that suits the soffit, where one is available.
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Watch for drips in a downpour
- Keep an eye out for wet patches below a joint
- Clear leaves and moss from the gutters
- Get a dropping gutter looked at quickly
Look at fascia and trim joints when you are checking the gutters. A small split is quicker to put right.
Rain getting in round a garage door frame can damage what’s stored inside. Resealing the frame is a quick job.
Gutter sealing in Merton: local notes
Historic houses like Boarstall Tower (about 3.7 miles south-east) are a reminder that the area around Merton has older buildings as well as new. Where a home is older, 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as Church of St Swithin, an extension built onto an older house moves differently, and the joint between them takes the strain.

Why it’s worth doing now in Merton
A dripping stop end can soak the wall right through the wet months. It’s a small job to put right compared with treating damp later. Older cottages and farmhouses around Merton 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 the work is at height. We take all of that into account in your quote.

- Anti-fungal silicone where joints get wet

Questions from Merton
Is Merton in your area for gutter sealing?
Yes, Merton is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or email us and tell us what needs doing.
Do you cover smaller places like Merton?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
What about gutters on a second or third storey?
Single-storey and low-level gutters are straightforward. For higher work, tell us about access and we will confirm what’s needed.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done.
Do you guarantee gutter sealing?
All our work carries a one-year guarantee.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures.
Is it possible to stop a gutter joint dripping with sealant?
In most cases, yes. If the gutter is sagging or cracked, sealing will not last, and we will tell you.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Should I try it myself first?
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, then guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Do you need gutter sealing in Merton?
Gutter joints depend on seals that wear out. Sun and cold make the gutter expand and contract, and old seals crack or slip.
Common reasons people contact us are:
- Dripping gutter ends
- Old sealant on roofline trims that has split
- Quick sealant fixes on gutters that didn’t last
- Wet patches on the wall under a gutter joint
For landlords with property near Bicester Village station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.
