About our gutter sealing in Morden
Across Morden, we reseal gutter joints, end caps and roofline trims. Low-level work is straightforward and if it’s higher up, let us know and we’ll confirm what access is needed. We work on roofline trims, soffit joints and uPVC fascias, and people most often call us about stop ends leaking at the end of a run and damp patches inside below a leaking gutter.
Modern London flats rely on sealed movement joints and cladding joints. Older terraces have their own weak points: gutter joints, roofline trims and the joint where an extension meets the original wall, and both kinds of building are found across London.
A one-year guarantee comes as standard, so you’re covered after we have gone.

Common questions in Morden
Do you cover Morden for gutter sealing?
Yes, Morden is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.
I let a flat near St Helier station. Can you help?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
Do you take out the old sealant first?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
Do you guarantee gutter sealing?
Every job comes with our 12-month guarantee.
Will you clear out my gutters?
We clear debris near the joints, so the sealant can bond. A full gutter clean is a separate job.
What does gutter sealing cost?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before work begins.
Can you seal over the old sealant?
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 work on high-level gutters?
Single-storey work is the most straightforward. For anything higher, we will confirm what access is needed once we know more.
How to look after the new joints
To keep the joints looking good and working properly:
- Get leaks sealed before the wet months
- Check fascia and soffit joints for gaps
- Have sagging gutters refixed early
- Keep an eye out for wet patches below a joint
If a gutter starts to sag, get the brackets looked at. If it drops, the joints will open.
Rain getting in round a garage door frame can damage what’s stored inside. A reseal sorts it while the frame is sound.

How the job changes by surface
Gutter joints
A dripping joint does not always mean a failed gutter. Sealing the joint often stops it.
Roofline trims
We seal the trims, not the roof. Roofing problems need a roofer.
How the visit works
At the end, we look at the finished work together and tell you how long to leave it. The visit itself normally takes anything from an hour or two to a few hours, depending on the size of the job. In Morden, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- 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.
Before we arrive
- Try not to wet indoor joints just before the visit
- Mention any leaks or damp you’ve noticed
- Mention any sign-in or site rules at work premises

Advice
Landlord and commercial work in Morden
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
For anyone letting property in or around Morden, several properties can be quoted together. Just tell us the addresses and what each one needs.
Common problems we fix in Morden
Sagging sections pull joints apart. Sealing won’t hold if the gutter keeps dropping, so the gutter needs refixing first.
Signs it’s time to call us include:
- Water running down the wall below the gutter
- Stop ends leaking at the end of a run
- Fascia boards with gaps between them
- Garage door frames letting rain in
Morden is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Walls and rooflines in Morden
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. London terraces and converted houses often share gutters, downpipes and walls, so it’s worth agreeing who is responsible before work starts.
Rented homes near St Helier station change hands often, and a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. If you live in an older home near St Lawrence Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.
