Bankside Gutter Sealing
Problem with your gutter and fascia joints in Bankside? We remove the old material, prepare the joints and seal them properly, with a 12-month guarantee.
- Water dripping where gutter sections meet
- Trim joints where the sealant has failed
- Quick sealant fixes on gutters that didn’t last
How we handle gutter sealing in Bankside
Water dripping from a gutter joint can stain walls and soak the ground below. Resealing the joint is often all it needs if the gutter is not damaged. If you’re dealing with trim joints where the sealant has failed and internal damp traced to a gutter joint, we can put it right, on roofline trims, garage door frames and soffit joints alike.
London’s terraces and conversions often share walls, gutters and downpipes with their neighbours, so a leaking gutter joint or failed wall joint can affect more than one home. For a flat in Bankside, check the lease for who looks after the outside.
Big or small, you get the same one-year guarantee.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
What we do, step by step
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes a few hours, depending on the number of joints and the access from start to finish. In a London area like Bankside, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- We look at where the water is coming from and check the gutter is not broken or sagging.
- The joint or trim is cleaned out and old sealant removed.
- The joint is dried, because sealant will not bond to a wet surface.
- An exterior or gutter sealant is applied to the joint.
- We check the run and clear any debris we find while we’re there.
Getting ready for the visit
- Clear items away from the joints we’re working on
- Tell us about any water getting in
- Let us know about stairs, lifts or work at height

Bankside: your questions answered
Is parking an issue for gutter sealing in Bankside?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Can you do gutter sealing in Bankside?
Yes, Bankside is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Can sealant stop a sagging gutter leaking?
Sealant won’t hold a sagging gutter. The gutter needs refixing by a gutter installer, and we will tell you if that is what we find.
When is the sealant fully cured?
Different products cure at different speeds, so please follow the time we give you.
Will you clear out my gutters?
We clean the joints we’re sealing and any debris nearby is cleared. A full gutter clean is a separate service.
Can landlords and businesses book you?
Yes. Domestic, commercial and hotel work are all part of what we do, and we are fully insured.
Do you offer different sealant colours?
In most cases you can choose. We’ll explain which colours are available and agree one before work begins.
Why deal with it now?
Replacing fascias because of open joints is usually unnecessary. A neat seal closes the gaps if the boards are sound. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in Bankside.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Surface by surface
Roofline trims
We reseal trim joints with an exterior sealant.
Gutter end caps
A leaking end cap sends water straight down the wall. It’s a quick reseal.
Walls and rooflines in Bankside
In terraces and conversions, gutters and walls are often shared with the neighbours, so it’s worth agreeing who is responsible before work starts. With historic houses such as Mansion House (about 0.6 miles north-east) nearby, there’s older building stock in the area around Bankside as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.

Do you need gutter sealing in Bankside?
When a gutter sags, its joints open. Sealing will not hold if the gutter keeps dropping, so the gutter needs refixing first.
The most common problems we see are:
- Rain getting in around a garage door
- Stop ends leaking at the end of a run
- Internal damp traced to a gutter joint
- Earlier gutter repairs that have peeled off
Managing a site like London Nautical School? Then its movement joints, gutters and trims need looking after like any other building’s.
