Roofline trims
We reseal trim joints with an exterior sealant suited to the material.
How we handle gutter sealing in Telegraph Hill
Our work covers gutter joints and end caps as well as fascias and soffits plus roofline trims and garage door frames. It’s joint work rather than new guttering. We work on gutter end caps, soffit joints and roofline trims, and the jobs we see most are garage door frames letting rain in and water dripping where gutter sections meet.
Working on the outside of a London home means planning access: shared paths, upper floors and parking. For a home in Telegraph Hill, tell us how high the joints are and how to reach the back of the building.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

When to call us in Telegraph Hill
Leaves and moss hold water in the gutter. Water that can’t drain works its way through a weak joint and drips through.
These are the problems we are asked about most:
- Garage door frames letting rain in
- Water dripping where gutter sections meet
- Wet patches on the wall under a gutter joint
- End caps that drip every time it rains
Homes close to St Catherine's Hatcham include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.
What your quote should include
- When the joint can take water or movement
- Is the old sealant removed completely?
- What preparation is included
- What insurance they hold

Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Keep an eye out for wet patches below a joint
- Watch for drips in a downpour
- Don’t lean ladders against the gutter itself
- Have sagging gutters refixed early
While checking gutters, glance at the fascia joints too. Splits are easier to seal early.
The sooner a gutter leak is sealed, the less water reaches the wall. We will let you know if the gutter needs more than sealant.

Gutter sealing in Telegraph Hill: local notes
With historic houses such as Queen's House (about 2 miles north-east) nearby, there’s older building stock in the area around Telegraph Hill as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. In terraces and conversions, gutters and walls are often shared with the neighbours, so it’s worth agreeing who is responsible before work starts.
As a London address, Telegraph Hill can be tricky for parking: let us know about parking bays, permits or a driveway. Schools such as Haberdashers' Hatcham College are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

Telegraph Hill: your questions answered

Is parking an issue for gutter sealing in Telegraph Hill?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned.
Will you clear out my gutters?
The joints we seal are cleaned out and any debris nearby is cleared. A full gutter clean is a separate service.
Do you come to Telegraph Hill?
Yes. We cover Telegraph Hill, as part of our work across South East England, London and Scotland. To book, call 0345 464 0079 or drop us an email.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from an hour or two to a few hours, and the area is left clean. In Telegraph Hill, 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.
- First we trace the drip and check the gutter isn’t damaged.
- The old sealant and dirt are cleaned out of the joint.
- The joint is dried before sealing.
- We seal the joint with a sealant made for gutters.
- The gutter is checked and debris around the joints cleared.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Try not to wet indoor joints just before the visit
- On commercial sites, let us know about site rules
Ask for a quote
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we’ll come back to you with a quote.

Leave it or put it right?
A dripping stop end can soak the wall right through the wet months. Resealing it is a quick job before the damage spreads. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in Telegraph Hill.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, ring 0345 464 0079 or email us and we’ll give you an honest view and a quote.
