Gutter, fascia & soffit sealing in Haggerston, Greater London
Our applicators work in Haggerston on sealing leaking gutter joints, end caps, fascias, soffits and roofline trims. Old material cut out, joints cleaned and sealed neatly and a 12-month guarantee.

Leave it or put it right?
Water from a leaking joint hits the same spot every time. Over time that can stain brickwork, mark render and encourage damp, so it’s worth sealing early. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Haggerston, the repair is bigger than the sealant job would have been.
The cost depends on the amount of work, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

About our gutter sealing in Haggerston
We seal leaking gutter joints, end caps, fascia and soffit joints plus roofline trims and garage door frames. It’s joint work, not replacing the gutter. Common call-outs are for open joints in fascias and soffits and failed sealant on a garage door frame, on roofline trims, gutter end caps and garage door frames.
In London terraces and converted houses, gutters and walls are often shared with the house next door, so a leaking gutter joint or failed wall joint can affect more than one home. In a converted house in Haggerston, it’s worth checking who is responsible for the outside before booking.
Every job comes with our 12-month guarantee.

How the job changes by surface
Gutter joints
A dripping joint does not always mean a failed gutter. Resealing is generally enough.
uPVC fascias
We seal fascia joints, not replace the boards. Damaged boards need replacing by an installer.
What happens on the day
Before we leave, we go over the finished joints with you. The work normally takes anything from an hour or two to a few hours, depending on the size of the job. In a London area like Haggerston, 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.
- We seal the joint with a sealant made for gutters and outdoor use.
- The run is checked and any debris near the joints is cleared.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Tell us if parking is tricky
- Mention if the joints have been sealed before

Advice
Walls and rooflines in Haggerston
London terraces and converted houses often share gutters, downpipes and walls, so it’s worth agreeing who is responsible before work starts. Historic houses like Sutton House (about 1.5 miles north-east) are a reminder that the area around Haggerston 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.
As a London address, Haggerston can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. Managing a site like Randal Cremer Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.

What else we do in Haggerston
Your questions about gutter sealing in Haggerston
Do you cover Haggerston for gutter sealing?
Yes, Haggerston is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or drop us an email and tell us what needs doing.
Is parking a problem for a job in Haggerston?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Do you clean gutters?
We clear what’s around the joints we work on. A full clean of the gutters isn’t part of it.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we’re using.
How long does the job take?
As a guide, most jobs take a few hours, depending on the number of joints and the access. Bigger jobs take longer, and we’ll say how long yours will take.
Do you install new fascias or gutters?
No, we reseal joints, end caps and trims. A gutter installer or roofer deals with replacement.
Do you work for landlords and businesses?
Yes. As well as householders, we work for landlords, agents, businesses and hotels.
Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, 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.
What sealant work can’t fix
To be straight with you, there are a few things sealant will not fix:
- Leaks from the roof rather than a joint
- Fascias that need replacing
- Cracked, split or warped gutter sections
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly before you book.
