How it works
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes an hour or two for a few joints, longer for a full run. In a London area like Clapham Junction, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- We look at the gutters, fascias and trims and agree the joints to seal.
- We clean out each joint.
- The joints are dried.
- The sealant is applied and finished.
- We check our work before we leave.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Keep children and pets away from the work area
- Clear items away from the joints we are working on

Advice
Gutter sealing in Clapham Junction
It’s easy to live with a dripping gutter joint, but each shower sends water to the same place. Sealing it is quick if the gutter is otherwise in good order. We are often asked to deal with fascia boards with gaps between them and water dripping where gutter sections meet, on roofline trims, garage door frames and gutter end caps.
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.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

What affects the cost of gutter sealing
We do not publish a price list. What we look at:
- How much there is to do
- Whether the work is at height
- How many areas need sealing
- The type of sealant required
Combining jobs into one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- Pictures of the joints, sent by email
- If it’s domestic, commercial or a hotel
- If someone has resealed it before
- The problem you’ve noticed
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we’ll talk you through the work and give you a clear quote.
Do you need gutter sealing in Clapham Junction?
Water spilling over a blocked gutter is often mistaken for a leak. A blocked downpipe makes water back up so we check the cause first.
It’s worth asking for a quote if you see:
- Quick sealant fixes on gutters that didn’t last
- Stop ends leaking at the end of a run
- Open joints in fascias and soffits
- Wet patches on the wall under a gutter joint
Clapham Junction is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Your questions about gutter sealing in Clapham Junction
Can parking be tricky for a visit in Clapham Junction?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Can you do gutter sealing in Clapham Junction?
Yes. Our work covers London and the South East, and Clapham Junction is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.
Can you reach high gutters?
It depends on the access. Tell us the height and what’s around the gutter when you call 0345 464 0079 or drop us an email.
Can a leaking gutter joint be sealed?
In many cases, yes. Cleaning, drying and resealing the joint generally works. A split or warped section needs replacing.
Do you remove the old sealant?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Do you work for letting agents?
Yes. As well as householders, we work for landlords, agents, businesses and hotels.
Where are you based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
What happens if it’s left?
Sealant won’t clear a blocked downpipe. We look at what’s really happening and tell you if something else is needed. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Watch for drips in a downpour
- Keep ladders off the guttering
- Keep an eye out for wet patches below a joint
- Clear leaves and moss from the gutters
Keep the gutters clear of leaves and moss, so water drains away past the joints. Water left in a gutter tests every joint.
The sooner a gutter leak is sealed, the less water reaches the wall. We’ll let you know if the gutter needs more than sealant.

Walls and rooflines in Clapham Junction
Historic houses like Carlyle's House (about 1.4 miles north) are a reminder that the area around Clapham Junction 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. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to Clapham Welsh Presbyterian Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. Managing a site like Christ Church CofE Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.
