Gutter sealing in Clapham, done properly
A lot of gutter leaks come down to one tired joint. We clean out the joint, dry it and reseal it with a sealant made for guttering. If the gutter itself has failed, we say so. We work on gutter joints, garage door frames and roofline trims, and common reasons people get in touch are failed sealant on a garage door frame and open joints in fascias and soffits.
Newer London blocks are built with movement joints in brick and render, and with cladding joints sealed with mastic. Period houses have different weak points, such as gutter joints, trims and the line where an extension meets the old wall, and both kinds of building are found across London.
Every job is covered by our 12-month guarantee.

Clapham buildings and the weather
Historic houses like Carlyle's House (about 1.9 miles north-west) are a reminder that the area around Clapham has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near St Paul's Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. As a London address, Clapham can be tricky for parking: let us know about parking bays, permits or a driveway.
Clapham is about 3 miles north of Streatham, in Greater London. Anywhere in SW4, our applicators can take on gutter sealing. Clapham is one of 764 places in Greater London we cover.
Work in SW4, SW8 and SW9 works the same way as everywhere else we cover. Local streets include Grafton Square, Clapham High Street and Houghton Square, and we cover them all. Main roads around Clapham include the B224 and B303. We also cover the places around Clapham: Stockwell (1 mile east), Little Portugal (1 mile north-east), Clapham Park (1 mile south), South Lambeth (1 mile north-east) and Brixton (1 mile south-east). Further out, we also cover London (3 miles north-east), City of Westminster (3 miles north), Marylebone (4 miles north), Kensington (4 miles north-west), St Pancras (4 miles north) and Shoreditch (5 miles north-east).
Around Clapham
We work in homes and buildings around Lambeth Academy, Larkhall Park and Trinity Academy and the streets around them. There’s a railway station in Clapham itself: Clapham High Street station. Other landmarks nearby include Baynard's Castle (3.5 miles north-east) and Harrods (2.6 miles north-west). Not far away are Battersea Park Lake and Knight's Hill.
Do you need gutter sealing in Clapham?
Stop ends take pressure from water running along the gutter. If the seal fails, water escapes at the end and runs down the wall.
The problems people normally mention when they call include:
- Stop ends leaking at the end of a run
- Rain getting in around a garage door
- Water dripping where gutter sections meet
- Damp on an inside wall under a dripping gutter
For landlords with property near Clapham High Street station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

Why deal with it now?
Sealant will not clear a blocked downpipe. We check the cause first and tell you if something else is needed. 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. Dealing with it early is far simpler for homes in Clapham.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and agree the price before starting.
Why us?
- White, clear, grey or coloured to suit, where the product allows
- Colour picked to suit the job
- ARBOMaster approved applicator
- 12-month guarantee on every job

What sealant work cannot fix
A few problems are outside what sealant work can do:
- Rotten or damaged fascia boards
- Downpipes that are blocked or broken

Clapham: your questions answered
Can you do gutter sealing in Clapham?
Yes, Clapham is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing, and we’ll send you a clear quote.
I let a flat near Clapham High Street station. Can you help?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
Where are you based?
Our base is Crawley. Our area covers South East England, London and Scotland.
Is sealing fascia joints something you do?
We do. Our work is the joints and we will let you know if a board has failed.
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 will explain our choice.
Do you have insurance?
Yes. We are fully insured, and we can confirm the details when we quote.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
Landlord and commercial work in Clapham
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
If you manage several properties in or around Clapham, several properties can be quoted together. Send us the addresses and the work at each.
DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

How it works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes an hour or two for a few joints, longer for a full run, including the tidy-up. In Clapham, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- We look at where the water is coming from and check the gutter is not broken or sagging.
- Old sealant and dirt are removed from the joint.
- We make sure the joint is dry before sealing.
- 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.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Tell us about access, such as stairs, a lift or high-level joints
- Keep pets and children clear of the area while we work

Soffit joints
Soffits sit under the eaves, where joints can open up. We seal them to close the gaps.
Roofline trims
We seal the trims, not the roof. A roofer deals with the roof itself.
