Gutter sealing in New Cross, done properly
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. Common call-outs are for drips from gutter joints and end caps and wet patches on the wall under a gutter joint, on garage door frames, roofline trims and uPVC fascias.
London’s terraces and conversions often share walls, gutters and downpipes with their neighbours, so one failed joint can cause damp for more than one household. For a flat in New Cross, check the lease for who looks after the outside.
The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or send us an email.

What we do, step by step
Every visit runs the same way: we check the joints, protect the area around them, do the work and tidy away. It normally takes an hour or two for a few joints, longer for a full run. In New Cross, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- First we agree which joints need sealing.
- We clean out each joint.
- We make sure everything is dry.
- We apply exterior or gutter sealant and finish it neatly.
- We check our work before we leave.
Getting ready for the visit
- Move anything stored near the joints
- Keep children and pets away from the work area
- For indoor joints, keep the area dry beforehand if you can

Related advice
New Cross questions
Is parking a problem for a job in New Cross?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Can you do gutter sealing in New Cross?
Yes. We work across London and the South East, and New Cross is part of that. You can phone 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear price.
What about gutters on a second or third storey?
Single-storey work is the most straightforward. We will confirm the access for higher gutters before we book.
Is gutter cleaning part of the job?
We clear what’s around the joints we work on. Full gutter cleaning is a separate job.
Do you seal gaps in fascias and soffits?
Yes. We seal open joints along fascias and soffits in a colour to suit.
Do you work for hotels and businesses?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Will sealing fix a sagging gutter?
Not on its own. If the gutter sags, the joints keep opening, so the brackets need fixing first.
Can tenants book the work?
Yes. Check with your landlord; we can send the quote to them too.
DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

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

What else we do in New Cross
Do you need gutter sealing in New Cross?
Sealant on fascias and trims weathers like any outdoor joint. It hardens, shrinks and splits after some years.
Any of these means the joints need attention:
- Water dripping where gutter sections meet
- Cracked sealant along roofline trims
- Water running down the wall below the gutter
- Gaps along fascia and soffit joints
If you let a flat or house near New Cross station, leaking gutter joints on a rental are best caught before they stain the walls.
Questions to ask before you book
- Whether the sealant suits the joint
- How hidden problems are handled
- How the surfaces are prepared before sealing
- What the cure time is
Landlord and commercial work in New Cross
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will give you a quote.
If you manage several properties in or around New Cross, several properties can be quoted together. Send us the addresses and the work at each, and photos by email help.
What happens if it’s left?
Sealant won’t clear a blocked downpipe. We check the cause first and tell you if something else is needed. 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 New Cross, the repair is bigger than the sealant job would have been.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
