About our external mastic in Peckham Bush
Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. If you have hard, crazed mastic that has stopped moving and panel joints letting water in, we can help, whatever the surface.
Older homes in small places like Peckham Bush may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in.
Big or small, it’s backed by our 12-month guarantee in Peckham Bush and across Kent.

Different surfaces, different methods
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. A flexible sealant bridges the two so the movement is taken up.
Render joints
Rendered walls have joints at beads, openings and changes of material. They’re resealed in a sealant that suits the render.
Common problems we fix in Peckham Bush
Some movement joints have been pointed up with mortar, often by someone who didn’t know what it was for. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Most people get in touch when they notice something like this:
- Gaps where render, brick and frames meet
- Rigid filler in a joint that should flex
- Rain getting behind render or cladding at a joint
- Failed sealant between panels on a façade
If you let a flat or house near Yalding station, outside joints that have cracked can let damp into a rental, so check them between lets.
Before you book anyone
- Is VAT in the price?
- Whether they seal over old material or remove it
- Whether you can choose the colour
- What insurance they hold
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Clear growth from the base of walls and joints
- Deal with leaking gutters that soak the joints below
- Ask before painting over external sealant
- Keep movement joints as flexible joints, not mortar
Don’t let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
Quotes for external mastic in Peckham Bush
Call for a quick quote. The main things that affect it are:
- How much old sealant there is and how hard it is to remove
- Access and height

- Any mould that needs treating
Combining jobs into one visit is usually more efficient than separate visits. You will get one clear quote for the whole job.
What to tell us for a quote
Photos by email are helpful but not essential. Try to tell us:
- Photos by email, if that’s easy
- The problem you’ve noticed
- Any previous sealing or DIY work
- Roughly how big the job is
We quote each job on its own. Just phone 0345 464 0079 or send us an email with the details and send photos if you have them.
When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Failed render or damaged cladding panels
- Movement that’s more than a sealant joint can take
- Cracking across the wall rather than at a joint
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly before you book.

Leave it or put it right?
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. In a small place like Peckham Bush, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

Peckham Bush questions
Do you work for landlords with property near Yalding station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can phone 0345 464 0079 or email us with the details for a clear quote.
Do you cover Peckham Bush for external mastic?
Yes. Our work covers London and the South East, and Peckham Bush is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.
Do you guarantee your work?
Yes. Each job is guaranteed for twelve months, wherever you are.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Do you seal joints where cladding meets other materials?
Yes. Different materials move at different rates, so a flexible sealant is needed where they meet. The sealant is matched to both sides.
What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for a handful of joints, longer for a whole elevation and we leave things clean and tidy. Somewhere as small as Peckham Bush, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- Mention any tricky access
- Let us know if you’ve seen damp or leaks
- For indoor joints, keep the area dry beforehand if you can

External mastic in Peckham Bush: local notes
Historic houses like Old Soar Manor (about 3.8 miles north-west) are a reminder that the area around Peckham Bush 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. 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.
For site and facilities teams at buildings such as East Peckham Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For an older house near a landmark such as Church of the Holy Trinity, an extension built onto an older house moves differently, and the joint between them takes the strain.
