External mastic in West Peckham, done properly
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render. Typical jobs include panel joints letting water in and cracked joints where brick meets render or frames, across concrete & block, façade panels and copings & trims.
Older homes in small places like West Peckham may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Landlord and commercial work in West Peckham
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
What the job involves on each surface
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so its sealant has to stay flexible.
How the visit works
We bring everything the job needs with us, so there’s nothing for you to buy. Once we have agreed what’s being done, we protect the area and start. It normally takes anything from a few hours to several days, depending on the building. In a small place like West Peckham, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Mention any parking rules near the property
- Keep children and pets away from the work area
- On commercial sites, let us know about site rules

Advice
West Peckham buildings and the weather
Historic houses like Old Soar Manor (about 1.9 miles north-west) are a reminder that the area around West Peckham 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. 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.
Letting a property close to Wateringbury station? Then split movement joints are easy to miss on a rental until damp shows inside. For site and facilities teams at buildings such as Mereworth Community Primary School, larger buildings have long runs of movement joint that eventually need resealing.

Local landmarks in West Peckham
Typical jobs here are in homes near Hadlow Rural Community School and Swan on the Green pub, among other places. West Peckham’s nearest station is Wateringbury station, roughly 2.7 miles east of the centre. A little further out are Hadlow Tower museum (2 miles south-west) and Ightham Court (4.4 miles north-west).
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
West Peckham: your questions answered
Do you cover smaller places like West Peckham?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Wateringbury station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
Can I add another job to the visit?
Yes. Just list everything you need and we will quote it together.
Is there a guarantee?
Yes. Each job is guaranteed for twelve months, large or small.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
How long does external mastic take?
A typical job takes a few hours for a handful of joints, longer for a whole elevation, including preparation and clearing up. We will confirm how long when we quote.
How long does external mastic last?
It varies with how exposed the wall is and how much the joint moves. Signs to watch for are cracking, hardening and gaps at the edges.
Will the old sealant be removed?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Signs you need external mastic in West Peckham
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.
Look out for any of the following:
- Weathered mastic that no longer stretches
- Weeds or debris growing in open joints
- Joints pointed up with cement by mistake
- Leaking joints around cladding and façade panels
If you live in an older home near Church of St Dunstan, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Questions to ask before you book
- How the surfaces are prepared before sealing
- What guarantee comes with the work
- Whether they seal over old material or remove it
- What the quote includes, VAT included or not
Why deal with it now?
Water gets in through a failed movement joint and can run behind render or cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. Around West Peckham, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first.
