About our external mastic in Ramsnest Common
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. We work on concrete & block, brickwork movement joints and copings & trims, and the jobs we see most are movement joints with cracked, split or missing sealant and hard, crazed mastic that has stopped moving.
Around Ramsnest Common, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water normally gets in, and they need the right sealant at the right depth.
You’re covered for a year from the day we finish. If anything isn’t right with it, call 0345 464 0079 or drop us an email.

When it is not the sealant
In fairness, some problems need a different trade:
- Damp that isn’t coming from the joint
- Structural movement, which needs a surveyor or engineer
- Render that is blown, hollow or coming away
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think before booking.
Joints and surfaces we work on
- Copings & trims
- Façade panels
- Render & cladding joints
- Joints between brick and frames
- Concrete & block
- Brickwork movement joints
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Wash walls gently around the sealant
- Fix overflowing gutters above sealed joints
- Make sure movement joints are not pointed over
- Check external joints each spring
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.

Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Your questions about external mastic in Ramsnest Common
Do you work for landlords with property near Witley station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
Is Ramsnest Common within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you remove the old sealant?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few photos.
How much does external mastic cost in Ramsnest Common?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before work begins.
What’s an expansion joint in brickwork?
It’s a deliberate gap that lets the wall expand and contract without cracking. It should be filled with flexible sealant, never mortar.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses and we’re fully insured.
What we are called out for in Ramsnest Common
Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. The joint cannot move, so the wall cracks somewhere else instead.
Keep an eye out for these signs:
- Failed seals between different materials
- Moss and dirt in joints with no sealant left
- Rigid filler in a joint that should flex
- Old sealant gone brittle and cracked
Around Ramsnest Common, as everywhere, external mastic is only as good as the preparation behind it.

What external mastic looks like in Ramsnest Common
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.

Why deal with it now?
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and doesn’t last so it’s worth doing right. In a small place like Ramsnest Common, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
