What external mastic looks like in Little London
Historic houses like Chilworth Manor (about 2.5 miles west) are a reminder that the area around Little London 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. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Schools such as Shere CofE Aided Infant School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to Gomshall station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

About our external mastic in Little London
On houses, flats and commercial buildings across Little London, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean joint faces and the right depth. We are often asked to deal with rain getting behind render or cladding at a joint and brick movement joints where the sealant has split, across copings & trims, joints between brick and frames and brickwork movement joints.
External sealant needs dry, clean surfaces, so work around Little London is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

What affects the quote in Little London
You’ll get a clear quote before any work starts. It’s based on:
- The type of sealant required
- Working hours on commercial sites
- Mould in or behind the old joints
- The number of rooms or windows
We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.
What we need to know
To make quoting easier, let us know:
- Photos by email, if that’s easy
- What the problem is, such as mould, gaps, leaks or cracking
- Where the property is
- Any access issues, like height or stairs
If you are in Little London and need external mastic, call 0345 464 0079 or email us. Tell us what the problem is and where, and you’ll get a clear quote before we start.
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Get split or bare joints resealed while the damage is small
- Avoid pressure-washing directly into sealant joints
- Look over the joints every year, ideally after winter
- Make sure movement joints aren’t pointed over
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
The process
The work is kept neat and contained to the area we’re working on, so you can get on with your day. Expect the work to take a few hours to a few days, depending on the length of joint and the access, and we explain the cure time before we leave. Somewhere like Little London needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Let us know about stairs, lifts or work at height
- Mention if the joints have been sealed before
- Try not to wet indoor joints just before the visit

Related advice
What we’re called out for in Little London
Using the wrong sealant is another common reason. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, so it pulls away from the edges.
If you can see any of these, it’s time to have the joints looked at:
- Rigid filler in a joint that should flex
- Weathered mastic that no longer stretches
- Rain getting behind render or cladding at a joint
- Gaps where render, brick and frames meet
Homes close to Old St Peter and St Paul's Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

Little London questions
Do you cover smaller places like Little London?
Yes, Little London is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for landlords with property near Gomshall station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can go on one quote. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Is it OK to fill a movement joint with cement?
No. A mortar-filled joint can’t move, so the wall cracks somewhere else instead. Use a flexible sealant with backing rod.
Do you have insurance?
Yes. We’re fully insured for every job we do.
Can you seal over the old sealant?
No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Can you seal joints between two different materials?
Yes. Where different materials meet is one of the most common joints we seal. We use a flexible sealant suited to both surfaces.
Do the sealants smell?
Some sealants have a smell while they cure. Ventilation helps.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What sealant work cannot fix
It helps to know what we cannot do too:
- Damp that is not coming from the joint
- Cracks in the bricks or render themselves, away from the joints
- Loose or hollow render, which needs re-rendering
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think before booking.
