About our external mastic in Royal Tunbridge Wells
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 façade panels, brickwork movement joints and concrete & block, and people most often call us about failed seals between different materials and movement joints filled with mortar instead of sealant.
Royal Tunbridge Wells mixes older houses and their gutters with newer estates of brick, render and uPVC trims. All of those joints move, so they need a flexible sealant rather than a rigid filler.
Each job carries a 12-month guarantee, whatever its size.

Royal Tunbridge Wells questions
What guarantee comes with external mastic in Royal Tunbridge Wells?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Do you cover Royal Tunbridge Wells for external mastic?
Yes, Royal Tunbridge Wells is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or send us an email and let us know what needs doing, and we’ll send you a clear quote.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Can you match the colour of my brickwork?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We pick the one that suits your wall best.
Can landlords and businesses book you?
Yes, regularly. We can quote for several properties at once.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
When will the joints need doing again?
There’s no fixed answer: sunny, exposed elevations and busy joints wear faster. Check them each year and reseal when they split or harden. Our work comes with a 12-month guarantee.
Are you insured?
Yes. Full insurance covers our work.
DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Aftercare tips
Looking after new joints is easy:
- Avoid pressure-washing directly into sealant joints
- Fix overflowing gutters above sealed joints
- Keep soil, plants and ivy away from the joints
- Never let anyone fill a movement joint with mortar
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges.
A joint that has stopped moving pushes the movement elsewhere, usually as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
External mastic in Royal Tunbridge Wells: local notes
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. Historic houses like Groombridge Place (about 3.6 miles west) are a reminder that the area around Royal Tunbridge Wells 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.
For landlords with property near Tunbridge Wells station, split movement joints are easy to miss on a rental until damp shows inside. Homes close to Parish Church of St Barnabas include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. For site and facilities teams at buildings such as St Barnabas CofE VA Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

How the visit works
When we arrive, we look over the joints with you first, so you know exactly what we are doing. We protect the surfaces around the joints before we start. The work generally takes anything from a few hours to several days, depending on the building. In Royal Tunbridge Wells, parking is rarely complicated, though it helps to know about driveways or restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Tell us if parking is tricky
- For business premises, tell us about site rules or sign-in
- Plan for the work area to be out of bounds to pets and children

What else we do in Royal Tunbridge Wells
Different surfaces, different methods
Render joints
Cracks along render joints let water in behind the coat. Resealing the joints early keeps water out and helps it last.
Copings and trims
Coping and trim joints face rain and sun head on. Each is resealed with a weatherproof, flexible sealant.
What affects the cost of external mastic
There’s no set price list, because no two jobs are the same. The quote depends on:
- How easy the joints are to reach
- How much old sealant there is and how hard it is to remove
- Working hours on commercial sites
- The type of sealant required
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- How many joints, rooms or windows are involved
- The type of property
- The address or postcode of the job
- If someone has resealed it before
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. When it suits you, phone 0345 464 0079 or send us an email.
What sealant work can’t fix
A few problems are outside what sealant work can do:
- Cracked brickwork or render that needs a builder or plasterer
- Structural movement, which needs a surveyor or engineer
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If you are not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.

What happens if it’s left?
Running new sealant over the old bead rarely lasts. New sealant does not bond well to old, weathered sealant, so the old joint is cut out fully first. Black mould and gaps in sealant do not fix themselves, and in a busy home in Royal Tunbridge Wells they get worse with every use. Replacing the sealant now is the simplest fix.
Leaving a failed joint normally makes the job bigger, not smaller. If you’re unsure, call 0345 464 0079 or drop us an email for an honest opinion and a quote.
What you get with us
- Old sealant always removed completely
