About our external mastic in Tokers Green
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Porous or awkward surfaces are primed where the sealant needs it. We work on render & cladding joints, brickwork movement joints and copings & trims, and people most often call us about rain getting behind render or cladding at a joint and sealant pulling away from one side of the joint.
External sealant needs dry, clean surfaces, so work around Tokers Green is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. 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.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
Why it’s worth doing now in Tokers Green
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. In a small place like Tokers Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first.

The process
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes anything from a few hours to several days, depending on the building. Somewhere like Tokers Green 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.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
How to prepare
- Let us know about stairs, lifts or work at height
- Try not to wet indoor joints just before the visit
- For business premises, tell us about site rules or sign-in

How the job changes by surface
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant so neither cracks the other.
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep water from gutters off the wall
- Walk round the building once a year and look at the joints
- Have failed joints looked at early
- Leave the joints unpainted unless we’ve said otherwise
Do not let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.
Common questions in Tokers Green
Is Tokers Green in your area for external mastic?
Yes, Tokers Green is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or send us an email and let us know what needs doing.
I let a flat near Tilehurst station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
How do you reach high-level joints?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher work, tell us about the building and we’ll confirm what’s needed.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Can you quote for more than one area?
Yes, we can. More than one area can be quoted together.
Can a movement joint be filled with mortar?
No. A mortar-filled joint can’t move, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.

Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.

What we’re called out for in Tokers Green
The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
Most people get in touch when they notice something like this:
- Joints pointed up with cement by mistake
- Weeds or debris growing in open joints
- Hard, crazed mastic that has stopped moving
- Failed sealant between panels on a façade
Schools such as Kidmore End Church of England Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Questions to ask before you book
- What happens if the job turns out different
- Is VAT in the price?
- Is the old sealant removed completely?
- How the surfaces are prepared before sealing
External mastic in Tokers Green: local notes
With historic houses such as Mapledurham House (about 1.9 miles west) nearby, there’s older building stock in the area around Tokers Green as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. 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.
If you let a flat or house near Tilehurst station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. Homes close to Church of St John the Baptist include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.
