Different surfaces, different methods
Render joints
Render is weaker at the surface than brick, so a sealant that stretches easily protects the edges. Priming is done where the sealant calls for it.
Copings and trims
Coping and trim joints face rain and sun head on. We reseal them with an exterior sealant suited to the material.
External mastic in Chapel Row
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. If you’re dealing with plants rooting in failed movement joints and brick movement joints where the sealant has split, we can put it right, whatever the surface.
Around Chapel Row, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
Big or small, it’s backed by our 12-month guarantee.

Looking after it afterwards
To keep the joints looking good and working properly:
- Leave the joints unpainted unless we have said otherwise
- Get split or bare joints resealed while the damage is small
- Fix overflowing gutters above sealed joints
- Check external joints each spring
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
Why deal with it now?
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost around the joint, so the problem grows beyond the joint itself. In a small place like Chapel Row, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.

Walls and rooflines in Chapel Row
With historic houses such as Horselunges Manor (about 3.4 miles west) nearby, there’s older building stock in the area around Chapel Row as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Herstmonceux Church of England Primary School, its movement joints, gutters and trims need looking after like any other building’s. For landlords with property near Pevensey Bay station, outside joints that have cracked can let damp into a rental, so check them between lets.

How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours to a few days, depending on the length of joint and the access and we leave things clean and tidy. For a village or hamlet like Chapel Row, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about stairs, lifts or work at height
- Clear items away from the joints we are working on

I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Do you seal joints where cladding meets other materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. We pick a colour that works with both materials.
Is it OK to seal over old sealant?
No. The old sealant always comes out first, so the new sealant bonds properly.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
