About our external mastic in Egerton
Movement joints let brickwork, render and cladding expand and shrink without cracking. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. We’re often asked to deal with weeds or debris growing in open joints and damp patches traced to an open external joint, on brickwork movement joints, façade panels and copings & trims.
Around Egerton, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.
A one-year guarantee comes with the work, just as it does everywhere we cover.

How the job changes by surface
Copings and trims
Coping and trim joints face rain and sun head on. We reseal them with an exterior sealant suited to the material.
Joints between dissimilar materials
Different materials may need different primers. We prepare both faces so the sealant bonds properly.
Questions from Egerton
Do you work for landlords with property near Pluckley station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Is Egerton in your area for external mastic?
Yes, Egerton is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or send us an email and tell us what needs doing, and we will give you a clear quote.
Do you guarantee your work?
Yes: twelve months. If anything is not right with the work within the year, let us know and we will sort it.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Can you seal joints between render and window frames?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. We pick a colour that works with both materials.
Where are you based?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme.
Walls and rooflines in Egerton
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Pluckley station, split movement joints are easy to miss on a rental until damp shows inside. For site and facilities teams at buildings such as Egerton Church of England Primary School, its movement joints, gutters and trims need looking after like any other building’s. If you live in an older home near Church of St James, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

The process
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on the building. Somewhere like Egerton needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- 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.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Keep pets and children clear of the area while we work
- For indoor joints, keep the area dry beforehand if you can

From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Why deal with it now?
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Where a wall is exposed, as many are in small places like Egerton, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before any work starts, so you know where you stand.

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Wash walls gently around the sealant
- Check the sealant is paintable before painting near it
- Deal with leaking gutters that soak the joints below
- Look over the joints every year, ideally after winter
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
