External mastic for homes and businesses in Faygate
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where mortar or filler would crack. Typical jobs include failed sealant between panels on a façade and moss and dirt in joints with no sealant left, across render & cladding joints, concrete & block and brickwork movement joints.
Somewhere as small as Faygate, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
A one-year guarantee comes as standard.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Aftercare tips
How long the joints last depends on use and care. We suggest:
- Avoid pressure-washing directly into sealant joints
- Deal with leaking gutters that soak the joints below
- Point out the joints to other trades
- Keep soil, plants and ivy away from the joints
Keep pressure washers away from the sealant. High-pressure water can lift the edges over time.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
FAQs for Faygate
I let a flat near Faygate station. Can you help?
Yes. We work for letting agents and landlords as well as householders. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Is Faygate within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Is it OK to fill a movement joint with cement?
No. Mortar locks the joint solid, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.
How often do external joints need resealing?
It varies from wall to wall: joints on exposed walls or with a lot of movement age sooner. Check them each year and reseal when they split or harden. Every job carries our one-year guarantee.
How do you reach high-level joints?
That depends on how high the joints are and the ground below. Ground-floor joints are simple; for higher ones, send details and we’ll confirm the access.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
How do I get a quote for external mastic in Faygate?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.

Walls and rooflines in Faygate
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 an older house near a landmark such as St Francis' Church, 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 Holy Trinity CofE Secondary School, its movement joints, gutters and trims need looking after like any other building’s.

Do you need external mastic in Faygate?
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and rips as the joint opens.
Any of these means the joints need attention:
- Movement joints with cracked, split or missing sealant
- Joints pointed up with cement by mistake
- Cracked joints where brick meets render or frames
- Panel joints letting water in
If you let a flat or house near Faygate station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

The process
When we arrive, we start by going over the job with you. We protect the surfaces around the joints before any work begins. The work normally takes anything from a few hours to several days, depending on the building. Somewhere like Faygate needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- Clear items away from the joints we are working on
- Keep children and pets away from the work area
- Where the joints are inside, avoid wetting them before we arrive

How the job changes by surface
Render joints
The face of render can be soft, so a sealant that stretches easily protects the edges. Priming is done where the sealant calls for it.
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.
