About our external mastic in Ewhurst Green
On houses, flats and commercial buildings across Ewhurst Green, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. We work on brickwork movement joints, façade panels and concrete & block, and people most often call us about weeds or debris growing in open joints and joints where the bead has come unstuck.
External sealant needs dry, clean surfaces, so work around Ewhurst Green is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
Your job is guaranteed for a year, as with all our work.

What we cannot put right
We will always be straight with you, so here’s what sealant can’t fix:
- Adding movement joints to masonry that has none
- Cracking across the wall rather than at a joint
- Subsidence or other structural problems
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think before you book.
Surfaces we seal
- Render & cladding joints
- Joints between brick and frames
- Façade panels
- Concrete & block
- Brickwork movement joints
- Copings & trims
Signs you need external mastic in Ewhurst Green
If plants are growing out of a joint, the sealant has usually failed or was never there. Roots and dirt hold water against the wall and speed up the damage.
The most common problems we see are:
- Rigid filler in a joint that should flex
- Gaps where render, brick and frames meet
- Failed sealant between panels on a façade
- Weathered mastic that no longer stretches
If you live in an older home near Church of St Peter and St Paul, an extension built onto an older house moves differently, and the joint between them takes the strain.

What happens on the day
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the job takes a few hours for a handful of joints, longer for a whole elevation in most cases. In a small place like Ewhurst Green, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- We clean both faces of the joint and prime them where the product calls for it.
- 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.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Tell us if parking is tricky
- Try not to wet indoor joints just before the visit

Ewhurst Green buildings and the weather
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.
If you look after a building such as Ewhurst CofE Aided Infant School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you let a flat or house near Ockley station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Aftercare tips
So the new joints stay in good condition:
- Point out the joints to other trades
- Fix overflowing gutters above sealed joints
- Look over the joints every year, ideally after winter
- Keep soil, plants and ivy away from the joints
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
Why deal with it now?
Sealing over the top of old mastic does not hold for long. The new layer can’t bond properly to old, weathered material, so we always take the old sealant out. Where a wall is exposed, as many are in small places like Ewhurst Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why us?
- Any old sealant cut out fully, not covered over
- We leave the area clean and tidy
- Colour agreed with you before we start
- Rated 4.9 stars on Google

Common questions in Ewhurst Green
Is Ewhurst Green in your area for external mastic?
Yes. Our work covers London and the South East, and Ewhurst Green is part of that. You can phone 0345 464 0079 or send us an email and let us know what needs doing.
Do you cover smaller places like Ewhurst Green?
Yes. Ewhurst Green is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Can you seal over the old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses and we’re fully insured.
How long does external mastic last?
There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. Check them each year and reseal when they split or harden. Our work comes with a 12-month guarantee.
Will the new joint stand out?
We choose a sealant colour to suit the brick, stone or render so the joint blends in. There’s a wide choice of exterior colours.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint.
