The process
When we arrive, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. Most jobs take anything from a few hours to several days, depending on the building. Somewhere like Ratley 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.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Let us know about parking restrictions
- Move anything stored near the joints

Advice
External mastic in Ratley, done properly
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render. Typical jobs include plants rooting in failed movement joints and failed sealant between panels on a façade, on façade panels, brickwork movement joints and copings & trims.
Around Ratley, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water generally gets in, and they need the right sealant at the right depth.
Each job carries a 12-month guarantee, whatever its size.

Can you do external mastic in Ratley?

How do I get a quote for external mastic in Ratley?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before any work starts.
Will the new joint stand out?
We aim for a joint that suits the wall rather than one that jumps out. Colour is agreed with you before we begin.
How long does the job take?
Typically it takes a few hours for a handful of joints, longer for a whole elevation. Larger jobs naturally take longer, and we’ll tell you how long to expect.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
How long does external mastic last?
It varies from wall to wall: sunny, exposed elevations and busy joints wear faster. Check them each year and reseal when they split or harden. Our work comes with a 12-month guarantee.
I rent my home. Can I book you?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.

What the job involves on each surface
Render joints
Rendered walls have joints at beads, openings and changes of material. We reseal them with a flexible exterior sealant that suits the render colour.
Cladding and façade panels
Panels heat up and cool down quickly, so the joints work hard every day. The sealant is chosen with that in mind.
External mastic in Ratley: local notes
With historic houses such as Upton House (about 1.3 miles south-west) nearby, there’s older building stock in the area around Ratley as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near Church of St Peter Ad Vincula, the joints between older walls, newer extensions and the roofline need a sealant that can move. In and around Ratley, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Keep movement joints as flexible joints, not mortar
- Act on the first splits you see
- Show decorators and builders where the movement joints are
- Wash walls gently around the sealant
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
Act while the splits are small. Then it’s a straightforward cut-out and reseal before water has had years to get in.
Why it’s worth doing now in Ratley
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. Where a wall is exposed, as many are in small places like Ratley, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and agree the price before starting.
