The process
Before we leave, we go over the finished joints with you. The visit itself normally takes a few hours for a handful of joints, longer for a whole elevation, depending on how much there is to do. In a small place like Upper Brailes, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about parking restrictions
- Plan for the work area to be out of bounds to pets and children

How we handle external mastic in Upper Brailes
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We take the old material out and do it properly. Typical jobs include weeds or debris growing in open joints and brick movement joints where the sealant has split, across brickwork movement joints, copings & trims and concrete & block.
Around Upper Brailes, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water usually gets in, and they need the right sealant at the right depth.
There’s a 12-month guarantee on every job, whatever its size.

Walls and rooflines in Upper Brailes
Compared with the north and west, the South East gets less rain, 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 Brailes CofE Primary School, larger buildings have long runs of movement joint that eventually need resealing.

What the job involves on each surface
Render joints
Cracks along render joints let water in behind the coat. A sound joint keeps the render dry behind and protects the render itself.
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
FAQs for Upper Brailes
Is Upper Brailes in your area for external mastic?
Yes, Upper Brailes is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or send us an email and tell us what needs doing, and we’ll send you a clear quote.
What guarantee comes with external mastic in Upper Brailes?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Can you seal joints between two different materials?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides, primed where needed.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in.
How much does external mastic cost in Upper Brailes?
Every job is different, so each one gets its own quote. For a quick quote, call 0345 464 0079 or email us and tell us what needs doing and where.
How do you reach high-level joints?
It depends on the building. We work on joints that can be reached safely. Tell us about the building and we will confirm what access is needed.
Why is there a gap in my brick wall?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It should be filled with flexible sealant, never mortar.
Signs you need external mastic in Upper Brailes
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
Any of these means the joints need attention:
- Joints where the bead has come unstuck
- Weathered mastic that no longer stretches
- Rain getting behind render or cladding at a joint
- Joints with sealant missing in places
For an older house near a landmark such as Church of St George, older walls, gutters and the joints where extensions meet them need a flexible sealant.
Before you book anyone
- What preparation is included
- How long to leave it before use
- Which sealant they’ll use, and why
- Whether VAT is included
What happens if it’s left?
Water gets in through a failed movement joint and can run behind render or cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. Around Upper Brailes, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

What we can’t put right
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Cracking across the wall rather than at a joint
- Cutting new joints into brickwork, which is building work rather than sealant work
- Loose or hollow render, which needs re-rendering
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.
