External mastic in Robertsbridge, done properly
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. If you have weathered mastic that no longer stretches and sealant pulling away from one side of the joint, we can put it right, whatever the surface.
In a village or hamlet like Robertsbridge, older cottages and farm buildings often stand in the open, 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.

Honest limits
A few problems are outside what sealant work can do:
- Cracks in the bricks or render themselves, away from the joints
- Cutting new joints into brickwork, which is building work rather than sealant work
- Render that is blown, hollow or coming away

What external mastic looks like in Robertsbridge
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Durhamford Manor (about 3.8 miles south-east) are a reminder that the area around Robertsbridge has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Letting a property close to Robertsbridge station? Then split movement joints are easy to miss on a rental until damp shows inside. In the older streets around Robertsbridge United Reformed Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

What affects the cost of external mastic
For a quick quote, just ask. The main things that affect it are:
- Which sealant suits the joint
- How much old sealant there is and how hard it is to remove
- Working hours on commercial sites
- The number and length of the joints
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we’ll go through it with you.
Asking for a quote
To make quoting easier, please include:
- What the problem is, such as mould, gaps, leaks or cracking
- Pictures of the joints, sent by email
- Any previous sealing or DIY work
- How we’d reach the joints
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
Leave it or put it right?
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost around the joint, so the problem grows beyond the joint itself. In a small place like Robertsbridge, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why us?
- Anti-fungal silicone where joints get wet
- Arbo and Everbuild products
- Colour agreed with you before any work starts
- White, clear, grey or coloured to suit, where the product allows

DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Robertsbridge: your questions answered

Yes, Robertsbridge is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job, and we will send you a clear quote.
I let a flat near Robertsbridge station. Can you help?
Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
How do I get a quote for external mastic in Robertsbridge?
It depends on the job, so we quote each one individually. For a quick quote, ring 0345 464 0079 or email us and let us know what needs doing and where.
Is the work guaranteed?
Yes. Every job comes with our one-year guarantee.
When is the sealant fully cured?
Cure times vary by product and the conditions. Before we leave, we’ll tell you the cure time.
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.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Should I point up the gap in my brickwork?
No, not if it’s a movement joint. Pointing it stops it working and can lead to cracking. A flexible sealant is the right fill.
When to call us in Robertsbridge
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it cannot stretch and rips as the joint opens.
The problems people generally mention when they call include:
- Gaps where render, brick and frames meet
- Water getting into walls through failed joints
- Weeds or debris growing in open joints
- Movement joints with cracked, split or missing sealant
If you look after a building such as Salehurst Church of England Primary School, its movement joints, gutters and trims need looking after like any other building’s.

How the job changes by surface
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it, or one the system allows. Send us any details you have about the façade.
Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.
How the visit works
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Robertsbridge, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about parking restrictions
