Binscombe: your questions answered
I let a flat near Farncombe station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Is Binscombe in your area for external mastic?
Yes. We work across London and the South East, and Binscombe is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.
Do you have insurance?

What’s an expansion joint in brickwork?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It should be filled with flexible sealant, never mortar.
How often do external joints need resealing?
It varies from wall to wall: sunny, exposed elevations and busy joints wear faster. A yearly look will tell you when they need doing. Every job carries our 12-month guarantee.
What is backing rod for?
The foam is closed-cell backing rod. It stops the sealant going in too deep and bonding to three sides.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme.
Can you match the colour of my brickwork?
We choose a sealant colour to suit the brick, stone or render, so the joint sits quietly in the wall. Exterior sealants come in a good range of colours.
External mastic for homes and businesses in Binscombe
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 so the joint does not stand out. We work on façade panels, joints between brick and frames and render & cladding joints, and people most often call us about weeds or debris growing in open joints and failed seals between different materials.
Older homes in small places like Binscombe may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

What happens if it’s left?
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render around the joint, so the problem grows beyond the joint itself. Around Binscombe, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

Walls and rooflines in Binscombe
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Loseley Park (about 0.7 miles north-east) nearby, there’s older building stock in the area around Binscombe as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Homes close to St John the Evangelist Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. For landlords with property near Farncombe station, outside joints that have cracked can let damp into a rental, so check them between lets.

Different surfaces, different methods
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.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so its sealant has to stay flexible.
What we are called out for in Binscombe
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
Any of these means the joints need attention:
- Brick movement joints where the sealant has split
- Rain getting behind render or cladding at a joint
- Leaking joints around cladding and façade panels
- Hard, crazed mastic that has stopped moving
Schools such as Loseley Fields Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.
What your quote should include
- What product goes in the joint
- Whether they seal over old material or remove it
- How the joint is cleaned and prepared
- Whether they’re fully insured
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Wash walls gently around the sealant
- Look over the joints every year, ideally after winter
- Never let anyone fill a movement joint with mortar
- Ask before painting over external sealant
Only paint over the joint if we’ve confirmed the sealant can take paint. Many exterior sealants aren’t designed to be painted.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established.
