External & façade joints in Lower Shiplake, Oxfordshire
Problem with your movement joints in Lower Shiplake? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Rain getting behind render or cladding at a joint
- Brick movement joints where the sealant has split
- Old sealant gone brittle and cracked
How we handle external mastic in Lower Shiplake
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. We pick a colour that sits well with the wall so the joint doesn’t stand out. Common call-outs are for cracked joints where brick meets render or frames and failed sealant between panels on a façade, across brickwork movement joints, concrete & block and copings & trims.
Older homes in small places like Lower Shiplake may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in, and they need the right sealant at the right depth.
A 12-month guarantee comes as standard.

Common problems we fix in Lower Shiplake
Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
Most people get in touch when they notice one of these:
- Weeds or debris growing in open joints
- Rigid filler in a joint that should flex
- Movement joints with cracked, split or missing sealant
- Failed seals between different materials
For landlords with property near Shiplake station, outside joints that have cracked can let damp into a rental, so check them between lets.

Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Fix overflowing gutters above sealed joints
- Get split or bare joints resealed while the damage is small
- Show decorators and builders where the movement joints are
- Don’t let climbing plants root in the sealant
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges and let water in behind.
A joint that has stopped moving pushes the movement elsewhere, generally as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
Questions from Lower Shiplake
Do you cover Lower Shiplake for external mastic?
Yes, Lower Shiplake is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear price.
Is Lower Shiplake within the area you cover?
Yes, Lower Shiplake is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint.
How much does external mastic cost in Lower Shiplake?
We don’t 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 work begins.
Should I point up the gap in my brickwork?
No. Rigid materials cannot move with the wall. Where a joint has been mortared, it can often be raked out and sealed properly.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Why it’s worth doing now in Lower Shiplake
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Older cottages and farmhouses around Lower Shiplake can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we’ll go through it with you.

How we quote for external mastic
The price is agreed before any work begins. It’s based on:
- The number of rooms or windows
- Mould in or behind the old joints
- The old material and how stubborn it is
- The number and length of the joints
Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.

DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
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.

Lower Shiplake buildings and the weather
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Greenlands (about 3.6 miles north) are a reminder that the area around Lower Shiplake has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
Managing a site like Shiplake Church of England School? Then its movement joints, gutters and trims need looking after like any other building’s. For an older house near a landmark such as Church of St Mary, an extension built onto an older house moves differently, and the joint between them takes the strain.

What the job involves on each surface
Concrete and blockwork
The face of concrete or block is often dusty, so preparation is key. We prime where the sealant needs it before sealing.
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. We reseal them with an exterior sealant suited to the material.
