About our external mastic in Butler's Cross
Low-level joints can normally be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we will confirm what’s needed to reach them safely. We’re often asked to deal with rigid filler in a joint that should flex and weeds or debris growing in open joints, across concrete & block, copings & trims and joints between brick and frames.
Outside joints can only be sealed when they’re dry, so work in Butler's Cross is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Every job comes with a 12-month guarantee, wherever you are in Buckinghamshire.

What happens on the day
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on the building in most cases. In a small place like Butler's Cross, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- Mention any tricky access
- Keep children and pets away from the work area
- Clear the area around the work

Advice
Honest limits
We’d rather tell you now than do work that won’t last, so these are the limits:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Cracked brickwork or render that needs a builder or plasterer
- Failed render or damaged cladding panels
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Avoid pressure-washing directly into sealant joints
- Show decorators and builders where the movement joints are
- Have failed joints looked at early
- Keep soil, plants and ivy away from the joints
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.

Why act early in Butler's Cross
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. Older cottages and farmhouses around Butler's Cross can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins.

External mastic in Butler's Cross: local notes
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as Church of St Peter and St Paul, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Schools such as John Colet School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. If you let a flat or house near Little Kimble station, split movement joints are easy to miss on a rental until damp shows inside.

Different surfaces, different methods
Render joints

Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.
