- Rigid filler in a joint that should flex
How we handle external mastic in Newpound Common
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where mortar or filler would crack. If you’re dealing with plants rooting in failed movement joints and sealant pulling away from one side of the joint, we can put it right.
Outside joints can only be sealed when they’re dry, so work in Newpound Common is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Have failed joints looked at early
- Keep movement joints as flexible joints, not mortar
- Tell anyone working on the walls about the movement joints
- Check external joints each spring
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Once a joint can’t move, the wall finds another way, usually as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.

How it works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes anything from a few hours to several days, depending on the building, depending on the size of the job. In a small place like Newpound Common, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Keep children and pets away from the work area
- On commercial sites, let us know about site rules

Different surfaces, different methods
Render joints
Rendered walls have joints at beads, openings and changes of material. We reseal them with a flexible exterior sealant that suits the render colour.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. Where one has been mortared, we cut it out and reseal it with sealant.
What we are called out for in Newpound Common
Some movement joints have been pointed up with mortar, often by someone who didn’t know what it was for. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
These are the problems we’re asked about most:
- Weathered mastic that no longer stretches
- Weeds or debris growing in open joints
- Movement joints filled with mortar instead of sealant
- Cracked joints where brick meets render or frames
Managing a site like Wisborough Green Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.

External mastic in Newpound Common: local notes
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around The Parish Church of St Peter Ad Vincula, an extension built onto an older house moves differently, and the joint between them takes the strain. For landlords with property near Billingshurst station, outside joints that have cracked can let damp into a rental, so check them between lets.

Your questions about external mastic in Newpound Common
Do you cover Newpound Common for external mastic?
Yes, Newpound Common is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
I let a flat near Billingshurst station. Can you help?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
Why do you put foam in the joint first?
Backing rod controls the sealant depth and keeps it off the back of the joint. That way it bonds to the two sides only and can stretch.
What colours does the sealant come in?
We aim for a joint that suits the wall rather than one that jumps out. We’ll talk through colour options before we start, matched as closely as the range allows.
What is a movement joint?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It should be filled with flexible sealant, never mortar.
Is there a guarantee?
Yes, always. There’s a 12-month guarantee on every job, large or small.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
