External Mastic in Newton Village
Problem with your movement joints in Newton Village? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Sealant pulling away from one side of the joint
- Weeds or debris growing in open joints
- Leaking joints around cladding and façade panels
What we do, step by step
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes anything from a few hours to several days, depending on the building. Outside jobs in Newton Village need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children
- Tell us about access, such as stairs, a lift or high-level joints

Related advice
External mastic for homes and businesses in Newton Village
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, and when it fails, the wall takes the strain and water finds a way in. Common call-outs are for joints where the bead has come unstuck and brick movement joints where the sealant has split, across render & cladding joints, brickwork movement joints and copings & trims.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. Newer houses need their movement joints and roofline trims kept sound.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Should I try it myself first?
A DIY attempt does not rule out a professional job. We cut it out and start again.
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.

Your questions about external mastic in Newton Village
Can you help a landlord with a rental near Shawfair station?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can go on one quote. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we will send you a clear quote.
Does the coastal weather in Newton Village affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Can you match the colour of my brickwork?
The sealant colour is picked to suit the wall. Exterior sealants come in a good range of colours.
Can you seal joints between two different materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. We pick a colour that works with both materials.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Do you use backing rod?
We fit closed-cell backing rod wherever the joint depth needs controlling. It controls the depth and stops the sealant bonding to the back.
How long does external mastic take?
A typical job takes a few hours for a handful of joints, longer for a whole elevation, including preparation and clearing up. Your quote will say how long we expect yours to take.
Where is Mr Mastic based?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
Honest limits
To be straight with you, some problems need a different trade:
- Adding movement joints to masonry that has none
- Rising or penetrating damp from elsewhere in the wall
- Failed render or damaged cladding panels
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly before you book.
Surfaces we seal
- Render & cladding joints
- Concrete & block
- Brickwork movement joints
- Copings & trims
- Façade panels
- Joints between brick and frames
What happens if it’s left?
Resealing a run of joints in one go is usually better than patching one at a time. Joints of the same age tend to fail together and it means sorting access once. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.

How we quote for external mastic
The price is agreed before any work begins. It’s based on:
- Whether the work is at height
- Any working-time requirements on site
- The amount of work
- How much old sealant there is and how hard it is to remove
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
Asking for a quote
To make quoting easier, please include:
- Where the property is
- Roughly how big the job is
- The problem you’ve noticed
- If it’s domestic, commercial or a hotel
Asking for a quote is easy: let us know what needs doing and where. A few pictures by email make the job easier to understand.
Outside joints around Newton Village
Newton Village is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. With historic houses such as Melville Castle (about 1.6 miles south) nearby, there’s older building stock in the area around Newton Village as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
If you live in an older home near Newton Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you let a flat or house near Shawfair station, outside joints that have cracked can let damp into a rental, so check them between lets. Managing a site like Dalkeith High School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Look over the joints every year, ideally after winter
- Keep high-pressure jets off the joints
- Act on the first splits you see
- Check the sealant is paintable before painting near it
Do not paint over the new sealant unless we have said the product is paintable. Many exterior sealants aren’t designed to be painted, and paint can crack as the joint moves.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
