- Rain getting behind render or cladding at a joint
- Panel joints letting water in
- Sealant pulling away from one side of the joint
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Keep soil, plants and ivy away from the joints
- Look over the joints every year, ideally after winter
- Point out the joints to other trades
- Ask before painting over external sealant
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick.
External mastic in Terling, done properly
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. If you have movement joints filled with mortar instead of sealant and failed seals between different materials, we can put it right, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Terling is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Your job is guaranteed for a year, as with all our work.

What affects the cost of external mastic
Every job gets its own quote. These are the things that affect it:
- The number and length of the joints
- When we can work, for business premises
- Which sealant suits the joint
- How many rooms, windows or areas are involved
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
What we need to know
When you call or email, it’s useful to know:
- Whether it has been sealed before
- If it’s domestic, commercial or a hotel
- Any access issues, like height or stairs
- How many joints, rooms or windows are involved
We quote each job on its own, so the first step is telling us about yours. Simply call 0345 464 0079 or send us an email and describe the job.
Different surfaces, different methods
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it and keep the sealant to the right depth.
Copings and trims
Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible year round.

Terling questions
Can you help a landlord with a rental near Hatfield Peverel station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.
Can you do external mastic in Terling?
Yes, Terling is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job.
Should I point up the gap in my brickwork?
No. Rigid materials can’t move with the wall, so the joint stops doing its job. If it has already been filled, we can usually cut it out and reseal it.
Is the work guaranteed?
Yes, for a year. If anything is not right with the work within the year, let us know and we’ll sort it.
How often do external joints need resealing?
There’s no fixed answer: sunny, exposed elevations and busy joints wear faster. A yearly look will tell you when they need doing. Our work comes with a one-year guarantee.
How do you reach high-level joints?
It depends on the height and the site. Low-level joints are straightforward; for higher ones, send details and we will confirm the access.
Can you quote for more than one area?
Yes. More than one area can be quoted together.
Will the new joint stand out?
The sealant colour is picked to suit the wall. Exterior sealants come in a good range of colours.
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
External mastic in Terling: local notes
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Hatfield Peverel station, split movement joints are easy to miss on a rental until damp shows inside. Managing a site like Terling Church of England Voluntary Aided Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you live in an older home near United Reformed Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Advice
Why deal with it now?
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. In a small place like Terling, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Call for a quick quote and we will explain what it covers.
