Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Look over the joints every year, ideally after winter
- Get split or bare joints resealed while the damage is small
- Leave the joints unpainted unless we have said otherwise
- Don’t let climbing plants root in the sealant
Keep pressure washers away from the sealant. High-pressure water can lift the edges.
Act while the splits are small. At that stage it’s a simple cut out and reseal.
External mastic in Winterbourne, done properly
A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. If you’re dealing with rain getting behind render or cladding at a joint and sealant that has lost its bond to the brick or render, we can help, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Winterbourne is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
Big or small, you get the same one-year guarantee in Winterbourne and across Kent.

Your questions about external mastic in Winterbourne
I let a flat near Selling station. Can you help?

Can you do external mastic in Winterbourne?
Yes, Winterbourne is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear quote.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We will tell you what we’re using and why.
Why do you put foam in the joint first?
Backing rod goes into deeper joints as a matter of course. It sets the sealant depth and prevents three-sided bonding so the bead can stretch.
Where is Mr Mastic based?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
How long does external mastic take?
A typical job takes anything from a few hours to several days, depending on the building, including the preparation. We will confirm how long when we quote.
How long does external mastic last?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges and have them redone then.
Can a movement joint be filled with mortar?
No. Rigid materials cannot 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.
For landlords and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
When something else is needed
We won’t take on work that won’t last, so these are the limits:
- Cracks in the bricks or render themselves, away from the joints
- Failed render or damaged cladding panels
- Adding movement joints to masonry that has none
If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer.

External mastic in Winterbourne: local notes
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Managing a site like Boughton-under-Blean and Dunkirk Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. In the older streets around Christ Church, older walls, gutters and the joints where extensions meet them need a flexible sealant. Letting a property close to Selling station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

Advice
What the job involves on each surface
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so the sealant in it must stay soft and stretchy.
Joints between dissimilar materials
Each side of the joint may need its own preparation. We prepare both faces so the sealant bonds properly.
What affects the cost of external mastic
There’s no set price list. The quote depends on:
- The old material and how stubborn it is
- Which sealant suits the joint
- How many areas need sealing
- Access and height
The cost depends on the amount of work, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts.
What to tell us for a quote
Before you ask for a quote, have a think about:
- What the problem is, such as mould, gaps, leaks or cracking
- Roughly how big the job is
- Access, such as stairs, a lift or height
- Photos by email, if that’s easy
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. When it suits you, ring 0345 464 0079 or drop us an email.
