How we handle external mastic in Stow Maries
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two where mortar or filler would crack. If you have cracked joints where brick meets render or frames and joints where the bead has come unstuck, we can put it right, whatever the surface.
External sealant needs dry, clean surfaces, so work around Stow Maries is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
Each job carries a 12-month guarantee.

What happens on the day
The work is kept neat and contained to the joints we’re treating. The job generally takes a few hours for a handful of joints, longer for a whole elevation, and we tell you how long to leave it before we go. Somewhere as small as Stow Maries, access is often the only tricky part. 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.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints

Stow Maries questions
I let a flat near North Fambridge station. Can you help?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.
Is Stow Maries in your area for external mastic?
Yes. Our work covers London and the South East, and Stow Maries is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear quote.
How long does the job take?
It depends on the size of the job, but as a guide it takes anything from a few hours to several days, depending on the building. We will give you a better idea when we quote.
When will the joints need doing again?
That varies with the weather the wall faces, how much it moves and the sealant used. Sealant is a maintenance item, so check the joints once a year.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover Stow Maries.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
When it isn’t the sealant
New sealant can’t fix everything, and we’d rather say so up front. It won’t solve:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Damp that is not coming from the joint
- Subsidence or other structural problems
If you’re not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer.
Surfaces we seal
- Façade panels
- Concrete & block
- Copings & trims
- Joints between brick and frames
- Brickwork movement joints
- Render & cladding joints
DIY versus a professional finish
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.
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.
What external mastic looks like in Stow Maries
Compared with the north and west, the South East gets less rain, 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 Parish Church of St Mary, old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you look after a building such as Cold Norton Primary School, larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to North Fambridge station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

Leave it or put it right?
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost, so the problem grows beyond the joint itself. Around Stow Maries, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Different surfaces, different methods
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that’s happened, we rake it out and reseal it properly if the joint can be cleared.
Concrete and blockwork
Big joints in concrete need careful depth control. Backing rod sized to the joint sets it and keep the sealant to the right depth.
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Point out the joints to other trades
- Keep soil, plants and ivy away from the joints
- Act on the first splits you see
- Make sure movement joints are not pointed over
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.
