External mastic for homes and businesses in Lower Stoke
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render so the line blends in. If you have cracked joints where brick meets render or frames and damp patches traced to an open external joint, we can put it right.
Older homes in small places like Lower Stoke may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

When something else is needed
A few problems are outside what sealant work can do:
- Subsidence or other structural problems
- Cracks in the bricks or render themselves, away from the joints
- Adding movement joints to masonry that has none

Common problems we fix in Lower Stoke
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
If you can see any of these, it’s time to have the joints looked at:
- Movement joints filled with mortar instead of sealant
- Damp patches traced to an open external joint
- Moss and dirt in joints with no sealant left
- Cracked joints where brick meets render or frames
Managing a site like Stoke Primary Academy? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Lower Stoke buildings and the weather
Lower Stoke is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to Church of St Peter and St Paul include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

DIY versus a professional finish
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Deal with leaking gutters that soak the joints below
- Point out the joints to other trades
- Keep movement joints as flexible joints, not mortar
- Act on the first splits you see
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
What happens on the day
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to several days, depending on the building. Somewhere as small as Lower Stoke, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- Mention any tricky access
- Mention if the joints have been sealed before
- Clear items away from the joints we’re working on

Advice
Your questions about external mastic in Lower Stoke
Will you come out to Lower Stoke?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you do external mastic in Lower Stoke?
Yes. Our work covers London and the South East, and Lower Stoke is part of that. You can call 0345 464 0079 or send us an email and let us know what needs doing.
Are you fully insured?
Yes. Full insurance covers our work.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Can a movement joint be filled with mortar?
No. Mortar locks the joint solid, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.
Can you reach joints on upper floors?
Each building is different. Tell us the height, the number of joints and what’s below them and we’ll confirm how they can be reached safely.
Will there be a smell?
Some sealants have a smell while they cure. Ventilation helps.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Why act early in Lower Stoke
A failed movement joint lets water into the wall and can run behind render or cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. Around Lower Stoke, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, call 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

Different surfaces, different methods
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so its sealant has to stay flexible.
Cladding and façade panels
If the façade has a specified sealant, that’s what we use or an approved alternative. Tell us what the building has when you get in touch.
