Middle Stoke buildings and the weather
Middle Stoke is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you look after a building such as Stoke Primary Academy, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

External mastic in Middle Stoke, done properly
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. We work on façade panels, joints between brick and frames and concrete & block, and people most often call us about gaps where render, brick and frames meet and weathered mastic that no longer stretches.
External sealant needs dry, clean surfaces, so work around Middle Stoke is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
All of our work is guaranteed for twelve months.

What happens if it’s left?
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner. Around Middle Stoke, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

What happens on the day
All our tools and materials come with us in the van. After a quick look at the joints together, we protect the area and start. Most jobs take anything from a few hours to several days, depending on the building. For a village or hamlet like Middle Stoke, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- For business premises, tell us about site rules or sign-in
- Let us know if you’ve seen damp or leaks
- Mention any parking rules near the property

Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Render that’s blown, hollow or coming away
- Movement that is more than a sealant joint can take

Do you need external mastic in Middle Stoke?
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
These are the problems we’re asked about most:
- Rigid filler in a joint that should flex
- Weeds or debris growing in open joints
- Weathered mastic that no longer stretches
- Brick movement joints where the sealant has split
For an older house near a landmark such as Church of St Peter and St Paul, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Middle Stoke questions
Does the coastal weather in Middle Stoke affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Is Middle Stoke in your area for external mastic?
Yes, Middle Stoke is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
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 seal joints between two different materials?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides.
Do you remove the old sealant?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
How long before the joint can be used?
That depends on the sealant used, so follow the cure time we give you when we finish.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

How the job changes by surface
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so the sealant in it must stay soft and stretchy.
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Never let anyone fill a movement joint with mortar
- Get split or bare joints resealed while the damage is small
- Look over the joints every year, ideally after winter
- Keep soil, plants and ivy away from the joints
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
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.
