Outside joints around London Beach
With historic houses such as Smallhythe Place (about 4.2 miles south) nearby, there’s older building stock in the area around London Beach as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. 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.
For site and facilities teams at buildings such as St Michael's Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing. For landlords with property near Pluckley station, outside joints that have cracked can let damp into a rental, so check them between lets.

External mastic for homes and businesses in London Beach
For buildings in London Beach, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. Common call-outs are for hard, crazed mastic that has stopped moving and panel joints letting water in, on brickwork movement joints, façade panels and concrete & block.
Older homes in small places like London Beach may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water usually gets in, and they need the right sealant at the right depth.

Questions from London Beach
Will you come out to London Beach?

When will the joints need doing again?
It varies with how exposed the wall is and how much the joint moves. Signs to watch for are cracking, hardening and gaps at the edges.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.

How it works
The work is kept neat and contained to the joints we’re treating, so you can get on with your day. The job generally takes anything from a few hours to several days, depending on the building, and we tell you how long to leave it before we go. Somewhere as small as London Beach, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- 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.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Tell us if parking is tricky
- Mention if the joints have been sealed before

When it isn’t the sealant
To be straight with you, there are a few things sealant won’t fix:
- Movement that’s more than a sealant joint can take
- Cracks in the bricks or render themselves, away from the joints
- Damp that is not coming from the joint
If you are not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer.
Surfaces we seal
- Joints between brick and frames
- Copings & trims
- Façade panels
- Brickwork movement joints
- Concrete & block
- Render & cladding joints
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.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
How to look after the new joints
So the new joints stay in good condition:
- Avoid pressure-washing directly into sealant joints
- Do not let climbing plants root in the sealant
- Act on the first splits you see
- Keep water from gutters off the wall
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.
Once a joint cannot move, the wall finds another way, often as cracks near the joint. Resealing it early helps prevent that.
How the job changes by surface
Joints between dissimilar materials
Different materials may need different primers. We prepare both faces so the sealant bonds properly.
Copings and trims
Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible.
Do you need external mastic in London Beach?
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.
Most people get in touch after spotting one of these:
- Hard, crazed mastic that has stopped moving
- Leaking joints around cladding and façade panels
- Movement joints with cracked, split or missing sealant
- Failed seals between different materials
Homes close to Church of St Michael include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.
