External mastic in Bobbing, done properly
Getting the depth right is half the job. 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. We work on brickwork movement joints, copings & trims and façade panels, and the jobs we see most are brick movement joints where the sealant has split and weathered mastic that no longer stretches.
Somewhere as small as Bobbing, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
A one-year guarantee comes as standard.

Why act early in Bobbing
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, so it pays to do it properly once. Around Bobbing, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.

When something else is needed
To be straight with you, some problems need a different trade:
- Movement that’s more than a sealant joint can take
- Walls that need new movement joints cut into them
- Loose or hollow render, which needs re-rendering
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.
What we seal
- Concrete & block
- Brickwork movement joints
- Façade panels
- Render & cladding joints
- Joints between brick and frames
- Copings & trims
When to call us in Bobbing
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, and it tears off the sides.
These are the problems we are asked about most:
- Joints with sealant missing in places
- Sealant that has lost its bond to the brick or render
- Water getting into walls through failed joints
- Failed sealant between panels on a façade
If you live in an older home near Church of St Bartholomew, an extension built onto an older house moves differently, and the joint between them takes the strain.

What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a handful of joints, longer for a whole elevation. Somewhere as small as Bobbing, 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.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Clear the area around the work
- Where the joints are inside, avoid wetting them before we arrive

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Keep high-pressure jets off the joints
- Show decorators and builders where the movement joints are
- Never let anyone fill a movement joint with mortar
- Ask before painting over external sealant
Do not paint over the new sealant unless we have said the product is paintable. Many exterior sealants aren’t designed to be painted, and paint can crack as the joint moves.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.

Walls and rooflines in Bobbing
Bobbing is within about 3 miles of 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Newington station, split movement joints are easy to miss on a rental until damp shows inside. Schools such as Grove Park Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

FAQs for Bobbing
Do you cover smaller places like Bobbing?
Yes. Bobbing is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Newington station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
Where do you work from?

Can I add another job to the visit?
Of course. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
What is backing rod for?
Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back.
Can you match the colour of my brickwork?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render so the joint doesn’t draw the eye.
Do you have insurance?
Yes. We’re fully insured for domestic and commercial work.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we’re using and why.

What else we do in Bobbing
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
