External mastic in Billingbear
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 colour to suit. We work on render & cladding joints, concrete & block and façade panels, and the jobs we see most are cracked joints where brick meets render or frames and weathered mastic that no longer stretches.
Somewhere as small as Billingbear, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Different surfaces, different methods
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.
Joints between dissimilar materials
Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant.
What we do, step by step
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours to a few days, depending on the length of joint and the access. Somewhere like Billingbear needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked and the colour of the new sealant agreed.
- 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.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Let us know about parking restrictions
- Try not to wet indoor joints just before the visit

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Outside joints around Billingbear
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Letting a property close to Bracknell station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. In the older streets around Church of All Saints, an extension built onto an older house moves differently, and the joint between them takes the strain.

What we are called out for in Billingbear
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it cannot stretch and rips as the joint opens.
People generally contact us when they notice something like this:
- Moss and dirt in joints with no sealant left
- Sealant that has lost its bond to the brick or render
- Movement joints with cracked, split or missing sealant
- Rain getting behind render or cladding at a joint
If you look after a building such as Binfield Church of England Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
What to look for in a quote
- What product goes in the joint
- How much experience the applicator has
- What happens if they find a problem under the old sealant
- Is the old sealant removed completely?
Billingbear: your questions answered
Do you work for landlords with property near Bracknell station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.
Is Billingbear in your area for external mastic?
Yes, Billingbear is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or email us and tell us what needs doing.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses, and we’re fully insured.
How often do external joints need resealing?
There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Every job carries our 12-month guarantee.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
How long does external mastic take?
Typically it takes anything from a few hours to several days, depending on the building. Larger jobs naturally take longer, and we’ll tell you how long to expect.
Honest limits
Before booking, it’s worth knowing the limits too:
- Adding movement joints to masonry that has none
- Cracked brickwork or render that needs a builder or plasterer
- Structural movement, which needs a surveyor or engineer
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.
Surfaces we seal
- Render & cladding joints
- Brickwork movement joints
- Copings & trims
- Concrete & block
- Façade panels
- Joints between brick and frames
Leave it or put it right?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. Around Billingbear, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first.
