External & façade joints in Bicester, Oxfordshire
Sealing brickwork movement joints, render, cladding and façade joints for householders, landlords and businesses in Bicester. Fully insured, ARBOMaster approved and guaranteed for a year.

- Failed sealant between panels on a façade
External mastic in Bicester
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We take the old material out and do it properly. Common call-outs are for movement joints with cracked, split or missing sealant and weeds or debris growing in open joints, on joints between brick and frames, copings & trims and façade panels.
Bicester mixes older houses and their gutters with newer estates of brick, render and uPVC trims. All of those joints move, so they need a flexible sealant rather than a rigid filler.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

FAQs for Bicester
Can you do external mastic in Bicester?
Yes, Bicester is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or email us with a few details of the job.
Do you work for landlords with property near Bicester North station?
Yes, we work for landlords and agents. Just phone 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
Do you work for hotels and businesses?
Yes. Larger jobs can be planned room by room or area by area.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
What colours does the sealant come in?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We pick the one that suits your wall best so the joint doesn’t draw the eye.
How do I get a quote for external mastic in Bicester?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
What is backing rod for?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. That way it bonds to the two sides only and can stretch.
How do you reach high-level joints?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher work, tell us about the building and we will confirm what’s needed.
Landlord and commercial work in Bicester
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Hotels need rooms back in use, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Why it’s worth doing now in Bicester
Done well, a resealed joint is a neat, straight line 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. Black mould and gaps in sealant do not fix themselves, and in a busy household in Bicester they spread with every shower and every downpour. Now is the easy time to put it right.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
Why us?
- Any old sealant cut out fully, not covered over
- Full insurance on every job

What happens on the day
On the day, we look over the joints with you first, so you know exactly what we are doing. Surfaces next to the work are protected before we start. The work generally takes a few hours for a handful of joints, longer for a whole elevation. A visit in Bicester needs access to the work and a place to park close by. For outside work, let us know about side access, gates and any upper-floor joints.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Clear items away from the joints we’re working on
- For business premises, tell us about site rules or sign-in
Getting a quote
We quote each job on its own, so the first step is telling us about yours. Just call 0345 464 0079 or send us an email with the details and send photos if you have them.

Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Ask before painting over external sealant
- Make sure movement joints are not pointed over
- Avoid pressure-washing directly into sealant joints
- Act on the first splits you see
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
Once a joint can’t move, the wall finds another way, usually as cracking in the brickwork or render nearby. Resealing it early helps prevent that.

Do you need external mastic in Bicester?
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, so it pulls away from the edges.
Look out for these signs:
- Sealant that has lost its bond to the brick or render
- Joints pointed up with cement by mistake
- Old sealant gone brittle and cracked
- Cracked joints where brick meets render or frames
For an older house near a landmark such as Church of St Edburg, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Walls and rooflines in Bicester
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.
Managing a site like Brookside Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For landlords with property near Bicester North station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
