About our external mastic in Bayworth
For buildings in Bayworth, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean joint faces and the right depth. We work on joints between brick and frames, render & cladding joints and brickwork movement joints, and common reasons people get in touch are sealant that has lost its bond to the brick or render and movement joints with cracked, split or missing sealant.
In a village or hamlet like Bayworth, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
Big or small, it’s backed by our 12-month guarantee.

Signs you need external mastic in Bayworth
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
The most common problems we see are:
- Hard, crazed mastic that has stopped moving
- Rigid filler in a joint that should flex
- Weeds or debris growing in open joints
- Leaking joints around cladding and façade panels
For site and facilities teams at buildings such as Sunningwell Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing.
Questions to ask before you book
- How long the guarantee is
- Whether all the old sealant comes out first
- What the quote includes, VAT included or not
- Who does the work, and how experienced they are
Leave it or put it right?
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. Around Bayworth, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts.

Walls and rooflines in Bayworth
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Appleton Manor (about 3.5 miles west) are a reminder that the area around Bayworth has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Letting a property close to Radley station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. For an older house near a landmark such as Church of St Leonard, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Bayworth: your questions answered
Do you cover smaller places like Bayworth?
Yes, Bayworth is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Radley station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or email us with the details for a clear quote.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Is there a guarantee?
Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you.
When will the joints need doing again?
That depends on the wall, the weather and the movement. Look for splits, hardening or edges coming away and have them redone then.
Honest limits
We won’t take on work that won’t last, so these are the limits:
- Rising or penetrating damp from elsewhere in the wall
- Loose or hollow render, which needs re-rendering
- Subsidence or other structural problems
If you’re not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.

What else we do in Bayworth
Landlords, agents and businesses in Bayworth
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
We regularly work with letting and managing agents. Tell us the address, the job and how access works.
DIY versus a professional finish
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.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Don’t let climbing plants root in the sealant
- Walk round the building once a year and look at the joints
- Leave the joints unpainted unless we have said otherwise
- Keep water from gutters off the wall
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead and let water in behind.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
What we do, step by step
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on the building. Somewhere as small as Bayworth, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Plan for the work area to be out of bounds to pets and children
- For indoor joints, keep the area dry beforehand if you can
