External & façade joints in St. Ebbes, Oxfordshire
We cover St. Ebbes for sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly.
- Movement joints filled with mortar instead of sealant
- Plants rooting in failed movement joints
- Damp patches traced to an open external joint
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
External mastic for homes and businesses in St. Ebbes
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing. We work on copings & trims, render & cladding joints and joints between brick and frames, and the jobs we see most are sealant that has lost its bond to the brick or render and brick movement joints where the sealant has split.
In a smaller place like St. Ebbes, some homes face open ground, so exposed walls and rooflines take more wind-driven rain. That is where gutter joints and wall joints tend to fail first.
Whatever the size of the job, you get the same 12-month guarantee.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Act on the first splits you see
- Deal with leaking gutters that soak the joints below
- Never let anyone fill a movement joint with mortar
- Walk round the building once a year and look at the joints
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.
St. Ebbes questions
Is St. Ebbes within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Oxford station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
What’s an expansion joint in brickwork?
Walls move with heat, cold and moisture, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
How do I get a quote for external mastic in St. Ebbes?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
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 pick the one that suits your wall best so it doesn’t stand out.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator.
Signs you need external mastic in St. Ebbes
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
Look out for these signs:
- Failed sealant between panels on a façade
- Brick movement joints where the sealant has split
- Water getting into walls through failed joints
- Plants rooting in failed movement joints
If you look after a building such as Oxford Media & Business School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

How it works
The work is kept neat and contained to the joints we are treating. Expect the work to take anything from a few hours to several days, depending on the building, and we tell you how long to leave it before we go. Parking around St. Ebbes is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- 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
- Move anything stored near the joints
- Mention any parking rules near the property
- For business premises, tell us about site rules or sign-in

What happens if it’s left?
Running new sealant over the old bead rarely lasts. New sealant doesn’t bond well to old, weathered sealant, so we always take the old sealant out. In a smaller place like St. Ebbes, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.

Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
External mastic in St. Ebbes: local notes
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. With historic houses such as Holywell Manor (about 0.7 miles north-east) nearby, there’s older building stock in the area around St. Ebbes as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
For landlords with property near Oxford station, split movement joints are easy to miss on a rental until damp shows inside. Homes close to St Ebbe's Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

What we can’t put right
New sealant can’t fix everything, and we will tell you before we start. It will not solve:
- Render that’s blown, hollow or coming away
- Cutting new joints into brickwork, which is building work rather than sealant work
- Damp that is not coming from the joint
