External mastic in Burford, done properly
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we will confirm what’s needed to reach them safely. We work on façade panels, brickwork movement joints and render & cladding joints, and the jobs we see most are cracked joints where brick meets render or frames and old sealant gone brittle and cracked.
Outbuildings, garages and conservatories around homes in places like Burford add more joints to look after. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.
Big or small, it’s backed by our 12-month guarantee.

Burford: your questions answered
Is Burford within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Shipton station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Do you work at height?
Each building is different. Send us pictures and a rough idea of the height, and we will confirm what access is needed.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first.
Is there a guarantee?
Yes. There’s a 12-month guarantee on every job, large or small.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
How often do external joints need resealing?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges and have them redone then.
What the job involves on each surface
Render joints
Cracks along render joints let water in behind the coat. A sound joint keeps the render dry behind.
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joints work hard every day. We choose the product to suit.
The process
The work is kept neat and contained to the area we are working on, so you can get on with your day. The job normally takes anything from a few hours to several days, depending on the building, and we explain the cure time before we leave. In a smaller place like Burford, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Where the joints are inside, avoid wetting them before we arrive
- Mention if the joints have been sealed before

Related advice
Why act early in Burford
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. In an older home around Burford, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

What affects the cost of external mastic
Every job gets its own quote. This is what makes a difference:
- How many rooms, windows or areas are involved
- Whether the work is at height
- How much old sealant there is and how hard it is to remove
- Working hours on commercial sites
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or drop us an email and we will talk you through it.
Asking for a quote
Photos by email are helpful but not essential. Try to tell us:
- Where the property is
- Access, such as stairs, a lift or height
- If someone has resealed it before
- The rough size of the job
Quotes start with a quick conversation. Describe the problem, the location and the size of the job. When it suits you, call 0345 464 0079 or send us an email.
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 matched to the joint and its conditions, and the work is guaranteed for a year.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Walls and rooflines in Burford
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Minster Lovell Hall (about 4.4 miles east) are a reminder that the area around Burford has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
In the older streets around Church of St John the Baptist, older walls, gutters and the joints where extensions meet them need a flexible sealant. If you look after a building such as Burford Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For landlords with property near Shipton station, outside joints that have cracked can let damp into a rental, so check them between lets.
