How we handle external mastic in Dunsfold
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. We work on joints between brick and frames, concrete & block and brickwork movement joints, and people most often call us about failed sealant between panels on a façade and weeds or debris growing in open joints.
External sealant needs dry, clean surfaces, so work around Dunsfold is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Questions from Dunsfold
Do you cover smaller places like Dunsfold?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Witley station?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Will the new joint stand out?
The sealant colour is picked to suit the wall, so the joint sits quietly in the wall. There’s a wide choice of exterior colours.
Where do you work from?
We’re based in Crawley, and we work across South East England, London and Scotland.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
What information do you need?
A short description and the location, plus photos if you have them. We’ll ask anything else we need to know.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
How long will you be here?
Most jobs take anything from a few hours to several days, depending on the building. Your quote will say how long we expect yours to take.
What affects the quote in Dunsfold
We do not publish a price list, because jobs vary so much. What we look at:
- When we can work, for business premises
- Access and height
- Whether old sealant or filler has to be cut out
- The number of rooms or windows
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Access, such as stairs, a lift or height
- Roughly how big the job is
- If it’s domestic, commercial or a hotel
- Photos by email, if that’s easy
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. Whenever you are ready, call 0345 464 0079 or drop us an email.
Signs you need external mastic in Dunsfold
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.
Keep an eye out for any of the following:
- Failed seals between different materials
- Sealant pulling away from one side of the joint
- Brick movement joints where the sealant has split
- Weeds or debris growing in open joints
In the older streets around Church of St Mary and All Saints, an extension built onto an older house moves differently, and the joint between them takes the strain.
Before booking anyone
- Whether all the old sealant comes out first
- Who turns up on the day
- Which sealant they’ll use, and why
- Whether they’re fully insured
Aftercare tips
After the cure time, these simple habits help:
- Point out the joints to other trades
- Have failed joints looked at early
- Never let anyone fill a movement joint with mortar
- Keep soil, plants and ivy away from the joints
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges.
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.
External mastic in Dunsfold: local notes
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Witley station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

How it works
On the day, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before work begins. The work normally takes a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Dunsfold, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Mention any sign-in or site rules at work premises

Related advice
What the job involves on each surface
Copings and trims
A failed coping joint lets water into the top of the wall. Sealing them early saves the wall below.
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. A primer goes on where the product requires one before sealing.
Why deal with it now?
Water gets in through a failed movement joint and can run behind render or cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. Where a wall is exposed, as many are in small places like Dunsfold, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.
