About our external mastic in West Wycombe
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We take the old material out and do it properly. We work on concrete & block, joints between brick and frames and brickwork movement joints, and the jobs we see most are joints pointed up with cement by mistake and water getting into walls through failed joints.
Around West Wycombe, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.
Our work is backed for twelve months, in West Wycombe and everywhere else we cover.

Questions from West Wycombe
Do you cover West Wycombe for external mastic?
Yes, West Wycombe is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
Do you work for landlords with property near Saunderton station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
Where are you based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Can a movement joint be filled with mortar?
No, not where the gap is a movement joint. Filling it with mortar defeats its purpose. We will reseal it with a flexible sealant.

Why act early in West Wycombe
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and does not last so it’s worth doing right. Around West Wycombe, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
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. Your quote takes all of that into account.

What affects the cost of external mastic
The price is agreed before any work begins. It’s based on:
- The number of rooms or windows
- Any mould that needs treating
- The old material and how stubborn it is
- The type of sealant required
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
Helping us quote
To help us quote quickly, let us know:
- Access, such as stairs, a lift or height
- A few photos by email, if you can
- Roughly how big the job is
- If it’s domestic, commercial or a hotel
Want a quote for external mastic? Please ring 0345 464 0079 or drop us an email with a few details. You’ll know what we plan to do, and what it will cost, before any work begins.
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Work for landlords, hotels and businesses
Landlords and letting agents in West Wycombe can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for.
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.
External mastic in West Wycombe: 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. With historic houses such as West Wycombe Park House (about 0.3 miles south) nearby, there’s older building stock in the area around West Wycombe as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
If you look after a building such as West Wycombe Combined School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For landlords with property near Saunderton station, outside joints that have cracked can let damp into a rental, so check them between lets.

Surface by surface
Joints between dissimilar materials
Wherever two materials meet, they move differently. A flexible sealant bridges the two so neither cracks the other.
Cladding and façade panels
If the façade has a specified sealant, that is what we use. Send us any details you have about the façade.
What we do, step by step
The work is kept neat and contained to the joints we’re treating, so you can carry on as normal. The job normally takes a few hours to a few days, depending on the length of joint and the access, and we explain the cure time before we leave. Somewhere like West Wycombe needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can

Signs you need external mastic in West Wycombe
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.
The problems people usually mention when they call are:
- Sealant that has lost its bond to the brick or render
- Leaking joints around cladding and façade panels
- Gaps where render, brick and frames meet
- Hard, crazed mastic that has stopped moving
For an older house near a landmark such as Congregational Church, an extension built onto an older house moves differently, and the joint between them takes the strain.
