External mastic in Fairbourne Heath: local notes
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 Leeds Castle (about 2.3 miles north-west) are a reminder that the area around Fairbourne Heath has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
Letting a property close to Harrietsham station? Then split movement joints are easy to miss on a rental until damp shows inside. If you live in an older home near All Saints Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

External mastic for homes and businesses in Fairbourne Heath
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We strip the joint back and start again. We’re often asked to deal with movement joints with cracked, split or missing sealant and hard, crazed mastic that has stopped moving, across brickwork movement joints, façade panels and copings & trims.
Outside joints can only be sealed when they’re dry, so work in Fairbourne Heath is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
You get a one-year guarantee, the same in Fairbourne Heath as everywhere else we work.

What sealant work can’t fix
New sealant can’t fix everything, and we’ll tell you before any work starts. Sealant will not put right:
- Movement that’s more than a sealant joint can take
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Adding movement joints to masonry that has none
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think before you book.
Surfaces we seal
- Brickwork movement joints
- Concrete & block
- Render & cladding joints
- Joints between brick and frames
- Façade panels
- Copings & trims
Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
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.
Questions from Fairbourne Heath
I let a flat near Harrietsham station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Can you do external mastic in Fairbourne Heath?
Yes. Our work covers London and the South East, and Fairbourne Heath is part of that. Just call 0345 464 0079 or email us with a few details of the job.
Do you have insurance?
Yes. Full insurance covers our work.
Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
How long before the joint can be used?
Cure times vary by product and the temperature. We tell you how long to leave it before we go.
How long does the job take?
It depends on the size of the job, but as a guide it takes a few hours to a few days, depending on the length of joint and the access. We’ll give you a better idea when we quote.
What colours does the sealant come in?
The aim is a neat, even joint in a colour that suits the wall. Colour is agreed with you before we begin.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit.
Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
We work for letting agents and landlords as well as householders. Resealing between tenancies keeps a property looking cared for.
How the visit works
On the day, we look over the joints with you first. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Fairbourne Heath, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Mention any leaks or damp you’ve noticed
- Plan for the work area to be out of bounds to pets and children
- Mention any tricky access

Different surfaces, different methods
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. We reseal them with an exterior sealant suited to the material.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. Their movement joints are sealed over backing rod with a flexible sealant.

What we are called out for in Fairbourne Heath
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall and speed up the damage.
Keep an eye out for any of the following:
- Brick movement joints where the sealant has split
- Water getting into walls through failed joints
- Sealant that has lost its bond to the brick or render
- Joints pointed up with cement by mistake
Managing a site like Platts Heath Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
What your quote should include
- Which sealant they’ll use, and why
- Whether VAT is included
- When the joint can take water or movement
- Is the old sealant removed completely?
