About our external mastic in Ellesborough
For buildings in Ellesborough, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean joint faces and the right depth. If you have brick movement joints where the sealant has split and weeds or debris growing in open joints, we can help, whatever the surface.
Around Ellesborough, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water generally gets in, and they need the right sealant at the right depth.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Is Ellesborough in your area for external mastic?

I let a flat near Little Kimble station. Can you help?

Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
How long before the joint can be used?
That depends on the sealant used, so follow the cure time we give you when we finish.
What colours does the sealant come in?
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.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. Indoors, that usually means someone at home.
Where do you work from?
We work from Crawley. Our applicators cover Ellesborough, along with the rest of our area.

External mastic in Ellesborough: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Little Kimble station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you live in an older home near Church of St Peter and St Paul, older walls, gutters and the joints where extensions meet them need a flexible sealant.

What’s near Ellesborough

A little further out are Stoke Mandeville Hospital (3.1 miles north) and National Paralympic Heritage Centre (3.2 miles north). For a walk, there’s Beacon Hill and Brush Hill Local Nature Reserve.
Can I do it myself?
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What sealant work can’t fix
Before you book, it’s worth knowing the limits too:
- Walls that need new movement joints cut into them
- Cracking across the wall rather than at a joint
- Rising or penetrating damp from elsewhere in the wall
If you are not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.

- Joints between brick and frames
- Façade panels
- Concrete & block
- Render & cladding joints

The process
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Ellesborough, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
How to prepare
- Keep children and pets away from the work area
- Move anything stored near the joints
- Mention any sign-in or site rules at work premises

Why it’s worth doing now in Ellesborough
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Where a wall is exposed, as many are in small places like Ellesborough, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start.
Why us?
- Experience in homes, commercial sites and hotels
- Old sealant always removed completely
- Approved under the ARBOMaster scheme
- White, clear, grey or coloured to suit, where the product allows

Different surfaces, different methods
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.
Landlords, agents and businesses in Ellesborough
If you manage several properties in or around Ellesborough, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Common problems we fix in Ellesborough
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
Any of these means the joints need attention:
- Movement joints filled with mortar instead of sealant
- Damp patches traced to an open external joint
- Cracked joints where brick meets render or frames
- Joints with sealant missing in places
Managing a site like Great Kimble Church of England School? Then larger buildings have long runs of movement joint that eventually need resealing.
Questions to ask before booking
- The length of the guarantee
- Who turns up on the day
- Whether they seal over old material or remove it
- When the joint can take water or movement
