External mastic in Saddlescombe, done properly
We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing and we use one wherever it does. If you have cracked joints where brick meets render or frames and plants rooting in failed movement joints, we can help, whatever the surface.
Around Saddlescombe, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Look over the joints every year, ideally after winter
- Fix overflowing gutters above sealed joints
- Leave the joints unpainted unless we have said otherwise
- Act on the first splits you see
Only paint over the joint if we’ve confirmed the sealant can take paint. Many exterior sealants aren’t designed to be painted and spoil the finish.
Act while the splits are small. Then it’s a straightforward cut-out and reseal before water has had years to get in.
Saddlescombe: your questions answered
Can you do external mastic in Saddlescombe?
Yes. Our work covers London and the South East, and Saddlescombe is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing.
Will you come out to Saddlescombe?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is there a guarantee?
Yes. All our work carries a one-year guarantee.
Do you use backing rod?
The foam is closed-cell backing rod. It stops the sealant going in too deep and bonding to three sides.
How do you reach high-level joints?
Each building is different. Send us pictures and a rough idea of the height, and we’ll confirm what access is needed.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Can you seal joints between render and window frames?
Yes. Materials like render, brick, metal and uPVC all move differently, so a flexible sealant is needed where they meet. The sealant is matched to both sides.
Can landlords and businesses book you?
Yes. We work in homes, commercial premises and hotels, and we’re fully insured.
DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
For landlords 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.
For anyone letting property in or around Saddlescombe, several properties can be quoted together. Send us the addresses and the work at each.
Why it’s worth doing now in Saddlescombe
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. Too stiff a sealant can pull at the edges and break them. In a small place like Saddlescombe, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

- Old sealant and any debris are cut and raked out.

What external mastic looks like in Saddlescombe
With historic houses such as Portslade Manor (about 3.3 miles south) nearby, there’s older building stock in the area around Saddlescombe as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. 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.
If you let a flat or house near Hassocks station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. In the older streets around The Church of the Holy Trinity, an extension built onto an older house moves differently, and the joint between them takes the strain.

Surface by surface
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. We choose the product to suit.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that is happened, we rake it out and reseal it properly.
