How we handle external mastic in Slaugham
Low-level joints can generally be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what access is needed. We work on joints between brick and frames, brickwork movement joints and render & cladding joints, and common reasons people get in touch are brick movement joints where the sealant has split and rain getting behind render or cladding at a joint.
Outside joints can only be sealed when they’re dry, so work in Slaugham is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Our work is backed for twelve months.

Leave it or put it right?
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost around the joint, so the damage spreads beyond the joint. Around Slaugham, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, ring 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

Slaugham buildings and the weather
With historic houses such as Tyes Place (about 1.8 miles east) nearby, there’s older building stock in the area around Slaugham as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near Balcombe station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. If you look after a building such as Warninglid Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Slaugham: your questions answered
Do you cover smaller places like Slaugham?
Yes. Slaugham is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you help a landlord with a rental near Balcombe station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
Do you have insurance?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Is it OK to fill a movement joint with cement?
No. Rigid materials cannot move with the wall. If it has already been filled, we can normally cut it out and reseal it.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Different surfaces, different methods
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. Where one has been mortared, we cut it out and reseal it with sealant where it can be done safely.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. Their movement joints are sealed over backing rod with a flexible sealant.
What we’re called out for in Slaugham
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
The most common problems we see are:
- Sealant pulling away from one side of the joint
- Weeds or debris growing in open joints
- Joints with sealant missing in places
- Joints pointed up with cement by mistake
Homes close to St Mary's Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

How the visit works
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the work takes a few hours to a few days, depending on the length of joint and the access for a typical job. For a village or hamlet like Slaugham, the journey is planned in advance: 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.
- First, the joints are inspected and the access agreed.
- 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.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Tell us if parking is tricky
- Tell us about any water getting in
- For indoor joints, keep the area dry beforehand if you can
