Wecock Farm: your questions answered
Can you do external mastic in Wecock Farm?
Yes. Our work covers London and the South East, and Wecock Farm is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
I let a flat near Rowlands Castle station. Can you help?
Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
How long will you be here?
Typically it takes anything from a few hours to several days, depending on the building. Bigger jobs take longer.
Is it OK to fill a movement joint with cement?
No, not where the gap is a movement joint. Filling it with mortar defeats its purpose, and the wall may crack nearby. We will reseal it with a flexible sealant.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Where are you based?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Do you work for hotels and businesses?
Yes. Larger jobs can be planned room by room or area by area.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
External mastic for homes and businesses in Wecock Farm
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two where mortar or filler would crack. If you have gaps where render, brick and frames meet and joints where the bead has come unstuck, we can put it right, whatever the surface.
Outbuildings, garages and conservatories around homes in places like Wecock Farm add more joints to look after. Leaks usually start at a gutter end, a garage door frame or where an extension meets the house.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or drop us an email.

- Rising or penetrating damp from elsewhere in the wall

Outside joints around Wecock Farm
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. With historic houses such as Warblington Castle (about 4.8 miles south-east) nearby, there’s older building stock in the area around Wecock Farm as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Rented homes near Rowlands Castle station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. If you look after a building such as Woodcroft Primary, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For an older house near a landmark such as The Hart Plain Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Wecock Farm is about 1 mile south-west of Horndean, in Hampshire.

Why it’s worth doing now in Wecock Farm
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. Homes in smaller places like Wecock Farm can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and give you a clear price before any work starts.

Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Keeping the joints in good condition
Aftercare is simple:
- Get split or bare joints resealed while the damage is small
- Keep movement joints as flexible joints, not mortar
- Look over the joints every year, ideally after winter
- Deal with leaking gutters that soak the joints below
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Catch it early and you reduce the risk.

What else we do in Wecock Farm
What we do, step by step
We keep the work tidy and contained to the joints we are treating, so you can carry on as normal. The job generally takes a few hours for a handful of joints, longer for a whole elevation, and we explain the cure time before we leave. A visit to Wecock Farm is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit
- Mention if the joints have been sealed before
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area
