How we handle external mastic in Stalisfield
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Porous or awkward surfaces are primed where the sealant needs it. Common call-outs are for gaps where render, brick and frames meet and sealant pulling away from one side of the joint, across façade panels, concrete & block and brickwork movement joints.
Around Stalisfield, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water usually gets in, and they need the right sealant at the right depth.
Every job is covered by our one-year guarantee.

Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
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.
Different surfaces, different methods
Render joints
The face of render can be soft, so a sealant that stretches easily protects the edges. Priming is done where the sealant calls for it.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. We reseal their joints with backing rod and a flexible product.
What we can’t put right
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Subsidence or other structural problems
- Cracks in the bricks or render themselves, away from the joints
- Walls that need new movement joints cut into them
If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer.
Surfaces we seal
- Façade panels
- Concrete & block

- Copings & trims
What happens on the day
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to several days, depending on the building. Somewhere as small as Stalisfield, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Keep children and pets away from the work area
- For indoor joints, keep the area dry beforehand if you can

Outside joints around Stalisfield
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Belmont House and Gardens (about 2.6 miles north-east) are a reminder that the area around Stalisfield has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
In the older streets around Church of St Mary, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Leave it or put it right?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. In a small place like Stalisfield, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will explain what it covers.

Do you need external mastic in Stalisfield?
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
These are the problems we are asked about most:
- Failed seals between different materials
- Leaking joints around cladding and façade panels
- Old sealant gone brittle and cracked
- Plants rooting in failed movement joints
For landlords with property near Charing station, split movement joints are easy to miss on a rental until damp shows inside.
