External mastic in Shere
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a matching colour. If you are dealing with movement joints filled with mortar instead of sealant and cracked joints where brick meets render or frames, we can help, whatever the surface.
Around Shere, 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.
A one-year guarantee comes as standard, so you’re covered after we’ve gone.

Why act early in Shere
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together and it means sorting access once. Older cottages and farmhouses around Shere can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and agree the price before starting.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
What happens on the day
Before we leave, we go over the finished joints with you. The visit itself generally takes a few hours for a handful of joints, longer for a whole elevation, depending on how much there is to do. In a small place like Shere, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Let us know about earlier repairs to the joints
- Keep pets and children clear of the area while we work
- For indoor joints, keep the area dry beforehand if you can

Advice
FAQs for Shere
Do you cover smaller places like Shere?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Gomshall 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.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
When will the joints need doing again?
It depends on the exposure, the movement and the product. Treat it as a maintenance item and look at it yearly and reseal when it splits.
What is backing rod for?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding so the bead can stretch.
What do you need from me for a quote?
A short description and the location. If we need more, we’ll ask.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access.
Where do you work from?
We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
What the job involves on each surface
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it so the sealant is not too deep.
Render joints
Render has movement joints and stop beads that need sealing. They’re resealed in a sealant that suits the render.
Shere buildings and the weather
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 Hatchlands Park (about 2.6 miles north) nearby, there’s older building stock in the area around Shere as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
For site and facilities teams at buildings such as Shere CofE Aided Infant School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you let a flat or house near Gomshall station, split movement joints are easy to miss on a rental until damp shows inside.

Do you need external mastic in Shere?
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.
Common reasons people contact us are:
- Water getting into walls through failed joints
- Joints where the bead has come unstuck
- Rigid filler in a joint that should flex
- Panel joints letting water in
In the older streets around The Church of St James, an extension built onto an older house moves differently, and the joint between them takes the strain.
