Outside joints around Pinkneys Green
With historic houses such as Harleyford Manor (about 2.6 miles north-west) nearby, there’s older building stock in the area around Pinkneys Green as well as newer homes. Where a home is older, 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Church of St. James the Less, an extension built onto an older house moves differently, and the joint between them takes the strain. If you look after a building such as Courthouse Junior School, its movement joints, gutters and trims need looking after like any other building’s.

Signs you need external mastic in Pinkneys Green
Sometimes a movement joint was filled with mortar or a rigid filler by mistake. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Common reasons people contact us include:
- Leaking joints around cladding and façade panels
- Sealant pulling away from one side of the joint
- Hard, crazed mastic that has stopped moving
- Movement joints with cracked, split or missing sealant
If you let a flat or house near Furze Platt station, outside joints that have cracked can let damp into a rental, so check them between lets.
Questions to ask before you book
- Whether they seal over old material or remove it
- Which sealant they’ll use, and why
- How long to leave it before use
- What insurance they hold
DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Landlord and commercial work in Pinkneys Green
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we’re fully insured for the work.
Why it’s worth doing now in Pinkneys Green
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 an older home around Pinkneys Green, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Commercial jobs are quoted on the same basis as homes: how much there is to do, 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.

The process
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours to a few days, depending on the length of joint and the access. Parking around Pinkneys Green is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Clear items away from the joints we are working on
- Try not to wet indoor joints just before the visit

Advice
What the job involves on each surface
Concrete and blockwork
The face of concrete or block is often dusty, so preparation is key. We prime where the sealant needs it before the bead.
Cladding and façade panels
Cladding and façade panels are usually separated by sealed joints. We reseal them with a sealant suited to the panel material.
How to look after the new joints
To keep the joints looking good and working properly:
- Leave the joints unpainted unless we’ve said otherwise
- Get split or bare joints resealed while the damage is small
- Check external joints each spring
- Make sure movement joints aren’t pointed over
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
Act while the splits are small. At that stage it’s a simple cut out and reseal.
