External & façade joints in Plaistow, Greater London
Professional external mastic in and around Plaistow, with old sealant always removed completely and a 12-month guarantee.
- Water getting into walls through failed joints
- Movement joints filled with mortar instead of sealant
- Brick movement joints where the sealant has split
Aftercare tips
To keep the joints looking good and working properly:
- Show decorators and builders where the movement joints are
- Check the sealant is paintable before painting near it
- Make sure movement joints are not pointed over
- Keep soil, plants and ivy away from the joints
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established.
External mastic in Plaistow, done properly
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement. If you have weeds or debris growing in open joints and movement joints with cracked, split or missing sealant, we can help, whatever the surface.
Working on the outside of a London home means planning access: shared paths, upper floors and parking. For a home in Plaistow, tell us how high the joints are and how to reach the back of the building.
Big or small, you get the same 12-month guarantee.

What’s an expansion joint in brickwork?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It’s sealed with a flexible sealant, not mortar.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses, and we’re fully insured.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
Can you seal joints between two different materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. We pick a colour that works with both materials.
Why deal with it now?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Plaistow, the repair is bigger than a sealant job.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first.

Outside joints around Plaistow
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. London terraces and converted houses often share gutters, downpipes and walls, so check who is responsible for the outside before booking.
For site and facilities teams at buildings such as Burnt Ash Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Plaistow is in London, so parking needs planning: let us know about parking bays, permits or a driveway. Letting a property close to Sundridge Park station? Then split movement joints are easy to miss on a rental until damp shows inside.

What happens on the day
All our tools and materials come with us in the van. After a quick look at the joints together, we protect the area and start. Most jobs take anything from a few hours to several days, depending on the building. For a job in Plaistow, parking and access are the things to plan: let us know about parking, the floor we will be working on and any lift or shared entrance.
- 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.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Clear items away from the joints we are working on
- Tell us about any previous sealing or DIY attempts
- Mention any leaks or damp you’ve noticed
