What we are called out for in Cliffe
Some movement joints have been pointed up with mortar, often by someone who didn’t know what it was for. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Any of these means the joints need attention:
- Rigid filler in a joint that should flex
- Failed seals between different materials
- Joints with sealant missing in places
- Rain getting behind render or cladding at a joint
If you let a flat or house near Higham station, split movement joints are easy to miss on a rental until damp shows inside.
What your quote should include
- How the joint is cleaned and prepared
- When the joint can take water or movement
- What product goes in the joint
- What guarantee comes with the work
External mastic in Cliffe
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render. We work on façade panels, brickwork movement joints and concrete & block, and people most often call us about panel joints letting water in and weeds or debris growing in open joints.
External sealant needs dry, clean surfaces, so work around Cliffe is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
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. Everything old must be removed first.
Common questions in Cliffe
I let a flat near Higham station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or email us with the details for a clear quote.
Is Cliffe within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
What is a movement joint?
It’s a deliberate gap that lets the wall expand and contract without cracking. It should be filled with flexible sealant, never mortar.
Why do you put foam in the joint first?
The foam is closed-cell backing rod. It stops the sealant going in too deep and bonding to three sides so it can flex with the joint.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that usually means someone at home.
How long does external mastic last?
It varies with how exposed the wall is and how much the joint moves. Look for splits, hardening or edges coming away, and reseal at that point.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.

What else we do in Cliffe
Leave it or put it right?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. Around Cliffe, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not guesswork. That is why we ask about the job first and agree the price before starting.

The process
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes a few hours for a handful of joints, longer for a whole elevation. In a small place like Cliffe, 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
- For business premises, tell us about site rules or sign-in
- Let us know about stairs, lifts or work at height
- Tell us about any previous sealing or DIY attempts

Cliffe buildings and the weather
Cliffe is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on movement joints and outside wall joints, especially on the side facing the sea. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like St Helen's Church of England Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Homes close to Church of St Helen include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.
