How we handle external mastic in Cliftonville
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. We work on render & cladding joints, joints between brick and frames and brickwork movement joints, and people most often call us about joints with sealant missing in places and joints pointed up with cement by mistake.
In and around Cliftonville, older properties sit alongside newer ones, each with its own outside joints. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.
There’s a 12-month guarantee on every job.

FAQs for Cliftonville
Is Cliftonville within the area you cover?
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.
Does living near the coast affect external mastic in Cliftonville?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few photos.
Are you fully insured?
Yes, we are fully insured for every job we do.
Should I point up the gap in my brickwork?
No. Cement or mortar cannot stretch. Where a joint has been mortared, it can often be raked out and sealed properly.
I’m a tenant. Can you help?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Do the sealants smell?
Some sealants have a smell while they cure. Opening a window helps.
How it works
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on the building for a typical job. Parking around Cliftonville is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any previous sealing or DIY attempts
- Where the joints are inside, avoid wetting them before we arrive

Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Cliftonville buildings and the weather
Cliftonville is close to 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. With historic houses such as Quex Park (about 3.9 miles west) nearby, there’s older building stock in the area around Cliftonville as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Managing a site like Cliftonville Primary School? Then its movement joints, gutters and trims need looking after like any other building’s. Homes close to Church of St Paul include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Avoid pressure-washing directly into sealant joints
- Keep movement joints as flexible joints, not mortar
- Point out the joints to other trades
- Check external joints each spring
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
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 so early resealing is worth it.
Why it’s worth doing now in Cliftonville
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. In an older home around Cliftonville, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Common problems we fix in Cliftonville
Every building moves. 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.
These are the problems we are asked about most:
- Water getting into walls through failed joints
- Sealant pulling away from one side of the joint
- Hard, crazed mastic that has stopped moving
- Rigid filler in a joint that should flex
For landlords with property near Margate station, outside joints that have cracked can let damp into a rental, so check them between lets.

What the job involves on each surface
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.
Render joints
Rendered walls have joints at beads, openings and changes of material. They’re resealed in a sealant that suits the render.
