External & façade joints in Southfields, Thurrock
Our applicators work in Southfields on sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly.

- Plants rooting in failed movement joints
How we handle external mastic in Southfields
A movement joint is only as good as its depth. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. We work on render & cladding joints, joints between brick and frames and façade panels, and people most often call us about movement joints with cracked, split or missing sealant and panel joints letting water in.
In a village or hamlet like Southfields, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Common questions in Southfields
Is external mastic in a coastal place like Southfields any different?
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 work for landlords with property near Stanford-Le-Hope station?
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 send us an email with the details for a clear quote.
Can I add another job to the visit?
Yes. Just list everything you need and we will quote it together.
Can you seal joints between render and window frames?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. The colour is chosen to suit.
Is it messy?
We keep the work tidy. Nearby surfaces are protected.
Do you cover Southfields?
Yes, we do. Southfields is part of the area we cover, and the service is the same as everywhere else.
Do you have insurance?
Yes. Mr Mastic is fully insured.
Is there a guarantee?
Yes. All our work carries a one-year guarantee.
DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Aftercare tips
Aftercare is simple, and it makes a real difference:
- Do not let climbing plants root in the sealant
- Look over the joints every year, ideally after winter
- Fix overflowing gutters above sealed joints
- Get split or bare joints resealed while the damage is small
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.

What the job involves on each surface
Joints between dissimilar materials
Each side of the joint may need its own preparation. We prepare both faces so the sealant bonds properly.
Render joints
Render is weaker at the surface than brick, so a sealant that stretches easily protects the edges. We prime where the product needs it.
Leave it or put it right?
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. In a small place like Southfields, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

What affects the cost of external mastic
We do not publish a price list. The quote depends on:
- The size of the job
- Any mould that needs treating
- When we can work, for business premises
- The old material and how stubborn it is
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, call 0345 464 0079 or send us an email for an honest opinion and a quote.
Asking for a quote
To help us quote quickly, let us know:
- The type of property
- Access, such as stairs, a lift or height
- Photos by email, if that is easy
- What the problem is, such as mould, gaps, leaks or cracking
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email pictures if that’s easy.
What happens on the day
At the end, we look at the finished work together and tell you how long to leave it. The visit itself normally takes a few hours for a handful of joints, longer for a whole elevation, depending on the amount of work. Somewhere like Southfields needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Mention any tricky access
- Let us know if you’ve seen damp or leaks
- Let us know about parking restrictions

Walls and rooflines in Southfields
Southfields 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. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to St Giles & All Saints Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. Managing a site like Orsett Church of England Primary School? Then larger buildings have long runs of movement joint that eventually need resealing. If you let a flat or house near Stanford-Le-Hope station, outside joints that have cracked can let damp into a rental, so check them between lets.
