The process
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the work takes a few hours to a few days, depending on the length of joint and the access in most cases. Somewhere like Frinsted needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive

Advice
External mastic for homes and businesses in Frinsted
Movement joints let brickwork, render and cladding expand and shrink without cracking. 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. If you’re dealing with hard, crazed mastic that has stopped moving and cracked joints where brick meets render or frames, we can put it right, whatever the surface.
In a village or hamlet like Frinsted, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

What the job involves on each surface
Render joints
Water behind render can lead to blown patches. Resealing the joints early keeps water out and helps it last.
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. The old joint is removed and a sealant that bonds to both sides goes in.
Outside joints around Frinsted
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Leeds Castle (about 4 miles south-west) are a reminder that the area around Frinsted has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Letting a property close to Harrietsham station? Then split movement joints are easy to miss on a rental until damp shows inside. In the older streets around St Giles, older walls, gutters and the joints where extensions meet them need a flexible sealant.

What’s near Frinsted
Around Frinsted, our work takes us to homes and buildings near The Blacksmith's Arms Public House and the streets around them.

Why deal with it now?
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost, so the damage spreads beyond the joint. Around Frinsted, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.

Do you need external mastic in Frinsted?
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and rips as the joint opens.
The most common problems we see are:
- Old sealant gone brittle and cracked
- Joints pointed up with cement by mistake
- Sealant pulling away from one side of the joint
- Failed seals between different materials
If you look after a building such as Milstead and Frinsted Church of England Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Before booking anyone
- When the joint can take water or movement
- Whether VAT is included
- Who turns up on the day
- Which sealant they’ll use, and why
How to look after the new joints
To keep the joints looking good and working properly:
- Get split or bare joints resealed while the damage is small
- Keep high-pressure jets off the joints
- Look over the joints every year, ideally after winter
- Tell anyone working on the walls about the movement joints
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
FAQs for Frinsted
Do you cover Frinsted for external mastic?
Yes. Our work covers London and the South East, and Frinsted is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Do you work for landlords with property near Harrietsham station?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
How do you reach high-level joints?
It depends on the building. Where joints can be reached safely, we will do them. Tell us about the building and we’ll confirm what access is needed.
What is backing rod for?
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.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
What’s an expansion joint in brickwork?
It’s a deliberate gap that lets the wall expand and contract without cracking. It should be filled with flexible sealant, never mortar.
Can you quote for more than one area?
Yes. Just list everything you need and we’ll quote it together.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
