DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
About our external mastic in Rew Street
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We take the old material out and do it properly. If you are dealing with panel joints letting water in and joints pointed up with cement by mistake, we can put it right, on joints between brick and frames, brickwork movement joints and render & cladding joints alike.
In a village or hamlet like Rew Street, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
Every job is covered by a 12-month guarantee.

How it works
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on the building. In a small place like Rew Street, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the joints are inspected and the access agreed.
- 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.
- We apply the sealant, tool it and check the whole run.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Let us know if you’ve seen damp or leaks
- Let us know about earlier repairs to the joints

Advice
What affects the quote in Rew Street
We quote each job individually. This is what makes a difference:
- Mould in or behind the old joints
- How much old sealant there is and how hard it is to remove
- The size of the job
- Any working-time requirements on site
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.
Asking for a quote
Photos help, but a description is a good start. Please mention:
- The type of property
- A few pictures by email, if you can
- What the problem is, such as mould, gaps, leaks or cracking
- Where the property is
Getting a quote is simple: let us know the job and the location and its rough size. A few photos by email make the job easier to understand, and we will come back to you with a quote.
How to look after the new joints
A little care helps the new joints last. We recommend:
- Leave the joints unpainted unless we’ve said otherwise
- Tell anyone working on the walls about the movement joints
- Fix overflowing gutters above sealed joints
- Keep movement joints as flexible joints, not mortar
Don’t paint over the new sealant unless we’ve said the product is paintable. Paint can crack on a flexible joint and spoil the finish.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
Different surfaces, different methods
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.
Copings and trims
Coping and trim joints face rain and sun head on. We reseal them with an exterior sealant suited to the material.
Outside joints around Rew Street
Rew Street is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around All Saints' Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Signs you need external mastic in Rew Street
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
These are the problems we’re asked about most:
- Sealant that has lost its bond to the brick or render
- Water getting into walls through failed joints
- Failed seals between different materials
- Weathered mastic that no longer stretches
If you look after a building such as Northwood Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Why deal with it now?
A failed movement joint lets water into the wall and can run behind render or cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. Around Rew Street, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Common questions in Rew Street
Does the coastal weather in Rew Street affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.
Is Rew Street in your area for external mastic?
Yes, Rew Street is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing, and we will give you a clear quote.
I rent my home. Can I book you?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Do you have insurance?
Yes. Full insurance covers our work.
Can new sealant go over the old?
No. We remove every bit of old sealant first.
Is it messy?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
How often do external joints need resealing?
That varies with the weather the wall faces, how much it moves and the sealant used. Treat it as a maintenance item and look at it yearly and renew it when it starts to fail.
