Your questions about external mastic in Great Wakering
Do you cover smaller places like Great Wakering?
Yes. Great Wakering is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Does the coastal weather in Great Wakering affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
How long before the joint can be used?
Different products cure at different speeds, so please follow the time we give you.
What does external mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.
Can tenants book the work?
Yes. Check with your landlord; we can send the quote to them too.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
External mastic in Great Wakering, done properly
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. If you’re dealing with failed seals between different materials and failed sealant between panels on a façade, we can help.
Outbuildings, garages and conservatories around homes in places like Great Wakering add more joints to look after. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Great Wakering buildings and the weather
Great Wakering is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Shoeburyness station, split movement joints are easy to miss on a rental until damp shows inside. In the older streets around Church of St Nicholas, an extension built onto an older house moves differently, and the joint between them takes the strain.

What we cannot put right
In fairness, some problems need a different trade:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Render that is blown, hollow or coming away
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think before booking.
Joints and surfaces we work on
- Concrete & block
- Render & cladding joints
- Copings & trims
- Façade panels
- Brickwork movement joints
- Joints between brick and frames
Signs you need external mastic in Great Wakering
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, and it tears off the sides.
Most people get in touch after spotting something like this:
- Damp patches traced to an open external joint
- Rigid filler in a joint that should flex
- Brick movement joints where the sealant has split
- Sealant pulling away from one side of the joint
If you look after a building such as Great Wakering Primary Academy, larger buildings have long runs of movement joint that eventually need resealing.

Work for landlords, hotels and businesses
Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
We regularly work with letting and managing agents. Tell us the address, the job and how access works.
How the visit 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. For a job in Great Wakering, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any water getting in
- Clear the area around the work
How to get a quote

Different surfaces, different methods
Concrete and blockwork
Big joints in concrete need careful depth control. We size the backing rod to the gap and keep the sealant to the right depth.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant coloured to suit the wall.
Why act early in Great Wakering
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 Great Wakering, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference.
