About our external mastic in Cooling Street
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, and when it fails, the wall takes the strain and water finds a way in. Typical jobs include movement joints with cracked, split or missing sealant and panel joints letting water in, across joints between brick and frames, brickwork movement joints and render & cladding joints.
Somewhere as small as Cooling Street, homes and farm buildings often face open ground, 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.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Walls and rooflines in Cooling Street
Cooling Street is within about 3 miles of 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. Historic houses like Temple Manor (about 3.9 miles south) are a reminder that the area around Cooling Street 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.
For landlords with property near Higham station, split movement joints are easy to miss on a rental until damp shows inside. If you look after a building such as Cliffe Woods Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

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 problem grows beyond the joint itself. Older cottages and farmhouses around Cooling Street can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What else we do in Cooling Street
What we do, step by step
On the day, we look over the joints with you first. Surfaces next to the work are protected before work begins. The work normally takes a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Cooling Street, the journey is planned in advance: 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 start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height
- Mention any sign-in or site rules at work premises

Do you need external mastic in Cooling Street?
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, so it pulls away from the edges.
Keep an eye out for any of the following:
- Old sealant gone brittle and cracked
- Joints where the bead has come unstuck
- Movement joints with cracked, split or missing sealant
- Leaking joints around cladding and façade panels
Homes close to St James' Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Landlord and commercial work in Cooling Street
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will quote.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
How the job changes by surface
Concrete and blockwork
The face of concrete or block is often dusty, so preparation is key. We prime where the sealant needs it.
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joints work hard every day. We choose the product to suit.
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Cooling Street: your questions answered
I let a flat near Higham station. Can you help?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Does the coastal weather in Cooling Street 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. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you guarantee your work?
Yes, always. There’s a 12-month guarantee on every job, wherever you are.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Do you hold any approvals?
Yes. We are 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 pictures.
Where do you work from?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Why is there a gap in my brick wall?
Brickwork, render and cladding all move a little, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.
What sealant work cannot fix
We’ll always be straight with you, so here’s what new sealant won’t do:
- Cracking across the wall rather than at a joint
- Walls that need new movement joints cut into them
- Movement that’s more than a sealant joint can take
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly.
