Quotes for external mastic in Ridley
Jobs vary more than people expect. The main factors:
- How easy the joints are to reach
- Mould in or behind the old joints
- The old material and how stubborn it is
- How many rooms, windows or areas are involved
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
What we need to know
To make quoting easier, let us know:
- The rough size of the job
- The type of property
- Where the property is
- How we’d reach the joints
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. Whenever you are ready, call 0345 464 0079 or email us.
How we handle external mastic in Ridley
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 joints with sealant missing in places and leaking joints around cladding and façade panels, we can put it right, on joints between brick and frames, copings & trims and concrete & block alike.
External sealant needs dry, clean surfaces, so work around Ridley is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

Why it’s worth doing now in Ridley
Running new sealant over the old bead rarely lasts. The new layer cannot bond properly to old, weathered material, so the old joint is cut out fully first. Where a wall is exposed, as many are in small places like Ridley, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

Ridley: your questions answered
Is Ridley within the area you cover?
Yes, Ridley is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for landlords with property near Meopham station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or email us with the details for a clear quote.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply phone 0345 464 0079 or drop us an email.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
Should I point up the gap in my brickwork?
No. Cement or mortar cannot stretch and the joint fails. Where a joint has been mortared, it can often be raked out and sealed properly.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator.
How long will you be here?
It depends on the size of the job, but as a guide it takes a few hours for a handful of joints, longer for a whole elevation. We’ll tell you when we quote.
What sealant work cannot fix
In fairness, some problems need a different trade:
- Walls that need new movement joints cut into them
- Cracking across the wall rather than at a joint
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If you’re not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer before booking.
Surfaces we seal
- Copings & trims
- Concrete & block
- Façade panels
- Render & cladding joints
- Joints between brick and frames
- Brickwork movement joints
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Look over the joints every year, ideally after winter
- Wash walls gently around the sealant
- Ask before painting over external sealant
- Clear growth from the base of walls and joints
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.
When to call us in Ridley
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
It’s worth asking for a quote if you see:
- Sealant pulling away from one side of the joint
- Old sealant gone brittle and cracked
- Movement joints filled with mortar instead of sealant
- Damp patches traced to an open external joint
If you let a flat or house near Meopham station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
What your quote should include
- What preparation is included
- Whether the sealant suits the joint
- Whether all the old sealant comes out first
- What the cure time is
External mastic in Ridley: local notes
Historic houses like Cobham College (about 4 miles north-east) are a reminder that the area around Ridley has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to Church of Saint Peter include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you look after a building such as Meopham School, larger buildings have long runs of movement joint that eventually need resealing.

The process
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours to a few days, depending on the length of joint and the access. Somewhere like Ridley 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 look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- 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.
Before we arrive
- Mention any tricky access
- Mention any sign-in or site rules at work premises
