External Mastic in Ridgeway
Our applicators work in Ridgeway on sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Rigid filler in a joint that should flex
- Joints with sealant missing in places
- Water getting into walls through failed joints
Aftercare tips
How long the joints last depends on use and care. We suggest:
- Clear growth from the base of walls and joints
- Keep water from gutters off the wall
- Never let anyone fill a movement joint with mortar
- Show decorators and builders where the movement joints are
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
Act while the splits are small. Then it’s a straightforward cut-out and reseal.
External mastic in Ridgeway
Movement joints let brickwork, render and cladding expand and shrink without cracking. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. If you’re dealing with joints with sealant missing in places and joints where the bead has come unstuck, we can help.
Outside joints can only be sealed when they’re dry, so work in Ridgeway is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
Big or small, it’s backed by our one-year guarantee in Ridgeway and across Kent.

When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Movement that is more than a sealant joint can take
- Cracking across the wall rather than at a joint
- Render that is blown, hollow or coming away
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly before booking.

What affects the cost of external mastic
Every job gets its own quote. These are the things that affect it:
- How many rooms, windows or areas are involved
- The amount of work
- The old material and how stubborn it is
- Working hours on commercial sites
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Photos by email, if that’s easy
- Any previous sealing or DIY work
- How many joints, rooms or windows are involved
- How we’d reach the joints
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we’ll talk you through the work and give you a clear price.
Should I try it myself 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.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Do you need external mastic in Ridgeway?
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
Any of these means the joints need attention:
- Leaking joints around cladding and façade panels
- Weathered mastic that no longer stretches
- Water getting into walls through failed joints
- Rigid filler in a joint that should flex
If you look after a building such as Smeeth Community Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Before booking anyone
- How much experience the applicator has
- Whether they seal over old material or remove it
- Whether they’re fully insured
- What happens if the job turns out different
What happens if it’s left?
Water gets in through a failed movement joint. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. Where a wall is exposed, as many are in small places like Ridgeway, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Ask us for a quote and we will explain what it covers.

What external mastic looks like in Ridgeway
Historic houses like Westenhanger Castle (about 3.6 miles south-east) are a reminder that the area around Ridgeway 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. 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.
Homes close to Church of St Mary include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. If you let a flat or house near Westenhanger station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

How it works
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Ridgeway, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Tell us if parking is tricky
- Let us know about stairs, lifts or work at height

Advice
Your questions about external mastic in Ridgeway
Do you work for landlords with property near Westenhanger station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
Do you cover smaller places like Ridgeway?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do the sealants smell?
There can be a smell while the sealant cures. Opening a window helps.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you.
How much does external mastic cost in Ridgeway?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we will talk you through it.
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.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Should I point up the gap in my brickwork?
No. Cement or mortar can’t stretch, so the joint stops doing its job. Where a joint has been mortared, it can often be raked out and sealed properly.
