Little Laver External Mastic
Sealing brickwork movement joints, render, cladding and façade joints for householders, landlords and businesses in Little Laver. Fully insured, ARBOMaster approved and guaranteed for a year.
- Failed sealant between panels on a façade

- Cracked joints where brick meets render or frames
External mastic for homes and businesses in Little Laver
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 mortar or filler would crack. If you have old sealant gone brittle and cracked and failed seals between different materials, we can put it right, on copings & trims, concrete & block and joints between brick and frames alike.
Around Little Laver, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
We stand behind the work with a 12-month guarantee, so you are covered after we have gone.

Your questions about external mastic in Little Laver
Do you cover smaller places like Little Laver?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is there a guarantee on external mastic in Little Laver?
All our work, in Little Laver and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
How do I get a quote for external mastic in Little Laver?
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.
What colours does the sealant come in?
The sealant colour is picked to suit the wall. Exterior sealants come in a good range of colours.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Do you work for letting agents?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels in Little Laver.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
How long should I leave it?
That depends on the sealant used, so follow the cure time we give you.
How it works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes a few hours for a handful of joints, longer for a whole elevation, including the tidy-up. For a village or hamlet like Little Laver, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- Both sides are cleaned back to sound material and primed if needed.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- Clear items away from the joints we are working on
- Let us know about stairs, lifts or work at height
- Tell us if parking is tricky

Signs you need external mastic in Little Laver
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.
The most common problems we see are:
- Movement joints filled with mortar instead of sealant
- Sealant pulling away from one side of the joint
- Gaps where render, brick and frames meet
- Movement joints with cracked, split or missing sealant
In and around Little Laver, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.
What your quote should include
- What guarantee comes with the work
- Whether you can choose the colour
- What insurance they hold
- Whether the sealant suits the joint
How we quote for external mastic
The quote reflects the job in front of us. We take into account:
- Any working-time requirements on site
- The number of rooms or windows
- Which sealant suits the joint
- Any mould that needs treating
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
What to tell us for a quote
Before you ask for a quote, have a think about:
- Roughly how big the job is
- Whether it’s a home or a business
- Any previous sealing or DIY work
- Where the property is
Need a quote? Please call 0345 464 0079 or send us an email with a few details. We’ll explain what we’d do and give you a clear price before any work starts.
When something else is needed
In fairness, some problems need a different trade:
- Walls that need new movement joints cut into them
- Rising or penetrating damp from elsewhere in the wall
- Movement that’s more than a sealant joint can take
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly before you book.
What we seal
- Copings & trims

Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
What happens if it’s left?
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and does not last so it’s worth doing right. Older cottages and farmhouses around Little Laver can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not guesswork. That is why we ask about the job first and agree the price before starting.
Why book with us
- Quality sealants from Arbo and Everbuild
- We agree the colour with you first
- Homes, businesses and hotels
- Anti-fungal sanitary silicone in wet areas
Little Laver buildings and the weather
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near Church of St Mary, older walls, gutters and the joints where extensions meet them need a flexible sealant.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
