About our external mastic in Shalfleet
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we will confirm what access is needed. If you have panel joints letting water in and plants rooting in failed movement joints, we can help, on brickwork movement joints, joints between brick and frames and copings & trims alike.
In a village or hamlet like Shalfleet, older cottages and farm buildings often stand in the open, 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 there’s a problem with our work within the year, let us know and we will sort it.

How we quote for external mastic
We quote each job individually. These are the things that affect it:
- Working hours on commercial sites
- Whether there’s mould to deal with
- The product the joint needs
- The number of rooms or windows
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What we need to know
When you contact us, it’s useful to know:
- If it’s domestic, commercial or a hotel
- What the problem is, such as mould, gaps, leaks or cracking
- Any access issues, like height or stairs
- Whether it has been sealed before
If you’re in Shalfleet and need external mastic, phone 0345 464 0079 or send us an email. Tell us what the problem is and where, and you’ll get a clear quote before we start.
Walls and rooflines in Shalfleet
Shalfleet is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on movement joints and outside wall joints, especially on the side facing the sea. 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.
Schools such as Shalfleet Church of England Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

How the visit 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 from start to finish. For a village or hamlet like Shalfleet, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Mention any leaks or damp you’ve noticed
- Clear items away from the joints we’re working on

Advice
Landlords, agents and businesses in Shalfleet
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Different surfaces, different methods
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. Their movement joints are sealed over backing rod with a flexible sealant.
Why deal with it now?
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner, so it pays to do it properly once. In a small place like Shalfleet, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Doing several joints on one visit usually makes better use of the time than several visits. You’ll get one clear quote for the whole job.

Common questions in Shalfleet
Will you come out to Shalfleet?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is external mastic in a coastal place like Shalfleet any different?
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.
I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Can you seal joints between two different materials?
Yes. Where different materials meet is one of the most common joints we seal. We use a flexible sealant suited to both surfaces with primer where required.
Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that usually means someone at home.
Is there a guarantee?
Yes. There’s a 12-month guarantee on every job.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Can you quote for more than one area?
Yes. Just list everything you need.
What we are called out for in Shalfleet
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
Look out for any of the following:
- Sealant pulling away from one side of the joint
- Joints with sealant missing in places
- Rain getting behind render or cladding at a joint
- Failed seals between different materials
In the older streets around Church of St. Michael the Archangel, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
