About our external mastic in Nutbourne
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. We pick a colour that sits well with the wall so the line blends in. Common call-outs are for sealant that has lost its bond to the brick or render and gaps where render, brick and frames meet, on render & cladding joints, brickwork movement joints and concrete & block.
Somewhere as small as Nutbourne, 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 stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

What we are called out for in Nutbourne
Some movement joints have been pointed up with mortar. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
If you can see any of these, it’s time to have the joints looked at:
- Sealant pulling away from one side of the joint
- Movement joints filled with mortar instead of sealant
- Leaking joints around cladding and façade panels
- Weathered mastic that no longer stretches
Homes close to St Wilfrid's Church and Hall include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

What external mastic looks like in Nutbourne
Nutbourne 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’s 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Schools such as Chidham Parochial Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Rented homes near Nutbourne station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

How the job changes by surface
Render joints
Rendered walls have joints at beads, openings and changes of material. We reseal them with a flexible exterior sealant that suits the render colour.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. Where one has been mortared, we cut it out and reseal it with sealant where it can be done safely.
What affects the quote in Nutbourne
The price is agreed before any work begins. It’s based on:
- How easy the joints are to reach
- Working hours on commercial sites
- How much old sealant there is and how hard it is to remove
- The number of rooms or windows
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.
What we need to know
Photos by email are helpful but not essential. Please mention:
- Any previous sealing or DIY work
- Pictures of the joints, sent by email
- If it’s domestic, commercial or a hotel
- Any access issues, like height or stairs
We quote each job on its own, so start by telling us what you need. Just call 0345 464 0079 or send us an email with the details.
What happens on the day
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a handful of joints, longer for a whole elevation. Somewhere as small as Nutbourne, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Let us know about earlier repairs to the joints
- Let us know if you’ve seen damp or leaks
- Clear the area around the work

Advice
FAQs for Nutbourne
Can you help a landlord with a rental near Nutbourne station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Will you come out to Nutbourne?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you seal joints where cladding meets other materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. We pick a colour that works with both materials.
Should I point up the gap in my brickwork?
No, not if it’s a movement joint. Pointing it stops it working and can lead to cracking. A flexible sealant is the right fill.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll explain our choice.
Do you have insurance?
Yes. Mr Mastic is fully insured.
What does external mastic cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before we start.
How often do external joints need resealing?
It varies from wall to wall: sunny, exposed elevations and busy joints wear faster. A yearly look will tell you when they need doing. Our work comes with a 12-month guarantee.
For landlords and businesses
If you manage several properties in or around Nutbourne, jobs at different addresses can be quoted together. Send us the addresses and the work at each.
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Look over the joints every year, ideally after winter
- Avoid pressure-washing directly into sealant joints
- Deal with leaking gutters that soak the joints below
- Don’t let climbing plants root in the sealant
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
