Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
How we handle external mastic in Shipton Bellinger
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant. If you are dealing with gaps where render, brick and frames meet and joints where the bead has come unstuck, we can put it right, on render & cladding joints, brickwork movement joints and façade panels alike.
Outside joints can only be sealed when they’re dry, so work in Shipton Bellinger is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

Questions from Shipton Bellinger
Can you help a landlord with a rental near Grateley station?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Is Shipton Bellinger within the area you cover?
Yes, Shipton Bellinger is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
How much does external mastic cost in Shipton Bellinger?
Size, access and the old material all affect the cost. Ask us for a quote and we will talk you through it.
What is a movement joint?
It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.
Do you work for hotels and businesses?
Yes. We can plan bigger jobs in stages to suit the site.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. Indoors, that generally means someone at home.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.

What we do, step by step
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. Once we have agreed what’s being done, we protect the area and start. Most jobs take a few hours for a handful of joints, longer for a whole elevation. In a small place like Shipton Bellinger, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the joints are inspected and the access agreed.
- 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.
How to prepare
- Mention if the joints have been sealed before
- Keep children and pets away from the work area
- Let us know about parking restrictions

Advice
How to look after the new joints
To keep the joints looking good and working properly:
- Ask before painting over external sealant
- Keep soil, plants and ivy away from the joints
- Keep movement joints as flexible joints, not mortar
- Walk round the building once a year and look at the joints
Don’t paint over the new sealant unless we’ve said the product is paintable. Paint can crack on a flexible joint and spoil the finish.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
What we cannot put right
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Subsidence or other structural problems
- Damp that is not coming from the joint
- Cracking across the wall rather than at a joint
If you’re not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer before booking.
Surfaces we seal
- Render & cladding joints
- Joints between brick and frames
- Copings & trims
- Façade panels
- Concrete & block
- Brickwork movement joints
Why it’s worth doing now in Shipton Bellinger
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. Around Shipton Bellinger, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before any work starts.

How the job changes by surface
Joints between dissimilar materials
Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant so the movement is taken up.
Cladding and façade panels
Cladding and façade panels are usually separated by sealed joints. We reseal them with a sealant suited to the panel material.
External mastic in Shipton Bellinger: local notes
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.
Managing a site like Shipton Bellinger Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Homes close to Church of St Peter include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.
