How we handle external mastic in Ufton Nervet
For buildings in Ufton Nervet, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean joint faces and the right depth. If you have water getting into walls through failed joints and sealant that has lost its bond to the brick or render, we can put it right, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Ufton Nervet is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Our work is backed for twelve months.

DIY versus a professional finish
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.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Questions from Ufton Nervet
Do you cover Ufton Nervet for external mastic?
Yes. Our work covers London and the South East, and Ufton Nervet is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
Can you help a landlord with a rental near Aldermaston station?
Yes. We work for landlords and letting agents as well as householders. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Do you seal joints where cladding meets other materials?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides, primed where needed.
Where are you based?
Mr Mastic is based in Crawley. We cover Ufton Nervet and the rest of West Berkshire.
Can you quote for more than one area?
Of course. Doing several areas at once is usually more efficient.
What’s an expansion joint in brickwork?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It should be filled with flexible sealant, never mortar.
Can you match the colour of my brickwork?
The aim is a neat, even joint in a colour that suits the wall. Colour is agreed with you before we begin, matched as closely as the range allows.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
What the job involves on each surface
Joints between dissimilar materials
Wherever two materials meet, they move differently. A flexible sealant bridges the two.
Copings and trims
Coping joints that leak let water straight down into the wall. Sealing them early saves the wall below.
What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours to a few days, depending on the length of joint and the access and we leave things clean and tidy. For a village or hamlet like Ufton Nervet, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Let us know about earlier repairs to the joints
- Mention any sign-in or site rules at work premises
- Clear items away from the joints we are working on

What affects the quote in Ufton Nervet
Every job gets its own quote. These are the things that affect it:
- Any mould that needs treating
- The old material and how stubborn it is
- Any working-time requirements on site
- How much there is to do
Some things make a job bigger or smaller: 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 we need to know
When you call or email, it’s useful to know:
- If someone has resealed it before
- How many joints, rooms or windows are involved
- Photos by email, if that’s easy
- How we’d reach the joints
To get a quote, phone 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. You’ll have a clear quote before any work starts.
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Tell anyone working on the walls about the movement joints
- Wash walls gently around the sealant
- Have failed joints looked at early
- Never let anyone fill a movement joint with mortar
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
What external mastic looks like in Ufton Nervet
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as Sulhamstead and Ufton Nervet School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you let a flat or house near Aldermaston station, split movement joints are easy to miss on a rental until damp shows inside. In the older streets around Church of St Peter, older walls, gutters and the joints where extensions meet them need a flexible sealant.
