External mastic in Buckinghamshire: how it works

Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two where mortar or filler would crack. We work on brickwork movement joints, concrete & block and joints between brick and frames, and people most often call us about joints pointed up with cement by mistake and sealant pulling away from one side of the joint.

Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a handful of joints, longer for a whole elevation.

We start by walking round the building and agreeing the joints and the access.
We cut out the old mastic and rake out anything in the joint.
The faces are brushed clean and primed where the product requires it.
Backing rod sized to the joint goes in to set the depth.
We apply the sealant, tool it and check the whole run.

Pricing in Buckinghamshire

What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start.

Around Aylesbury

Around Aylesbury, our work takes us to homes and buildings near Buckinghamshire UTC, Stocklake Park Community School and The Derby Arms Public House and the streets around them. Nearby too are Bearbrook Combined School (0.5 miles west) and Church of St Mary (under half a mile north). Aylesbury has its own railway station: Aylesbury station. Well-known places in the area include Roald Dahl Children's Gallery (within half a mile east) and Royal Buckinghamshire Hospital (within half a mile north). Green spaces nearby include Coombe Hill.

Outside joints across Buckinghamshire

From Aylesbury, High Wycombe and Chesham to its smaller places, buildings across Buckinghamshire have walls, gutters and rooflines of every age. Each needs a sealant that can move, laid at the right depth.

From Victorian terraces to post-war new towns and modern estates, homes across the South East and London cover every era. Each needs the right sealant for its age and materials, wherever it is in Buckinghamshire.

Aylesbury: For an older house near a landmark such as Church of St Mary, an extension built onto an older house moves differently, and the joint between them takes the strain. Rented homes near Aylesbury station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Honest limits

To be straight with you, some problems need a different trade:

Movement that is more than a sealant joint can take
Failed render or damaged cladding panels
Cracked brickwork or render that needs a builder or plasterer

Different surfaces, different methods

Joints between dissimilar materials

Wherever two materials meet, they move differently. A flexible sealant bridges the two.

Cladding and façade panels

Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.

What affects the cost of external mastic

Some jobs are bigger than they look, and some smaller. The main factors:

Whether there’s mould to deal with
Whether the work is at height
When we can work, for business premises
The old material and how stubborn it is

The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and send you a clear quote before work begins.

What to tell us for a quote

Photos help, but a description is a good start. Try to tell us:

What’s wrong with the joints now
If it’s domestic, commercial or a hotel
Any previous sealing or DIY work
Roughly how big the job is

To get a quote, phone 0345 464 0079 or send us an email with the location and a short description of the problem. You’ll have a clear quote before any work starts.

Why deal with it now?

A low-modulus sealant is chosen because it moves without pulling hard at the 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.

Aftercare tips

Aftercare is simple:

Point out the joints to other trades
Have failed joints looked at early
Look over the joints every year, ideally after winter
Fix overflowing gutters above sealed joints

Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.

An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.

Common questions in Buckinghamshire

What colours does the sealant come in?

We aim for a joint that suits the wall rather than one that jumps out. We will talk through colour options before we start.

Do you cover Buckinghamshire?

We do. Our applicators work in Buckinghamshire.

Do I need to be at home?

If the work is inside, we need someone to let us in. After that, you can carry on with your day.

Can tenants book the work?

Of course. Ask your landlord first, and we can send them the quote if that helps.

Do you work at height?

It depends on the height and the site. Ground-floor joints are simple; for higher ones, send details and we’ll confirm the access.

Where are you based?

We’re based in Crawley, and we cover South East England, London and all of Scotland.

Can I do it myself?

Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
