External mastic in Burghfield Hill

External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We strip the joint back and start again. If you have leaking joints around cladding and façade panels and joints pointed up with cement by mistake, we can help, on copings & trims, render & cladding joints and façade panels alike.

In and around Burghfield Hill, older properties sit alongside newer ones, each with its own outside joints. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.

We stand behind the work with a one-year guarantee, so you are covered after we’ve gone.

FAQs for Burghfield Hill

Is Burghfield Hill within the area you cover?

Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Can you help a landlord with a rental near Mortimer station?

Yes. We work for landlords and letting agents as well as homeowners. You can call 0345 464 0079 or drop us an email with the details for a clear quote.

Why is there a gap in my brick wall?

Most straight vertical gaps in brickwork are movement joints. It lets the bricks expand without cracking and needs a flexible seal, not mortar.

When will the joints need doing again?

That depends on the wall, the weather and the movement. Look for splits, hardening or edges coming away.

Do you hold any approvals?

Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.

Is there a guarantee?

Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.

Is it OK to fill a movement joint with cement?

No. Cement or mortar can’t stretch. If it has already been filled, we can normally cut it out and reseal it.

Where do you work from?

We are a Crawley-based firm. We work across South East England, London and Scotland.

How to look after the new joints

So the new joints stay in good condition:

  • Check external joints each spring
  • Fix overflowing gutters above sealed joints
  • Act on the first splits you see
  • Leave the joints unpainted unless we’ve said otherwise

Avoid pressure-washing straight into the joints. High-pressure water can lift the edges.

An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick.

Why it’s worth doing now in Burghfield Hill

The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render near the open joint, so the damage spreads beyond the joint. In an older home around Burghfield Hill, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.

There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or send us an email and we’ll talk you through it.

How it works

We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours for a handful of joints, longer for a whole elevation. Parking around Burghfield Hill is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.

  1. Each joint is checked and the colour of the new sealant agreed.
  2. We take out the old sealant until the faces are sound.
  3. Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
  4. Primer is applied wherever the sealant needs it.
  5. We gun in low-modulus sealant and tool it neatly.

Before we arrive

  • Clear items away from the joints we’re working on
  • Mention if the joints have been sealed before
  • On commercial sites, let us know about site rules

Advice

Honest limits

Sealant is not the answer to every problem, and we’d rather say so up front. Sealant won’t put right:

  • Cracked brickwork or render that needs a builder or plasterer
  • Structural movement, which needs a surveyor or engineer
  • Render that’s blown, hollow or coming away

If you’re not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer.

What we seal

  • Brickwork movement joints
  • Façade panels
  • Concrete & block
  • Joints between brick and frames
  • Copings & trims
  • Render & cladding joints

Different surfaces, different methods

Brickwork movement joints

Brick movement joints are often mistaken for a missing mortar line. If that’s happened, we rake it out and reseal it properly.

Cladding and façade panels

Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. We choose the product to suit.

What external mastic looks like in Burghfield Hill

With historic houses such as Stratfield Saye House (about 4.3 miles south-east) nearby, there’s older building stock in the area around Burghfield Hill as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Schools such as Garland Junior School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. Homes close to Church of St Mary include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. Rented homes near Mortimer station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
