How we handle external mastic in Englefield Green

A movement joint is only as good as its depth. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. We’re often asked to deal with moss and dirt in joints with no sealant left and joints where the bead has come unstuck, on copings & trims, concrete & block and façade panels.

In and around Englefield Green, 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.

All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What the job involves on each surface

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.

Cladding and façade panels

Where a cladding system has its own specified sealant, we follow it or an approved alternative. Tell us what the building has when you get in touch.

What we’re called out for in Englefield Green

Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.

The problems people normally mention when they call include:

  • Gaps where render, brick and frames meet
  • Brick movement joints where the sealant has split
  • Moss and dirt in joints with no sealant left
  • Failed sealant between panels on a façade

For landlords with property near Egham station, outside joints that have cracked can let damp into a rental, so check them between lets.

  • Whether you can choose the colour
  • What guarantee comes with the work
  • What happens if they find a problem under the old sealant

Choosing a sealant specialist

When something else is needed

To be straight with you, there are a few things sealant won’t fix:

  • Structural movement, which needs a surveyor or engineer
  • Cracks in the bricks or render themselves, away from the joints
  • Failed render or damaged cladding panels

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

Joints and surfaces we work on

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

For landlords and businesses

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.

What happens if it’s left?

The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost around the joint, so the problem grows beyond the joint itself. In an older home around Englefield Green, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.

Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

How to look after the new joints

Aftercare is simple, and it makes a real difference:

  • Ask before painting over external sealant
  • Never let anyone fill a movement joint with mortar
  • Fix overflowing gutters above sealed joints
  • Act on the first splits you see

Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.

If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.

How it works

At the end, we look at the finished work together and explain the cure time. The visit itself usually takes anything from a few hours to several days, depending on the building, depending on the size of the job. For a job in Englefield Green, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. We start by walking round the building and agreeing the joints and the access.
  2. Every bit of old sealant and any mortar or debris is cut out.
  3. Joint faces are cleaned back and primed if the sealant needs it.
  4. Backing rod sized to the joint goes in to set the depth.
  5. The exterior sealant is applied, tooled and checked along its length.

How to prepare

  • Clear items away from the joints we’re working on
  • Tell us about any water getting in
  • Where the joints are inside, avoid wetting them before we arrive

Advice

External mastic in Englefield Green: local notes

Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Frogmore House (about 3.2 miles north) are a reminder that the area around Englefield Green has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.

In the older streets around Church of Our Lady of the Assumption, an extension built onto an older house moves differently, and the joint between them takes the strain. Managing a site like Englefield Green Infant School and Nurseries? Then its movement joints, gutters and trims need looking after like any other building’s.
