About our external mastic in Bradwell Wick

Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. We work on concrete & block, façade panels and joints between brick and frames, and people most often call us about sealant that has lost its bond to the brick or render and rigid filler in a joint that should flex.

External sealant needs dry, clean surfaces, so work around Bradwell Wick is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.

You get a one-year guarantee, the same in Bradwell Wick as everywhere else we work.

How it works

You do not need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the work takes a few hours to a few days, depending on the length of joint and the access for a typical job. Somewhere like Bradwell Wick needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. We start by checking each joint, agreeing the ones to redo and how we will reach them.
  2. The old mastic and anything lodged in the joint is removed.
  3. Both sides are cleaned back to sound material and primed if needed.
  4. Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
  5. A flexible exterior sealant is applied and tooled in a colour to suit the wall.

Preparing for the visit

  • Mention if the joints have been sealed before
  • Keep pets and children clear of the area while we work
  • For indoor joints, keep the area dry beforehand if you can

Why deal with it now?

Sealing over the top of old mastic doesn’t hold for long. New sealant doesn’t bond well to old, weathered sealant, so the old joint is cut out fully first. Where a wall is exposed, as many are in small places like Bradwell Wick, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

What you pay reflects the work, not a rough estimate. That is why we ask about the job first and agree the price before starting.

Why us?

  • Neat joints and a tidy finish
  • Homes, businesses and hotels
  • Quality sealants from Arbo and Everbuild
  • Old sealant always removed completely

Honest limits

It helps to know what we cannot do too:

  • Walls that need new movement joints cut into them
  • Render that’s blown, hollow or coming away
  • Cracking across the wall rather than at a joint

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

Joints and surfaces we work on

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

What we’re called out for in Bradwell Wick

UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.

People normally contact us after spotting one of these:

  • Damp patches traced to an open external joint
  • Hard, crazed mastic that has stopped moving
  • Sealant pulling away from one side of the joint
  • Plants rooting in failed movement joints

For an older house near a landmark such as Church of St Lawrence, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Our hiring checklist

Should I try it myself first?

A DIY attempt does not rule out a professional job. We remove it and do the joint properly.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

Common questions in Bradwell Wick

Do you work for landlords with property near Southminster station?

Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.

Will you come out to Bradwell Wick?

Yes. Bradwell Wick is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

How long does external mastic take?

As a guide, most jobs take a few hours for a handful of joints, longer for a whole elevation. Larger jobs naturally take longer, and we’ll tell you how long to expect.

Where do you work from?

Our base is Crawley. Our area covers South East England, London and Scotland.

Can you reach joints on upper floors?

It depends on the height and the site. Low-level joints are straightforward; for higher ones, send details and we’ll confirm the access.

Do you remove the old sealant?

Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

Do you seal joints where cladding meets other materials?

Yes. Joints between dissimilar materials are a big part of external work. The sealant is chosen to bond to both sides, primed where needed.

Can you work on commercial sites?

Yes. We’ve worked for hotels, offices and other businesses.

Aftercare tips

Good habits help new joints last longer. Our tips:

  • Tell anyone working on the walls about the movement joints
  • Keep soil, plants and ivy away from the joints
  • Walk round the building once a year and look at the joints
  • Keep movement joints as flexible joints, not mortar

Do not paint over the new sealant unless we have said the product is paintable. Many exterior sealants aren’t designed to be painted, and paint can crack as the joint moves.

Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.

What the job involves on each surface

Brickwork movement joints

Brick walls have vertical movement joints to absorb expansion. They’re resealed over backing rod with a low-modulus sealant in a colour to suit the brick.

Joints between dissimilar materials

Brick against render, concrete against metal, stone against timber: every change of material is a joint. A flexible sealant bridges the two so the movement is taken up.

External mastic in Bradwell Wick: local notes

Bradwell Wick is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. 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.

Letting a property close to Southminster station? Then outside joints that have cracked can let damp into a rental, so check them between lets.
