External mastic for World's End homes and businesses

How we handle external mastic in World's End

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, leaving it bonded to two faces so it can move with the wall. We work on joints between brick and frames, render & cladding joints and brickwork movement joints, and the jobs we see most are failed sealant between panels on a façade and failed seals between different materials.

Outbuildings, garages and conservatories around homes in places like World's End add more joints to look after. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.

Each job carries a 12-month guarantee, whatever its size.

World's End buildings and the weather

Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Ockenden Manor (about 3 miles north) are a reminder that the area around World's End has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.

If you look after a building such as Manor Field Primary School, larger buildings have long runs of movement joint that eventually need resealing. Homes close to St Andrew's Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

Why act early in World's End

A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. Around World's End, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.

Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

How it works

We bring everything the job needs with us, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours to a few days, depending on the length of joint and the access. For a job in World's End, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. First we look over the joints with you, agree which to renew and talk through access.
  2. We cut out the failed sealant and rake out any dirt or growth.
  3. Both sides are cleaned back to sound material and primed if needed.
  4. We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
  5. We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.

Before we arrive

  • Mention any sign-in or site rules at work premises
  • Tell us about access, such as stairs, a lift or high-level joints
  • Move anything stored near the joints

Advice

Your questions about external mastic in World's End

Is World's End within the area you cover?

Yes. World's End is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

I let a flat near Wivelsfield station. Can you help?

Yes. We work for letting agents and landlords as well as householders, and several properties can go on one quote. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.

Should I point up the gap in my brickwork?

No, not where the gap is a movement joint. Pointing it stops it working, and the wall may crack nearby. A flexible sealant is the right fill.

Can you seal over the old sealant?

No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.

When is the sealant fully cured?

Cure times vary by product and the temperature. Before we leave, we will tell you the cure time.

Do I need to be at home?

That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.

Where do you work from?

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

Are you ARBOMaster approved?

Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.

When it isn’t the sealant

A few problems are outside what sealant work can do:

  • Loose or hollow render, which needs re-rendering
  • Damp from another source, such as a leaking gutter or a bridged damp-proof course
  • Movement that’s more than a sealant joint can take

If in doubt, call 0345 464 0079 or send us an email and we will say what we think.

What we seal

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

Different surfaces, different methods

Copings and trims

Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.

Cladding and façade panels

Panels heat up and cool down quickly, so the joint sealant has to cope with frequent movement. We choose the product to suit.

Common problems we fix in World's End

Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.

Common reasons people contact us are:

  • Hard, crazed mastic that has stopped moving
  • Weeds or debris growing in open joints
  • Sealant pulling away from one side of the joint
  • Cracked joints where brick meets render or frames

For landlords with property near Wivelsfield station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

How to choose a mastic man

Looking after it afterwards

Good habits help new joints last longer. Our tips:

  • Check external joints each spring
  • Never let anyone fill a movement joint with mortar
  • Avoid pressure-washing directly into sealant joints
  • Ask before painting over external sealant

Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead over time.

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 it’s worth resealing at the first signs.
