What we are called out for in Kirby Cross

Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.

The most common problems we see are:

  • Weeds or debris growing in open joints
  • Movement joints with cracked, split or missing sealant
  • Sealant pulling away from one side of the joint
  • Gaps where render, brick and frames meet

If you let a flat or house near Frinton-On-Sea station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Questions to ask before booking

  • Whether all the old sealant comes out first
  • Whether VAT is included
  • Who turns up on the day
  • Whether the sealant suits the joint

Our hiring checklist

External mastic in Kirby Cross

Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where mortar or filler would crack. We’re often asked to deal with joints pointed up with cement by mistake and plants rooting in failed movement joints, on concrete & block, copings & trims and render & cladding joints.

In a smaller place like Kirby Cross, some homes face open ground, so exposed walls and rooflines take more wind-driven rain. That is where gutter joints and wall joints tend to fail first.

You’re covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or drop us an email.

When it is not the sealant

Some problems need a builder, plumber or other trade rather than us:

  • Loose or hollow render, which needs re-rendering
  • Cracking across the wall rather than at a joint
  • Structural movement, which needs a surveyor or engineer

Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.

Joints and surfaces we work on

How the visit works

The work is kept neat and contained to the area we are working on, so you can get on with your day. Expect the work to take a few hours for a handful of joints, longer for a whole elevation, and we explain the cure time before we leave. For a job in Kirby Cross, 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. We inspect the joints and agree which need resealing and how they’ll be reached.
  2. The old mastic and anything lodged in the joint is removed.
  3. We clean both faces of the joint and prime them where the product calls for it.
  4. Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
  5. The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.

Getting ready for the visit

  • Let us know about parking restrictions
  • Tell us about any water getting in
  • On commercial sites, let us know about site rules

Can I do it myself?

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

Your questions about external mastic in Kirby Cross

Can you help a landlord with a rental near Frinton-On-Sea station?

Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.

Does the coastal weather in Kirby Cross affect outside sealant?

Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.

Can you seal over the old sealant?

No. We remove every bit of old sealant first.

Will the new joint stand out?

The aim is a neat, even joint in a colour that suits the wall. We’ll talk through colour options before work begins from the range available.

What does external mastic cost?

We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before we start.

Is it worth trying it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Do you come to Kirby Cross?

Yes, we do. Kirby Cross is part of the area we cover.

How long will you be here?

Typically it takes a few hours for a handful of joints, longer for a whole elevation. Larger jobs naturally take longer, and we will say how long yours will take.

Cladding and façade panels

Where a cladding system has its own specified sealant, we follow it. Send us any details you have about the façade.

Joints between dissimilar materials

Each side of the joint may need its own preparation. We prepare both faces so the sealant bonds properly.

Aftercare tips

Once the sealant has cured, a few habits help it last:

  • Keep movement joints as flexible joints, not mortar
  • Clear growth from the base of walls and joints
  • Show decorators and builders where the movement joints are
  • Ask before painting over external sealant

Only paint over the joint if we’ve confirmed the sealant can take paint. Many exterior sealants are not designed to be painted.

Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.

Landlord and commercial work in Kirby Cross

Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we’ll give you a quote.

Walls and rooflines in Kirby Cross

Kirby Cross is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. 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.

Schools such as Frinton-on-Sea Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. For an older house near a landmark such as St Mary Magdalene, the joints between older walls, newer extensions and the roofline need a sealant that can move.
