External mastic for Sinkhurst Green homes and businesses

DIY sealant or a professional job?

If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.

Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

About our external mastic in Sinkhurst Green

For buildings in Sinkhurst Green, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. We work on brickwork movement joints, joints between brick and frames and façade panels, and the jobs we see most are rain getting behind render or cladding at a joint and leaking joints around cladding and façade panels.

Around Sinkhurst Green, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.

Each job carries a 12-month guarantee.

Keeping the joints in good condition

How long the joints last depends on use and care. Here’s what we suggest:

  • Get split or bare joints resealed while the damage is small
  • Do not let climbing plants root in the sealant
  • Keep high-pressure jets off the joints
  • Point out the joints to other trades

Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.

Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years.

Landlord and commercial work in Sinkhurst Green

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.

Landlords and letting agents in Sinkhurst Green can book us as well as householders. Sealant work between tenants keeps a property looking cared for.

Is Sinkhurst Green in your area for external mastic?

What external mastic looks like in Sinkhurst Green

Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

For an older house near a landmark such as Church of St Mary, older walls, gutters and the joints where extensions meet them need a flexible sealant. Managing a site like Frittenden Church of England Primary School? Then its movement joints, gutters and trims need looking after like any other building’s. For landlords with property near Headcorn station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Why deal with it now?

Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. In a small place like Sinkhurst Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, ring 0345 464 0079 or email us and we’ll give you an honest view and a quote.

  • What’s wrong with the joints now

What the job involves on each surface

Copings and trims

Joints in copings, parapets and trims are exposed to the worst of the weather. Each is resealed with a weatherproof, flexible sealant.

Render joints

Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. We prime where the product needs it.

How it works

Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours to a few days, depending on the length of joint and the access. In a small place like Sinkhurst Green, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We inspect the joints and agree which need resealing and how they’ll be reached.
  2. Old sealant and any debris are cut and raked out.
  3. The joint faces are cleaned and primed where the sealant needs 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.

How to prepare

  • Mention any sign-in or site rules at work premises
  • Tell us if parking is tricky
  • Keep children and pets away from the work area
