Different surfaces, different methods

Cladding and façade panels

Panels heat up and cool down quickly, so the joints work hard every day. The sealant is chosen with that in mind.

Render joints

Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.

About our external mastic in Frithend

A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, and when it fails, the wall takes the strain and water finds a way in. If you have cracked joints where brick meets render or frames and water getting into walls through failed joints, we can put it right, whatever the surface.

Around Frithend, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water normally gets in.

Your job is guaranteed for a year, as with all our work.

Looking after it afterwards

How long the joints last depends on use and care. We suggest:

  • Tell anyone working on the walls about the movement joints
  • Have failed joints looked at early
  • Ask before painting over external sealant
  • Fix overflowing gutters above sealed joints

Do not let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.

Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick which cost more to put right than the joint.

Common problems we fix in Frithend

Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.

Signs it’s time to call us include:

  • Movement joints with cracked, split or missing sealant
  • Movement joints filled with mortar instead of sealant
  • Gaps where render, brick and frames meet
  • Joints where the bead has come unstuck

If you live in an older home near The Church Of The Good Shepherd, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Questions from Frithend

Can you help a landlord with a rental near Bentley (Hampshire) station?

Yes, we work for landlords and agents. Just call 0345 464 0079 or email us and tell us about the property, and we’ll send you a clear quote.

Is Frithend within the area you cover?

Yes. Frithend is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Do you remove the old sealant?

Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.

Where do you work from?

Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.

What is a movement joint?

A vertical gap in a long brick wall is usually a movement joint. It gives the wall room to move.

How much does external mastic cost in Frithend?

There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.

Is there a guarantee?

Yes: twelve months. If there’s a problem with our work in that time, tell us and we will put it right.

How often do external joints need resealing?

There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. Check them each year and reseal when they split or harden. Our work comes with a 12-month guarantee.

What we do, step by step

Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from a few hours to several days, depending on the building. Somewhere as small as Frithend, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. First, the joints are inspected and the access agreed.
  2. Every bit of old sealant and any mortar or debris is cut out.
  3. The faces are brushed clean and primed where the product requires it.
  4. Backing rod sized to the joint goes in to set the depth.
  5. We apply the sealant, tool it and check the whole run.

How to prepare

  • Keep pets and children clear of the area while we work
  • Tell us about any previous sealing or DIY attempts
  • Let us know about parking restrictions

In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.

Why it’s worth doing now in Frithend

A failed movement joint lets water into the wall. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. Around Frithend, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

The cost reflects the work involved, not guesswork. That is why we ask a few questions first and give you a clear price before we start.
