Why act early in Tonge

Water gets in through a failed movement joint and can run behind render or cladding. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. Around Tonge, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

External mastic in Tonge

Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant. Common call-outs are for movement joints with cracked, split or missing sealant and old sealant gone brittle and cracked, across brickwork movement joints, concrete & block and copings & trims.

Older homes in small places like Tonge may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water usually gets in.

Whatever the size of the job, you get the same one-year guarantee in Tonge and across Kent.

What external mastic looks like in Tonge

Tonge is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on movement joints and outside wall joints, especially on the side facing the sea. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Schools such as Sittingbourne Community College are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. If you let a flat or house near Teynham station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. In the older streets around Church of St Giles, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Tonge is about 2 miles east of Sittingbourne, in Kent. Anywhere in ME9, we can carry out external mastic at your property. Tonge is one of 922 towns and villages in Kent we cover for external mastic. For nearby work, see our Chelmsford page, about 30 miles away.

Keeping the joints in good condition

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

  • Keep high-pressure jets off the joints
  • Leave the joints unpainted unless we have said otherwise
  • Never let anyone fill a movement joint with mortar
  • Clear growth from the base of walls and joints

If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.

An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage.

How it works

There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes a few hours for a handful of joints, longer for a whole elevation in most cases. Somewhere as small as Tonge, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  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. We clean both faces of the joint and prime them where the product calls for it.
  4. Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
  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
  • For indoor joints, keep the area dry beforehand if you can
  • Clear the area around the work

Advice

Questions from Tonge

Can you help a landlord with a rental near Teynham station?

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

Is external mastic in a coastal place like Tonge any different?

Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.

Do you do commercial work?

Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.

Can I do it myself?

It depends on the job. High-level, external movement and fire-rated joints are professional jobs.

Which products do you use?

Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will explain our choice.

Do you come to Tonge?

Yes. We cover Tonge and the rest of Kent, as part of our work across South East England, London and Scotland. For a quote, ring 0345 464 0079 or send us an email.

Where do you work from?

Our base is Crawley. We work across South East England, London and Scotland.

Do you seal joints where cladding meets other materials?

Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. The colour is chosen to suit.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.

When it is not the sealant

Before you book, it’s worth knowing the limits:

  • Damp from another source, such as a leaking gutter or a bridged damp-proof course
  • Failed render or damaged cladding panels
  • Structural movement, which needs a surveyor or engineer

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

Quotes for external mastic in Tonge

The price is agreed before any work begins. It takes into account:

  • Which sealant suits the joint
  • Any mould that needs treating
  • How easy the joints are to reach
  • Working hours on commercial sites

A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Asking for a quote

You do not need to know the technical terms. It helps if you can tell us:

  • The type of property
  • Any previous sealing or DIY work
  • The rough size of the job
  • How we’d reach the joints

There’s no standard price list. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or email us.

Should I try it myself first?

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
