External mastic in Arpinge

For buildings in Arpinge, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. We work on joints between brick and frames, brickwork movement joints and façade panels, and common reasons people get in touch are joints where the bead has come unstuck and rain getting behind render or cladding at a joint.

External sealant needs dry, clean surfaces, so work around Arpinge is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.

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

What we’re called out for in Arpinge

Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.

If you can see any of these, it’s time to have the joints looked at:

  • Failed seals between different materials
  • Hard, crazed mastic that has stopped moving
  • Joints pointed up with cement by mistake
  • Damp patches traced to an open external joint

For an older house near a landmark such as St Oswald's Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Before you book anyone

  • What insurance they hold
  • What guarantee comes with the work
  • When the joint can take water or movement
  • Whether all the old sealant comes out first

Quotes for external mastic in Arpinge

Jobs vary more than people expect. The main factors:

  • Whether old sealant or filler has to be cut out
  • The amount of work
  • How many rooms, windows or areas are involved
  • Any mould that needs treating

Combining jobs into one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.

What to tell us for a quote

Photos by email are helpful but not essential. Try to tell us:

  • Access, such as stairs, a lift or height
  • Whether it’s a home or a business
  • What the problem is, such as mould, gaps, leaks or cracking
  • Photos by email, if that’s easy

Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. Whenever you’re ready, ring 0345 464 0079 or send us an email.

Landlords, agents and businesses in Arpinge

We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll quote.

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.

The process

All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. It normally takes a few hours to a few days, depending on the length of joint and the access. Somewhere like Arpinge needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. We start by walking round the building and agreeing the joints and the access.
  2. We cut out the old mastic and rake out anything in the joint.
  3. The faces are brushed clean and primed where the product requires it.
  4. We fit closed-cell backing rod to control the depth.
  5. The exterior sealant is applied, tooled and checked along its length.

How to prepare

  • Tell us if parking is tricky
  • On commercial sites, let us know about site rules
  • Keep children and pets away from the work area

What we cannot put right

It helps to know what we can’t do too:

  • Cracking across the wall rather than at a joint
  • Render that is blown, hollow or coming away
  • Structural movement, which needs a surveyor or engineer

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

What we seal

  • Façade panels
  • Concrete & block
  • Render & cladding joints
  • Copings & trims

  • Brickwork movement joints

Arpinge questions

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

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.

Do you work for landlords with property near Folkestone West station?

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

Do you guarantee your work?

Yes. All our work carries a 12-month guarantee.

Will you leave a mess?

We keep the work tidy. Nearby surfaces are protected.

Are you fully insured?

Yes. Mr Mastic is fully insured.

Do the sealants smell?

Possibly a little. Any smell clears as the sealant cures, and ventilation helps.

Can you reach joints on upper floors?

Each building is different. Tell us the height, the number of joints and what’s below them, and we will confirm what access is needed.

Can you work on commercial sites?

Yes. Hotels, offices and other businesses use us, and we are fully insured.

External mastic in Arpinge: local notes

Arpinge is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Historic houses like Acrise Place (about 2.1 miles north) are a reminder that the area around Arpinge has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.

For landlords with property near Folkestone West station, outside joints that have cracked can let damp into a rental, so check them between lets. Schools such as Harcourt Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

DIY versus a professional finish

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Leave it or put it right?

Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. Where a wall is exposed, as many are in small places like Arpinge, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.
