About our external mastic in Etchinghill

Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. We pick a colour that sits well with the wall so the line blends in. We work on concrete & block, façade panels and render & cladding joints, and common reasons people get in touch are weathered mastic that no longer stretches and moss and dirt in joints with no sealant left.

Older homes in small places like Etchinghill may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water usually gets in, and they need the right sealant at the right depth.

A one-year guarantee comes as standard.

The process

There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes anything from a few hours to several days, depending on the building, including the tidy-up. In a small place like Etchinghill, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. Each joint is checked and the colour of the new sealant agreed.
  2. Failed sealant is removed back to clean, sound faces.
  3. Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
  4. Primer is applied wherever the sealant needs it.
  5. A low-modulus exterior sealant is gunned in and tooled to a neat finish.

Getting ready for the visit

Looking after it afterwards

No joint lasts for ever, but care makes a real difference. A few tips:

  • Never let anyone fill a movement joint with mortar
  • Do not let climbing plants root in the sealant
  • Check external joints each spring
  • Deal with leaking gutters that soak the joints below

Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead and let water in behind.

Act while the splits are small. Then it’s a straightforward cut-out and reseal before water has had years to get in.

What sealant work cannot fix

Honest advice matters more to us than a booking, so here’s what sealant cannot fix:

  • Rising or penetrating damp from elsewhere in the wall
  • Adding movement joints to masonry that has none
  • Failed render or damaged cladding panels

If you’re not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.

What we seal

  • Render & cladding joints
  • Joints between brick and frames
  • Copings & trims
  • Brickwork movement joints
  • Façade panels
  • Concrete & block

Work for landlords, hotels and businesses

Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.

Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we’re fully insured for the work.

Should I try it myself first?

The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.

What affects the quote in Etchinghill

There’s no set price list. The quote depends on:

  • Whether old sealant or filler has to be cut out
  • How easy the joints are to reach
  • The number of rooms or windows
  • Any mould that needs treating

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will explain what it covers.

Helping us quote

Before you ask for a quote, have a think about:

  • Where the property is
  • If it’s domestic, commercial or a hotel
  • Any access issues, like height or stairs
  • Photos by email, if that’s easy

When to call us in Etchinghill

UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.

Any of these means the joints need attention:

  • Hard, crazed mastic that has stopped moving
  • Gaps where render, brick and frames meet
  • Weeds or debris growing in open joints
  • Movement joints with cracked, split or missing sealant

For landlords with property near Sandling station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Questions to ask before booking

  • How the colour is chosen
  • What happens if they find a problem under the old sealant
  • What the quote includes, VAT included or not
  • What insurance they hold

10 questions to ask before you book

What external mastic looks like in Etchinghill

Etchinghill is within about 3 miles of 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. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Schools such as Lyminge Church of England Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Historic houses such as Acrise Place, about 2.4 miles north-east, show how far back building around Etchinghill goes, and older homes nearby need a sealant that suits their walls.

Questions from Etchinghill

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

Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or send us an email with the details for a clear quote.

Does living near the coast affect external mastic in Etchinghill?

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.

Will the new joint stand out?

There’s a good range of exterior colours, including greys, browns, whites and stone tones. We pick the one that suits your wall best.

Will there be a smell?

There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.

Do you hold any approvals?

Yes. We’re approved under the ARBOMaster scheme.

Do you have insurance?

Yes. We are fully insured, and we can confirm the details when we quote.

Will it make a mess?

No. We protect the surfaces around the joints, and we tidy up before we go.

What is backing rod for?

We fit closed-cell backing rod wherever the joint depth needs controlling. It controls the depth and stops the sealant bonding to the back, so the joint can move.
