External mastic in Asheldham

External mastic in Asheldham, done properly

We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it, and we do not skip that step. We work on joints between brick and frames, façade panels and concrete & block, and common reasons people get in touch are joints where the bead has come unstuck and hard, crazed mastic that has stopped moving.

Outside joints can only be sealed when they’re dry, so work in Asheldham is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.

All our work comes with our one-year guarantee.

Aftercare tips

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

  • Show decorators and builders where the movement joints are
  • Clear growth from the base of walls and joints
  • Avoid pressure-washing directly into sealant joints
  • Keep movement joints as flexible joints, not mortar

Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.

Small splits are the time to act. Then it’s a straightforward cut-out and reseal.

Outside joints around Asheldham

Asheldham is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Letting a property close to Southminster station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Why it’s worth doing now in Asheldham

Running new sealant over the old bead rarely lasts. New sealant doesn’t bond well to old, weathered sealant, so the old joint is cut out fully first. Around Asheldham, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

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. Your quote takes all of that into account.

Why book with us

  • We leave the area clean and tidy
  • 12-month guarantee on every job
  • 20+ years of sealant experience
  • Colour picked to suit the job

Questions from Asheldham

Does living near the coast affect external mastic in Asheldham?

Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.

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

Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.

Are you an approved applicator?

Yes. We hold ARBOMaster approved applicator status and we are fully insured too.

Can you reach joints on upper floors?

That depends on how high the joints are and the ground below. Ground-floor joints are simple; for higher ones, send details and we will confirm the access.

Is it OK to seal over old sealant?

No, it will not last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.

What colours does the sealant come in?

The aim is a neat, even joint in a colour that suits the wall. We’ll talk through colour options before work begins.

Can you quote for more than one area?

Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.

Do you remove the old sealant?

Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.

Do you need external mastic in Asheldham?

Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.

Any of these means the joints need attention:

  • Joints where the bead has come unstuck
  • Movement joints filled with mortar instead of sealant
  • Old sealant gone brittle and cracked
  • Cracked joints where brick meets render or frames

In the older streets around Church of St James, the joints between older walls, newer extensions and the roofline need a sealant that can move.

What your quote should include

  • Whether the sealant suits the joint
  • What happens if they find a problem under the old sealant
  • Which colour the sealant will be
  • What guarantee comes with the work

10 questions to ask before you book

What we do, step by step

All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on the building. Somewhere as small as Asheldham, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  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. We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
  5. A flexible exterior sealant is applied and tooled in a colour to suit the wall.

Before we arrive

  • Plan for the work area to be out of bounds to pets and children
  • Tell us about access, such as stairs, a lift or high-level joints
  • Let us know about earlier repairs to the joints

What affects the quote in Asheldham

You’ll get a clear quote before any work starts. It’s based on:

  • Whether there’s mould to deal with
  • The size of the job
  • How many areas need sealing
  • Access and height

Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Asking for a quote

When you contact us, these details help:

  • Any previous sealing or DIY work
  • If it’s domestic, commercial or a hotel
  • Any access issues, like height or stairs
  • What the problem is, such as mould, gaps, leaks or cracking

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email pictures if that’s easy.

Surface by surface

Copings and trims

Copings expand and contract through the day, so a flexible sealant suits them best in all weathers.

Brickwork movement joints

People sometimes point up a brick movement joint by mistake. If that’s happened, we rake it out and reseal it properly.

Honest limits

In fairness, there are a few things sealant will not fix:

  • Subsidence or other structural problems
  • Cutting new joints into brickwork, which is building work rather than sealant work
  • Damp from another source, such as a leaking gutter or a bridged damp-proof course

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