How we handle external mastic in Ramsey Island

Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two where a rigid filler would soon crack. We work on render & cladding joints, concrete & block and façade panels, and common reasons people get in touch are water getting into walls through failed joints and panel joints letting water in.

In a village or hamlet like Ramsey Island, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.

Whatever the size of the job, it’s backed by our 12-month guarantee in Ramsey Island and across Essex.

Landlord and commercial work in Ramsey Island

Mouldy or split sealant often shows up at the end of a tenancy. Several properties can be quoted together.

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will give you a quote.

What we do, step by step

On the day, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before work begins. The work usually takes anything from a few hours to several days, depending on the building. Somewhere as small as Ramsey Island, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  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. Joint faces are cleaned back and primed if the sealant needs 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

  • Let us know about earlier repairs to the joints
  • Tell us if parking is tricky
  • Clear items away from the joints we’re working on

Related advice

Leave it or put it right?

Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. Older cottages and farmhouses around Ramsey Island can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Why us?

  • Colour agreed with you before we start
  • A 12-month guarantee on all work
  • Anti-fungal sanitary silicone in wet areas
  • An ARBOMaster approved applicator

When it isn’t the sealant

New sealant cannot fix everything, and we’d rather say so up front. It will not solve:

  • Damp that is not coming from the joint
  • Cutting new joints into brickwork, which is building work rather than sealant work
  • Render that’s blown, hollow or coming away

If you are not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.

Joints and surfaces we work on

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

What the job involves on each surface

Brickwork movement joints

Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so the sealant in it must stay soft and stretchy.

Copings and trims

A failed coping joint lets water into the top of the wall. Resealing them is a small job that protects a lot.

Looking after it afterwards

After the cure time, these simple habits help:

  • Leave the joints unpainted unless we have said otherwise
  • Have failed joints looked at early
  • Keep water from gutters off the wall
  • Point out the joints to other trades

Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.

Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.

FAQs for Ramsey Island

Do you cover smaller places like Ramsey Island?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Do you work for landlords with property near Southminster station?

Yes, we work for landlords and letting agents. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.

Do I need to be at home?

Access is agreed with you when the job is booked. Indoors, that usually means someone at home.

Are you insured?

Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.

What’s an expansion joint in brickwork?

A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It’s sealed with a flexible sealant, not mortar.

What colours does the sealant come in?

We choose a sealant colour to suit the brick, stone or render so the joint blends in. Exterior sealants come in a good range of colours.

Do you hold any approvals?

Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.

Do the sealants smell?

Sometimes, a little. It fades as the sealant cures.

External mastic in Ramsey Island: local notes

Ramsey Island is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

If you let a flat or house near Southminster station, split movement joints are easy to miss on a rental until damp shows inside. In the older streets around St Lawrence Church Centre, an extension built onto an older house moves differently, and the joint between them takes the strain.
