Trusted external mastic in Nine Ashes

External mastic for homes and businesses in Nine Ashes

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. The colour is chosen to suit the brick or render. Typical jobs include gaps where render, brick and frames meet and hard, crazed mastic that has stopped moving, across façade panels, copings & trims and joints between brick and frames.

Somewhere as small as Nine Ashes, homes and farm buildings often face open ground, 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.

All of our work is guaranteed for twelve months.

Keeping the joints in good condition

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

  • Never let anyone fill a movement joint with mortar
  • Ask before painting over external sealant
  • Point out the joints to other trades
  • Keep soil, plants and ivy away from the joints

Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.

Small splits are the time to act. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.

Do you need external mastic in Nine Ashes?

UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.

Look out for any of the following:

  • Sealant pulling away from one side of the joint
  • Failed seals between different materials
  • Old sealant gone brittle and cracked
  • Movement joints filled with mortar instead of sealant

Homes close to Church of St Laurence include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

Our hiring checklist

Why it’s worth doing now in Nine Ashes

Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. Older cottages and farmhouses around Nine Ashes 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 price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Why choose Mr Mastic in Nine Ashes

  • A sealant colour to suit the surroundings
  • A 12-month guarantee on all work
  • A choice of colours where the product allows
  • Experience in homes, commercial sites and hotels

See our cost guide or customer reviews.

What affects the quote in Nine Ashes

The price is agreed before any work begins. It’s based on:

  • Any mould that needs treating
  • The number and length of the joints
  • The old material and how stubborn it is
  • The type of sealant required

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.

What to tell us for a quote

To make quoting easier, let us know:

  • Pictures of the joints, sent by email
  • If someone has resealed it before
  • Whether it’s a home or a business
  • Roughly how big the job is

If you are in Nine Ashes and need external mastic, phone 0345 464 0079 or drop us an email. A short description of the job and where it is helps us quote, and you will get a clear quote before we start.

Landlord and commercial work in Nine Ashes

Letting agents and landlords in Nine Ashes can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order.

We also work for property managers and facilities teams. We can quote a run of properties together.

The process

A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a few hours for a handful of joints, longer for a whole elevation. In a small place like Nine Ashes, access is normally the main thing to plan. 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. Backing rod sized to the joint goes in to set the depth.
  5. The exterior sealant is applied, tooled and checked along its length.

Before we arrive

  • Mention any sign-in or site rules at work premises
  • Mention any parking rules near the property
  • For indoor joints, keep the area dry beforehand if you can

What external mastic looks like in Nine Ashes

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. Historic houses like Ingatestone Hall (about 4.6 miles south-east) are a reminder that the area around Nine Ashes has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.

If you look after a building such as Blackmore Primary School, larger buildings have long runs of movement joint that eventually need resealing. If you let a flat or house near Ingatestone station, split movement joints are easy to miss on a rental until damp shows inside.
