How the job changes by surface

Joints between dissimilar materials

Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant so neither cracks the other.

Copings and trims

Coping and trim joints face rain and sun head on. We reseal them with an exterior sealant suited to the material.

External mastic in New Winton

For buildings in New Winton, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. We work on brickwork movement joints, render & cladding joints and façade panels, and common reasons people get in touch are sealant that has lost its bond to the brick or render and movement joints with cracked, split or missing sealant.

In and around a place like New Winton, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering.

Big or small, it’s backed by our 12-month guarantee.

What happens on the day

We keep the work tidy and contained to the area we are working on. Expect the work to take a few hours for a handful of joints, longer for a whole elevation. For a place like New Winton, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.

  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.

Preparing for the visit

  • Mention any parking rules near the property
  • Keep pets and children clear of the area while we work
  • Tell us about any water getting in

Advice

Questions from New Winton

Does living near the coast affect external mastic in New Winton?

Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are generally the first to need attention.

Do you cover smaller places like New Winton?

Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.

Are you an approved applicator?

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

Can landlords and businesses book you?

Yes, regularly. Several properties can go on one quote, and between tenancies is a good time for the work.

Is there any odour?

Some sealants have a smell while they cure. Opening a window helps.

Can a movement joint be filled with mortar?

No. A mortar-filled joint cannot move, so the wall cracks somewhere else instead. Use a flexible sealant with backing rod.

What colours does the sealant come in?

The aim is a neat, even joint in a colour that suits the wall. Colour is agreed with you before we begin.

What is backing rod for?

Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back.

Quotes for external mastic in New Winton

We do not publish a price list, because jobs vary so much. What we look at:

  • Access and height
  • The product the joint needs
  • How much old sealant there is and how hard it is to remove
  • Whether there’s mould to deal with

There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please email us at info@mrmastic.co.uk.

Asking for a quote

There’s no need for technical detail. Just tell us:

  • Whether it’s a home or a business
  • Whether it has been sealed before
  • Pictures of the joints, sent by email
  • What the problem is, such as mould, gaps, leaks or cracking

Asking for a quote is easy: let us know what needs doing and where. A few photos by email make the job easier to understand.

Work for landlords, hotels and businesses

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

Housing providers, facilities teams and property managers book us too in New Winton and across East Lothian. We can quote a run of properties together, and we are fully insured for the work.

Can I do it myself?

A DIY attempt doesn’t rule out a professional job. We cut it out and start again.

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.

Why it’s worth doing now in New Winton

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. The correct repair is a flexible sealant with the right backing. In a place like New Winton, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, drop us a line at info@mrmastic.co.uk and we will give you an honest view and a quote.

Aftercare tips

Simple care keeps the joints in good condition. We recommend:

  • Keep soil, plants and ivy away from the joints
  • Fix overflowing gutters above sealed joints
  • Check the sealant is paintable before painting near it
  • Walk round the building once a year and look at the joints

Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.

A joint that has stopped moving pushes the movement elsewhere, usually as cracking in the brickwork or render nearby. Resealing it early helps prevent that.

New Winton buildings and the weather

New Winton 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 is hard on movement joints and outside wall joints, especially on the side facing the sea. With historic houses such as Hamilton House (about 2.9 miles north-west) nearby, there’s older building stock in the area around New Winton as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.

Historic houses such as Hamilton House, about 2.9 miles north-west, show how far back building around New Winton goes. If you let a flat or house near Prestonpans station, split movement joints are easy to miss on a rental until damp shows inside. Managing a site like Ross High School? Then its movement joints, gutters and trims need looking after like any other building’s.
