Work for landlords, hotels and businesses

In hotels, rooms out of use cost money, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.

Sand mastic in Carnoustie

Silicone on a period window often looks wrong and does not suit the building. Sand mastic is the traditional choice and we can swap the silicone for it. Common call-outs are for patchy fillers round a sash window and draughts and rain around sash boxes, on timber door frames, tenement windows and brick reveals.

Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.

We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

Carnoustie: your questions answered

Is Carnoustie within the area you cover?

Yes. Carnoustie is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.

I let a flat near Golf Street station. Can you help?

Yes, we work for landlords and agents. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before any work starts.

What sealant do you use?

Where do you work from?

We are a Crawley-based firm. Our area covers South East England, London and Scotland.

When will the new mastic be hard?

It forms a skin fairly soon, then hardens over a longer period. Timing depends on the weather and the joint.

Can you match the sealant colour?

Most of the time, yes. We will explain which colours are available and agree one before any work starts.

How much does sand mastic cost in Carnoustie?

Size, access and the old material all affect the cost. Call for a quick quote and we will talk you through it.

Windows and doors in Carnoustie

Carnoustie is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.

In the older streets around Carnoustie Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you look after a building such as Carnoustie High School, its window and door frames need their mastic kept sound, just like a home’s.

Carnoustie is about 6 miles east of Broughty Ferry, in Angus.

Can I do it myself?

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Common problems we fix in Carnoustie

Age is the main cause. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.

Any of these means the joints need attention:

  • Gaps between timber frames and stone or brick
  • Old sand mastic that has cracked, crumbled or fallen out
  • Tired mastic found when preparing windows for paint
  • Old cement repairs round a window that have failed

Letting a property close to Golf Street station? Then any sash windows need sound mastic to keep draughts and rain out.

Choosing a sealant specialist

Surface by surface

Stone surrounds

We take care not to mark the stone while raking out the old mastic.

Timber door frames

Period doors in stone or brick openings are often pointed with sand mastic. The method is the same as for windows.

What affects the cost of sand mastic

Jobs vary more than people expect. What affects the quote:

  • The type of sealant required
  • How much old sealant there is and how hard it is to remove
  • How easy the joints are to reach
  • Any working-time requirements on site

Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Ask us for a quote and we will explain what it covers.

Helping us quote

To make quoting easier, please include:

  • How many joints, rooms or windows are involved
  • Access, such as stairs, a lift or height
  • Whether it’s a home or a business
  • The address or postcode of the job

For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we will talk you through the work.

How to look after the new joints

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

  • Make sure water runs off the sill
  • Go gently near the mastic when preparing windows
  • Ask a joiner to look at soft timber first
  • Look over the window mastic once a year

Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look before trying a quick fix.

Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.

What we do, step by step

When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to a full day, depending on how many windows. Outdoor work around Carnoustie depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.

  1. Each surround is checked first.
  2. The joint is raked out and cleaned.
  3. We fill deep gaps so the new mastic isn’t too thick.
  4. New sand mastic is applied and shaped by hand.
  5. We finish the mastic to a tidy line.

How to prepare

  • Let us know if you’ve seen damp or leaks
  • Mention any sign-in or site rules at work premises
  • Move anything stored near the joints
