Surface by surface

Period and listed homes

Period homes look their best with traditional materials.

Stone surrounds

Old stone surrounds are often uneven, so the joint varies in width. Sand mastic is shaped by hand to suit.

About our sand mastic in Nitshill

Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditional guidance is not to paint over it, so ask us before you decorate. If you have draughts and rain around sash boxes and old cement repairs round a window that have failed, we can help.

Mastic can only go onto a dry joint, so outside work in Nitshill depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.

Our work is backed for twelve months.

What happens if it’s left?

A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic is the traditional material and blends with the stone or brick. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.

Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.

What you get with us

  • One-year guarantee on every job
  • We never seal over old sealant
  • Anti-fungal sanitary silicone in wet areas
  • We leave the area clean and tidy

DIY versus a professional finish

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

Nitshill questions

Is Nitshill in your area for sand mastic?

Yes. Our work covers the whole of Scotland, and Nitshill is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job, and we will give you a clear quote.

I let a flat near Nitshill station. Can you help?

Yes. We work for landlords and letting agents as well as homeowners. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear price.

Where is Mr Mastic based?

Our base is in Crawley, and we work across South East England, London and Scotland.

What guarantee comes with the work?

You get our 12-month guarantee to all our work.

Will there be a smell?

Possibly a little. It fades as the sealant cures.

Do you offer different sealant colours?

Yes. White, clear and grey are common, and other colours are available, and we’ll agree it with you first.

Can you seal over the old sealant?

No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.

What does sand mastic cost?

There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before work begins.

Nitshill homes and the weather

The west of Scotland is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.

Letting a property close to Nitshill station? Then any sash windows need sound mastic to keep draughts and rain out. Homes close to Barrhead South Parish Church include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in. For site and facilities teams at buildings such as Barrhead High School, larger buildings have plenty of frames, and the mastic around each one ages.

Nitshill is about 1 mile east of Barrhead, in East Renfrewshire. We carry out sand mastic for homes and businesses in Nitshill, as part of our work across East Renfrewshire. Nitshill is one of 17 towns and villages in East Renfrewshire where we work.

What sealant work cannot fix

Some problems need a builder, plumber or other trade rather than us:

  • Masonry that needs repairing
  • Whether work needs listed building consent
  • Sashes that need overhauling

If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.

Joints and surfaces we work on

  • Timber door frames
  • Sash and case windows
  • Tenement windows
  • Period & listed homes
  • Stone surrounds
  • Brick reveals

How we quote for sand mastic

We quote each job individually. These are the things that affect it:

  • Which sealant suits the joint
  • Any working-time requirements on site
  • Mould in or behind the old joints
  • The number and length of the joints

Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Call for a quick quote and we’ll explain what it covers.

Asking for a quote

When you call or email, these details help:

  • The rough size of the job
  • If it’s domestic, commercial or a hotel
  • How we’d reach the joints
  • What’s wrong with the joints now

Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. When it suits you, send an email to info@mrmastic.co.uk.

How to look after the new joints

Good habits help new joints last longer. Our tips:

  • Plan mastic work ahead of painting
  • Check the mastic when you check the paintwork
  • Make sure water runs off the sill
  • Go gently near the mastic when preparing windows

Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.

Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.

The process

Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a single window, longer for several. For a place like Nitshill, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.

  1. We look at the surrounds with you and agree the joints to renew.
  2. Old mastic and any loose material are raked out.
  3. Deep gaps are packed so the mastic sits at the right depth.
  4. The sand mastic is mixed and pressed into the joint by hand.
  5. We dress the finish so it sits neatly against the masonry.

How to prepare

  • Mention any parking rules near the property
  • Let us know if you’ve seen damp or leaks
  • Where the joints are inside, avoid wetting them before we arrive
