About our sand mastic in Swinton

Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. Renewing it closes the gap and tidies the surround. We work on tenement windows, period & listed homes and timber door frames, and people most often call us about silicone on a period window that looks wrong and patchy fillers round a sash window.

In and around a place like Swinton, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.

We stand behind the work with a one-year guarantee, so you are covered after we’ve gone.

DIY versus a professional finish

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. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

How it works

Once we’re on site, 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. For a place like Swinton, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.

  1. First, we look at the surrounds with you and agree what needs doing.
  2. Old, loose mastic is raked out and the joint cleaned.
  3. Large voids are packed out first, so the mastic isn’t too thick.
  4. We mix the sand mastic and apply it by hand, shaping it to the joint.
  5. The mastic is finished to sit tidily against the stone or brick.

Swinton questions

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

Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear quote.

Is Swinton in your area for sand mastic?

Yes. Our work covers the whole of Scotland, and Swinton is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will send you a clear quote.

Will there be a smell?

It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.

Do you work for hotels and businesses?

Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.

Should I use sand mastic or silicone?

Sand mastic normally suits period timber windows best. Modern frames normally suit a flexible sealant, and we will explain why.

How do I get a quote for sand mastic in Swinton?

We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You will get a clear quote before any work starts.

Will you leave a mess?

No. The area is protected while we work and cleaned up afterwards.

What should I tell you?

Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.

Do you need sand mastic in Swinton?

Timber swells and shrinks with the weather. That movement opens up the mastic joint over time.

Most people get in touch after spotting one of these:

  • Window mastic to renew ahead of painting
  • Gaps between timber frames and stone or brick
  • Old sand mastic that has cracked, crumbled or fallen out
  • Wind and rain getting in round a sash window

If you live in an older home near St John's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Choosing a sealant specialist

Aftercare tips

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

  • Renew mastic before redecorating the windows
  • Leave the new mastic unpainted
  • Do not run silicone over sand mastic
  • Find out about consent before window work on a listed home

Look at the mastic when you look over the windows. Small cracks are easier to deal with early.

Good mastic helps keep the frame dry. Once it fails, water can sit against the timber, which can lead to rot.

What affects the quote in Swinton

The price is agreed before any work begins. It takes into account:

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

The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.

What to tell us for a quote

Photos by email are helpful but not essential. Try to tell us:

  • How we’d reach the joints
  • The problem you’ve noticed
  • Photos by email, if that is easy
  • How many joints, rooms or windows are involved

If you are in Swinton and need sand mastic, send an email to info@mrmastic.co.uk. A short description of the job and where it is helps us quote, and you will get a clear quote before any work starts.

Landlord and commercial work in Swinton

What sealant work cannot fix

  • Decayed frames that need repair
  • Putty and glazing repairs

What sand mastic looks like in Swinton

Swinton is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.

For site and facilities teams at buildings such as St. Leonard's Secondary School, its window and door frames need their mastic kept sound, just like a home’s. If you let a flat or house near Easterhouse station, older sash windows in a rental need their mastic kept sound to keep the weather out.
