Sand mastic in Netherton

About our sand mastic in Netherton

Across Netherton, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. We’re often asked to deal with failed mastic on an exposed elevation and mastic round period door frames that has failed, on stone surrounds, brick reveals and timber door frames.

Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill.

You are covered for a year from the day we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

How we quote for sand mastic

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

  • Any working-time requirements on site
  • Access and height
  • The number of rooms or windows
  • The type of sealant required

What you pay reflects the work, not guesswork. That is why we ask about the job first.

Asking for a quote

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

  • How we’d reach the joints
  • Where the property is
  • How many joints, rooms or windows are involved
  • If it’s domestic, commercial or a hotel

Need a quote? Please drop us a line at info@mrmastic.co.uk and tell us about the job. You’ll know what we plan to do, and what it will cost, before any work begins.

Why deal with it now?

A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and finishes neatly against the masonry. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.

Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, email us at info@mrmastic.co.uk and we’ll give you an honest view and a quote.

Why book with us

  • Anti-fungal silicone where joints get wet
  • Any old sealant cut out fully, not covered over
  • More than 20 years in sealant work
  • A 12-month guarantee on all work

Landlord and commercial work in Netherton

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

How the visit works

Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and clear up. It normally takes anything from a few hours to a full day, depending on how many windows. Outside jobs in Netherton need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors is not affected.

  1. Each surround is checked first.
  2. We rake out the old mastic and clean the joint.
  3. We fill deep gaps so the new mastic is not too thick.
  4. We point the joint with sand mastic by hand.
  5. The finish is dressed neatly.

Before we arrive

  • Mention any tricky access
  • Mention any parking rules near the property
  • Mention if the joints have been sealed before

Honest limits

To be straight with you, there are a few things sealant won’t fix:

  • Rotten sashes, sills or window boxes (a joiner’s job)
  • Sash cords, weights and draught-proofing of the sashes
  • Masonry that needs repairing

If you’re not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer.

Do you need sand mastic in Netherton?

Age is the main cause. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.

Look out for any of the following:

  • Failed mastic on an exposed elevation
  • Old cement repairs round a window that have failed
  • Gaps between timber frames and stone or brick
  • Draughty sash windows at the surround

Around Netherton, as everywhere, sand mastic is only as good as the preparation behind it.

What’s sand mastic made of?

It’s the traditional filler for the joint round timber windows and doors. It’s made with sand and a linseed-oil-based binder.

Is it worth trying it myself?

That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.

Is it possible to take out silicone and use sand mastic instead?

Yes. The silicone is cut out and the joint cleaned before the sand mastic goes in.

Do you work for letting agents?

Yes, often. We can quote for several properties at once, and between tenancies is a good time for the work.

Sand mastic in Netherton: local notes

Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. 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.

Homes close to Netherton Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

DIY versus a professional finish

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
