Trusted sand mastic in Newtongrange

DIY versus a professional finish

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

Sand mastic in Newtongrange, done properly

Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. We are often asked to deal with wind and rain getting in round a sash window and old cement repairs round a window that have failed, on sash and case windows, tenement windows and period & listed homes.

In and around a place like Newtongrange, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.

Each job carries a 12-month guarantee, whatever its size.

Your questions about sand mastic in Newtongrange

Can you do sand mastic in Newtongrange?

Yes. Our work covers the whole of Scotland, and Newtongrange is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.

Can you help a landlord with a rental near Newtongrange station?

Yes. We work for landlords and letting agents as well as householders. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.

What’s sand mastic made of?

It’s a mix of sand and a linseed-oil-based binder. It’s applied by hand and finished to sit neatly against the masonry.

Can you match the sealant colour?

Most of the time, yes. We’ll explain which colours are available.

Is it OK to seal over old sealant?

No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.

Does someone need to be in?

We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.

Will the old sealant be removed?

Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

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

Often, yes. Once the silicone is out and the joint prepared, sand mastic is applied by hand.

For landlords and businesses

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.

For anyone letting property in or around Newtongrange, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs, and photos by email help.

Surface by surface

Timber door frames

Doors face weather and wear and the mastic can crack early. It’s renewed by hand.

Stone surrounds

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

How the visit works

Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours per window, depending on the condition of the joints. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.

  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. We pack any deep gaps so the mastic sits at the right depth.
  4. The mastic is mixed, pressed into the joint by hand and shaped.
  5. The mastic is finished to sit tidily against the stone or brick.

Getting ready for the visit

  • Tell us about access, such as stairs, a lift or high-level joints
  • Tell us about any previous sealing or DIY attempts
  • For indoor joints, keep the area dry beforehand if you can

Signs you need sand mastic in Newtongrange

Water gets into small cracks in the mastic and loosens it further. Exposed elevations usually fail first.

Most people get in touch after spotting something like this:

  • Cement or filler used on old window joints that has cracked
  • Mastic that needs renewing before redecorating
  • Weathered mastic on the most exposed windows
  • Wind and rain getting in round a sash window

In the older streets around Newtongrange Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Aftercare tips

After the cure time, these simple habits help:

  • Don’t run silicone over sand mastic
  • Do not paint over the new mastic
  • Ask a joiner to look at soft timber first
  • Check with your local planning authority if your home is listed

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

Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.

What sand mastic looks like in Newtongrange

Historic houses like Melville Castle (about 2.3 miles north-west) are a reminder that the area around Newtongrange has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.

Schools such as Newbattle Community High School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Rented homes near Newtongrange station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.
