About our sand mastic in Westwoodhill
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. Typical jobs include gaps between timber frames and stone or brick and cracked mastic round a front door frame, on brick reveals, period & listed homes and tenement windows.
In and around a place like Westwoodhill, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain.

What happens on the day
On the day, we look over the joints with you first. We protect the surfaces around the joints before any work begins. The work generally takes a few hours for a single window, longer for several. Somewhere like Westwoodhill may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Clear items away from the joints we are working on
- Keep children and pets away from the work area

Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Can I do it myself?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Questions from Westwoodhill
I let a flat near Hairmyres station. Can you help?
Yes, we work for landlords and agents. You can email us at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before we start.
Is Westwoodhill in your area for sand mastic?
Yes, Westwoodhill is within the area we cover. Our work covers the whole of Scotland. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
What guarantee comes with the work?
You get our one-year guarantee to all our work.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
What information do you need?
A short description and the location, with pictures by email if possible. We’ll ask anything else we need to know.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Westwoodhill, along with the rest of our area.
Should I use sand mastic or silicone?
It depends on the window. On many period windows, sand mastic looks right and suits the building and newer frames generally get a flexible sealant.
Is consent needed for window work on a listed home?
Yes, it’s worth checking. Your local planning authority can say if consent is needed for work on a listed home or in a conservation area.
How to look after the new joints
A little care helps the new joints last. Our advice:
- Check the mastic when you check the paintwork
- Plan mastic work ahead of painting
- Check with your local planning authority if your home is listed
- Get any rot dealt with first
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
Sound mastic protects the frame. Once it fails, water can sit against the timber, which can lead to rot.
Windows and doors in Westwoodhill
The west of Scotland is wetter than the east, which means the mastic around older windows and doors has to cope with a lot of rain. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Rented homes near Hairmyres station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

Signs you need sand mastic in Westwoodhill
Rain on the window surround works into any crack and pushes it out. Windows facing the weather tend to go first.
Any of these means the joints need attention:
- Mastic round period door frames that has failed
- Open joints round the window box
- Failed mastic on an exposed elevation
- Old sand mastic that has cracked, crumbled or fallen out
If you look after a building such as Duncanrig Secondary School, the mastic around its windows and doors needs looking after like any other building’s.
