About our sand mastic in Westfield
We renew sand mastic around sash windows and doors set in stone or brick. The old mastic is raked out, and new mastic is applied and shaped by hand. We work on period & listed homes, sash and case windows and timber door frames, and people most often call us about open joints round the window box and modern sealant on a period surround.
Outdoor sealant needs a dry surface, so window work around Westfield is planned around the weather. Tell us about access to all the windows and doors, upstairs included.
Our work is backed for twelve months.

Frames and glazing around Westfield
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. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
For landlords with property near Armadale station, any sash windows need sound mastic to keep draughts and rain out.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Westfield questions
Is Westfield within the area you cover?
Yes, we do. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Armadale station. Can you help?
Yes, we work for landlords and agents. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we will give you a clear quote.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.
Can I choose the sealant colour?
We help you choose a colour that suits. The product needed can limit the range.
How much does sand mastic cost in Westfield?
Size, access and the old material all affect the cost. Ask us for a quote.
When something else is needed
Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:
- Rotten sashes, sills or window boxes (a joiner’s job)
- Masonry that needs repairing
- Sashes that need overhauling
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer before booking.
What we seal
- Timber door frames
- Period & listed homes
- Brick reveals
- Sash and case windows
- Stone surrounds
- Tenement windows

We also work for property managers and facilities teams. Several sites can go on one quote, and we’re fully insured.
Common problems we fix in Westfield
Previous repairs in cement or silicone often trap water or crack away. They do not move with the timber and we normally remove them.
It’s worth asking for a quote if you see:
- Old cement repairs round a window that have failed
- Modern sealant on a period surround
- Open joints round the window box
- Draughts and rain around sash boxes
In and around Westfield, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.
Before you book anyone
- Whether they’re fully insured
- Whether you can choose the colour
- How much experience the applicator has

Leave it or put it right?
Before painting the windows, it pays to renew the mastic. Painting over failed mastic doesn’t seal it, and the new mastic is traditionally left unpainted. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we will explain what it covers.

The process
The work is kept neat and contained to the area we are working on, so you can get on with your day. The job normally takes anything from a few hours to a full day, depending on how many windows, and we explain the cure time before we leave. For a place like Westfield, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- Mention if the joints have been sealed before
- Let us know about parking restrictions
- Try not to wet indoor joints just before the visit
