How we handle sand mastic in West Calder
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. We rake it out and renew it and tidies the surround. If you are dealing with mastic worn away on windows facing the weather and draughts and rain around sash boxes, we can put it right, whatever the surface.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
All of our work is guaranteed for twelve months, in West Calder and everywhere else we cover.

Howden House, about 3.6 miles north-east, is one of the historic houses in the wider area around West Calder, and older homes nearby need a sealant that suits their walls. For landlords with property near West Calder station, any sash windows need sound mastic to keep draughts and rain out.

Why act early in West Calder
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. Around West Calder, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
The cost reflects the work involved, not guesswork. That is why we ask about the job first and agree the price before starting.

West Calder questions
Do you cover smaller places like West Calder?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near West Calder station?
Yes, landlords and agents are among the people we work for, 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 price.
Are you insured?
Yes. We’re fully insured.
Is sand mastic better than silicone for my windows?
That depends on your windows. Period windows in stone or brick normally suit sand mastic, while modern frames normally get a flexible sealant.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Can you replace silicone on a period window with sand mastic?
Often, yes. Once the silicone is out and the joint prepared, sand mastic is applied by hand.
When will the new mastic be hard?
The surface skins quite quickly and it hardens fully over a longer time. Timing depends on the weather and the joint.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Look over the window mastic once a year
- Plan mastic work ahead of painting
- Ask a joiner to look at soft timber first
- Avoid heavy scraping on the mastic joint
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
An open joint round the box lets weather through. Left, the gap tends to get bigger.
What happens on the day
When we arrive, we look over the joints with you first. Surfaces next to the work are protected before any work begins. The work generally takes a few hours for a single window, longer for several. For a place like West Calder, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can

Related advice
Can I do it myself?
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.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
