Sand Mastic in Knightsridge
Traditional burnt sand mastic around sash and case windows and doors in stone and brick for homes and businesses in Knightsridge and across West Lothian. ARBOMaster approved applicators, fully insured, with a one-year guarantee.

When it is not the sealant
Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:
- Sash cords, weights and draught-proofing of the sashes
- Cracked or broken glass
- Rotten sashes, sills or window boxes (a joiner’s job)
If you are not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer.
Surfaces we seal
- Stone surrounds
- Sash and case windows
- Timber door frames
- Period & listed homes
- Tenement windows
- Brick reveals
Sand mastic in Knightsridge
Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditional guidance is not to paint over it and we will advise if you are redecorating. We work on stone surrounds, brick reveals and period & listed homes, and people most often call us about mastic that needs renewing before redecorating and open joints round the window box.
In and around a place like Knightsridge, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill.
Our work is backed for twelve months, in Knightsridge and everywhere else we cover.

What else we do in Knightsridge
Do you need sand mastic in Knightsridge?
Water gets into small cracks in the mastic and pushes it out. Exposed elevations normally fail first.
It’s worth asking for a quote if you see:
- Gaps round a timber door in stone or brick
- Gaps where the frame meets the masonry
- Old sand mastic that has cracked, crumbled or fallen out
- Mastic that needs renewing before redecorating
Rented homes near Livingston North station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.
What your quote should include
- How hidden problems are handled
- How the joint is cleaned and prepared
- Who does the work, and how experienced they are
- What the quote includes, VAT included or not
What happens if it’s left?
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. Around Knightsridge, water from a failed joint in an older stone home can soak into timber and plaster.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and agree the price before starting.
Why Knightsridge clients choose us
- Full insurance on every job

Questions from Knightsridge
Do you cover Knightsridge for sand mastic?
Yes. We work across all of Scotland, and Knightsridge is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing, and we will give you a clear quote.
Can you help a landlord with a rental near Livingston North station?
Yes, we work for letting agents and landlords. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we will give you a clear price.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Do you offer different sealant colours?
Yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before work begins.
How long does the job take?
It depends on the size of the job, but as a guide it takes a few hours per window, depending on the condition of the joints. We will tell you when we quote.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Can sand mastic be painted?
It’s traditionally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Ask us before painting near the mastic
- Get any rot dealt with first
- Look over the window mastic once a year
- Don’t run silicone over sand mastic
Don’t run silicone over the new mastic. If anything cracks, get it looked at rather than patching it.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry so early renewal protects both.
How it works
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours per window, depending on the condition of the joints. Somewhere like Knightsridge may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Clear the area around the work
- Let us know about earlier repairs to the joints

Knightsridge homes and the weather
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Historic houses like Howden House (about 1.1 miles south) are a reminder that the area around Knightsridge has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you look after a building such as Inveralmond Community High School, its window and door frames need their mastic kept sound, just like a home’s. If you live in an older home near St Andrew's Church, the joint between an old wall and a newer frame is generally the first place rain gets in.
