Sand mastic for homes and businesses in Bonnington
Across Bonnington, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand for a neat, traditional finish. We work on timber door frames, stone surrounds and tenement windows, and common reasons people get in touch are draughts and rain around sash boxes and old cement repairs round a window that have failed.
Scotland’s cities are full of stone-built tenements and terraces, in sandstone or granite. Natural stone around older windows needs a sealant that will not mark or attack it, so acetoxy silicones, which can attack some stone, are best avoided.
You are covered for a year from the day we finish. If anything is not right with it, drop us a line at info@mrmastic.co.uk.

Can I do it myself?
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.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

Why act early in Bonnington
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and blends with the stone or brick. In a Scottish city tenement, failed sealant affects more than one flat: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.

Bonnington homes and the weather
Bonnington is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
Rented homes near Edinburgh Waverley station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. Historic houses such as Whitefoord House, about 1.3 miles south, show how far back building around Bonnington goes.

Common questions in Bonnington
Who arranges sealant work on the shared parts of a tenement in Bonnington?
It usually goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 covers the common parts where the deeds don’t.
Does the coastal weather in Bonnington affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
What is sand mastic?
It’s the traditional filler for the joint round timber windows and doors. It’s made with sand and a linseed-oil-based binder.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
How do I get a quote for sand mastic in Bonnington?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You will get a clear quote before any work starts.
Do I need permission for sand mastic on a listed building?
It’s best to ask your local planning authority first. Like-for-like sand mastic is often the preferred finish, but they decide.
Is it possible to take out silicone and use sand mastic instead?
Yes, we do this often. All the old silicone is removed first so the mastic beds in well.
Is there any odour?
Possibly a little. It fades as the sealant cures, and ventilation helps.
What we do, step by step
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to a full day, depending on how many windows, and the area is left clean. In a city area like Bonnington, parking may be by permit or pay-and-display, so tell us what’s nearby. If you’re in a flat, let us know how we get in at the street door.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Getting ready for the visit
- Keep children and pets away from the work area
- Mention if the joints have been sealed before
- For indoor joints, keep the area dry beforehand if you can

Advice
For landlords and businesses
Letting agents often deal with us directly. Tell us the address, the job and how access works.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Aftercare tips
To keep the joints looking good and working properly:
- Have rotten timber repaired before new mastic goes in
- Leave the new mastic unpainted
- Look over the window mastic once a year
- Avoid heavy scraping on the mastic joint
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
