How we handle sand mastic in Bielside
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. If you have mastic that needs renewing before redecorating and modern sealant on a period surround, we can put it right.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
Our work is backed for twelve months, in Bielside and everywhere else we cover.

What sand mastic looks like in Bielside
Bielside is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
For an older house near a landmark such as Belhaven Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What else we do in Bielside
How it works
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes a few hours per window, depending on the condition of the joints. For a place like Bielside, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Preparing for the visit
- On commercial sites, let us know about site rules
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints

Different surfaces, different methods
Timber door frames
Sand mastic is used round timber door frames too. The method is the same as for windows.
Sash and case windows
The mastic round a sash window is on show, so a neat, even finish matters.
Why it’s worth doing now in Bielside
Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Around Bielside, 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.
A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, email us at info@mrmastic.co.uk and we’ll give you an honest view and a quote.

For landlords and businesses
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will quote.
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
Can I do it myself?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Signs you need sand mastic in Bielside
Water gets into small cracks in the mastic and loosens it further. Windows facing the weather tend to go first.
The problems people generally mention when they call are:
- Window mastic to renew ahead of painting
- Old sand mastic that has cracked, crumbled or fallen out
- Draughty sash windows at the surround
- Old cement repairs round a window that have failed
Rented homes near Dunbar station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

FAQs for Bielside
Does the coastal weather in Bielside affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Do you work for landlords with property near Dunbar station?
Yes, landlords and agents are among the people we work for. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
What does sand mastic cost?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
Is there any odour?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Which is right for my windows, sand mastic or modern sealant?
Sand mastic normally suits period timber windows best. On modern frames, we’d normally use a flexible sealant, and we will explain why.
