Frames and glazing around Bragar
Bragar is within about 1 mile of 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. On the islands, wind and salt spray are hard on outside sealant.
In and around Bragar, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

Sand mastic in Bragar
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. If you’re dealing with crumbling sand mastic round a window and gaps between timber frames and stone or brick, we can put it right, on brick reveals, sash and case windows and tenement windows alike.
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.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
What affects the cost of sand mastic
Every job gets its own quote. This is what makes a difference:
- Working hours on commercial sites
- Whether there’s mould to deal with
- How easy the joints are to reach
- The old material and how stubborn it is
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Helping us quote
Photos help, but a description is a good start. Please mention:
- Photos by email, if that’s easy
- Roughly how big the job is
- Any previous sealing or DIY work
- What the problem is, such as mould, gaps, leaks or cracking
For a quick quote, get us on the phone, or email us if that’s easier. Describe what needs sealing and we’ll talk you through the work before giving you a price.
How to look after the new joints
A little care helps the new joints last. Our advice:
- Clear gutters so water does not pour onto the windows
- Ask the planning authority about consent for listed or conservation-area homes
- Check the mastic when you check the paintwork
- Have rotten timber repaired before new mastic goes in
Avoid painting over the new mastic, as traditional guidance advises. Ask us before any decorating around it.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
How the visit works
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours per window, depending on the condition of the joints. Outside jobs in Bragar need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic isn’t too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
How to prepare
- Mention if the joints have been sealed before
- Clear the area around the work
- Keep pets and children clear of the area while we work

Questions from Bragar
Does living near the coast affect sand mastic in Bragar?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are generally the first to need attention.
Is Bragar in your area for sand mastic?
Yes, Bragar is within the area we cover. Our work covers the whole of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
How long does sand mastic take?
Most jobs take a few hours per window, depending on the condition of the joints, including the preparation. We will confirm how long when we quote.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Can tenants book the work?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
Can you replace silicone on a period window with sand mastic?
Often, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.
What we’re called out for in Bragar
Shallow joints are a common cause. A thin layer does not hold well, which is why we pack deep voids first and get the depth right.
Keep an eye out for these signs:
- Weathered mastic on the most exposed windows
- Open joints round the window box
- Cement or filler used on old window joints that has cracked
- Mastic dropping out of the joint
For jobs in and around Bragar, choosing the right material for each joint is as important as a tidy finish.
