Bimbister: your questions answered
Can you do sand mastic in Bimbister?
Yes. We work across all of Scotland, and Bimbister is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
Does living near the coast affect sand mastic in Bimbister?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Is sand mastic better than silicone for my windows?
Sand mastic usually suits period timber windows best. On modern frames, we’d normally use a flexible sealant, and we will explain why.
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 it possible to paint over sand mastic?
Traditional guidance is not to paint over sand mastic. If you’re redecorating the window, ask us first and we will advise.
Do you work for landlords and businesses?
Yes. We work in homes, commercial premises and hotels.
Can I choose the sealant colour?
Most of the time, yes. We will tell you which colours the right product comes in.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
About our sand mastic in Bimbister
Sand mastic suits most period window surrounds. Newer frames generally get a flexible sealant instead and we’ll explain which is best for yours. Typical jobs include draughts and rain around sash boxes and weathered mastic on the most exposed windows, on brick reveals, period & listed homes and timber door frames.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
There’s a 12-month guarantee on every job.

How it works
We bring everything the job needs with us. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take a few hours per window, depending on the condition of the joints. Around Bimbister, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- 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.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any water getting in
- Mention any parking rules near the property

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. Whenever you are ready, email us at info@mrmastic.co.uk.

How to look after the new joints
A little care helps the new joints last. We recommend:
- Clear gutters so water does not pour onto the windows
- Have rotten timber repaired before new mastic goes in
- Do not run silicone over sand mastic
- Look over the window mastic once a year
Don’t touch or press the mastic while it hardens. It skins over quickly but needs longer to fully harden.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
For landlords and businesses
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
For anyone letting property in or around Bimbister, several properties can go on one quote. Just tell us the addresses and what each one needs, and pictures by email help.
Sand mastic in Bimbister: local notes
Bimbister is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
For an older house near a landmark such as Grimeston Congregational Chapel, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Bimbister is about 9 miles west of Kirkwall, in the Orkney Islands. If you need sand mastic in Bimbister, please email us at info@mrmastic.co.uk for a quick quote. We’re based in Crawley and cover the Orkney Islands. Bimbister is one of 51 places in the Orkney Islands we cover for sand mastic.

What else we do in Bimbister
Why deal with it now?
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic won’t stop the gaps and traditional guidance is to leave the new mastic unpainted. In an older home around Bimbister, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

What we’re called out for in Bimbister
Over the years, sand mastic weathers. It hardens, cracks and starts to come away from the frame or the masonry.
Most people get in touch when they notice something like this:
- Silicone on a period window that looks wrong
- Draughts and rain around sash boxes
- Mastic round period door frames that has failed
- Mastic dropping out of the joint
Around Bimbister, as everywhere, sand mastic is only as good as the preparation behind it.
Questions to ask before you book
- Is VAT in the price?
- What preparation is included
- How hidden problems are handled
- Who turns up on the day
Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
