- Failed mastic on an exposed elevation
- Old cement repairs round a window that have failed
How we handle sand mastic in Boghead
Sand mastic suits most period window surrounds. Newer frames generally get a flexible sealant instead, and we will talk through which suits your home. We’re often asked to deal with gaps round a timber door in stone or brick and draughty sash windows at the surround, on tenement windows, period & listed homes and brick reveals.
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.
The work is covered for a year after we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

FAQs for Boghead
Do you cover smaller places like Boghead?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Do you cover Boghead for sand mastic?
Yes, Boghead is within the area we cover. Our work covers the whole of Scotland. You can email us at info@mrmastic.co.uk and tell us what needs doing.
Can new sealant go over the old?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Can you match the sealant colour?
We help you choose a colour that suits. The product needed can limit the range.
Are you fully insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Where is Mr Mastic based?
We are based in Crawley, and we work across South East England, London and Scotland.
How long will you be here?
It depends on the size of the job, but most jobs take anything from a few hours to a full day, depending on how many windows. We’ll give you a better idea when we quote.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected.
What happens if it’s left?
New sash windows are a major, costly change and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. In a place like Boghead, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
What you pay reflects the work, not guesswork. That is why we ask a few questions first and give you a clear quote before any work starts.

How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Get any rot dealt with first
- Plan mastic work ahead of painting
- Ask the planning authority about consent for listed or conservation-area homes
- Look over the window mastic once a year
Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.
Sound mastic protects the frame. Failed mastic lets water reach the timber and timber that stays wet can rot.
The process
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a few hours for a single window, longer for several, including the tidy-up. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Getting ready for the visit
- Tell us about any water getting in
- For indoor joints, keep the area dry beforehand if you can
- Keep pets and children clear of the area while we work
Getting a quote
Getting a quote is simple: let us know what needs doing and where and its rough size. A few pictures by email make the job easier to understand.

Quotes for sand mastic in Boghead
For a quick quote, just ask. The main things that affect it are:
- Whether old sealant or filler has to be cut out
- When we can work, for business premises
- The type of sealant required
- The number of rooms or windows
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Can I do it myself?
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.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

What sand mastic looks like in Boghead
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
