Sand mastic in Hermiston
Sand mastic does not last for ever and gaps open up round the frame. We rake it out and renew it and tidies the surround. If you have cracked mastic round a front door frame and draughts and rain around sash boxes, we can put it right, on stone surrounds, sash and case windows and period & listed homes alike.
Outdoor sealant needs a dry surface, so window work around Hermiston is planned around the weather. Let us know about access to every frame, including any upstairs.
Every job is covered by our one-year guarantee.

Why act early in Hermiston
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic won’t stop the gaps, and the new mastic is traditionally left unpainted. In an older home around Hermiston, damp from a failed joint can get into timber and plaster.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.

Looking after it afterwards
To keep the joints looking good and working properly:
- Find out about consent before window work on a listed home
- Clear gutters so water does not pour onto the windows
- Leave the new mastic unpainted
- Ask a joiner to look at soft timber first
Do not run silicone over the new mastic. If you see a crack, ask us to take a look before trying a quick fix.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
Hermiston homes and the weather
Edinburgh’s Old and New Towns are a UNESCO World Heritage Site, with sash windows throughout the Georgian New Town. If a home is listed or in a conservation area, it’s worth checking with the council before changing the look of windows or walls. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Rented homes near Edinburgh Park station change hands often, and any sash windows need sound mastic to keep draughts and rain out. Around Hermiston, as everywhere, sand mastic is only as good as the preparation behind it.

Questions from Hermiston
Can you help a landlord with a rental near Edinburgh Park station?
Yes, rental work is part of what we do. You can send an email to info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before work begins.
Do you cover Hermiston for sand mastic?
Yes. Our work covers the whole of Scotland, and Hermiston is part of that. You can email us at info@mrmastic.co.uk and let us know what needs doing, and we will give you a clear price.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Where do you work from?
We are based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we’re done.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Is it possible to paint over sand mastic?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we will advise.
Is consent needed for window work on a listed home?
It’s best to ask your local planning authority first. Like-for-like sand mastic is often the preferred finish, but they decide.
Different surfaces, different methods
Timber door frames
Sand mastic is used round timber door frames too. We renew it the same way as on windows.
Period and listed homes
On a listed home or in a conservation area, the right material matters. Like-for-like sand mastic is usually favoured.
The process
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. It normally takes a few hours per window, depending on the condition of the joints. Around Hermiston, distance and access matter more than parking. 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.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- Move anything stored near the joints
- Let us know about stairs, lifts or work at height
- Let us know about earlier repairs to the joints

If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think.

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 matched to the joint and its conditions, and the work is guaranteed for a year.
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.
