About our sand mastic in Eddleston
Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditional guidance is not to paint over it and we’ll advise if you’re redecorating. Common call-outs are for mastic round period door frames that has failed and crumbling sand mastic round a window, on sash and case windows, tenement windows and period & listed homes.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
A one-year guarantee comes as standard, so you’re covered after we have gone.

How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Don’t run silicone over sand mastic
- Leave the new mastic unpainted
- Go gently near the mastic when preparing windows
- Inspect the joints round the windows every year or so
Do not touch or press the mastic while it hardens. It skins over quickly but needs longer to fully harden.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall, so renewing it early is worth it.
Different surfaces, different methods
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. We renew it the same way as on windows.
Brick reveals
We rake out the old mastic and pack deep voids before pointing.
Can I do it myself?
If you’re 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.
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.

When to call us in Eddleston
Paint, silicone or cement used over old mastic causes problems. They don’t suit the joint, and they normally need raking out.
If you can see any of these, it’s time to have the joints looked at:
- Mastic that needs renewing before redecorating
- Open joints round the window box
- Old sand mastic that has cracked, crumbled or fallen out
- Cement or filler used on old window joints that has cracked
Around Eddleston, as everywhere, sand mastic is only as good as the preparation behind it.
What to look for in a quote
- When the joint can take water or movement
- Whether they’re fully insured
- What product goes in the joint
- How the joint is cleaned and prepared
How it works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. It usually takes a few hours for a single window, longer for several. Outside jobs in Eddleston need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
Preparing for the visit
- Tell us if parking is tricky
- For indoor joints, keep the area dry beforehand if you can
- Mention any leaks or damp you’ve noticed

Advice
FAQs for Eddleston
Do you cover Eddleston for sand mastic?
Yes. Our work covers the whole of Scotland, and Eddleston is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear price.
What guarantee comes with sand mastic in Eddleston?
All our work, in Eddleston and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Can you do several jobs on one visit?
Yes. Just list everything you need.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Do you work for hotels and businesses?
Yes. We can plan bigger jobs in stages to suit the site.
How do I get a quote for sand mastic in Eddleston?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before any work starts.
Leave it or put it right?
Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. In a place like Eddleston, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

What sand mastic looks like in Eddleston
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
If you live in an older home near Eddleston Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
