How to look after the new joints
To keep the joints looking good and working properly:
- Check the mastic when you check the paintwork
- Avoid heavy scraping on the mastic joint
- Don’t paint over the new mastic
- Avoid patching sand mastic with silicone
Do not run silicone over the new mastic. If you see a crack, ask us to take a look before trying a quick fix.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
Sand mastic for homes and businesses in Elsrickle
Sand mastic skins over fairly quickly but full hardening takes longer. Traditional guidance is not to paint over it and we will advise if you are redecorating. If you have mastic worn away on windows facing the weather and open joints round the window box, we can help.
Outdoor sealant needs a dry surface, so window work around Elsrickle is planned around the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
We stand behind the work with a one-year guarantee, so you are covered after we have gone.

Elsrickle homes and the weather
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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Whether the job is in Elsrickle itself or nearby, the right material for each joint matters as much as a neat finish. Around Elsrickle, as everywhere, sand mastic is only as good as the preparation behind it.

Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Questions from Elsrickle
Do you cover Elsrickle for sand mastic?
Yes, Elsrickle is within the area we cover. Our work covers the whole of Scotland. You can email us at info@mrmastic.co.uk and let us know what needs doing, and we’ll give you a clear price.
What guarantee comes with sand mastic in Elsrickle?
All our work, in Elsrickle and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
What exactly is sand mastic?
Sand plus a binder based on linseed oil. It’s built up in the joint by hand and shaped to suit the surround.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
Should I use sand mastic or silicone?
We’ll help you decide. Period homes often look best with sand mastic, and modern sealants suit newer frames.
Where is Mr Mastic based?
We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
How long does sand mastic take to harden?
It takes a while. It skins first and hardens fully later, and we’ll tell you what to expect.
What the job involves on each surface
Sash and case windows
Most of our sand mastic work is on sash windows. Each joint round the box is raked out and renewed.
Timber door frames
Round a period front door, sand mastic gives the right look.
Leave it or put it right?
If you are redecorating, renew the mastic first. Paint over cracked mastic will not stop the gaps and traditional guidance is to leave the new mastic unpainted. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why us?
- Domestic, commercial and hotel work
- Every job guaranteed for a year
- We leave the area clean and tidy
- Anti-fungal sanitary silicone in wet areas

For landlords and businesses
Housing providers, facilities teams and property managers book us too. Several sites can go on one quote, and we are fully insured for the work.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

How the visit works
The work is kept neat and contained to the joints we are treating. The job normally takes a few hours per window, depending on the condition of the joints, and we tell you how long to leave it before we go. Outside jobs in Elsrickle need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We look at the surrounds with you and agree the joints to renew.
- 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
- Mention any sign-in or site rules at work premises
- Clear the area around the work
- Keep children and pets away from the work area
