An t-Ollach Sand Mastic
Window and door surrounds in An t-Ollach need attention? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.

- Silicone on a period window that looks wrong
Surface by surface
Brick reveals
Gaps between frame and brick let in rain and draughts. New mastic seals the gap.
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We can do one window or several.
Sand mastic in An t-Ollach, done properly
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditional guidance is not to paint over it and we will advise if you’re redecorating. Typical jobs include cracked mastic round a front door frame and mastic that needs renewing before redecorating, on stone surrounds, timber door frames and sash and case windows.
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.
Whatever the size of the job, you get the same 12-month guarantee.

An t-Ollach questions
Does living near the coast affect sand mastic in An t-Ollach?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Can you do sand mastic in An t-Ollach?
Yes, An t-Ollach is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Do I need permission for sand mastic on a listed building?
Check with your local planning authority. They’ll tell you if consent is needed.
Which is right for my windows, sand mastic or modern sealant?
That depends on your windows. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.
Can you quote for more than one area?
Yes. More than one area can be quoted together.
Can you match the sealant colour?
Usually, yes. White, clear and grey are common, and other colours are available, and we’ll agree it with you first.
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Ask the planning authority about consent for listed or conservation-area homes
- Clear gutters so water does not pour onto the windows
- Look over the window mastic once a year
- Avoid patching sand mastic with silicone
Do not touch or press the mastic while it hardens. It skins over quickly but needs longer to fully harden.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
How it works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours per window, depending on the condition of the joints. Outside jobs in An t-Ollach 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. Work indoors is not affected.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
How to prepare
- Clear items away from the joints we’re working on
- On commercial sites, let us know about site rules
- Tell us if parking is tricky

Advice
Leave it or put it right?
Filling over old, loose mastic does not last. Raking out and preparing the joint gives it a sound base so the new work lasts. Around An t-Ollach, water from a failed joint in an older stone home can soak into timber and plaster.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

What sand mastic looks like in An t-Ollach
An t-Ollach is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
For jobs in and around An t-Ollach, choosing the right material for each joint is as important as a tidy finish.

Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you are 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 does not work out, we can still put it right.
