Sand mastic for homes and businesses in New Deer
For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. We work on stone surrounds, timber door frames and brick reveals, and common reasons people get in touch are gaps where the frame meets the masonry and failed mastic on an exposed elevation.
Mastic can only go onto a dry joint, so outside work in New Deer depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Questions from New Deer
Is sand mastic in New Deer guaranteed?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Is New Deer in your area for sand mastic?
Yes. Our work covers the whole of Scotland, and New Deer is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.
Do I need permission for sand mastic on a listed building?
Checking first is sensible. Ask your local planning authority whether consent is needed for work on a listed home or in a conservation area.
How long does sand mastic take?
As a guide, most jobs take a few hours for a single window, longer for several. Larger jobs naturally take longer, and we’ll say how long yours will take.
How long does sand mastic take to go off?
The surface skins quite quickly, then hardens over a longer period. Timing depends on the weather and the joint.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we’re using.
What affects the cost of sand mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The product the joint needs
- How many rooms, windows or areas are involved
- Whether old sealant or filler has to be cut out
- The size of the job
Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.
What we need to know
What to tell us when you ask for a quote:
- Any previous sealing or DIY work

What we can’t put right
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Whether work needs listed building consent
- Masonry that needs repairing
- Cracked or broken glass
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think before booking.

- Tenement windows
- Brick reveals
- Stone surrounds
- Period & listed homes
- Sash and case windows

Why it’s worth doing now in New Deer
Filling over old, loose mastic does not last. We remove the loose material first so the new mastic stays put. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Why book with us
- More than 20 years in sealant work
- Full insurance on every job
- ARBOMaster approved applicator
- Arbo and Everbuild products

What we’re called out for in New Deer
Decorating can disturb tired mastic. Many people find it crumbling when they prepare the windows, which is a good time to renew it.
It’s worth asking for a quote if you see:
- Gaps between timber frames and stone or brick
- Tired mastic found when preparing windows for paint
- A silicone bead on a sash window that spoils the look
- Draughts and rain around sash boxes
Around New Deer, as everywhere, sand mastic is only as good as the preparation behind it.

Frames and glazing around New Deer
Many older homes in Scotland have sash and case windows, 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 sound outside sealant is part of that.
For an older house near a landmark such as New Deer Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

The process
We work through the job in order: protect, prepare, seal, tidy. Typically it takes anything from a few hours to a full day, depending on how many windows, and the area is left clean. Outside jobs in New Deer need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Preparing for the visit
- Keep children and pets away from the work area
- Tell us about any water getting in

Keeping the joints in good condition
After the cure time, these simple habits help:
- Sort the mastic before the decorators arrive
- Get any rot dealt with first
- Take care around the mastic when scraping paint
- Look over the window mastic once a year
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at before trying a quick fix.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
