Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Sand mastic in Ardrossan, done properly
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder and built up by hand. On older homes, it suits the building far better than silicone. We work on tenement windows, timber door frames and brick reveals, and the jobs we see most are old sand mastic that has cracked, crumbled or fallen out and open joints round the window box.
In and around a place like Ardrossan, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
There’s a 12-month guarantee on every job.

Leave it or put it right?
Not every filler suits an old window surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. In a place like Ardrossan, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.

Frames and glazing around Ardrossan
Ardrossan is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Ardrossan is in the west of Scotland, which is wetter than the east, which means the mastic around older windows and doors has to cope with a lot of rain.

Your questions about sand mastic in Ardrossan
Is sand mastic in a coastal place like Ardrossan any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Will you come out to Ardrossan?
Yes, we do. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Is sand mastic better than silicone for my windows?
It depends on the window. Period windows in stone or brick generally suit sand mastic, while modern frames normally get a flexible sealant.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do you guarantee sand mastic work?
You get our one-year guarantee to all our work.
What should I tell you?
Tell us what needs doing and where, plus photos if you have them. We will ask anything else we need to know.
How much does sand mastic cost in Ardrossan?
Every job is different, so each one gets its own quote. For a quick quote, email us at info@mrmastic.co.uk and tell us what needs doing and where.
Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
What affects the cost of sand mastic
For a quick quote, just ask. The main things that affect it are:
- Any mould that needs treating
- The old material and how stubborn it is
- The size of the job
- The number of rooms or windows
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Asking for a quote
There’s no need for technical detail. Just tell us:
- What’s wrong with the joints now
- Any previous sealing or DIY work
- A few photos by email, if you can
- Whether it’s a home or a business

Signs you need sand mastic in Ardrossan
Some old mastic was never deep enough. Mastic that’s too thin cracks and drops out so we make sure the new mastic is the right thickness.
Most people get in touch when they notice something like this:
- Mastic that needs renewing before redecorating
- Failed mastic on an exposed elevation
- Mastic dropping out of the joint
- Gaps round a timber door in stone or brick
Schools such as Ardrossan Academy are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
What to look for in a quote
- Is the old sealant removed completely?
- Is VAT in the price?
- When the joint can take water or movement
- What insurance they hold

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
What the job involves on each surface
Brick reveals
Gaps between frame and brick let in rain and draughts. New mastic seals the gap.
Sash and case windows
A sash window’s box frame sits in the masonry opening. The gap round it is pointed with sand mastic.
What happens on the day
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes a few hours per window, depending on the condition of the joints from start to finish. Outdoor work around Ardrossan depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
