Colliston Sand Mastic
We cover Colliston for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Mastic dropping out of the joint
- Mastic worn away on windows facing the weather
- Cracked mastic round a front door frame
How we handle sand mastic in Colliston
A silicone bead around a sash window can look out of place and doesn’t suit the building. Sand mastic is the traditional choice and we can swap the silicone for it. We work on sash and case windows, timber door frames and tenement windows, and the jobs we see most are gaps where the frame meets the masonry and crumbling sand mastic round a window.
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.
You are covered for a year from the day we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

How the job changes by surface
Tenement and terrace windows
Rows of sash windows on tenements and terraces often need renewing together. We can do one window or several.
Stone surrounds
The stone is treated with care while raking out the old mastic.
How we quote for sand mastic
The price is agreed before any work begins. It’s based on:
- Which sealant suits the joint
- Whether there’s mould to deal with
- The size of the job
- How many rooms, windows or areas are involved
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. We will send you a clear quote for the lot.
Helping us quote
To help us quote quickly, let us know:
- If someone has resealed it before
- The type of property
- What’s wrong with the joints now
- Pictures of the joints, sent by email
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we will talk you through the work and give you a clear price.
Why it’s worth doing now in Colliston
New mastic over crumbling mastic will not hold. We remove the loose material first so the new work lasts. In an older home around Colliston, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we will explain what it covers.

Advice
Colliston: your questions answered
Do you work for landlords with property near Arbroath station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
Is Colliston within the area you cover?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we’re done.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Frames and glazing around Colliston
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
In and around Colliston, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint. Letting a property close to Arbroath station? Then any sash windows need sound mastic to keep draughts and rain out.

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Do not run silicone over sand mastic
- Ask a joiner to look at soft timber first
- Ask us before painting near the mastic
- Avoid heavy scraping on the mastic joint
Leave the new mastic unpainted, as traditional guidance advises. Ask us before any decorating around it.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Crumbling stone or brickwork round the window
- Broken panes
- Rotten sashes, sills or window boxes (a joiner’s job)
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.
