How we handle sand mastic in Carnbo
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. Renewing it closes the gap and tidies the surround. If you are dealing with modern sealant on a period surround and failed mastic on an exposed elevation, we can put it right, whatever the surface.
In and around a place like Carnbo, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain.
The work is covered for a year after we finish. If anything isn’t right with it, email us at info@mrmastic.co.uk.

What the job involves on each surface
Stone surrounds
Stone openings are rarely perfectly straight, so the gap isn’t the same all the way round. We shape it by hand to follow the stone.
Period and listed homes
Sand mastic is the like-for-like choice for many period homes. If your home is listed, ask your local planning authority about consent.
What happens on the day
At the end, we look at the finished work together and tell you how long to leave it. The visit itself usually takes a few hours per window, depending on the condition of the joints, depending on how much there is to do. Outside jobs in Carnbo need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Before we arrive
- Let us know about stairs, lifts or work at height
- Mention any parking rules near the property
- Clear the area around the work

How we quote for sand mastic
The quote reflects the job in front of us. We take into account:
- When we can work, for business premises
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
- Mould in or behind the old joints
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What we need to know
There’s no need for technical detail. Just tell us:
- The rough size of the job
- What the problem is, such as mould, gaps, leaks or cracking
- Access, such as stairs, a lift or height
- If it’s domestic, commercial or a hotel
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. When it suits you, drop us a line at info@mrmastic.co.uk.
Signs you need sand mastic in Carnbo
Rain on the window surround works into any crack and pushes it out. Exposed elevations usually fail first.
It’s worth asking for a quote if you see:
- Mastic worn away on windows facing the weather
- Old cement repairs round a window that have failed
- Open joints round the window box
- Mastic that needs renewing before redecorating
In and around Carnbo, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

What else we do in Carnbo
DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

Do you offer different sealant colours?

Can tenants book the work?

Why act early in Carnbo
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic suits the building and blends with the stone or brick. In an older home around Carnbo, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

Windows and doors in Carnbo
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. 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.
For jobs in and around Carnbo, choosing the right material for each joint is as important as a tidy finish.
