How we handle sand mastic in Clachan of Campsie
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. We work on tenement windows, stone surrounds and period & listed homes, and common reasons people get in touch are silicone on a period window that looks wrong and weathered mastic on the most exposed windows.
Outdoor sealant needs a dry surface, so window work around Clachan of Campsie is planned around the weather. Let us know about access to every frame, including any upstairs.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

Do you need sand mastic in Clachan of Campsie?
Paint, silicone or cement used over old mastic causes problems. They do not suit the joint and we normally remove them.
The problems people usually mention when they call are:
- Mastic dropping out of the joint
- Modern sealant on a period surround
- Wind and rain getting in round a sash window
- Tired mastic found when preparing windows for paint
Rented homes near Milngavie station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.
Before you book anyone
- What preparation is included
- Whether VAT is included
- What product goes in the joint
- When the joint can take water or movement
When something else is needed
New sealant can’t fix everything, and we’d rather say so up front. It won’t solve:
- Crumbling stone or brickwork round the window
- Sash cords, weights and draught-proofing of the sashes
- Putty and glazing repairs

Why deal with it now?
Before painting the windows, it pays to renew the mastic. Painting over failed mastic does not seal it and traditional guidance is to leave the new mastic unpainted. 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.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

Clachan of Campsie questions
Is Clachan of Campsie in your area for sand mastic?
Yes, Clachan of Campsie is within the area we cover. Our work covers the whole of Scotland. You can email us at info@mrmastic.co.uk and let us know what needs doing.
I let a flat near Milngavie station. Can you help?
Yes, rental work is part of what we do. You can email us at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before work begins.
Do the sealants smell?
Possibly a little. It fades as the sealant cures.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and you will get one quote.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
How long does sand mastic take to harden?
The surface skins quite quickly and it hardens fully over a longer time. Timing depends on the weather and the joint.
What do you need from me for a quote?
A short description and the location. We will ask anything else we need to know.
How it works
Before we leave, we go over the finished joints with you. The visit itself generally takes a few hours for a single window, longer for several, depending on the size of the job. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any previous sealing or DIY attempts
- Mention any parking rules near the property

Windows and doors in Clachan of Campsie
Clachan of Campsie 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. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
In the older streets around St Machan's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Tenements and terraces often have many sash windows with ageing mastic. We work on single windows or whole elevations.

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Clear gutters so water doesn’t pour onto the windows
- Ask the planning authority about consent for listed or conservation-area homes
- Do not run silicone over sand mastic
- Check the mastic when you check the paintwork
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look rather than patching it.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens as more mastic falls out.
