How we handle sand mastic in An Druim Beag
Across An Druim Beag, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand for a neat, traditional finish. If you have window mastic to renew ahead of painting and patchy fillers round a sash window, we can help, whatever the surface.
Mastic can only go onto a dry joint, so outside work in An Druim Beag depends on the weather. Tell us about access to all the windows and doors, upstairs included.
You’re 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.

Why it’s worth doing now in An Druim Beag
Draughts round a sash window aren’t always the sashes. Gaps between the frame and the wall can be just as bad and new mastic seals them. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Combining jobs into one visit normally 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.

Frames and glazing around An Druim Beag
An Druim Beag is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
For jobs in and around An Druim Beag, choosing the right material for each joint is as important as a tidy finish.

Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Sort the mastic before the decorators arrive
- Do not paint over the new mastic
- Do not run silicone over sand mastic
- Clear gutters so water doesn’t pour onto the windows
Do not run silicone over the new mastic. If you see a crack, ask us to take a look before trying a quick fix.
An open joint round the box lets weather through. Left, the gap tends to get bigger as more mastic falls out.
What affects the cost of sand mastic
For a quick quote, just ask. The main things that affect it are:
- How much old sealant there is and how hard it is to remove
- Any working-time requirements on site
- How easy the joints are to reach
- The number and length of the joints
Rather than a set price list, 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.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed 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.
Do you need sand mastic in An Druim Beag?
Over the years, sand mastic weathers. It hardens, cracks and starts to come away from the frame or the masonry.
Signs it’s time to call us include:
- Draughts and rain around sash boxes
- Mastic dropping out of the joint
- Mastic round period door frames that has failed
- Failed mastic on an exposed elevation
In and around An Druim Beag, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

An Druim Beag questions

Is it OK to seal over old sealant?

What should I tell you?

How it works
When we arrive, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. Most jobs take a few hours per window, depending on the condition of the joints. Outside jobs in An Druim Beag need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Let us know about stairs, lifts or work at height
- Try not to wet indoor joints just before the visit
- Keep children and pets away from the work area
