Sand mastic in Ardbrecknish, done properly
Silicone on a period window often looks wrong and does not suit the building. Sand mastic is the traditional choice, and we can replace one with the other. We work on brick reveals, tenement windows and sash and case windows, and people most often call us about cement or filler used on old window joints that has cracked and gaps between timber frames and stone or brick.
Mastic can only go onto a dry joint, so outside work in Ardbrecknish depends on the weather. Let us know about access to every frame, including any upstairs.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Quotes for sand mastic in Ardbrecknish
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The size of the job
- The type of sealant required
- The old material and how stubborn it is
- How many rooms, windows or areas are involved
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
What we need to know
Before you ask for a quote, have a think about:
- A few pictures by email, if you can
- Access, such as stairs, a lift or height
- Roughly how big the job is
- If someone has resealed it before
There’s no standard price list, as no two jobs are quite the same. Instead, we give you a clear quote for your job. To get started, drop us a line at info@mrmastic.co.uk.
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Some sealant jobs are within reach of a careful DIYer, 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.
How it works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. It generally takes a few hours per window, depending on the condition of the joints. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- 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.
- Large voids are packed out first, so the mastic is not too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property
- Keep children and pets away from the work area

Related advice
Looking after it afterwards
A little care helps the new joints last. Our advice:
- Clear gutters so water does not pour onto the windows
- Ask a joiner to look at soft timber first
- Do not run silicone over sand mastic
- Find out about consent before window work on a listed home
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry so early renewal protects both.
Why deal with it now?
Filling over old, loose mastic does not last. Raking out and preparing the joint gives it a sound base so the new mastic stays put. In an older home around Ardbrecknish, damp from a failed joint can get into timber and plaster.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.

Ardbrecknish homes and the weather
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. 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.
If you let a flat or house near Falls of Cruachan station, older sash windows in a rental need their mastic kept sound to keep the weather out. In and around Ardbrecknish, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.
