Sand mastic for homes and businesses in Westmuir
Sand mastic suits most period window surrounds. Newer frames generally get a flexible sealant instead and we’ll explain which is best for yours. If you have mastic dropping out of the joint and cement or filler used on old window joints that has cracked, we can help, on tenement windows, stone surrounds and period & listed homes alike.
In and around a place like Westmuir, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
Whatever the size of the job, it’s backed by our one-year guarantee.

Different surfaces, different methods
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.
Stone surrounds
Stone openings are rarely perfectly straight, so the joint varies in width. We shape it by hand to follow the stone.

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Quotes for sand mastic in Westmuir
Some jobs are bigger than they look, and some smaller. The main factors:
- Whether the work is at height
- Whether old sealant or filler has to be cut out
- Which sealant suits the joint
- The number and length of the joints
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

The process
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to a full day, depending on how many windows. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- Clear the area around the work
- Let us know about stairs, lifts or work at height
- Tell us about any water getting in

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Get any rot dealt with first
- Inspect the joints round the windows every year or so
- Take care around the mastic when scraping paint
- Find out about consent before window work on a listed home
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens.
Windows and doors in Westmuir
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.

What exactly is sand mastic?
Sand mastic is a traditional material for pointing round windows and doors. It’s made with sand and a linseed-oil-based binder.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Why act early in Westmuir
Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
What you pay reflects the work, not guesswork. That is why we ask a few questions first.
