Sand mastic in Crawford
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. We work on sash and case windows, stone surrounds and timber door frames, and common reasons people get in touch are mastic worn away on windows facing the weather and tired mastic found when preparing windows for paint.
In and around a place like Crawford, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Looking after it afterwards
Looking after new joints is easy:
- Check with your local planning authority if your home is listed
- Ask a joiner to look at soft timber first
- Sort the mastic before the decorators arrive
- Avoid patching sand mastic with silicone
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
Frames and glazing around Crawford
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. 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.
Around Crawford, as everywhere, sand mastic is only as good as the preparation behind it. Homes close to Parish Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Crawford is about 20 miles south of Carluke, in South Lanarkshire. Whether you are in the middle of Crawford or further out, sand mastic is available for homes and businesses alike.

Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The process
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes a few hours per window, depending on the condition of the joints for a typical job. Outside jobs in Crawford need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- Mention any leaks or damp you’ve noticed
- Move anything stored near the joints
- Tell us if parking is tricky

Is consent needed for window work on a listed home?
Check with your local planning authority. They decide whether consent is needed.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.

Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Surface by surface
Stone surrounds
The stone is treated with care while raking out the old mastic.
Timber door frames
Doors face weather and wear, so their mastic can fail sooner. It’s renewed by hand.
How we quote for sand mastic
The price is agreed before any work begins. It takes into account:
- Whether the work is at height
- Whether old sealant or filler has to be cut out
- The type of sealant required
- When we can work, for business premises
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Helping us quote
Before you ask for a quote, have a think about:
- The rough size of the job
- Pictures of the joints, sent by email
- What the problem is, such as mould, gaps, leaks or cracking
- Any access issues, like height or stairs
We do not publish a price list. Instead, your job gets its own clear quote. To get started, send an email to info@mrmastic.co.uk.
