Sand mastic for sash & case windows in Spittal, Dumfries and Galloway
We cover Spittal for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old sealant removed completely, joints prepared properly.
- A silicone bead on a sash window that spoils the look
- Mastic dropping out of the joint
- Gaps round a timber door in stone or brick
What happens on the day
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a few hours for a single window, longer for several, including the tidy-up. Somewhere like Spittal may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- 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.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Keep pets and children clear of the area while we work
- Clear items away from the joints we’re working on

Related advice
Sand mastic for homes and businesses in Spittal
Sand mastic suits most period window surrounds. Newer frames normally get a flexible sealant instead, and we will talk through which suits your home. If you are dealing with silicone on a period window that looks wrong and cracked mastic round a front door frame, we can put it right, whatever the surface.
In and around a place like Spittal, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
The work is covered for a year after we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

What else we do in Spittal
Leave it or put it right?
Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic matches what was there and that can be important for listed homes. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Why us?
- Anti-fungal silicone where joints get wet
- Tidy, careful work
- We’re fully insured
- Quality sealants from Arbo and Everbuild

Questions from Spittal
Can you do sand mastic in Spittal?
Yes. Our work covers the whole of Scotland, and Spittal is part of that. Just email us at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear quote.
Is sand mastic in Spittal guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Should I use sand mastic or silicone?
It depends on the window. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.
Can you replace silicone on a period window with sand mastic?
Generally, yes. Once the silicone is out and the joint prepared we point it with sand mastic.
What does sand mastic cost?
Every job is different, so each one gets its own quote. For a quick quote, email us at info@mrmastic.co.uk with a short description of the job.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Can I choose the sealant colour?
We will suggest a colour to suit the surroundings. The choice depends on the product the joint needs.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
Signs you need sand mastic in Spittal
Age is the main cause. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
These are the problems we’re asked about most:
- Window mastic to renew ahead of painting
- Gaps round a timber door in stone or brick
- Cement or filler used on old window joints that has cracked
- Wind and rain getting in round a sash window
Around Spittal, as everywhere, sand mastic is only as good as the preparation behind it.
Questions to ask before booking
- Whether all the old sealant comes out first
- How long to leave it before use
- Who turns up on the day
- Are they insured?
What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Decayed frames that need repair
- Sashes that need overhauling
- Decisions on consent for listed homes
If in doubt, email us at info@mrmastic.co.uk and we will say what we think before you book.

Aftercare tips
To keep the joints looking good and working properly:
- Make sure water runs off the sill
- Don’t run silicone over sand mastic
- Go gently near the mastic when preparing windows
- Sort the mastic before the decorators arrive
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.
Sand mastic in Spittal: local notes
The west of Scotland is wetter than the east, which means the mastic around older windows and doors has to cope with a lot of rain. With historic houses such as Craighlaw (about 4 miles north-west) nearby, there’s older building stock in the area around Spittal as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Craighlaw, about 4 miles north-west, is one of the historic houses in the wider area around Spittal.
