Sand mastic in Symington, done properly
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. The old mastic is raked out, and new mastic is applied and shaped by hand. If you have patchy fillers round a sash window and wind and rain getting in round a sash window, we can help, on stone surrounds, tenement windows and timber door frames alike.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
Every job is covered by our 12-month guarantee.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Your questions about sand mastic in Symington
Do you cover smaller places like Symington?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Prestwick International Airport station. Can you help?
Yes. We work for landlords and agents as well as homeowners. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear quote.
When will the new mastic be hard?
It forms a skin fairly soon and it hardens fully over a longer time. Timing depends on the weather and the joint.
Can sand mastic be painted?
Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we will advise.
Which products do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
How long does the job take?
A typical job takes a few hours for a single window, longer for several. We will confirm how long when we quote.
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.
Will there be a smell?
Possibly a little. It fades as the sealant cures.
What sand mastic looks like in Symington
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. Symington is in the west of Scotland, which is wetter than the east, which means the mastic around older windows and doors has to cope with a lot of rain.
For an older house near a landmark such as Symington Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

For landlords and businesses
Landlords and agents in Symington can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
The process
We keep the work tidy and contained to the area we are working on, so you can carry on as normal. Expect the work to take a few hours for a single window, longer for several, and we explain the cure time before we leave. Outdoor work around Symington depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- 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.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
Before we arrive
- Tell us about any water getting in
- On commercial sites, let us know about site rules
- Tell us about any previous sealing or DIY attempts

Advice
What sealant work can’t fix
It helps to know what we cannot do too:
- Sashes that need overhauling
- Planning or listed building consent (your local planning authority decides)
- Damaged stone surrounds
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think before booking.
What we seal
- Tenement windows
- Brick reveals
- Timber door frames
- Period & listed homes

How we quote for sand mastic
The quote reflects the job in front of us. We look at:
- The product the joint needs
- The old material and how stubborn it is
- The number and length of the joints
- Any mould that needs treating
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- A few pictures by email, if you can
- If it’s domestic, commercial or a hotel
- How many joints, rooms or windows are involved
- If someone has resealed it before
Every job is quoted individually, so start by telling us what you need. Simply send an email to info@mrmastic.co.uk and describe the job.
Why deal with it now?
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic will not stop the gaps, and the new mastic is traditionally left unpainted. In a place like Symington, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.
Why us?
- Any old sealant cut out fully, not covered over
- 20+ years of sealant experience
- ARBOMaster approved applicator
- Domestic, commercial and hotel work
