- Draughty sash windows at the surround
The process
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes anything from a few hours to a full day, depending on how many windows. For a place like Montgomerieston, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- Deep voids are packed so the mastic is the right thickness.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Clear items away from the joints we’re working on
- Let us know if you’ve seen damp or leaks
- Plan for the work area to be out of bounds to pets and children

Sand mastic in Montgomerieston
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant and we’ll explain which is best for yours. If you have mastic that needs renewing before redecorating and failed mastic on an exposed elevation, we can put it right, on stone surrounds, timber door frames and sash and case windows alike.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
There’s a 12-month guarantee on every job, whatever its size.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Go gently near the mastic when preparing windows
- Find out about consent before window work on a listed home
- Sort the mastic before the decorators arrive
- Get any rot dealt with first
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.

Every job gets its own quote. This is what makes a difference:
- Any mould that needs treating

What we are called out for in Montgomerieston
Water gets into small cracks in the mastic and loosens it further. Exposed elevations normally fail first.
These are the problems we’re asked about most:
- Cracked mastic round a front door frame
- Mastic dropping out of the joint
- Tired mastic found when preparing windows for paint
- A silicone bead on a sash window that spoils the look
Rented homes near Ayr station change hands often, and any sash windows need sound mastic to keep draughts and rain out.
What your quote should include
- Whether the sealant suits the joint
- Whether all the old sealant comes out first
- Which colour the sealant will be
- What insurance they hold
Montgomerieston homes and the weather
Montgomerieston is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. 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.
Homes close to St John The Baptist's Church include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in. Managing a site like Ayr Academy? Then the mastic around its windows and doors needs looking after like any other building’s.

Your questions about sand mastic in Montgomerieston
Will you come out to Montgomerieston?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Can you help a landlord with a rental near Ayr station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Can old silicone round a sash window be swapped for sand mastic?
Yes, it’s a common request. All the old silicone is removed first so the mastic beds in well.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and we will quote it together.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
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.
