- Gaps where the frame meets the masonry
- Mastic round period door frames that has failed
- Mastic that needs renewing before redecorating
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Check the mastic when you check the paintwork
- Clear gutters so water doesn’t pour onto the windows
- Don’t paint over the new mastic
- Ask a joiner to look at soft timber first
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
About our sand mastic in Kilmory
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. Renewing it closes the gap and tidies the surround. Typical jobs include gaps round a timber door in stone or brick and a silicone bead on a sash window that spoils the look, across tenement windows, stone surrounds and sash and case windows.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
Each job carries a 12-month guarantee, large or small.

What we can’t put right

Why it’s worth doing now in Kilmory
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall so renewing it early protects the window. Around Kilmory, water from a failed joint in an older stone home can soak into timber and plaster.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

Windows and doors in Kilmory
Kilmory is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Around Kilmory, as everywhere, sand mastic is only as good as the preparation behind it.

Questions from Kilmory
Will you come out to Kilmory?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you cover Kilmory for sand mastic?
Yes, Kilmory is within the area we cover. We work across all of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job, and we will send you a clear quote.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Do you work for hotels and businesses?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
How long does sand mastic take to harden?
It forms a skin fairly soon and it hardens fully over a longer time. Timing depends on the weather and the joint.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Kilmory, along with the rest of our area.
Can I choose the sealant colour?
Generally, yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before any work starts.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
How the job changes by surface
Brick reveals
We rake out the old mastic and pack deep voids before the new mastic goes in.
Sash and case windows
A sash window’s box frame sits in the masonry opening. The gap round it is pointed with sand mastic.
The process
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and clear up. It generally takes a few hours per window, depending on the condition of the joints. For a place like Kilmory, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Let us know about parking restrictions
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Do you need sand mastic in Kilmory?
Previous repairs in cement or silicone often trap water or crack away. They do not move with the timber, and they normally need raking out.
Any of these means the joints need attention:
- Mastic worn away on windows facing the weather
- Gaps where the frame meets the masonry
- Silicone on a period window that looks wrong
- Mastic round period door frames that has failed
Homes close to Kilmory Parish Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
