Sand mastic in Kilmore, done properly
Sand mastic does not last for ever, leaving gaps round the window. Renewing it closes the gap and tidies the surround. Typical jobs include crumbling sand mastic round a window and gaps where the frame meets the masonry, across stone surrounds, timber door frames and brick reveals.
Outdoor sealant needs a dry surface, so window work around Kilmore is planned around the weather. Tell us about access to all the windows and doors, upstairs included.
You’re covered for a year from the day we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

Aftercare tips
A little care helps the new joints last. Our advice:
- Leave the new mastic unpainted
- Renew mastic before redecorating the windows
- Inspect the joints round the windows every year or so
- Take care around the mastic when scraping paint
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry so early renewal protects both.
Leave it or put it right?
New mastic over crumbling mastic will not hold. Raking out and preparing the joint gives it a sound base so the new work lasts. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.

Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

The process
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to a full day, depending on how many windows. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- 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
- Let us know about stairs, lifts or work at height
- For indoor joints, keep the area dry beforehand if you can
- Let us know about earlier repairs to the joints

Advice
What affects the cost of sand mastic
The price is agreed before any work begins. It’s based on:
- How many rooms, windows or areas are involved
- How much old sealant there is and how hard it is to remove
- Working hours on commercial sites
- The number and length of the joints
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and give you a clear price before any work starts.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- The rough size of the job
- Pictures of the joints, sent by email
- If someone has resealed it before
Every job is quoted individually, so the first step is telling us about yours. Just email us at info@mrmastic.co.uk with the details and send pictures if you have them.
Kilmore: your questions answered
Do you work for landlords with property near Oban station?
Yes, landlords and agents are among the people we work for. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear price.
Will you come out to Kilmore?
Yes. Kilmore is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Can you match the sealant colour?
Usually, yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before work begins.
Is consent needed for window work on a listed home?
Yes, it’s worth checking. Ask your local planning authority whether consent is needed for work on a listed home or in a conservation area.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Do you guarantee sand mastic work?
Every job comes with our one-year guarantee.

Frames and glazing around Kilmore
Kilmore is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. The west of Scotland is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out.
Rented homes near Oban station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. If you look after a building such as Oban High School, its window and door frames need their mastic kept sound, just like a home’s. In the older streets around Kilmore Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
