How we handle window mastic in Slackbuie
Some gaps around frames are far deeper than they look. Packing it solid with sealant gives a joint that can’t flex, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. If you are dealing with damp patches on the reveal after heavy rain and black, perished sealant on frames, we can put it right.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
You are covered for a year from the day we finish. If anything is not right with it, email us at info@mrmastic.co.uk.

Windows and doors in Slackbuie
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
If you let a flat or house near Inverness station, renewing tired window mastic between tenants heads off draught and damp complaints.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Questions from Slackbuie
Will you come out to Slackbuie?
Yes. Slackbuie is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Can you do window mastic in Slackbuie?
Yes. Our work covers the whole of Scotland, and Slackbuie is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will give you a clear price.
When is the sealant fully cured?
It depends on the product and the conditions. Before we leave, we’ll tell you the cure time.
How long does it take to reseal the windows on a house?
It depends on access, the old mastic and the size of the frames. We’ll tell you how long your job needs when we quote.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Do you work for landlords and businesses?
Yes, we do. We work in homes, commercial premises and hotels, and we are fully insured.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
How we quote for window mastic
We quote each job individually. This is what makes a difference:
- Which sealant suits the joint
- The number of rooms or windows
- The old material and how stubborn it is
- Whether the work is at height
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please send an email to info@mrmastic.co.uk.
Helping us quote
To help us quote quickly, please include:
- Any previous sealing or DIY work
- What’s wrong with the joints now
- If it’s domestic, commercial or a hotel
- Access, such as stairs, a lift or height
To get a quote, drop us a line at info@mrmastic.co.uk with the location and a short description of the problem. We will send you a clear quote before any work starts.
How to look after the new joints
After the cure time, these simple habits help:
- Wash the frames with mild soapy water
- Look round the frames every year or so
- Avoid harsh chemicals near the mastic
- Ventilate rooms so frames don’t stay wet inside
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak, and if anything looks wrong, just send an email to info@mrmastic.co.uk.
Leaks generally show up in wet, windy weather, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
Why deal with it now?
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. 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.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, email us at info@mrmastic.co.uk for an honest opinion and a quote.

What we do, step by step
We bring everything the job needs with us, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take a morning for a couple of windows and a door. Outside jobs in Slackbuie need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We start by checking each window and door with you.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
Getting ready for the visit
- On commercial sites, let us know about site rules
- For indoor joints, keep the area dry beforehand if you can
- Mention if the joints have been sealed before

When to call us in Slackbuie
Some failures date back to when the windows were fitted. Sealant run over dust, wet brick or loose mortar never bonded as it should, and it lets go sooner than it should.
These are the problems we are asked about most:
- Gaps between the frame and the inside reveal
- Untidy mastic left by window fitters
- Water coming in at the bottom corners of a door
- Sealant in the wrong colour for the frame
In and around Slackbuie, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
