Sand mastic in Oakbank, done properly
Across Oakbank, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand, finished to suit the masonry. If you have gaps round a timber door in stone or brick and a silicone bead on a sash window that spoils the look, we can help.
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.
There’s a 12-month guarantee on every job, whatever its size.

FAQs for Oakbank
Do you cover Oakbank for sand mastic?
Yes. Our work covers the whole of Scotland, and Oakbank is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing, and we will send you a clear quote.
I let a flat near Perth station. Can you help?
Yes, landlords and agents are among the people we work for. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
How long does sand mastic take to go off?
Not straight away. The skin forms first, and the full set comes later and we’ll give you an idea for your job.
Is it OK to seal over old sealant?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Honest limits
It helps to know what we cannot do too:
- Cracked or broken glass
- Masonry that needs repairing
- Rotten sashes, sills or window boxes (a joiner’s job)
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer.

What affects the cost of sand mastic
We quote each job individually. This is what makes a difference:
- Any working-time requirements on site
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
- The product the joint needs
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts.
Asking for a quote
Photos by email are helpful but not essential. Try to tell us:
- The type of property
- The rough size of the job
- What the problem is, such as mould, gaps, leaks or cracking
- How we’d reach the joints
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we’ll talk you through the work and give you a clear price.
Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
For anyone letting property in or around Oakbank, several properties can go on one quote. Send us the addresses and the work at each.
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 Oakbank, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, email us at info@mrmastic.co.uk for an honest opinion and a quote.

Oakbank homes and the weather
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
Schools such as Perth High School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Perth station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Can I do it myself?
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.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Aftercare tips
A little care helps the new joints last. We recommend:
- Leave the new mastic unpainted
- Check the mastic when you check the paintwork
- Find out about consent before window work on a listed home
- Keep modern sealant off the mastic
Leave the new mastic alone while it firms up. It forms a skin fairly soon but needs longer to fully harden.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
The process
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to a full day, depending on how many windows. Outdoor work around Oakbank depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Let us know about stairs, lifts or work at height
- Try not to wet indoor joints just before the visit
