Sand mastic for sash & case windows in Cottown, Aberdeenshire
Window and door surrounds in Cottown need attention? We remove the old material, prepare the joints and seal them properly.
- Modern sealant on a period surround
- Open joints round the window box
- Old sand mastic that has cracked, crumbled or fallen out
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
About our sand mastic in Cottown
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant and we will explain which is best for yours. Typical jobs include draughts and rain around sash boxes and patchy fillers round a sash window, across brick reveals, timber door frames and sash and case windows.
Outdoor sealant needs a dry surface, so window work around Cottown is planned around the weather. Tell us about access to all the windows and doors, upstairs included.
Your job is guaranteed for a year, as with all our work.

Common questions in Cottown
Can you help a landlord with a rental near Kintore station?
Yes, we work for letting agents and landlords. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we will send you a clear quote.
Is Cottown within the area you cover?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Do the sealants smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
Where do you work from?
We work from Crawley. We cover Cottown and the rest of Aberdeenshire.
What’s sand mastic made of?
It’s sand mixed with a linseed-oil-based binder, used between timber frames and stone or brick.
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 listed or conservation-area properties.
How it works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a single window, longer for several. Outside jobs in Cottown need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work

What sand mastic looks like in Cottown
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Rented homes near Kintore station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

Quotes for sand mastic in Cottown
You will get a clear quote before we start. It’s based on:
- The product the joint needs
- Working hours on commercial sites
- How many rooms, windows or areas are involved
- The old material and how stubborn it is
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- Roughly how big the job is
- Photos by email, if that’s easy
- Where the property is
- What the problem is, such as mould, gaps, leaks or cracking
We quote each job on its own, so start by telling us what you need. Just email us at info@mrmastic.co.uk with the details.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Ask the planning authority about consent for listed or conservation-area homes
- Renew mastic before redecorating the windows
- Have rotten timber repaired before new mastic goes in
- Do not paint over the new mastic
Don’t touch or press the mastic while it hardens. It skins over quickly, but takes longer to harden fully.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens as more mastic falls out.
