Sand mastic across Cottown and nearby, with old sealant always removed completely.
- Draughty sash windows at the surround

Work for landlords, hotels and businesses
We work for landlords and letting agents as well as homeowners. Resealing between tenancies keeps a property looking cared for.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
How we handle sand mastic in Cottown
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It suits period and listed homes where a modern sealant bead would stand out. If you’re dealing with mastic dropping out of the joint and wind and rain getting in round a sash window, we can put it right.
Outdoor sealant needs a dry surface, so window work around Cottown is planned around the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

How the visit works
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the job takes a few hours per window, depending on the condition of the joints for a typical job. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Getting ready for the visit

- Keep pets and children clear of the area while we work

Leave it or put it right?
Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. In an older home around Cottown, damp from a failed joint can get into timber and plaster.
The cost depends on how much there is to do, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.

Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Look over the window mastic once a year
- Take care around the mastic when scraping paint
- Don’t paint over the new mastic
- Have rotten timber repaired before new mastic goes in
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
Different surfaces, different methods
Stone surrounds
We take care not to mark the stone when the old mastic comes out.
Timber door frames
Round a period front door, sand mastic gives the right look.
Should I try it myself first?
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 fails, we can still redo it.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Cottown homes and the weather
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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
