What sand mastic looks like in Crookston
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. With historic houses such as Pollok House (about 2.2 miles south-east) nearby, there’s older building stock in the area around Crookston as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Pollok House, about 2.2 miles south-east, is one of the historic houses in the wider area around Crookston, and older homes nearby need a sealant that suits their walls. If you look after a building such as Rosshall Academy, the mastic around its windows and doors needs looking after like any other building’s.

Sand mastic in Crookston, done properly
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. Typical jobs include modern sealant on a period surround and old sand mastic that has cracked, crumbled or fallen out, across period & listed homes, tenement windows and timber door frames.
Older stone-built tenements in Scotland’s cities were built with sash and case windows, and plenty still have them. Whether you’re in a tenement flat or a house in Crookston, the joint between frame and wall is what keeps the weather out.
All of our work is guaranteed for twelve months, in Crookston and everywhere else we cover.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
For landlords and businesses

How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours per window, depending on the condition of the joints and we leave things clean and tidy. For a tenement in Crookston, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. It helps to know which it is when you get in touch.
- 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.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Keep pets and children clear of the area while we work
- Clear items away from the joints we are working on

Paint, silicone or cement used over old mastic causes problems. They don’t move with the timber, and they normally need raking out.
Most people get in touch after spotting something like this:
- A silicone bead on a sash window that spoils the look
- Cracked mastic round a front door frame
- Crumbling sand mastic round a window
- Wind and rain getting in round a sash window
For landlords with property near Crookston station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Leave it or put it right?
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. Wind-driven rain gets into any failed joint on the outside of a city building, and in Crookston, damp can spread through stone and plaster before anyone sees it.
