Sand mastic in Kilcreggan
Silicone on a period window often looks wrong and does not suit the building. Sand mastic is the traditional choice and we can swap the silicone for it. If you are dealing with cement or filler used on old window joints that has cracked and a silicone bead on a sash window that spoils the look, we can put it right.
Outdoor sealant needs a dry surface, so window work around Kilcreggan is planned around the weather. Tell us about access to all the windows and doors, upstairs included.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can be quoted together.
Landlords and letting agents in Kilcreggan can book us as well as householders. Sealant work between tenants keeps a property looking cared for.
Leave it or put it right?
An open joint round the frame lets weather in. Left, water can reach the timber and the wall, so dealing with it now protects both. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Combining jobs into one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

Frames and glazing around Kilcreggan
Kilcreggan is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
If you live in an older home near Craigrownie Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Gourock station, older sash windows in a rental need their mastic kept sound to keep the weather out. Schools such as Gourock High School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
If you do try it yourself, take your time over the 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.
How it works
When we arrive, we start by going over the job with you, so you know exactly what we are doing. Surfaces next to the work are protected before work begins. The work normally takes a few hours for a single window, longer for several. Around Kilcreggan, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- 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.
How to prepare
- Clear items away from the joints we’re working on
- Keep children and pets away from the work area
- Where the joints are inside, avoid wetting them before we arrive

Common questions in Kilcreggan
Does the coastal weather in Kilcreggan affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
Do you cover smaller places like Kilcreggan?
Yes, we do. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
How long does sand mastic take?
It depends on the size of the job, but as a guide it takes a few hours per window, depending on the condition of the joints. We’ll give you a better idea when we quote.
Can new sealant go over the old?
No. The old sealant always comes out first.
What do you put in the joint?
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.
Is it possible to paint over sand mastic?
It’s traditionally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near 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 photos.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done.

Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Check the mastic when you check the paintwork
- Avoid heavy scraping on the mastic joint
- Ask a joiner to look at soft timber first
- Find out about consent before window work on a listed home
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
An open joint round the box lets weather through. Left, the gap tends to get bigger.
