About our new build mastic in Glenmavis
Snagging sealant properly means taking the failed bead out completely. New silicone will not bond to old silicone, so it all comes out before we clean, dry and reseal. Common call-outs are for skirting joints opening in the first winter and internal frame sealant that has split, across plot handovers, show homes and windows & doors.
Timber frame is common in newer Scottish homes, and it settles over the first years, which shows as gaps at skirtings and floor joints. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Check bath and shower seals every few months as the house settles
- Clean sealant with mild detergent, not abrasives
- Act quickly if a seal starts to leak
- Follow the cure time we give you
Do not stand on the bath edge or the lip of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.

Other services in Glenmavis
Work for landlords, hotels and businesses
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
What we’re called out for in Glenmavis
On many sites, sealant goes on in the final rush before handover. Joints are not always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
The problems people usually mention when they call are:
- Sealant work across a run of new homes
- Skirting joints opening in the first winter
- Messy sealant that spoils new finishes
- Sealant that never bonded to the surface
In and around Glenmavis, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Common questions in Glenmavis
Can you help a landlord with a rental near Coatdyke station?
Yes, landlords and agents are among the people we work for. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear price.
Is Glenmavis within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Can new sealant go on top of the old bead?
No. Fresh silicone doesn’t stick to the old layer, so sealing over the top fails quickly. We cut the old bead out completely.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Is it normal for sealant to crack in a new home?
A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.
Can I send you my snagging list?
Yes. Send us the sealant items on the list, with photos if you can, and we’ll quote. We will flag anything that needs another trade.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
Can you do several jobs on one visit?
Yes. Just list everything you need and we’ll quote it together.
Leave it or put it right?
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time, and they’re avoidable with good preparation. In a place like Glenmavis, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We will send you a clear quote for the lot.
