Kelvinhaugh: your questions answered
How is work on the outside of a tenement in Kelvinhaugh generally arranged?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds do not.
Can you help a landlord with a rental near Exhibition Centre station?
Yes. We work for letting agents and landlords as well as homeowners. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint.
How long does the job take?
As a guide, most jobs take a few hours per window, depending on the condition of the joints. Bigger jobs take longer.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll explain our choice.
Where is Mr Mastic based?
We work from Crawley. We cover Kelvinhaugh and the rest of Glasgow.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Can you seal over the old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Sand mastic in Kelvinhaugh, done properly
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditional guidance is not to paint over it and we’ll advise if you are redecorating. We work on sash and case windows, tenement windows and stone surrounds, and common reasons people get in touch are gaps where the frame meets the masonry and draughty sash windows at the surround.
Kelvinhaugh is in one of Scotland’s four big cities, where many older buildings are sandstone or granite. Natural stone around older windows needs a sealant that won’t mark or attack it, so acetoxy silicones, which can attack some stone, are best avoided.
Big or small, you get the same one-year guarantee in Kelvinhaugh and across Glasgow.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Clear gutters so water does not pour onto the windows
- Get any rot dealt with first
- Look over the window mastic once a year
- Renew mastic before redecorating the windows
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
Signs you need sand mastic in Kelvinhaugh
Decorating can disturb tired mastic. Many people find it crumbling when they prepare the windows.
Common reasons people contact us are:
- Failed mastic on an exposed elevation
- Window mastic to renew ahead of painting
- Gaps round a timber door in stone or brick
- Mastic dropping out of the joint
For site and facilities teams at buildings such as Church Street Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Windows and doors in Kelvinhaugh
The west of Scotland is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Rented homes near Exhibition Centre station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. If you live in an older home near Sandyford Henderson Memorial Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How the visit works
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours for a single window, longer for several. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. For a job in Kelvinhaugh, tell us the floor, how the door entry system works and where we can park nearby.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Clear the area around the work
- Let us know about stairs, lifts or work at height
