Glazing silicone in Longstone, done properly
Glass replacement isn’t something we do, and misting between panes means a failed sealed unit. What we do is the silicone around the glass, which is where many leaks start. If you are dealing with failed sealant around rooflight glass and silicone pulling away from the glass, we can put it right.
Longstone is in one of Scotland’s four big cities, where many older buildings are sandstone or granite. Stone needs a sealant that suits it, which generally means a neutral-cure product or a traditional sand mastic rather than an acetoxy silicone.
Every job comes with a one-year guarantee.

Why deal with it now?
Replacing a conservatory roof is major work. Where the water is getting in through sealant renewing the joint is the simpler fix. If it’s the roof itself, we’ll tell you. Wind-driven rain gets into any failed joint on the outside of a city building, and in a tall building in Longstone, damp can travel a long way before it shows.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we will go through it with you.

Common questions in Longstone
How do repairs to the shared parts of a tenement in Longstone get organised?
Shared parts of a tenement, such as the roof and outside walls, are usually repaired with the agreement of the owners, often through a property factor. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Windows often belong to the individual flat, but it’s worth checking your deeds.
Do you work for landlords with property near Kingsknowe station?
Yes. We work for landlords and agents as well as homeowners. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear quote.
How long does glazing silicone take?
That depends on the amount of work, but most jobs take anything from an hour or two to most of a day, depending on the size of the job. We will give you a better idea when we quote.
Where are you based?
We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Can you replace a misted double-glazed unit?
Glass replacement is not our trade. We look after the sealant joints and can tell you if a unit seems to have gone.
Different surfaces, different methods
Glass-to-frame joints
Where glass sits in a frame, silicone keeps water out. When it splits, water can get into the frame.
Rooflights
A rooflight faces rain and sun from above. The sealant around the glass and frame wears faster than most.
The process
You do not need to clear the whole room or building, only the area right around the joints. We protect the rest, and the job takes a few hours, depending on how many joints need doing in most cases. In a city area like Longstone, parking may be by permit or pay-and-display, so tell us what’s nearby. For flats, mention the door entry system and any shared-stair arrangements.
- First we agree the joints to be done.
- Old sealant is removed from the glass and frame.
- The surfaces are cleaned with a suitable solvent.
- We apply and tool the new silicone.
- The joints are checked before we leave.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Clear items away from the joints we’re working on
- For business premises, tell us about site rules or sign-in

Advice
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Clear the conservatory gutters regularly
- Keep air moving in the conservatory
- Squeegee the shower screen after each use
- Inspect the sealant on glazing annually
Keep conservatory gutters clear so water does not back up against the seals. Blocked gutters can push water where it shouldn’t go.
A small conservatory leak soon spreads. Water runs along frames and down walls so it’s best dealt with right away.
Frames and glazing around Longstone
Historic houses like Whitefoord House (about 3.8 miles north-east) are a reminder that the area around Longstone has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Under the Tenements (Scotland) Act 2004, shared parts of a tenement, such as the roof and outside walls, are looked after by the owners together, often through a property factor. Windows usually belong to the flat, but the title deeds have the final say.
Whitefoord House, about 3.8 miles north-east, is one of the historic houses in the wider area around Longstone. Letting a property close to Kingsknowe station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. Schools such as Merchiston Castle School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you do try it yourself, take your time over the 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.
