Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Across Lasswade, we reseal glazing joints in homes, offices and hotels. From conservatories to shower screens, it’s the same careful method.

Landlord and commercial work in Lasswade
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
When to call us in Lasswade
On shower screens, constant water and cleaning products wear silicone. Mould gets into it and the edges begin to peel.
Keep an eye out for these signs:
- Stained, discoloured glazing silicone
- A quick top-up bead that didn’t last
- Failed joints on frameless glass
- Leaking glazing joints on a rooflight
Melville Castle, about 0.7 miles north-east, is one of the historic houses in the wider area around Lasswade, and older homes nearby need a sealant that suits their walls.

What affects the cost of glazing silicone
Jobs vary more than people expect. The main factors:
- When we can work, for business premises
- The number and length of the joints
- Whether there’s mould to deal with
- How easy the joints are to reach
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What we need to know
You do not need to know the technical terms. Just tell us:
- How many joints, rooms or windows are involved
- If it’s domestic, commercial or a hotel
- If someone has resealed it before
- Any access issues, like height or stairs
If you are in Lasswade and need glazing silicone, drop us a line at info@mrmastic.co.uk. Tell us what the problem is and where, and you will get a clear quote before work begins.
Why deal with it now?
Leaks get worse, not better. Left, water can mark floors, damage plaster and rot timber so early action saves a bigger repair. In an older home around Lasswade, damp from a failed joint can get into timber and plaster.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.

Glazing silicone in Lasswade: local notes
Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Historic houses like Melville Castle (about 0.7 miles north-east) are a reminder that the area around Lasswade has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Letting a property close to Eskbank station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. For site and facilities teams at buildings such as Lasswade High School Centre, larger buildings have plenty of frames, and the mastic around each one ages.
