Glazing silicone in Rosewell
Frameless shower screens rely on sealant to keep water in. The joint down the wall and the one along the tray are common leak points and both get fresh anti-fungal silicone. We work on rooflights, glass balustrade bases and shower screens, and people most often call us about leaks from the base of a shower screen and split or lifting silicone on glass.
Mastic can only go onto a dry joint, so outside work in Rosewell depends on the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
Big or small, it’s backed by our 12-month guarantee.

How the job changes by surface
Glass-to-frame joints
Old sealant is removed carefully from the glass and reseal with glazing silicone.
Glass-to-glass joints
Frameless glass corners and panels are joined with silicone. We renew it with a clear or matching glazing silicone.
DIY sealant or a professional job?
If you are set on DIY, put the effort into 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.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
How we quote for glazing silicone
Call for a quick quote. What matters most is:
- Working hours on commercial sites
- The number of rooms or windows
- Whether the work is at height
- The old material and how stubborn it is
Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear quote for the lot.
What we need to know
Before you ask for a quote, have a think about:
- What’s wrong with the joints now
- If someone has resealed it before
- The address or postcode of the job
- How we’d reach the joints
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
How it works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take a few hours for most jobs. For a place like Rosewell, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We start by finding the leak and making sure sealant is the cause.
- The old sealant is removed from the glass and frame without scratching them.
- The glass and frame are cleaned and degreased.
- Glazing silicone suited to the joint is applied and tooled.
- We look over every joint and, where we can, test it with water.
How to prepare
- Mention any sign-in or site rules at work premises
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we’re working on
Getting a quote
Getting a quote is simple: let us know the job and the location. A few pictures by email make the job easier to understand.

What glazing silicone looks like in Rosewell
Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Historic houses like Melville Castle (about 3 miles north-east) are a reminder that the area around Rosewell has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
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. For landlords with property near Newtongrange station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. Homes close to Rosewell Parish Church include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.
Rosewell is about 2 miles south-west of Bonnyrigg, in Midlothian. Rosewell gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a 12-month guarantee. 33 places in Midlothian are on our list, large and small.

Why act early in Rosewell
Replacing windows or a shower screen is not needed for a failed joint. If the glass and frame are sound, new silicone is often all it takes, and we will tell you if that is not the case. 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.

Aftercare tips
After the cure time, these simple habits help:
- Get a new leak looked at quickly
- Use a gentle glass cleaner and a soft cloth
- Avoid strong solvents on or near the sealant
- Keep conservatory gutters clear of leaves
Squeegee a shower screen after each shower and keep the room ventilated. It helps stop mould getting into the silicone.
Act on black or lifting silicone early. Peeling silicone lets water in behind and the leak gets worse.
Your questions about glazing silicone in Rosewell
Do you cover smaller places like Rosewell?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Can you do glazing silicone in Rosewell?
Yes. We work across all of Scotland, and Rosewell is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing, and we’ll give you a clear price.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Is a special sealant needed for glass?
We use a neutral-cure glazing silicone that suits the glass and frame. Shower screens get anti-fungal silicone.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
