Glazing silicone in Leatherhead
Glazing joints need a sealant made for glass. We use a neutral-cure glazing silicone, which suits glass and most frame materials, finished with a neat, even bead. We’re often asked to deal with new silicone smeared over old sealant and failed joints on frameless glass, across conservatory frames, glass balustrade bases and glass-to-glass joints.
Leatherhead mixes older streets, where windows have often been replaced, with newer estates fitted with uPVC. In every case, the joint between frame and wall is what keeps water out.
There’s a 12-month guarantee on every job.

Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Get a new leak looked at quickly
- Use a gentle glass cleaner and a soft cloth
- Squeegee the shower screen after each use
- Avoid strong solvents on or near the sealant
Keep the new joints dry for as long as we advise. After that, clean glass with a mild cleaner.
Damp patches, drips and condensation along a joint are worth checking. The cause may be sealant or another part, and we will tell you which.
DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
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.
What affects the cost of glazing silicone
The price is agreed before any work begins. It takes into account:
- How many areas need sealing
- When we can work, for business premises
- Which sealant suits the joint
- How easy the joints are to reach
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

What we do, step by step
There is not much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes anything from an hour or two to most of a day, depending on the size of the job, including the tidy-up. In Leatherhead, parking is rarely complicated, though it helps to know about driveways or restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- First we agree the joints to be done.
- Old sealant is removed from the glass and frame.
- We clean and prepare the joint.
- New glazing silicone goes in and is finished neatly.
- We inspect the work and test it where we can.
Getting ready for the visit
- Move anything stored near the joints
- Tell us about any water getting in

What glazing silicone looks like in Leatherhead
With historic houses such as Polesden Lacey (about 3.4 miles south-west) nearby, there’s older building stock in the area around Leatherhead as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Leatherhead Trinity School and Children's Centre, the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as Church of Our Lady and St Peter, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For landlords with property near Leatherhead station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Surface by surface

Where two panes meet, the silicone joint takes all the movement. The bead needs to be tidy and fully bonded.
Shower screens
Most shower screen leaks come from the wall or tray joint. Both are resealed with anti-fungal silicone.

What do you need from me for a quote?
The location, the problem and the rough size of the job. Photos by email help too.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint.
How do I get a quote for glazing silicone in Leatherhead?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before work begins.
Do you have insurance?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Can you just put new silicone over the old?
New silicone won’t bond to old silicone and water gets between the layers. The old bead always comes out first.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
