Glazing silicone in Sunnymead
We don’t replace glass and a misted double-glazed unit needs a glazier. What we do is the silicone around the glass and that is often where the water gets in. We work on glass-to-glass joints, shower screens and glass-to-frame joints, and the jobs we see most are cracked silicone between glass panels and shower screens leaking along the wall or tray.
Around Sunnymead, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.
All of our work is guaranteed for twelve months.

How we quote for glazing silicone
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The product the joint needs
- How much old sealant there is and how hard it is to remove
- How many rooms, windows or areas are involved
- When we can work, for business premises
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.
Asking for a quote
To help us quote quickly, please include:
- What’s wrong with the joints now
- Where the property is
- A few photos by email, if you can
- If someone has resealed it before
Need a quote? Please call 0345 464 0079 or send us an email with a few details. You will know what we plan to do, and what it will cost, before any work begins.
Why deal with it now?
Replacing windows or a shower screen is not needed for a failed joint. Sound glass and frames generally just need resealing. In an older home around Sunnymead, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Why choose Mr Mastic in Sunnymead

Sunnymead: your questions answered
Can you help a landlord with a rental near Oxford Parkway station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear price.
Can you do glazing silicone in Sunnymead?
Yes, Sunnymead is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear quote.
Should I try DIY first?
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.
Can you reseal a frameless shower screen?
Yes, it’s a common job. The screen is resealed with anti-fungal silicone made for wet areas.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Is there any odour?
Some sealants have a smell while they cure. Ventilation helps.
How much does glazing silicone cost in Sunnymead?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Are you insured?
Yes, we’re fully insured for domestic and commercial work.
What sealant work can’t fix
We’ll always be straight with you, so here’s what new sealant won’t do:
- Leaks from the roof covering or flashing (a roofer’s job)
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- Frames that have decayed or split
If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before you book.
What we seal
- Conservatory frames
- Rooflights
- Glass balustrade bases
- Shower screens
- Glass-to-glass joints
- Glass-to-frame joints
Do you need glazing silicone in Sunnymead?
Glass and frames expand and contract with the temperature at different rates. Over years, that movement tears the silicone.
Signs it’s time to call us include:
- Water escaping where a screen meets the wall
- Water tracking down the inner face of the glass
- Mouldy sealant around glass panels
- Cracked silicone between glass panels
If you look after a building such as Cutteslowe Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Frames and glazing around Sunnymead
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Holywell Manor (about 2.1 miles south) are a reminder that the area around Sunnymead 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 is traditional sand mastic.
Letting a property close to Oxford Parkway station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows. For an older house near a landmark such as Roman Catholic Church of St Gregory and St Augustine, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Can I do it myself?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

The process
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from an hour or two to most of a day, depending on the size of the job. Parking around Sunnymead is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We trace the leak and confirm it’s a sealant joint.
- We remove the old sealant carefully.
- We clean the glass and frame so the new silicone bonds.
- We lay the new bead and tool it smooth.
- We check the finished joints and test with water where it’s safe.
Getting ready for the visit
- Let us know about parking restrictions
- Keep children and pets away from the work area
- For indoor joints, keep the area dry beforehand if you can

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Get a new leak looked at quickly
- Clear the conservatory gutters regularly
- Run a squeegee over the glass when you are done
- Use a gentle glass cleaner and a soft cloth
Check the joints once a year. Catching a split early keeps the repair small, before water gets in.
Conservatory leaks rarely stay small. Water travels along the frame and into the wall, so get it looked at when you first see it.
