What affects the cost of glazing silicone
We quote each job individually. These are the things that affect it:
- The number and length of the joints
- Which sealant suits the joint
- Whether the work is at height
- The number of rooms or windows
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What we need to know
You do not need to know the technical terms. It helps if you can tell us:
- A few photos by email, if you can
- Roughly how big the job is
- What’s wrong with the joints now
- How we’d reach the joints
For a quote, ring 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. You’ll have a clear quote before work begins.
Glazing silicone in Woodend, done properly
Glass and frames expand and contract differently, and the silicone between them takes the strain. Once it splits or comes away, water finds a way through. We replace it with a glazing silicone that suits the glass and frame. We work on rooflights, glass-to-frame joints and glass balustrade bases, and the jobs we see most are leaks where conservatory glass meets the frame and stained, discoloured glazing silicone.
Outdoor sealant needs dry, clean surfaces, so work on frames around Woodend is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
Each job carries a 12-month guarantee, large or small.

Woodend questions
Can you help a landlord with a rental near Botley station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just call 0345 464 0079 or email us with the address and what needs doing, and we’ll send you a clear quote.
Do you cover Woodend for glazing silicone?
Yes. We work across London and the South East, and Woodend is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job.
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.
How long should I leave it?
Cure times vary by product and the temperature. Before we leave, we will tell you the cure time.
Can you reseal a frameless shower screen?
Yes. We cut out the old silicone and reseal the glass-to-wall and glass-to-tray joints.
Can you replace a misted double-glazed unit?
No, our work is the silicone. A glazier replaces glass and units.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Woodend, along with the rest of our area.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
How it works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for most jobs and we leave things clean and tidy. Somewhere like Woodend needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- The joint is cleaned and degreased.
- We lay the new bead and tool it smooth.
- Each joint is checked and, where possible, water-tested.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Tell us about any water getting in
- Try not to wet indoor joints just before the visit

Different surfaces, different methods
Glass-to-glass joints
Glass-to-glass joints depend entirely on the sealant. It must be clean, neat and well bonded.
Glass balustrade bases
Outdoor balustrade joints face the weather. A sound sealant joint keeps them tidy and dry.
What we can’t put right
We will always be straight with you, so here’s what new sealant will not do:
- Glass that needs replacing
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- Water coming through the roof rather than a sealant joint
If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer.
Surfaces we seal
- Rooflights
- Conservatory frames
- Glass balustrade bases
- Glass-to-glass joints

Woodend homes and the weather
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near Church of the Holy Trinity, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For landlords with property near Botley station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

When to call us in Woodend
Using a sealant not made for glass causes many failures. Not every silicone sticks properly to glass, and acetoxy types can attack some frame materials.
People normally contact us when they notice one of these:
- Silicone pulling away from the glass
- Conservatory leaks at frame and glazing joints
- Leaks from the base of a shower screen
- Failed joints on frameless glass
Managing a site like Swanmore College of Technology? Then larger buildings have plenty of frames, and the mastic around each one ages.
What your quote should include
- Who turns up on the day
- Whether all the old sealant comes out first
- What the cure time is
- How the surfaces are prepared before sealing
Why act early in Woodend
A quick bead over the old sealant might stop a drip for a while, but silicone doesn’t stick to silicone, and the leak normally returns. A proper reseal is the lasting answer. In a small place like Woodend, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
