What affects the quote in Oakley
There’s no set price list, because no two jobs are the same. What we look at:
- Whether the work is at height
- Whether old sealant or filler has to be cut out
- Any working-time requirements on site
- The size of the job
Doing several joints on one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- Any previous sealing or DIY work
- A few pictures by email, if you can
- If it’s domestic, commercial or a hotel
- What’s wrong with the joints now
Call for a quick quote, or email us if that is easier. Describe what needs sealing and we will talk you through the work before giving you a price.
Glazing silicone in Oakley, done properly
We don’t replace glass, and misting between panes means a failed sealed unit. What we do is the silicone around the glass and that is often where the water gets in. We work on shower screens, glass-to-frame joints and glass-to-glass joints, and the jobs we see most are leaking glazing joints on a rooflight and new silicone smeared over old sealant.
In smaller places like Oakley, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

What we cannot put right
In fairness, there are a few things sealant won’t fix:
- Rotten or badly damaged frames
- Condensation trapped between two panes
- Structural problems with a conservatory roof
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.
Where we work in Oakley
- Shower screens
- Glass-to-glass joints
- Conservatory frames
- Rooflights
- Glass-to-frame joints
- Glass balustrade bases
Leave it or put it right?
Glazing joints need a sealant made for the job. A general-purpose tube may not bond well or may react with the frame, so we use neutral-cure glazing silicone. In an older home around Oakley, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts.
Why book with us
- Experience in homes, commercial sites and hotels
- Tidy, careful work
- Any old sealant cut out fully, not covered over
- White, clear, grey or another colour, product permitting
Surface by surface
Glass-to-frame joints
Where glass sits in a frame, silicone keeps water out. When it splits, water can get into the frame.
Conservatory frames
Leaks often start where the frame meets the wall. We cut out the old sealant and reseal.
Glazing silicone in Oakley: local notes
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.
If you live in an older home near St John's, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you let a flat or house near Overton station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Your questions about glazing silicone in Oakley
Do you work for landlords with property near Overton station?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. You can call 0345 464 0079 or email us with the details for a clear quote.
Will you come out to Oakley?
Yes. Oakley is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
How long does the job take?
It depends on the size of the job, but as a guide it takes anything from an hour or two to most of a day, depending on the size of the job. We will tell you when we quote.
Can you replace a misted double-glazed unit?
No. A misted unit has failed inside, and a glazier needs to replace it.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Where is Mr Mastic based?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
Can you work on commercial sites?
Yes. We can plan bigger jobs in stages.

What happens on the day
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the job takes a few hours, depending on how many joints need doing in most cases. A visit to Oakley is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- 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.
- We check the finished joints and test with water where it’s safe.
Getting ready for the visit
- Clear items away from the joints we’re working on
- Try not to wet indoor joints just before the visit
- Mention if the joints have been sealed before

Advice
Do you need glazing silicone in Oakley?
UV light ages silicone and roof joints get the most sun. It goes brittle, cracks and stops sticking to the glass and frame.
People generally contact us after spotting one of these:
- Cracked silicone between glass panels
- Split or lifting silicone on glass
- Leaks where conservatory glass meets the frame
- Sealant that was laid over old silicone and failed
For site and facilities teams at buildings such as Oakley CE Junior School, larger buildings have plenty of frames, and the mastic around each one ages.
