Problem with your glazing joints in Granborough? We remove the old material, prepare the joints and seal them properly.

Glazing silicone for homes and businesses in Granborough
Our work covers conservatory joints, rooflights and glass panels, as well as frameless shower screens and glass balustrade bases. The old sealant comes out, the joint is cleaned and new silicone goes in. If you have rooflight joints letting water in and glass-to-glass joints that have split, we can put it right, whatever the surface.
Outdoor sealant needs dry, clean surfaces, so work on frames around Granborough is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
You get a one-year guarantee, the same in Granborough as everywhere else we work.

What the job involves on each surface
Glass-to-glass joints
These joints are on show, so a straight, even finish matters.
Glass balustrade bases
The base joint is cut out and resealed. We don’t install or replace glass.
Granborough: your questions answered
Is glazing silicone in Granborough guaranteed?
All our work, in Granborough and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Do you cover Granborough for glazing silicone?
Yes. Our work covers London and the South East, and Granborough is part of that. You can ring 0345 464 0079 or send us an email and let us know what needs doing.
Can you match the sealant colour?
In most cases you can choose. We will tell you which colours the right product comes in and agree one before work begins.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you replace glass?
No, our work is the silicone. Glass and sealed units need a glazier.
Do you work for letting agents?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels across Buckinghamshire.
Is a special sealant needed for glass?
Glass needs a sealant made for glazing. We use neutral-cure glazing silicone and anti-fungal silicone in wet areas.
What do you need from me for a quote?
Tell us what needs doing and where, plus photos if you have them. We’ll ask anything else we need to know.
When it isn’t the sealant
We will not take on work that will not last, so these are the limits:
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- Glass that needs replacing
- Frames that have decayed or split
If in doubt, ring 0345 464 0079 or email us and we will say what we think before booking.
What we seal
- Glass-to-glass joints
- Glass balustrade bases
- Glass-to-frame joints
- Rooflights
- Conservatory frames
- Shower screens
DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Leave it or put it right?
Dealing with a leaking shower screen early protects the floor and ceiling. A small leak can reach the floor below before you notice. Around Granborough, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Why book with us
- Old sealant always removed completely
- White, clear, grey or coloured to suit, where the product allows
- We’re fully insured
- We agree the colour with you first

What affects the quote in Granborough
We quote each job individually. This is what makes a difference:
- Working hours on commercial sites
- The old material and how stubborn it is
- How many areas need sealing
- The type of sealant required
What you pay reflects the work, not guesswork. That’s why we ask about the job first and agree the price before starting.
What we need to know
Before you ask for a quote, have a think about:
- The type of property
- What the problem is, such as mould, gaps, leaks or cracking
- Where the job is, and your postcode
- Whether it has been sealed before
We do not publish a price list, because every job is different. Instead, we send you a clear quote for your job. To get started, ring 0345 464 0079 or email us.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Act on drips or damp patches early
- Check the gutters above the glazing for debris
- Wipe the screen down after showering
- Use gentle products around the joints
Keep the new joints dry for as long as we advise so the silicone can set properly. From then on, a mild glass cleaner is all it needs.
If silicone on glass has cracked, water is already getting in. Renewing it early keeps it simple, compared with repairing damaged frames or plaster.
The process
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours for most jobs. In a small place like Granborough, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by finding the leak and making sure sealant is the cause.
- We cut out the failed silicone, taking care of the glass and frame.
- We clean the joint with a solvent that suits the glass and frame.
- Glazing silicone suited to the joint is applied and tooled.
- The finished joints are checked and, where it’s safe, tested with water.
Getting ready for the visit
- Mention if the joints have been sealed before
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any parking rules near the property

Advice
Frames and glazing around Granborough
With historic houses such as Claydon House (about 2.9 miles west) nearby, there’s older building stock in the area around Granborough as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around Church of St John the Baptist, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For site and facilities teams at buildings such as Sir Thomas Fremantle School, larger buildings have plenty of frames, and the mastic around each one ages.
