About our glazing silicone in Hawthorn Hill
Glazing silicone that has yellowed, blackened or come away looks poor and can leak. We remove it without scratching the glass or frame and reseal the joint. We work on conservatory frames, glass-to-glass joints and glass-to-frame joints, and people most often call us about failed sealant around rooflight glass and glazing silicone that has cracked or come away.
Around Hawthorn Hill, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

Why deal with it now?
You do not need new glazing because the sealant has gone. Sound glass and frames usually just need resealing. In a small place like Hawthorn Hill, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

What we are called out for in Hawthorn Hill
The wrong sealant is a common cause. Some products don’t bond well to glass and vinegar-smelling acetoxy silicone can attack some metals.
It’s worth asking for a quote if you see:
- Mouldy sealant around glass panels
- Water tracking down the inner face of the glass
- Silicone pulling away from the glass
- Glass-to-glass joints that have split
If you look after a building such as Holyport College, the mastic around its windows and doors needs looking after like any other building’s.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Different surfaces, different methods
Shower screens
Silicone holds the water in on frameless screens. We renew it without marking the glass.
Glass-to-frame joints
Old sealant is removed carefully from the glass and reseal with glazing silicone.
What we can’t put right
In fairness, there are a few things sealant will not fix:
- A sealed unit that has misted inside
- Glass that needs replacing
- Structural problems with a conservatory roof
If you are not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Look over the glazing joints once a year
- Check the gutters above the glazing for debris
- Use gentle products around the joints
- Avoid scraping close to the bead
Check the joints once a year. Catching a split early keeps the repair small.
Damp patches, drips and condensation along a joint are worth checking. It may be sealant, or something else and we’ll find out which.
How the visit works
There is not much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes anything from an hour or two to most of a day, depending on the size of the job from start to finish. Somewhere as small as Hawthorn Hill, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- We apply a neutral-cure glazing silicone and tool it smooth.
- We check the joints and, where safe, run water over them.
Before we arrive
- Mention any parking rules near the property
- Plan for the work area to be out of bounds to pets and children
- Tell us about any water getting in

Windows and doors in Hawthorn Hill
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. Historic houses like St Leonard's Hill (about 3.8 miles east) are a reminder that the area around Hawthorn Hill has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
In the older streets around Church of St Michael and All Angels, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For landlords with property near Bracknell station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.
