About our glazing silicone in Bisham
Glazing silicone that has yellowed, blackened or come away looks poor and can leak. It comes off cleanly, without marking the glass and reseal the joint. We work on glass-to-frame joints, glass-to-glass joints and shower screens, and people most often call us about silicone pulling away from the glass and leaks from the base of a shower screen.
Mastic can only go onto a dry, clean joint, so window work in Bisham is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
There’s a 12-month guarantee on every job, whatever its size.

Can you quote for more than one area?

Different products cure at different speeds, so please follow the time we give you.

How the job changes by surface
Glass-to-glass joints
These joints are on show, so a straight, even finish matters.
Glass balustrade bases
Balustrade bases are exposed outdoors. Renewing the sealant keeps water out of the channel.
Landlord and commercial work in Bisham
If you manage several properties in or around Bisham, several properties can go on one quote. Just tell us the addresses and what each one needs, and photos by email help.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Leave it or put it right?
A new conservatory roof is a big job. Where the water is getting in through sealant renewing the joint is the simpler fix. If the roof is the problem, we will say so. Where a wall is exposed, as many are in small places like Bisham, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Leaving a failed joint usually makes the job bigger, not smaller. If you are unsure, phone 0345 464 0079 or email us and we will give you an honest view and a quote.

Do you need glazing silicone in Bisham?
Shower screen silicone gets wet every day. Mould gets into it and the joint starts to lift.
Any of these means the joints need attention:
- Water tracking down the inner face of the glass
- Sealant that was laid over old silicone and failed
- Mouldy sealant around glass panels
- Shower screens leaking along the wall or tray
If you look after a building such as Bisham Church of England Academy, its window and door frames need their mastic kept sound, just like a home’s.

The process
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours, depending on how many joints need doing. In a small place like Bisham, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we check where the water gets in.
- 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
- Tell us about any water getting in
- Clear the area around the work
- Mention any tricky access

Advice
Can I do it myself?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Windows and doors in Bisham
With historic houses such as Harleyford Manor (about 1.5 miles west) nearby, there’s older building stock in the area around Bisham as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Compared with the north and west, the South East gets less rain, 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 All Saints, 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 Marlow station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.
