Glazing silicone in Throcking, done properly
A frameless shower screen depends on its silicone. The joint down the wall and the one along the tray are common leak points and both get fresh anti-fungal silicone. If you have split or lifting silicone on glass and leaks from the base of a shower screen, we can put it right.
Homes in small places like Throcking often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
Your job is guaranteed for a year, as with all our work.

Throcking homes and the weather
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like Freman College? Then its window and door frames need their mastic kept sound, just like a home’s.

The process
Most of a good job is in the preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for most jobs. For a village or hamlet like Throcking, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We find where water is getting in and check whether it’s a sealant joint.
- 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.
- New glazing silicone goes in and is tooled to a neat finish.
- We check the joints and, where safe, run water over them.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Let us know if you’ve seen damp or leaks
- Plan for the work area to be out of bounds to pets and children

Related advice
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Inspect the sealant on glazing annually
- Don’t leave a drip for the next storm
- Squeegee the shower screen after each use
- Keep harsh solvents off the silicone
Squeegee a shower screen after each shower and let the room air. It helps stop mould getting into the silicone.
Cracked glazing silicone means the joint has failed. Resealing now is a small job, compared with repairing damaged frames or plaster.
What affects the cost of glazing silicone
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How much old sealant there is and how hard it is to remove
- The number of rooms or windows
- The number and length of the joints
- When we can work, for business premises
Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
What to tell us for a quote
To help us quote quickly, let us know:
- Photos by email, if that is easy
- Where the job is, and your postcode
- Access, such as stairs, a lift or height
- How many joints, rooms or windows are involved
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that is easy.
When to call us in Throcking
Glass and frames expand and contract with the temperature, and they don’t move by the same amount. Over years, that movement tears the silicone.
The most common problems we see are:
- Leaks where conservatory glass meets the frame
- A quick top-up bead that didn’t last
- Drips on the inside of a conservatory window
- Glazing silicone that has cracked or come away
If you live in an older home near Holy Trinity Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What the job involves on each surface
Shower screens
Frameless screens rely on silicone at the base and wall. We reseal without scratching the glass.
Conservatory frames
Conservatory frame joints are a common source of leaks. We cut out the old sealant and reseal.
Landlord and commercial work in Throcking
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
