Surface by surface
Rooflights
Rooflight leaks can come from the sealant or the roof. We find the cause first.
Shower screens
Frameless screens rely on silicone at the base and wall. We reseal without scratching the glass.
How we handle glazing silicone in Dora's Green
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. We work on glass-to-glass joints, rooflights and shower screens, and common reasons people get in touch are black or yellowed silicone on glass joints and failed sealant around rooflight glass.
Homes in small places like Dora's Green often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
There’s a 12-month guarantee on every job, large or small.

How we quote for glazing silicone
Jobs vary more than people expect. The main factors:
- How many areas need sealing
- Working hours on commercial sites
- How easy the joints are to reach
- How much old sealant there is and how hard it is to remove
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Pictures of the joints, sent by email
- Roughly how big the job is

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What glazing silicone looks like in Dora's Green
Historic houses like Farnham Castle (about 1.7 miles south-east) are a reminder that the area around Dora's Green has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as Crondall Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. In the older streets around St Mary's Church, the joint between an old wall and a newer frame is usually the first place rain gets in.
Dora's Green is about 2 miles north-west of Farnham, in Surrey.

Leave it or put it right?
Glazing joints need a sealant made for the job. General-purpose sealant from a DIY shop may not suit glass or the frame, so we use neutral-cure glazing silicone. Where a wall is exposed, as many are in small places like Dora's Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

When to call us in Dora's Green
Some conservatory leaks are not sealant at all: failed roof panels, slipped glazing bars and blocked gutters cause them too. That’s why we trace the leak first.
Look out for these signs:
- Conservatory leaks at frame and glazing joints
- Shower screens leaking along the wall or tray
- Failed sealant around rooflight glass
- Mouldy sealant around glass panels
If you let a flat or house near Farnham station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
