What we do, step by step
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours, depending on how many joints need doing. Parking around Hersham is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We start by finding the leak and making sure sealant is the cause.
- Old silicone is cut away from the glass and frame without scratching either.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- Glazing silicone suited to the joint is applied and tooled.
- We look over every joint and, where we can, test it with water.
Getting ready for the visit
- Clear items away from the joints we are working on
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work

Advice
Glazing silicone in Hersham
A frameless shower screen depends on its silicone. Leaks generally come from the wall joint or the tray joint, and we reseal both. We work on conservatory frames, glass-to-glass joints and glass-to-frame joints, and people most often call us about water running down inside the glass and split or lifting silicone on glass.
In a smaller place like Hersham, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
Your job is guaranteed for a year, as with all our work.

What glazing silicone looks like in Hersham
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as The Homewood (about 1.4 miles south-east) nearby, there’s older building stock in the area around Hersham as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you look after a building such as Bell Farm Primary School, larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Walton-On-Thames station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. Homes close to Church of St Peter include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Glass-to-glass joints
You see these joints clearly, so we take care to leave a neat bead.
Rooflights
We reseal the glazing joints on rooflights. Leaks from the roof itself need a roofer.
Common questions in Hersham
Do you cover smaller places like Hersham?
Yes. Hersham is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Walton-On-Thames station. Can you help?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
What guarantee do I get?

Can you do several jobs on one visit?
Yes, we can. More than one area can be quoted together.
Do you do commercial work?

Do you replace glass?
No. Misting between panes means the sealed unit has failed, and a glazier needs to replace it.
What sealant work cannot fix
Before you book, it’s worth knowing the limits too:
- A frame that needs repairing or replacing
- Structural problems with a conservatory roof
- Water coming through the roof rather than a sealant joint
If you’re not sure, just call 0345 464 0079 or email us and we will give you a straight answer.
Joints and surfaces we work on
- Shower screens
- Conservatory frames
- Rooflights
- Glass balustrade bases
- Glass-to-glass joints
- Glass-to-frame joints
How to look after the new joints
Looking after new joints is easy:
- Act on drips or damp patches early
- Avoid scraping close to the bead
- Check the silicone on glass every year or so
- Keep air moving in the conservatory
Clear the conservatory gutters regularly so water doesn’t back up against the seals. Blocked gutters can push water where it shouldn’t go.
Shower screen leaks can go unnoticed. It can damage the floor or the ceiling below before you spot it.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
For landlords and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
