Glazing silicone for homes and businesses in Well End
Many conservatory leaks come down to failed sealant at the glass-to-frame or frame-to-wall joints. We find the joint that’s letting water in and renew it, and if it’s something sealant can’t fix, we will tell you. If you have leaks from the base of a shower screen and glass-to-glass joints that have split, we can put it right.
Outdoor sealant needs dry, clean surfaces, so work on frames around Well End is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What the job involves on each surface
Glass balustrade bases
Balustrade bases are exposed outdoors. A sound sealant joint keeps them tidy and dry.
Glass-to-frame joints
Silicone at the glass edge seals it into the frame. When it splits, water can get into the frame.

How it works
When we arrive, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before work begins. The work normally takes a few hours for most jobs. Somewhere as small as Well End, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We find where water is getting in and check whether it’s a sealant joint.
- 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.
- 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
- Tell us about any water getting in
- Try not to wet indoor joints just before the visit
- Move anything stored near the joints

Why it’s worth doing now in Well End
Leaks get worse, not better. Left, water can mark floors, damage plaster and rot timber so early action saves a bigger repair. In a small place like Well End, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We’ll give you a clear price for the lot.
Why us?
- A sealant colour to suit the surroundings
- Neat joints and a tidy finish
- Over 20 years’ experience
- We agree the colour with you first

Honest limits
New sealant can’t fix everything, and we will tell you before we start. Sealant will not put right:
- A broken pane or roof panel
- A sagging or failing conservatory roof
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
If you’re not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.
Surfaces we seal
- Glass balustrade bases
- Glass-to-glass joints
- Glass-to-frame joints

Frames and glazing around Well End
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Wyllyotts Manor (about 3.3 miles north-east) are a reminder that the area around Well End has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Rented homes near Elstree & Borehamwood station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. Homes close to St Michael and All Angels Church include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Sealing over old silicone is the commonest DIY error. 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.
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Keep conservatory gutters clear of leaves
- Use a gentle glass cleaner and a soft cloth
- Get a new leak looked at quickly
- Keep harsh solvents off the silicone
Check the joints once a year. Catching a split early keeps the repair small, before water gets in.
Don’t leave lifting or mouldy silicone on glazing. Peeling silicone lets water in behind and the leak gets worse.
Common problems we fix in Well End
The wrong sealant is a common cause. Some products don’t bond well to glass, and acetoxy types can attack some frame materials.
Any of these means the joints need attention:
- Water escaping where a screen meets the wall
- Stained, discoloured glazing silicone
- Leaking glazing joints on a rooflight
- Failed joints on frameless glass
Schools such as Hertswood Academy are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
