How we handle glazing silicone in Winchmore Hill
Cracked, stained or lifting silicone on glass looks poor and can leak. We remove it without scratching the glass or frame before the new bead goes in. If you are dealing with shower screens leaking along the wall or tray and leaking glazing joints on a rooflight, we can help, whatever the surface.
Homes in small places like Winchmore Hill 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.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

How to look after the new joints
So the new joints stay in good condition:
- Run a squeegee over the glass when you’re done
- Avoid strong solvents on or near the sealant
- Avoid scraping close to the bead
- Inspect the sealant on glazing annually
Don’t use blades or scrapers near the bead when you clean. A soft cloth or sponge is best.
Don’t leave lifting or mouldy silicone on glazing. Once it starts to peel, water gets behind it and the leak gets worse.
How it works
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and clear up. It usually takes a few hours for most jobs. Somewhere as small as Winchmore Hill, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- 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.
Before we arrive
- Tell us if parking is tricky
- Let us know about earlier repairs to the joints
- Move anything stored near the joints

How the job changes by surface
Shower screens
Most shower screen leaks come from the wall or tray joint. We reseal both with anti-fungal silicone.
Rooflights
Rooflight glazing joints are cut out and renewed. Leaks from the roof itself need a roofer.
What affects the quote in Winchmore Hill
We do not publish a price list, because no two jobs are the same. What we look at:
- When we can work, for business premises
- Mould in or behind the old joints
- Access and height
- How many areas need sealing
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
What to tell us for a quote
When you call or email, it’s useful to know:
- The rough size of the job
- The address or postcode of the job
- What’s wrong with the joints now
- If it’s domestic, commercial or a hotel
There’s no standard price list. Instead, we give you a clear price for your job. To arrange one, call 0345 464 0079 or email us.
What we can’t put right
We will always be straight with you, so here’s what new sealant won’t do:
- Glass that needs replacing
- Leaks from the roof covering or flashing (a roofer’s job)
- Frames that have decayed or split
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly before you book.
What we seal
- Glass balustrade bases
- Shower screens

Frames and glazing around Winchmore Hill
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. With historic houses such as Hughenden Manor (about 4.5 miles west) nearby, there’s older building stock in the area around Winchmore Hill 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.
Managing a site like Coleshill Church of England Infant School? Then larger buildings have plenty of frames, and the mastic around each one ages. Homes close to Church of All Saints include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Beaconsfield station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Can you reseal a frameless shower screen?
Yes. We cut out the old silicone and reseal the glass-to-wall and glass-to-tray joints.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used before we leave.
DIY sealant or a professional job?
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.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
