- Water escaping where a screen meets the wall
- Drips on the inside of a conservatory window
- A quick top-up bead that didn’t last
How to look after the new joints
To keep the joints looking good and working properly:
- Don’t use a blade near the sealant
- Keep air moving in the conservatory
- Run a squeegee over the glass when you are done
- Keep harsh solvents off the silicone
Do not use blades or scrapers near the bead when you clean. Stick to a soft cloth.
A small conservatory leak soon spreads. Water travels along the frame and into the wall, so get it looked at when you first see it.
Glazing silicone in Mark Hall North
Sealant on glazing does not last for ever. Sun, rain and movement wear it down, and once it cracks, water follows. Renewing it keeps glazing joints doing their job. Common call-outs are for water running down inside the glass and failed joints on frameless glass, on conservatory frames, glass balustrade bases and glass-to-glass joints.
Many houses in smaller places like Mark Hall North have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.

For landlords and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
What happens if it’s left?
Topping up old silicone can look like a fix, but silicone does not stick to silicone, and the leak generally returns. Cutting out and resealing properly lasts. In an older home around Mark Hall North, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
Why us?

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. 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.

Mark Hall North: your questions answered
Do you cover smaller places like Mark Hall North?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
I let a flat near Harlow Town station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
Can you just put new silicone over the old?
Silicone does not stick to silicone and water gets between the layers. The old bead always comes out first.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Do you guarantee glazing sealant work?
There’s a 12-month guarantee on every job, glazing sealant included.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do you have insurance?
Yes. We are fully insured.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will explain our choice.
Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- A sealed unit that has misted inside
- A frame that needs repairing or replacing
- A sagging or failing conservatory roof
If in doubt, call 0345 464 0079 or email us and we’ll say what we think before you book.

Signs you need glazing silicone in Mark Hall North
Sealant laid over old sealant does not last. Many failed joints we see have been topped up rather than cut out, and water gets between the layers.
If you can see any of these, it’s time to have the joints looked at:
- Leaks from the base of a shower screen
- Glass-to-glass joints that have split
- Leaks where conservatory glass meets the frame
- Water running down inside the glass
Homes close to St Andrew's Methodist Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Advice
Frames and glazing around Mark Hall North
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Mark Hall North is part of Harlow, one of the post-war new towns. Many homes date from the post-war decades, and many will have had their original windows replaced. That mastic ages as well, and sills and frame heads are where leaks start.
For site and facilities teams at buildings such as Tany's Dell Primary School and Nursery, the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Harlow Town station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.
