DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
About our glazing silicone in Mark Hall South
Sealant on glazing doesn’t last for ever. Weather and movement take their toll, and once it cracks, water follows. Resealing puts that right. We work on glass-to-glass joints, conservatory frames and glass-to-frame joints, and people most often call us about a quick top-up bead that didn’t last and water escaping where a screen meets the wall.
In smaller places like Mark Hall South, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. Each frame material needs the right sealant against the right wall.
We stand behind the work with a 12-month guarantee, so you are covered after we’ve gone.

Glass-to-glass joints
Glass-to-glass joints depend entirely on the sealant. The bead needs to be tidy and fully bonded.
Shower screens
Silicone holds the water in on frameless screens. We reseal without scratching the glass.
How we quote for glazing silicone
You’ll get a clear quote before work begins. It’s based on:
- The number of rooms or windows

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
What to tell us for a quote
You don’t need to know the technical terms. Just tell us:

- Roughly how big the job is
- What the problem is, such as mould, gaps, leaks or cracking

Landlords, agents and businesses in Mark Hall South
We work for letting agents and landlords as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Check the gutters above the glazing for debris
- Avoid scraping close to the bead
- Wipe the screen down after showering
- Act on drips or damp patches early
Clear the conservatory gutters regularly, so water drains away from the joints. Overflowing gutters can cause leaks of their own.
Don’t leave lifting or mouldy silicone on glazing. Peeling silicone lets water in behind and the problem grows.
Mark Hall South: your questions answered
Should the sealant in an older Mark Hall South home be renewed?
Often, yes: cracked, shrunken or mouldy sealant has done its job. The key is cutting all the old sealant out, as new sealant will not bond to it.
I let a flat near Harlow Town station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear price.
How much does glazing silicone cost in Mark Hall South?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Why not top up the existing silicone?
A top-up rarely holds. The new bead cannot grip the old one so we take it all out and start clean.
Is the work guaranteed?
Our one-year guarantee covers every job, glazing sealant included.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we are using.
Do you reseal glass shower screens?
Yes. We remove the old sealant and reseal the wall and tray joints.
Why deal with it now?
Topping up old silicone can look like a fix, but new silicone won’t bond to old, and the leak normally returns. Cutting out and resealing properly lasts. Homes in smaller places like Mark Hall South can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.

Advice
What glazing silicone looks like in Mark Hall South
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Mark Hall South is part of Harlow, one of the post-war new towns. With many homes from the post-war decades, replacement windows and doors are common. The mastic around replacement frames ages too, and gaps at sills and frame heads are where water gets in.
For landlords with property near Harlow Town station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. For site and facilities teams at buildings such as Cooks Spinney Primary Academy and Nursery, the mastic around its windows and doors needs looking after like any other building’s. If you live in an older home near St Andrew's Methodist Church, the joint between an old wall and a newer frame is generally the first place rain gets in.
