Glazing silicone in High Cross
Glass replacement is not something we do, and misting between panes means a failed sealed unit. Our work is the sealant joints and that is often where the water gets in. If you are dealing with water running down inside the glass and a quick top-up bead that didn’t last, we can help.
Somewhere as small as High Cross, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Every job comes with our one-year guarantee.

When it isn’t the sealant
We will always be straight with you, so here’s what sealant cannot fix:
- A roof that has moved or dropped
- Condensation trapped between two panes
- Water coming through the roof rather than a sealant joint
If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer.
Surfaces we seal
- Rooflights
- Shower screens
- Glass balustrade bases
- Conservatory frames
- Glass-to-frame joints
- Glass-to-glass joints
What happens if it’s left?
If the problem is a misted unit or a broken panel, sealant will not help. We will tell you that rather than seal it anyway, so you can call the right trade. Around High Cross, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
Why High Cross clients choose us
- Anti-fungal sanitary silicone in wet areas
- A sealant colour to suit the surroundings
- Old sealant always removed completely
- We leave the area clean and tidy
Different surfaces, different methods
Rooflights
A rooflight faces rain and sun from above. Its sealant ages faster than vertical joints.
Glass balustrade bases
Outdoor balustrade joints face the weather. A sound sealant joint keeps them tidy and dry.
Can I do it myself?
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, then guaranteed for a year.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

What else we do in High Cross
What we do, step by step
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours, depending on how many joints need doing, and the area is left clean. Somewhere as small as High Cross, 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.
- The old sealant is removed from the glass and frame without scratching them.
- The glass and frame are cleaned and degreased.
- We apply a neutral-cure glazing silicone and tool it smooth.
- We check the joints and, where safe, run water over them.
How to prepare
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints
- Move anything stored near the joints
Getting a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.

Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Run a squeegee over the glass when you are done
- Stick to mild cleaners on glass
- Use gentle products around the joints
- Do not leave a drip for the next storm
Use mild cleaners on and around the silicone. Strong solvents can soften or mark it.
Shower screen leaks can go unnoticed. Water can soak into the floor or reach the room below long before you see it.
High Cross: your questions answered
Do you cover smaller places like High Cross?
Yes. High Cross 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.
Can you help a landlord with a rental near Ware station?
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 will give you a clear quote.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Can you replace a misted double-glazed unit?
No. We renew the sealant. Glass and sealed units need a glazier.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.

Frames and glazing around High Cross
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 Much Hadham Palace (about 4.2 miles east) nearby, there’s older building stock in the area around High Cross as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you live in an older home near Church of St John the Evangelist, the joint between an old wall and a newer frame is usually the first place rain gets in. Letting a property close to Ware station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows. Managing a site like Thundridge Church of England Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.
