How we handle glazing silicone in Broxbourne
Our work covers conservatory joints, rooflights and glass panels plus shower screens and the bases of glass balustrades. Each joint is cut out, cleaned and resealed. We work on glass balustrade bases, conservatory frames and shower screens, and the jobs we see most are a quick top-up bead that didn’t last and rooflight joints letting water in.
Homes around Broxbourne range from older properties to newer houses, and their windows range just as widely. Each frame material needs the right sealant against the right wall.
All of our work is guaranteed for twelve months, in Broxbourne and everywhere else we cover.

Looking after it afterwards
After the cure time, these simple habits help:
- Squeegee the shower screen after each use
- Check the gutters above the glazing for debris
- Open vents or windows to let moisture out
- Use a gentle glass cleaner and a soft cloth
Keep conservatory gutters clear, so water drains away from the joints. Overflowing gutters can cause leaks of their own.
A small conservatory leak soon spreads. Water runs along frames and down walls, so get it looked at when you first see it.
How the visit works
All our tools and materials come with us in the van. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes anything from an hour or two to most of a day, depending on the size of the job. Parking around Broxbourne is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- 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.
- We clean the joint with a solvent that suits the glass and frame.
- New glazing silicone goes in and is tooled to a neat finish.
- We look over every joint and, where we can, test it with water.
How to prepare
- Mention any tricky access
- Keep pets and children clear of the area while we work
- Mention any sign-in or site rules at work premises

Advice
Windows and doors in Broxbourne

Managing a site like Sheredes Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. Homes close to Church of St Augustine include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What happens if it’s left?
A quick bead over the old sealant might stop a drip for a while, but silicone does not stick to silicone and water soon finds its way back. A proper reseal is the lasting answer. In an older home around Broxbourne, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.

How we quote for glazing silicone
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Working hours on commercial sites
- The size of the job
- The old material and how stubborn it is
- Whether the work is at height
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
What to tell us for a quote
To help us quote quickly, let us know:
- Roughly how big the job is
- If it’s domestic, commercial or a hotel
- Where the job is, and your postcode
- Access, such as stairs, a lift or height
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. Whenever you’re ready, call 0345 464 0079 or email us.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
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.
