Glazing silicone for homes and businesses in Hoddesdon
Conservatory leaks often start at a sealant joint at the glass-to-frame or frame-to-wall joints. We find the joint that is letting water in and renew it and tell you plainly if the cause is something else. We work on rooflights, glass balustrade bases and shower screens, and people most often call us about a quick top-up bead that didn’t last and stained, discoloured glazing silicone.
Walls in Hoddesdon that face the prevailing wind take the most weather, so the mastic there tends to fail first. It’s worth looking at every frame, not just the one that leaks.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

What glazing silicone looks like in Hoddesdon
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.
Homes close to Church of St Catherine & St Paul include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in. Schools such as Sheredes School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Why it’s worth doing now in Hoddesdon
If the problem is a misted unit or a broken panel, sealant won’t help. We will tell you that rather than seal it anyway, so you can call the right trade. In a family home in Hoddesdon, a failed seal around a bath or a frame lets water into places you can’t see, such as under the floor, behind a panel or into a wall. Whatever the joint, failed sealant only gets worse.
Doing several joints on one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

How long does the job take?

Can you work on commercial sites?

Will the old sealant be removed?

Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. It usually takes a few hours for most jobs. In Hoddesdon, parking is rarely complicated, though it helps to know about driveways or restrictions, and let us know if the work is upstairs, in a flat or up high outside.

Landlords, agents and businesses in Hoddesdon
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can be quoted together.
How to look after the new joints
After the cure time, these simple habits help:
- Clear the conservatory gutters regularly
- Avoid strong solvents on or near the sealant
- Run a squeegee over the glass when you are done
- Open vents or windows to let moisture out
Don’t use blades or scrapers near the bead when you clean. Stick to a soft cloth.
Damp patches, drips and condensation along a joint are worth checking. The cause may be sealant or another part and we will find out which.
How the job changes by surface
Glass-to-glass joints
Silicone joins glass panels in many frameless designs. We renew it with a clear or matching glazing silicone.
Rooflights
Rooflights get the full force of the weather. The sealant around the glass and frame wears faster than most.

When to call us in Hoddesdon
Sealant laid over old sealant doesn’t last. Many failed joints we see have been topped up rather than cut out, and water gets between the layers.
People usually contact us after spotting something like this:
- Mouldy sealant around glass panels
- New silicone smeared over old sealant
- Water tracking down the inner face of the glass
- Failed sealant around rooflight glass
For landlords with property near Broxbourne station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
