Glazing silicone for homes and businesses in Dunn Street
Cracked, stained or lifting silicone on glass spoils the look and lets water in. It comes off cleanly, without marking the glass and reseal the joint. We work on rooflights, glass-to-glass joints and conservatory frames, and the jobs we see most are split or lifting silicone on glass and mouldy sealant around glass panels.
Somewhere as small as Dunn Street, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Whatever the size of the job, it’s backed by our one-year guarantee in Dunn Street and across Medway.

Dunn Street homes and the weather
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near Church of St Peter, the joint between an old wall and a newer frame is generally the first place rain gets in. If you look after a building such as Swingate Primary School, the mastic around its windows and doors needs looking after like any other building’s.

What’s near Dunn Street
Locally, jobs take us to homes and businesses close to South Wood and The Harrow pub, among other places. The closest station to Dunn Street is Rainham (Kent) station, roughly 3.3 miles north-east. Nearby you’ll also find KIMS hospital (2.8 miles south) and Allington Castle (3.4 miles south-west). For a walk, there’s Boxley Hills and Burham Down.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
What we can’t put right
To be straight with you, there are a few things sealant will not fix:
- Cracked or broken glass
- Failed flashing around a conservatory
- A sealed unit that has misted inside
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly before booking.

Why deal with it now?
Leaks get worse, not better. Water can damage frames, walls, flooring and furniture so early action saves a bigger repair. Older cottages and farmhouses around Dunn Street can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Inspect the sealant on glazing annually
- Open vents or windows to let moisture out
- Check the gutters above the glazing for debris
- Avoid scraping close to the bead
On shower screens, wipe or squeegee after use and let the room air. It helps stop mould getting into the silicone.
A leaking shower screen may not show at first. Water can soak into the floor or reach the room below long before you see it.
What happens on the day
We keep the work tidy and contained to the joints we’re treating, so you can get on with your day. The job normally takes anything from an hour or two to most of a day, depending on the size of the job, and we explain the cure time before we leave. Somewhere as small as Dunn Street, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

What we are called out for in Dunn Street
UV light ages silicone, especially on conservatory roofs. It goes brittle, cracks and stops sticking on the glass.
Keep an eye out for any of the following:
- Water running down inside the glass
- Glass-to-glass joints that have split
- Rooflight joints letting water in
- New silicone smeared over old sealant
Letting a property close to Rainham (Kent) station? Then a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
