How the visit works
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours, depending on how many joints need doing. Parking around Southminster is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We start by finding the leak and making sure sealant is the cause.
- The old sealant is removed from the glass and frame without scratching them.
- 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.
- The finished joints are checked and, where it’s safe, tested with water.
How to prepare
- Clear items away from the joints we are working on
- Let us know about stairs, lifts or work at height
- Let us know about parking restrictions

How we handle glazing silicone in Southminster
Glass, frames and walls all move at different rates, so the sealant between them does a lot of work. Once it splits or comes away, water finds a way through. We cut it out and reseal with a glazing silicone suited to the joint. We work on shower screens, glass-to-frame joints and conservatory frames, and people most often call us about mouldy sealant around glass panels and glazing silicone that has cracked or come away.
Homes around Southminster range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.
Every job comes with a 12-month guarantee.

Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

Frames and glazing around Southminster
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Southminster station, glazing joints are worth checking at the end of a tenancy, before a small leak grows. For an older house near a landmark such as Church of St Leonard, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

When to call us in Southminster
The wrong sealant is a common cause. Not every silicone sticks properly to glass and vinegar-smelling acetoxy silicone can attack some metals.
Keep an eye out for these signs:
- Water escaping where a screen meets the wall
- Mouldy sealant around glass panels
- Rooflight joints letting water in
- New silicone smeared over old sealant
Schools such as Southminster Church of England Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
Before you book anyone
- Is VAT in the price?
- How long the guarantee is
- How much experience the applicator has
- Whether they’re fully insured
What happens if it’s left?
Fixing a leaking screen early protects what’s underneath. Water from a failed joint can soak into the floor before it shows. In a smaller place like Southminster, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.

Aftercare tips
So the new joints stay in good condition:
- Ventilate the conservatory to cut condensation
- Keep harsh solvents off the silicone
- Do not leave a drip for the next storm
- Avoid scraping close to the bead
Look over the glazing joints every year or so. Catching a split early keeps the repair small, before water gets in.
Do not leave lifting or mouldy silicone on glazing. Once it starts to peel, water gets behind it and the leak gets worse.
