Glazing silicone in North End
Cracked, stained or lifting silicone on glass looks poor and can leak. We remove it without scratching the glass or frame before the new bead goes in. If you’re dealing with rooflight joints letting water in and new silicone smeared over old sealant, we can help, on conservatory frames, shower screens and rooflights alike.
Homes around North End 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.
A 12-month guarantee comes as standard, so you’re covered after we have gone.

How it works
You do not need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for most jobs for a typical job. In a smaller place like North End, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- First we agree the joints to be done.
- Old sealant is removed from the glass and frame.
- The surfaces are cleaned with a suitable solvent.
- We apply and tool the new silicone.
- We inspect the work and test it where we can.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks

Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
If you’ve already had a go yourself, that is fine. We cut it out and start again.

Glazing silicone in North End: local notes
North End is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on glazing joints and frame seals, which can dry out and crack sooner where a building faces the weather. 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.
For an older house near a landmark such as St. Mark’s, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Rented homes near Hilsea station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
North End is about 1 mile north of Portsmouth, in Portsmouth. Jobs in North End get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. North End is one of 19 places in Portsmouth where we work.

How the job changes by surface
Conservatory frames
The joints where the conservatory meets the house take a lot of movement. We reseal them with a sealant suited to the frame.
Rooflights
Rooflights get the full force of the weather. The sealant around the glass and frame wears faster than most.
North End questions
Will you come out to North End?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Does living near the coast affect glazing silicone in North End?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
How much does glazing silicone cost in North End?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before we start.
Do you work for landlords and businesses?
Yes. We work for householders, landlords, letting agents, businesses and hotels across Portsmouth.
Do you seal glass balustrade bases?
Yes. The sealant joint at the base can be renewed. Fitting glass is a separate trade.
Where are you based?
We are based in Crawley, and we cover South East England, London and all of Scotland.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Can you fix a leaking conservatory?
In many cases, as long as sealant is the cause. We trace the leak first, so you know what you’re paying for.
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Clean glass with a mild cleaner and a soft cloth
- Keep scrapers and blades away from the silicone
- Keep air moving in the conservatory
- Keep harsh solvents off the silicone
Squeegee a shower screen after each shower and keep the room ventilated. It helps stop mould getting into the silicone.
A leaking shower screen may not show at first. It can damage the floor or the ceiling below before you spot it.
What sealant work can’t fix
Before you book, it’s worth knowing the limits too:
- Leaks from the roof covering or flashing (a roofer’s job)
- A roof that has moved or dropped
- Glass that needs replacing
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.

Do you need glazing silicone in North End?
Sunlight breaks sealant down and roof joints get the most sun. Old silicone hardens, cracks and loses its grip on the glass.
The problems people normally mention when they call are:
- Water getting into a conservatory at the joints
- Black or yellowed silicone on glass joints
- Water tracking down the inner face of the glass
- Silicone pulling away from the glass
For site and facilities teams at buildings such as Corpus Christi Catholic Primary School, the mastic around its windows and doors needs looking after like any other building’s.
