- Split or lifting silicone on glass
- Leaks where conservatory glass meets the frame
- Black or yellowed silicone on glass joints
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Keep harsh solvents off the silicone
- Check the silicone on glass every year or so
- Clear the conservatory gutters regularly
- Keep air moving in the conservatory
Keep the new joints dry for as long as we advise so the silicone can set properly. From then on, a mild glass cleaner is all it needs.
Damp patches, drips and condensation along a joint are worth checking. It may be sealant, or something else, and we’ll tell you which.
Glazing silicone for homes and businesses in Hilsea
We don’t replace glass, and misting between panes means a failed sealed unit. What we do is the silicone around the glass, which is where many leaks start. We work on shower screens, conservatory frames and glass-to-frame joints, and the jobs we see most are leaks where conservatory glass meets the frame and split or lifting silicone on glass.
Around Hilsea, conservatories, garden rooms and patio doors are often part of the house. Those joints need the same attention as the main windows.
There’s a 12-month guarantee on every job.

Hilsea homes and the weather
Hilsea is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on glazing joints and frame seals, which can dry out and crack sooner where a building faces 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.
Schools such as Gatcombe Park Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as St Francis' Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What happens on the day
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes anything from an hour or two to most of a day, depending on the size of the job. A visit to Hilsea is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- The joint is cleaned and degreased.
- We lay the new bead and tool it smooth.
- Each joint is checked and, where possible, water-tested.
Getting ready for the visit
- Let us know about parking restrictions
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any sign-in or site rules at work premises

Your questions about glazing silicone in Hilsea
Is glazing silicone in a coastal place like Hilsea any different?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are normally the first to need attention.
Do you cover smaller places like Hilsea?
Yes, Hilsea is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you offer different sealant colours?
Most of the time, yes. We will explain which colours are available.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Can you just put new silicone over the old?
A top-up rarely holds. Fresh silicone won’t bond to cured silicone, so we remove the old sealant and clean the joint.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
How long does glazing silicone take?
It depends on the size of the job, but most jobs take anything from an hour or two to most of a day, depending on the size of the job. We will tell you when we quote.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and you’ll get one quote.
Why it’s worth doing now in Hilsea
You don’t need new glazing because the sealant has gone. If the glass and frame are sound, new silicone is often all it takes. In a smaller place like Hilsea, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.

Do you need glazing silicone in Hilsea?
Silicone won’t bond to a dirty surface. Where the joint wasn’t cleaned and degreased the sealant may lift within a few years.
Common reasons people contact us are:
- Leaking glazing joints on a rooflight
- Silicone pulling away from the glass
- New silicone smeared over old sealant
- Water escaping where a screen meets the wall
Rented homes near Hilsea station change hands often, and leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.
What your quote should include
- How long to leave it before use
- Whether the sealant suits the joint
- Are they insured?
- Who does the work, and how experienced they are
Different surfaces, different methods
Shower screens
Most shower screen leaks come from the wall or tray joint. We reseal both with anti-fungal silicone.
Conservatory frames
Exposed frame joints wear with the weather. A fresh bead seals them again.
