Glazing silicone in Northney, done properly
Frameless shower screens rely on sealant to keep water in. Leaks normally come from the wall joint or the tray joint and both get fresh anti-fungal silicone. We work on conservatory frames, rooflights and glass balustrade bases, and common reasons people get in touch are new silicone smeared over old sealant and silicone pulling away from the glass.
Outdoor sealant needs dry, clean surfaces, so work on frames around Northney is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.

Landlord and commercial work in Northney
We work for landlords and letting agents as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together.
DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Northney homes and the weather
Northney 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. With historic houses such as Warblington Castle (about 1.1 miles north) nearby, there’s older building stock in the area around Northney as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you live in an older home near Church of St Peter, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For site and facilities teams at buildings such as Warblington School, the mastic around its windows and doors needs looking after like any other building’s.

What affects the cost of glazing silicone
The quote reflects the job in front of us. We take into account:
- The amount of work
- The type of sealant required
- Whether the work is at height
- Any mould that needs treating
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will explain what it covers.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- Any access issues, like height or stairs
- Whether it has been sealed before
- What the problem is, such as mould, gaps, leaks or cracking
- Where the property is
Getting a quote is simple: let us know what needs doing and where and its rough size. Photos by email help us understand the job, and we’ll come back to you with a quote.

When something else is needed
New sealant can’t fix everything, and we’d rather say so up front. It will not solve:
- Leaks from the roof covering or flashing (a roofer’s job)
- Cracked or broken glass
- Condensation trapped between two panes
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before you book.
Joints and surfaces we work on
- Rooflights
- Glass-to-frame joints
- Conservatory frames
- Glass balustrade bases
- Shower screens
- Glass-to-glass joints
When to call us in Northney
Not every leak is a sealant problem: failed roof panels, slipped glazing bars and blocked gutters cause them too. That is why we trace the leak first.
These are the problems we are asked about most:
- Sealant that was laid over old silicone and failed
- Leaks from the base of a shower screen
- Stained, discoloured glazing silicone
- Silicone pulling away from the glass
Rented homes near Warblington station change hands often, and glazing joints are worth checking at the end of a tenancy, before a small leak grows.
What to look for in a quote
- What happens if they find a problem under the old sealant
- Who does the work, and how experienced they are
- Which colour the sealant will be
- Is the old sealant removed completely?
Keeping the joints in good condition
After the cure time, these simple habits help:
- Do not use a blade near the sealant
- Keep conservatory gutters clear of leaves
- Check the silicone on glass every year or so
- Stick to mild cleaners on glass
Keep the new joints dry for as long as we advise. From then on, a mild glass cleaner is all it needs.
Conservatory leaks rarely stay small. Water travels along the frame and into the wall so it’s best dealt with straight away.
Northney: your questions answered
Does the coastal weather in Northney affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Will you come out to Northney?
Yes. Northney is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can I choose the sealant colour?
We help you choose a colour that suits. The product needed can limit the range.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
When is the sealant fully cured?
It depends on the product. Before we leave, we will tell you the cure time.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
How long will you be here?
That depends on the amount of work, but as a guide it takes a few hours, depending on how many joints need doing. We will tell you when we quote.
How it works
All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for most jobs. Somewhere like Northney needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We trace the leak and confirm it’s a sealant joint.
- We remove the old sealant carefully.
- We clean the glass and frame so the new silicone bonds.

- We check the finished joints and test with water where it’s safe.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can

- For business premises, tell us about site rules or sign-in
