Glazing silicone in Northdown
Glass replacement is not something we do, and misting between panes means a failed sealed unit. Our work is the sealant joints, which is where many leaks start. Typical jobs include new silicone smeared over old sealant and black or yellowed silicone on glass joints, across shower screens, rooflights and conservatory frames.
In smaller places like Northdown, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. Each frame material needs the right sealant against the right wall.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

How to look after the new joints
A little care helps the new joints last. Our advice:
- Run a squeegee over the glass when you’re done
- Do not use a blade near the sealant
- Check the gutters above the glazing for debris
- Use a gentle glass cleaner and a soft cloth
Use mild cleaners on and around the silicone. Harsh solvents may damage the bead.
Drips or damp near a glazing joint shouldn’t be ignored. The cause may be sealant or another part, and we’ll tell you which.

FAQs for Northdown
Will you come out to Northdown?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
I let a flat near Broadstairs station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.
Is balustrade sealant something you do?
Yes. The old sealant is removed and the joint resealed using a sealant that suits the materials.
What guarantee do I get?
Our one-year guarantee covers every job.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
When to call us in Northdown
On shower screens, constant water and cleaning products wear silicone. Mould gets into it and the joint starts to lift.
Signs it’s time to call us include:
- Leaks where conservatory glass meets the frame
- Cracked silicone between glass panels
- Leaking glazing joints on a rooflight
- Leaks from the base of a shower screen
If you look after a building such as Palm Bay Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
What your quote should include
- The length of the guarantee
- Whether they’re fully insured
- How the surfaces are prepared before sealing
- Who turns up on the day
Honest limits
To be straight with you, there are a few things sealant will not fix:
- A roof that has moved or dropped
- Glass that needs replacing
- Rotten or badly damaged frames
If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before you book.

What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from an hour or two to most of a day, depending on the size of the job, and the area is left clean. Parking around Northdown is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- 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.
- Glazing silicone suited to the joint is applied and tooled.
- We check the joints and, where safe, run water over them.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Move anything stored near the joints
- Mention if the joints have been sealed before

Why deal with it now?
Replacing windows or a shower screen is not needed for a failed joint. If the glass and frame are sound, new silicone is often all it takes, and we’ll tell you if that’s not the case. Around Northdown, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or drop us an email and we will talk you through it.

Northdown homes and the weather
Northdown 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. That is hard on glazing joints and frame seals, especially on the side facing the sea. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to St Philip include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in. Rented homes near Broadstairs station change hands often, and leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

Different surfaces, different methods

Shower screens
A screen’s wall joint and tray joint are where leaks start. Both are resealed with anti-fungal silicone.
