Glazing silicone for homes and businesses in Haslar
Cracked, stained or lifting silicone on glass spoils the look and lets water in. We remove it without scratching the glass or frame before the new bead goes in. Common call-outs are for split or lifting silicone on glass and shower screens leaking along the wall or tray, on shower screens, rooflights and conservatory frames.
Homes in small places like Haslar often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Use a gentle glass cleaner and a soft cloth
- Check the silicone on glass every year or so
- Do not leave a drip for the next storm
- Squeegee the shower screen after each use
Do not use blades or scrapers near the bead when you clean. A soft cloth or sponge is best.
Do not leave lifting or mouldy silicone on glazing. Peeling silicone lets water in behind and the leak gets worse.
Your questions about glazing silicone in Haslar
Do you work for landlords with property near Portsmouth Harbour station?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can go on one quote. Just call 0345 464 0079 or email us with the address and what needs doing, and we’ll send you a clear quote.
Does living near the coast affect glazing silicone in Haslar?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area.
What does glazing silicone cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before work begins.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or email us.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Frames and glazing around Haslar
Haslar is close to 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. 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.
Homes close to St Francis include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. Letting a property close to Portsmouth Harbour station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
What we can’t put right
We will not take on work that won’t last, so here’s what sealant cannot put right:
- Glass that needs replacing
- Leaks from the roof covering or flashing (a roofer’s job)
- A sagging or failing conservatory roof
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think before booking.

How the visit works
There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes anything from an hour or two to most of a day, depending on the size of the job, including the tidy-up. Somewhere as small as Haslar, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at the glazing and agree which joints need resealing.
- We cut away the failed silicone.
- 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.
Preparing for the visit
- Tell us about any water getting in
- Try not to wet indoor joints just before the visit
- Plan for the work area to be out of bounds to pets and children

Related advice
What happens if it’s left?
Topping up old silicone can look like a fix, but new silicone won’t bond to old, and the leak generally returns. A proper reseal is the lasting answer. In a small place like Haslar, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, call 0345 464 0079 or send us an email for an honest opinion and a quote.

When to call us in Haslar
On shower screens, constant water and cleaning products wear silicone. Mould grows into the bead and the edges begin to peel.
Common reasons people contact us include:
- Leaking glazing joints on a rooflight
- Water running down inside the glass
- Shower screens leaking along the wall or tray
- Silicone pulling away from the glass
For site and facilities teams at buildings such as Haselworth Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
