Windows and doors in Cranbourne
Historic houses like St Leonard's Hill (about 1.5 miles north-east) are a reminder that the area around Cranbourne has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around Church of St Peter, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Letting a property close to Ascot station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

How we handle glazing silicone in Cranbourne
Cracked, stained or lifting silicone on glass spoils the look and lets water in. It comes off cleanly, without marking the glass and reseal the joint. We work on shower screens, glass-to-glass joints and glass-to-frame joints, and the jobs we see most are mouldy sealant around glass panels and failed sealant around rooflight glass.
Around Cranbourne, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What affects the cost of glazing silicone
Every job gets its own quote. These are the things that affect it:
- Mould in or behind the old joints
- The old material and how stubborn it is
- The number of rooms or windows
- Which sealant suits the joint
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Call for a quick quote and we’ll explain what it covers.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- How we’d reach the joints
- Any previous sealing or DIY work
- The rough size of the job
- If it’s domestic, commercial or a hotel
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
What we cannot put right
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Failed flashing around a conservatory
- Structural problems with a conservatory roof
- Rotten or badly damaged frames
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before booking.
What we seal
- Glass balustrade bases
- Conservatory frames
- Shower screens

Cranbourne: your questions answered
Do you work for landlords with property near Ascot station?
Yes, we work for letting agents and landlords. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Do you cover Cranbourne for glazing silicone?
Yes, Cranbourne is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we will send you a clear quote.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do you have insurance?
Yes, we’re fully insured for every job we do.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Can you quote for more than one area?
Yes. Several rooms, windows or areas can go on one quote.
Why not top up the existing silicone?
Silicone doesn’t stick to silicone and water gets between the layers. We cut out the old sealant first.
Do you reseal glass shower screens?
Yes. We cut out the old silicone and reseal the glass-to-wall and glass-to-tray joints.
For landlords and businesses
If you manage several properties in or around Cranbourne, several properties can be quoted together. Send us the addresses and the work at each.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Signs you need glazing silicone in Cranbourne
UV light ages silicone and roof joints get the most sun. Old silicone hardens, cracks and loses its grip on the glass.
If you can see any of these, it’s time to have the joints looked at:
- New silicone smeared over old sealant
- Failed joints on frameless glass
- Glazing silicone that has cracked or come away
- Mouldy sealant around glass panels
Schools such as Cranbourne Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
What your quote should include
- How long to leave it before use
- How long the guarantee is
- Whether they’re fully insured
- Whether the sealant suits the joint

Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Do not leave a drip for the next storm
- Avoid scraping close to the bead
- Check the silicone on glass every year or so
- Wipe the screen down after showering
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.
A leaking shower screen may not show at first. It can damage the floor or the ceiling below long before you see it.
