About our glazing silicone in Hanworth
Our work covers conservatory joints, rooflights and glass panels, as well as frameless shower screens and glass balustrade bases. The old sealant comes out, the joint is cleaned and new silicone goes in. We work on conservatory frames, glass balustrade bases and rooflights, and the jobs we see most are water getting into a conservatory at the joints and silicone pulling away from the glass.
London has a lot of flats and conversions, where windows are often on upper floors. In a converted house or block, the lease usually says who is responsible for the windows, so it’s worth checking before booking.
The work is covered for a year after we finish. If anything is not right with it, call 0345 464 0079 or drop us an email.

What affects the quote in Hanworth
There’s no set price list, because no two jobs are the same. What we look at:
- Any mould that needs treating
- Working hours on commercial sites
- How many areas need sealing
- Whether the work is at height
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and give you a clear quote before we start.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- If someone has resealed it before
- Photos by email, if that is easy
- Where the job is, and your postcode
- Access, such as stairs, a lift or height
Getting a quote is simple: tell us what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we’ll come back to you with a quote.

What else we do in Hanworth
Common problems we fix in Hanworth
Not every leak is a sealant problem: broken panels, roof problems and blocked gutters can all let water in. We find the cause before we seal anything.
Signs it’s time to call us include:
- Failed sealant around rooflight glass
- Leaks where conservatory glass meets the frame
- Mouldy sealant around glass panels
- Sealant that was laid over old silicone and failed
Letting a property close to Hampton station? Then a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
Before you book anyone
- How much experience the applicator has
- Whether they seal over old material or remove it
- How the surfaces are prepared before sealing
- What happens if the job turns out different
Can I do it myself?
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

What information do you need?
A short description and the location, plus photos if you have them. If we need more, we’ll ask.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
Can you replace a misted double-glazed unit?
We do not replace glass. We reseal the joints around it, and we’ll tell you if a unit looks like it has failed.
Are you insured?
Yes. We’re fully insured.
Do you do commercial work?
Yes. We can plan bigger jobs in stages.
What we can’t put right

- A frame that needs repairing or replacing
- Structural problems with a conservatory roof
- A sealed unit that has misted inside
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.

The process
On the day, we start by going over the job with you, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. The work generally takes anything from an hour or two to most of a day, depending on the size of the job. In Hanworth, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- We find where water is getting in and check whether it’s a sealant joint.
- Old silicone is cut away from the glass and frame without scratching either.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- New glazing silicone goes in and is tooled to a neat finish.
- We look over every joint and, where we can, test it with water.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Keep pets and children clear of the area while we work
- Clear the area around the work

Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Keep air moving in the conservatory
- Check the gutters above the glazing for debris
- Use a gentle glass cleaner and a soft cloth
- Avoid strong solvents on or near the sealant
Check the joints once a year. Catching a split early keeps the repair small.
Don’t leave lifting or mouldy silicone on glazing. Once it starts to peel, water gets behind it and the leak gets worse.
For landlords and businesses
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Windows and doors in Hanworth
Historic houses like Strawberry Hill House (about 2 miles east) are a reminder that the area around Hanworth has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
As a London address, Hanworth can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. Schools such as Buckingham Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
