Glazing silicone in Adelphi, done properly
A frameless shower screen depends on its silicone. Leaks generally come from the wall joint or the tray joint and both get fresh anti-fungal silicone. Typical jobs include water escaping where a screen meets the wall and black or yellowed silicone on glass joints, across conservatory frames, glass-to-frame joints and rooflights.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Adelphi: your questions answered
Is Adelphi in your area for glazing silicone?
Yes. We work across London and the South East, and Adelphi is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing.
I let a flat near London Charing Cross station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can go on one quote. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can you match the sealant colour?
Generally, yes. White, clear and grey are common, and other colours are available for many products, and we will agree it with you first.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we’re using.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Can you just put new silicone over the old?
Many leaks we see come from exactly that. A proper job means cutting out, cleaning and resealing.
Is the work guaranteed?
Our one-year guarantee covers every job, glazing sealant included.

Frames and glazing around Adelphi
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. In London conversions and blocks, the lease decides who is responsible for the frames, so check that before you book.
Adelphi is in London, so parking needs planning: let us know about parking bays, permits or a driveway. If you look after a building such as St Clement Danes CofE Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Common problems we fix in Adelphi
Some conservatory leaks are not sealant at all: broken panels, roof problems and blocked gutters can all let water in. That is why we trace the leak first.
Most people get in touch after spotting one of these:
- Water escaping where a screen meets the wall
- Black or yellowed silicone on glass joints
- Sealant that was laid over old silicone and failed
- Conservatory leaks at frame and glazing joints
Rented homes near London Charing Cross station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

Honest limits
Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- Condensation trapped between two panes
- Frames that have decayed or split
- Failed flashing around a conservatory

How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for most jobs, and the area is left clean. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- 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.
- A neutral-cure glazing silicone is applied and tooled.
- Each joint is checked and, where possible, water-tested.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Let us know about stairs, lifts or work at height
- Mention if the joints have been sealed before

Quotes for glazing silicone in Adelphi
Some jobs are bigger than they look, and some smaller. The main factors:
- The type of sealant required
- Any mould that needs treating
- When we can work, for business premises
- Whether old sealant or filler has to be cut out
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and give you a clear quote before we start.
Helping us quote
You don’t need to know the technical terms. It helps if you can tell us:
- The type of property
- If someone has resealed it before
- What’s wrong with the joints now
- How we’d reach the joints
If you’re in Adelphi and need glazing silicone, ring 0345 464 0079 or send us an email. Tell us what the problem is and where, and we’ll agree the price before any work begins.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Stick to mild cleaners on glass
- Don’t leave a drip for the next storm
- Avoid strong solvents on or near the sealant
- Open vents or windows to let moisture out
Keep conservatory gutters clear, so water drains away from the joints. Blocked gutters can push water where it shouldn’t go.
If silicone on glass has cracked, water is already getting in. Renewing it early keeps it simple, compared with repairing damaged frames or plaster.
DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
Work for landlords, hotels and businesses
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
