Three Mills questions
Do you work for landlords with property near West Ham station?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Is parking a problem for a job in Three Mills?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Are you fully insured?
Yes. We’re fully insured.
How do I get a quote for glazing silicone in Three Mills?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Can you replace a misted double-glazed unit?
No. We renew the sealant. Glass and sealed units need a glazier.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Can I choose the sealant colour?
Generally, yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before any work starts.
Glazing silicone for homes and businesses in Three Mills
We work across Three Mills on glazing joints for homes and businesses. Conservatories, rooflights, glass panels and shower screens are all part of the job. If you have leaking glazing joints on a rooflight and conservatory leaks at frame and glazing joints, we can help.
Many London homes are flats, with windows high above the street. Who looks after the outside of the frames can depend on the lease, so check that first, and access in Three Mills is something to talk through when you book.
The work is covered for a year after we finish. If anything is not right with it, call 0345 464 0079 or email us.

Looking after it afterwards
Aftercare is simple:
- Keep harsh solvents off the silicone
- Clear the conservatory gutters regularly
- Get a new leak looked at quickly
- Open vents or windows to let moisture out
Clear the conservatory gutters regularly so water doesn’t back up against the seals. Blocked gutters can push water where it shouldn’t go.
Drips or damp near a glazing joint shouldn’t be ignored. It may be sealant, or something else and we’ll find out which.
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Windows and doors in Three Mills
In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you let a flat or house near West Ham station, glazing joints are worth checking at the end of a tenancy, before a small leak grows. As a London address, Three Mills can be tricky for parking: let us know about parking bays, permits or a driveway.

How it works
We keep the work tidy and contained to the area we are working on. Expect the work to take a few hours, depending on how many joints need doing, and we tell you how long to leave it before we go. In a London area like Three Mills, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- We clean the glass and frame so the new silicone bonds.
- A neutral-cure glazing silicone is applied and tooled.
- We check the finished joints and test with water where it’s safe.
Getting ready for the visit
- Mention any parking rules near the property
- Move anything stored near the joints
- Try not to wet indoor joints just before the visit

What else we do in Three Mills
What happens if it’s left?
Topping up old silicone can look like a fix, but new silicone won’t bond to old and water soon finds its way back. Cutting out and resealing properly lasts. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Three Mills, the repair is bigger than the sealant job would have been.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or email us and we will talk you through it.

What we are called out for in Three Mills
Sealant laid over old sealant does not last. Plenty of leaks come from a quick top-up over the old bead leaving a path for water.
It’s worth asking for a quote if you see:
- Shower screens leaking along the wall or tray
- Failed sealant around rooflight glass
- Conservatory leaks at frame and glazing joints
- Water running down inside the glass
In the older streets around St Mary's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What your quote should include
- Whether you can choose the colour
- Whether all the old sealant comes out first
- What the quote includes, VAT included or not
- Whether the sealant suits the joint
Surface by surface
Rooflights
We reseal the glazing joints on rooflights. Leaks from the roof itself need a roofer.
Glass-to-frame joints
Where glass sits in a frame, silicone keeps water out. A failed bead lets water in.
