Different surfaces, different methods

Glass-to-glass joints
Where two panes meet, the silicone joint takes all the movement. The bead needs to be tidy and fully bonded.
About our glazing silicone in Little Stanmore
Across Little Stanmore, we reseal glazing joints in homes, offices and hotels. From conservatories to shower screens, it’s the same careful method, with a sealant chosen for the joint. We work on conservatory frames, glass-to-frame joints and glass-to-glass joints, and people most often call us about sealant that was laid over old silicone and failed and rooflight joints letting water in.
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, and access in Little Stanmore is something to talk through when you book.
Each job carries a 12-month guarantee.

Little Stanmore questions
Can you help a landlord with a rental near Mill Hill Broadway station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
Can parking be tricky for a visit in Little Stanmore?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
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.
What sealant do you use on glazing?
A glazing silicone chosen for the joint. Neutral-cure silicone is the usual choice, as some acetoxy types can attack certain metals.
Can I choose the sealant colour?
In most cases you can choose. We will tell you which colours the right product comes in.
Can you reseal a frameless shower screen?
Yes. We remove the old sealant and reseal the wall and tray joints.
Can you reseal the base of a glass balustrade?
Yes, where the base is finished with sealant. Photos help us see what’s there.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer.

Advice
Leave it or put it right?
A leaking joint will not fix itself. Left, water can mark floors, damage plaster and rot timber, so it pays to deal with it early. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in Little Stanmore.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.

When to call us in Little Stanmore
Shower screen silicone gets wet every day. Mould grows into the bead and the joint starts to lift.
The most common problems we see are:
- Sealant that was laid over old silicone and failed
- Water running down inside the glass
- Mouldy sealant around glass panels
- Glazing silicone that has cracked or come away
Homes close to Church of St Lawrence include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Frames and glazing around Little Stanmore
In a converted house or block, who looks after the windows depends on the lease, so check that before you book. With historic houses such as Headstone Manor (about 3.1 miles west) nearby, there’s older building stock in the area around Little Stanmore as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Little Stanmore is in London, so parking needs planning: let us know about parking bays, permits or a driveway. Rented homes near Mill Hill Broadway station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
