Glazing silicone in Rayners Lane, done properly
Sealant on glazing doesn’t last for ever. Weather and movement take their toll, and once it cracks, water follows. Resealing puts that right. We work on shower screens, glass-to-glass joints and rooflights, and common reasons people get in touch are split or lifting silicone on glass and leaks from the base of a shower screen.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in, in Rayners Lane as anywhere.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or send us an email.

How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Keep conservatory gutters clear of leaves
- Act on drips or damp patches early
- Inspect the sealant on glazing annually
- Use a gentle glass cleaner and a soft cloth
Squeegee a shower screen after each shower and let the room air. That slows mould growth on the bead.
Conservatory leaks rarely stay small. Water runs along frames and down walls, so get it looked at when you first see it.

Rayners Lane: your questions answered
Can parking be tricky for a visit in Rayners Lane?
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.
Can you help a landlord with a rental near Northolt Park station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Do you seal glass balustrade bases?
We can. The old sealant is removed and the joint resealed using a sealant that suits the materials.
Where is Mr Mastic based?
We are based in Crawley, and we cover South East England, London and all of Scotland.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Is a special sealant needed for glass?
We pick a glazing silicone to suit the materials. Neutral-cure products suit most glass and frames, as some acetoxy types can attack certain metals.
What should I tell you?
A short description and the location. If we need more, we will ask.
How it works
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes a few hours for most jobs, depending on the amount of work. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Rayners Lane. A visitor permit or a nearby bay makes the visit run more smoothly.
- We trace the leak and confirm it’s a sealant joint.
- The failed silicone is cut out without marking the glass or frame.
- We clean the glass and frame so the new silicone bonds.
- We lay the new bead and tool it smooth.
- We check the finished joints and test with water where it’s safe.

Why it’s worth doing now in Rayners Lane
If the problem is a misted unit or a broken panel, sealant will not help. We’ll tell you that rather than seal it anyway and point you to a glazier or roofer. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before work begins.

Should I try it myself first?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Glazing silicone in Rayners Lane: local notes
In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking. With historic houses such as Headstone Manor (about 1.7 miles north-east) nearby, there’s older building stock in the area around Rayners Lane as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For landlords with property near Northolt Park station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. If you live in an older home near St. Andrew’s Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
