What we’re called out for in Wandsworth
Not every leak is a sealant problem: broken panels, roof problems and blocked gutters can all let water in. That is why we trace the leak first.
Keep an eye out for any of the following:
- Drips on the inside of a conservatory window
- Failed joints on frameless glass
- Leaks from the base of a shower screen
- Conservatory leaks at frame and glazing joints
As a London address, Wandsworth can be tricky for parking: let us know about parking bays, permits or a driveway.
Before you book anyone
- How the surfaces are prepared before sealing
- Whether the sealant suits the joint
- What happens if the job turns out different
- What insurance they hold
Glazing silicone in Wandsworth
Across Wandsworth, 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 glass balustrade bases, conservatory frames and rooflights, and common reasons people get in touch are leaking glazing joints on a rooflight and drips on the inside of a conservatory window.
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.
There’s a 12-month guarantee on every job, large or small.

What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- The type of property
- Where the job is, and your postcode
- Pictures of the joints, sent by email
- Access, such as stairs, a lift or height
For a quote, ring 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. We will send you a clear quote before any work starts.
Work for landlords, hotels and businesses

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
Why act early in Wandsworth
Fixing a leaking screen early protects what’s underneath. Water from a failed joint can soak into the floor before you notice. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Wandsworth, 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 phone 0345 464 0079 or drop us an email.

How the job changes by surface
Glass-to-frame joints
We cut the old silicone from the glass without scratching it and reseal with glazing silicone.
Rooflights
Rooflights get the full force of the weather. The sealant around the glass and frame wears faster than most.
Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
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.

Common questions in Wandsworth
Is parking a problem for a job in Wandsworth?
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.
Do you cover Wandsworth for glazing silicone?
Yes. Our work covers London and the South East, and Wandsworth is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear price.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can you replace a misted double-glazed unit?
No. Misting between panes means the sealed unit has failed, and a glazier needs to replace it.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages.
Is a special sealant needed for glass?
A glazing silicone chosen for the joint. Neutral-cure silicone is the usual choice, as some acetoxy types can attack certain metals.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient.
How it works
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours for most jobs. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Wandsworth. A visitor permit or a nearby bay makes the visit run more smoothly.
- First, we trace the leak and check it’s coming through a sealant joint.
- We cut out the failed silicone, taking care of the glass and frame.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- We apply a neutral-cure glazing silicone and tool it smooth.
- We look over every joint and, where we can, test it with water.
Preparing for the visit
- Mention any parking rules near the property
- Move anything stored near the joints
- Mention any leaks or damp you’ve noticed

Advice
Frames and glazing around Wandsworth
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking.
If you look after a building such as St Anne's CofE Primary School, the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Wandsworth Town station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows.
