Glazing silicone in Brentham Garden Suburb
Our work covers conservatory joints, rooflights and glass panels plus shower screens and the bases of glass balustrades. Each joint is cut out, cleaned and resealed. We’re often asked to deal with sealant that was laid over old silicone and failed and cracked silicone between glass panels, on glass-to-glass joints, glass-to-frame joints and rooflights.
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 Brentham Garden Suburb as anywhere.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

When to call us in Brentham Garden Suburb
Dirt and grease stop silicone sticking. Where the joint wasn’t cleaned and degreased the sealant may lift within a few years.
Signs it’s time to call us include:
- A quick top-up bead that didn’t last
- Cracked silicone between glass panels
- Water running down inside the glass
- Leaking glazing joints on a rooflight
Letting a property close to Ealing Broadway station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows.
What to look for in a quote
- Whether the sealant suits the joint
- Who does the work, and how experienced they are
- How long to leave it before use
- What happens if the job turns out different
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Keep air moving in the conservatory
- Use gentle products around the joints
- Keep conservatory gutters clear of leaves
- Do not leave a drip for the next storm
Use mild cleaners on and around the silicone. Harsh solvents may damage the bead.
Damp patches, drips and condensation along a joint are worth checking. The cause may be sealant or another part, and we will tell you which.
How the visit works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours for most jobs. For a job in Brentham Garden Suburb, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- The joint is cleaned and degreased.
- We lay the new bead and tool it smooth.
- We check the finished joints and test with water where it’s safe.
Preparing for the visit
- Mention if the joints have been sealed before
- Tell us if parking is tricky
- Plan for the work area to be out of bounds to pets and children

Advice
What happens if it’s left?
Glazing joints need a sealant made for the job. A general-purpose tube may not bond well or may react with the frame, so we use neutral-cure glazing silicone. 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 Brentham Garden Suburb, the repair is bigger than the sealant job would have been.
Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.
What you get with us
- Any old sealant cut out fully, not covered over
- Quality sealants from Arbo and Everbuild

FAQs for Brentham Garden Suburb
Is parking a problem for a job in Brentham Garden Suburb?
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.

How long before the joint can be used?
Cure times vary by product and the conditions. Before we leave, we’ll tell you the cure time.
Is it possible to redo the silicone on a shower screen?
Yes, it’s a common job. We use anti-fungal silicone made for wet areas.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Which silicone is used for glass joints?
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.

Are you fully insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Brentham Garden Suburb homes and the weather
In a converted house or block, who looks after the windows depends on the lease, so check that before you book. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Brentham Garden Suburb is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. Managing a site like St Gregory's Catholic Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.
