Glazing silicone for homes and businesses in Otford
Glazing joints need a sealant made for glass. We use a neutral-cure glazing silicone, which suits glass and most frame materials, finished with a neat, even bead. Common call-outs are for glass-to-glass joints that have split and sealant that was laid over old silicone and failed, across glass balustrade bases, shower screens and conservatory frames.
In a smaller place like Otford, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
Our work is backed for twelve months, in Otford and everywhere else we cover.

Why deal with it now?
Leaks get worse, not better. Left, water can mark floors, damage plaster and rot timber so early action saves a bigger repair. In an older home around Otford, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Why book with us
- A sealant colour to suit the surroundings
- We agree the colour with you first
- White, clear, grey or coloured to suit, where the product allows
- Sanitary silicone with an anti-fungal additive in wet areas
The process
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for most jobs. Parking around Otford is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We find where water is getting in and check whether it’s a sealant joint.
- Old silicone is cut away from the glass and frame without scratching either.
- We clean the joint with a solvent that suits the glass and frame.
- Glazing silicone suited to the joint is applied and tooled.
- The finished joints are checked and, where it’s safe, tested with water.
Preparing for the visit
- Keep children and pets away from the work area
- Move anything stored near the joints
- Mention if the joints have been sealed before

Your questions about glazing silicone in Otford
Will you come out to Otford?
Yes, Otford is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Otford station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll send you a clear quote.
Do you replace glass?
That’s not something we do. Misting between panes means the sealed unit has failed, and a glazier needs to replace it.
How long before the joint can be used?
Different products cure at different speeds, so please follow the time we give you.
Do you do commercial work?
Yes. We can plan bigger jobs in stages to suit the site.
Can you fix a leaking conservatory?
It depends on the cause. Sealant joints we can renew but roof and panel problems need another trade.
Can you reseal the base of a glass balustrade?
Yes, we reseal the joint at the base channel. Fitting glass is a separate trade.
Will there be a smell?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
What affects the quote in Otford
The quote reflects the job in front of us. We take into account:
- When we can work, for business premises
- Mould in or behind the old joints
- Which sealant suits the joint
- Whether old sealant or filler has to be cut out
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Ask us for a quote and we will explain what it covers.
Helping us quote
What to tell us when you ask for a quote:
- Any access issues, like height or stairs
- How many joints, rooms or windows are involved
- Whether it has been sealed before
- What the problem is, such as mould, gaps, leaks or cracking
To get a quote, call 0345 464 0079 or email us with the location and a short description of the problem. You will have a clear quote before work begins.
How to look after the new joints
Looking after new joints is easy:
- Avoid strong solvents on or near the sealant
- Get a new leak looked at quickly
- Keep conservatory gutters clear of leaves
- Keep scrapers and blades away from the silicone
Use mild cleaners on and around the silicone. Harsh solvents may damage the bead.
Conservatory leaks rarely stay small. Water runs along frames and down walls, so get it looked at when you first see it.
Honest limits
Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:
- Leaks from the roof covering or flashing (a roofer’s job)
- Condensation trapped between two panes
- Rotten or badly damaged frames
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.
Joints and surfaces we work on

Glazing silicone in Otford: local notes
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Knole House (about 3.2 miles south) nearby, there’s older building stock in the area around Otford as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Schools such as Otford Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Church of St Bartholomew, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Rented homes near Otford station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

What else we do in Otford
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.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
