Glazing Silicone in Dartmouth Park
Professional glazing silicone in and around Dartmouth Park, with old sealant always removed completely and a 12-month guarantee.
- Rooflight joints letting water in
- Split or lifting silicone on glass
- A quick top-up bead that didn’t last
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Keep scrapers and blades away from the silicone
- Act on drips or damp patches early
- Check the silicone on glass every year or so
- Stick to mild cleaners on glass
Use mild cleaners on and around the silicone. Strong solvents can soften or mark it.
Act on black or lifting silicone early. Peeling silicone lets water in behind and the problem grows.
Glazing silicone in Dartmouth Park, done properly
Many conservatory leaks come down to failed sealant at the glass-to-frame or frame-to-wall joints. We find the joint that is letting water in and renew it and tell you plainly if the cause is something else. We work on rooflights, glass-to-glass joints and shower screens, and common reasons people get in touch are leaks from the base of a shower screen and water getting into a conservatory at the joints.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out.
You get a one-year guarantee, the same in Dartmouth Park as everywhere else we work.

What else we do in Dartmouth Park
DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
How it works
There is not much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours for most jobs. In a London area like Dartmouth Park, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- 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.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- New glazing silicone goes in and is tooled to a neat finish.
- We look over every joint and, where we can, test it with water.
Getting ready for the visit
- Clear items away from the joints we are working on
- Keep pets and children clear of the area while we work
- Where the joints are inside, avoid wetting them before we arrive

Advice
Leave it or put it right?
Leaks get worse, not better. Left, water can mark floors, damage plaster and rot timber, so it pays to deal with it early. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler for homes in Dartmouth Park.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.

Common questions in Dartmouth Park
Is parking a problem for a job in Dartmouth Park?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Can you do glazing silicone in Dartmouth Park?
Yes, Dartmouth Park is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Can you replace a misted double-glazed unit?
No. We renew the sealant. Glass and sealed units need a glazier.
How long should I leave it?
It depends on the product. Before we leave, we’ll tell you the cure time.
Which silicone is used for glass joints?
A neutral-cure glazing silicone that suits the glass and frame. Shower screens get anti-fungal silicone.
What does glazing silicone cost?
It depends on the job, so we quote each one individually. For a quick quote, ring 0345 464 0079 or drop us an email and let us know what needs doing and where.
Will resealing stop my conservatory leaking?
That depends where the water is getting in. Sealant joints we can renew but roof and panel problems need another trade.
When to call us in Dartmouth Park
Shower screen silicone gets wet every day. Mould grows into the bead and the joint starts to lift.
Keep an eye out for any of the following:
- Stained, discoloured glazing silicone
- Silicone pulling away from the glass
- Rooflight joints letting water in
- Leaks from the base of a shower screen
For an older house near a landmark such as Church of St Mary Brookfield, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What your quote should include
- What happens if they find a problem under the old sealant
- What product goes in the joint
- Who turns up on the day
- Which colour the sealant will be
How we quote for glazing silicone
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether the work is at height
- The amount of work
- How many rooms, windows or areas are involved
- Any mould that needs treating
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Photos by email, if that’s easy
- How we’d reach the joints
- Whether it’s a home or a business
- Roughly how big the job is
Need a quote? Please call 0345 464 0079 or drop us an email and tell us about the job. You’ll know what we plan to do, and what it will cost, before any work begins.
For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
What glazing silicone looks like in Dartmouth Park
With historic houses such as Witanhurst (about 0.8 miles north-west) nearby, there’s older building stock in the area around Dartmouth Park 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. In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking.
Dartmouth Park is in London, so parking needs planning: let us know about parking bays, permits or a driveway. Letting a property close to Gospel Oak station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.
