Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.

Advice
About our glazing silicone in Isle of Dogs
Many conservatory leaks come down to failed sealant at the glass-to-frame or frame-to-wall joints. We find the joint that’s letting water in and renew it and tell you plainly if the cause is something else. We are often asked to deal with silicone pulling away from the glass and new silicone smeared over old sealant, on glass-to-frame joints, glass balustrade bases and glass-to-glass joints.
London has a lot of flats and conversions, where windows are often on upper floors. Who looks after the outside of the frames can depend on the lease, so check that first.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

Landlords, agents and businesses in Isle of Dogs
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.

Isle of Dogs questions
Is parking a problem for a job in Isle of Dogs?
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.
Do you work for landlords with property near Greenwich station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
Is there any odour?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint before we leave.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before resealing.
Can you just put new silicone over the old?
Topping up is a common cause of leaks. A proper job means cutting out, cleaning and resealing.
Why it’s worth doing now in Isle of Dogs
Replacing a conservatory roof is major work. Where the water is getting in through sealant renewing the joint is the simpler fix. If the roof is the problem, we’ll say so. In a flat in Isle of Dogs, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Get a new leak looked at quickly
- Keep scrapers and blades away from the silicone
- Use a gentle glass cleaner and a soft cloth
- Keep harsh solvents off the silicone
Look over the glazing joints every year or so. Catching a split early keeps the repair small, before water gets in.
Do not leave lifting or mouldy silicone on glazing. Peeling silicone lets water in behind and the leak gets worse.
What the job involves on each surface
Glass balustrade bases
Balustrade bases are exposed outdoors. A sound sealant joint keeps them tidy and dry.
Conservatory frames
Frame joints face sun and rain all year. Renewed sealant keeps water out.
When it is not the sealant
We’d rather tell you now than do work that won’t last, so these are the limits:
- A sealed unit that has misted inside
- Glass that needs replacing
- A sagging or failing conservatory roof
If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer before booking.
Surfaces we seal
- Glass balustrade bases
- Rooflights
- Glass-to-glass joints
- Glass-to-frame joints
- Conservatory frames
- Shower screens
Do you need glazing silicone in Isle of Dogs?
Using a sealant not made for glass causes many failures. Not every silicone sticks properly to glass and vinegar-smelling acetoxy silicone can attack some metals.
Keep an eye out for these signs:
- Black or yellowed silicone on glass joints
- Rooflight joints letting water in
- Shower screens leaking along the wall or tray
- Split or lifting silicone on glass
If you let a flat or house near Greenwich station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

Glazing silicone in Isle of Dogs: local notes
With historic houses such as Queen's House (about 0.8 miles south-east) nearby, there’s older building stock in the area around Isle of Dogs 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. In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking.
As a London address, Isle of Dogs can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. For site and facilities teams at buildings such as Harbinger Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
