Your questions about glazing silicone in Bloomsbury
Is parking a problem for a job in Bloomsbury?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Do you cover Bloomsbury for glazing silicone?
Yes, Bloomsbury is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and let us know what needs doing.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
When is the sealant fully cured?
It depends on the product. Before we leave, we will tell you the cure time.
Is a special sealant needed for glass?
A neutral-cure glazing silicone suited to glass and the frame. Shower screens get anti-fungal silicone.
Is balustrade sealant something you do?
Yes. We cut out the failed sealant and reseal the base joint using a sealant that suits the materials.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
About our glazing silicone in Bloomsbury
Across Bloomsbury, 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. Typical jobs include mouldy sealant around glass panels and water running down inside the glass, across glass-to-glass joints, conservatory frames and glass-to-frame joints.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. Over the years, the sealant around them shrinks, cracks and pulls away, which is when draughts and damp patches appear in homes in Bloomsbury.
You get a one-year guarantee, the same in Bloomsbury as everywhere else we work.

Glazing silicone in Bloomsbury: local notes
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. 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, Bloomsbury 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 UCL School of Slavonic and East European Studies, the mastic around its windows and doors needs looking after like any other building’s.
Bloomsbury is about 1 mile north-east of City of Westminster, in Greater London. Anywhere in NW1W, we can carry out glazing silicone at your property. Bloomsbury is one of 764 places in Greater London where we work.
We work across NW1W, W1T and NW1 for glazing silicone and the streets around it. We cover properties on Drury Lane, Euston Road and Duke's Road and the roads around them. Being close to the A401 and A501, Bloomsbury is simple for us to get to. If you’re just outside Bloomsbury, we cover St Pancras (1 mile north-east), Euston (1 mile north-west), Kings Cross (1 mile north), Holborn (1 mile east) and Fitzrovia (1 mile west). Larger places within reach include Kensington (4 miles south-west), Walthamstow (6 miles north-east), Hampstead (3 miles north-west), Ruislip (13 miles west), Brompton (3 miles south-west) and Stockwell (4 miles south).
Around Bloomsbury
We work in homes and buildings around Lincoln's Inn Fields, Pilsudski Institute of London and St George the Martyr Church of England Primary School. Other local landmarks include Queens Larder Public House (under half a mile south-east) and Maria Fidelis Catholic School FCJ (0.6 miles north-west). Bloomsbury’s nearest station is London Euston station, about 0.6 miles north-west of the centre. Other landmarks nearby include Montfichet's Tower (1.2 miles south-east) and National Hospital for Neurology and Neurosurgery (less than half a mile south-east). Green spaces nearby include Barnsbury Wood and Ludgate Hill.

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
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. Putting it right early is much less trouble.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

When to call us in Bloomsbury
New silicone over old silicone won’t bond. Many failed joints we see have been topped up rather than cut out, and water gets between the layers.
Look out for these signs:
- Rooflight joints letting water in
- Glass-to-glass joints that have split
- Water getting into a conservatory at the joints
- New silicone smeared over old sealant
Homes close to St George the Martyr Holborn include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Landlord and commercial work in Bloomsbury
Housing providers, facilities teams and property managers book us too in Bloomsbury and across Greater London. We can quote a run of properties together, and we’re fully insured for the work.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
How the visit works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a few hours for most jobs, depending on the amount of work. In Bloomsbury, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- 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.
- Each joint is checked and, where possible, water-tested.
Getting ready for the visit
- Clear items away from the joints we are working on
- Try not to wet indoor joints just before the visit
- Tell us about access, such as stairs, a lift or high-level joints
Ask for a quote
Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we’ll take it from there.
Advice
Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Clean glass with a mild cleaner and a soft cloth
- Keep harsh solvents off the silicone
- Keep scrapers and blades away from the silicone
- Clear the conservatory gutters regularly
Do not use blades or scrapers near the bead when cleaning the glass. Stick to a soft cloth.
Cracked glazing silicone means the joint has failed. Renewing it early keeps it simple compared with fixing water damage later.
How the job changes by surface
Glass-to-glass joints
You see these joints clearly, so we take care to leave a neat bead.
Glass balustrade bases
Balustrade bases are exposed outdoors. A sound sealant joint keeps them tidy and dry.
