Why act early in Northmoor
Resealing cannot fix a failed unit or a cracked panel. We will tell you that rather than seal it anyway and point you to a glazier or roofer. Around Northmoor, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before we start.
Why us?
- Full insurance on every job
- 20+ years of sealant experience

About our glazing silicone in Northmoor
Glass, frames and walls all move at different rates, and the silicone between them takes the strain. When it cracks or lets go, water gets in. We cut it out and reseal with a glazing silicone suited to the joint. We’re often asked to deal with leaks where conservatory glass meets the frame and mouldy sealant around glass panels, on glass-to-glass joints, shower screens and glass balustrade bases.
Homes in small places like Northmoor often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
There’s a 12-month guarantee on every job, large or small.

DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Your questions about glazing silicone in Northmoor
Will you come out to Northmoor?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
What guarantee comes with glazing silicone in Northmoor?
All our work, in Northmoor and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
How long before the joint can be used?
That depends on the sealant used, so please follow the time we give you.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient.
Is it enough to run a bead over the old sealant?
Many leaks we see come from exactly that. A proper job means cutting out, cleaning and resealing.
Can you replace a misted double-glazed unit?
No. Misting between panes means the sealed unit has failed and needs replacing by a glazier.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all.
The process
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take anything from an hour or two to most of a day, depending on the size of the job. Somewhere like Northmoor needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We trace the leak and confirm it’s a sealant joint.
- 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.
Before we arrive
- On commercial sites, let us know about site rules
- Mention any parking rules near the property
- Move anything stored near the joints

Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Squeegee the shower screen after each use
- Don’t leave a drip for the next storm
- Open vents or windows to let moisture out
- Use a gentle glass cleaner and a soft cloth
Don’t use blades or scrapers near the bead when you clean. A soft cloth or sponge is best.
Shower screen leaks can go unnoticed. Water can soak into the floor or reach the room below before you spot it.
How the job changes by surface
Glass balustrade bases
Outdoor balustrade joints face the weather. A sound sealant joint keeps them tidy and dry.
Shower screens
A screen’s wall joint and tray joint are where leaks start. Both are resealed with anti-fungal silicone.
What we cannot put right
A few problems are outside what sealant work can do:
- A frame that needs repairing or replacing
- Condensation trapped between two panes
- A sagging or failing conservatory roof
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think.

How we quote for glazing silicone
Jobs vary more than people expect. The main factors:
- Whether there’s mould to deal with
- Any working-time requirements on site
- Whether old sealant or filler has to be cut out
- Which sealant suits the joint
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and agree the price before starting.
Asking for a quote
You do not need to know the technical terms. Just tell us:
- The problem you’ve noticed
- The address or postcode of the job
- Whether it has been sealed before
- Photos by email, if that is easy
We quote each job on its own. Simply ring 0345 464 0079 or send us an email and describe the job, and pictures are welcome.
What glazing silicone looks like in Northmoor
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Appleton Manor (about 1.7 miles south-east) are a reminder that the area around Northmoor has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Homes close to Church of St Denys include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. In and around Northmoor, as anywhere, good glazing silicone starts with a clean, dry, properly prepared joint.
