What we do, step by step
On the day, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. Most jobs take anything from an hour or two to most of a day, depending on the size of the job. In a smaller place like Blackbird Leys, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- 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.
- A neutral-cure glazing silicone is applied and tooled.
- Each joint is checked and, where possible, water-tested.
Before we arrive
- On commercial sites, let us know about site rules
- Try not to wet indoor joints just before the visit
- Let us know if you’ve seen damp or leaks

How we handle glazing silicone in Blackbird Leys
Many conservatory leaks come down to failed sealant, where glass meets frame or frame meets wall. We trace the leak to the joint and reseal it and tell you plainly if the cause is something else. If you have leaking glazing joints on a rooflight and water getting into a conservatory at the joints, we can help, whatever the surface.
In a smaller place like Blackbird Leys, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. That’s hard on the mastic around frames and sills.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

For landlords and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can be quoted together.
Honest limits
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- A broken pane or roof panel
- A sealed unit that has misted inside
- A frame that needs repairing or replacing
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.
Surfaces we seal
- Glass-to-frame joints
- Glass balustrade bases
- Glass-to-glass joints
- Rooflights
- Conservatory frames
- Shower screens
Blackbird Leys homes and the weather
Historic houses like Garsington Manor (about 2.3 miles east) are a reminder that the area around Blackbird Leys has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Schools such as St John Fisher Catholic Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. If you let a flat or house near Radley station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

What else we do in Blackbird Leys
Do you need glazing silicone in Blackbird Leys?
Sealant laid over old sealant doesn’t last. Many failed joints we see have been topped up rather than cut out, and water gets between the layers.
Most people get in touch after spotting one of these:
- Cracked silicone between glass panels
- Water running down inside the glass
- Leaks from the base of a shower screen
- Split or lifting silicone on glass
For an older house near a landmark such as Church of the Holy Family, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What affects the quote in Blackbird Leys
Every job gets its own quote. These are the things that affect it:

The cost depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before work begins, so you know where you stand.

Your questions about glazing silicone in Blackbird Leys
Is Blackbird Leys within the area you cover?
Yes, we do. 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 do glazing silicone in Blackbird Leys?
Yes, Blackbird Leys is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job.
Is it enough to run a bead over the old sealant?
A top-up rarely holds. The new bead can’t grip the old one so we take it all out and start clean.
What guarantee do I get?
Every job comes with our 12-month guarantee.
Do you reseal glass shower screens?
We can. We remove the old silicone carefully, and the joints are cleaned and resealed.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Is a special sealant needed for glass?
A glazing silicone chosen for the joint. Neutral-cure products suit most glass and frames.
What does glazing silicone cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before any work starts.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Clean glass with a mild cleaner and a soft cloth
- Keep harsh solvents off the silicone
- Clear the conservatory gutters regularly
- Don’t use a blade near the sealant
On shower screens, wipe or squeegee after use and let the room air. That slows mould growth on the bead.
Don’t leave lifting or mouldy silicone on glazing. Once it starts to peel, water gets behind it and the leak gets worse.
