Glazing & conservatory sealant in Colwood, West Sussex
Glazing silicone across Colwood and nearby, with old sealant always removed completely.

- Glazing silicone that has cracked or come away
- Leaks from the base of a shower screen
How we handle glazing silicone in Colwood
We don’t replace glass and a misted double-glazed unit needs a glazier. What we do is the silicone around the glass, which is where many leaks start. We work on rooflights, glass-to-glass joints and conservatory frames, and the jobs we see most are split or lifting silicone on glass and leaking glazing joints on a rooflight.
Homes in small places like Colwood 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.
The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or email us.

What affects the cost of glazing silicone
For a quick quote, just ask. The main things that affect it are:
- Which sealant suits the joint
- The number and length of the joints
- How many rooms, windows or areas are involved
- Any working-time requirements on site
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or drop us an email for an honest opinion and a quote.
What we need to know
To make quoting easier, let us know:
- Any access issues, like height or stairs
- A few pictures by email, if you can
- What the problem is, such as mould, gaps, leaks or cracking
- The type of property
There’s no standard price list, because every job is different. Instead, we give you a clear price for your job. To get started, call 0345 464 0079 or send us an email.
Common problems we fix in Colwood
The wrong sealant is a common cause. Some products don’t bond well to glass and vinegar-smelling acetoxy silicone can attack some metals.
Keep an eye out for any of the following:
- Rooflight joints letting water in
- Water getting into a conservatory at the joints
- Glass-to-glass joints that have split
- A quick top-up bead that didn’t last
Around Colwood, as everywhere, glazing silicone is only as good as the preparation behind it.

What glazing silicone looks like in Colwood
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Tyes Place (about 3.4 miles north-east) nearby, there’s older building stock in the area around Colwood 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.

- First, we trace the leak and check it’s coming through a sealant joint.
- The old sealant is removed from the glass and frame without scratching them.
- We clean the joint with a solvent that suits the glass and frame.
- Glazing silicone suited to the joint is applied and tooled.
- The finished joints are checked and, where it’s safe, tested with water.

Is glazing silicone in Colwood guaranteed?
All our work, in Colwood and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Will you come out to Colwood?
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.
Can you fix a leaking conservatory?
Yes, when the leak is a failed sealant joint. If it’s a broken panel, failed unit or roof problem, we’ll tell you.
Is it enough to run a bead over the old sealant?
Many leaks we see come from exactly that. We remove the old silicone, clean the joint and reseal.
Do the sealants smell?
Some sealants have a smell while they cure. Ventilation helps.
Do you work for hotels and businesses?
Yes, regularly. Larger jobs can be planned room by room or area by area.
What sealant do you use on glazing?
We pick a glazing silicone to suit the materials. Neutral-cure products suit most glass and frames.

Glass-to-frame joints
We cut the old silicone from the glass without scratching it and reseal with glazing silicone.
Glass balustrade bases
Balustrade bases are exposed outdoors. A sound sealant joint keeps them tidy and dry.
Can I do it myself?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Clean glass with a mild cleaner and a soft cloth
- Look over the glazing joints once a year
- Ventilate the conservatory to cut condensation
- Get a new leak looked at quickly
Clear the conservatory gutters regularly so water doesn’t back up against the seals. Overflowing gutters can cause leaks of their own.
A small conservatory leak soon spreads. Water travels along the frame and into the wall, so get it looked at when you first see it.
