When it is not the sealant
Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- A roof that has moved or dropped
- Frames that have decayed or split
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.
Surfaces we seal

- Glass balustrade bases
Glazing silicone in Sandridge
Sealant on glazing does not last for ever. Sun, rain and movement wear it down, and once it cracks, water follows. Resealing puts that right. If you’re dealing with water escaping where a screen meets the wall and glass-to-glass joints that have split, we can put it right, on shower screens, conservatory frames and rooflights alike.
Somewhere as small as Sandridge, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Whatever the size of the job, it’s backed by our one-year guarantee.

DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Why it’s worth doing now in Sandridge
Resealing cannot fix a failed unit or a cracked panel. We will tell you that rather than seal it anyway, so you can call the right trade. In a small place like Sandridge, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

What affects the cost of glazing silicone
Your quote is based on your job. We take into account:

- How many areas need sealing
- Whether old sealant or filler has to be cut out
- Access and height
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. We give a clear quote before we start.

- Where the job is, and your postcode

Sandridge questions
Can you do glazing silicone in Sandridge?
Yes. We work across London and the South East, and Sandridge is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
Is Sandridge within the area you cover?
Yes, Sandridge is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Are you fully insured?
Yes, we are fully insured.
Is balustrade sealant something you do?
Yes. The sealant joint at the base can be renewed. Fitting glass is a separate trade.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Do you fit new glass or sealed units?
We don’t replace glass. We look after the sealant joints, and we’ll tell you if a unit looks like it has failed.
Can landlords and businesses book you?
Yes. As well as householders, we work for landlords, agents, businesses and hotels across Hertfordshire.
Looking after it afterwards
Looking after new joints is easy:
- Don’t leave a drip for the next storm
- Squeegee the shower screen after each use
- Keep air moving in the conservatory
- Keep harsh solvents off the silicone
Follow the cure time we give you before the joints get wet so the silicone can set properly. After that, clean glass with a mild cleaner.
A small conservatory leak soon spreads. Water travels along the frame and into the wall so it’s best dealt with right away.
Windows and doors in Sandridge
Historic houses like Childwickbury Manor (about 2 miles west) are a reminder that the area around Sandridge has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to St Leonard's Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Rented homes near St Albans station change hands often, and leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. Managing a site like Sandridge School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Rooflights
Rooflights get the full force of the weather. The sealant around the glass and frame wears faster than most.
Shower screens
Mouldy or lifting sealant on a screen leaks. Cutting it out and resealing fixes it.
