Glazing silicone in Markyate, done properly
Many conservatory leaks come down to failed sealant, where glass meets frame or frame meets wall. We find the joint that’s letting water in and renew it, and if it’s something sealant can’t fix, we will tell you. Typical jobs include leaks from the base of a shower screen and new silicone smeared over old sealant, on glass-to-glass joints, shower screens and conservatory frames.
Many houses in smaller places like Markyate have conservatories, garden rooms or patio doors. Those joints need the same attention as the main windows.

How to look after the new joints
So the new joints stay in good condition:
- Check the silicone on glass every year or so
- Do not use a blade near the sealant
- Keep harsh solvents off the silicone
- Open vents or windows to let moisture out
On shower screens, wipe or squeegee after use and keep the room ventilated. That slows mould growth on the bead.
Cracked glazing silicone means the joint has failed. Renewing it early keeps it simple, compared with repairing damaged frames or plaster.
What glazing silicone looks like in Markyate
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Letting a property close to Luton Airport Parkway station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. In the older streets around Markyate Methodist Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For site and facilities teams at buildings such as Markyate Village School and Nursery, larger buildings have plenty of frames, and the mastic around each one ages.

Advice
Common questions in Markyate
Is Markyate within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you cover Markyate for glazing silicone?
Yes. Our work covers London and the South East, and Markyate is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear quote.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Is it possible to redo the silicone on a shower screen?
Yes. We remove the old silicone carefully, and the joints are cleaned and resealed.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few pictures.
How long does glazing silicone take?
A typical job takes anything from an hour or two to most of a day, depending on the size of the job. Your quote will say how long we expect yours to take.
Different surfaces, different methods
Conservatory frames
The joints where the conservatory meets the house take a lot of movement. We reseal them with a sealant suited to the frame.
Glass-to-glass joints
Glass-to-glass joints depend entirely on the sealant. The bead needs to be tidy and fully bonded.
Landlord and commercial work in Markyate
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will quote.
If you manage several properties in or around Markyate, jobs at different addresses can be quoted together. Send us the addresses and the work at each, and pictures by email help.
Leave it or put it right?
Replacing windows or a shower screen isn’t needed for a failed joint. If the glass and frame are sound, new silicone is often all it takes. In a smaller place like Markyate, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Doing several joints on one visit is normally more efficient than separate visits. We’ll give you a clear quote for the lot.

DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
