Lavendon Glazing Silicone
Glazing joints in Lavendon need attention? We remove the old material, prepare the joints and seal them properly, with a 12-month guarantee.
- Conservatory leaks at frame and glazing joints
- Rooflight joints letting water in
- Mouldy sealant around glass panels
DIY versus a professional finish
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 doesn’t work out, we can still put it right.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Glazing silicone for homes and businesses in Lavendon
We renew glazing silicone on conservatories, rooflights and glass panels, as well as frameless shower screens and glass balustrade bases. Each joint is cut out, cleaned and resealed. Typical jobs include glass-to-glass joints that have split and shower screens leaking along the wall or tray, on glass-to-glass joints, glass balustrade bases and glass-to-frame joints.
Mastic can only go onto a dry, clean joint, so window work in Lavendon is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Each job carries a 12-month guarantee, whatever its size.

Leave it or put it right?
Leaks get worse, not better. Left, water can mark floors, damage plaster and rot timber so early action saves a bigger repair. Where a wall is exposed, as many are in small places like Lavendon, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Lavendon homes and the weather
With historic houses such as Turvey Abbey (about 2 miles east) nearby, there’s older building stock in the area around Lavendon 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. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Managing a site like Lavendon School? Then its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as Church of St Michael, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Lavendon is about 7 miles north-east of Newport Pagnell, in Milton Keynes.

Aftercare tips
After the cure time, these simple habits help:
- Avoid strong solvents on or near the sealant
- Look over the glazing joints once a year
- Clean glass with a mild cleaner and a soft cloth
- Check the gutters above the glazing for debris
Look over the glazing joints every year or so. Spotting a crack early means a simpler fix, before water gets in.
Damp patches, drips and condensation along a joint are worth checking. The cause may be sealant or another part and we will find out which.
How we quote for glazing silicone
Your quote is based on your job. We look at:
- How much old sealant there is and how hard it is to remove
- The number of rooms or windows
- Any mould that needs treating
- The size of the job
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Access, such as stairs, a lift or height
- Whether it’s a home or a business
- Any previous sealing or DIY work
- Pictures of the joints, sent by email
To get a quote, phone 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. We’ll give you a clear price before any work starts.
What happens on the day
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from an hour or two to most of a day, depending on the size of the job and we leave things clean and tidy. Somewhere as small as Lavendon, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we agree the joints to be done.
- We cut away the failed silicone.
- We clean and prepare the joint.
- We apply and tool the new silicone.
- We inspect the work and test it where we can.
How to prepare
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work
- Let us know about parking restrictions

What we can’t put right
We will always be straight with you, so here’s what sealant cannot fix:
- A roof that has moved or dropped
- Leaks from the roof covering or flashing (a roofer’s job)
- Condensation trapped between two panes
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think.
Where we work in Lavendon
- Glass balustrade bases
- Rooflights
- Glass-to-glass joints
- Glass-to-frame joints
- Conservatory frames
- Shower screens
Different surfaces, different methods
Glass-to-frame joints
The sealant must stick to glass and frame alike. We use a glazing silicone suited to each.
Shower screens
Most shower screen leaks come from the wall or tray joint. We reseal both with anti-fungal silicone.
