- Water escaping where a screen meets the wall
How it works
You do not need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the job takes a few hours, depending on how many joints need doing in most cases. Somewhere as small as Lower Assendon, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- We clean the glass and frame so the new silicone bonds.
- We lay the new bead and tool it smooth.
- Each joint is checked and, where possible, water-tested.
Before we arrive
- Let us know about earlier repairs to the joints
- Where the joints are inside, avoid wetting them before we arrive
- Keep pets and children clear of the area while we work
How to get a quote
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we will talk you through the work and give you a clear price.
Related advice
Glazing silicone in Lower Assendon
Glazing joints need a sealant made for glass. Our applicators use neutral-cure glazing silicone that’s suited to glass and the frame, and we tool it to a neat, even finish. If you have cracked silicone between glass panels and conservatory leaks at frame and glazing joints, we can put it right, whatever the surface.
In a village or hamlet like Lower Assendon, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
There’s a 12-month guarantee on every job.

When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Water coming through the roof rather than a sealant joint
- Rotten or badly damaged frames
- Condensation trapped between two panes

People usually contact us when they notice something like this:
- Black or yellowed silicone on glass joints
- Split or lifting silicone on glass

Lower Assendon homes and the weather
Historic houses like Greys Court (about 1.6 miles south-west) are a reminder that the area around Lower Assendon 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. 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.
Managing a site like Rupert House School? Then larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Henley-On-Thames station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

Leave it or put it right?
Topping up old silicone can look like a fix, but new silicone won’t bond to old, and the leak generally returns. Cutting out and resealing properly lasts. Around Lower Assendon, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Surface by surface
Rooflights
Rooflight glazing joints are cut out and renewed. Leaks from the roof itself need a roofer.
Glass-to-glass joints
Frameless glass corners and panels are joined with silicone. We reseal with a suitable glazing silicone.
Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
