About our glazing silicone in Grimsbury
Glass replacement isn’t something we do, and misting between panes means a failed sealed unit. What we do is the silicone around the glass and that is often where the water gets in. Common call-outs are for a quick top-up bead that didn’t last and mouldy sealant around glass panels, across glass-to-glass joints, rooflights and glass-to-frame joints.
Houses in smaller places like Grimsbury can stand more in the open than those in a built-up town. The mastic around frames on those walls tends to age faster.
Every job comes with a one-year guarantee, wherever you are in Oxfordshire.

The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours, depending on how many joints need doing. For a job in Grimsbury, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We find where water is getting in and check whether it’s a sealant joint.
- Old silicone is cut away from the glass and frame without scratching either.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- We apply a neutral-cure glazing silicone and tool it smooth.
- We check the joints and, where safe, run water over them.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Keep children and pets away from the work area
- Mention any parking rules near the property

Why act early in Grimsbury
A new conservatory roof is a big job. Where the water is getting in through sealant renewing the joint is the simpler fix. If it’s the roof itself, we will tell you. In an older home around Grimsbury, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or drop us an email.

Frames and glazing around Grimsbury
London and the South East are among the drier parts 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 Broughton Castle (about 3.4 miles south-west) nearby, there’s older building stock in the area around Grimsbury as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you look after a building such as St Leonard's Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Saint Leonard's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Common problems we fix in Grimsbury
New silicone over old silicone won’t bond. Many failed joints we see have been topped up rather than cut out, and water gets between the layers.
If you can see any of these, it’s time to have the joints looked at:
- Sealant that was laid over old silicone and failed
- Water getting into a conservatory at the joints
- Split or lifting silicone on glass
- Drips on the inside of a conservatory window
Letting a property close to Banbury station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows.
Questions to ask before booking
- Whether you can choose the colour
- What the cure time is
- What product goes in the joint
- How hidden problems are handled

Honest limits
We won’t take on work that will not last, so these are the limits:
- Leaks from the roof covering or flashing (a roofer’s job)
- A frame that needs repairing or replacing
- Structural problems with a conservatory roof
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly before booking.
What we seal
- Glass-to-glass joints
- Glass-to-frame joints
- Glass balustrade bases
- Rooflights
- Conservatory frames
- Shower screens
Aftercare tips
To keep the joints looking good and working properly:
- Clear the conservatory gutters regularly
- Open vents or windows to let moisture out
- Avoid strong solvents on or near the sealant
- Run a squeegee over the glass when you’re done
Gentle products are best near the sealant. Harsh solvents may damage the bead.
A leaking shower screen may not show at first. It can damage the floor or the ceiling below before you spot it.

Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
