Glazing & conservatory sealant in California, Wokingham
Glazing silicone across California and nearby, with every bit of old sealant taken out first and a 12-month guarantee.
- Cracked silicone between glass panels
- Water escaping where a screen meets the wall
- Leaking glazing joints on a rooflight
What we do, step by step
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the job takes anything from an hour or two to most of a day, depending on the size of the job in most cases. Somewhere as small as California, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we trace the leak and check it’s coming through 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.
- New glazing silicone goes in and is tooled to a neat finish.
- We look over every joint and, where we can, test it with water.
Getting ready for the visit
- Mention any parking rules near the property
- Keep children and pets away from the work area
- Clear the area around the work

Glazing silicone for homes and businesses in California
Conservatory leaks often start at a sealant joint at the glass-to-frame or frame-to-wall joints. We find the joint that’s letting water in and renew it and tell you plainly if the cause is something else. If you have leaks from the base of a shower screen and cracked silicone between glass panels, we can help, on glass balustrade bases, shower screens and rooflights alike.
Mastic can only go onto a dry, clean joint, so window work in California is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Every job comes with our 12-month guarantee, wherever you are in Wokingham.

Why it’s worth doing now in California
A leaking joint will not fix itself. Water can damage frames, walls, flooring and furniture so early action saves a bigger repair. Older cottages and farmhouses around California can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.
Why California clients choose us
- Sanitary silicone with an anti-fungal additive in wet areas
- A choice of colours where the product allows

- Old sealant always removed completely

California homes and the weather
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to Church of St James include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Rented homes near Crowthorne station change hands often, and leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.
California is about 3 miles south-west of Wokingham, in Wokingham. Whether you are in the middle of California or further out, glazing silicone is available for homes and businesses alike, from flats and houses to offices and hotels. California is one of 35 places in Wokingham where we work for glazing silicone. Reading is on our list too, around 7 miles away.
Every address in RG40 is covered for glazing silicone, from the main roads to the quietest streets. We cover properties on Warren Lane, White Horse Lane and Fernbank and the roads around them.

What affects the cost of glazing silicone
Your quote is based on your job. We take into account:
- How many areas need sealing
- Whether the work is at height
- The size of the job
- The old material and how stubborn it is
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.
Helping us quote
When you call or email, it’s useful to know:
- How many joints, rooms or windows are involved
- A few pictures by email, if you can
- Any access issues, like height or stairs
- If someone has resealed it before
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.
When it isn’t the sealant
Before booking, it’s worth knowing the limits:
- A frame that needs repairing or replacing

Where we work in California
- Conservatory frames
- Glass balustrade bases
- Glass-to-frame joints
- Rooflights
- Shower screens
- Glass-to-glass joints
Should I try it myself first?
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, then guaranteed for a year.
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.
What we are called out for in California
Heat and cold make glass and frames move at different rates. In time, the sealant splits or pulls away.
If you can see any of these, it’s time to have the joints looked at:
- Drips on the inside of a conservatory window
- Water getting into a conservatory at the joints
- Failed sealant around rooflight glass
- Stained, discoloured glazing silicone
For site and facilities teams at buildings such as Gorse Ride Junior School, the mastic around its windows and doors needs looking after like any other building’s.
Questions to ask before you book
- Which colour the sealant will be
- How much experience the applicator has
- Whether VAT is included
- What guarantee comes with the work
