Glazing silicone in Eastergate, done properly
We work across Eastergate on glazing joints for homes and businesses. From conservatories to shower screens, it’s the same careful method. If you are dealing with leaks where conservatory glass meets the frame and sealant that was laid over old silicone and failed, we can put it right.
Mastic can only go onto a dry, clean joint, so window work in Eastergate is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Every job is covered by a one-year guarantee.

Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Stick to mild cleaners on glass
- Clear the conservatory gutters regularly
- Avoid strong solvents on or near the sealant
- Look over the glazing joints once a year
Keep conservatory gutters clear, so water drains away from the joints. Overflowing gutters can cause leaks of their own.
Damp patches, drips and condensation along a joint are worth checking. The cause may be sealant or another part, and we’ll tell you which.
Why deal with it now?
A new conservatory roof is a big job. If the leak is a failed sealant joint renewing the joint is the simpler fix. If it’s the roof itself, we will tell you. In a small place like Eastergate, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
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.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
How it works
All our tools and materials come with us in the van. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take anything from an hour or two to most of a day, depending on the size of the job. Somewhere as small as Eastergate, 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.
- We remove the old sealant carefully.
- The joint is cleaned and degreased.
- 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 stairs, lifts or work at height
- For business premises, tell us about site rules or sign-in
- Tell us if parking is tricky

Glazing silicone in Eastergate: local notes
Rainfall in the South East is lower than in much 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 Goodwood House (about 4.2 miles north-west) nearby, there’s older building stock in the area around Eastergate 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.
If you look after a building such as Eastergate CofE Primary School, the mastic around its windows and doors needs looking after like any other building’s. If you live in an older home near St George's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Rented homes near Barnham station change hands often, and glazing joints are worth checking at the end of a tenancy, before a small leak grows.
