Glazing silicone in Merston
Glazing joints need a sealant made for glass. Our applicators use neutral-cure glazing silicone, which suits glass and most frame materials, finished with a neat, even bead. If you have conservatory leaks at frame and glazing joints and water running down inside the glass, we can put it right.
Homes in small places like Merston often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
The work is covered for a year after we finish. If anything is not right with it, call 0345 464 0079 or email us.

For landlords and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.

Frames and glazing around Merston
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Goodwood House (about 3.5 miles north) are a reminder that the area around Merston 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.
For site and facilities teams at buildings such as North Mundham Primary School, the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as Church of St Giles, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Avoid scraping close to the bead
- Get a new leak looked at quickly
- Ventilate the conservatory to cut condensation
- Clear the conservatory gutters regularly
Use mild cleaners on and around the silicone. Harsh solvents may damage the bead.
Don’t leave lifting or mouldy silicone on glazing. Once it starts to peel, water gets behind it and the leak gets worse.
Why deal with it now?
A new conservatory roof is a big job. If the leak is a failed sealant joint, resealing is far simpler. If the roof is the problem, we’ll say so. In a small place like Merston, homes can be exposed to wind and rain, which finds any gap, 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, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Your questions about glazing silicone in Merston
Can you do glazing silicone in Merston?
Yes. Our work covers London and the South East, and Merston is part of that. Just call 0345 464 0079 or email us with a few details of the job, and we’ll send you a clear quote.
I let a flat near Chichester station. Can you help?
Yes. We work for landlords and agents as well as homeowners. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Can you work on commercial sites?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Is a special sealant needed for glass?
We pick a glazing silicone to suit the materials. Neutral-cure silicone is the usual choice.
Is it enough to run a bead over the old sealant?
A top-up rarely holds. Fresh silicone won’t bond to cured silicone, so we remove the old sealant and clean the joint.
Do you offer different sealant colours?
Yes. White, clear and grey are common, and other colours are available, and we’ll agree it with you first.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.

How the visit works
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. 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 Merston, 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.
- We check the finished joints and test with water where it’s safe.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Clear the area around the work
- Keep pets and children clear of the area while we work

Related advice
Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What we’re called out for in Merston
New silicone over old silicone will not bond. Plenty of leaks come from a quick top-up over the old bead leaving a path for water.
Most people get in touch when they notice something like this:
- Silicone pulling away from the glass
- Drips on the inside of a conservatory window
- Glass-to-glass joints that have split
- Failed sealant around rooflight glass
Rented homes near Chichester station change hands often, and leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.
