Windows and doors in Chichester
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 2.7 miles north-east) are a reminder that the area around Chichester 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.
Letting a property close to Chichester station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows. If you look after a building such as Lancastrian Infant School, its window and door frames need their mastic kept sound, just like a home’s.

About our glazing silicone in Chichester
Frameless shower screens rely on sealant to keep water in. The joint down the wall and the one along the tray are common leak points and both get fresh anti-fungal silicone. We work on glass-to-glass joints, conservatory frames and glass-to-frame joints, and the jobs we see most are sealant that was laid over old silicone and failed and split or lifting silicone on glass.
In a town like Chichester, the windows on the most exposed side of a house take the brunt of the rain, so the mastic there tends to fail first. It’s worth looking at every frame, not just the one that leaks.
Every job comes with a one-year guarantee, wherever you are in West Sussex.

DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Clear the conservatory gutters regularly
- Open vents or windows to let moisture out
- Clean glass with a mild cleaner and a soft cloth
- Look over the glazing joints once a year
Keep the new joints dry for as long as we advise. After that, clean glass with a mild cleaner.
Act on black or lifting silicone early. Peeling silicone lets water in behind and the leak gets worse.
How the visit works
There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes anything from an hour or two to most of a day, depending on the size of the job. For a job in Chichester, we need access to where the work is and somewhere nearby to park. For outside work, let us know about side access, gates and any upper-floor joints.
- First, we trace the leak and check it’s coming through a sealant joint.
- We cut out the failed silicone, taking care of the glass and frame.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- Glazing silicone suited to the joint is applied and tooled.
- We look over every joint and, where we can, test it with water.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Mention if the joints have been sealed before
- Move anything stored near the joints

Common problems we fix in Chichester
Silicone won’t bond to a dirty surface. Where the joint wasn’t cleaned and degreased the sealant may lift within a few years.
Keep an eye out for any of the following:
- Mouldy sealant around glass panels
- Leaks where conservatory glass meets the frame
- Rooflight joints letting water in
- Water tracking down the inner face of the glass
For an older house near a landmark such as Church of St Paul, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How the job changes by surface
Glass-to-frame joints
Old sealant is removed carefully from the glass and reseal with glazing silicone.
Rooflights
Rooflight glazing joints are cut out and renewed. Leaks from the roof itself need a roofer.
What affects the cost of glazing silicone
Your quote is based on your job. We take into account:
- Mould in or behind the old joints
- How much old sealant there is and how hard it is to remove
- The amount of work
- The type of sealant required
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Ask us for a quote and we will go through it with you.
What to tell us for a quote
Photos by email are helpful but not essential. Please mention:
- Whether it has been sealed before
- The type of property
- Where the property is
- What the problem is, such as mould, gaps, leaks or cracking
