Glazing & conservatory sealant in Compton, Hampshire
Our applicators work in Compton on glazing silicone for conservatories, rooflights, glass panels and shower screens. Old sealant removed completely, joints prepared properly and a 12-month guarantee.
- Failed sealant around rooflight glass
- Leaks where conservatory glass meets the frame
- Mouldy sealant around glass panels
Why act early in Compton
Topping up old silicone can look like a fix, but silicone doesn’t stick to silicone and water soon finds its way back. Cutting out and resealing properly lasts. Where a wall is exposed, as many are in small places like Compton, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or email us for an honest opinion and a quote.

Glazing silicone for homes and businesses in Compton
Frameless shower screens rely on sealant to keep water in. Leaks normally come from the wall joint or the tray joint, and we reseal both. We are often asked to deal with cracked silicone between glass panels and water getting into a conservatory at the joints, on glass-to-frame joints, conservatory frames and glass-to-glass joints.
Somewhere as small as Compton, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Big or small, it’s backed by our one-year guarantee.

What else we do in Compton
Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Compton homes and the weather
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near Shawford station change hands often, and glazing joints are worth checking at the end of a tenancy, before a small leak grows. Schools such as Compton All Saints Church of England Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as Church of All Saints, the joint between an old wall and a newer frame is generally the first place rain gets in.

What the job involves on each surface
Glass balustrade bases
Balustrade bases are exposed outdoors. A sound sealant joint keeps them tidy and dry.
Glass-to-frame joints
Old sealant is removed carefully from the glass before new glazing silicone goes in.
What affects the quote in Compton
The price is agreed before any work begins. It takes into account:
- Mould in or behind the old joints
- How many rooms, windows or areas are involved
- The size of the job
- Whether old sealant or filler has to be cut out
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What we need to know
What to tell us when you ask for a quote:
- If someone has resealed it before
- How we’d reach the joints
- Where the job is, and your postcode
- A few photos by email, if you can
For a quick quote, get us on the phone, or email us if that is easier. Describe what needs sealing and we’ll talk you through the work.
How the visit works
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes anything from an hour or two to most of a day, depending on the size of the job. Somewhere as small as Compton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We trace the leak and confirm it’s a sealant joint.
- We remove the old sealant carefully.
- The joint is cleaned and degreased.
- A neutral-cure glazing silicone is applied and tooled.
- We check the finished joints and test with water where it’s safe.
How to prepare
- Let us know if you’ve seen damp or leaks
- Mention any sign-in or site rules at work premises
- Keep children and pets away from the work area
How to get a quote
Asking for a quote is easy: let us know the job and the location. A few photos by email make the job easier to understand.

What sealant work can’t fix
A few problems are outside what sealant work can do:
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- A frame that needs repairing or replacing
- Structural problems with a conservatory roof
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think.
Surfaces we seal
- Glass-to-frame joints
- Glass balustrade bases
- Conservatory frames
- Shower screens
- Glass-to-glass joints
- Rooflights
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Open vents or windows to let moisture out
- Clean glass with a mild cleaner and a soft cloth
- Do not leave a drip for the next storm
- Keep harsh solvents off the silicone
Keep the new joints dry for as long as we advise so the silicone can set properly. From then on, a mild glass cleaner is all it needs.
Act on black or lifting silicone early. Once it starts to peel, water gets behind it and the leak gets worse.
