How we quote for glazing silicone
Some jobs are bigger than they look, and some smaller. The main factors:
- The number of rooms or windows
- Access and height
- The old material and how stubborn it is
- The size of the job
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Asking for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- If someone has resealed it before
- If it’s domestic, commercial or a hotel
- The address or postcode of the job
- Photos by email, if that’s easy
Getting a quote is simple: let us know what needs doing and where. Photos by email help us understand the job, and we’ll take it from there.
About our glazing silicone in Fleet Marston
Not every silicone suits glass. Our applicators use neutral-cure glazing silicone, which suits glass and most frame materials, and we tool it to a neat, even finish. If you are dealing with drips on the inside of a conservatory window and conservatory leaks at frame and glazing joints, we can help.
Mastic can only go onto a dry, clean joint, so window work in Fleet Marston is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
You get a one-year guarantee, the same in Fleet Marston as everywhere else we work.

What we do, step by step
When we arrive, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before work begins. Most jobs take a few hours for most jobs. Somewhere as small as Fleet Marston, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we trace the leak and check it’s coming through a sealant joint.
- The old sealant is removed from the glass and frame without scratching them.
- The glass and frame are cleaned and degreased.
- 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 sign-in or site rules at work premises

Fleet Marston homes and the weather
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 Waddesdon Manor (about 3.1 miles west) nearby, there’s older building stock in the area around Fleet Marston as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
For landlords with property near Aylesbury Vale Parkway station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. For an older house near a landmark such as St Mary's Church, the joint between an old wall and a newer frame is normally the first place rain gets in.

Why deal with it now?
A leaking joint will not fix itself. Water can damage frames, walls, flooring and furniture, so it pays to deal with it early. Around Fleet Marston, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, call 0345 464 0079 or send us an email for an honest opinion and a quote.

What the job involves on each surface
Shower screens
Frameless screens rely on silicone at the base and wall. We reseal without scratching the glass.
Rooflights
Rooflights get the full force of the weather. The sealant around the glass and frame wears faster than most.
What sealant work cannot fix
Some problems need a builder, plumber or other trade rather than us:
- Condensation trapped between two panes
- A roof that has moved or dropped
- Leaks from the roof covering or flashing (a roofer’s job)
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.
Surfaces we seal
- Shower screens
- Glass-to-glass joints
- Rooflights
- Glass balustrade bases

Common problems we fix in Fleet Marston
Sealant laid over old sealant does not last. Plenty of leaks come from a quick top-up over the old bead, and water gets between the layers.
Look out for these signs:
- Water running down inside the glass
- Failed sealant around rooflight glass
- Black or yellowed silicone on glass joints
- Shower screens leaking along the wall or tray
If you look after a building such as Green Ridge Primary Academy, the mastic around its windows and doors needs looking after like any other building’s.
