Glazing silicone in Wendover Dean
We do not replace glass, and misting between panes means a failed sealed unit. What we do is the silicone around the glass, which is where many leaks start. We work on rooflights, glass balustrade bases and shower screens, and the jobs we see most are new silicone smeared over old sealant and water tracking down the inner face of the glass.
Mastic can only go onto a dry, clean joint, so window work in Wendover Dean is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or drop us an email.

Work for landlords, hotels and businesses
We also work for property managers and facilities teams in Wendover Dean and across Buckinghamshire. We can quote a run of properties together, and we are fully insured.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
How the job changes by surface
Glass-to-frame joints
The sealant must stick to glass and frame alike. We choose a product that suits both.
Glass-to-glass joints
Frameless glass corners and panels are joined with silicone. We reseal with a suitable glazing silicone.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Act on drips or damp patches early
- Open vents or windows to let moisture out
- Keep scrapers and blades away from the silicone
- Look over the glazing joints once a year
Look over the glazing joints every year or so. Catching a split early keeps the repair small.
A small conservatory leak soon spreads. Water runs along frames and down walls, so get it looked at when you first see it.
What happens on the day
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take anything from an hour or two to most of a day, depending on the size of the job. Somewhere as small as Wendover Dean, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at the glazing and agree which joints need resealing.
- We cut away the failed silicone.
- The surfaces are cleaned with a suitable solvent.
- New glazing silicone goes in and is finished neatly.
- We inspect the work and test it where we can.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Let us know about stairs, lifts or work at height
- Where the joints are inside, avoid wetting them before we arrive
Ask for a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email pictures if that is easy.

How we quote for glazing silicone
Some jobs are bigger than they look, and some smaller. The main factors:

- The size of the job

Asking for a quote
What to tell us when you ask for a quote:
- What the problem is, such as mould, gaps, leaks or cracking
- Photos by email, if that is easy
- How many joints, rooms or windows are involved
- Whether it’s a home or a business
Asking for a quote is easy: tell us what needs doing and where and its rough size. Photos by email help us understand the job, and we will come back to you with a quote.
What we cannot put right
We’ll always be straight with you, so here’s what new sealant won’t do:
- Leaks from the roof covering or flashing (a roofer’s job)
- A sealed unit that has misted inside
- Frames that have decayed or split
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.
What we seal
- Glass balustrade bases
- Shower screens
- Glass-to-frame joints
- Conservatory frames
- Rooflights

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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 doesn’t work out, we can still put it right.

Can a conservatory leak be sealed?
It depends on the cause. Sealant joints we can renew, but roof panels and structural problems need a conservatory specialist or roofer.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and you will get one quote.
Can you match the sealant colour?
Usually, yes. White, clear and grey are common, and other colours are available for many products, and we will agree it with you first.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.

Yes, it’s a common job. The screen is resealed with anti-fungal silicone made for wet areas.
