Glazing & conservatory sealant in Downley, Buckinghamshire
Glazing silicone for Downley, by sealant specialists with 20+ years’ experience. 180+ five-star Google reviews and a 4.9 rating.
- Leaks where conservatory glass meets the frame
- Water tracking down the inner face of the glass
- Water escaping where a screen meets the wall
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Keep harsh solvents off the silicone
- Clear the conservatory gutters regularly
- Don’t leave a drip for the next storm
- Look over the glazing joints once a year
Use mild cleaners on and around the silicone. Strong solvents can soften or mark it.
Cracked glazing silicone means the joint has failed. Resealing now is a small job compared with fixing water damage later.
How we handle glazing silicone in Downley
Glass replacement isn’t something we do, and misting between panes means a failed sealed unit. Our work is the sealant joints and that’s often where the water gets in. Common call-outs are for conservatory leaks at frame and glazing joints and sealant that was laid over old silicone and failed, on shower screens, glass-to-glass joints and rooflights.
Around Downley, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

Downley: your questions answered
Is Downley within the area you cover?
Yes, Downley is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you do glazing silicone in Downley?
Yes. We work across London and the South East, and Downley is part of that. Just ring 0345 464 0079 or email us with a few details of the job.
Is it enough to run a bead over the old sealant?
New silicone won’t bond to old silicone and water gets between the layers. We cut out the old sealant first.
Can you fix a leaking conservatory?
It depends on the cause. Sealant joints we can renew, but roof panels and structural problems need a conservatory specialist or roofer.
Is balustrade sealant something you do?
Yes, where the base is finished with sealant. Send us photos and we will take a look when you phone 0345 464 0079 or send us an email.
What should I tell you?
Tell us what needs doing and where, with photos by email if possible. We’ll ask anything else we need to know.
Will the old sealant be removed?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Do you guarantee glazing sealant work?
Every job comes with our one-year guarantee.
What we’re called out for in Downley
On shower screens, constant water and cleaning products wear silicone. Mould grows into the bead and the edges begin to peel.
The most common problems we see are:
- Leaks where conservatory glass meets the frame
- Failed sealant around rooflight glass
- Glass-to-glass joints that have split
- Water escaping where a screen meets the wall
Managing a site like The Downley School? Then larger buildings have plenty of frames, and the mastic around each one ages.
What your quote should include
- How much experience the applicator has
- Whether you can choose the colour
- What product goes in the joint

Different surfaces, different methods
Glass balustrade bases
The base joint is cut out and resealed. Glass fitting is a separate trade.
Conservatory frames
Exposed frame joints wear with the weather. Renewed sealant keeps water out.
What happens on the day
When we arrive, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. The work generally takes a few hours for most jobs. Somewhere as small as Downley, 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.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Keep pets and children clear of the area while we work
- Let us know about parking restrictions

Should I try it myself first?
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 fails, we can still redo it.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
For landlords and businesses
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
For anyone letting property in or around Downley, jobs at different addresses can go on one quote. Send us the addresses and the work at each, and pictures by email help.
What sealant work can’t fix
We’ll always be straight with you, so here’s what sealant cannot fix:
- A frame that needs repairing or replacing
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- Structural problems with a conservatory roof
If in doubt, call 0345 464 0079 or email us and we will say what we think before booking.

Windows and doors in Downley
With historic houses such as Hughenden Manor (about 0.8 miles east) nearby, there’s older building stock in the area around Downley as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near High Wycombe station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. Homes close to St. James the Great include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.
