Landlord and commercial work in Highbridge
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
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.
Glazing silicone in Highbridge, done properly
Conservatory leaks often start at a sealant joint at the glass-to-frame or frame-to-wall joints. We find the joint that’s letting water in and renew it and tell you plainly if the cause is something else. If you have shower screens leaking along the wall or tray and silicone pulling away from the glass, we can help.
Around Highbridge, 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.
Big or small, you get the same one-year guarantee in Highbridge and across Hampshire.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Check the silicone on glass every year or so
- Ventilate the conservatory to cut condensation
- Keep harsh solvents off the silicone
- Squeegee the shower screen after each use
Keep conservatory gutters clear so water does not back up against the seals. Overflowing gutters can cause leaks of their own.
A leaking shower screen may not show at first. Water can soak into the floor or reach the room below before you spot it.
What sealant work can’t fix
A few problems are outside what sealant work can do:
- Leaks from the roof covering or flashing (a roofer’s job)
- A sagging or failing conservatory roof
- Condensation trapped between two panes

Why act early in Highbridge
You do not need new glazing because the sealant has gone. If the glass and frame are sound, new silicone is often all it takes, and we’ll tell you if that is not the case. Older cottages and farmhouses around Highbridge can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

FAQs for Highbridge
Can you help a landlord with a rental near Eastleigh station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Can you do glazing silicone in Highbridge?
Yes. We work across London and the South East, and Highbridge is part of that. You can call 0345 464 0079 or email us and tell us what needs doing.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Is the work guaranteed?
There’s a 12-month guarantee on every job, glazing sealant included.
Do you replace glass?
No. Misting between panes means the sealed unit has failed, and a glazier needs to replace it.
Is it possible to redo the silicone on a shower screen?
Yes. We cut out the old silicone and reseal the glass-to-wall and glass-to-tray joints.
Can you just put new silicone over the old?
Many leaks we see come from exactly that. A proper job means cutting out, cleaning and resealing.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before resealing.
Glazing silicone in Highbridge: local notes
With historic houses such as South Stoneham House (about 4.2 miles south-west) nearby, there’s older building stock in the area around Highbridge as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Managing a site like Colden Common Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as St Mary's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For landlords with property near Eastleigh station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
What affects the cost of glazing silicone
For a quick quote, just ask. The main things that affect it are:
- How much old sealant there is and how hard it is to remove
- The amount of work
- Whether the work is at height
- Which sealant suits the joint
Leaving a failed joint normally makes the job bigger, not smaller. If you are unsure, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- A few pictures by email, if you can
- How we’d reach the joints
- Any previous sealing or DIY work
- The type of property
For glazing silicone in Highbridge, ring 0345 464 0079 or email us. A short description of the job and where it is helps us quote, and you will get a clear quote before any work starts.
The process
We keep the work tidy and contained to the area we are working on, so you can carry on as normal. Expect the work to take a few hours for most jobs, and we explain the cure time before we leave. Somewhere as small as Highbridge, 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.
- The failed silicone is cut out without marking the glass or frame.
- We clean the glass and frame so the new silicone bonds.
- We lay the new bead and tool it smooth.
- Each joint is checked and, where possible, water-tested.
Before we arrive
- Move anything stored near the joints
- Keep pets and children clear of the area while we work
- Tell us about any previous sealing or DIY attempts
