Glazing & conservatory sealant in Gundleton, Hampshire
Glazing silicone for Gundleton and the surrounding area: careful preparation, the right product and tidy work. Call for a quick quote.
- Conservatory leaks at frame and glazing joints
- Water escaping where a screen meets the wall
- Cracked silicone between glass panels
Should I try it myself first?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
Glazing silicone in Gundleton
We don’t replace glass and a misted double-glazed unit needs a glazier. What we do is the silicone around the glass, which is where many leaks start. We work on shower screens, conservatory frames and rooflights, and the jobs we see most are sealant that was laid over old silicone and failed and conservatory leaks at frame and glazing joints.
Mastic can only go onto a dry, clean joint, so window work in Gundleton is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
You’re covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

Gundleton homes and the weather
Historic houses like Hinton Ampner House (about 4 miles south) are a reminder that the area around Gundleton has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s 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.
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.
Gundleton is about 7 miles south-west of Alton, in Hampshire. Across the SO24 area, our applicators can take on glazing silicone. Gundleton is one of 683 towns and villages in Hampshire we cover for glazing silicone. We also work in Southampton, around 17 miles away.

Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Keep air moving in the conservatory
- Clear the conservatory gutters regularly
- Wipe the screen down after showering
- Use a gentle glass cleaner and a soft cloth
Gentle products are best near the sealant. Harsh solvents may damage the bead.
Conservatory leaks rarely stay small. Water runs along frames and down walls, so get it looked at when you first see it.
What we do, step by step
The work is kept neat and contained to the area we are working on, so you can carry on as normal. The job usually takes anything from an hour or two to most of a day, depending on the size of the job, and we explain the cure time before we leave. In a small place like Gundleton, access is normally the main thing to plan. 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.
- 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.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Keep children and pets away from the work area
- Tell us about any previous sealing or DIY attempts

Advice
Why it’s worth doing now in Gundleton
Resealing can’t fix a failed unit or a cracked panel. We’ll tell you that rather than seal it anyway and point you to a glazier or roofer. In a small place like Gundleton, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
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 we need extra access for height. We take all of that into account in your quote.
Why us?
- A sealant colour to suit the surroundings
- Experience in homes, commercial sites and hotels
- Trusted Arbo and Everbuild sealants
- Fully insured
What we are called out for in Gundleton
On shower screens, constant water and cleaning products wear silicone. Mould gets into it and the joint starts to lift.
Keep an eye out for these signs:
- Shower screens leaking along the wall or tray
- Leaks where conservatory glass meets the frame
- Silicone pulling away from the glass
- New silicone smeared over old sealant
If you look after a building such as Perins School, the mastic around its windows and doors needs looking after like any other building’s.
Before booking anyone
- Which colour the sealant will be
- Who turns up on the day
- How the joint is cleaned and prepared
- How long to leave it before use
What affects the cost of glazing silicone
You will get a clear quote before work begins. It takes into account:
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
- Whether the work is at height
- When we can work, for business premises
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or email us and we’ll give you an honest view and a quote.
