Horndean: your questions answered
Do you work for landlords with property near Rowlands Castle station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Is Horndean in your area for glazing silicone?
Yes. Our work covers London and the South East, and Horndean is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing, and we’ll give you a clear price.
Is it enough to run a bead over the old sealant?
New silicone won’t bond to old silicone, so a top-up soon lets water through. The old bead always comes out first.
Do you replace glass?
That’s not something we do. Misting between panes means the sealed unit has failed and needs replacing by a glazier.
What information do you need?
The location, the problem and the rough size of the job. If you can, email a few photos.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Is the work guaranteed?
There’s a 12-month guarantee on every job, glazing sealant included.
Are you insured?
Yes. Full insurance covers our work.
About our glazing silicone in Horndean
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. If you have water running down inside the glass and split or lifting silicone on glass, we can put it right.
In a town like Horndean, older houses sit alongside newer estates, with windows of every age. All of them depend on a sound bead of mastic between frame and wall.
All of our work is guaranteed for twelve months.

If in doubt, call 0345 464 0079 or email us and we’ll say what we think before you book.

What affects the cost of glazing silicone
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How many areas need sealing
- Mould in or behind the old joints
- Whether the work is at height
- The amount of work
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.
Helping us quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Where the job is, and your postcode
- Access, such as stairs, a lift or height
- A few photos by email, if you can
- Roughly how big the job is
We don’t publish a price list. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or email us.
Why it’s worth doing now in Horndean
Glazing joints need a sealant made for the job. A general-purpose tube may not bond well or may react with the frame, so we use neutral-cure glazing silicone. In Horndean, as anywhere, most leaks start as a small gap in a joint, and they’re far easier to fix early.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll go through it with you.
Why us?
- A choice of colours where the product allows
- Full insurance on every job
- Sealant colour chosen to suit

Horndean homes and the weather
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Warblington Castle (about 4.8 miles south-east) nearby, there’s older building stock in the area around Horndean 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.
If you look after a building such as Horndean Technology College, larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Rowlands Castle station, glazing joints are worth checking at the end of a tenancy, before a small leak grows. If you live in an older home near Saint Wilfrid's, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What we do, step by step

Parking in a town like Horndean is usually straightforward, but tell us if there’s a driveway or any restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- First, we trace the leak and check it’s coming through a sealant joint.
- We cut out the failed silicone, taking care of the glass and frame.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- Glazing silicone suited to the joint is applied and tooled.
- The finished joints are checked and, where it’s safe, tested with water.

Advice
For landlords and businesses
Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Surface by surface
Conservatory frames
Exposed frame joints wear with the weather. A fresh bead seals them again.
Glass balustrade bases
We reseal the joint where the glass meets the base channel. Glass fitting is a separate trade.
DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
