Frameless glass corners and panels are joined with silicone. We renew it with a clear or matching glazing silicone.
Rooflights
Rooflight glazing joints are cut out and renewed. Leaks from the roof itself need a roofer.
Glazing silicone for homes and businesses in Harestock
Not every silicone suits glass. Our applicators use neutral-cure glazing silicone that’s suited to glass and the frame, and we tool it to a neat, even finish. If you have shower screens leaking along the wall or tray and mouldy sealant around glass panels, we can put it right.
Homes around Harestock range from older properties to newer houses, and their windows range just as widely. Each frame material needs the right sealant against the right wall.
You are covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or drop us an email.

Windows and doors in Harestock
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Winchester station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. In the older streets around Saint Barnabas, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Your questions about glazing silicone in Harestock
Can you do glazing silicone in Harestock?
Yes, Harestock is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and let us know what needs doing, and we will send you a clear quote.
Is Harestock within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
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.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Do you work for hotels and businesses?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
How long does the job take?
A typical job takes anything from an hour or two to most of a day, depending on the size of the job. Your quote will say how long we expect yours to take.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
I’m a tenant. Can you help?
Yes. Check with your landlord; we can send the quote to them too.
Leave it or put it right?
A leaking joint won’t fix itself. Water can damage frames, walls, flooring and furniture so early action saves a bigger repair. In a smaller place like Harestock, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or email us and we will give you an honest view and a quote.

Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
How we quote for glazing silicone
Every job gets its own quote. These are the things that affect it:
- Mould in or behind the old joints
- The number of rooms or windows
- How much old sealant there is and how hard it is to remove
- How easy the joints are to reach
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Helping us quote
To help us quote quickly, let us know:
- Roughly how big the job is
- If it’s domestic, commercial or a hotel
- Where the job is, and your postcode
- Any previous sealing or DIY work
For a quick quote, get us on the phone, or email us if that’s easier. Describe what needs sealing and we’ll talk you through the work and send you a clear quote.
What we do, step by step
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes anything from an hour or two to most of a day, depending on the size of the job. In a smaller place like Harestock, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- First we agree the joints to be done.
- We cut away the failed silicone.
- We clean and prepare the joint.
- We apply and tool the new silicone.
- We inspect the work and test it where we can.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Mention any sign-in or site rules at work premises
- Tell us about any water getting in

Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. When it suits you, phone 0345 464 0079 or drop us an email.

When to call us in Harestock
UV light ages silicone, especially on conservatory roofs. Old silicone hardens, cracks and loses its grip to the glass and frame.
Any of these means the joints need attention:
- Failed joints on frameless glass
- Stained, discoloured glazing silicone
- Water getting into a conservatory at the joints
- Drips on the inside of a conservatory window
For site and facilities teams at buildings such as Harestock Primary School, the mastic around its windows and doors needs looking after like any other building’s.
