When to call us in Anstey
UV light ages silicone, especially on conservatory roofs. Old silicone hardens, cracks and loses its grip to the glass and frame.
People generally contact us when they notice something like this:
- Leaks where conservatory glass meets the frame
- Black or yellowed silicone on glass joints
- Glazing silicone that has cracked or come away
- Shower screens leaking along the wall or tray
Managing a site like Anstey First School? Then larger buildings have plenty of frames, and the mastic around each one ages.
What to look for in a quote
- What the quote includes, VAT included or not
- How long the guarantee is
- Whether the sealant suits the joint

Glazing silicone in Anstey
Our work covers conservatory joints, rooflights and glass panels plus shower screens and the bases of glass balustrades. The old sealant comes out, the joint is cleaned and new silicone goes in. If you are dealing with silicone pulling away from the glass and failed sealant around rooflight glass, we can put it right.
Mastic can only go onto a dry, clean joint, so window work in Anstey is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Every job comes with our one-year guarantee, wherever you are in Hertfordshire.

Surface by surface
Glass-to-frame joints
Glass-to-frame joints need a sealant that bonds to both. We choose a product that suits both.
Shower screens
Black or peeling silicone on a screen lets water out. A full reseal sorts it.
Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
For landlords and businesses
We also work for property managers and facilities teams in Anstey and across Hertfordshire. Several sites can go on one quote.
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will give you a quote.
Why deal with it now?
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 will tell you if that’s not the case. In a small place like Anstey, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or drop us an email and we’ll talk you through it.

What we do, step by step
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes anything from an hour or two to most of a day, depending on the size of the job in most cases. Somewhere as small as Anstey, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at the glazing and agree which joints need resealing.
- Old sealant is removed from the glass and frame.
- The surfaces are cleaned with a suitable solvent.
- We apply and tool the new silicone.
- The joints are checked before we leave.
Getting ready for the visit
- Clear the area around the work
- Try not to wet indoor joints just before the visit
- Keep children and pets away from the work area

Anstey homes and the weather
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.
For an older house near a landmark such as Church of St George, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What affects the cost of glazing silicone
For a quick quote, just ask. What matters most is:
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
- The product the joint needs
- Access and height
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and agree the price before starting.
Asking for a quote
What to tell us when you ask for a quote:
- How we’d reach the joints
- The rough size of the job
- If someone has resealed it before
- Whether it’s a home or a business
Every job is quoted individually, so start by telling us what you need. Simply phone 0345 464 0079 or drop us an email and describe the job, and pictures are welcome.
Anstey questions
Do you cover smaller places like Anstey?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you cover Anstey for glazing silicone?
Yes. We work across London and the South East, and Anstey is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing, and we’ll give you a clear price.
Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in.
What sealant do you use on glazing?
Glass needs a sealant made for glazing. We use neutral-cure glazing silicone with anti-fungal products in bathrooms.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do you guarantee glazing sealant work?
Our 12-month guarantee applies on all our work.
