How we handle glazing silicone in Leverstock Green
Glazing joints need a sealant made for glass. We use a neutral-cure glazing silicone that’s suited to glass and the frame, finished with a neat, even bead. If you’re dealing with water getting into a conservatory at the joints and glazing silicone that has cracked or come away, we can put it right, on rooflights, glass balustrade bases and glass-to-frame joints alike.
In smaller places like Leverstock Green, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.
All our work comes with a 12-month guarantee, wherever you are in Hertfordshire.

DIY versus a professional finish
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.
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.
When to call us in Leverstock Green
Sunlight breaks sealant down, especially on conservatory roofs. It goes brittle, cracks and stops sticking to the glass and frame.
Most people get in touch after spotting one of these:
- Glass-to-glass joints that have split
- Sealant that was laid over old silicone and failed
- Leaks from the base of a shower screen
- Water running down inside the glass
If you live in an older home near Church of Holy Trinity, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Why deal with it now?
Silicone around glazing needs the right product. General-purpose sealant from a DIY shop may not suit glass or the frame, so we use neutral-cure glazing silicone. Homes in smaller places like Leverstock Green can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Combining jobs into one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.

Leverstock Green homes and the weather
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. Historic houses like Batchwood Hall (about 3.5 miles east) are a reminder that the area around Leverstock Green has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For site and facilities teams at buildings such as Leverstock Green Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Apsley station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

What the job involves on each surface
Conservatory frames
Leaks often start where the frame meets the wall. We cut out the old sealant and reseal.
Glass-to-frame joints
Silicone at the glass edge seals it into the frame. When it splits, water can get into the frame.

Your questions about glazing silicone in Leverstock Green
Is it worth replacing old sealant in an older home in Leverstock Green?
Usually, yes, if it’s cracked, shrunk, mouldy or coming away. New sealant will not stick to old, so the old bead has to come out completely first.
Can you help a landlord with a rental near Apsley station?
Yes. We work for letting agents and landlords as well as householders, and several properties can go on one quote. You can phone 0345 464 0079 or email us with the details for a clear quote.
Do you offer different sealant colours?
We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.
Is there any odour?
Possibly a little. It fades as the sealant cures.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do you reseal glass shower screens?
Yes, it’s a common job. We use anti-fungal silicone made for wet areas.
Is a special sealant needed for glass?
A glazing-grade silicone is best. Ours is a neutral-cure glazing silicone with anti-fungal products in bathrooms.
