- New silicone smeared over old sealant
- Shower screens leaking along the wall or tray
- Rooflight joints letting water in
Do you need glazing silicone in Sleapshyde?
The wrong sealant is a common cause. Not every silicone sticks properly to glass, and acetoxy types can attack some frame materials.
Any of these means the joints need attention:
- Conservatory leaks at frame and glazing joints
- Leaks from the base of a shower screen
- Glazing silicone that has cracked or come away
- Mouldy sealant around glass panels
In the older streets around Church of St Mark, the joint between an old wall and a newer frame is normally the first place rain gets in.
Questions to ask before booking
- Which colour the sealant will be
- What insurance they hold
- What the cure time is
- What happens if they find a problem under the old sealant
About our glazing silicone in Sleapshyde
We renew glazing silicone on conservatories, rooflights and glass panels, as well as frameless shower screens and glass balustrade bases. The old sealant comes out, the joint is cleaned and new silicone goes in. We work on glass balustrade bases, glass-to-glass joints and rooflights, and common reasons people get in touch are mouldy sealant around glass panels and leaks from the base of a shower screen.
Homes in small places like Sleapshyde often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
Your job is guaranteed for a year, as with all our work.

What glazing silicone looks like in Sleapshyde
Sleapshyde is part of Hatfield, one of the post-war new towns. With many homes from the post-war decades, replacement windows and doors are common. That mastic ages as well, and sills and frame heads are where leaks start. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Colney Heath Junior Mixed Infant and Nursery School, larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Welham Green station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

Why it’s worth doing now in Sleapshyde
Leaks get worse, not better. Left, water can mark floors, damage plaster and rot timber, so it pays to deal with it early. Where a wall is exposed, as many are in small places like Sleapshyde, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and send you a clear quote before we start.

FAQs for Sleapshyde
Do you cover smaller places like Sleapshyde?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do older homes in Sleapshyde need their sealant replacing?
If it hasn’t been replaced for some years, it’s normally worth it. Sealant is a maintenance item: how long it lasts depends on use, cleaning and exposure, and many homes in Sleapshyde may already be on their second or third set.
Are you insured?
Yes. We are fully insured.
Do you seal glass balustrade bases?
Yes. The sealant joint at the base can be renewed. We do not install or replace the glass.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
What guarantee do I get?
There’s a 12-month guarantee on every job.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
What sealant work cannot fix
Some problems need a builder, plumber or other trade rather than us:
- A broken pane or roof panel
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- Frames that have decayed or split
If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer.

Advice
Can I do it myself?
Some jobs are best left to a professional: 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. 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.
