Glazing silicone in Howlett End
We do not replace glass and a misted double-glazed unit needs a glazier. Our work is the sealant joints, which is where many leaks start. We work on shower screens, glass-to-glass joints and rooflights, and the jobs we see most are conservatory leaks at frame and glazing joints and leaks from the base of a shower screen.
Mastic can only go onto a dry, clean joint, so window work in Howlett End is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Howlett End homes and the weather
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Horham Hall (about 3.2 miles south) are a reminder that the area around Howlett End has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Schools such as Wimbish Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. Letting a property close to Newport (Essex) station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Why deal with it now?
Replacing a conservatory roof is major work. Where the water is getting in through sealant renewing the joint is the simpler fix. If the roof is the problem, we’ll say so. In a small place like Howlett End, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. We give a clear quote before we start, so you know where you stand.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

These are the problems we’re asked about most:
- Cracked silicone between glass panels
- Mouldy sealant around glass panels
- Water escaping where a screen meets the wall
- Glazing silicone that has cracked or come away

Keeping the joints in good condition
After the cure time, these simple habits help:
- Wipe the screen down after showering
- Use a gentle glass cleaner and a soft cloth
- Get a new leak looked at quickly
- Keep conservatory gutters clear of leaves
Gentle products are best near the sealant. Strong solvents can soften or mark it.
Shower screen leaks can go unnoticed. It can damage the floor or the ceiling below before you spot it.
