Glazing silicone for Tower Hill homes and businesses

Glazing silicone in Tower Hill, done properly

We don’t replace glass, and misting between panes means a failed sealed unit. What we do is the silicone around the glass and that is often where the water gets in. We work on glass-to-glass joints, glass-to-frame joints and conservatory frames, and common reasons people get in touch are shower screens leaking along the wall or tray and conservatory leaks at frame and glazing joints.

Homes in small places like Tower Hill often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.

Whatever the size of the job, you get the same 12-month guarantee.

Signs you need glazing silicone in Tower Hill

UV light ages silicone, especially on conservatory roofs. Old silicone hardens, cracks and loses its grip to the glass and frame.

Keep an eye out for these signs:

  • Silicone pulling away from the glass
  • Water getting into a conservatory at the joints
  • Mouldy sealant around glass panels
  • Shower screens leaking along the wall or tray

For landlords with property near Hemel Hempstead station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

How to choose a mastic man

What the job involves on each surface

Glass balustrade bases

The base joint is cut out and resealed. We do not install or replace glass.

Glass-to-glass joints

Where two panes meet, the silicone joint takes all the movement. The bead needs to be tidy and fully bonded.

How it works

Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours for most jobs. Somewhere like Tower Hill needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. First we agree the joints to be done.
  2. Old sealant is removed from the glass and frame.
  3. We clean and prepare the joint.
  4. New glazing silicone goes in and is finished neatly.
  5. We inspect the work and test it where we can.

Before we arrive

  • Tell us about access, such as stairs, a lift or high-level joints
  • Tell us if parking is tricky
  • For business premises, tell us about site rules or sign-in

Frames and glazing around Tower Hill

Historic houses like Chenies Manor House (about 2.8 miles south-west) are a reminder that the area around Tower Hill has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Homes close to Church of St Paul include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in. Managing a site like Kings Langley School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Tower Hill: your questions answered

Can you do glazing silicone in Tower Hill?

Yes, Tower Hill is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.

Do you cover smaller places like Tower Hill?

Yes, Tower Hill is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Is it enough to run a bead over the old sealant?

A top-up rarely holds. Fresh silicone will not bond to cured silicone so we take it all out and start clean.

How long will you be here?

Most jobs take a few hours, depending on how many joints need doing, including the preparation. We’ll confirm how long when we quote.

How long should I leave it?

Different products cure at different speeds, so follow the cure time we give you.

Can I choose the sealant colour?

Most of the time, yes. We’ll tell you which colours the right product comes in.

Is there any odour?

It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.

Where do you work from?

We work from Crawley. We cover Tower Hill and the rest of Hertfordshire.

Can I do it myself?

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.

Why act early in Tower Hill

A leaking joint won’t fix itself. Water can damage frames, walls, flooring and furniture, so it pays to deal with it early. Around Tower Hill, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.

Why us?

  • We agree the colour with you first
  • White, clear, grey or another colour, product permitting
