Glazing silicone in Bower Heath

How it works

On the day, we look over the joints with you first. We protect the surfaces around the joints before any work begins. The work generally takes a few hours for most jobs. Somewhere like Bower Heath needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. We look at the glazing and agree which joints need resealing.
  2. We cut away the failed silicone.
  3. The surfaces are cleaned with a suitable solvent.
  4. New glazing silicone goes in and is finished neatly.
  5. We inspect the work and test it where we can.

Preparing for the visit

  • Mention any leaks or damp you’ve noticed
  • Let us know about stairs, lifts or work at height
  • Where the joints are inside, avoid wetting them before we arrive

Glazing silicone for homes and businesses in Bower Heath

Glazing joints need a sealant made for glass. We use a neutral-cure glazing silicone that is suited to glass and the frame, finished with a neat, even bead. Typical jobs include sealant that was laid over old silicone and failed and drips on the inside of a conservatory window, on shower screens, conservatory frames and glass-to-glass joints.

Around Bower Heath, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.

Our work is backed for twelve months, in Bower Heath and everywhere else we cover.

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

Common questions in Bower Heath

Is Bower Heath in your area for glazing silicone?

Yes. We work across London and the South East, and Bower Heath is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job, and we’ll send you a clear quote.

Is Bower Heath within the area you cover?

Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

How long should I leave it?

That depends on the sealant used, so follow the cure time we give you.

I rent my home. Can I book you?

Of course. Ask your landlord first, and we can send them the quote if that helps.

How do I get a quote for glazing silicone in Bower Heath?

The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.

Is it worth trying it myself?

Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Do you take out the old sealant first?

Yes. All of the old material is cut out and the joint cleaned before resealing.

Can landlords and businesses book you?

Yes, we do. We work in homes, commercial premises and hotels, and we’re fully insured.

Windows and doors in Bower Heath

With historic houses such as Shaw's Corner (about 3.2 miles east) nearby, there’s older building stock in the area around Bower Heath as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.

Managing a site like Sauncey Wood Primary School? Then the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as All Saints, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Can I do it myself?

If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.

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

What affects the quote in Bower Heath

There’s no set price list. What we look at:

  • The number and length of the joints
  • Whether the work is at height
  • The type of sealant required
  • Working hours on commercial sites

Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, ring 0345 464 0079 or email us and we will give you an honest view and a quote.

Helping us quote

To help us quote quickly, let us know:

  • What the problem is, such as mould, gaps, leaks or cracking
  • Photos by email, if that’s easy
  • The address or postcode of the job
  • Any previous sealing or DIY work

We don’t publish a price list, as no two jobs are quite the same. Instead, we give you a clear price for your job. To get started, phone 0345 464 0079 or drop us an email.

How to look after the new joints

A little care helps the new joints last. We recommend:

  • Avoid scraping close to the bead
  • Check the gutters above the glazing for debris
  • Keep harsh solvents off the silicone
  • Check the silicone on glass every year or so

Look over the glazing joints every year or so. Catching a split early keeps the repair small.

If silicone on glass has cracked, water is already getting in. Renewing it early keeps it simple, compared with repairing damaged frames or plaster.

Do you need glazing silicone in Bower Heath?

Sunlight breaks sealant down and roof joints get the most sun. Old silicone hardens, cracks and loses its grip to the glass and frame.

These are the problems we’re asked about most:

  • Water running down inside the glass
  • Silicone pulling away from the glass
  • Water escaping where a screen meets the wall
  • Glass-to-glass joints that have split

For landlords with property near Harpenden station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

What your quote should include

  • When the joint can take water or movement
  • Which sealant they’ll use, and why
  • Whether all the old sealant comes out first
  • The length of the guarantee
