About our glazing silicone in Hertford

Cracked, stained or lifting silicone on glass looks poor and can leak. It comes off cleanly, without marking the glass and reseal the joint. We are often asked to deal with shower screens leaking along the wall or tray and leaking glazing joints on a rooflight, on glass balustrade bases, rooflights and glass-to-glass joints.

In a town like Hertford, older houses sit alongside newer estates, with windows of every age. In every case, the joint between frame and wall is what keeps water out.

All of our work is guaranteed for twelve months.

Aftercare tips

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

  • Use a gentle glass cleaner and a soft cloth
  • Use gentle products around the joints
  • Clear the conservatory gutters regularly
  • Don’t use a blade near the sealant

Gentle products are best near the sealant. Strong solvents can soften or mark it.

Don’t leave lifting or mouldy silicone on glazing. Once it starts to peel, water gets behind it and the leak gets worse.

What affects the quote in Hertford

Your quote is based on your job. We take into account:

  • Any working-time requirements on site
  • Access and height
  • How many rooms, windows or areas are involved
  • Whether old sealant or filler has to be cut out

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Helping us quote

To help us quote quickly, please include:

  • A few pictures by email, if you can
  • If someone has resealed it before
  • Roughly how big the job is
  • The problem you’ve noticed

Getting a quote is simple: let us know the job and the location and its rough size. A few photos by email make the job easier to understand, and we’ll take it from there.

Surface by surface

Glass-to-glass joints

These joints are on show, so a straight, even finish matters.

Glass-to-frame joints

Silicone at the glass edge seals it into the frame. A failed bead lets water in.

How the visit works

When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours for most jobs. In Hertford, parking is rarely complicated, though it helps to know about driveways or restrictions, and let us know if the work is upstairs, in a flat or up high outside.

  1. First we agree the joints to be done.
  2. We cut away the failed silicone.
  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.

Getting ready for the visit

  • Tell us about any previous sealing or DIY attempts
  • Try not to wet indoor joints just before the visit
  • Plan for the work area to be out of bounds to pets and children

FAQs for Hertford

What guarantee comes with glazing silicone in Hertford?

All our work, in Hertford and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.

I let a flat near Hertford East station. Can you help?

Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.

Why not top up the existing silicone?

It doesn’t last. Fresh silicone will not bond to cured silicone, so we remove the old sealant and clean the joint.

Are you an approved applicator?

Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.

Do you come to Hertford?

Yes, we do. Our applicators work in Hertford.

How long before the joint can be used?

It depends on the product and the temperature. Before we leave, we’ll tell you the cure time.

Do you seal glass balustrade bases?

Yes. The sealant joint at the base can be renewed. Fitting glass is a separate trade.

Do you take out the old sealant first?

Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

Honest limits

To be straight with you, there are a few things sealant won’t fix:

  • A broken pane or roof panel
  • A roof that has moved or dropped
  • Leaks from the roof covering or flashing (a roofer’s job)

Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.

Joints and surfaces we work on

  • Shower screens
  • Glass-to-glass joints
  • Rooflights
  • Glass-to-frame joints
  • Conservatory frames
  • Glass balustrade bases

Leave it or put it right?

A new conservatory roof is a big job. Where the water is getting in through sealant renewing the joint is the simpler fix. If the roof is the problem, we will say so. Gaps in sealant and mould in the bead never get better on their own, and in a busy household in Hertford they spread with every shower and every downpour. Replacing the sealant now is the simplest fix.

What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

What glazing silicone looks like in Hertford

The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Schools such as Mill Mead 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 Hertford East station? Then a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. Homes close to Hertford United Reform Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
