Glazing silicone in Colchester, done properly

Frameless shower screens rely on sealant to keep water in. The joint down the wall and the one along the tray are common leak points, and we reseal both. We work on shower screens, glass-to-glass joints and glass-to-frame joints, and people most often call us about mouldy sealant around glass panels and cracked silicone between glass panels.

Beyond its homes, Colchester has shopfronts, offices and flats with plenty of frames and glazing. Failed joints up there let in water that can go unnoticed for a while.

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

What happens on the day

The work is kept neat and contained to the joints we are treating, so you can get on with your day. The job normally takes a few hours, depending on how many joints need doing, and we tell you how long to leave it before we go. For homes and businesses in busier parts of Colchester, parking needs a little planning. Let us know about stairs, lifts or shared entrances too.

  1. First we agree the joints to be done.
  2. We cut away the failed silicone.
  3. We clean and prepare the joint.
  4. We apply and tool the new silicone.
  5. We inspect the work and test it where we can.

Before we arrive

  • Let us know about earlier repairs to the joints
  • Tell us if parking is tricky
  • Tell us about any water getting in

DIY versus a professional finish

A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

Honest limits

Honest advice matters more to us than a booking, so here’s what sealant cannot fix:

  • Frames that have decayed or split
  • Water coming through the roof rather than a sealant joint
  • A roof that has moved or dropped

If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think before booking.

What we seal

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

What we’re called out for in Colchester

New silicone over old silicone won’t bond. Many failed joints we see have been topped up rather than cut out leaving a path for water.

Any of these means the joints need attention:

  • Failed joints on frameless glass
  • Mouldy sealant around glass panels
  • Leaking glazing joints on a rooflight
  • Split or lifting silicone on glass

If you look after a building such as Colchester Sixth Form College, the mastic around its windows and doors needs looking after like any other building’s.

What to look for in a quote

  • How the surfaces are prepared before sealing
  • Whether you can choose the colour
  • When the joint can take water or movement
  • What happens if they find a problem under the old sealant

How to choose a mastic man

Surface by surface

Shower screens

Black or peeling silicone on a screen lets water out. Cutting it out and resealing fixes it.

Glass-to-frame joints

The sealant must stick to glass and frame alike. We choose a product that suits both.

Glazing silicone in Colchester: local notes

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.

Letting a property close to Colchester Town station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows. In the older streets around Church of St Peter, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Why act early in Colchester

If the problem is a misted unit or a broken panel, sealant will not help. We’ll tell you that rather than seal it anyway and point you to a glazier or roofer. For landlords in Colchester, failed sealant soon turns into tenant complaints about mould, damp or draughts. It’s simpler to sort between tenants than in the middle of a let.

What it costs depends on how much there is to do, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.

What you get with us

  • Approved under the ARBOMaster scheme
  • Neat joints and a tidy finish
  • We never seal over old sealant
  • Quality sealants from Arbo and Everbuild

Colchester: your questions answered

What guarantee comes with glazing silicone in Colchester?

Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.

Do you work for landlords with property near Colchester Town station?

Yes, we work for landlords and agents. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.

Do you hold any approvals?

Yes. Mr Mastic is an ARBOMaster approved applicator.

Does someone need to be in?

It depends on the job. For work indoors, someone needs to let us in.

What do you put in the joint?

It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.

Can you match the sealant colour?

We help you choose a colour that suits. The choice depends on the product the joint needs.

Do you remove the old sealant?

Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.

Can I do it myself?

Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
