Glazing silicone in Queensbury

Glazing silicone for homes and businesses in Queensbury

Glass and frames expand and contract differently, and the silicone between them takes the strain. When it cracks or lets go, water gets in. We cut it out and reseal with a glazing silicone suited to the joint. We work on glass-to-frame joints, glass balustrade bases and conservatory frames, and people most often call us about split or lifting silicone on glass and new silicone smeared over old sealant.

From mansion-block windows to modern glazing in new flats, London has every kind of frame. The mastic around them dries out and cracks with age, letting in draughts and water.

You’re covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

Landlord and commercial work in Queensbury

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.

When to call us in Queensbury

The wrong sealant is a common cause. Some products do not bond well to glass and vinegar-smelling acetoxy silicone can attack some metals.

The problems people normally mention when they call include:

  • Mouldy sealant around glass panels
  • Water getting into a conservatory at the joints
  • Drips on the inside of a conservatory window
  • Glass-to-glass joints that have split

In the older streets around All Saints Church, the joint between an old wall and a newer frame is generally the first place rain gets in.

Before you book anyone

  • Is VAT in the price?
  • Which sealant they’ll use, and why
  • What the cure time is

Our hiring checklist

What affects the cost of glazing silicone

Call for a quick quote. What matters most is:

  • When we can work, for business premises
  • The number and length of the joints
  • Whether old sealant or filler has to be cut out
  • Mould in or behind the old joints

We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.

What we need to know

You don’t need to know the technical terms. It helps if you can tell us:

  • Pictures of the joints, sent by email
  • Where the job is, and your postcode
  • How many joints, rooms or windows are involved
  • What’s wrong with the joints now

For glazing silicone in Queensbury, phone 0345 464 0079 or email us. Tell us what the problem is and where, and you’ll get a clear quote before we start.

When something else is needed

To be straight with you, there are a few things sealant will not fix:

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

If in doubt, ring 0345 464 0079 or email us and we’ll say what we think before you book.

Surfaces we seal

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

How it works

Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes anything from an hour or two to most of a day, depending on the size of the job. In a London area like Queensbury, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.

  1. We start by finding the leak and making sure sealant is the cause.
  2. The old sealant is removed from the glass and frame without scratching them.
  3. We clean the joint with a solvent that suits the glass and frame.
  4. Glazing silicone suited to the joint is applied and tooled.
  5. We look over every joint and, where we can, test it with water.

Before we arrive

  • Where the joints are inside, avoid wetting them before we arrive
  • Mention any parking rules near the property
  • Mention any tricky access

Why act early in Queensbury

Topping up old silicone can look like a fix, but new silicone won’t bond to old and water soon finds its way back. A proper reseal is the lasting answer. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Queensbury, the repair is bigger than the sealant job would have been.

No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.

Why us?

  • 20+ years of sealant experience
  • A choice of colours where the product allows
  • You choose the colour before work begins
  • Sanitary silicone with an anti-fungal additive in wet areas

Take a look at what affects the cost or our reviews.

Looking after it afterwards

Simple care keeps the joints in good condition. Our advice:

  • Keep harsh solvents off the silicone
  • Run a squeegee over the glass when you are done
  • Open vents or windows to let moisture out
  • Don’t use a blade near the sealant

Check the joints once a year. Catching a split early keeps the repair small, before water gets in.

Cracked glazing silicone means the joint has failed. Renewing it early keeps it simple, compared with repairing damaged frames or plaster.

Queensbury homes and the weather

Historic houses like Headstone Manor (about 2.7 miles west) are a reminder that the area around Queensbury 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. In London conversions and blocks, the lease decides who is responsible for the frames, so check that before you book.

If you let a flat or house near Kenton station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. For site and facilities teams at buildings such as Glebe Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Queensbury questions

Can you help a landlord with a rental near Kenton station?

Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.

Can parking be tricky for a visit in Queensbury?

It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.

What information do you need?

Tell us what needs doing and where, plus pictures if you have them. We will ask anything else we need to know.

Do I have to be there?

We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.

Can you do several jobs on one visit?

Yes, and it often makes sense. Combining jobs makes good use of the visit.

Where do you work from?

Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.

Is a special sealant needed for glass?

A glazing silicone chosen for the joint. Neutral-cure silicone is the usual choice, as some acetoxy types can attack certain metals.

Can you reseal the base of a glass balustrade?

Yes. The old sealant is removed and the joint resealed using a sealant that suits the materials.
