Glazing silicone for homes and businesses in Grahame Park

We don’t replace glass and a misted double-glazed unit needs a glazier. What we do is the silicone around the glass and that is often where the water gets in. We work on rooflights, glass-to-glass joints and glass balustrade bases, and people most often call us about glazing silicone that has cracked or come away and glass-to-glass joints that have split.

London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. Over the years, the sealant around them shrinks, cracks and pulls away, which is when draughts and damp patches appear in homes in Grahame Park.

You get a one-year guarantee, the same in Grahame Park as everywhere else we work.

Grahame Park questions

Can parking be tricky for a visit in Grahame Park?

In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.

I let a flat near Mill Hill Broadway station. Can you help?

Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.

Do the sealants smell?

Possibly a little. It fades as the sealant cures.

Can you reseal the base of a glass balustrade?

Yes, where the base is finished with sealant. Photos help us see what’s there when you ring 0345 464 0079 or send us an email.

Which silicone is used for glass joints?

We use a neutral-cure glazing silicone that suits the glass and frame. In bathrooms, we use anti-fungal silicone.

Can you quote for more than one area?

Of course. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.

How long before the joint can be used?

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

Can you just put new silicone over the old?

Silicone doesn’t stick to silicone, so a top-up soon lets water through. The old bead always comes out first.

Signs you need glazing silicone in Grahame Park

Not every leak is a sealant problem: broken panels, roof problems and blocked gutters can all let water in. We find the cause before we seal anything.

These are the problems we are asked about most:

  • Split or lifting silicone on glass
  • Water escaping where a screen meets the wall
  • Drips on the inside of a conservatory window
  • Cracked silicone between glass panels

Grahame Park is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

What to look for in a quote

  • How the surfaces are prepared before sealing
  • Is the old sealant removed completely?
  • How long the guarantee is
  • Whether the sealant suits the joint

Our hiring checklist

Windows and doors in Grahame Park

Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. In a converted house or block, who looks after the windows depends on the lease, so check that before you book.

Schools such as St James' Catholic High School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Mill Hill Broadway station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Can I do it myself?

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

What the job involves on each surface

Glass balustrade bases

Outdoor balustrade joints face the weather. Renewing the sealant keeps water out of the channel.

Rooflights

Water around a rooflight isn’t always the sealant. We check which it is.

What happens on the day

Every visit runs the same way: we check the joints, protect the area around them, carry out the job and tidy away. Most jobs take a few hours, depending on how many joints need doing. In Grahame Park, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.

  1. We look at the glazing and agree which joints need resealing.
  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. The joints are checked before we leave.

Getting ready for the visit

  • Try not to wet indoor joints just before the visit
  • Let us know about parking restrictions
  • Clear the area around the work

Related advice

Why deal with it now?

Replacing windows or a shower screen isn’t needed for a failed joint. If the glass and frame are sound, new silicone is often all it takes. In a flat in Grahame Park, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.

There are no prices on our website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or drop us an email.

What sealant work cannot fix

Some problems need a builder, plumber or other trade rather than us:

  • Water coming through the roof rather than a sealant joint
  • Condensation trapped between two panes
  • Rotten or badly damaged frames

Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly before booking.
