Glazing silicone in West Kensington

Glazing silicone in West Kensington, done properly

We renew glazing silicone on conservatories, rooflights and glass panels plus shower screens and the bases of glass balustrades. Each joint is cut out, cleaned and resealed. If you have mouldy sealant around glass panels and water running down inside the glass, we can help, on glass-to-glass joints, rooflights and shower screens alike.

Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out.

The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

FAQs for West Kensington

I let a flat near Kensington Olympia station. Can you help?

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

Is parking a problem for a job in West Kensington?

In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.

Which products do you use?

It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

Do you reseal glass shower screens?

Yes, we do these often. We use anti-fungal silicone suited to bathrooms.

How much does glazing silicone cost in West Kensington?

It depends on the job, so we quote each one individually. To get one, ring 0345 464 0079 or drop us an email with a short description of the job.

Do you offer different sealant colours?

Generally, yes. Sealants come in white, clear, grey and other colours for many products, and we’ll agree it with you first.

Can you quote for more than one area?

Yes. Tell us about everything you’d like done.

Is there any odour?

There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.

West Kensington homes and the weather

In a converted house or block, who looks after the windows depends on the lease, so check that before you book. With historic houses such as Garden Lodge (about 0.4 miles north-east) nearby, there’s older building stock in the area around West Kensington as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.

For an older house near a landmark such as St Cuthbert's, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as The Fulham Boys School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

DIY versus a professional finish

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

How the visit works

All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes a few hours for most jobs. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.

  1. First, we check where the water gets in.
  2. The failed silicone is cut out without marking the glass or frame.
  3. We clean the glass and frame so the new silicone bonds.
  4. We lay the new bead and tool it smooth.
  5. Each joint is checked and, where possible, water-tested.

How to prepare

  • Let us know if you’ve seen damp or leaks
  • Plan for the work area to be out of bounds to pets and children
  • Let us know about parking restrictions

Common problems we fix in West Kensington

Glass and frames expand and contract with the temperature, and they do not move by the same amount. Over years, that movement tears the silicone.

The most common problems we see are:

  • Water tracking down the inner face of the glass
  • Sealant that was laid over old silicone and failed
  • Water getting into a conservatory at the joints
  • Glazing silicone that has cracked or come away

For landlords with property near Kensington Olympia station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

What your quote should include

  • What insurance they hold
  • Which sealant they’ll use, and why
  • What the cure time is
  • How the joint is cleaned and prepared

How to choose a mastic man

Surface by surface

Shower screens

Mouldy or lifting sealant on a screen leaks. A full reseal sorts it.

Conservatory frames

Exposed frame joints wear with the weather. A fresh bead seals them again.

Leave it or put it right?

A quick bead over the old sealant might stop a drip for a while, but silicone does not stick to silicone, and the leak generally returns. A proper reseal is the lasting answer. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in West Kensington, the repair is bigger than a sealant job.

Combining jobs into one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.
