Trusted glazing silicone in Steep Marsh

What the job involves on each surface

Glass balustrade bases

We reseal the joint where the glass meets the base channel. We do not install or replace glass.

Shower screens

Silicone holds the water in on frameless screens. We renew it without marking the glass.

About our glazing silicone in Steep Marsh

Sealant on glazing doesn’t last for ever. Weather and movement take their toll, and once it cracks, water follows. Resealing puts that right. Typical jobs include glass-to-glass joints that have split and water tracking down the inner face of the glass, across rooflights, glass-to-glass joints and conservatory frames.

Outdoor sealant needs dry, clean surfaces, so work on frames around Steep Marsh is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.

There’s a 12-month guarantee on every job, large or small.

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.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

The process

Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from an hour or two to most of a day, depending on the size of the job. For a village or hamlet like Steep Marsh, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We look at the glazing and agree which joints need resealing.
  2. Old sealant is removed from the glass and frame.
  3. The surfaces are cleaned with a suitable solvent.
  4. New glazing silicone goes in and is finished neatly.
  5. The joints are checked before we leave.

What we are called out for in Steep Marsh

UV light ages silicone and roof joints get the most sun. It goes brittle, cracks and stops sticking on the glass.

Common reasons people contact us include:

  • A quick top-up bead that didn’t last
  • Water getting into a conservatory at the joints
  • Split or lifting silicone on glass
  • Rooflight joints letting water in

Schools such as Steep Church of England Voluntary Controlled Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

  • How the colour is chosen
  • Whether VAT is included
  • Who does the work, and how experienced they are

  • Condensation trapped between two panes
  • A broken pane or roof panel

What glazing silicone looks like in Steep Marsh

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

Rented homes near Petersfield station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. Homes close to Church of All Saints include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.
