How to look after the new joints

To keep the joints looking good and working properly:

  • Use gentle products around the joints
  • Use a gentle glass cleaner and a soft cloth
  • Ventilate the conservatory to cut condensation
  • Run a squeegee over the glass when you’re done

Keep conservatory gutters clear, so water drains away from the joints. Blocked gutters can push water where it shouldn’t go.

A leaking shower screen may not show at first. It can damage the floor or the ceiling below before you spot it.

Glazing silicone in Barford St John

Glazing silicone is a maintenance item. Sun, rain and movement wear it down, and once it cracks, water follows. Resealing puts that right. We work on shower screens, glass-to-glass joints and conservatory frames, and the jobs we see most are shower screens leaking along the wall or tray and glazing silicone that has cracked or come away.

Mastic can only go onto a dry, clean joint, so window work in Barford St John is booked around the forecast. Let us know about access to all the frames, upstairs ones included.

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

What happens if it’s left?

Fixing a leaking screen early protects what’s underneath. Water from a failed joint can soak into the floor before it shows. Older cottages and farmhouses around Barford St John can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first.

How it works

When we arrive, we look over the joints with you first. Surfaces next to the work are protected before we start. The work normally takes a few hours for most jobs. For a village or hamlet like Barford St John, 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. First, we check where the water gets in.
  2. We remove the old sealant carefully.
  3. We clean the glass and frame so the new silicone bonds.
  4. A neutral-cure glazing silicone is applied and tooled.
  5. Each joint is checked and, where possible, water-tested.

Before we arrive

  • For indoor joints, keep the area dry beforehand if you can
  • Tell us about any previous sealing or DIY attempts
  • Clear the area around the work

Windows and doors in Barford St John

The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Broughton Castle (about 3.3 miles north) are a reminder that the area around Barford St John has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.

If you let a flat or house near Kings Sutton station, glazing joints are worth checking at the end of a tenancy, before a small leak grows. For site and facilities teams at buildings such as The Warriner School, the mastic around its windows and doors needs looking after like any other building’s.

Common problems we fix in Barford St John

The wrong sealant is a common cause. Not every silicone sticks properly to glass and vinegar-smelling acetoxy silicone can attack some metals.

Look out for these signs:

  • Water escaping where a screen meets the wall
  • Conservatory leaks at frame and glazing joints
  • Water tracking down the inner face of the glass
  • Silicone pulling away from the glass

If you live in an older home near Church of St John, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How to choose a mastic man

DIY versus a professional finish

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

A careful DIYer can reseal a simple joint, 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.
