Glazing silicone for Offham homes and businesses

How the job changes by surface

Shower screens

Silicone holds the water in on frameless screens. We reseal without scratching the glass.

Rooflights

Rooflights get the full force of the weather. The sealant around the glass and frame wears faster than most.

Glazing silicone for homes and businesses in Offham

Glass replacement is not something we do and a misted double-glazed unit needs a glazier. What we do is the silicone around the glass, which is where many leaks start. If you have leaking glazing joints on a rooflight and cracked silicone between glass panels, we can put it right, on conservatory frames, glass balustrade bases and glass-to-glass joints alike.

Somewhere as small as Offham, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.

We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

When something else is needed

We won’t take on work that will not last, so here’s what sealant can’t put right:

  • A broken pane or roof panel
  • A sealed unit that has misted inside
  • Frames that have decayed or split

If you are not sure, just phone 0345 464 0079 or email us and we will give you a straight answer before booking.

Where we work in Offham

  • Rooflights

Landlords, agents and businesses in Offham

We regularly work with letting and managing agents. Tell us the address, the job and how access works.

Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can go on one quote.

What we do, step by step

You do not need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the work takes anything from an hour or two to most of a day, depending on the size of the job for a typical job. Somewhere as small as Offham, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First, we trace the leak and check it’s coming through a sealant joint.
  2. We cut out the failed silicone, taking care of the glass and frame.
  3. We clean the joint with a solvent that suits the glass and frame.
  4. New glazing silicone goes in and is tooled to a neat finish.
  5. We check the joints and, where safe, run water over them.

Preparing for the visit

  • Let us know if you’ve seen damp or leaks
  • Mention any parking rules near the property
  • For indoor joints, keep the area dry beforehand if you can

Glazing silicone in Offham: local notes

Historic houses like Anne of Cleves House (about 1.7 miles south-east) are a reminder that the area around Offham has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. 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 Cooksbridge station change hands often, and glazing joints are worth checking at the end of a tenancy, before a small leak grows. If you live in an older home near Church of St Peter, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Can I do it myself?

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.

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.

Do you need glazing silicone in Offham?

New silicone over old silicone will not bond. Many failed joints we see have been topped up rather than cut out, and water gets between the layers.

Common reasons people contact us are:

  • Leaks from the base of a shower screen
  • A quick top-up bead that didn’t last
  • Glazing silicone that has cracked or come away
  • Failed joints on frameless glass

Managing a site like Wallands Community Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

Do the sealants smell?

Possibly a little. It fades as the sealant cures.
