Glazing silicone in Otterbourne

About our glazing silicone in Otterbourne

Glazing silicone is a maintenance item. Weather and movement take their toll and cracked joints let water in. Resealing puts that right. We are often asked to deal with water tracking down the inner face of the glass and failed joints on frameless glass, across conservatory frames, rooflights and glass-to-frame joints.

Around Otterbourne, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.

All our work is covered by our 12-month guarantee.

FAQs for Otterbourne

Is Otterbourne within the area you cover?

Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Can you help a landlord with a rental near Shawford station?

Yes, we work for landlords and letting agents. Just call 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.

Is it enough to run a bead over the old sealant?

A top-up rarely holds. Fresh silicone will not bond to cured silicone so we take it all out and start clean.

Can you fix a leaking conservatory?

Often, if the leak is at a sealant joint. We trace the leak first before any sealing.

Where is Mr Mastic based?

We work from Crawley. We cover Otterbourne and the rest of Hampshire.

Can you reseal the base of a glass balustrade?

Yes. The old sealant is removed and the joint resealed using a sealant that suits the materials.

How long does the job take?

It depends on the size of the job, but as a guide it takes a few hours for most jobs. We will give you a better idea when we quote.

What should I tell you?

Let us know what needs doing and where, with photos by email if possible. We’ll ask anything else we need to know.

DIY versus a professional finish

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.

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Aftercare tips

Looking after new joints is easy, and it makes a real difference:

  • Ventilate the conservatory to cut condensation
  • Look over the glazing joints once a year
  • Wipe the screen down after showering
  • Clean glass with a mild cleaner and a soft cloth

Clear the conservatory gutters regularly so water does not back up against the seals. Blocked gutters can push water where it shouldn’t go.

Shower screen leaks can go unnoticed. Water can soak into the floor or reach the room below long before you see it.

Surface by surface

Shower screens

Frameless screens rely on silicone at the base and wall. We reseal without scratching the glass.

Glass balustrade bases

Balustrade bases are exposed outdoors. Renewing the sealant keeps water out of the channel.

For landlords and businesses

Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.

Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.

What glazing silicone looks like in Otterbourne

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.

If you live in an older home near Church of St Matthew, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as Otterbourne Church of England Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. Letting a property close to Shawford station? Then a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

Why it’s worth doing now in Otterbourne

You don’t need new glazing because the sealant has gone. Sound glass and frames generally just need resealing, and we’ll tell you if that’s not the case. In a small place like Otterbourne, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.

What we do, step by step

The work is kept neat and contained to the area we’re working on, so you can get on with your day. Expect the work to take anything from an hour or two to most of a day, depending on the size of the job, and we tell you how long to leave it before we go. In a small place like Otterbourne, access is generally the main thing to plan. 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. The old sealant is removed from the glass and frame without scratching them.
  3. Surfaces are cleaned with a solvent suited to glass and the frame.
  4. We apply a neutral-cure glazing silicone and tool it smooth.
  5. We look over every joint and, where we can, test it with water.

Before we arrive

  • On commercial sites, let us know about site rules
  • Move anything stored near the joints
