Glazing silicone for Locksbottom homes and businesses

How we handle glazing silicone in Locksbottom

We renew glazing silicone on conservatories, rooflights and glass panels, as well as frameless shower screens and glass balustrade bases. Each joint is cut out, cleaned and resealed. If you have glass-to-glass joints that have split and new silicone smeared over old sealant, we can help.

Many London homes are flats, with windows high above the street. In a converted house or block, the lease generally says who is responsible for the windows, so it’s worth checking before booking.

Big or small, you get the same 12-month guarantee in Locksbottom and across Greater London.

Windows and doors in Locksbottom

In London conversions and blocks, the lease decides who is responsible for the frames, so check that before booking. With historic houses such as Down House (about 2.7 miles south) nearby, there’s older building stock in the area around Locksbottom 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.

If you live in an older home near St Paul, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Schools such as Darrick Wood Infant & Nursery School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Looking after it afterwards

Good habits help new joints last longer. A few tips:

  • Stick to mild cleaners on glass
  • Keep conservatory gutters clear of leaves
  • Act on drips or damp patches early
  • Keep scrapers and blades away from the silicone

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

Conservatory leaks rarely stay small. Water travels along the frame and into the wall so it’s best dealt with right away.

Should I try it myself first?

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

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.

When it isn’t the sealant

It helps to know what we cannot do:

  • A sagging or failing conservatory roof
  • Glass that needs replacing
  • Frames that have decayed or split

If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think before booking.

What we seal

  • Rooflights
  • Conservatory frames
  • Shower screens
  • Glass-to-frame joints
  • Glass-to-glass joints
  • Glass balustrade bases

Why it’s worth doing now in Locksbottom

A quick bead over the old sealant might stop a drip for a while, but new silicone won’t bond to old and water soon finds its way back. Cutting out and resealing properly lasts. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Locksbottom, the repair is bigger than a sealant job.

What you pay reflects the work, not guesswork. That is why we ask a few questions first.

Locksbottom questions

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

Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.

Can you do glazing silicone in Locksbottom?

Yes. Our work covers London and the South East, and Locksbottom is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing.

How long does the job take?

Typically it takes anything from an hour or two to most of a day, depending on the size of the job. Larger jobs naturally take longer, and we will say how long yours will take.

What sealant do you use on glazing?

A neutral-cure glazing silicone suited to glass and the frame. Shower screens get anti-fungal silicone.

Can you quote for more than one area?

Yes, we can. Several rooms, windows or areas can go on one quote.

What does glazing silicone cost?

There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.

Is it possible to redo the silicone on a shower screen?

We can. We remove the old silicone carefully before cleaning and resealing.

Will resealing stop my conservatory leaking?

If the water is coming in through failed sealant joints, yes. If it’s a broken panel, failed unit or roof problem, we will tell you.

Do you need glazing silicone in Locksbottom?

UV light ages silicone, especially on conservatory roofs. Old silicone hardens, cracks and loses its grip on the glass.

Common reasons people contact us include:

  • Leaks where conservatory glass meets the frame
  • Rooflight joints letting water in
  • Water escaping where a screen meets the wall
  • New silicone smeared over old sealant

Locksbottom is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Questions to ask before you book

  • Who turns up on the day
  • Whether they seal over old material or remove it
  • What happens if they find a problem under the old sealant
  • Which sealant they’ll use, and why

How to choose a mastic man

How it works

A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. It normally takes a few hours, depending on how many joints need doing. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.

  1. We start by finding the leak and making sure sealant is the cause.
  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 look over every joint and, where we can, test it with water.

Preparing for the visit

  • Mention if the joints have been sealed before
  • Let us know if you’ve seen damp or leaks
  • For business premises, tell us about site rules or sign-in
