Trusted glazing silicone in South Hampstead

Glazing silicone for homes and businesses in South Hampstead

Glazing joints need a sealant made for glass. We use a neutral-cure glazing silicone, which suits glass and most frame materials, and we tool it to a neat, even finish. If you have water running down inside the glass and new silicone smeared over old sealant, we can put it right, whatever the surface.

London has a lot of flats and conversions, where windows are often on upper floors. In a converted house or block, the lease generally says who is responsible for the windows, so it’s worth checking before booking, and access in South Hampstead is something to talk through when you book.

A one-year guarantee comes with the work, just as it does everywhere we cover.

Why it’s worth doing now in South Hampstead

Replacing a conservatory roof is major work. If the leak is a failed sealant joint, resealing is far simpler. If it’s the roof itself, we’ll tell you. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in South Hampstead, the repair is bigger than a sealant job.

Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

What you get with us

  • Old sealant always removed completely
  • 12-month guarantee on every job
  • 4.9 on Google from 180+ five-star reviews
  • Anti-fungal sanitary silicone in wet areas

Quotes for glazing silicone in South Hampstead

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • Whether there’s mould to deal with
  • Which sealant suits the joint
  • The number of rooms or windows
  • Whether old sealant or filler has to be cut out

There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

What we need to know

To make quoting easier, let us know:

  • Roughly how big the job is
  • If someone has resealed it before
  • The address or postcode of the job
  • What the problem is, such as mould, gaps, leaks or cracking

If you are in South Hampstead and need glazing silicone, phone 0345 464 0079 or send us an email. Tell us what the problem is and where, and you will get a clear quote before we start.

What the job involves on each surface

Glass balustrade bases

We reseal the joint where the glass meets the base channel. Glass fitting is a separate trade.

Rooflights

Rooflight glazing joints are cut out and renewed. Leaks from the roof itself need a roofer.

How the visit works

A visit follows a simple pattern: we check the joints, protect the area around them, do the work and tidy away. Most jobs take a few hours, depending on how many joints need doing. In South Hampstead, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.

  1. We find where water is getting in and check whether it’s a sealant joint.
  2. We cut out the failed silicone, taking care of the glass and frame.
  3. The glass and frame are cleaned and degreased.
  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 any sign-in or site rules at work premises
  • Tell us about any water getting in
  • Clear the area around the work

Looking after it afterwards

To keep the joints looking good and working properly:

  • Check the gutters above the glazing for debris
  • Keep air moving in the conservatory
  • Avoid scraping close to the bead
  • Stick to mild cleaners on glass

Squeegee a shower screen after each shower and keep the room ventilated. It helps stop mould getting into the silicone.

A leaking shower screen may not show at first. Water can soak into the floor or reach the room below long before you see it.

Frames and glazing around South Hampstead

Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Winfield House (about 0.9 miles south-east) nearby, there’s older building stock in the area around South Hampstead as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.

As a London address, South Hampstead can be tricky for parking: let us know about parking bays, permits or a driveway. Rented homes near South Hampstead station change hands often, and leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. Managing a site like The UCL Academy? Then the mastic around its windows and doors needs looking after like any other building’s.

FAQs for South Hampstead

Do you cover South Hampstead for glazing silicone?

Yes. Our work covers London and the South East, and South Hampstead is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing, and we’ll send you a clear quote.

Do you take out the old sealant first?

Yes. All of the old material is cut out and the joint cleaned before applying anything new.

When is the sealant fully cured?

Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint before we leave.

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

We can. We remove the old silicone carefully, and the joints are cleaned and resealed.

Will there be a smell?

There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.

Do I have to be there?

For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.

Will resealing stop my conservatory leaking?

In many cases, as long as sealant is the cause. We trace the leak first, so you know what you’re paying for.
