Glazing silicone in South Heighton

Glazing silicone in South Heighton, done properly

Glass replacement isn’t something we do and a misted double-glazed unit needs a glazier. Our work is the sealant joints, which is where many leaks start. We work on glass balustrade bases, glass-to-glass joints and rooflights, and common reasons people get in touch are drips on the inside of a conservatory window and mouldy sealant around glass panels.

Outdoor sealant needs dry, clean surfaces, so work on frames around South Heighton is planned for dry weather. Let us know about access to all the frames, upstairs ones included.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Windows and doors in South Heighton

South Heighton is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on glazing joints and frame seals, which can dry out and crack sooner where a building faces the weather. Historic houses like Monk's House (about 2.9 miles north-west) are a reminder that the area around South Heighton 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 look after a building such as Denton Community Primary School and Nursery, larger buildings have plenty of frames, and the mastic around each one ages. Rented homes near Newhaven Town station change hands often, and leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. If you live in an older home near Church of St Leonard, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

South Heighton is about 1 mile north of Newhaven, in East Sussex. Every kind of property in South Heighton is covered for glazing silicone, old or new, large or small.

The process

Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from an hour or two to most of a day, depending on the size of the job. Somewhere as small as South Heighton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First, we check where the water gets in.
  2. We remove the old sealant carefully.
  3. The joint is cleaned and degreased.
  4. We lay the new bead and tool it smooth.
  5. Each joint is checked and, where possible, water-tested.

Before we arrive

  • Mention if the joints have been sealed before
  • Tell us about any water getting in
  • Plan for the work area to be out of bounds to pets and children

Quotes for glazing silicone in South Heighton

We quote each job individually. This is what makes a difference:

How the job changes by surface

Conservatory frames

Frame joints face sun and rain all year. Renewed sealant keeps water out.

Glass balustrade bases

Outdoor balustrade joints face the weather. Renewing the sealant keeps water out of the channel.

Aftercare tips

Simple care keeps the joints in good condition. We recommend:

  • Check the silicone on glass every year or so
  • Don’t use a blade near the sealant
  • Ventilate the conservatory to cut condensation
  • Use a gentle glass cleaner and a soft cloth

Gentle products are best near the sealant. Strong solvents can soften or mark it.

Act on black or lifting silicone early. Once it starts to peel, water gets behind it and the leak gets worse.

South Heighton: your questions answered

Does living near the coast affect glazing silicone in South Heighton?

Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.

Is South Heighton within the area you cover?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Can a conservatory leak be sealed?

It depends on the cause. Failed glazing and frame joints can be resealed, but roof panels and structural problems need a conservatory specialist or roofer.

I’m a tenant. Can you help?

Yes. Ask your landlord first, and we can send them the quote if that helps.

Can you work on commercial sites?

Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.

Is there any odour?

Sometimes, a little. It fades as the sealant cures, and ventilation helps.

Can you do several jobs on one visit?

Yes. Tell us about everything you’d like done and you’ll get one quote.

What should I tell you?

The location, the problem and the rough size of the job. Photos by email help too.

When it isn’t the sealant

To be straight with you, there are a few things sealant won’t fix:

  • Rotten or badly damaged frames
  • A roof that has moved or dropped
  • Failed flashing around a conservatory

Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly before booking.

Surfaces we seal

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

DIY sealant or a professional job?

The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
