What happens if it’s left?

A leaking joint will not fix itself. Left, water can mark floors, damage plaster and rot timber, so it pays to deal with it early. Homes in smaller places like Boyn Hill can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.

We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or drop us an email.

Glazing silicone for homes and businesses in Boyn Hill

Across Boyn Hill, we reseal glazing joints in homes, offices and hotels. From conservatories to shower screens, it’s the same careful method. If you have leaking glazing joints on a rooflight and leaks where conservatory glass meets the frame, we can help, on glass-to-frame joints, glass-to-glass joints and shower screens alike.

In smaller places like Boyn Hill, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.

Whatever the size of the job, it’s backed by our one-year guarantee in Boyn Hill and across Windsor and Maidenhead.

FAQs for Boyn Hill

Is Boyn Hill within the area you cover?

Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

I let a flat near Maidenhead station. Can you help?

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

How long does glazing silicone take?

As a guide, most jobs take a few hours for most jobs. Bigger jobs take longer.

What do you need from me for a quote?

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

Can a conservatory leak be sealed?

Yes, when the leak is a failed sealant joint. If the cause is the roof, a panel or a unit, we will say so.

Can you do several jobs on one visit?

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

Why not top up the existing silicone?

It doesn’t last. Fresh silicone won’t bond to cured silicone, so we remove the old sealant and clean the joint.

Can you reseal the base of a glass balustrade?

We can, if the base joint is sealed. Send us pictures and we will take a look when you phone 0345 464 0079 or email us.

What happens on the day

On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes anything from an hour or two to most of a day, depending on the size of the job, including the tidy-up. Parking around Boyn Hill is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.

  1. We trace the leak and confirm it’s a sealant joint.
  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.

How to prepare

  • Mention if the joints have been sealed before
  • Let us know about stairs, lifts or work at height
  • Let us know if you’ve seen damp or leaks

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. When it suits you, ring 0345 464 0079 or drop us an email.

Different surfaces, different methods

Glass-to-frame joints

The sealant must stick to glass and frame alike. We choose a product that suits both.

Rooflights

Rooflight leaks can come from the sealant or the roof. We check which it is.

Windows and doors in Boyn Hill

Historic houses like Dorney Court (about 3.1 miles east) are a reminder that the area around Boyn Hill 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’s traditional sand mastic. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

For site and facilities teams at buildings such as Larchfield Primary and Nursery School, larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around All Saints' Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Signs you need glazing silicone in Boyn Hill

Shower screen silicone gets wet every day. Mould grows into the bead and the joint starts to lift.

Signs it’s time to call us include:

  • A quick top-up bead that didn’t last
  • Drips on the inside of a conservatory window
  • Glass-to-glass joints that have split
  • Water escaping where a screen meets the wall

Letting a property close to Maidenhead station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows.

  • Whether they’re fully insured
  • What preparation is included
  • Who turns up on the day

Our hiring checklist

How we quote for glazing silicone

You will get a clear quote before we start. It’s based on:

  • The number and length of the joints
  • Mould in or behind the old joints
  • The number of rooms or windows
  • The product the joint needs

Combining jobs into one visit usually makes better use of the time than several visits. We will give you a clear quote for the lot.

What we need to know

Before you ask for a quote, have a think about:

  • Whether it has been sealed before
  • The problem you’ve noticed
  • The type of property
  • Where the job is, and your postcode

Call for a quick quote, or email us if that is easier. Describe what needs sealing and we’ll talk you through the work.

How to look after the new joints

Good habits help new joints last longer. Our tips:

  • Use a gentle glass cleaner and a soft cloth
  • Don’t leave a drip for the next storm
  • Keep conservatory gutters clear of leaves
  • Keep air moving in the conservatory

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

Conservatory leaks rarely stay small. Water runs along frames and down walls so it’s best dealt with straight away.

What we can’t put right

We’d rather tell you now than do work that will not last, so these are the limits:

  • Cracked or broken glass
  • Frames that have decayed or split
  • Water coming through the roof rather than a sealant joint

If in doubt, phone 0345 464 0079 or email us and we will say what we think before booking.
