About our glazing silicone in Hayes
Glazing silicone that has yellowed, blackened or come away looks poor and can leak. We remove it without scratching the glass or frame before the new bead goes in. We work on rooflights, shower screens and conservatory frames, and the jobs we see most are water escaping where a screen meets the wall and stained, discoloured glazing silicone.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. Over the years, the sealant around them shrinks, cracks and pulls away, letting in draughts and water.
Every job is covered by a one-year guarantee, wherever you are in Greater London.

FAQs for Hayes
Can you do glazing silicone in Hayes?
Yes. Our work covers London and the South East, and Hayes is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing.
Is parking a problem for a job in Hayes?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Is balustrade sealant something you do?
Yes. The sealant joint at the base can be renewed. Fitting glass is a separate trade.
Can you reseal a frameless shower screen?
We can. The old bead comes off without marking the glass, and the joints are cleaned and resealed.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you.

What glazing silicone looks like in Hayes
In a converted house or block, who looks after the windows depends on the lease, so check that before you book. Historic houses like Northolt Manor (about 3 miles north-east) are a reminder that the area around Hayes has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Hayes is in London, so parking needs planning: let us know about parking bays, permits or a driveway. If you live in an older home near Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Hayes & Harlington station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

How we quote for glazing silicone
Some jobs are bigger than they look, and some smaller. The main factors:
- The product the joint needs
- Mould in or behind the old joints
- Any working-time requirements on site
- How easy the joints are to reach
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
What we need to know
To make quoting easier, please include:
- What the problem is, such as mould, gaps, leaks or cracking
- The type of property
- A few photos by email, if you can
- How we’d reach the joints
Getting a quote is simple: let us know what needs doing and where and its rough size. A few photos by email make the job easier to understand.
Landlord and commercial work in Hayes
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will give you a quote.
How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Check the silicone on glass every year or so
- Avoid scraping close to the bead
- Check the gutters above the glazing for debris
- Keep air moving in the conservatory
Clear the conservatory gutters regularly, so water drains away from the joints. Blocked gutters can push water where it shouldn’t go.
Cracked glazing silicone means the joint has failed. Resealing now is a small job compared with fixing water damage later.
What happens on the day
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours, depending on how many joints need doing, depending on the size of the job. For a job in Hayes, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- First we agree the joints to be done.
- We cut away the failed silicone.
- The surfaces are cleaned with a suitable solvent.
- New glazing silicone goes in and is finished neatly.
- We inspect the work and test it where we can.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Where the joints are inside, avoid wetting them before we arrive
- Plan for the work area to be out of bounds to pets and children

Different surfaces, different methods
Conservatory frames
Exposed frame joints wear with the weather. A fresh bead seals them again.
Shower screens
Black or peeling silicone on a screen lets water out. A full reseal sorts it.
Leave it or put it right?
Resealing cannot fix a failed unit or a cracked panel. We say so plainly and point you to a glazier or roofer. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in Hayes.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins.

DIY versus a professional finish
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.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
