How we handle glazing silicone in Headstone
Glass replacement is not something we do and a misted double-glazed unit needs a glazier. What we do is the silicone around the glass, which is where many leaks start. We work on glass-to-glass joints, glass-to-frame joints and conservatory frames, and the jobs we see most are new silicone smeared over old sealant and shower screens leaking along the wall or tray.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. The mastic around them dries out and cracks with age, which is when draughts and damp patches appear in homes in Headstone.
All our work is covered by our 12-month guarantee.

The process
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and tidy away. It generally 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. Mention any building rules, key holders or managing agents when you book.
- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- We clean the glass and frame so the new silicone bonds.
- A neutral-cure glazing silicone is applied and tooled.
- Each joint is checked and, where possible, water-tested.
Preparing for the visit
- Clear the area around the work
- For indoor joints, keep the area dry beforehand if you can
- Mention any parking rules near the property

Glazing silicone in Headstone: local notes
The South East is one of the drier parts 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 Headstone Manor (about 0.6 miles south-east) nearby, there’s older building stock in the area around Headstone as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For landlords with property near Headstone Lane station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. If you look after a building such as Pinner Park Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Landlords, agents and businesses in Headstone
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will quote.
How the job changes by surface
Rooflights
Rooflights get the full force of the weather. The sealant around the glass and frame wears faster than most.
Glass balustrade bases
The base joint is cut out and resealed. Glass fitting is a separate trade.
When to call us in Headstone
Not every leak is a sealant problem: failed roof panels, slipped glazing bars and blocked gutters cause them too. We find the cause before we seal anything.
These are the problems we are asked about most:
- A quick top-up bead that didn’t last
- Leaking glazing joints on a rooflight
- Glazing silicone that has cracked or come away
- Stained, discoloured glazing silicone
As a London address, Headstone can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
Before booking anyone
- Are they insured?
- What happens if they find a problem under the old sealant
- How much experience the applicator has
- How the surfaces are prepared before sealing
Keeping the joints in good condition
Looking after new joints is easy:
- Inspect the sealant on glazing annually
- Keep conservatory gutters clear of leaves
- Keep scrapers and blades away from the silicone
- Use a gentle glass cleaner and a soft cloth
On shower screens, wipe or squeegee after use and let the room air. 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 before you spot it.

What else we do in Headstone
Why act early in Headstone
You do not need new glazing because the sealant has gone. Sound glass and frames generally just need resealing, and we will tell you if that’s not the case. 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. Dealing with it early is far simpler for homes in Headstone.

Questions from Headstone
Can parking be tricky for a visit in Headstone?
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.
Can you help a landlord with a rental near Headstone Lane station?
Yes. We work for landlords and agents as well as householders, and several properties can go on one quote. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Do you cover Headstone?
Yes, we do. Our applicators work in Headstone, and the service is the same as everywhere else.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints.
What do you need from me for a quote?
A short description and the location, with photos by email if possible. If we need more, we will ask.
When is the sealant fully cured?
It depends on the product. Before we leave, we will tell you the cure time.
Will the old sealant be removed?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
