When it is not the sealant
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Leaks from the roof covering or flashing (a roofer’s job)
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- A frame that needs repairing or replacing
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly before booking.
Surfaces we seal
- Rooflights
- Glass balustrade bases
- Conservatory frames
- Glass-to-glass joints
- Glass-to-frame joints
- Shower screens
Glazing silicone in Lower Horncroft
Many conservatory leaks come down to failed sealant, where glass meets frame or frame meets wall. We find the joint that’s letting water in and renew it and tell you plainly if the cause is something else. If you have leaks from the base of a shower screen and split or lifting silicone on glass, we can put it right.
Homes in small places like Lower Horncroft often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
Big or small, you get the same 12-month guarantee.

What else we do in Lower Horncroft
Lower Horncroft: your questions answered
Do you cover smaller places like Lower Horncroft?
Yes. Lower Horncroft is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Pulborough station?
Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Where are you based?
We are a Crawley-based firm. Our area covers South East England, London and Scotland.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Do the sealants smell?
There can be a smell while the sealant cures. Ventilation helps.
Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that usually means someone at home.
Which silicone is used for glass joints?
A glazing-grade silicone is best. We use neutral-cure glazing silicone and anti-fungal silicone in wet areas.
Can I do it myself?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
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.
Do you need glazing silicone in Lower Horncroft?
Glass and frames expand and contract with the temperature, and they don’t move by the same amount. In time, the sealant splits or pulls away.
People normally contact us after spotting something like this:
- Drips on the inside of a conservatory window
- Leaks from the base of a shower screen
- Leaks where conservatory glass meets the frame
- Sealant that was laid over old silicone and failed
If you look after a building such as Fittleworth CofE Village School, the mastic around its windows and doors needs looking after like any other building’s.
Questions to ask before booking
- How the joint is cleaned and prepared
- The length of the guarantee
- Is VAT in the price?
- How much experience the applicator has
How we quote for glazing silicone
You’ll get a clear quote before any work starts. It’s based on:
- Which sealant suits the joint
- Working hours on commercial sites
- The old material and how stubborn it is
- The size of the job
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and agree the price before starting.
What we need to know
Before you ask for a quote, have a think about:
- Any access issues, like height or stairs
- Roughly how big the job is
- Photos by email, if that is easy
- The problem you’ve noticed
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
Windows and doors in Lower Horncroft
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Bignor Roman Villa (about 2.2 miles south-west) are a reminder that the area around Lower Horncroft 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 live in an older home near Church of St Agatha, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For landlords with property near Pulborough station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Squeegee the shower screen after each use
- Use a gentle glass cleaner and a soft cloth
- Avoid scraping close to the bead
- Get a new leak looked at quickly
Keep conservatory gutters clear, so water drains away from the joints. Overflowing gutters can cause leaks of their own.
Don’t leave lifting or mouldy silicone on glazing. Peeling silicone lets water in behind and the leak gets worse.
Work for landlords, hotels and businesses
Landlords and agents in Lower Horncroft can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will quote.
How the visit works
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and clear up. It normally takes a few hours, depending on how many joints need doing. Somewhere as small as Lower Horncroft, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- We lay the new bead and tool it smooth.
- We check the finished joints and test with water where it’s safe.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any leaks or damp you’ve noticed
