Glazing silicone in Hatfield
Many conservatory leaks come down to failed sealant at the glass-to-frame or frame-to-wall joints. We trace the leak to the joint and reseal it, and if it’s something sealant can’t fix, we will tell you. Typical jobs include water tracking down the inner face of the glass and conservatory leaks at frame and glazing joints, on glass-to-glass joints, glass-to-frame joints and rooflights.
Plenty of homes in a town like Hatfield have had conservatories, patio doors or new windows added over the years. Each one adds more joints to look after, and those joints age at different rates. Sills, frame heads and glazing joints are where leaks generally start.
You get a one-year guarantee, the same in Hatfield as everywhere else we work.

You do not need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the job takes a few hours, depending on how many joints need doing for a typical job. Parking in a town like Hatfield is normally straightforward, but tell us if there’s a driveway or any restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- We look at the glazing and agree which joints need resealing.
- Old sealant is removed from the glass and frame.
- We clean and prepare the joint.
- We apply and tool the new silicone.
- The joints are checked before we leave.

FAQs for Hatfield
I let a flat near Hatfield station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Should the sealant in an older Hatfield home be renewed?
If it hasn’t been replaced for some years, it’s usually worth it. Sealant does not last for ever, and its life depends on use, cleaning and weather.
What does glazing silicone cost?
Size, access and the old material all affect the cost. Call for a quick quote and we’ll talk you through it.
Can I choose the sealant colour?
Generally, yes. Sealants come in white, clear, grey and other colours, and we agree the colour with you before work begins.
Are you fully insured?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Can you reseal the base of a glass balustrade?
Yes. The sealant joint at the base can be renewed. We don’t install or replace the glass.
How long does the job take?
Most jobs take anything from an hour or two to most of a day, depending on the size of the job, including the preparation. We’ll confirm how long when we quote.
Can you quote for more than one area?
Yes. More than one area can go on one quote.
What affects the quote in Hatfield
Every job gets its own quote. This is what makes a difference:
- The old material and how stubborn it is
- How many areas need sealing
- Whether the work is at height
- The type of sealant required
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
What we need to know
Before you ask for a quote, have a think about:
- If someone has resealed it before
- A few pictures by email, if you can
- What the problem is, such as mould, gaps, leaks or cracking
- If it’s domestic, commercial or a hotel
If you’re in Hatfield and need glazing silicone, ring 0345 464 0079 or send us an email. Tell us what the problem is and where, and you will get a clear quote before work begins.
What happens if it’s left?
You don’t need new glazing because the sealant has gone. Sound glass and frames normally just need resealing, and we will tell you if that’s not the case. Black mould and gaps in sealant don’t fix themselves, and in a busy household in Hatfield they spread with every shower and every downpour. Now is the easy time to put it right.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
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.
Work for landlords, hotels and businesses
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will give you a quote.
We also work for property managers and facilities teams. We can quote a run of properties together.
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Use a gentle glass cleaner and a soft cloth
- Keep scrapers and blades away from the silicone
- Keep air moving in the conservatory
- Look over the glazing joints once a year
Gentle products are best near the sealant. Harsh solvents may damage the bead.
Don’t leave lifting or mouldy silicone on glazing. Once it starts to peel, water gets behind it and the leak gets worse.
What the job involves on each surface
Glass balustrade bases
The base of a glass balustrade is normally sealed. When it fails, water can sit in the channel.
Shower screens
A screen’s wall joint and tray joint are where leaks start. Both are resealed with anti-fungal silicone.
Frames and glazing around Hatfield
Historic houses like Hatfield House (about 1 mile east) are a reminder that the area around Hatfield 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. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Bishop's Hatfield Girls' School, the mastic around its windows and doors needs looking after like any other building’s. If you live in an older home near Church of St Luke, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Letting a property close to Hatfield station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows.
