Glazing & conservatory sealant in Frogmore, Hertfordshire
Problem with your glazing joints in Frogmore? We remove the old material, prepare the joints and seal them properly.
- Shower screens leaking along the wall or tray
- New silicone smeared over old sealant
- Cracked silicone between glass panels
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Look over the glazing joints once a year
- Don’t use a blade near the sealant
- Clean glass with a mild cleaner and a soft cloth
- Check the gutters above the glazing for debris
Gentle products are best near the sealant. Harsh solvents may damage the bead.
Cracked glazing silicone means the joint has failed. Renewing it early keeps it simple, compared with repairing damaged frames or plaster.
Glazing silicone in Frogmore, done properly
Not every silicone suits glass. Our applicators use neutral-cure glazing silicone that is suited to glass and the frame, finished with a neat, even bead. We’re often asked to deal with failed joints on frameless glass and split or lifting silicone on glass, across shower screens, glass balustrade bases and conservatory frames.
Mastic can only go onto a dry, clean joint, so window work in Frogmore is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Each job carries a 12-month guarantee, large or small.

Why it’s worth doing now in Frogmore
Replacing windows or a shower screen is not needed for a failed joint. Sound glass and frames usually just need resealing, and we will tell you if that is not the case. Older cottages and farmhouses around Frogmore can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or send us an email.

What sealant work can’t fix
Some problems need a builder, plumber or other trade rather than us:
- Water coming through the roof rather than a sealant joint
- Rotten or badly damaged frames
- Glass that needs replacing

Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
How the job changes by surface
Glass balustrade bases
Balustrade bases are exposed outdoors. A sound sealant joint keeps them tidy and dry.
Glass-to-glass joints
Silicone joins glass panels in many frameless designs. We reseal with a suitable glazing silicone.

Glazing silicone in Frogmore: local notes
Historic houses like High Elms Manor (about 2.8 miles south-west) are a reminder that the area around Frogmore 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. 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.
Schools such as Park Street Church of England Voluntary Aided Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. Letting a property close to How Wood station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows. If you live in an older home near Church of the Holy Trinity, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Frogmore questions
I let a flat near How Wood station. Can you help?
Yes, we work for letting agents and landlords. Just call 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Will you come out to Frogmore?
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.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Is balustrade sealant something you do?
We can. The old sealant is removed and the joint resealed with a suitable product.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What do you need from me for a quote?
A short description and the location. We will ask anything else we need to know.
Can you match the sealant colour?
Normally, yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before any work starts.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
What happens on the day
You do not need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the work takes a few hours, depending on how many joints need doing in most cases. Somewhere like Frogmore needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
